Crashing heaven 3.0?

Im having a little issue with Heaven 3.0 crashing after about 10 minutes. reporting that the display driver had to be restarted. I was watching it run and the temperature never went above 72c and there was no artifacting.

I also had Saints Row the third crash today with me today just with a not responding error which has never happened before.

I ran heaven for well over an hour last week with no issues I was also playing saints row earlier in the week for around 3 hours non stop.

The only change ive made since then is ive changed my cpu cooler but its definately not overheating.

Ive done IBT on maximum for 10 passes and run prime for 18 hours again without issue.



My PC spec is below

i5 2500k @4.5ghz
8GB Samsung green
Asrock Z77 Extreme 4

SLI GTX470 @800mhz core and stock mem 1.025v
1x GTX 470 MSI twin Frozr II
1x GTX470 Gainward Good edition

XFX PRO850W Core Edition PSU.

Now when i run my cards at stock clocks/volts the fault goes away but wheres the fun in that?

The cards appear to perform faultlessly right up until the point they I get the crash. Im wondering if this could be a power issue? Surely my 850w PSU should be enough to power this set up unless its on its way out?

Can anyone offer advice on this?
Thanks
Scott

You might need more core volts on the GPU's, iirc GTX480 was 700mhz @1063mV... 800mhz @1025mV looks low to me.

I did my overclock on these cards a couple of weeks ago when i got them and pushed it as far as i could at stock volts (Think i got 775). Then upped the voltage until I could achieve 800 core stabily without crashing or artifacting.

I did push them up to 1.030 hardly a big jump i know but it didnt improve things.

I have heard that cards deteriorate/require more volts as they get older but I wouldnt expect the results to change in a week.

Ill try 1.050v and see what happens as i believe the "safe" limit is 1.087v
 
The odd thing for me is that these are the same drivers i was using before when it was working fine.

Ive tried 1.050 and it froze rather than crashed this time :)
 
Ahh thats beta!

The new beta drivers fixed it. Maybe re installing the old drivers would have done the same as something must have gotten screwed up with them thanks for the help guys.

I think thats one of the least helpful posts ever.

To be fair your post wasn't particularly well articulated. If you crank up your overclock too high then you will get crashes. It might not be immediately or even in every game or benchmark but the result is the same - it might seem stable but it's not. The best rule of thumb is to push to the max then keep dropping your overclock until everything is stable... then drop it a bit more for safety. I've had plenty of occasions where 3DMark11 and Heaven 3 are 100% stable, yet a random game will cause the driver to stop responding. You may think those few extra MHz are critical but a stable system is much more important.

If your overclock is right on the edge then even a slightly hotter day can trigger a crash.

I mentioned temps and the fact id run all the programmes before can you please tell me what else i could have said to clarify or as you put it articulate the issue i was having?

Im 100% with you on the stability thing and i always do a lot of stress testing to determine whether an overclock is stable.

A one liner telling me my overclock is too high is not helpful and to me smacks of someone trying to get their post count up.
