another way to activate AMD disconnect on VIA KT266 (aka cooling bits)
Quoted 23 lines
Hallo,
I have been experimenting with AMD disconnect with my VIA KT266 based MSI K7T266Pro (MS-6380).
LVCool does not yet support KT266, method discussed in LKML in past
(http://cip.uni-trier.de/nofftz/linux/Athlon-Powersaving-HOWTO.html)
does not activate low power mode on my mainboard. The only bit set by this patch is already set probably by BIOS of my motherboard and does not help. So I have checked VCool (http://vcool.occludo.net/) & Wine & lspci and found following bit changes:enable:
setpci -v -H1 -s 0:0.0 70=86
setpci -v -H1 -s 0:0.0 95=1e
disable:
setpci -v -H1 -s 0:0.0 70=82
setpci -v -H1 -s 0:0.0 95=1c
Quoted 1 line
The result is 15 degrees temperature decrease on low system load!
I can attest that this also works on a Biostar M7VIF-X (KT333). Idle
temperature of the XP2100+ is down to 54-55 degC from 68-72 degC. And the box is a bit more silent.
