Thx for the replys and sorry miss read ur first post JdB was not totally awake at the time.
This system was a prefab although I hate them and would rather custom build one it was smthin I had to get last minuite, it's a packard bell prefab so dunno if they didn't test the system but if from what I read else where that the PSU I have isn't powerful enough then packard will need to be sending a new more powerful PSU to me.

I have the issues in other games too like CoD4 which does support SLI. I've changed the cards around only thing I haven't done is to uninstall all SLI software and try to reinstall it all.
Just seems strange that packard would sell a product that dosen't do what it's mean't to do :/

One last question but I think it's either a CPU issue or vista, smoke within games seems to lag my system to hell, but the game runs complete fine just when it gets smokey or high particle explostions happen the system lags.

CPU is a 2.4Ghz quad core, didn't have probs on my old system with a 3.4Ghz dual core but the OS was XP with that one also, any ideas with that small prob would be grand and I will try to fix my SLI issues.

Thx for the help

I run all other games on this system with the quad core, and no problems, only prob is when I enable SLI mode and then i get graphics issues :/

Ok so after about 4 months I still don't have my SLI mode running O.o
Have the latest drivers for the gfx cards all the vista hot fixes still no joy :/

Basically I try to run ArmA or any other game and I get tearring or white flashing and then the screen will freeze meaning a system restart.
I've tried to look for this problem on the SLI nvida foums but no joy there either.

It was a prebuilt system, 2.4Ghz quadcore, 2x 8600GS cards 4Gb of ram, im unsure what is causing it, although im thinking it might be the PSU as it's only a 400watt.

Any help would be great or if anyone has had this prob then please tell me how to fix it, currently just running one card so i can still play my games but would enjoy so much to have SLI running.


P.S when I enable SLI mode it runs fine on the desktop soon as I go into any game it's messed up, so thats ArmA, CoD4, Americas Army.
But Entropia Universe works for an hour at least before the screen freezes and I have to restart my comp.

Thx for any help

Tried looking for the driver but it's hinding from me :/
I have the lastest ones for vista the 169.25 forceware drivers.

I have another look if ya can post a link too them would be great.

UPDATE:
Well seems i now have a tearring issue with it also, it's like the game is trying to put it's self on 2 screens and i have only one.
I've change all the options trying diff things but no cigar :/
If I run ArmA on one card it runs fine but I would like to get it to work with SLI going.

Still no luck getting the drivers kinda hard trying to find stuff on nvidia's website that or im looking in the wrong place.

I too have this issue, got a new system and go to run the game in SLI and it just has a white flash on it.
I have a quad core CPU @ 2.4Ghz, 2gb of ram, 2x Gefore 8600GS, and all running on Vista.

Have tried all but different drivers for the gfx cards.
Also have issues with other games also so not sure if it's my comp or the gfx cards.

Will check Nvidia for those drivers see if that fixes things.
Any other suggestions would be helpful.
