One,Introduction: ASUSMaximus XI HeroTo escort. Go on.i9-9900KUnfinished test
At 21:00 on October 19th, i9-9900K was officially released, and we started the related evaluation simultaneously in the fast technology industry. However, due to the extremely limited testing time, we only did some simple basic tests, and now the complete evaluation has finally arrived!
In order to ensure the evaluation quality and deeply tap the potential of i9-9900K, we replaced the motherboard of the test platform with Maximus XI Hero, the top ROG player country of ASUS.
Player country is a super-stable platform customized by ASUS mainly for games and overclocked players. Since its birth, it has been constantly introducing amazing ideas and creativity, and constantly breaking all kinds of overclocking world records. In the past 12 years, the motherboard products of the player country have experienced numerous storms and finally become a generation of kings.
On October 8th, as a supporting motherboard chip for i9-9900K — After the Z390 chipset was released together with the 9th generation Core, ASUS also released three motherboards of player country series simultaneously:Maximus XI FORMULA, Maximus XI GENE of MATX version and Maximus XI Hero(WI-FI). And what we get from fast technology is Maximus XI Hero(WI-FI).
Although Maximus XI Hero is not the top model in the player’s country series, it is not much different from FORMULA in terms of specifications. It adopts 10-phase super alloy digital power supply, comes standard with the top SupremeFX sound module in the player’s country, and can support DDR4 memory with the highest frequency of 4400MHz+.
At the same time, in order to facilitate overclocking novices to enter the overclocking world more easily,Maximus XI Hero also introduced the latest AI intelligent overclocking technology. Players can easily check the overclocking constitution of CPU, the voltage required at various frequencies, etc. in BIOS, and can also set more reasonable parameters to restart after overclocking failure.
Compared with the previous generation of Z370 chipset, the main changes of Z390 are that the chipset natively integrates Wireless-AC Wi-Fi and Bluetooth 5.0, natively supports SDXC expansion card (SDA 3.0), and natively supports six USB 3.1 Gen.2 interfaces. These functions can only be supported by a third-party chip, or an expansion card can be directly purchased and plugged into the motherboard. Maximus XI Hero(WI-FI) has built-in Intel’s top 9560 AC wireless network card, which can provide the highest wireless connection rate of 1733Mbps.
ASUS Maximus XI Hero motherboard parameters are as follows
This test will mainly be carried out from the following aspects:
1. Overclocking potential of i9-9900K and performance after overclocking:
9900K itself has a strong performance, so how far can it overclock, how much improvement can it bring after overclocking, and whether such improvement is worth our efforts.
2. Temperature and power consumption after overclocking:
In the initial evaluation, the power consumption of 9900K silent frequency has far exceeded that of the previous generation of 8086K, so how much power consumption will it reach after overclocking?
3. Test the requirements of 9900K for radiator.：
We will test two air-cooled radiators and one water-cooled radiator to see what grade of radiator can meet 9900K K.
4. Test whether B360 motherboard can completely release all the performance of 9900K:
In fact, most players are not interested in overclocking. In the past, the mid-range B-series motherboards with top processors were very good cost-effective combinations. So, in the 9th generation of Core, can B360 motherboards fully play the performance of the processor when they are matched with 9900K?
In addition to the above, we will also make a brief introduction to the overclocking tutorial, hoping to help players with corresponding needs.
Second, a good horse with a good saddle! Appreciation of ASUS Maximus XI Hero motherboard
There are two versions of ASUS ROG Maximus XI Hero motherboard. We got the one with integrated Wi-Fi. The wireless network card model is Intel AC-9560, which supports 802.11ac protocol and Bluetooth 5.0.
The CPU slot hasn’t changed much, and the LGA1151 interface type is still adopted. The conscience lies in that in addition to supporting nine generations of Core processors, backwards compatibility has eight generations of Core processors.
The power supply part of CPU adopts 8+2-phase power supply design, 8-phase CPU core and 2-phase memory.
External 8+4pin power supply access, the specification is slightly stronger than ROG Maximus X Hero of Z370 chipset. The flatter power input interface can effectively share and reduce the temperature of the power line under the high load of the processor, which is specially designed for the CPU with explosive power consumption of 9900K K.
