thanks for the new forums, George. (fora?) at work lately i've been trying to set up a dual-P4 win2k system with prime95. but when it boots only one of the prime95 starts up when i log in. both are set for start at bootup each with cpu-affinity hard-coded. i've tried with both 22.7 22.8 .

hello Roland, could the CPU be overheating? what is the ambient temperature in the room? have you verified cpu fan and other case fans are operating? is plenty of hot air exiting the power supply fan? P4 has thermal protection which will slow selected areas of the chip, whichever portions are

hi Aaron, thanks for clarifying your position! i'm a simpleton who lives often below curb-height, and think poaching=stealing=wrong. this exponent poaching seems like a sort of stealing to me and it would surely tick me off vastly if i found my 33M exponent was checked in a day before my PC

Mersenne: mprime iteration time increase, linux athlon, 21a-21b /also: P4 saga

2002-02-01 Thread Steve Elias
hi, does anyone know why i see a ~25% iteration time increase by moving from mprime v21a to mprime v21b. (i'm considering moving back to v21a since it appears to run faster on my 900 Mhz redhat linux.) regarding the fried P4 machines, the saga continues. despite repeated requests for full

thanks Brian everyone who has responded i do also have a 900 Mhz Athlon machine too - running redhat linux. i now have my win98 1.8Ghz PC back, supposedly in working order, supposedly the problem was some other s/w i had installed. :| i had installed very little on it beyond prime95. so

here are some instances where i have damaged computers by (capriciously?) running prime95! 1 - i just got my wife's toshiba laptop back from toshiba warranty service. running prime95 for ~6 months on it caused the fan to die, and then the laptop would overheat shutdown even without prime95

hi folks, thanks for all the responses regarding my Frodo-style cpu-slaying with prime95! Mary, it's great that your dell laptop throttles back the cpu when it overheats. that's smarter than my P4 desktop with Asus motherboard, and also smarter than the toshiba 'satellite' laptop. if you
