CPUIdle on AMD's Duron and XP

[the_master]

When I had a BP6 with dual Cel500@600 in w2k, I used CPUidle 5.8 and I got a huge temp difference (42-->~30) but now with my Duron (800@1006-A7A266), it doesn't seem to work, no temp difference at all, can't prgms that uses HLT commands work with durons?
Soon I will switch to a XP "1500+"(1.33ghz), will it work on that?

Unfortunately, the software CPU cooling progs don't work with the K7 CPU's. Well, maybe some of them do, but I'm pretty sure that CPUIdle doesn't. It's said that you can cool down the K7 processors by using WCPUCredit, but messing with the internal registers of CPU's kinda scares me!

Yeah, that is kinda scary...Messing with settings only got me into trouble.
Why doesn't it work on AMD's cpu's? Is there something special about them, besides being better then Intel? ;)

I guess that the processor's internal "microcode" isn't the same with both AMD and the other big co's CPU's.

Win XP seems to have cooling built into it. It issues the HLT command when the processor is doing no work. My machine with XP is a cool as it was with Win98 or Win ME and a cooler.

The machine however has a PIII not AMD.

I sort of figured that, win2k prof. is shipped with the feature enabled, but it only seems to work on portables (don't know why).
