so today I was at a lan and a guy gave me his old 7870 which he sayed had issues with artifacting.
I ran fur mark and it ran, the card overheated and it crashed. I just replaced the thermal paste with some halziye stuff. it is >3.05w/m-k
same issue, card gets hot and it crashes. all voltages are at stock with stock clocks and for reference it is the saphire overclocked eddition. fans are at 90 to 100 percent...
any ideas???
note: if I drop the clocks right back to like 800 core, 800 mem it works fine and passed a 20 min stress test