Close-up of original power supply area. The MOSFET adopts SiC639 MosFET from Vishay Company, which adopts the integrated design of NexFET integrating upper and lower bridges, with extremely low internal resistance, and each MOSFET can output 50A current. 8-phase core power supply means that it can provide 500W input power for 8 CPU physical cores at most, and 2-phase core display power supply.
The capacitor adopts the Japanese Fujitsu MIL series black gold solid-state capacitor, which can work for a long time at a high temperature of 105 degrees. Each phase of power supply is also equipped with a MICRO FINE powdered superalloy inductor.
DIGI+ EPU ASP1400CTB VRM (digital power supply) controller, which can accurately control the voltage.
The heat sink in the power supply area of Maximus XI Hero motherboard weighs nearly 300 grams and is connected by heat pipe, which can effectively and evenly share the heat generated by MOSFET.
In terms of expansion slots, it is equipped with three PCI-E x1 slots and three PCI-E x16 full-size slots, of which the upper two are directly provided by the CPU, which can work in x16 or x8+x8 mode, and the super-alloy reinforcement technology is used, which can reduce the damage to the slots caused by users when plugging in and unplugging the graphics card, and is also beneficial to stability.
In the audio part, SupremeFX sound module and S1220 decoding chip, which have always been used in the player’s country, support 120 dB stereo playback output and 113 dB SNR recording input, and the decoder is wrapped in a metal EMI shield.
The circuit part is equipped with professional nichicon audio capacitor, Sabre Hi-Fi ES9023P converter and Texas Instruments RC 4580 amplifier, which supports CD-level sound quality playback up to 32-bit/192kHz.
Four ruggedized DIMM memory slots for up to 64GB capacity. In terms of frequency, the lowest 2133MHz can support the highest 4400MHz.
This generation of Z390 motherboards are all six SATA3.0 interfaces, but most people don’t need more SATA devices.
The integrated I/O backplane is not only convenient to install, but also provides strong anti-static ability, with built-in Clr CMOS buttons and BIOS Flashback buttons.
Interfaces include 1xPS/2, 1x HDMI 2.0, 1x DP, 2x USB 2.0, 2x USB 3.1 Gen1, 4x USB 3.1 Gen2 (one of which is a Type-C interface), 1x RJ45 gigabit network port, 2xWiFi wireless interface, as well as an S/PDIF optical fiber interface and five audio jacks.
There are many accessories, including a SLI bridge (why not an NVLink bridge), three SATA data, and a set of ASUS e-sports style Wi-Fi antennas.
Third, Kyushu Fengshen GAMMAXX Xuan Bing L240 water-cooled radiator: both value and performance.
In the middle of the front of the box is the renderings of the water-cooled radiator, with the LOGO of Kyushu Fengshen in the upper left and the RGB motherboard types supported by the radiator in the upper right: ASUS AURA, Huaqing POLYCHORME, Gigabyte FUSION READY and MSI MYSTIC LIGHT. The motherboards of the above four companies can directly use the software provided by the motherboards to adjust and synchronize the RGB lighting efficiency of the L240 water-cooled radiator in Xuan Bing. At the bottom is the radiator model: GAMMAXX L240.
After opening the carton cover, you can see the main body of Xuan Bing L240 water-cooled radiator and all accessories.
The water pipe is wrapped with woven net, which is flexible and will not bend and shrink.
There is a water injection port next to the water pipe interface, so players can replace Leng Ye by themselves. However, it should be noted that after replacing Leng Ye by yourself, the after-sales warranty will be lost.
Standard 240 cold row, the size is 274×120×27 mm, and the cooling fins of the cold row are arranged neatly.
The size of the cold head is 91×79×47 mm (length x width x height). The cold head is equipped with a high-powered two-phase four-stage external winding motor, the axis of which is a silent and durable ceramic bearing and pump shaft, and a closed impeller design. At the same time, the micro-channel has been redesigned to optimize the design of E-shaped micro-channel, effectively improving the thermal cycle efficiency and thermal contact area, and achieving better thermal conductivity.
Super-large pure copper base and mirror grinding treatment, which can contact CPU more closely.
The cold head has two connecting wires, one is the traditional 3pin power line, and the other is the RGB synchronization line.
Two 120mm high-performance RGB fans, six high-brightness lamp beads, three lighting modes (static, breathing and color conversion) are standard, which support PWM intelligent regulation and low-noise operation.
