Cheers.

Are you saying that the cards will be more or less sandwiched together? If that's the case you can expect the top card to get a bit hotter than the bottom card simply due to lack of airflow to it. An aggressive custom fan profile could help with temps a bit, but overall it's doable. I have 2 Sapphire ref 7950s in the Fractal Design mini and they are sandwhiched together and temps are too bad. I'll post up so info on that when I get chance to take Screenshots and what not. Hope that kind of answers your question

But holy s**t 7970 crossfire and you getting dips to that level ????? I suspect its a crossfire driver issue, not a driver AA issue. But its well known that MSAA in this game is VERY expensive - maybe the game needs optimizing still. (note the Feb 14th leaked beta 8.96 is meant to be good for BF3)

Heres my experience of MSAA in this game, all at 1080p All settings maxed except MSAA being changed. Post process AA is off as i find it too blurry.
Note: I experience the game becoming choppy at approx 54fps on my system so I want a setting that provides at least this min Fps.

GTX 580 3GB @ 900/4200
x2MSAA in 64 player mutilplayer = holds 60 Fps majority, few dips to mid 50's in Vanilla map,few dips to mid 40's in B2K maps = Just some areas of B2K maps annoying and sluggish (hence buy a 7970)
x4MSAA in 64 player mutilplayer = holds mid 50's Fps majority, dips to mid and low 40's in all maps and sluggish feel = Not really playable for me as annoying.
7970 @ Stock
Same as above
7970 @ 1260/6200
x2MSAA in 64 player mutilplayer = holds majority 60fps everywhere, few dips to mid 50's in B2k maps = No sluggish areas, feels smooth everywhere
x4MSAA in 64 player mutilplayer = holds 60fps majority in all Vanilla maps, Dips to low 50's/high 40's in B2K maps = Playable for Vanilla maps few sluggish areas in B2K

The solution for me is to run x2MSAA with SMAA injector (and disable ingame postAA) = Superior AA and only a couple of Fps hit on top of x2MSAA.
x4MSAA just feels a bit laggy on the B2K maps still in some areas.

Also these cards need a nice OC to come alive, but I think we all know that !!!!!

How do you set MSAA, FXAA, etc? I haven't checked because I haven't played in ages, but isn't there only one AA option and a slider bar in the BF3 settings menu?

Little less sandwiched, but still they will be preety close to each other, i could maybe insert second card in last slot, but i cant find the bridge long enough for that.

MSAA is ingame
Post process AA is ingame (this is ingame FXAA but blurs everything)

These are 3rd party injectors.

Again, anyone figure out how to enable Unofficial overclocking mode in AB when using 12.3? If I apply it, all clocks go to 0 and wont take a change. If I disable it, it will overclock to 1125core no problem.

Anyone know how to fix this?

Thanks,
Hambone

1. Uninstall the driver through catalyst manager.

 

2. Clean it with Atiman Uninstaller v.6.3.1

 

3. Install RC11 http://support.amd.com/us/kbarticles/Pages/RC11Driver.aspx 

 

4. Upgrade (overwite RC11) with 12.3 Pre-cert. Do not perform clean install. It will interfere with ULPS and 3D clocks or in Power Saving Mode.

 

5. For Crossfire user;  Catalyst 12.2 CAP 1 http://sites.amd.com/us/game/downloads/Pages/crossfirex-app-profiles.aspx

 

6. Reinstall Afterburner if you have to then verify ULPS and unoffcial overclocking.

AFAIK you need to replace the missing atipdlxx.dll file into system32 and syswow64 folders.

Uninstall AB, download the file and copy it to locations, reboot, reinstall AB.

Im using the -XCL mode with AB beta 14 with 12.3 pre cert, no issues overlclocking here.

Overkill? Yes, for a reason but not overkill for Crossfire user thumb.gif

Yes I'm a Crossfire user. So go back to RC11 and just install over it. DAME, wish I knew that before the process of installing the 12.3 biggrin.gif Thanks for the reply. Like I said, it worked fine on RC11 and no issues once I enabled Unofficial. I'll give that a try.

Thanks both of you.
