Tomb Raider 9 (1920*1200, highest picture quality, DX11, 0xMSAA)

Disk read and write test:

AS SSD Benchmark 1.6

calorific test:

Prime95

This evaluation can be mainly divided into three parts. The first part is BIOS trial, the second part is the enhanced performance test, and the last is the calorific test.

Test platform screenshot

The hardware we selected for testing is Inteli7-5960X, public version GTX Titan and 16G 2400MHz four-channel memory. We will also add the test results of the X99M killer motherboard tested earlier on this set of hardware for comparison.

motherboard BIOS trial:

motherboard supports 1080P high-definition BIOS interface, and the operation interface is not much different from other ASRock 9 series motherboards. It is still mainly red and black color matching. The two motherboards are no different in this regard.

Overclocking and voltage adjustment

BIOS provides several simple one-click overclocking solutions. Overclocking can also be manually set through frequency multiplication and BCLK. Voltage adjustment related to overclocking is under the FIVR configuration option, there are three modes: automatic, adaptive and magnification. Manually setting the adaptive and magnification mode can also adjust the compensation voltage value.

Memory Settings The specific memory timing settings in

BIOS are quite complete, and the default memory frequency can be selected up to 2666MHz. The higher frequency needs to be adjusted in the DRAM Frequency OC Preset below, but it will also affect the frequency changes of BCLK.

benchmark performance test:

In order to facilitate users to understand the performance of this motherboard, we added another motherboard as a reference comparison. Due to the accuracy of the test, we generally regard the gap within 3% as an error.

equipped with i7 The ASRock X99X Killer Edition of 5960X is basically the same as the results of the motherboard in all benchmark performance test projects, and the platform normally performs the performance that the hardware should have.

Mumb board temperature test

Temperature test part, we mainly examine the problems of the motherboard CPU power supply part, this part of the temperature is where the motherboard generates a lot of heat, and it is also the key to affect the stability of the motherboard. We used the Fluke Ti25 thermal imager for testing, recording two data when idle (CPU, graphics card is out of load) and full load (CPU is full, graphics card is out of load).

Platform calorific value (left full load and right idle)

After our compilation, the motherboard calorific value is as follows:

Heat value is compared with

Under the default BIOS settings, in the motherboard calorific value test, the ASRock X99X Killer Edition is not much different in the power supply part compared to the X99M Killer Edition. This is mostly because the two boards use the same power supply scale.

4 ASRock X99X Killer Edition Overclocking Test Back to Top

ASRock X99X Killer Edition Overclocking Test:

In the overclocking test, equipped with i7 5960X, we chose a relatively conservative 4.2GHz core frequency for testing to detect the overclocking capability and stability of the motherboard. At this time, the core voltage of is 1.220V.

After overclocking to 4.2GHz, in terms of CPU performance, achieved more than 20% performance improvement compared to the default frequency , and did not crash during the benchmark test and Prime95 roaster test, and the overall overclocking operation was good. It is worth mentioning that this overclocking uses the 4.2Ghz overclocking solution preset on the motherboard. Such a stable overclocking effect can reduce the time spent on debugging by players.

Overclocking calorific value (left full load and right idle)

Overclocking calorific value compared to

After using i7 5960X overclocking 4.2GHz, in the calorific value test, due to the load of the power supply part soaring, the temperature reached 87 degrees after running for a period of full load, which is 20℃ higher than the state under the silent frequency. To ensure the stability of the platform, especially for users who use small chassis, it is not recommended to pursue too high frequency when using this motherboard for overclocking, as long as about 4.2Ghz. Or you can also be creative in the power supply part of the motherboard and add a chassis fan to assist in cooling, which is very playable.
