My GTX 275 co-op is doing about 13k ppd with the 494's. Running 617c 1548s 1008m on the 275 core and the GTS 250 is stock. So you're the other guy that bought one.

You've got to try to oc the g92. Mine is at 1,200v@stock, and do 2000 shaders. Really weird g92, 192 bit memory, 384 mb ddr3, pretty high vcore...

For the damn 494, i'm stuck to 7200+4300 ppd. No matter the clock.

To TexBill, my gtx 460 at 900/1800 is doing 15500 ppd on 9xx wu's. How does your gtx 480 is doing 16500 ppd? Am I missing something?

What do you mean?

 

[TeXBill]

The GTX460 only has a 192 bit memory interface and 336 stream processors.
The GTX460 1GB has a 256 bit memory interface and 336 stream processors.
The GTX480 Has a 384 bit memory interface and 480 stream processors
Am I right on this logic Buck?

 

[Feänor]

I mean that with 336 cores i do only a thousand or two ppd less than you with 480 cores. I think i'm missing something as an increase of 42.8% in the core number can't increase of only 14% in ppd production. Add the fact that you've got a decent oc on the card (so do I!)...

GPU3 does not scale according to shader count(i.e. GTS450).

So what actually makes the difference between the 2 cards in PPD, besides what I put in my previous post?

 

[theonedub]

It was my guess that PPD on the GPU3 client scaled logarithmically with shader count, but its only a guess. Looking forward to what Buck says.

Getting ready to switch all my rigs over to Win7, so I've got to make 6 dummy plugs. Radio Shack only had 2 packs of resistors:shadedshu, so I will do the 2nd rig next week when the rest of my Fermi cards arrive.

 

[mlee49]

Buck I'm gonna need to make a dummy plug as well.

Anyone know where I could just steal a couple resistors from? Other than RaidoShack?

If you just need three PM me your address and Ill throw some in an envelope for you

Way to step up theonedub!

I think the short answer is: "we don't know." GPU3 is still new and Fermi is new. Who knows, maybe Nvidia will release a new driver that will turn the GF100's loose. Before the 400 series, it was about the # of shaders and to some extent, their clocks. With the 400 series, it seems to be more about the clocks.

Thanks for the offer, I've got access from my school though.

I'm wondering what I can just tear apart here at home and use... humm.... maybe an old stereo or something.

 

[headshot119]

Any cheap battery or shaver charger should have a couple you can use if you don't want the charger.

Ok, got her up and running. Used FahtrackerV2 and that software is slick! I'm using a server fan to keep the cards @ 45c. That fan is scary to stand in front of. The entire rig is only pulling 550w. It used to take over 1300w and 2 rigs to generate this kind of ppd. I'm looking forward to setting up the next rig in a week. If fermi's get cheap enough, I may set up a 3rd rig like this! Now I just have to buy some more GTX460's.

Got to agree Buck, Tracker makes it sooo much easier when setting up a new rig.

Hopefully new members can install Folding@home with little trouble and make the jump to helping so easy.

 

[hertz9753]

Looking good Buck. Is that a server board with an AMD 9850 installed?

Nah, that's a venerable MSI K9A2 Platinum. I've got 3 of them right now(had 5 at one time). Great board, but it's limited by the SB700 series chipset.

Yeah they are the folders dream

Got a couple myself, but unfortunately they will have to retire soon, to make way for x58 boards

Check with me before you get rid of them. They are a great GPU workhorse and I feel Fermi has a promising future.

BTW, I've got 60%+ CPU usage from the 4x GPU3 clients, so I'm not gonna bother running SMP2.

 

[oily_17]

That seems high for the 4 x Fermi..... I have only 2 running on my i7 rig but they only use about 8% of the CPU.

Anyway you PM (will have shortly)

looks nice Buck, question though

do you use that 4 pin molex? the one above the pci-e slots, im guessing its to feed extra power?

btw, the board supports new x6's hint hint hint hint

remember if its an older phenom /athlon the usage cannot be compared to an i7

Thanks for the light. I would conclude from those numbers, that over 850 mhz, shader count does not have a huge impact. That's the whole point behind gtx 460 folding : high clocked not so high number of shaders. GF104 = insane ppd for the $.

If you have already one rig of them, and if i understand correctly, will upgrade two other, all with gtx 460, that's gonna be something like 150000 ppd excluding smp...

 

[oily_17]

Yeah completely right, bit of a brain fart there ....just didnt think it would be that high.

Never really checked what the impact was on the CPU with all the GPU's running

 

[popswala]

If anyone upgrades their 460's or know someone selling. I'm looking to buy. I'm a fellow team folder and cruncher 24/7. I need to get some better folding and be able to game better since my 250's are crapping out on me.

Anyone hears or see's anything. Hit me up. Thanks.
