Test System Setup and Overclocking




We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: Intel, ASUS, MSI, Western Digital, MemoRight, and Corsair.


Sitting alongside our ASRock X99 OC Formula motherboard, which we'll be running at both stock and overclocked, we've got a number of other options. Our other options today include the MSI X99S GAMING 9 AC, ASUS ROG Rampage V Extreme, ASUS X99 Deluxe, and GIAGBYTE X99 UD5-WIFI to round out the X99 options, which are all using the Intel i7 5960X EE CPU.


Along with those, we also have the ASRock Z97X Killer, and ASUS ROG MAXIMUS VII FORMULA, which are Z97 based boards using the much more budget friendly i7 4790K CPU. As always, before we get into the performance of our board today, we need to take a quick look at what's going on with the board as far as overclocking is concerned.


To overclock today, I opted to use the 4.5GHz profile, which gives us a really good start as far as clock speeds go. More importantly, this is a good area for the voltages to be at. Since I knew this clock speed wouldn't be an issue, I increased the multiplier even higher.




In the end, after messing around for a while, the multiplier was stable at 47x, which gives us a 4.7GHz core clock with the base 100 BCLK. Along with this, we managed to get a tiny boost out of the BCLK, which came in at 100.26. This, in turn, boosted the CPU clock even higher, with the final clock speed coming in at 4712MHz, or 4.712GHz as shown in our graphs today. This is one of the highest clocks we've seen to date, if not slightly higher by a few MHz.
