Looking at the testbed side of things, as usual there's nothing out of the ordinary, so let's just get into the overclocking side of things to see how our beloved 2600k went on the Z68 Extreme4 Gen3 today.
Getting into the BIOS and firing up OC Tweaker, we messed around with our voltages and multiplier a little to see what we could get out of the system. At 50x we couldn't get the board to boot, while moving to 48x we could get our system to boot, but BSOD on Windows entry. Moving to 47x got us in Windows, but as soon as we started to do anything intensive, we'd be greeted by that BSOD again.
As you can see above, we in the end landed on a 46x multiplier which with the BCLK at 100.54 resulted in a final CPU clock of 4624MHz or 4.62GHz as illustrated in our graphs.
This is a fairly standard area for the mid-range ASRock boards. We saw the Extreme7 go a bit over 5GHz; you can see our Extreme4 came in a bit lower today, though. Still, it's a nice overclock from the default 3.4GHz and should hopefully yield some good performance.
Let's get started!