The speed of the fan is 500-1800 RPM±10%%, the power consumption is 2.04W, and it can provide 69.34 CFM air volume and 2.42 mmAq air pressure, and the running noise is controlled within 30 dB.
The attached fasteners support Intel LGA20XX, LGA1366, LGA115X, AMD AM4, AM3+, AM3, AM2+, AM2+,FM2+, FM1, which are basically supported by mainstream platforms.
Iv. Preparation before overclocking at 5GHz: Description of BIOS option setting of motherboard.
The overclocking of i9-9900K is different from other mainstream processors of Intel in the past. If the BIOS is not set properly, overclocking of 5GHz is difficult to succeed.
In the BIOS “EzMode "interface, click" manual fan adjustment "’ . There are 8 4pin fan sockets on the MXIH motherboard, each of which can be set with a separate temperature curve.
As shown in the figure, the fan mode is "Manual" on the right, and then we adjust the default 70-degree 100% speed to 50-degree 100% speed of CPU fan.
Click the "Advanced Mode" interface in the lower right corner, and then click the "Advanced tab" above to enter "CPU Settings".This is the most important item.
Adjust the "maximum CPU core temperature" to 110 degrees. The default "AUTO" is 100 degrees. If you don’t adjust this number, you will fail no matter how much voltage overclocking is applied.Although brazing heat conduction is used, it is still easy to reach 100 degrees when overclocking at 9900K K.
Click "Extreme Twerker" above to enter the overclocking setting.
“Ai Overclock Tuner” If it is a high-frequency memory module, you can directly open the XMP settings.
“AVX Indytuvyion core Ratio Negative Offset” This item is to set the AVX frequency offset. When running programs supporting AVX instruction set, the power consumption is explosive. If 9900K wants to impact frequencies above 5GHz, it is recommended to set this number to 1 or 2. At present, there are only a handful of games that support AVX instruction set (maybe none at all), and the reduction of AVX frequency by 200MHz has little effect on the overall performance.
“CPU Core Ratio” CPU core frequency doubling setting, here select "Sync All Cores" to set all cores to the same frequency. Here we adjust the 9900K frequency multiplier to 51, which is 5.1GHz.
"Min.CPU Cache Ratio" and "Max.CPU Cache Ratio"Here is the setting of Ring (cache) frequency. Improving this setting can improve the performance of memory and cache. The default Ring frequency of 9900K is 4.3GHz, so players can adjust the maximum value to 45, preferably not more than 47. When the Ring frequency exceeds 4.7Ghz, the performance gain is very small, but it will cost a lot of voltage, which is not worth the loss. Ring frequencies below 4.7GHz can basically be achieved without pressurization.
“CPU Core/Cache Voltage” Set to "Manual Mode". The processor voltage can be set manually.
“DRAM Voltage” Memory voltage can be set. Generally, it is enough to set the memory bar of B-Die particles below 4GHz to 1.35V V..
"CPU VCCIO Voltage" and "CPU System Agent Voltage" These two items are to set the voltage of the processor memory controller, and it is enough to set the frequency below 4GHz of the memory stick of B-Die particles to 1.15V V.. When it comes to memory particles with poor constitution, it can be adjusted to 1.25V V. The higher this voltage setting is, the higher the power consumption and temperature of the CPU will be.
“DRAM Timing Control” Memory timing and various parameters can be set.
“External Digi+ Power Control” Pressure drop prevention settings can be made.
“Internal CPU Power Management” It may be possible to set that upper limit of processor pow consumption and current.
“AI Features” AI intelligent overclocking is a very practical function. After overclocking fails, it will automatically adjust the appropriate parameters to meet the set frequency.
Enter "External Digi+ Power Control" to set the anti-voltage regulation.
“CPU Load-line Calibration” There are 8 grades. The lower the grade, the more severe the voltage drop under high load. This setting is different for each motherboard, and players need to explore for themselves. For ASUS Maximus XI Hero motherboard, Level 8 is just the voltage drop-off prevention level. It is recommended that players who use this motherboard set it directly to Level 8 when overclocking.
AI intelligent overclocking is the latest overclocking technology of ASUS Z390 player country series motherboards. It can provide the physical information of CPU and tell you how high the current frequency needs to be set to be stable, which is very practical for novices. The BIOS will turn on this function by default, see "Prediction" in the lower right corner.
