Best Prime95 for Pentium III Cu 866/133

[Marco]

Hi from Italy! I've two little questions about the various Prime95 versions available for...

1) which it is the better version for my PCs, all based on PIII Cu (Coppermine) with 133MHz frontside bus ?

2) if i run both Prime95 and Seti (no screensaver) on Windows XP Prof., Seti command line program leaves very little amount of cpu-cycles to Prime95 (with default priority settings-> 1)...why Win Me/Win 98/Win 98 SE does it better than XP (changes on scheduler algorithm ?).

Thanks in advance for...

Marco.

P.S: I "love" Daryl Hall/John Oates dynamic duo and their 70s/80s songs.

Win 9x/me are completely different from NT/200x/XP. My guess is that in this case XP is actually doing a better job. It seems that SETI runs at a higher priority then prime95. Try running prime95 at priority 2 and see if the equally share the cpu. Also, note that XP raises the priority of foreground windows (although i think this doesn't work for prime95 since the GUI runs as a different thread)

They will all run equally fast. I'd run version 22.12 or 23.4 from http://mersenne.org/freesoft.htm

Changing the priority of Prime95 to 4 makes it share equally with Seti. Anything less would give it zero CPU and anything more will give it 100% CPU on all NT based systems ie. XP, 2000 and NT

That means that SETI just runs at 'LOW' priority and definately not at idle priority
