SLI issues (GTX 680)...

post #1 of 7
Thread Starter 
Just added a second 680 yesterday and, initially, everything seemed fine. However after testing some games today, things are not right.. Perhaps I haven't configured SLI correctly?
Anyway, the first issue I had was flickering in games. This was solved by re-securing the SLI bridge. However, now there seems to be a brightness issue, which occurs only after exiting out of Crysis 3.. Basically, after exiting back to the desktop, my monitor's brightness appears to have reduced. Again, this only occurs after playing Crysis 3. On a fresh boot up, the brightness levels are normal. That is the main issue, and top priority right now. Anyone have any ideas as to why this would happen? Are there any steps I should take to ensure SLI is configured correctly on the software end? I have it enabled in nvidia control panel, that's about it.
And aside from that, performance isn't great in Crysis 3 either, although I have experienced zero crashes so far or any visual issues in-game. Although, I was getting major stuttering in Hitman Absolution...
I'd appreciate some help, thanks.

Btw - temps are normal. Both idle low 20's/mid 60's load

When you added the second card did you install the drivers again? Running the 314.07 drivers?

Hi. Yes I was running slightly older drivers at the time I installed the second card, so updating to 314.07 was the first thing I did. I took all the necessary cleaning steps beforehand also. And I even re-installed the drivers again, after suspecting them to be the cause of the flickering issue (which was in fact caused by the loose SLI bridge, as mentioned). Do you think this brightness issue is most likely driver related?

Oh and if this helps, I ran 3DMark13 and my Firestrike score was 11065 (GPU score: 13857). Is that anything to be concerned about? My cards have been OC'd to 1189/3400.

Can't explain the brightness issue-- could be monitor drivers, GPU drivers, etc.
You Fire Strike score seems about right. Here's mine at all stock on CPU, GPU, and Nvidia Control Panel:

That's a relief, I'm glad it's normal. Thanks for sharing your score.
And in regards to the monitor drivers, the driver section on Dell's site confuses the hell out of me. It's not clear what to download. I did get drivers (of some sort) for my model off there some time last year, but have no clue whether they were the correct ones or if it was even installed properly. So if anyone could assist me there I would appreciate it.

Thanks. It seems I have that driver installed already. So I guess that rules out an outdated monitor driver as the cause..
Guess the best thing to do is just wait it out for new gpu drivers. Anyway thanks for your help. If anyone has any further input on this, it would be welcome.
