GTX 700 series folding & PPD.

Hi.
Is anyone folding with GTX 700 series cards yet? Is folding supported on these cards yet or is it too early for that. I know from reading the forum that it took some while to fully start supporting the 600 series of cards. The cards seem to be coming down in price now, so I was wondering whether they would be a good option. What's everyone views?
Cheers.

The 600 and 700 are the same architecture; Titan has DP. Should be supported just the same.

 

What's DP?

 

Double precision or FP64 http://en.wikipedia.org/wiki/Double-precision_floating-point_format

my 660 gives upto 55k ppd
my 660ti gives upto 75k ppd
my 760 gives upto 73k ppd

 

GTX 700 series is supported, but perhaps not the new GTX 780Ti yet.
You need to be aware that on some 7 series cards there is a TDR issue with certain nVidia drivers which has the effect that, when Folding 24/7, after 36hrs, the PC can hang. So check up on the driver version first.

 

also any newer driver than 326.80 the ppd will be halfed i use 326.80 and no tdr effects with mine

what cards are you folding on docjonz

 

Is the driver issue just on the 700 series or does it affect the 600 series as well? I've just started folding with 2 x GTX680's with drivers 327. something I think.

Do I take it then that Double Precision floating point format is good for folding then?

yes but 327.23 are ok too

Single Precision is on other cards but look at point 20 and 21

Currently running GTX 780's with a modded 314.22 nVidia driver.

 

cool thats a good output

 

Do you think that there would be much of a different PPD between a GTX680 and a GTX770 as they seem to be a pretty similar cards on the face of it except for the memory speed? Is memory speed important for folding ability?

Just upgraded to a 760 and changed from the latest driver back to the 327.23, resulting in an average of about 65k PPD works fine

 

That's a good work rate for an fairly inexpensive card. Did you suffer from reduced PPD with the latest drivers then? People are saying that is s problem with 700 series cards or GK104 chips

 

Hi petaflops
Yes, I did suffer quite drastically and the boys on here advised a rollback and it did sort things out. Depending on the way the calculator works on each individual section of the unit being processed the PPD shown varies considerably, between 50k and 78k. I am only using the Beta flag, and am folding on all 4 cores of the CPU, and have not allocated one to the GPu.

 

Is it worth doing an experiment and seeing what happens to your PPD when you allow the GPU one core of your CPU? It would be interesting to find out if it really makes a noticeable difference. I've been folding on a couple of MSi GTX770's for a couple of days now, and they are giving me a steady 90K PPD per card with the Beta flag and one core per GPU. Has anyone got some GTX780 figures out there? or even the GTX780TI, though maybe a bit early for that!

All my GPU's, in the sig link, are GTX 780's ....

 

So they are all doing about 120K - 125K PPD. Is that about the same as a Titan or would that do more. Not that I would even be tempted to buy a Titan card as they seem a huge waste of money for what they are.

 

Titan's will do more .... (apart from putting an unnecessary hole in your pocket )

 

About how much would a GTX Titan do per day? Presumably the cost/PPD would be fairly low compared to other cards due to the very high price of the card in the first place?
