I have used the latest drivers for my mobo and Graphics but still cannot get SLI to work at the 25% XFX stated. I get 10717 single SLI 11687 and absolutly no performance increase in games with or without AA Af v-sync high or low res nothing seems to work and im all out of friends please help me...
What resolution are you gaming at? Do you have sli enabled in drivers? Also, make sure both cards are being registered. Try using gpu-z to see if indeed both cards are showing up. What games are you using. some games don't support sli, even if there is a profile for it. I know Mass Effect doesn't, Shaun White Snowboarding, Gears of War, also, I saw no benefit in sli for Crysis Warhead, either. GRID, COD 4, & Devil May Cry, Far Cry 2 all benefit, I can vouch for them. Also, almost all Source games, too.
Res is usually 1280X960 or anything between 1024X768 onward, yes SLI is enabled hence the 11687, GPU-Z yes it shows up, Grid I have, even with one card and v-sync on with upto the 16qssc or what ever it is you know though, I get between 30-55fps on one card in SLI...nothing no performace increase absolutly nothing same fps or such as in single mode, bet that has confused you now as to why.
your resolution is your issue. SLI doesnt really shine till 16xx and up. you will see a bigger jump in a single card to SLI in a higher Resolution.
My monitor dont support above 1280X960 shurly I would still see the benefit in graphics, UT3 is slow with everything turned on with or without AA Af V-Sync I only get 30-50fps with or without SLI...
well ur not going to see the performance boost in SLI until u go to a higher Res. as far as ur issues with games, try tweaking ur settings a little. i've used SLI for some time now, and i will never go back to a single GPU. in nvidia control panel, try messing with these settings: for display mode, if ur using 1 monitor set it to single display mode. SLI rendering options- try the diffrent settings there are. i find for my setup AF1 is the best for me.
what he said. I am gaming at my monitors native rez which is 1680x1050 and SLI is jammin for me.............
Like I said I have used AA and AF with and without on UT3 and grid and I see no performance difference at all no increased fps even on a single GPU UT3 on full settings in any res struggles SLI nothing at all...

Maybe your CPU is the bottleneck? Try overclocking it a little, if you get a big jump then there's your problem. If not, meh, SLI can be finicky.
the cpu is the bottleckneck at those tiny resolutions. you SHOULD be able to use more AA and AF with little difference in frames
do the benchmark with 16x antialiasing (or higher if you can), always at maximum resolution and check differences. if not then try in games, 3dmark06 = cpu bitch
I have only just got my new mobo on my old one the M2N SLi deluxe I could not overclock only to 3224 from 3100 any more and the system crashed, will try overclocking on the new.
Overclocked my CPU to 3358.4MHz nothing no performance increase at all on UT3 still as laggy and choppy as before lol...
Sometimes you can force enable a higher resolution at the cost of lowering refresh rates if your lucky. My SDM-HS95P is native to 1280x1024, but I can force 1920x1080 in CCC without panning at a slight loss in 2d quality at ( I believe ) 60hz. I'm not sure how that would translate in the NV control panel since it seems to have less flexibility than ATI's CCC, but take a look around. It could be a half decent temporary fix for the time being. Otherwise you could just OC your cpu a little and enable more AA and AF since you won't lose much, if any, fps by doing so.
i just bought another 8800gtx to sli this rig my 3d mark 06 was 10,400 with 1 card sli is only 11,300 but games are humming along at 1680x1050. not as good as my gtx 295 but at 1680x1050 or higher sli will shine
Tried 174 175 180 and 181 none give me any performance boost like said I cant even play UT3 on full detail on any res with or without AA or AF...
What are your temps like for the cpu, gpu's etc? Have you tried each card one at a time in the main PCIEx16 slot? ~John
