I was told that current GPU software required a Nividia Fermi or later GPU, which leaves out the entire 9xxx series. See http://nouveau.freedesktop.org/wiki/CodeNames/ Re upgrading to C7, I can see how you may be nervous about that, given the number of things changed. I just upgraded my personal desktop during Christmas week, seeing as how I never rush into upgrading to a new version until it has had time to "settle". There are a lot of differences, but i'm learning to deal with them. When my old system gets old enough that a lot of newer stuff will no longer build, then it's time for me to do the deed. then all I have to do is steel myself up for a week of putting it all back together. :) good luck, Mark!

It should be compatible but I guess it won't work on C6 though.

Do any of you have a GPU that is actually > folding in CentOS 6? 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 work. 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 old. Here's the FAH forum thread on that GPU compatibility issue: https://foldingforum.org/viewtopic.php?f=80&t=25284&p=252427&hilit=9800GT#p252427 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. > If you do please tell me exactly what video card and what driver you are > using? I'm using the Nvidia 340 driver from the elrepo repository.
