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.
Looking above, you can see our standard testbed setup. Everything is really covered in the above image, so we'll get stuck into what boards you're going to be seeing in our graphs today. Alongside our GIGABYTE Z87X-UD5TH, which we'll be running at both stock and overclocked, we've got a number of other boards included in our graphs today.
Also on the Z87 side of things, we've got the MSI Z87-GD65 GAMING, the ASRock Z87 OC FORMULA, and the GIGABYTE Z87X-OC Force to round things off. Also included are the MSI Z77A-GD65 GAMING, and the GIGABYTE X79S-UP5-WIFI to help round off the collection of motherboards that we have on hand.
Before we get into the performance side of things, we need to take the time to quickly look at what happened when it came to the overclocking side of things. With the latest BIOS installed, we head into the BIOS and start messing around with our Multiplier. As always, we moved to a 50x Multiplier, in the hopes that we're able to get 5GHz stable.
Like we often see, the board got into Windows okay, but it didn't do much more than that. We started a Media Espresso encode, but found ourselves with the system quickly getting a BSOD. Not really surprised, we headed back into the BIOS and adjusted our voltages a bit, in the hopes of maybe get 5GHz stable. A bit of time, and a bunch of reboots later, we find ourselves looking at BSOD over BSOD.
With 5GHz not happening, we headed back into the BIOS, and moved to a 49x Multiplier. As we expected, we didn't run into any problems here. With that working fine, we headed into the BIOS again to see if we can do any fine tuning. Maybe bump the BLCK slightly, or change the voltages.
However, the BCLK didn't want to go anywhere, so we instead took the time to drop the voltages to see what we needed to get our CPU stable. In the end, as you can see above, we have our CPU running at 4.9GHz as illustrated in our graphs today, with the core voltage being 1.318v.
As usual, this is a very standard overclock for us. It seems to be the best our CPU is capable of most of the time. Every once and a while, we're able to get maybe an extra few MHz thanks to a slightly adjustment in the BCLK, but 4.9GHz represents the number we most often see when it comes to overclocking.
