OP try to flash the 6950 to a full 6970 BIOS this way the timings and other marginal differences will be updated to 6970 standards and the CF synchronization will be a 100%
its already flashed to 6970 bios

You're actually running 3dMark06, with a setup like yours?

Seriously?

Dude, it's like 6 years old, designed for testing performance on like single 7900GTX cards. It's 1280x1024 with no AA. The problem is: it is utterly and completely CPU-bottlenecked. For reals, you should un-install 3dMark06, and never run it again on this setup. It's a completely inappropriate test for a rig like yours.

Crysis 2 I know nothing about, but if v-sync is on, then in theory you should be running at 60fps at all times (I mean, technically, you COULD get less than 60fps, but w/that rig, I shouldn't think it would ever happen)

Now, what is your GPU score in 3dMark11? Because 3dMark11, unlike 06, should show you some decent scaling from the third GPU for sure.

If you just want to see if the third GPU is working period, then do a run of 3dMark11 with just the 6990 (i would physically remove the 6950 for the purpose of this experiment), and compare against what you get now.

If the tri-fire doesn't get a GPU score that's at least 35% higher than the 6990 alone, then something may be wrong. And obviously if it's the same score then tri-fire isn't working at all.

To be properly testing this rig, though, you should be running stuff at higher resolutions. Try the Heaven bench with 2 vs 3 cards, totally maxed at 1920x1200. THAT is a proper test of a system like yours. Or Vantage using the Extreme preset.

Some other good benchies to try on your setup are: Aliens Vs Predator, Just Cause 2, Stalker - Call of Pripyat or Clear Sky, Lost Planet 2, Unigine Sanctuary ...

Those all have free benchies available ... they're either stand-alone benching apps, or they're included with the game demo ... and they will all give your cards a good workout if you max them out at 1920x1200

lol you are the only one paying enough attention to realize he posted 3DMark06

+1 for that and + shame for the rest^^

You passed the test! well done.. lol.. nah just kidding. I did read somewhere that 3dmark06 is an old program, thanks for clarifying that. Ok, I'm gonna do all the things you just mentioned here and see what happens. Will report back

cheers guys.

ok, did some benchmarking with Heaven 2.5 and 3dmark 11

Settings for Heaven 2.5:

API = DirectX 11
Stereo3D = disable
Shaders = high
Tessellation = extreme
Anistropy = 16
Anti - Aliasing = 8x
Fullscreen
Resolution = 1280 x 1024

3DMark 11 - Performance Setting

Single 6990 (Performance Switch)

3dmark11 = 9218
Heaven 2.5 = FPS 51.0 Score 1284

Single 6950 (Flashed to 6970)

3dmark11 = 5386
Heaven 2.5 = FPS 26.8 Score 675

6990/6950 Trifire

3dmark11 = 10888
Heaven 2.5 = did not complete as 6990's temps sky rockets to 106C


definitely something wrong here.

I'm using the 11.3 drivers and 11.4 CAP1

what do u guys think

I think I see what's going on here.. Your 6990 is massively underperforming in trifire because the temperatures are way too high.

whoa, my 4870x2 was crapping because it was reaching those temps, i had to send it back, im not sure about the 6990, but it may be an issue, i think it would be an issue, take the 6950(70) out, rerun the test, if it still gets that high, rma it.

Well, usually GPU's start to throttle/slow down massively around 90c - 100c.

Once a wire got stuck in between the fan of my 5770 and performance went downhill pretty fast when it went to 110c.

Those a really high temps -- are the cards right next to each other by chance? If they are, try to wedge a piece of cardboard or something between them to let some air in. Also do you have a side fan blowing in directly on them. That will also help.
