Earlier I made a post about it and thought the problem was fixed, I had to underclock the card to get it to work but then after I set the power to 20% in CCC I didnt have to any longer. That worked at first but after I downloaded 3Dmark and got to Fire Strike it crashed again and now even with the power at 20% the games are crashing again. I have tried reintalling the drivers and CCC again but it continues to crash now its even crashing when I underclock it.

try just bringing things back to stock,

NO CPU overclock, RAM @ stock (even try going back to 4gb as it doesn’t make much diff for 3d mark)
can you get access to a larger PSU? it could be running into problems with lack of power, as PSU's lose their efficiency the older they are

I formatted a hard drive, put everything at stock took out 2 sticks of memory and it still casues the pc to freeze/crash. I can get a new psu in a few days I guess if that could be the problem. I will have had my current PSU for 3 years in January. I did get it working underclocked again atleast.

wish I could RMA waited too long and i've tried contacting sapphire about it for over a week and they haven't replied to any of my emails. Something I just noticed, I underclocked the memory clock from 1250 to1200 and raised GPU clock from 800 underclock to 900 overclock and it didnt crash. I think it has something to do with the memory speed.

it's still under warranty I just got it less than 2 months ago I just cant get them to replied to me and i've sent a few emails over the past week or more. I tried it again I left the mem clock at 1200 and put GPU clock at 1000 and no crash. I'm going to re download 3dmark and try it again bc that's where it messed up last time but when I ran it then the mem clock was 1250.
