just started folding and had my GTX260 running for the last 4 or 5 days. my GTX295 has arrived today but having put it in i am only getting a marginal increase in speed at folding.

I understand that SLI'd cards need to be un-SLI'd ,but didnt think this applied to the GTX295 being all in one card?

help pls! so i can really get these points going for the team!:)
 
You need to un-sli them in the nvidia control panel - folding cannot use sli cards even in double card form. It is the same with the 9800GX2, as both cards use a form of internal SLI. As i say, there is an option in the nvidia control panel to turn sli off. You then need to install two of the console clients (unfortunately, the graphical clients wont work.. unless thay have changed something!) in two separate folders eg C/folding/gpu1 and C/folding/gpu2. Run the clients with the -configonly flag the first time and change the advanced options. There should be an additional client parameters option, and in here you need to type -gpu 0 for one client and -gpu 1 for the other. You also need to give them separate machine IDs (another option in the config). You should then be able to start the two clients folding on the two separate cores for double the points!
 
i was hoping that wasnt the case. in the multi gpu guides in implies i need two screens and need to extend them accross, is there any way around this as i dont have two screens?!

i could get a VGA to DVI and plug that in my monitor as another input. would that work? problem is i dont want to extend the desktop on to dead space that i wont use.

If you have a hunt on the Folding Forums, there are links to adaptor plugs you can make to fool the graphics card that a monitor has been plugged in. You can even do a quick fix of plugging resistors into the monitor connector directly IIRC. Adaptors are also available to buy ready made.

You could just plug the other output into another input on your screen - that is what i did. You do however have to extend the desktop if you are on vista. Its a bit annoying, but thing do not tend to open on the 'second' screen, and it does giv e you a convienient place to hide the F@H console windows. I think its a bit different on xp - i do not think you need to have an additional 'screen' plugged in, although this may have changed. You can make some 'VGA dummies' - essentially just a vga adapter with some resistors shoved into some of the ports that will trick the pc into thinking that there is a screen attached to the card. Some people have done this for folding, although i personally have not.

Edit: ^^Beaten!

Oh i wish i had some of these cards. Would like to know when you get them up and running what is your PPD from it.

Are you running vista ?

running vista.

seems to be about 8000ppd off the one core clocked at 650 /1440 /1100. might be able to tweak a bit more out of it but 3dmark06 crashed when at 690 /1480 /1200, so backed everything down a bit, only had it since yesterday afternoon so havent played around much yet.

might send this back anyway as its noisier than my GTX260 and that was the loudest component in my PC as it was and i want my pc to be as quiet as possible. also not massively impressed with the games performance - its better just not really that noticable. might swap it over for a 285 as it will be just a bit boring going back to a GTX260 despite it being perfectly good card!
 
Well that sucks.
I still would not part with the card because i found it to noisy. I would suffer it to play my games as the way they should be played "full detail with hight screen res"
 
i have a 24" screen at 1920*1200. its only really crysis that cant be played with everything maxed out a few other games you might need to drop the AA down to 4x or 2x but even so. i want my PC to be quiet so would rather give that little extra up. :)
