Hi Everybody!

News from mmaakk:

I did replace 2 ATI cards (2x HD 3870) from one of my PC's. I bought 2 new cards - nVidia Palit 9800 GT 512Mb DDR3. I was hoping to get at least 6K PPD each, looking that I'm doing 6.4K PPD with my 8800 GTS G92 with OC, but didn't work out well. The 9800 GT at stock values - 600/1500/900 - was getting around 3.7K PPD. Than the nightmare started when I tried to OC the cards. I found some reviews like "Gigabyte 9800GT 787/1863/1075" so I went for it!!!

Resuming the story... my actual values

Card PCIe 1 = 684/1579/900

Card PCIe 2 = 714/1618/932

PPD: 4,411.91 per card :shadedshu

I was always an ATI guy. So I can handle OC, BIOS mod, etc... very well. But with nVidia the only tool I'm using is RivaTuner.

PLEASE I NEED SUGGESTIONS TO A BETTER OC FOR THE 9800GT. EVEN GPU OVER VOLTAGE IS WELCOME IF NECESSARY.

I got so pissed with all that, so just to get things better I'm folding now with my Gamer rig too (2x HD 3870X2). FahMon says 22K PPD total - check attached pic.

Mmaakk, I want to start be saying thank you for you efforts and contributions to TPU! I have the answer to your problem. GPU2 is very shader intensive. In Rivatuner, you must un-link the shaders from the core in the o/c'ing window. You want to take your shaders into the 1800/1900+ range and leave the core in the low 700's. Memory is not as important, but a small boost won't hurt(850'ish). Fiddle until you find your highest stable overclocks. Good luck and watch your PPD climb.

Big News for GPU2 - 10% Boost to PPD

In case no one has seen these yet there has been new cores released for both GPU2 clients. The threads discussing each of these on the F@H forums is below.
*This is a real-time 10% boost for Nvidia cards.

*ATI 4870x2 can now fold under both cores in XP only.

Nvidia 1.15 http://foldingforum.org/viewtopic.php?f=52&t=6203

ATI 1.17 http://foldingforum.org/viewtopic.php?f=51&t=6199

It's very simple to upgrade the core:

1. Shut the client down.
2. Open the F@H GPU2 program folder(not the shortcut's).
3. Find the "F@h Core 11" file and delete it(ATI users should re-name the core instead of deleting, due to possible issues).
4. Re-start the client with the usual shortcut and the new core will be downloaded automatically.
5. Sit back and watch your PPD increase by 10%.

Please leave a thanks if this helped you.

 

[xazraelx]

=) Thanks.

I wouldn't have checked that for a while o.o

Also...how far can you push shaders....I'm still only getting 2.8-2.9kish out of my second card, a 9600GSO. I'm told they can easily hit 4.5k at the very least - I think it's partly due to being the second card (not sure why), and partly because the shaders are so low (right now they are at 1534. How far can I push these without bricking the card /// getting driver errors?

I can run my 9600GSO's up to 1800+ on the shaders, but you must un-link the shaders/core in Rivatuner/EVGA Precision. Core should be low 700's and memory @ 850'ish. Just tool around until you find your highest stable shader o/c.

I didn't think it had to be "stable" to fold?

 

[BUCK NASTY]

Stable as is the client not returning "early end units" or "unstable machine".

 

[mlee49]

Ok so I just got my new build put together and I want to start folding! I dl'd the core for my cpu and then I started working with the gpu client. Seems only the gpu client is at work, is that the way it's supposed to be? Can only one client be preforming at a time?

If I'm missing something about how I can fold with my cpu and gpu at the same time please someone point me in the right direction.

And super props to Bucknasty who has been leading this effort! Great Job Man!!

I'll load it up tonight after work...
Got my cpu up and folding
I still need to get my other vid card going, just not enough hours in a day

Thanks Buck_N for the heads up!!

I already update the files, around 1 hour ago, but my PPD numbers still the same. No problems for XP but my Vista PC didn't like the new core 1.17. And the process that was 84% done is gone!

...starting @ 1% again

About the new cards I got Palit 9800GT (fu__ing cards!!) will return to the store next Saturday and get 2 8800GTS G92 just like the one I already have and roll @ 6K+ PPD!!!

Will spend some quality time now figuring out about the 2 cores running for my pair or 3870X2.

A BETTER PERFORMANCE FOLDING IS ALWAYS GREAT NEWS!! MORE WORK DONE TO OUR GOAL - SAVE THE PLANET AGAINST DISEASES.

Does it show the new core in the work log when you start GPU2?

+1 on the 8800GTS. I just ordered a re-certified EVGA 8800GTS G92 off the Egg today for $109.00 + free shipping. Here comes another 6700PPD

On another note, I have found a home for my rigs. At work we have a server room that has ample space/electrical and plenty of air conditioning to battle the heat of these cards. I got the OK to set up 4 rigs there and the elec is free! Only downside is I must provide UPS back-up for the rigs in case of power failure. This may cost a little bit of cash considering the amp draw of 4 rigs. I will work on it and post pics when set-up.

I was looking at my Folding and it says I am folding for more than one team???
how can I fix that??

Yes it does!

1.15 nVidia

1.17 ATI

Go into the install DIR, and delete the client.cfg (iirc) file...that will delete your setup, login, password, machine id, team number info...so you'll have to re-setup your clients...but that's how I've done it before...now I type 50711 in my sleep lol!

 

[mmaakk]

OK. My pair of 3870X2 is folding now with 4 Cores!!

AM I REALLY EXITED ABOUT THAT??

NOT YET...

Before the alterations the 2 cards were doing 2,300 PPD each.

Now with 4 cores I'm getting 1,300 PPD per core.

Resuming I went from 4,600 to 5,200 PPD.

I was expecting something better...

 

[mmaakk]

Hey Bow...

I noticed that it worked out!!

Cheers!

Are you sure you have all the flags set correctly? You should be getting better numbers than that.

 

[mmaakk]

I did the exact same way when I had 2 GPUs running @ the same PC.

-gpu 0
-gpu 1

and now 2 and 3.

Opening the display, right away I noticed...

from around 480 iter/sec to 260 now.

OK, during the weekend I will play around better.

Cheers

 

[xazraelx]

My PS3 is officially up and folding =)

The server should be done before this weekend, although it's PPD may be a bit on the side. (6000+ and onboard HD 3200).

I'm not seeing this 10% increase. It looks like it's downloaded the right core, because it says 1.15 in the log. Does it need to finish the current WU before you notice the difference?

Ah, nvm. Looking back through the logs i was already running on the new core And there i was hoping for 6k lol

Same thing happened to me

Are my numbers good for a single card?

Please post the card/clocks/ ppd that you have so we can have a point of reference.

Will do as soon as I get home from work

 

[infrared]

Yeah, 5385ppd out of an 8800GT is very good! That was the whole intention of my other thread, so you can make the comparison youself

Your 8800GT is almost performing the same as my 8800GTS (5529)

Bow, I bet you can get more out of that card. Un-link the core/shaders and go for the following:

Core - 725mhz
Shaders - 1750mhz(or more)
Memory - 875mhz

Try that and let me know.
