Being a mITX motherboard, we'll be checking out the ASRock offering against other mITX motherboards we've looked at lately including the ASRock A75 based one and ASUS H67 based one to see which mITX board can reign supreme.
The question I had to answer first, though, was unlike the other motherboards, could we overclock on this offering? Well, the answer to that one is a simple, Yes!
As we mentioned earlier, the BIOS of the Z68M-ITX HT while offering the normal "OC Tweaker" section, is lacking the ability to adjust the voltage on the CPU side of things; instead it only gives us the ability to play with memory voltage which really isn't any help for us when it comes to the CPU overclocking side of things.
Since we had no voltage to start with, I figured I'd go for a 45x multiplier. We booted, but got a BSOD on the way into Windows. Back to the BIOS and it was time to try a 43x multiplier. While we got into Windows with no problem, as soon as we fired up MediaEspresso which tends to be the most intensive of our benchmarks, we got a BSOD within a few minutes.
Into the BIOS again, we finished with a 41x multiplier which as you can see above resulted in a clock speed of 4090MHz or 4.09GHz as suggested in our graphs.
Compared to other Z68 boards, this is far from the highest overclock we've received. Compared to other mITX boards, though, it's the best overclock we've received. No doubt if you're looking at overclocking on the mITX platform, this is going to be an important factor.
Let's get started!
