I was trying to overclock my Core i5-3570K Ivy Bridge on Gigabyte P67A-UD4-B3 but while doing so i found that it has locked core. The multiplier itself is limited to x38 and there is no way I can go above that. Also I don’t think without leaving that point the processor will be able to overclock near to 4GHZ.
I thought that it should be unlocked processor since it has “K” letter at the end and the K family processor always comes with unlocked multiplier. I am not sure whether the multiplier is limited on the processor side or the motherboard side.
If it is the limitation of motherboard, can anyone tell me what Gigabyte is doing here?
