Whats the biggest F@H GPU video card as far as PPD ?

I have 3 X1900Xt cards. They do 1000 PPD, and I have to loose a second CPU SMP client, so its not worth it, besides they produce a lot of noise and heat.

So I was thinking about how the new cards do. Please let me know what cards are the best, and what PPD.
 
Hi Markfw900

The EVGA 8800GT O/C card (which I have o/c'ed some more) is pumping out about 5,200ppd in a Antec 900 Midtower having the following:

-GO 6600 Intel Quad (o/c 2.7ghz)
-Gigabyte 35 chipset mobo
-8 gigs of ddr2 800 ram
-600w OCZ PS
-Zalman 9700cu CPU fan
-Vista Ultimate 64bit o/s

I also have 2 SMP's running as well (although the 2nd one is only doing Uni cores - will try to take care of that this weekend - thanks to Cutthroat and the rest of the gang for making ANY crunching possible on my 2 boxes after those geeks from Stanford uploaded those 6.2x cores!).

The GPU2 is doing about 1min 17sec per wu percent.


On a AMD AM2 Brisbane box I have a Gigabyte 3870 vid card (was in the quad box until I got the 8800gt 2 wks ago). Finally able to get GPU2 to run on this after this past weekend's disasterous core upgrade from Stanford. Could not get it to run under Systray so I tried Console and that worked (whew!).

O/C'ed the video card prior to running GPU2.

It is doing up to 1,400ppd (around 1min, 45 sec per percent of wu)

is that 512 meg or 1 gig ? O can;t find an "OC" version on newegg. Could you link to it ?
 
The best price/performance ratio would be the 8800GT probably, The best performance would be a GTX280, but you don't want that on a system you aren't gaming on.

If I were you, I'd just buy the cheapest 8800GT for folding and overclock it yourself.

mem=512

At Denithor's thread (listed below) he stated that it seems that the size of the memory (256 & 512) did not seem to have any effect on the ppd for this specific type of card. When I o/c'ed the card (see below) I changed the mem clock values but it did not show any advantage in increasing or decreasing the mem clock speed on the ppd results.



Here's the link:

When I first installed the card (prior to the core upgrade release) the card generated around 3,700ppd. I was rather disappointed with this since another Thread:

http://forums.anandtech.com/me...ht_key=y&keyword1=GPU2

by Denithor showed my basic card description as producing 4,400ppd to 4,800ppd (o/c'ed). I thought something was wrong with the card so I d/l'ed latest drivers from EVGA.

This did'nt do much to my ppd (Be warned: you need to d/l CUDA from nVIDIA for the card to process F@H W/units) so I d/l'ed the RIVA utility to see what my card was doing "under the hood" (EVGA also has someting similar on their site as well and I read somewhere that there is one from ATI as well that can also be used on an nVIDIA card).

I ran RIVA and under the utilities gave me a graphical representative of the different cores and the fan's info as well. This was very informative since all of the values of the card was showing at the low levels that the card ranged to.

I was a little hesitant to o/c since the card states that it is o/c'ed (at least, o/c'ed over it's standard 8800GT specs) so I took the plunge and adj. the settings.

I first raised the fan speed to 75% (it was at 25%) and the GPU core temp came down from 70c + to 50c range (was not running the GPU2 core at this time-btw, I didn't notice any increase in sound from the fan when I did this). I then adj the clock, shader & memory speeds. When the PC was stable at the 740 core clock speed I ran GPU2 core. My ppd values jumped from 3,700 to over 5,200-5,400ppd (At least when there are WU's available form Stanford - this doesn't happen too often, thank goodness!).

I was a very happy cruncher since this value is above and beyond what Denithor's reported for this kind of card. I've been running it 24/7 ever since (except for that damnned 6.2x core upgrade fiasco!).

Looks Interesting, Markfw900

I tried to go above the 740 core clock speed (did 2 adj - each incremental increase was a value of 10 so the last one was at 760 core clock speed. It seemed ok at 750 but at 760 items started to disappear from the desktop and then it crashed) and unlinked the core clock and shader clock so I could raise the core clock only since I read somewhere that the shader is not what is needed to crunch.

