Overclocking Results

In this section, I will go through overclocking this board.

CPU Overclocking

Max CPU Overclock is found by setting the VCore to 1.5v, Input voltage to 2.1v, cache voltage to 1.15v, booting with a CPU multiplier of 45x and disabling any features that would result in CPU frequency fluctuation. I then proceed into Windows and use software to increase the multiplier; in this case I opted to use GTL.


5.0GHz is the maximum of our CPU on this board and other X99 motherboards. It is clear that CPU overclocking is pretty good for high frequency. Maximum AIDA64 Stable Overclock (BIOS settings below for this):

I was easily able to pull off 4.5GHz on the CPU with 3.2GHz cache and a 2133MHz overclock on my memory manually tuning the UEFI.

Uncore/Cache Overclocking

Boards with the extra pins in the socket can overclock the cache further, on the X99-SLI I was able to OC the cache to 4.3GHz, while the core was 4.5GHz.

Memory Overclocking

This section is a new addition. Corsair was nice enough to provide a 3200MHz quad-channel DDR4 kit for our benchmarks, and I decided to see how easy it is to boot with their XMP profile on different motherboards. In the early days of X99 trying to boot with the 32x memory multiplier was a nightmare, some boards did it with a lot of training (loops on startup), and some didn't even have the option. At this point in time I decided to test out how easy it is to use on each board.

The X99-SLI handed this kit with ease and when I loaded XMP it set the 32x multiplier from the get-go. I was able to boot into Windows and there was no noticeable memory training upon the first boot. I then restarted from Windows and had no issue with memory training again. I then shut the computer down, waited 5 minutes and powered up, the board performed perfectly.
