Overclocking gone wrong, please advise........

Hi,

I have a Gigabyte GA-P31-DS3L with a e2160 and a freezer pro 7. I had it running happily at 3ghz no problem atall. I decided to up the FSB to 350 (hardly a huge OC and this board can easily handle it) and see how the temps are and it just switched off before posting. So i reverted back to 3ghz and it loaded to windows, played the tune and then froze with the screen showing grey, blue and black diagnol blocky lines.

So I restored factory defaults (1.8ghz) and loaded to windows and it did the same thing.

I assumed my overclock corrupted windows so I reformated and all was fine at stock settings so I clocked it back up to my longtime stable 3ghz (333x9) and it did the same thing, freezed up with diagnol lines. Then again at stock settings.

Any ideas what has happened, am I gonna have to constantly reformat in order to find a OC that doesn't mess up windows.

Ive cleared the cmos, done a disk check and its still the same. Gonna try a reflash, if this doesn't sort it out, any ideas?

Cheers

Well sounds like your chip/mobo/ram/video card is not actually as stable as you thought they were at 3Ghz+ You'll have to restart at stock and slowly work your way up the (over)clock scale, testing and re-testing the overclock with Orthos/Prime and MemTest for memory (together with whatever else you can throw at it to hammer it.) A borderline instability usually shouldn't corrupt your windows install but there's never a guarantee. Do each part in isolation, so when clocking your cpu keep your RAM at or under stock, and vice versa.

Hi

Thanks for reply, I had my 3ghz very stable been running it for a while with no failure and i ran orthos for a long period. Its when I went to high is caused *** problems but even when you drop it down to stock i still have the issue so it must be corrupting windows. I'll take you advice and start working my way up cheers.

Think I have caused permanant damage?

cheers

Possible but fairly unlikely. I'd actually suggest you reseat/reapply the heatsink as well, and the memory dimm's. Make sure the video card is not overheating/having throwing some spanner in the works.

Thanks

will try them, its not the vid card overheating im at around 75C on my 7950 gx2 full load so that ok, I have a funny feeling ntune (i hope) is my problem. This happened after I installed ntune and this happen again when I reinstalled and installed ntune rigth away again.

soon find out

edit: RESULT! was nTune all along, I was warned this program messed up your system, running at 3ghz quite nicely now.

cheers for help anyways

nTune + 7950GX2 doesn't seem to work well sometimes - I was constantly getting BSOD with it - which went away when I relegated the board to my media PC with an 8500GT...
