ASUS Rampage V Extreme Testing:

Testing ASUS' ROG Rampage V Extreme 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 drivers for the NVIDIA 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.

There are more than a few ways to get the most from your CPU using ASUS' top of the line ROG board, the Rampage V Extreme, or for that matter any of ASUS X99 boards due to how well the hardware and software features are integrated from the top to the bottom of the product stack. You have the ability to manually tweak and tune, in the well thought out UEFI BIOS, if you feel you want to row your own boat as an enthusiast. Or, you can go full auto and let ASUS 5-Way optimization tool do all the work for you, if the BIOS is a bit intimidating if you want a true one touch overclock. The best of all is that you can go from one end to the other and mix and match to get your final results. ASUS provides the tools for you as long as you understand where the tools will take you. Due to the complexities of managing the maximum CPU core clock speed, the strength of the memory controller, and the cache ratio, it is a tremendous balancing act to get to the highest clock speed possible with your installed CPU and memory. Last but certainly not least, is the ability to use the auto-overclocking tools in the BIOS in either the EZ or Advanced sections of the BIOS. It's all pretty cool when you sit back and watch it all work.

By manually tuning the parameters to get my Core i7 5960X to 4.6GHz was pretty much a carbon copy of the results I used on the X99 Deluxe. Those were impressive enough, but I just could not pull any more out the silicone that I could on the Deluxe channel board. That says a lot for what you can do with ASUS product stack and confirms that 4.6GHz is my max everyday speed.

To get there, I start with setting the XMP profile for the Corsair Vengeance memory and adjusted the clock multiplier to reach a good solid 4.6GHz using 1.33 volts to the core and 1.26 to the cache ring by using the 125MHz gear ratio and tweaking the bclk up a bit to 127.7 using the 36 multiplier on the core. The cache ring ratio was set lower to allow the memory to run at 3050MHz since core clock speed is supposedly king. For bench marking 4.6GHz on the core, 4342MHz on the Cache ring and 3050MHz on the memory was about my max stable point. Manually tweaking is fun if you have the time, but ASUS gives you the option to use its full auto modes to reach good solid sustainable overclocks to boost system performance. You can use the CPU level up function in the CrashFree BIOS, the EZ Overclocking tool in the EZ mode of the UEFI BIOS, or even using the 5-Way optimization tool in AI Suite III. Using these tools the limit was a 4.4GHz overclock and a memory speed of 2400MHz. Not earth shattering, but doable. If you want to go higher on your CPU and memory, then you can enjoy the BIOS and memory overclocking tools that ASUS has to offer.
