I suppose it should be of no surprise to me personally that I have bought yet another factory OC card that doesn't really work at factory OC levels.... I am, however, surprised at my own stupidity!
Initially (tonight) the card worked perfectly at 835/2100. I tried Kombustor which worked with no issues. Then the Heaven benchmark... no problems. Then I loaded up Just Cause 2 and ran the benchmarks:
Dark Tower (worked fine)
The desert one (worked fine)
Finally I ran "Concrete Jungle".
System locked up completely. I thought it might be a fluke but after rebooting about 5 times because Concete Jungle had locked at another random point I decided to downclock to reference settings and haven't had a lock in concrete jungle since.
I guess I'm just pleased I spotted this now rather than later. Over the years I've had numerous factory "OC" cards and sooner or later some game or other has caused them to lock up. I've also seen many forum posts from people with OC cards complaining that only "this" game crashes the graphics card... and therefore it's the game pushing the card too much... No it's just a bog standard card with an "OC" sticker and a higher clock setting in the BIOS!
I guess I should have learned my lesson before now!
I might return the card to Overclockers but it wasn't much more expensive than the standard card and just might be a bit more reliable at stock speeds... I very much doubt any replacement will be any better without a huge amount of luck!
I might have a try at upping the voltage a bit... It's set at stock which is a bit of a surprise.
I do like the 580 though. Very, very quiet and seems to run a lot cooler than the 480.
