ASUS M5A99FX Pro R2.0 Motherboard Testing

Testing the ASUS M5A99FX Pro R2.0 motherboard will involve running it through OCC's test suite of benchmarks, which includes both synthetic benchmarks and real-world applications, to see how each of these products perform. The gaming tests will also consist of both synthetic benchmarks and actual gameplay, in which we can see if similarly prepared setups offer any performance advantages. The system will receive a fully updated, fresh install of Windows 7 Professional 64-bit edition, in addition to the latest drivers for each board and Nvidia GeForce 331.93 drivers for the GTX 770. In the past we had locked the clock speed on the processor to eliminate any easily controlled variables due to processor speed. However there is a difference in how each manufacturer handles the CPU default and boost speeds creating opportunity for one board to deliver a higher level of performance. This variable is a point of difference between boards. The majority of users will run the stock settings making this point a valid concern so we are changing up the test methods to capture this difference.

ASUS M5A99FX Pro R2.0 Motherboard Overclocking:

Overclocked Settings:

Overclocking with the ASUS M5A99FX Pro R2.0 was relatively straightforward. I followed the usual method of disabling any power-saving options, locked in frequencies manually, and set about my way cranking up the speed. To make things move more quickly, after setting the basics in the BIOS, I fired up ASUS AI Suite to start iterating on my settings. After a few rounds through setting and testing I was sitting fat and happy at a very much thermally limited 4715 MHz at 1.43 volts. Any lower on the voltage would yield a failure on core #5 (which was the first one to fail in every single test) and any higher on either the voltage or clocks pushed the CPU into thermal throttling after a few minutes of Prime95. The final settings ended up being 200x23.5, 1.43 volts vcore, and 1.225 volts to the memory controller. All of my testing was done with the H100i cranked up to the unbearable maximum of its two 120mm screamers, but there just wasn't any more headroom to keep it cool under load; the 8350 is not a cool chip when cranked this high. The last 15 MHz came from the board slightly overclocking the FSB even though I locked it in at 200 MHz.
