Very low performance GTX 660ti

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

Very low performance GTX 660ti

Postby duke2nukem » Wed Apr 01, 2015 8:47 am

Hey guys ! :)
I've been starting folding now but I noticed that my PPD are significant lower than they should be. With my i5-3570k I get about 4100 PPD and with the GTX 660ti I get 1600 PPD. I read in the forums that the GTX 660ti gets around 60k PPD so I am wondering what I did wrong.
Thanks for your answers !

You have left out the first 100 lines of your log, so all we can do is ask for that. viewtopic.php?f=61&t=26036

Be sure you have a passkey, you will not get a Quick Return Bonus without one. (it will take effect after the 8th successful Work Unit once you enter it)

Mod correction - after 10 WU's processed with passkey active

Without knowing what driver version is installed, the two things I see are that the CPU slot is using 4 cores. This must a setting you changed because 1 core is normally reserved for the GPU slot. If not reserved, the GPU runs slower. Second is that core 18 work units run at about half the PPD as core 17 work units, but nothing you can do about that.

Older card like the 660TI don't fold well with newer driver and vice versa.

When I had my 660TI I used driver until 327.xx. Even 304.xx or 319.xx where ok, and right: that created around 62kPPD (that time on a ubuntu). What version do you use ?
After knowing that we might add some complexity because of Core 18 ;-)

I used to have the driver 347.xx. but the PPD was even a bit less than now, so now I'm running the 327.23. which was suggested in another Forum Thread.

Edit: Running F@H today after 2 hours I now get 36k PPD from my GPU and about 2,5k PPD from my CPU. Still not as many PPD as it should be but a drastic change :D

Actually looks right on target for core 18 with the current version. If you don't get about twice that on the next core 17 work unit, please post that log into.

Okey problem solved I guess, you were right 8-) Reached the next WU today and now I get about 58k PPD with my GPU and 3k with CPU.
