Can anyone please helpme, i have a EVGA 7950GX2 and i have some problems with performance, but this suppost to be one hell of a card. well does anybody here know by experience what drivers are the most suitable for my 7950GX2 for playing games. and also what software can i use to see if the two cards are actually running together on SLI.  i ask this because my card only shows 256bit and 512ram as i thought it will be 512bit and 1Gb ram??? does this mean my card is only using one card not two, also when i go to nvidia control panel the multi gpu mode option does not show.


thank you guys

I think i've found the problem if you're trying to try use two EVGA 7950GX2's on a ASUS M2N-MX SE motherboard im afraid to say that your motherboard doesn't support SLI, If you're trying to use a single card updating your forceware upto 169.21 would be a good idea the drivers are listed on your other topic (20603)

Good news i manage to find the right drivers from XTREME-G drivers and my crapy ASUS M2N-MX SE is letting me run my EVGA 7950GX2 on SLI mode without updating BIOS and i just been playing Crysis in midhigh graphics setup with antialiasing on as well and it rocks, no lag and nice graphics. but i notice after the game the cards get Very Hot one GPU at 75C and the other GPU at 79C wow. is this normal to get this hot for this cards or any of the new cards? i'm wondering even though i have two 80mm fans running at the back of the case and two 80mm on the case window facing directly to the two cards and still this hot.


Cheers,

Lew

I hear those GPU's generally run pretty hot. Any chance of getting a picture of the inside of your case so we can see your cooling setup?

"79C wow. is this normal to get this hot for this cards or any of the new cards?"

Yes it's pretty normal for High End cards to run real hot with the 8800 Ultra being a prime example you might want to invest in some sort of cooling system or if moneys tight you could do a custom case mod and make a ducting from a fan straight to your gpu which would help with your current heating problem if you're interested in doing this there may be some tutorials if you google it or if you can't find anything ill be more then happy to show you how its done =)

Here is a picture of my case with the current cooling setup, i have fan controler for the four fans to crank them up to full speed when i'm gaming. did you guys think this GPUs are running to hot? I customised my pc myself but i just did not researched. Bugger.

Thanks

I did not know firefox does not allow me to copy and paste into this notes, i got the picture but i cant inserted here.

My friend 79C is hot but for what card you're using it isn't what id call a major issue, maybe for long time gaming sessions? just make sure you keep an eye on your GPU temperature. Anything over 90*C is unacceptable. But do remember less heat usually equals better performance espically when it comes to OverClocking. If i was you id play crysis for a few hours and have a application running in the background recording your GPU temp thoughout the gaming session if it does indeed go beyound the 90*C mark then you'll seriously need to think about upgrading your cooling setup.

If you'd like to host the image temporarily, you can upload it here:

It'll give you back a link which you can dump here for us to look at.

Creating a cooling duct in your case straight to your GPU's is a good idea also, Google it and you should find some helpful information.

Hi friends, thank you for your recommendations i do have a cooling duct exaust thing that can be attached directly to a 80mm fan but the problem is this cards are so big that the gap between my window fans and the card is not much and i don't think the cooling duct will fit, the problem i see is that behind the card i can't place the exoust cooling duck because no room card to long 9inches long. and i think the heat is due to the cards been placed so closed together so the only direction i can suck air out this
GPUs gap is phasing from the window.  friend 3nvy could you please send me that link and you can all see the case and maybe give me some advise as i have extra perpex plastic glass board to make a new window if required.
I have though about placing my fans outside the case to provide more space between cards and window? or maybe i have to adapt a home fan on to the side of the case but that will spoil the look and the noise will be not good.


thanks


Lew

I have seen MASSIVE fans before that almost take up the whole side of an ATX case im not sure what mm it is but installing one of those would be a last option in the war against your heating issues since it will make your case look ugly if you use a case window, One plus side to this is that it would be a hell of alot cheaper then installing watercooling.

True Kommisar, i think big fan fix one problem and creates anotherone but cheaper that watercooling.
i'm looking at the case and think that if i put four castor wheelies under the case it make it easy to move and I can place a fan under and hook up the cooling duct ??? but i will only cool one side of the card. I want to over clock this monster and unleash the beast it can overclock significantly with proper cooling $$$$ according to reviews online i can gain significance performance not that i need that now as is running Crysis nicely.
I have also considered some crazy modds
1 using a vacum cleaner 'small' and putting hose directly between the cards.
2 spliting the cards with spacers maybe but the sli conector can only go so far.
3 Use dehumidifier setup but that is insane. but i seen some crazy stuff on the web.


thanks,

Lew
