ASUS X99 Deluxe Review


ASUS X99 Deluxe Testing:

Testing ASUS' feature rich X99 Deluxe 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.

Testing Setup: Intel Socket 2011 V-3

Overclocked settings:


There are more than a few ways to get the most from your CPU using the X99 Deluxe. For the enthusiast, you can manually tune the BIOS in any number of ways. 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. Second, you can use ASUS' 5-Way optimization tool for a truly one touch overclock. Start the tool and sit back and watch as it gives you a solid stable overclock. About as simple as you can get. Additionally, you can use the auto-overclocking tools in the BIOS in either the EZ or Advanced sections of the BIOS.

Manually tuning the parameters to get my Core i7 5960X to 4.6GHz was fairly simple. I set the XMP profile for the memory and adjusted the clock multiplier to reach 4.6GHz. You really do not need to tune the voltage with how good ASUS' auto rules are, but to get the lowest possible voltage, you need to manage it manually. Overclocking is no harder than massaging a Core i7 4790K on a Z97 board. One thing to note is that setting an XMP profile higher than 2400MHz causes the board to default the bclk to a125MHz gear ratio and reduces the clock multiplier accordingly. If your memory controller is strong enough, you can flip back to a 100MHz gear ratio and start inching the clocks up.

Overall, there were no real issues when overclocking the board. The installed hardware limits are your limiting factors with this board. After my fully stable overclocking, I had to have some OC play time using a liquid cooling system and some less than stable testing for screen caps just to see what the board could do with even more voltage. The highest speed I could run any lightweight benches was 4.9+GHz on the CPU and 3200+MHz on the 2800MHz-rated memory modules. Anything higher resulted in BSODs. If you want to overclock, the X99 Deluxe is not a board you should shy away from.
