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.
We've got a bunch of motherboards in our graphs here today, with the GIGBAYTE Z87X-OC Force being run at both stock speed, and overclocked. We'll talk about the latter in just a moment. As for the other boards that you'll see in our graphs today, we've got the MSI Z87-GD65 GAMING, ASRock Z87 OC FORMULA, and the non-Force version of the board we're looking at today: the GIGABYTE Z87X-OC.
Along with all those Z87 based options, we've also got the Z77 based MSI Z77A-GD65 Gaming, alongside the GIGABYTE X79S-UP5-Wi-Fi to round things off. As always though, before we get into the performance of the board, we need to check what exactly is going on in terms of the overclock.
Overclocking went really well on the board, and it looked like we might be able to get 5GHz stable. We didn't have any problems getting into Windows, and it survived much longer than other boards we've tested. We messed around with the voltages for ages, in all places, to see if we could get it stable. In the end though, no matter what, that 50x multiplier just didn't want to play nice.
We moved back to the 49x multiplier, which brings us in at 4.9GHz. This is the number that we find most of our boards sitting at. It came as no surprise that this was stable, so we headed back into the BIOS to mess with the BCLK a little, to see if we could get any more. Unfortunately, we couldn't get anything stable.
In the end though, we got 4.9GHz stable, which is a strong overclock. We did manage to drop the voltage down, and had the system stable at 1.323v. We're hoping this will mean that at this speed, we won't experience high 90c load numbers when it comes to the temperature.
