Got my second 7900GS in the mail yesterday, heres the results

These are de-badged Gainward Golden Samples and overclocked from 450/660 to core/mem to 645/765.

The one I bought first would happily bench at 650/800, but the second refuses to budge from the above stable speeds... which is rather annoying... but still, im not complaining at a score of over 12k in '05!

Will post up scores in Hwbot threads and run e-penisMark'06 later.

Very nice Ollie, a worthwhile replacement for your venerable Gigabyte 3D1!

I found a review of the card on TweakTown, the PCB is identical but mine have a different HSF attached, which is far superior to the one pictured in the review.

I picked mine up from Overclockers.co.uk for £126.89 ($240) a piece inc. VAT

Your 12v rail is a bit on the low side (11.92) so when you load it up with SLI, I am sure it drops below spec (12.1~11.9) What brand and model do you have?

If you have any "Extra's" like lighting and hard drives, disconnecting them may help a tad.

You could also try swapping the two cards around, I bet if you look at the temps, on card is a bit warmer.

I also noticed your Motherboard Bios is 12-05, ther may be a newer one, but that probably won't have a major effect on performance.

The other thing I noticed is your ram, you may try looser timings at a higher FSB, that may give you a slight bump in performance...how much voltage are you using?

Very nice scores overall...just a few tips that came to mind if you are looking for a few more points

Thanks for the reply Necro, im not really interested in squeezing every single point out of them, im more interested in real world performance.

My PSU is Hiper Type R 580w SLi model with dual 12v rails. I disconnected a few fans and such, but most of my stuff was still connected when I benched, including four drives...

Anyway im done benching now and off to enjoy some screaming high res gaming

Nice 3D mark score....And thats one hell of a setup ya got!!

Did you get 12000 in 3dMark with both cards in SLi? I'm just surprised cos while that's an excellent score, there are guys on NotebookForums with single Go 7900Gs cards who've pushed 9500.

Running SLi doesn't mean the score will double, an extra 3000 or so points is pretty damn good. I wouldn't expect the score to go much higher than that. Still it depends on what software your suing, Dex might find theres a bigger difference between 1 card and 2 in 3d mark 06 since its newer.

Reza's right, I got around 9200 with one card in '05, double cards doesn't mean double score.

Nice 05 result. Theres something wrong with your Aquamark though, I get more (90K) with a GTO2/Venice combo... Did you do a Single card Aquamark run?

I think the Palits are only available in Europe...America is left out...but then there is still the XFX to get...(my plan)

I thought that too...mmm ill try a single card bench now.

Maybe theres some special way to enable SLI in AQ3? Though your CPU score is the one that seems low to me...

My score - 2.5GHz Venice and GTO2 660MHz/600MHz
GFX - 13654 CPU - 13421 Total - 90457

Your Score - 2.8GHz Opty and SLI 7900GS
GFX - 15054 CPU - 11068 Total - 89609

Mmmm you make a good point Zaltan, didn't get a chance to do a single card run, my house mates have bundled in my room and wanna watch a film...

Ill do some investigating and see what the problem is...

My single card 6800Ultra runs were in the high 5 to low 6k range in 05, but there may have been a little more left in there..but maxed out with ultra low ambient temps, I was able to get 12500 in SLI with an Opty 146 at 3GHZ+

So it is possible to nearly doulbe your performance with SLI, not all games will double in framerate (Though some will) 3DMARK is still just a benchmark, and does not always reflect real world results.

Yeah, I thought I'd had some basis for thinking SLi could double your 3dmark score. But yeah, you're correct in saying 3dMark is only a benchie, it's real games that matter.

Having thought about it, Necro has a point as my 3D1 in single GPU mode scored about 3.5k in '05, SLi enable bumped it to almost 7k.

So yeah I guess SLi can theoretically double scores. In my case im guessing to take full advantage of another 7900GS, it would require a CPU with a bit more horsepower, as adding the 7900GS only added an extra 3.5k or so.

Yeah, that sounds about right. Could also be that 3dMark 05 is getting a bit long in the tooth now, maybe 06 would give you proportionally different results.
