Howdy, I'm fairly new to this overclocking business as evidenced by my first post which was long and didn't get read much.

I have a problem though. Just now running 3Mark Vantage, twice, and a few times last night playing TrackMania Nations I've had system crashes; but when it restarts the only notification I get from Windows is a safe mode option, no crash analysis or anything so I'm wondering if you guys can help me narrow it down and work out how to stop it!

It seems to happen when my graphics card has to swap to 3D rendering time. I'm running a 4870x2 and I've played through the whole of Crysis Warhead on it though with no problems, so am somewhat confused.

Every time it's happened so far it's been as a loading period finishes but before anything is actually rendered; it seems like it tries. fails and crashes.

Any thoughts/tests etc you could suggest to a newbie?
 
Prime 95 for testing your CPU and your RAm, you need to run it on the small fft option first and then on blend. Will take a while though about 8 hours each test to guarantee its stable. Did you OC your graphics card?

I've run it on both small FFTs and blend for about 8 hours each with no errors being thrown up. Should I try running them again for longer? Was under the impression that 8 odd hours should be long enough to throw up any errors.

I tried to OC by graphics card but it really didn't seem to like it. I was going to ask for advice on that separately, but for the moment I think it's CCC defaults again. 507/500 idle and 750/900 load.

Does it seem like it could be a RAM issue then? Or could it be literally any of the 3?
 
Prime 95 Blend Test should have found any problems with your RAM, 8 hours should be plenty. Try downloading Memtest and give that a go just to be sure. I have the same graphics card and i tried to overclock it by the tiniest of amounts and it threw a wobbly and crashed so best to keep that standard. Sorry i cant be of more help, best just to keep testing mate.
 
I've had prime fail after 15 hours, so i guess 'stable' is subjective - i guess it's what your happy with, the longer the better. Personally if it gets to 24 hours stable on all cores i doubt you'll have much trouble from it.
 
Give it 24 hours for a real test.

Now when you say crashes does it restart or hang?

Go into control panel then system, click on advanced system testing then on start up and recovery.

Now see that tick box that says "automatically restart."
Make sure it is unticked.

Now if your system suffers from a blue screen error next time it crashes you'll get to see if for yourself.

It was restarting and that box was ticked, so thank you! I didn't even know that option existed; I've unticked it and next time it happens I'll post the error message here :)