I also increased the fan speed to 85% and the report from the graphs shown that the core temp didn't go above 60c so I don't think that temps was the main cause of the instability that was observed above the 740 core clock o/c.

It looks like it has better coolinng, and wouldn't that OC better ? above the 650 factory ? above the 740 you got ?

Yep that's the one I had my eye on for the same reason: better cooling.

Let me know how it works for you!😉

Rats, did I forget about the Radeon 4850 ? how does it compare to the 8800GT ?

IIRC, Bryanw1995, has a 4850 now and he has stated in a couple of threads that is doesn't do any better than his old 3870.

BTW, the 3870 does around 2000-2500+ PPD....

 
Ah jeez, you already ordered, the 9800 GX2 is the best single card for ppd. Slightly overclocked it does 10k ppd. If you do decide to change your order, the EVGA version is 285 at the egg with free shipping.

Really? I thought someone posted it was only doing about 6,000 PPD...at stock speeds, I believe...

It's not configured correctly then, I'm doing 9000+ at stock right now with the one I just got. Use the 177.35 drivers and you run dual GPU2 clients, one on each gpu core.

Well, thats great new input. After researcging I found many comments like this that make me worry(this was one, but several had the same comment):
Cons: too many cons to list.. 2 8800 GTS's can out perform this card and stay much MUCH more cooler while doing it. Its very overpriced and is gigantic. Once again seen multiple reviews and this thing gets very warm and hot, i cant stand hot gfx cards! thats my biggest pet peeve! why buy a inferior design that heats up and cause probs in the long run, doesnt make sence, they should of though of better cooling. Not getting my money, not with that same 256-bit interace and weak cooling shareing a single heatseant. BOOOOO!

So I think I am happy for now. For that price, I can get 2 8800 GT's (130 after rebate)

Edit:, and I have 4 boxes to put these cards if I want to. They are running the wimpiest carfds I can find to save power, X1300 ati and 6200 le nvidia.
 
Well, let me toss in my two bits. The best card right now for ppd is the GTX 280 which cranks out about 7k ppd at stock speed by itself. If someone has figured out how to run the GPU client on both cores of a 9800GX2 please notify Gravity because he's not having any luck with his.

I have three boxes folding with the GPU client right now, one on an EVGA 8800GTS 512MB and the other two on EVGA 8800GS cards. I haven't gotten an accurate ppd from the GTS yet but the 8800GSs run 4320-4800 ppd (each) consistently with a moderate overclock (650/900 versus 550/800 stock).

I also have a Gigabyte 8800GT 256MB that cranked out 4800-5280 consistently (factory OC of 700/900). That one is going into my mom's system this weekend (rebuild) so I can get some more points.

Just as a note, if you are looking to replace all three of those x1900xt cards for your farm and funds are a bit limited you should consider this deal: EVGA 8800GS for $64AR. (Stolen shamelessly from the Hot Deals section.)

See the 3rd and 4th posts, the nvidia_g80 flag should let you do it without having a monitor hooked up to each video card, but I've been using a KVM, others are using resistor modded DVI to VGA adaptors. The GTX 280 is probably the worst investment for PPD per dollar and it can't beat the 9800 GX2 in PPD when you properly configure it to run two clients.

Which is fine, we're just talking the best single card solution for ppd. If you have multiple PCIe slots then go with what best fits your setup.

I'm on it. Good project for late night tonight.

Thanks all!

Got my 8800GTS 512MB finally (took a kid on eBay like three weeks to get it shipped). Clocked it up to 750/1000 and it's cranking about 5500 ppd right now. Plus I can play WoW fully maxed while still pushing the GPU client full steam. And it only cost $110 (after Live Cashback). So I'm pretty happy with this purchase.

If you opt to get two more 8800GTs I think you'll like the ppd increase overall. You should become a folding monster at that point.
