SLI and Linux

Right now I have the box dual boot, XP SP2/slamd64 linux and I have "Quiet & Cool" disabled and the cpu fan disabled in the bios, but when I log out of XP all the fans spin up faster and as soon as I'm at the login prompt they spin back down.

Well the thing is, when I log into X windows in Linux, they still keep spinning faster and won't spin down.

I was hoping there was a SLI setting in "nvidia-settings" similar to Nvidia in Windows to enable SLI.

Does anyone know if possibly Quiet & Cool has to be enabled in the bios in order for SLI support to work proper, or what the possible cause is for this?

THANKS

P.S. With Quiet & Cool disabled is this normal for all the fans to spin up faster when logged out of XP? I could of swore when I had it enabled they did this as well.

Yes, using the propriatory nvidia drivers do support SLI actually. With the 8xxx series drivers they do.


I am a bit confused though...

Cool'n'Quiet is a AMD thing right? And SLI is a seperate question, right?

Well with Cool'n'Quiet you'll need to install some sort of deamon or desktop proccess to control the speed of the CPU and such.

Also the exact thing you'd want to do will differ a bit from distro to distro.

If you were using Ubuntu I'd suggest installing powernowd to controll the cpu stuff and making sure that you've modrobe'd powernow-k8 and stuck the module name in /etc/modules (so it'd get loaded next time you reboot).

Also you may have to have the cpufreq 'userspace' module in /etc/modules, although I can't recall the exact name of the actual module. It'll be in /lib/modules/<yourkernelversion> directory if you want to grep for it.

I don't know if that will control the fan or whatnot. It should give you control over the cpu speed and I expect that the cpu fan will get controlled accordingly. I (unfortunately) don't have a AMD64 machine to see how it acts.

I don't know about the bios settings.

For the propriatory linux drivers you'd want to make sure that you have the latest version of nvidia drivers installed. With the new drivers Nvidia includes utilities to tweak the card and edit your xorg.conf automaticly for you, if you want.

I expect that they now include a utility to control SLI on supported cards. It shouldn't be difficult to use. You'll have to read the nvidia README files or see the nvidia linux forum for specifics though.
 
Is SLI also supported on Windows 2000? Last I heard, it was only supported on Windows XP and not anything else inclduing WIndows 2000. So it is now supported on Linux. That would be great.
 
Oh well all this asking and I can't get a NIC card into the last pci slot, because the onboard LAN isn't supported. This Abit KN8 SLI board below the pci-x slots leaves very, very little room, so all I was able to put in was a sound card.

No biggie, figured a $2000 box for gaming doesn't need Linux, LOL, I'll just put Linux back onto my XP 3000+ box 😉
