SLI issues/concerns and stuttering (GTX 200, 8, and 9 Series)

At first, the only things that bothered me was lack of Tripple Buffering and poor Vsync performance.

Then, with some driver updates, image in SLI AFR mode become yellow-ish (probably genlock problem, like most significant bit of blue channel occasionally drop 1->0) in 2560x1600 mode.

About the same time Nvidia drivers started to use high-resolution software timer, insted to hardware, to do a flip(). This introduced visible tearing in 2560x1600 in first 10-40 image lines when VSYNC ON.
This driver update aslo improved AFR Vsync performance alot (it was always worse than single card before).

With FW92.91 (1 month before 8800GTX release?) and later drivers SLI support just disappeared, and never came back.
Last working drivers: FW91.47. (I wonder if Asus used hacked Nforce4 Ultra chips instead of nf4sli?) End of story.

current rig:

21" IBM CRT = no SLI problems
22" Mitsubishi CRT = no SLI problems
25.5" Samsung LCD = no SLI problems


Everything is currently smooth as butter here

No issues at all.

I' ve had 8800GT SLi, 8800GTS 512 SLi, 9800GTX SLi and GTX280 SLi.

Works like a charm. Sometimes with new games or demo's a profile has to be added in new drivers, but otherwise no problem.

I would love to resubmit my vote, but can't I had selected 'no problems but some stuttering', but ever since the last two driver releases things are looking up. I'm very happy with my SLI setup now, more so than my last SLI rig with a pair of 7800 GT's.

the G7x series, even in SLI really are not powerful enough to properly push a resolution like 2560x1600. I have my 7900GTX SLI rig on a 24" LCD (Benq G2400W) which has a max resolution of 1920 x 1200. If you read G71 reviews you will see performance drops off badly after this resolution (can't remember the actual reason, but there is one).

The FW 9x.xx series were just plain troublesome fullstop IMO. I had plenty of profile troubles back then, just about drove me mad. Fortunately the driver situation has improved greatly since then. I have a friend I sold an old 7900GT 512mb card to, he likes oblivion, I'm still quite shocked at how well that runs on his system with the latest few drivers compared to how it used to run for me early 2007 with SLI'd 7900GTX's.

I'm liking my 8800gt's in SLI,they work well with some games,and excellent with others.

I just don't notice these micro sudders in SLI.I am glad .I have played with SLI with certain drivers that did give me little pauses and it drove me nuts.After a driver update it went away and I did'nt notice it anymore ,That was on my 8800GTS 640mb system ,gameing with a Dell 2405 at 1920x1200.

I'll be testing SLi soon. It will be interesting to see how it behaves on true 16 x 2 with the massive bandwidth available from the X58 platform.

Bah. It's up and running but the SLi bridge I have isn't the right length. Going to have to get one that's flexible.

I'm also waiting on a 1366 adapter for my Thermalright Ultra Extreme.

I ordered the bridge from Sidewinder computers. Hope it works.

my 1st sli experience was really good starting out then i started gettin wee lock ups coming out of games.after abit of testing with one card which i thought was the kulprit (BFG OC EDITION )it was the card that was faulty which i was thinking anyway. playin crysis my pc would just power off sometimes with out warning .now with my expertvison 280 gtx all is fine for me now im dreading gettin a replacement bfg to go though all of this again so im thinking of ebaying the replacement card and gonna try and get another expertvision 280 gtx hopefully that will solve all of my problems. i hope.

Hello all! I just got on this forum, great advice going around!

well here is my tale of woe with sli

I just purchased a 3d animation/epic gaming rig from Velocity Micro, veryveryvery new computer, just came in 2 weeks ago. Great rig, runs like a ferrari, but my sli is having major problems. I have dual Nvidia gtx 260 core 216's and 90% of the time when i run a game in full screen it stutters, strobes, and the frame sometimes tears and smears to the side. The only game i really have to run Sli with is Crysis and the intro video (ea games logo thing, nvidia, and intel super mini clips at the start) tear to **** and back, but the main menu is great. No problems till i start the game, then it starts to tear, stutter, and stobe. I've updated the drivers from Evga, nvidia, and through the Device manager. Nothing really works. But what is really strange is when i run the game in windowed mode it runs great! ??????????? Any idea's why this happens?

My rig:
MSI X58 Pro-E mother board
Dual Nvidia gtx 260 core 216's
Intel i7 960
6g ddr3 ram
22" Asus monitor 1920x1080 resolution.
Windows 7 home premium
Direct link to my build from Velocity Micro.

Any help would be greatly appreciated! Thank you all for your time.
