Nvidia 8800GT Card
Oven-Bake/Solder Reflow
Tip (Feedback)
(Apr 2012) A few more positive reports on the "Oven Bake"/solder reflow fix (example youtube video) for some Nvidia 8800GT card problems in Apple's Mac Pro forums. Some earlier/older threads on Nvidia 8800GT card problems have updated posts (here and here) on the oven-bake fix. As always, YMMV. (Some owners had also tried older tips on removing dust buildup, redoing thermal paste, SMCfanControl to boost case fan speeds for better cooling, etc.) I was skeptical when I first heard about it but oven baking posts in Nvidia's forums go back to 2010. Be aware DIY 'reflowing' the solder balls is often not a long-term fix. (It's been used on other chip problems in AVRs, etc. but the solder joints typically fail again.
