Best _single slot_ card for F@H

Want to get the best possible single lane card to go in an E-350 rig's X4 lane.

At the moment there's a 7900GS in there, but it can't fold and it doesn't play games too well either. It's just as well I can't fit a dual slot card though as I think most dual slots would be bottlenecked by the E-350, which I had running 1.76Ghz yesterday but crashed after about 15-30 minutes folding so I'm just running stock everything now.

I was thinking a 450 single slot as there isn't any 550Ti single slots I've seen - should I wait for the 650 or 630 if such Keplers arise?
 
Probably best to wait for the kelpers.

The MSI 8800GT OC I had was single slot (and quiet) but I'm sure you can get better than a 8800GT in a single slot for folding.
 
better wait and see what kepler does, as of right now they are horrible folders. the 7970 had 3 times the compute power of the 680, and the old 580 totally destroyed both of them!

I don't know if future driver issues will fix this or kepler was never designed to compute, but I think it is strictly a gamer's card.

I know right! Been looking about on that very subject today and it gets worse PPD than one of my 5870s!

We don't know if kepler is a horrible folder yet...folding doesn't work at all. PG should have an update in the next few weeks to support the card, then we will see what kind of performance it has. Luxmark isn't exactly the same as folding. Luxmark is an OpenCL bench while nVidia cards fold using CUDA. They are similar yes, but not the same.

I was reading on OCN for info can't remember exactly how bad but I saw the 7970 getting 8.5k PPD @~1.1Ghz I think and Kepler was as you say poor in OpenCL, think there was some mention of CUDA performance being low too though - can't remember seeing an actual 680 V7 shot though - though I might have, will have a look again for it.

EDIT:

Yep it was just a screen of the Kepler irrecognition with Fermi, doesn't work at all yet (not immediately as an end user would want and by the time it dawns on them to force things as mentioned on EVGA, they will have updated things anyway - we hope).

Same thing when Fermi came out, it was a few weeks before they could fold. I tried running F@H on my 680 and it was a no go. Nothing happens at all.

I did consider a dual GPU single slot Quadro but they aren't efficient for F@H - waiting on Kepler now then. Not wanting to go WC'ld though so a single slot 680 isn't an option. Maybe there'll be a single slot 660Ti

The thing is I only have the one lane due to form factor, so can't just swarm the board with 430 OCs

I'm sure they will get the 680 sorted out. It has 4 times the exact same CUDA cores as Fermi, but the new architecture runs them 1:1,where as Fermi ran them 2:1.

There is no reason the 680 couldn't fold, but the math says 4x the cores 1/2 the speed = a wash

but the 680 has a higher clock so you should see a difference of 1/2 the clock rate over Fermi in folding once they got it all working.

but the topic is single slot cards and I don't see them making a single slot 680 any time soon.

so my suggestion is to wait and see what that do with the lower end cards, not directly compare the 680 for his current application.

Nvidia, may need a whole new batch of low end cards to be able to compete with what AMD is already releasing. To get theese new GPU's the either have to wait for partners to start binning 680 GPU's and get some that are slightly off to make 670s and 660s.

Or Nnidia could do a quick turn around die shrinkage of Fermi where they shrink,say a 560Ti down to fit the roll the 450 single slot cards currently fill.

We just gotta wait and see what the market does. but I'm hoping they do shrink current cards to fit the lower end market.
 
Sweet find! I wonder if they are already shrinking the dies on the older cards?

I know they say the same 40nm GPU but the power seems down alittle and it's slightly overclocked!

Never knew that existed!

Should've said though, the card will be running off a 250w PSU with only two free molexs for powering it/ convert them to one pci-e 6 pin. The E-350 only has an 18w TDP though, so up to 238w max for the card.

Galaxy do (or did) a single slot 550 Ti with a single PCI-E connector. Although from what I have seen, it;s not a truly single slot card as the heatsink hangs down a bit.
