I recently started running this project - GPU Folding - to help the team as my Nvidia cards (GeForce 8 series) no longer cut the mustard for BOINC-based CUDA projects like SETI and Milkyway. My CPUs are busy with BOINC but the graphics cards were not doing anything.
They run fine and painlessly under Folding@Home, temps are not excessive, load on the CPU is not much so BOINC is also unaffected. If like me you have these older cards and would like to help the team, why not pop over to the Folding sub-forum and follow the guide there to set them up?
I also managed to get my 5770 folding as well, but the performance level compared to the nvidia cards was such that I sold the card on. All point count though, so yes they will help
Hmm… someone remind me to look into this when I get home. Got a 9500GT idle at moment. Did run it a little under boinc but it wasn’t out-performing a CPU core so I just disabled it. If it can be run outside boinc I’ll give it another go…
