5970- boots, but won't mine

[Dervana]

I picked up a second hand 5970 and having installed it I've found that it fails to mine...

The PSU is fine (850W /w 70A on 12 rail) and I've tested it in three systems now, all displaying the same issue- Using the 50BTC GUI program I attempt to fire it into mining mode and it sits for a while before declaring 'connection error' (or similar equivalent). CGMiner also sits for a moment before crashing. All three systems are fine mining with other cards. I know it's not a settings issue as 50BTC autosets itself to the card at hand and with CGMiner I use recommended settings.

Does this sound like the card itself may be screwed? It boots windows fine without any glitches, just fails to perform once I try to mine with it.

Are you using it as the display card? If so run furmark and see if it passes. http://www.ozone3d.net/benchmarks/fur/
