I recently upgraded my graphics card from a gtx 275 to a gigabyte gtx 560 sc. after a few days the screen started to black out and says it has recovered from a driver crash. From there i did clean installs of older drivers to see if it would fix that. using 275.33 fixed that for the most part but then in game (skyrim+wow) the card would auto downclock to 405MHz and wont go back up to default or factory stock speed until system restart. also sometimes it would studder then reset the clock speed i set using afterburner(822) back to 900. running benchmarks doesn't do any of this and it doesn't seem to be a temperature issue. ive also updated my bios, swap out to my gtx 275 using both old and new driver and different slots. old card works fine in both slots and drivers. and used memtest on all my ram sticks and removed any that were questionable. wow+skyrim=crash but benchmark+swtor doesnt.

If I understand correctly, you over clocked the card? I would suggest you undo that and set it back to stock settings and see if it's ok. Overclocking can cause a variety of issues, I know fluctuating clocks are one of them.

900mhz is the factory stock settings i tried to keep it at 822mhz which is nvidia's default setting but even doing that it would auto downclock to 405 while in game or sometimes auto back to 900 before crashing.

and no i havent tried to update the bios on the card itself, i just bought it so didnt think it would be a problem but ill try that now
 
The different clocks are there for idle states, are you sure they're changing in game or are they just dropping when you alt tab to see how everything is doing?

vBIOS flashing might be the key here. If not you should contact the manufacturer or retailer and see about a replacement.

i had multi screen up when i was tracking the clocks and i would also feel the change in game when it happens. I also closed the game and started a benchmark to see if it would kick out of idle mode but it didnt unless there was a reboot.

I seem to be having a very hard time trying to find a bios for my card and only drivers off the gigabyte site. really was hoping getting a replacement would be the last resort.

yes updated the motherboard bios and chipsets last night and this morning. and right now with gtx560 in and nvidia's 290.53 driver im crashing after about 5-10 mins of gameplay with a blue screen. gtx 275 worked fine with this driver and same MB slot tho.

Same problem happened to me. I have same gfx,but Zotac brand, OC to 940-core/2080-mem, stock voltage 1.0370V (stable in Crysis, Crysis 2, Metro 2033, BF3), and downclocking memory to 2060 mhz fix the problem. Playing Skyrim without crash about 20 days now. :D
