Dust should be reponsible for the slowdown. Thank you and everyone else, both on- and off-list, for your helpful suggestions. I took the cover off and had a look. The HSF looked like the inside of an old vacuum cleaner, so I used a new one on it. :-) The fan speed is now back up to 4600, and the processor temperature has dropped by 10 degrees. While this is probably what tipped the system into instability, I'm not convinced it is the sole cause of the problem, if, as you say, 50 degrees is not excessive. My prefered contribution to the project for the past several months has been to do exclusively P-1 testing, but I have taken George's advice and started a LL run with roundoff checking on - actually a DC, so that I can check for it's appearence in lucas_v.zip. > to test your processor, i recommend www.memtest86.com > it is a memtest in first place, of course, but it also tests the processor > > You can test your system with madonions 3DMark 2001 SE.
