Threw these 4 cards together for energy savings. 2x 8800GTS 512 + 2x 9800GTX+. They are pulling up to 500w at the wall depending on the work unit. This allows me to take a rig out of rotation and save some electricity. Got the GTX295 loaded and folding 24/7tonite. Been running into stability issues with the Nvidia drivers crashing, but who knows what it's really related to. I dropped all clocks to stock on the mobo/cpu and bumped the ram up to 4GB. Hopefully the changes work. I had it putting out 15.5K the other night before crashes. Hit me up with suggestions if you know any related to adding stability to this card.
