[QUOTE=Dubslow;296946]The rule-of-thumb that I recall is that nVidia's are supposed to be safe north of 90C, maybe up to 100C; OTOH, word-of-mouth/rule-of-thumb is never very accurate, and of course, that's for playing video games, not error-sensitive computations. I'd say aim for 80, maybe 85, but anything beyond that is probably too much.[/QUOTE]

On my GTX 480's, anything at or below 95 C is normal. Around 100 C I start seeing problems.

From my setup. The "must keep below temp" is 95degC. Above that and components are throttled.

Fixed in the net version.
Many thanks!

How's 2.01 working for everyone?

Good DCs vs Bad DCs?

Thanks!

The performance is amazing - mean 0.328783 ms/iter.

Hey LaurV/anybody else, I got another mismatch (still using 2.00). Could you run [URL="http://mersenne.org/report_exponent/?exp_lo=25831787"]M25831787[/URL] and tell me when you submit the result?
