PCMark Vantage => 16381

P55H-AK takes the CPU overclocking to 4.2GHz after passing numerous kinds of software stability testing,
while the power requirements are about the same as other P55 products.
In conjunction with the i7 875Kexternal clock, 210MHz can be achieved stably, which is a pretty good performance for the P55 level.
In terms of CPU voltage, we can only get statistics for default voltage during standby mode,
and can only achieve the voltage values of user-set BIOS settings at full speed.
During relatively larger overclocking, some negative effects was still seen; I hope ECS can improve this in the future.

DRAM Efficiency Testing
DDR3 1680 CL8 8-8-24 1T
Sandra Memory Bandwidth - 21889 MB/s
EVEREST Memory Read - 20980 MB/s

DDR3 2000 CL9 9-9-24 1T
Sandra Memory Bandwidth - 25067 MB/s
EVEREST Memory Read - 21868 MB/s

DDR3 bandwidth testing showed better results than other P55 motherboard products,
perhaps because the default parameters were tighter, or perhaps because the OEM fine-tuned it better.
The P55H-AK DDR3 bandwidth performed about as well as the LGA 1366 three-channel bandwidth tested.

3D effects Testing
Three GTX 260 were used for testing, P55H-AK is one of the few that support NVIDIA 3-way SLI P55 products

3DMark Vantage => P28536
CPU SCORE => 52795
GPU SCORE => 24746

Street Fighter IV Benchmark
1920 X 1200 8XAA => 132.97FPS

Devil May Cry 4
DX10 1600 X 1200 8XAA => 109.63/97.68/108.19/125.07 fps

Final Fantasy XIV
1920 X 1080 => 4008

Star Craft II: Wings of Liberty
Settings at High - 62

Lost Planet 2
DX9 1920 X 1200 TEST A - 44.9 fps

DX9 1920 X 1200 TEST A - 40.1 fps

3DMark Vantage and Final Fantasy XIV both support 3-way SLI, so the numbers are much higher than the single-chip GTX260.
However, the testing of other games, which did not support SLI, showed that they were unable to take advantage of its functions.
For many games, not only is there the problem of GPU SLI/CF support, but there is also a great deal of room for improvement for supporting four-core (or more) CPUs.
