Multi-GPU client help for everyone

[[XC] Synthetickiller]

There are people out there running these monsters, 2,3, and even 4 card behemoths out there destorying all that stand in their path.

We need walkthroughs on the site not only for vista, but for our xp users as well.

I myself have failed miserably trying to get a multiple gpu client working, so I am not the guy to ask.

Instead, I ask anyone out there to please post a walkthrough for either or both that they KNOW works.

I'm running 2 clients on XP.

I followed this guide...

Thank you!!!!

One down, one to go.

Vista anyone?

[The_Barnacle]

The guide I linked to has instructions and screenshots for both Vista and XP.

Ok I'm not all that great at this but here is exactly how I got 2 GPU clients to run on my 9800GX2 in Vista x64.

Step 1: Download version 6.20 from http://folding.stanford.edu/English/DownloadWinOther
Step 2: Create 2 folders on desktop
Step 3: Copy downloaded file to both folders
Step 4: Run as -configonly, just set it up like any other console client but when it asks for Additional client parameters put -gpu 0 for the first client and -gpu 1 for the second one.
Step 5: I go into each folder and click on the F@H icon and they both open up fine. I have been using this same configuration for the last 2 weeks and have not had a single issue.

here is a picture of 1 of my clients

For XP this is what I did.
You will need Riva tuner and the gpu console.
I used 177.79 drivers.
Install driver reboot. Install riva tuner. Extend desktop to other 2 gpu. Use RT to enable ocing on all cards. Reboot required on other 2 cards. Made 3 folders in root of C: called GPU1 GPU2 GPU3. Copied console installer to all three folders and installed. Configured like a SMP. Set machine ID’s to match folders 1,2&3 When asked to set Additional client parameters I set them as –gpu 0, -gpu 1, -gpu 2
There are probably a few reboots I missed but I’m sure you will find them

Thank you guys. This clears a lot of stuff up for a lot of people.

I hadn't tried dual gpu clients since 6.22 came out. Must be 10x easier and seems like it. I do miss my molecules floating around though. :p

[ThunderDuck]

All the guides I'd been reading just seemed like they were making it harder than it needed to be.
When Atlas posted that he set it up just like a SMP it got me thinking. So I tried it and it worked.

[[XC] Synthetickiller]

Sounds good. I was trying to get the previous version of the vista gpu client to work and nothing came of that.

Now I just have to cross my fingers that it will work in the future the same way and not regress back to something more complicated.

so does gpu console run any better than the display client in terms of more ppd? i like the console because it isnt something that can be easily closed out of when my friends or family use my computer

[Marvin_The_Martian]

No point diffrence at all, the core client functionality is the same it only differs in the system tray icon code and handling vs the dosbox you get floating on your screen.

In previous clients the console clients where the only one's which you could run multiple instances of.

Edit: If you think our guides are not fully coverd, and you found a guide somewhere else, you are free to base your own guide for XS on that one if you give the proper recognition ( maybe ask prior permission even? )

I agree it looks better if you can link to your 'own' team forum for guides and don't have to link out. Though I don't mind it either, and it's also rewarding for those persons/teams who are first to put up good/great guides?

What do you all think about this?

Do you change the cpu affinity at all ? I assume it's on the QC
I found that it always defaults to cpu 1 even with the "no cpu lock" option,mind you that's on a DC
So I ended up running 2 instances of "getset" (thanks MikeB12) to split the load.
Which board is that with 3 gpu slots ? Lanparty?

I run both the console and the Systray,wanted to see which one is "better" can't see much difference...

[Marvin_The_Martian]

SocketMan I'm taking you mean SetAffinity when you say 'getset'? And no, there is no diffrence in points in this version between the two variants ( as long as you don't use the viewer ).

[ThunderDuck]

When I disabled the affinity lock all three gpu's would be set to core 3. When I left it enabled they set to cores 1,2&3.

As for the board its a 780i that I took out of my game rig.

[Marvin_The_Martian]

Thanks for that info ThunderDuck

Yea that's the one.
I run 2 instances (rename the .exe to allow that) and add "fahcore11.exe"
as a favorite.Seems to work pretty good on my nf4 Expert.
I just took it back down from 3.00ghz to 2.00ghz and there is no
difference in ppd.
Huge difference in the heat output (the lack of it) and much lower
Vcore
Wish ATI was similar
thx T.D.

[Marvin_The_Martian]

2 instances of setaffinity? Why? And dropping a gigahertz is something which should definetly show up in your production unless something was still of to begin with. Why don't you post some screens with fahmon showing, log files, cpu-z and gpu-z, the whole shabam you know what we need..

[angra]

I have brought up a spare old machine in my office with the intent of using my idle 9600gts in it.

I think that I have updated everything properly, but the console and systray clients both refuse to start with -gpu 1. The error report is:

At present your GPU is not supported or you need a current driver.
...

Both cards have up to date driver. Any gotchas that I am overlooking here? Thoughts?

Added this thread to Master Sticky...

[[XC] Synthetickiller]

Thanks! My wish has come true! I get a sticky w/o actually doing anything!!!!!!!

[angra]

OK so what's the answer? I am using xp32. Any thoughts?

[ThunderDuck]

Did you extend the desktop to the second gpu? And the flags should be -gpu 0 and -gpu 1

[angra]

Aha! Extend the desktop was it.

using correct flags already.

Thanks! that's 3.5k more ppd for the team

I followed Burson's Guide up top and I keep getting UNSTABLE MACHINE Error on GPU_1. However GPU_0 Is working just fine. I have SLI Disabled. whats the deal?

You're folding on a GTX295?
