I've just completed a P67A-UD3 + 2600K build.
It's lovely. Really top drawer, especially with a big cooler like my Coolermaster V6.
Pauleden,
Congrats on your new build! May I ask what BIOS you are using? Did you have any special challenges besides flashing the BIOS? and what speed are you achieving?
Thanks,
Soar
Soar,
Yes, it came with P3, which doesn't support the CPU. I managed to use Qflash to get to P4 where the CPU is supported, then, thanks to advice from Dark Mantis, used @BIOS to get to P6.
He tells me Qflash will work now. I found it didn't work for P5, P6A or P6 - it was reporting bad BIOS image, but it was a bug in qflash, not corrupt BIOS images. As I don't like to routinely flash BIOS, I went straight to P6 using @BIOS and will use qflash for further upgrades if required.
For speed, I assume you mean CPU speed? I'm still at stock.
