8800GT SLI Question

[trigun500]

I just got a second BFG Tech 8800GT OC to use for SLI. This is the first time I've used SLI. I enabled SLI and my computer sees both cards. I go and try Crysis Warhead with little to no improvement. I figured it was my processor bottle-necking my system. I tried the new Battlefield with max settings it's kinda sloppy so I turned it down to medium settings and it's good then.

I just opened Crysis Warhead and how it artifacts la lot. Can't even see the characters not sure why that randomly started happening. Now all other games (TF2, CSS, UT3) run just fine.

My question is: Is my SLI system working properly and I'm just bottle-necking? Is there a way to check if everything is working properly?

Sorry if this is a noob question; I've googled around with little success. I'm downloading 3DMark06 right now.

EDIT: 3DMark06 says my linked display adapters is 'false"

MB: Asus P5N-E SLI
CPU: Q6600 @2.4GHz
4 gigs Ram
PSU: OCZ GamexStream 700W (SLI Certified)
Windows 7 32 bit

Go to your nvidia control panel (right click on the desktop wallpaper and select nvidia control panel) and make sure that SLI is enabled in it.

I've never ran an SLI system, so beyond that I cannot give you concrete advice. I know nvidia has SLI profiles in their drivers, so you might have to choose the game in your control panel and force SLI on. I'm not sure though.

EDIT: According to anand's very old review of the gtx280, you should be getting 50-80% scaling with 8800gt sli.

Yea I do have SLI enabled via the nVidia control panel

sli'ed 8800 gt's work very well in crysis. I had that setup for quite some time. while playing crysis, open the console by typing the tilde key ~ next type r_displayinfo 1

That should give you a whole lot of information including whether or not sli is working. If it is it should say something to the effect of multigpu enabled.

Honestly, I wouldn't be surprised if a simple driver reinstall cleared things up. Computers are stoopid sometimes and simple things can fix a lot of problems

ahh yes you might have to enable sli inside crysis. Do a search for "gamermax crysis" config, download that, and put it in your crysis directory. It is a mix of high/very high settings at near high performance.

I tried the console with SLI enables and without. With it on says "MGPU" off it doesn't show anything. So am I right to assume "MGPU" means multigpu enabled?

I also just loaded a new game in Crysis and it is working a lot better; might have been a glitchy save file.

I'm still going to make sure SLI is working properly.