“Sil Quality”It represents the constitution of CPU. The higher the percentage number, the better the constitution and the better the overclocking potential. Our 9900K physique is 79%, which can only be regarded as the mass physique.
“Cooler” It indicates the heat dissipation capacity of the platform, and the higher the number, the better. Under our numerical value, the L240 of Kyushu Fengshen Xuan Bing is 176pts, the Supreme Treasure of Kyushu Fengshen Twin Towers is 153pts, and the overclocking of 3 Donghai X5 is only about 140.
The number below represents the stable voltage required for the frequency set in that year. 79% of our 9900K needs 1.316V to be stable at 5.1GHz in the Non AVX state, and it needs 1.35V if AVX Offset is not set.
5. overclocking test: it can reach 5.1GHz, but there are conditions.
1. Memory overclocking test
The memory used for testing is Zhiqi F4-3200C14D 8GBx2 package (Magic Light Ji), which uses Samsung B-Die granules and has excellent overclocking performance. We use it to test the overclocking potential of ASUS Maximus XI Hero motherboard, and then we will test the performance of the memory after overclocking.
The memory of ASUS Maximus XI Hero motherboard has a good overclocking ability. Simply setting the memory voltage of 1.35V, the voltages of "CPU VCCIO Voltage" and "CPU System Agent Voltage" are both 1.15V, you can overclock the Chi Fantasy Light Ji to 4000MHz under the time sequence of 18-18-18-52 CR2, which is far from the limit.
Raise the memory voltage to 1.4V, properly raise the timing and memory controller voltage, and the frequency can even reach 4300MHz, but this extreme overclocking method is not recommended.
Compared with the default frequency of 2133MHz, the memory delay is reduced from 60.2ns to 42.9ns after overclocking to 4000MHz. The speed of memory reading, writing and copying has been improved by nearly 80%.
Using MemTest64 program, the memory stability test was carried out for 1 hour and 26 minutes, and the result was perfect, with 0 error.
2. CPU overclocking test
The overclocking potential of i9-9900K is far less than that of the 8086K we tested before, mainly because of the temperature problem (which we will talk about later in the temperature test).
Our 9900K needs 1.25V to run FritzChess test, 1.27V to run CineBench R15 test and 1.32V to pass AIDA64 FPU baking machine test at 5GHz.
As for 5.1GHz, it is necessary to set the AVX Offset parameter to 1 to operate stably at 1.33V V.Otherwise, it is almost impossible for the conventional air-cooled and water-cooled radiators to suppress the temperature of the 9900K baking machine below 110 degrees at a voltage above 1.35V, and the baking machine will inevitably collapse.
The following is a screenshot of CineBench R15 running at 1.33V 5.1GHz:
At 5.1GHz, the single-thread score of CineBench R15 is 220, and the multi-thread score reaches 2197, which is 8% higher than that of silent frequency 2033.
3, overclocking performance test
The following is a summary of the theoretical performance of CPU after overclocking:
Since applications such as POV-Ray and X265 FHD Benchmark will use the AVX instruction set, the temperature can’t be controlled at 5.1GHz, so for the theoretical performance of CPU, we overclock the frequency to 5.0GHz for testing.
After overclocking to 5GHz, the single-core performance is improved by about 1%, while the multi-thread performance is only improved by 6.5%. After all, the whole-core frequency is only 300MHz from 4.7GHz.
At this time, compared with i7-8086K, the performance is nearly 50% ahead, and compared with Ruilong 7 2700X, it can lead by 30%.
The following is a summary of the game performance after overclocking:
Overclocking the CPU and memory stick to 5.1GHz and 4000MHz, respectively, to test the improvement of game performance, and also reducing the memory frequency to 2133MHz, to test the influence of memory frequency on game performance.
Compared with CPU silent frequency+memory 3200MHz, overclocking to 5.1GHz+4000MHz can improve the game performance by less than 3%. The main reason is that most games are played on a platform like 9900K, and even if the resolution of 1080P is used, the graphics card will still become a bottleneck.
After reducing the memory frequency to 2133MHz, the game performance is 5% lower than that of silent frequency.
In addition, because the game frame rate of Survival of the Jedi has changed greatly compared with the previous version after the update, this game is not included in the statistics of performance percentage.
