http://techreport.com/reviews/2006q2/geforce-7950-gx2/index.x?pg=1

Picked this up over the weekend. Ran me $900 CDN.

Fast card, powerfull card, and is eye candy. However..

the 7950 comes with built in Overclock settings and an option to run as Dual Monitor Single GPU per Monitor at 512mb each, or Single Monitor Dual GPU at 1Gig of DDR3. Sounds nice,right? Oddly enough,testing this on Counter-Strike: Source,I clocked 98FPS at max settings running Dual GPU mode. Then 148FPS Single GPU Dual Monitor Mode, max settings? That is to say,the 7950 ran faster at 512mb single gpu than use of both GPUs on 1 game.

Anyone else own a 7950 or any dual gpu cards, and is this normal activity?

Games need to be optimised for SLI to take advantage of it. If they are not (and believe me, LOTS of them are not!) then you will see the sort of results you have here.

I would check the Steam forums to see if other people there have managed to config it for an SLI set-up well. Some games just don't play ball with SLI at all, while others benefit from it instantly, it's all a bit hit and miss though. You'd think 'two cards, must be twice as fast!' - but games just aren't programmed like that

Good luck, that's a nice looking card!

Cheers,

Rich

Its like that huh.. that so blows. I run a AMD 3.5Ghz x64 and even thats meaningless with my games (the x64 I mean)

Thanks for reply,Rich.

Alot of wasted money.

- $108 for my A8N-VM Mobo
- $300 for my 4Gigs DDR 400Mhz Ram,
- $900 on GeForce 7950
- $400 on AMD 3.5 x64

Well,as Rich pointed out,my card is mostly useless,and as ive discoverd "x64" means sweet f**k all with any non x64 optimized game.

$2000 of "I Suck!"

Go me

You should have got a card a few notches under top of the range, you save hundreds and there's barely any difference anyway. Despite being able to run games at 2048x1024, a stupid idea anyway.

500.00 GBP = 1,035.57 CAD

Now add the cost of my 19" LCD,Audigy 2 SBL,duo 100Gig Western Digital,and we arent too far apart.

Anyhow,this was intended as a "anyone else own and have working knowledge of the NX GeForce 7950 GX2 and whats with the single GPU mode running faster than the Duo GPU?"

Which rich answerd and gave me something to research.

Feel free to lock or let sink,mods.

sick card. when configured for single monitor, dual gpu sli, it simply crushes everything in existence, and uses less power than than an ati x1900

haha first nvidia makes super card from super research for sony and ps3 then nvidia use super research to make new super cards to make sure people will still buy PC's and stuff right?

so it's like nvidia is backstabbing sony. and allthough i don't know what i'm saying i feel very cool because i just dropped my pre-pre-car-license that i have to use to practise driving, without it i can't drive with my parents :/ and that hurts. ouch.

Thats the problem im facing though Cattle! It runs faster as Single Monitor Single GPU than Dual GPU! By about 50-70FPS. Any idea? Suggestions?

I'll take sreenshots of the Counter-Strike Source report when I get home.

i think they do, but from what i've heard (the Sonys Conf. at E3 -04 and -05) they say that PS3 is the equaliant of a super computer.

you mean when running two monitors? I'd not worry about it, run your games at wicked resolutions and nice framerates (nothing too obscene, 1280x1024 max), with all of the settings in the game maxed (like I do on my pci-e nvidia 6800 ) - leave the dual monitor for apps/development and stuff like that. Just my suggestion.

The PS3 is very powerful, it just doesn't have the memory bandwidth to use its power though.

No,I only own 1 monitor(lcd flat screen) but have the option to Run the card as Two Monitors and 1 GPU each or 1 Monitor 2 GPUs. I get better faster FPS by setting 2 Monitors which only enables 1 GPU. I'll need to screenshot that too so you see what im on about.

Its SICK fast eitherway,this PC knows no lag under even the most graphically intense situations,but it eludes me that I get a higher FPS report with only 1 GPU enabled.

That's a bit bizarre. I just tested my dual GPU with a couple of my DB apps and they both run around 250 FPS on both single and dual GPU. There was no FPS difference between each modes, so why yours is dropping on dual, I wouldn't know. Mine is also dual GPU on the same card, so I don't get it.

