I've made a few topics on this before, but I've never been able to get it sorted.

I have a new graphics card, MSI 6850 cyclone edition OC and it crashes a lot when I try to run games, usually when the game is loading. I RMA'd it after I'd done pretty much everything I could I.e. update bios, reinstal windows, installing the drivers cleanly etc... and they said it's not faulty, but the problem persisted.

I tried underclocking my card from about 860|1100 to 600|1000 and it seems much more stable now and I can almost always run my games without it crashing.

But I shouldn't have to underclock it from the default factory settings. Does anyone have any advice on why I'm having to do this? I have a 650w corsair PSU, 6GB ram corsair, i7 920 @ 2.67Ghz processor (was 3.4Ghz but clocking it back to default was one of my attempts to fix the problem) and a Gigabyte EX58-UD3R motherboard.

One other thing is that in GPU-Z in the VDDC sensor it always says I have 0.00V, could it be a power problem?
 
As I put in the post, it's a 650w corsair PSU. Never had any problems with anything else. could it be that it's not recieving any power from the 6 pin power cable? I've tried both of the spare ones though and the problem is the same one both.

Overclockers said it wasn't faulty when I RMA'd it, they said it passed all benchmark tests. I don't think they tried it on any games though...
 
I just tried running it on a few different clocks

860 core | 1100 Memory = crashes (default)
800 core | 1100 Memory = crashes
750 core | 1100 Memory = crashes
700 core | 1000 Memory = fine
600 core | 1000 Memory = fine

for some reason the card can't clock to anywhere near the default settings, it crashes even at 750 which is 110MHz below the factory settings.

What should I do? Increase the voltage with Afterburner and see if that makes things better?
 
I turned the computer on this morning and green and purple lines are going along the bottom of my screen!

Help... I don't know what to do, it looks like a faulty card, but RMA said it's not!

it has to be the card then!

what else can it be, if another card is running perfectly and you have uninstalled, reinstalled the latest drivers etc...

it has to be the card!
 
anyway u can try it someone elses machine?

edit:agree with cinderzftw, but if one side is saying it's faulty and the other saying its not, then whare does it end?

only other option would be to send it back for a different brand of card.

thanks opstrat.

it is a hard one this thread... we say broke... manufacturer says not..

could get a different model if needed.
 
Yea, I'd like to try it on another machine, but that's easier said than done. I don't have access to other desktops here, everyone else has laptops. But I should be able to find a way.

How thorough are the RMA checks? Could it be that it is faulty but they didn't find it?

When I restarted the pc after I had those lines It came back with the same lines and then crashed after about 20 seconds. I've put my old card in now as I have to do some work and it's working completely fine...

Edit: would OCUK be willing to provide me with a different model do you think?

Edit: by the way, I RMA'd it with OCUK not the manufacturer MSI

They review the cards pretty thoroughly I would expect. Test the cards under a lot of stress tests etc.

It could be faulty and they may not have found it.

Record what happens when you have the card in i.e. camera or video recorder, take images of the screen, screen dumps etc to prove what keeps happening.

All you can really do to support the claim that the card is screwed!
 
yea i recently bought a 9800gt from ebay and it artefacts like a *****!

had to take images to proof the card was in the machine and prove that the card was artefacting...

the seller said keep the card and ill give you a refund...

decided to bake the card, now working and a refund xD LOVE IT!
 
I fear baking it would void my warranty! :D But if I never get it sorted I might try it, just for the laugh if nothing else, would love to say I fixed my graphics card by literally whacking it in an oven xD
 
I increased the voltage from 1149mV to 1200mV and it seems to be much more stable at the moment. The MSI cyclone OC runs at 860 core and 1100 memory at default. That is very high compared to most HD 6850 cards. Could it be that the default 1149mV voltage it runs at wasn't enough for some reason as it seemed stable when I underclocked it to ~700 core and ~1000 memory when using the default voltage which is nearer (but nevertheless a fair bit under, most seem to run at 775 core and 1000 memory) what most HD 6850 cards seem to run at...