6. Temperature and power consumption test: Both power consumption and temperature explode.
Test whether i9-9900K can be suppressed by Kyushu Fengshen Xuan Bing L240 water-cooled radiator, Kyushu Fengshen Frost Tower Extreme Edition and overclocking three Donghai X5 air-cooled radiator respectively.
The X5 radiator in Donghai, overclocking three, is equipped with five 6mm pure copper heat pipes, and the base uses heat pipes for direct heat dissipation, with a 12cm fan. The official price is 99 yuan.
The famous Kyushu Fengshen Frost Tower Extreme Edition, double tower design, double fans and 6 heat pipes. The heat pipe and Fin are combined by the process of penetrating FIN, and the heat dissipation base is made of pure copper and nickel-plated vapor chamber.
The biggest difference from the standard version of Frost Tower is that the whole radiator has been plated with nickel, which has stronger oxidation resistance; In addition, two fans have been upgraded with UF all-encapsulated rubber, which makes the noise lower. The official price of the radiator is 299 yuan.
Kyushu Fengshen Xuan Bing L240 water-cooled radiator, priced at 699 yuan.
1. CPU temperature test
The temperatures of AIDA64 roaster and CineBench R15 were tested respectively. During the test, the room temperature was 23 degrees, the cooling silicone grease was Arctic MX-4, and the upper limit of BIOS temperature was set to 110 degrees.
The first is the silent frequency temperature test.
The above picture shows the temperature of AID64FPU baking machine with X5 radiator in Donghai, overclocking three. It can be seen that the processor frequency has dropped to 4.2GHz when baking machine. At this time, the core temperature is kept at about 80 degrees, and the internal power consumption of CPU is 148 watts. In fact, when running other test programs at 9900K, the power consumption at the whole core frequency of 4.7GHz is about 150W W. Therefore, it can be considered that the X5 radiator with three frequencies in Donghai can meet the cooling demand of 9900K under silent frequency.
This is the baking temperature of Kyushu Fengshen Xuan Bing L240 water-cooled radiator and AIDA64 FPU baking machine. The baking frequency is 4.5GHz, and the internal work number of the processor is 163W W. At this time, the temperature is also 79 degrees.
The results of the Great Frost Tower Extreme Edition are equivalent to those of Xuan Bing L240 water-cooled radiator, so it will not be posted separately.
Below is the temperature test of overclocking to 5GHz.
At the frequency of 5GHz, both CineBench R15 and AIDA64 FPU tests of overclocking three Donghai X5 radiator directly and instantly broke through 110 degrees, and then crashed, making it impossible to test.
The above picture shows the temperature of the Frost Tower Extreme Edition running CineBench R15. It can be seen that the power consumption of 9900K has reached 212W at a voltage of 1.27V, which cannot be suppressed by ordinary air-cooled radiators. The temperature of the Great Frost Tower Extreme Edition also reached a high temperature of 97 degrees.
When running AID64FPU program, the Extreme Edition of Dashuang Tower, like the X5 radiator in overclocking three Donghai, broke through 110 degrees in an instant, so it could not be tested.
The above picture shows the temperature of Xuan Bing L240 water-cooled radiator of Kyushu Fengshen when it runs CineBench R15. At this time, the internal power consumption of 9900K is 206W, and the temperature of 86 degrees is acceptable.
The above is the temperature of Kyushu Fengshen Xuan Bing L240 water-cooled radiator running AIDA64, which reached a horrible 104 degrees. If the upper limit of U temperature is not raised in BIOS, this test will not continue.At this time, the internal power consumption of CPU has reached an astonishing 264W W. For the 8086K or 7700K with silicone grease heat conduction inside, when the internal power consumption reaches more than 130W, it will break through in an instant, and the advantage of using brazing heat conduction for 9900K is also shown here.
In addition, we can see from the above picture thatThe temperature of the power supply module MOSFET of ASUS Maximus XI Hero motherboard is 89 degrees.This is a very, very good number. Under normal use, the ultimate power consumption of 9900K is only so much. For example, when the power consumption of a 7-phase B360 motherboard reaches 100W, the temperature of its MOSFET can exceed 90 degrees.
