I am new here, first post but I have been following this thread since the beginning and used much of the advice here to overclock my Z68 Extreme, i2500K. Lately I have been having BSOD issues and have now fitured out it was error 124 which apparently means "0x124 = add/remove vcore or QPI/VTT voltage (usually Vcore, once it was QPI/VTT)". The problem is that I am very new to this and have no idea what to tweak next. Screenshot of my setting attached. Note that I started at 4.9 and then reduced to 4.8 and 4.7 still with the problem.

Probably should mention that I have BIOS 1.70 installed.
