I have exact the same problem with my EVGA 260/216.
Downclocks from 626MHz to 400MHz and stays there until I reboot. It doesn't happen every time I play games tho. BIOS version is 62.00.1A.00.19

go to the NVCP and then 3d settings, look for the power management tab and select "Prefer Max Performance"

my 260 used to downclock while gaming before i set it to "Prefer Max Performance" and the bonus is that it will still drop clocks in 2d mode

Prefer Max Performance didn't help but removing and cleaning drivers with the DriverSweeper from the safe mode works for now. Also, I've reinstalled 195.62 drivers from the safe mode.

Update your drivers

I have had the same issue with my 285 dropping down to 2d clocks due to a bug in the drivers, I think the newest ones fixed that

I have tried all of the above and it still happens now and then. It has nothing to do with temps which remain below 65 in my rig. I wish nVidia would introduce the option of disabling power saving.