My only guess is the mobo. I bought the mobo and card as a combo pack and apparently my Gigabyte K8N-XP mobo is the only mobo that officially supports my card. If thats the case, maybe they're optimised to work together. If its not that, I have no idea why I dont lose performance in SLI mode with non-SLI enabled apps.

ah thats right, they mention that in that article that x1 posted. X1 did you upgrade the bios, or even check the support list? Or is it possible it misreports fps in one mode or the other?

ya man,upgraded bios and ASUS A8N-VM mobo. specs are:

XP Pro x64 SP1
AMD 3.5Ghz x64
4Gigs DDR 400Mhz Ram
NX GeForce 7950 GX2 w/ current drivers from nvidia not MS
100gig Western Digital
19" DaeWoo LCD running 80Mhz
SoundBlaster X-Fi

Leaving it on single GPU and Factory Settings for now.

[EDIT]
You know? In heinsite,my GeForce was made by MSI. Maybe that has something to do with it? I wanted a make by ASUS but none where in stock.

Does that card need 2 PCI-E slots to run it, or does it mount to one, and they are linked?

Huge card. Looks small in the pictures but its sick heavy. Not exaggerating,I placed the card over the pci-e slot and the weight alone drove it into place.

It would seem,Nex,that it is mutally agreed that your random comment is not unlike the equivalent of a few friends gathering to discuss Dual GPU technology, then some random twit squat in the middle and took a dump,then looked at us as if he just contributed some deep intellectual feedback to the discussion.

Got my ASUS NX GeForce 7950 GX2. Same odd results. Not bad,just not what I expected. You guys think,maybe that the 7950 is immediatley splitting the data between both gpu's as opposed to using one gpu to its 512mb capacity then using the next,and this is the cause of the slight dip in FPS,and thus why when I have single GPU enabled,there is a slight spike in FPS?

As Mr Davey said
Quote: "I would check the Steam forums to see if other people there have managed to config it for an SLI set-up well. Some games just don't play ball with SLI at all, while others benefit from it instantly"


I'll spend lunch sifting through the Steam and Nvidia forums. I havent tried any Benchmark software yet. Suggestions?

Its sad to admit,im more intrigued with just how far up his arse Nex had to reach to pull that comment out,than I am with my Dual GPU research.


Ok,as per Richs advise,ive done some more research. This following comment from http://www.pcper.com/article.php?aid=256
Quote: "In games that are heavily CPU bound or don’t support multi-GPU rendering modes, the lower clock speeds of the 7950 GX2 will mean it will run slightly slower than the 7900 GTX and more inline with the 7900 GT"


Think the key words in that are
Quote: "don’t support multi-GPU rendering modes"


I never considerd that. The fool I am. Rich DID clearly suggest that alot of games dont support Dual SLI which I should have equated with Multi-GPU. I feel infected by Nexs infinite failing logic.

Hey now,not like im posting just to slam Nex. Im following up on my own posts and responding to others nex related posts. I am staying ontopic.

im finding alot of Benchmark software but nothing specific to Video. I want to benchmark with Single and Dual GPU with varied Overclock settings and without.

Do me a favour, don't become a physist.

Ye gods, don't you try either.

Of cause weight and mass affects how much gravity affects the object, weight in a measurement of an object under a gravametric field, and mass of cause relates to the density if that object.

What you both ment to say is that "size" doesn't affect how much gravity affects and object, mass does, after all, a lump of cotton will never weight the same as an equivilant sized lump of Urainium.

-------------------------------------------------------------------

Back onto this card.

It's definately a beast of a thing, I imagin most of the weight comes from the cooling fins and fans.

Are the cards just SLI'ed together or have they been setup at the hardware level, with special drivers, to word in tandum? So the computer really only see's it was a single graphics card? Cause if it's not seen by the system as an SLI'ed device then it's really not SLI'ed is it? Yes it's basically two boards shoved together, and made to work together by a manufacturer, but it still uses just one PCI-E slot so it doesn't have different PCI intrupts to slow it down, and of cause it doesn't have to deal with one PCI-E slot being x16 and another being x8 or x4 etc.

Regretabley,I lack any engineering knowledge of the 7950. It does indeed come with a specific driver which regretabley I can not install on XP x64, and so I used a driver from nvidia for x64 GeForce. The card has 2 ports on it either of which can be used for single monitor,single gpu mode.

no offense Nex,but I try to ignore that picture as much as humanly possible. It really is gimp =/
