57xx and 58xx locking problems with stripes

That's your hypothesis. My card(5870) won't run stressful 3d titles at it's advertised clocks. However if I clock both the memory and core down 7% it plays everything flawlessly. Is this a driver issue? Unlikely.
More like hardware that does not live up to the hype.

See, thats whats bugging me. Nobody really knows, and the problem is different for everybody. Thats whats so frustrating.
I've tried underclocking my card, core and RAM. It made no difference to me.
(Although I'd be pissed if thats what I had to do, because it's not as advertised).
Maybe this has to do with the low yield issue at TSMC. Maybe they shipped GPU's that they knew where not up to scratch just to meet demand. That would explain why some work, some don't, some work if underclocked, really bad ones still won't work even underclocked.
Im starting to think you may be right HeXploiT, If that turns out to be the case, then ATi's rep is trashed in my eyes.
OK, it's just another theory, but until ATi say something, thats all we have.
