8800 gs

lopkinfop · 2 Jul 2008 at 20:04

does anyone know what the PPD are like for the 8800 GS, they now sell for less than £60

Cool graph. Probably not worth trying to fold on my 8400GS.

You could try 1 WU just for the hell of it.
I wonder what impact the CPU has on the ppd? Did I read you need 1 core to feed the GPU?
Certainly put my 900ppd on SMP to shame

I know, I'm tempted to do it just for the hell of it, but means shutting down the VMs and SMP clients and getting CUDA/drivers. Bit of a pain in the derriere all told. I suppose I should stop being lazy.

Might do it over the weekend.

It matters more on AMD cards. For nVidia cards < 20% CPU resources. And that's a very conservative estimate. I don't quite get it myself as a few months ago they were saying the GPU would be CPU limited, and that even the fastest current CPUs couldn't feed the cards fast enough. They must have made one hell of a breakthrough in the software. :confused:

Funny you should mention both those. I'm running a 8400GS in my Vista rig, and I bought a 8800GS from the MM on Monday. I'll test the client on the 84 tomoro, and I'll do the same with the 88 when I get it.

would the 8800gs be much of an improvement for games over a 1950 pro, if so i might have to get me one for the time being untill one of the newer games i want come out

Cob · 3 Jul 2008 at 11:59

I think it's similar to the 8800GTS 384mb card, so it'll certainly be a step up from the X1950 Pro.

Tho I do know **** all about graphics cards tbh.

Cob · 3 Jul 2008 at 12:39

Well I just tried it on the 8400GS and I can't get it to work. Downloads work and then errors saying that it couldn't find cudart.dll. I'm using the 177.35 CUDA drivers.

Hi Cob - there's a thread somewhere on this forum that mentions this problem & how to fix it. cudart.dll gets put in the wrong folder & need to be moved to ?? [program folder? can't remember]. Sorry in a hurry I'm sure you'll find it or someone else will know where it is.
Good luck

Cheers.

Seems to have started ok this time. I'll let it run for a while and see if it's worth it.

So with a 479 pointer, I'm averaging 510 ppd. Not worth it with an 8400GS IMO. Hopefully I'll have my 8800GS tomorrow to test.

verbal · 4 Jul 2008 at 14:57

Hmm, I have a 8400GS at work I could borrow and a socket 939 chip/ram/mobo at home. So basically I could get 510ppd for just the cost of the electricity.

Did it look like the 8400 would meet the deadlines Cob?

Cob · 4 Jul 2008 at 15:10

With that WU it certainly would have.

I'm now going to run alongside the 4 linuxSMP clients to see whether they affect each other much.

Cob · 4 Jul 2008 at 18:18

Ok now with 4 linuxSMP clients also running via VMWare -

[14:11:47] Completed 3%
[14:11:48] Starting GUI Server
[14:25:34] Completed 4%
[14:39:07] Completed 5%

[15:06:01] Completed 7%
[15:19:30] Completed 8%

[16:00:01] Completed 11%
[16:13:30] Completed 12%

[16:40:36] Completed 14%
[16:54:09] Completed 15%
[17:07:46] Completed 16%

So it happily runs with CPU usage already at about 100% (tho with Vista you seldom get 100%).

I think I'll actually keep it running. The card only hits ~60c and won't be drawing much power, and the extra ~3,500 points per week can't be sniffed at. Tho I'll have to see how it runs with different WU's.

theheyes · 4 Jul 2008 at 20:39

500ppd isn't that bad tbh, considering a whole PS3 knocks out about 900ppd. I'll dig the wattmeter out if I get round to installing it on my 8400.

my 640MB 8800 GTS is giving me 3,600 PPD according to FAH.
(CPU is an Athlon 64 X2 4600+) btw

FAH is reporting some crazy readings for my 8800 GTX, but the PPD value for that is quite a bit higher in the high 4,000 range. (CPU is QX9650, percentage load is 5% on one core)

That is some serious PPD there from just one graphics card. puts my 1950 pro to shame.

lopkinfop · 5 Jul 2008 at 10:20

i think i used to get 600ppd from my 1950 pro

PiKe · 8 Jul 2008 at 12:19

What would a 7100GS give me?
