I managed to kill the processor I was running on my extreme4 on friday. I had been running a i5-2500k overclocked to 4GHz and I think that after a week of compressing video files it finally overcooked and died - system no longer boots and Dr debug shows 23, the only reference to which I found via google indicates a dead processor. the blocked processor heatsink almost certainly didn't help.
So, I need a new chip and am looking at the ivybridge equivelent to what I had (i5-3570k), which has been supported since BIOS 3.1. Only problem is I can't remember whether I flashed to the lastet BIOS or not before my i5-2500k died.
So, my question is, if I install the ivybridge i5-3570k and I am running an older BIOS, will I be able to boot to the UEFI to flash the BIOS ? Or am I limited to the sandybridge architecture until I flash ?