Maybe many people don’t care so much about the temperature of the motherboard power supply. At present, the power supply module of most motherboards is generally equipped with an overheat protection of 105℃. After exceeding this temperature, the output current will be automatically reduced and then the CPU frequency will be greatly reduced. In addition, the temperature of the power supply part is too high, which has a great influence on the stability of overclocking.
Summarize the data of temperature test as follows:
As can be seen from the above table, the overclocking three Donghai X5 with a price of 100 yuan can meet the cooling demand of 9900K at silent frequency, but if overclocking is to reach 5GHz, it needs at least a mid-to-high-end air cooling in 300 yuan or direct water cooling at 240℃.
2. Power consumption test
We use Furmark and AIDA64 FPU to fully load RTX 2080 Ti and i9-9900K at the same time, and then read the power consumption of the whole machine from the power meter. The power supply used in the test is a titanium gold power supply that is cool to MasterWatt Maker 1200W W.
In the silent frequency state, the power consumption of double baking reaches 510W W. Considering that there will be games supporting 8 cores in the future, a bronze power supply rated at 600W is the minimum requirement for establishing 9900K+2080 Ti. After overclocking to 5GHz, the power consumption of double baking soared to 680W W. If you want to run stably in the future, you need to buy an 800W bronze power supply. This power requirement has surpassed AMD Ruilong ThreadRipper 2990WX overclocked to 4GHz.
Vii. Test with B360 motherboard: There is a big gap with Z390 motherboard.
In the previous test, we tested the i9-9900K overclocked to 5GHz. Compared with the silent frequency, both the game and the theoretical test have not been greatly improved, and it can also provide enough powerful performance in the silent frequency state. Therefore, for players who do not overclock, is it appropriate to choose a cheap B360 motherboard to match it? Let’s test to verify the feasibility of 9900K matching B360 motherboard.
We found a microsatellite B360M BAZOOKA PLUS motherboard from the warehouse. The motherboard uses 7-phase power supply, and the official retail price is 799 yuan, which is a better one among B360 motherboards. After downloading the latest BIOS from MSI official website and refreshing it, I can support i9-9900K.
1. Theoretical performance test of CPU
CPU-Z
Microsatellite B360M BAZOOKA PLUS scored 570 for single thread and 5572 for multi-thread.
Whether single-threaded or multi-threaded, MSI B360M motherboard is not much different from ASUS MXIH.
CineBench R15
In the CineBench R15 test, the single-thread score of MSI B360M is 212, and the multi-thread score is 1908.
In the test, 9900K can not guarantee the operating frequency of 4.7GHz.
Compared with ASUS MXIH motherboard, the single thread of MSI B360M is only 4 points behind, but the multi-thread gap is 131 points, which is 7% behind.
wPrime
MSI B360M took 28 seconds in the single-threaded test of wPrime 32M and 92.5 seconds in the multi-threaded test of 1024M.
Compared with ASUS MXIH motherboard, the single thread of MSI B360M is only one second apart, and the multi-thread takes 8.5 seconds longer, with a difference of 10%.
POV-Ray
The result of MSI B360M multithreading is 3914PPS.
Compared with ASUS MXIH motherboard, it is 407 points behind, with a gap of nearly 11%.
X264 FHD Benchmark
In X264 FHD Benchmark, the performance of MSI B360M multithreading is 58FPS.
Compared with ASUS MXIH motherboard, it lags behind 3FPS, with a gap of 5%.
Based on the above test data, MSI B360M is not much different from ASUS MXIH motherboard in single-thread performance, but it lags behind about 10% in multi-thread testing.
2. Comparative test of game performance
3DMark Time Spy
The microsatellite B360M got a physical score of 10247 and a graphic score of 13523.
Compared with ASUS MXIH motherboard, the physical score of MSI B360M is 1132 points less, with a gap of 11%. The graphics score is only 100 points, with a difference of less than 1%.
The following is a summary of the game test data:
As can be seen from the above table, there is a gap of 3%~10% between MSI B360M and ASUS MXIH motherboard in the above six games.Overall, it is 5% behind.
3, baking machine test
When the AIDA64 FPU roaster was tested with the MSI B360M BAZOOKA PLUS motherboard,The internal power consumption of the processor is only 110W, which is 40 W lower than the 150W of ASUS MXIH, and the baking machine frequency is less than 4GHz. 110W is more than enough for 8086K, but not enough for 9900K K..As a result, the 9900K has different frequency reductions in various tests when it is matched with the B360 motherboard, which affects the performance release.
