I ran one "nice -19 ../burnMMX p" command for over 25.5 minutes and no problems and errors. $ sensors -f acpitz-virtual-0 Adapter: Virtual device temp1: +71.2�F (crit = +206.2�F) k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +122.0�F Core1 Temp: +98.6�F Or was I supposed to run two of them? -- "I like ants, in chocolate.

You should run about _forty_ (40) of them. This also eats up more TLB entries and more switching with nice -19 . It won't run any hotter, (maybe slightly cooler with all the task switching) but will exercise more of the TLB. At the very least run 3 or 5 copies. -- Robert author `cpuburn` http://pages.sbcglobal.net/redelm

I'm still running on the same box as 1999. -- Robert author `cpuburn` http://pages.sbcglobal.net/redelm

I had to run two of them manually earlier. :( > It won't run any hotter, (maybe slightly cooler with all the > task switching) but will exercise more of the TLB. At the > very least run 3 or 5 copies. OK, I am fine to 40 but I don't want to manually copy and paste 40 times. :( -- /\___/\ / /\ /\ \ Phil./Ant @ http://antfarm.ma.cx (Personal Web Site) | |o o| | Ant's Quality Foraged Links: http://aqfl.net \ _ / Nuke ANT from e-mail address: philpi(a)earthlink.netANT ( ) or ANTant(a)zimage.com Ant is currently not listening to any songs on his home computer. |
