hello all

i got this problem with running GTX 680's in sli with 3 monitors i get about 1-5 fps i can't even get in to a game. when on the desktop its fine and loading up web sites with no problems but as soon as i load a game i get like 1-5 fps with 3 monitors running.

but if i take one of the cards out and run 1 card with 3 monitors it all runs fine on every game i get about 55-80 fps

but putting the 2nd card in and run in sli with 3 monitors i get about 1-5 fps can't even load up any game

has any one had this problem or know of the problem and have a fix for this please help

also the sli runs fine with 1 monitor just got the promlem with 3

pc specs:

PSU RADIMax RX 1000watt AE 80+ gold
motherboard ASUA M5A99X EVo
CPU: AMD FX8120

you have to configure the sli for 3 monitors(i dont know how look it up... sorry)

55-80fps with one card? if that's true you clearly bought one too many GTX 680's.

haha thats true but... a possible answer to your problem is too configure your system so it knows that two cards are powering 3 monitors, search the web for some videos im sure there out there.

There is a problem with the 990 boards and 6xx sli surround. I have 2 670's and they do the same when I try to run surround. I've read that amd and nvidia know about this issue and are working to fix it. Who knows when that's gonna happen so I am saving up for 3930k and doing away with my amd. Until then I am running one card while the other sits in a box. :(

hello mate thanks for the info i'm just running one card at the mo the thing that gets me is ppl as running it ok as i seen some vids on youtuberunn 680 SLI its a pain

All of the 6xx sli surrounds that I've seen on youtube have been running on Intel platforms. I haven't been able to find one running on amd 990 platform yet.

It's because of the board + surround. The 990fx boards have been reported to have this issue with the 600 series when sli is enabled and there is also a surround available. There's a huge topic in the nvidia forums about it (although the forum has been under maitenance for quite a few days) and basically nvidia admins say that it is not fixable with a driver update. They are currently working with AMD to solve the issue, which should be corrected with a bios update. To be honest there has been around 2 months and there's no fix yet, I'm afraid (yeah I got a 990fx too) that maybe there isn't a solution. If I were you I'd either try to sell the mobo + the processor and get a SB intel board, since you already have 3 monitors. Regards

your CPU could be bottlenecking your cards... I like AMD but those are some very powerfull cards so mabey you should think about upgrading CPU's to a different version.

Is not the CPU, is the whole 990fx platform. Man actually I wanted to ask you a question. How does your sli work in a single monitor?

Thanks for the info man, I hope to get my 2nd card soon now that they are a bit more cheaper (in my country) . Regards!

Sorry I used the wrong word, the proper was "chipset", by that I mean that the issue is not only limited to fx processors running into 990fx boards, but it also applies to any other AMD processor running into a 990 board, which is sad because you can't just solve it getting a Thuban or a deneb . Although since the problem is limited to the surround config, users like me who expect to use the sli in 1 single monitor only will find a nice oportunity to be geared up to the future . Cheers
July 8, 2012 4:31:00 PM

do you know if that applies for a 970a? i have a GA-970a-ud3 and I am going to eventually sli my 670
July 8, 2012 5:57:21 PM

Well it's a am3+ socket so in theory it should have the same issue, although I'm not sure. Perhaps you can ask that question in nvidia forums, gtx 600 series 990fx topic issue , but they are currently under maitenance. Good luck
