My Haswell Setup

[Lloyd_mcse]

Just rolled back to 314.22 drivers, posted on the Nvidia site - Here, not sure if you think I should add something? My brain is fried lol
Tired FIFA worked fine but had nothing to compare it to as I always had Vsync on before so was limited to 60 FPS

Cool, yeah that looks fine.
Let me know how it goes with 314.22.

Let me know how it goes with 314.22.

Definitely smoother but still only a max of 50 FPS consistent at 45

What about on BF3?

[Mark1978]

Same mate. Starts off superbly well (150+FPS) then drops to 30 within 3 minutes.

[Lloyd_mcse]

Can you post some screenshots of GPU-Z, with these 314.22 drivers installed.
Same as previous one (in game), and take some in desktop too.

The only thing I see is that the Performance Cap is no longer there, where it was with 331.40 (see sensor page).
With the other drivers it was VRel and Util listed as performance cap.

What are others getting as a Perf Cap with SLI setups?

I don't have anything listed on my GTX 770, but when I was having issues with it I had a Performance Cap of Util.

I would fire off a couple of emails to EVGA and NVIDIA, EVGA might have a newer BIOS for the cards, or be able to fill you in on any known issues.

Do you mean through support tickets etc?

[Lloyd_mcse]

Yeah, here we go ...

Thought as much, I send off a support ticket earlier this afternoon. When I get home from work I will send one to Nvidia too.

Cool, I'd PM ManualG on the NVIDIA Forum too, he's the mod over there and usually has the latest bug reports etc.

I'm getting a cap of VRel and VOp on both cards whilst playing BF4. Wasn't fast enough to catch it on the 2nd card.

However that will be different to the TITAN and other 7 Series cards because GPU boost 2.0 works on temperature and not voltage limitations.

The main thing I do notice that is odd with Mark's screenshots is that the game is only using 20% of his second GPU. Even with a CPU bottleneck, SLI should be distributing the load evenly across the two cards.

Steve and I just did a test on FIFA. Steve has 2 x Palit 680's (2GB) in SLI

We both went into the arena, didn't move the player and the results are as follows:

Steve SLI 4.6 Ghz

Steve SLI 3.50 Ghz

I got more FPS with SLI disabled than when it was enabled and Steve had roughly 200 FPS less with clock speeds on his chip.

[Lloyd_mcse]

Thanks for confirming that Steve.

How strange. do you get better FPS in BF3 with a single GPU too, or do the FPS still degrade?

EDIT: Degrade in 314.22

Just a quick update. I have emailed gigabyte, Nvidia & EVGA to see if there are any compatibility issues with my rig, no answers thus far.

I have checked my CPU usage during game play (BF3 & 4) and it doesn't go above 71% usage on either.

I did change the SLI bridge and there was an immediate improvement to a max of 80 FPS on BF4 but it wasn't sustained. Alt tabbing definitely has an effect where you can alt tab at 80 FPS and come back to 30. I have had highs of 135 in the chopper on BF4 with an open server with no one else on it, but again not sustained or repeated.