VIII. Summary: The premise of successful overclocking of i9-9900K is only temperature.
In the initial stage of overclocking test of i9-9900K, the author took some detours, and when overclocking failed to pass the baking machine, the voltage was increased blindly, which backfired.
For the 9900K,The biggest prerequisite for the success of overclocking is temperature, temperature and temperature (the important thing is said three times). If the test platform is not equipped with an excellent cooling system, even if the voltage is only 1.2V, the temperature of the baking machine can break through 100 degrees in an instant, and then the system collapses quickly. In order to improve the success rate of overclocking, we can only overclock at the lowest possible voltage, use the best motherboard, set the AVX Offset value properly and equip with a radiator with sufficient performance.
According to our test results, the silent i9-9900K has strong enough performance, the theoretical performance is improved by 40% compared with 8086K, and the game performance is also improved by 5%. After overclocking to 5GHz, the performance does not change much, the theoretical performance can be improved by 6.5%, while the game performance is only improved by 3%. Compared with the huge price of overclocking, it is a little bit less than the loss. For players who don’t like tossing, there is no problem in setting 9900K to use in silent frequency.
I9-9900K has a high demand for memory frequency. When using dual-channel 4000MHz memory, compared with dual-channel 2133MHz, the game performance is improved by nearly 7%. You should know that every time Intel upgrades, the game performance of the new generation CPU is only so much higher than that of the old one (for example, the game performance of 900K is only 5% stronger than that of 8086K)..Therefore, if conditions permit, you can try to use high-frequency memory..
Intel’s B-series midrange motherboards with top-level processors in past dynasties are very cost-effective combinations. However, in 9900K, the same routine is no longer applicable.At present, most B360 motherboards on the market can’t meet the huge power consumption demand of 9900K, which leads to the serious frequency reduction of the latter in actual use and the failure to fully release its performance. Therefore, for the choice of motherboards, it is best to choose a Z370 or Z390 motherboard with more than 10-phase power supply.
For the choice of radiator,In the case of no overclocking, although a 100-yuan air-cooled radiator can cope, I suggest you buy a mid-to high-end radiator product above 200 yuan. If you want to overclock, the best choice is water cooling.The core power consumption of 9900K can exceed 250W only, and there are not many radiators that can be suppressed on the market.In addition, when the processor and graphics card are running at high load, it will cause a lot of accumulated heat inside the chassis, which is a disaster for the 5GHz 9900K K. No matter how good the air duct is, it can’t get rid of this heat in time. What’s more, many players now pursue the side-transparent chassis, which further reduces the heat dissipation capacity of the chassis. Therefore, the water-cooled radiator is the most suitable choice for overclocking players.
Perhaps some readers will wonder why the power consumption of thread ripper 2990WX 32 core 400W can be suppressed by 240Water Cooling. Why is it so difficult to reach 9900K? This is mainly because the core area of 2990WX processor reaches 800 square millimeters, while that of 9900K is only 170 square millimeters, and the contact area is too small, even if brazing is used, the huge heat inside the processor cannot be quickly conducted out. To reduce temperature and power consumption, the best way at present is to upgrade to 10nm process.I9-9900K will be the last chapter of 14nm process.
Finally, let’s talk about the ASUS Maximus XI Hero motherboard. The player country series has existed as an overclocking god board since its birth, and MXIH has also inherited the excellent genes of this series. Although "only" only has 10-phase power supply, the SiC639 MosFET it uses not only has an amazing on-current of 50A, but also greatly reduces the on-resistance by integrating the integrated design of upper and lower bridges, so that it can operate at a lower temperature and output stable current under extremely high load, thus greatly providing the stability of overclocking. In our test,When the power consumption of 9900K reaches 260W, the temperature of the SiC639 MosFET does not exceed 90 degrees..
The BIOS of Maximus series motherboards is as powerful and comprehensive as ever, and the new AI intelligent overclocking skill of Maximus XI Hero can provide the physical information of CPU and tell you how high the current frequency needs to be set to be stable, which is very practical for novices.
To put it simply, ASUS Maximus XI Hero is a motherboard born for overclocking..
