I tried GPU folding in Centos-6, but the FAH log file showed continuous
errors for the GPU (which was, at the time a Nvidia n460GTX). Inquiries
on the FAH forums indicated that there are library incompatibilities 
on Centos-6 and that it would be difficult or impossible to make it

I eventually upgraded to Centos-7 and then easily got GPU folding to
work on the same video card without difficulty.

FYI, I had previously (couple of years ago) attempted GPU folding on 
C6 using a 9800GT, and was told (again, on the FAH forums) that that
GPU was no longer supported. I'd guess that your 9600GT is also too

Here's the FAH forum thread on that GPU compatibility issue:

I've recently replaced the 460GTX with a new 750ti card, and found
two amazing benefits:
1. according to my KillaWatt meter, the computer's power draw dropped from
275-295 watts to 190-195 watts,
2. my PPD total per week has gone from around 200K to more like 400K.
   In fact, the last 3 weeks have all been around 440K, some slightly
   lower, some a little higher.

The 750ti was a fairly cheap card, at $129.

I'm using the Nvidia 340 driver from the elrepo repository. Be sure to
install the dkms package from epel before installing these nvidia drivers.

See above for compatibility comments on this card.
