Hi, I recently bought myself an XFX Radeon 5870 for christmas, and at first it was exhilarating. Flawless graphics, every setting on high, the real deal. As of today, for a reason i cannot figure out, the clock speeds are stuck at 157/300, and can only run games at about 9 fps. Regardless of how many times i reset the factory defaults, i get the same results. I reinstalled the CCC in order to get the factory settings, and that did not work either. I have pretty much run out of options but i know that the card is not faulty because i have been using it perfectly for about 5 days now. I have not overclocked, nor have i used overdrive. Cant think of anything else, i dont know what else to do
You might want to go ahead and use overdrive. Just nudge the core clock up 1 notch (5 or 10) and it should work fine. There seems to be some issues with the stock core settings and how it goes into idle mode.
also i forgot to mention, i'm using an EVGA x58 motherboard, which shouldnt be the problem. i read in a few other threads that there were some compatability issues. going to try using older drivers, see if that clears things up
i tried older drivers, using overdrive 1 notch up, and neither had results. Overnight it went from runing RE5 at 60 fps to 9 fps when i try it now. will reinstalling the OS and getting a fresh start maybe help?
update: the core clocks are now running regularly at 850/1200 during gameplay, but i am still getting 9fps!!
reinstalled motherboard drivers as well.
no changes whatsoever.
checked it on gpu-z and everything is running correctly
