Hello all,

I have been mining for about a month with an overclocked 5870 at 900MHz and memory at 1300MHz (Base speed is 850MHz and 1200MHz) and my hashrate was always around 330MHash/s

Last night as I was playing starcraft 2 my whole computer froze and I was forced to turn it off then on again.  When I ran my miner again with the overclock my hashrate is reduced to 323Mhash/s on average.  The difference is not extreme but I'm afraid that I have damaged my card.  Is there a way to confirm damage done to a card?  Any thoughts?  Btw my miner is poclbm_py2exe_20110311

I had similar occurrences, also on a 5870 (and Windows XP). The most recent was that I left my miner (poclbm GUI) running, and when I checked it some hours later the hashrate was 140 MH/s. Restarting the OS restored the normal hashing rate of 315 MH/s. Any ideas about the cause of this?

Yeah this has also happened to me, however this time, the hashrate never restored itself to its previous level of performance.

This might be a case for a dedicated rig.

Nah not really worth the investment considering I only have one 5870, i might just turn off my miner or remove the overclock when I play games.  Dunno tho.

Maybe this is PSU related problem.
What PSU do you have?

Can you measure +12V voltage with multimeter (under load & idle)?

Have you got any *.elf files in the poclbm directory? If so, delete them and try starting the miner again.
