Please some help with monero and kepler based cards can't even start the driver crash Windows 8 64 gtx660ti/670 Driver 337.88 I test -d 0,1 and the -l options in the forum.

There's a reg edit for gpu timeout in the bounty thread. Apply it, restart, and you should be good. It crashes because of the 2 sec timeout. This Regedit fixes that. I'm able to now hash at 350-360 on my 780 ti now with it being able to run 6x120 without a crash. Mine would crash with default 8x40 without the Regedit.

Download it, rename to .reg, double click to apply and restart PC. It's fine and doesn't harm anything from what I can see in testing.

~~This old trick doesn't work for any of my kepler cards or rigs which are the 660s with 1152 shaders. I've re-tried it on Windows 8.1, Windows Server 2012 R2 and Windows 7 32. No dice for me.~~

But I'm glad it's working for you!

EDIT: Does work on Windows Server 2012 R2, Windows 8.1 and windows 7 32. My stupid virus/malware programs were blocking/rolling back the reg changes so they never took affect.

With the GTX 660s with 1152 shaders I'm getting about 120 H/s running default settings. Will try playing with settings tomorrow.
