Testing the ASUS Crosshair V Formula motherboard will include running it through the OCC test suite of benchmarks that include both synthetic benchmarks and real world applications to see how it compates to other boards. The gaming tests will also include a couple of synthetic benchmarks and actual gameplay to see if similarly-prepared setups offer any performance advantages. Each board received a fully updated, fresh install of Windows 7 Professional 64-bit Edition and used the latest drivers for each board and the latest AMD Catayst drivers for the HD 6970. To keep all the tests consistent and eliminate any variables, all the hardware will be tested at the same speeds, voltages, timings, and latencies.


Testing Setup:


Comparison Boards:




Overclocked Settings:

  • Processor: AMD Phenom II X6 1100T at 221.7 x 19, 4213 MHz
  • Motherboard: ASUS Crosshair V Formula

Overclocking the Crosshair V Formula was a dream with the new UEFI BIOS and the TurboV utility. To get started, I pushed the multiplier to 19x, as I have found this to be a sweet spot for the Phenom II X6 1100T I am using. I then booted into the system and used the TurboV utility to tweak the processor's reference clock a bit, adjusting the voltages as I went along. I was able to remain in the OS at 4.3 GHz, but it was not stable so I restarted the system and started where I left off. After a bit of tweaking and playing with the voltages, I was able to keep the system stable at 4.213GHz. Overall, this was a great overclock at about 25%. The final numbers were 19x on the multiplier, with a reference clock speed of 221.7MHz at 1.5 volts on air. Not bad for this chip and the highest I have had on air so far. The Crosshair V Formula features an excellent Auto Tuning utility within the AI Suite. When I ran the fast OC I, the system automatically pulled out a whopping 16% overclock in seconds, putting the CPU at 3.828GHz. On the Extreme setting, it was able to pull out a bit more juice, topping out at 3.91GHz, all with practically no effort.



Maximum Clock Speed:

Each motherboard has been tested for stability at the CPU clock speeds listed when in an overclocked state. These clock speeds will be used to run the test suite and will provide the performance difference increase over the stock settings in the overclocked scoring.
