SLI in Vista64

post #1 of 2
Thread Starter 
Currently, I'm running XP32. One of my 2x1GB DIMMs has died again, and I've decided to replace everything with a 2x2GB pair (G.Skill PK's if you must know). I don't know if I'll keep the old kit or not, but when it gets back from RMA I'll have 6GB to play with. I figure this would be a good time to give Vista a second chance. I have finally decided to suck it up and forget all my previous gripes with Vista, as I have never used SP1. Anyway.
My only reservation is SLI. In XP I was able turn SLI (a pair of 7600GT's) on and off easily through the Nvidia software. I'd select to turn it on or off, both screens would go black for a little while, then the setting would kick in. Can I still do this in Vista? From some of the material I have read, it seems that Vista does not like having SLI turned on an off through software. In XP I even had a shortcut in the taskbar to do it. I understand that the shortcut does not work in Vista. That does not bother me at all.

TL;DR section...Can I turn SLI on and off quickly in Vista without having to reboot?

It works fine from my experience. I change from SLi to non-Sli alot recently when I start to play Mass Effect. It runs better in the Citadel level without SLi enabled. You dont have to reboot, but the screen does go blank and its about a 30 second process to make the switch.

The thing I would be worried about is all that ram at that speed. Vista is more picky about that. I have to run my 4 gigs of 1066 MHz ram at 800 MHz just to remain stable. I would check on the manufacturer's site to see the test results with your motherboard, that amount of ram, on Windows Vista 64-bit. Then you can best determine whether you want 2 gigs of ram at a faster speed, or more than 2 gigs at a slower speed.
