Brand new ati hd5770 - crashing already!!

[adam1516]

Hi guys,

OK, installed my new card yesterday - sapphire 5770 1gb - and since then, EVERY game I have played has crashed. Some have crashed after a few minutes, some after an hour.

Split Second crashed to blue screen, even a crappy game like spellforce 2 crashes after an hour - to a blank black screen. Latest drivers are of course installed.


O/S is win7 64. Just one note - the cpu is overclocked - could that have an effect on the card? The cpu temp is only 38C thanks to the freezer fan I have installed.

Any advice appreciated.

Can you either try a different graphics card in your machine, or try the 5770 in a different machine? if not try using stock settings for your motherboard, crashing could be due to overclocked RAM.

Are you sure your PSU is upto the job?

Try 20 passes of IBT to see if the rest of the PC is stable.

TBH I've seen quite a bit of this with the ATI 5 series - the 5770 especially - having built a few PCs to spec for friends - some people have had joy after 1-2 RMA jobs others have given up and gone nVidia - as I've installed these systems from scratch with a fresh OS I can't really blame user error.

EDIT: As above you need to test the base PC and GPU individually if possible to try and narrow down whats causing it.

Have you plugged in the 6 pin PCIe power connection from the PSU into the graphics card?

Next question, is the CPU stable under load? You can check this with a programme like OCCT if you haven't already.

If the CPU is fine, I would suggest putting the GPU under some stress using Furmark and see how it fares.

1. What PSU you using?
2. What temps the card running at?
3. Did you clean the nvidia drivers out?

Yea sounds like could be an unstable overclock, needs to pass 8 hours orthos/prime95 and at least 20 runs of IBT.

adam1516, what graphics card did you have before (if any?) and was the overclocked PC stable etc?

What is your system specs? (CPU/Mem/Mobo/PSU) and tell us more details about the overclock . . .

As has already been suggested above it is standard trouble-shooting proceedure to reset a system back to stock if experiencing problems, if you do this and everything works fine again and your games stop crashing then you can be fairly confident the problem lay with the overclock and not some driver mismash etc . . .

Once you know this for sure we can maybe help you get the overclock stable if that's whats causing the problem!

Good luck!

what drivers are you using, not 10.6 by any chance?

10.6 seems fairly stable by and large with single card setups but crossfire is a differant matter. I just hope he isn't using the driver disc that came in the box.

I would just agree with what others have said, stress test your system with IBT and Furmark or ATi Tools Artifact scanner at the same time, set your PC back to stock settings.
