8600GT inherently unstable?

post #1 of 3
Thread Starter 
Title pretty much says it all. Ive had 2 8600GT graphics cards that i have used for folding, and i couldnt help but notice that both of them are causing a crapload of early unit ends and unstable machines. The first one, a Zogis 8600GT, would do it at stock and at the high overclock i had it at.
I just got my mitts on a PNY Verto 8600GT OC, and naturally, i overclocked it before setting it to folding. First day active it got 3 units done and bombed a 4th. Naturally i backed down the clock speed last night to more reasonable numbers (650/1450/730) and when i got home today, all 4 units it had worked on today had bombed out hard. Now i have rolled the clocks back to stock, and am now waiting for the GPU client to either throw another exception or complete the unit.

This is the second card that has done this to me of the same generation, and i am beginning to think that the 8600 series is simply too unstable to use as folding cards. Am i right in this assumption or have i had really bad luck so far?

also, temps are well under control (highest ive gotten it to was 92C during a furmark run, folding has it to out at about 74c). I stuffed the folding system into my old rosewill case and equipped said case with a pair of 1800rpm 120mm fans, and the card itself has a 92mm fan to boost extra air across it to keep it cool, cause the card itself, not just the GPU, gets very warm.

I had heard things about the 8600, never had one myself. A friend of mine had one crap out on him after a year of normal usage.
