What about your graphic card?? Is it stable??

You can just drop CPU multiplier to 6x so your system would run at 435 x 6 = 2.6GHz..

That way when you play BC2 if your system freezes again you can rule out Vcore as being one to blame..

As your CPU would run only at 2.6GHz and even a stock Vcore would be more than enough..

But if it freezes again at 435 x 6 = 2.6GHz then Vcore is not what makes your 3.9GHz OC unstable as it would be caused by something else..

CHEERS..

how can i see if the graphic card is stable? it's using stock clocks, it's kinda strange because when i added more vcore yesterday till 1.39 it worked fine last night with bc2 and league of legends, now it's freezing on bc2 -.- what else could be te problem causing it? going to put it on 2.6ghz and drop vcore to auto or 1.3?

Set your system (CPU and everything) to stock and run some games..

If it doesn't crash then your graphic card is OK

Set Vcore to 1.3V and set your CPU multi to 6x,everything else leave as it was at 3.9GHz..

If it crashes again then it's not Vcore issue..

Then look at RAM..

Lockups, freezes or reboots without a blue screen sound like Mobo/RAM related. Follow ^^ his advice about testing at x6 first. I think my E8400 needed 1.36-1.37 actual vcore in CPU-Z to run at 4.005Ghz. That was like 1.41 in BIOS, my Gigabyte DS3R has horribly voltage loss.

You do realize that you may have to play around with not only Vcore, but Vtt, SB, NB voltages as well. I think your Vcore is just getting way too high. You should be find at 1.3V Vcore or slightly higher to get a 4Ghz overclock in that processor. Is your RAM unlinked and running at 800 Mhz? Also, is RAM timing set to what manufacture suggested as well as RAM voltage? First thing to do honestly is to set your RAM stuff and just overclock with everything in auto.

ram is running at 871mhz atm, and it as 2.00v in it the stock is 1.8 and cas is at stock too, still playing BC 2 without any freezes or reboot's, ok i'm gonna try to put the FSB at 435 with everything on auto only ram stays as it is
