So I dusted of an old 7970 a few weeks ago to mine some ZEC at Nicehash.  Been steady at 275 kh/s for about 6 weeks with 0 rejects.  I come home from work a few nights ago to see the miner is down.  Initially I figure no biggie, boot her up and start mining.  It didn't boot right away and it wouldn't boot up until I switch to the second bios on the gpu (dual bios mode card).

With the bios switched the clocks go back to default and I start mining again except that now I am getting a TON of rejects, somewhere around 30% rejects. 

Now I can run the miner with either bios again and I can OC the gpu or run it at stock clock settings and I still get 30% or so reject rate.

GPU is on the mobo and not on a riser

Is it time to retire the old gal?  I mean it's not like she owe's me anything.  She's paid herself off a few times over but I can't justify running it at 30% less hashrate Sad

Try to wipe the drivers with DDU, should get her back in the business.
