need some guide here for a newbie, I'm currently using 2500k+GA-P67A-UD3, previously OC to 4Ghz using stock heatsink. But recently I just brought CM V6GT and try to overclock it to 4.5Ghz, Vcore at 1.35. Supposedly working fine, but after few hours of gaming, it would crash into bluescreen, dumping memory something like that, seem like it still not stable .... any advise I could use ?

0x124 = increase/decrease QPI/VTT first, if not increase/decrease vcore...have to test to see which one it is
My vcore already bump to 1.35 instead of 1.34, still having the same issue, but the length of "survivability" was longer ..... still need to increase ??

I'm running daily i5 2500k 4.5Ghz at around 1.38V for stable =.=
I think my voltage too high .... but if decrease will having bdos 12~24 hours late .... how to improve it >.<

ok, will disable it and try again tonight ^^ thanks for the tips !
