What was your original BIOS? Do you have a voltage locked card?
Mine was voltage locked, came with FX0 and wouldn't take any other BIOS.

Interesting... My cards are voltage locked cards that came with FX0 too. I successfully ran FZ1, FY1 and F43. I am about to try FX1.Mine was voltage locked, came with FX0 and wouldn't take any other BIOS.

I assume the card performs well in games? What is your Valley score on HD Extreme?

Wow...you know what I just tried? Changing the "Display Scaling Mode" in 3DMark from Centered to Stretched. Result? 1500pt jump.

I don't know if that's high enough, but I can't explain how that setting alters the score.
atiflash in a DOS environment.What did you use to flash them?

Well, I got another new score. This one jumped over 1000pts by simply raising the Catalyst "Power Control Settings" from 0 to 20%.

Makes me annoyed what other things I'm missing...

FX1 locks up as soon as my PC puts a load on the cards. I am sticking with F43.
Best I can figure is the power control setting is there simply to improve power consumption measurements. Everyone should just set it to +20%. It's not putting any additional power to the card, it's only allowing it to draw more if needed.
My card reports 81.5% ASIC QualityI got one of those sapphire 7950 deals, mine reported a 49% ASIC quality, something stupid low.
It still overclocks ok, it does 1100/1550 with just catalyst driver, no voltage adjustments.
Still an awesome product. I had a 7870 also and the 7 series is great, esp since the last couple generations were more incremental upgrades.
I last had crossfire 6950s and I think a single heavily overclocked 7950 is almost as fast as stock dual 6950s.
Has anyone seen reviews of an overclocked 7950 vs a stock 6990 at 1440/1600p. I'm thinking side grading. I don't want a small downgrade, but not too much.
Did you change your bios? It is reaaly weard. May be the problem is in your PSU.
You can check whether the voltage shown with the software using by you is real - try to connect a multicet - you can google how it works, because i can't explain it very well in English. Basicaly you must put the pin of the multicet in one ot psu connectors, but with some settings on the multicet - this i can't explain.If your reffering to me i have been thinking it may have something to do with it. i have more than enough juice unless its dieing which would be very odd. And no, no bios changes have been made
Well, for now, with only 2-3 games so demanding, i don't think it's a worthy deal to grab 2 or more 7950s. May be in the future, but not now - for example i don't like crysis, far cry and tomb rider - i don't intend playing them, so what is the point for me to grab two cards - all depending of the customer preferences...I made two new videos of the scene in Crysis 3 Only Human level, where Prophet rides the Vtol. I chose this scene because it's automated up to the point I recorded, so it would be the same for both recordings. Also there's a lot of camera panning, which is the worse motion for the viewer, if there's stuttering.
Here's the video of the 7950 crossfire. This is how I play and this is what I see. 60fps vsynced. Actually it's better in real life because Crysis 3 is very cpu heavy and Fraps needs a lot of cpu as well so its difficult to keep a steady 60fps, but still it's good enough.
This is the video of the single 7950 at the same settings. I only disabled vsync for this one, otherwise I would be getting a steady 30fps, thus artificially making my point even stronger on a difference that is already huge.
What I see here, is two cards running the game at perfect smooth 60fps and still have some spare cycles, while the single card is struggling to hit 40fps at full load. (<-this hints at greater fan speed, thus more noise, another benefit of dual gpu)
Call me crazy, but this is what dual gpu is all about. Effectively almost doubling your processing power pool, so you can use it for a smoother framerate and overall better gaming experience. I'd suggest to people that are quick to dismiss dual gpu systems, to actually sit in front of one and do some real life testing, because I do, for more than 5 years now (voodoo2 sli doesn't count I guess) and I have mostly faced situations like the one described above.
I don't defend AMD here, but dual gpu solutions. Both my secondary system with 570 SLI and my tertiary with 5850 CFX, still exhibit the same behavior, alas with lower settings.
Actually my older 5850 CFX system would be far more suitable for comparisons, since it's much more gpu power starved and the second card can do wonders, but it lacks the cpu power to provide good fraps recordings.
This post is aimed at people that are preaching single gpu powa at any cost and as a counter measure to recent crossfire frametime findings. I know that me using vsync alleviates most or all of these issues, but this is how I believe proper gaming must be done.
It is also a good example of what 60fps gaming vs less than 60fps gaming looks like.
