Our GPU2 Results! / HOW TO INSTALL

[Marvin_The_Martian]

Modded inf is only for the installer, and only because the drivers originally linked was for the 260 and 280 only. If you just download the official 177.35's you never have to worry about the inf, some people just had used it to install the first version.

OK, cool. I'm pretty happy with 4700+ ppd from a $77 investment

add that on to current 6000ppd.........

That is sounding better and better all the time actually. Was thinking I should drop one in my single core box fold6! Except, I don't think the PSU is up to the task *edit* just checked the PSU, it is a 450W that has 20A on the 12V rail. Is that enough to run an 8800 with a single core A64, 2 sticks DDR, and a hard drive?

[Marvin_The_Martian]

You're outrunning my more expensive ( I hate the local market here ) 9600gt, and you'll start noticing that the other 9600gt's will get a much tougher time in the future compared to the g92's and up.

Though I might run better if you look at watts used per point per day, idk really though but 8800gt has to pull allot more with twice the shader count.

Well done Barnacle...
I simply run the GPU along with the SMP version..I do NOT set any switches or assign affinity's. It all works well together.

i just set up gpu2 and it seems to go alot faster when fah viewer is minimized/off, is that normal?

Yes. The viewer takes a lot of resources.

[grimREEFER]

so, if you're running smp and gpu client on a quad core, what cap is optimal for the smp client?
75% (3 cores for smp)?

[Marvin_The_Martian]

No smp all out, with higher priority on the gpu client so it will take whatever it need. No need to worry about things other then that. If you limit yourself to 3 cores you will get less gpu2 points.

ps, reason I actually openend this thread is because I haven't seen any mention of the -forcegpu flag, and I think it should be in here ( though this isn't really a good setup thread ).

forcegpu tells the client to skip the internall gpu test, and for nvidia and ati there are specific core codes ( r600 and g80 for all current cards for both brands ), so if you know your card is folding capable but you get the message that your card is not supported then this could help getting it running

[Shadowtester]

With the Linux Wine gpu setup you have to use the -forcegpu flag from what I was reading but I did not think it was really necessary for the straight Windows gpu client.

Guys,

sorry, not much time atm. Thing is: I got a machine here that is running dual HD3870X2 in CF, and I need to really test it for stability for like a week or so. Now what would be better than the GPU client running on all 4 GPUs
Can anyone give me a quick rundown on how to set up the client? Running on Vista (not sure whether it's 32 or 64, gotta check later).

Thanks

[Naja002]

Here this should help:

GPU2 configuration guide

Its for Vista and XP, but is/seems a little mixed up. It would probably be easier if you just follow the guide and then we can help you through any specific issues.....

HTH

75% (3 cores for smp)?

Assuming you have a Quad Core...
If you have 2 GPU's then:
2 GPU's & 1 SMP yields most ppd

If you only have 1 GPU then...
1-2 SMP's & 1 GPU yield most ppd

Guys, it doesn't work
I followed the Stanford website's guide on how to set up the multi GPU client, made 4 shortcuts for the two HD3870X2's, started up the 1st one (- gpu 0 flag) and that one runs fine. FAHmon shows 2400PPD which is about ok for one HD3870 core I guess (Catalyst 8,8).
But when I try to start the modded shortcut for GPU 2 (- GPU 1 flag) it just says my GFX card doesn't support GPU folding and I should use the standard client (lol). The same holds true for GPUs 3 and 4

Running on WinXP 32bit, can't use the Vista install because it's the customer's
I have removed the CF bridge, disabled CF manually (CF even worked without bridge thanks to the Asus Maximus Extreme mobo and its ing Crosslinx chip) and clicked every "expand desktop on this screen" box I found (8 of them lol, some told me it couldn't do that because that one was reserved fro CF and physics).

Help?

Does it show something like this:

[Marvin_The_Martian]

if it does, use -forcegpu r600 as extra flag.

Sorry Naja just had to finish your sentence for you

[Naja002]

Sorry, but that wasn't the finish of my sentence. Right now, I'd just like to know if I'm on the same page......

[Marvin_The_Martian]

Lol ok but let's assume you are since well I think you are

[jcool]

Does it show something like this:

Ya, that's it, I think.. stupid ass program, can't they create a ing installer that maybe says "insert number of GPUs here" and does the rest for itself?


Will try that -r600 flag (even tho it's not an r600? lol) and report back

[Marvin_The_Martian]

I know it isn't, doesn't matter. For nvidia it's G80 even if you have a gtx280

[jcool]

Well, that didn't work. The error message is gone, but I get all kind of weird effects when starting GPUs 2-4. Some start then hang, some start and then exit straight away. Damn beta software...

[Marvin_The_Martian]

Ok that's not that good. Can you post the log files from those clients? Though I think it's known that second gpu's sometimes have to be started more then once to get it running, so that's not really uncommon.

The straight exits is something I think we can fix, it might have something to do with the desktop extending that you did idk but maybe the logfiles might help!

And btw, which version are you using?

[Naja002]

Well, that didn't work. The error message is gone, but I get all kind of weird effects when starting GPUs 2-4. Some start then hang, some start and then exit straight away. Damn beta software...

I've just been through this stuff and this is what I would do:

Go to Device Manager and verify that each gpu is recognized, working properly and no conflicts. On the drivers tab--update the driver on each card. I don't remember the exact steps, but do it manually and direct it to the driver that you are using.

Reboot

Uninstall the GPU2 client and reinstall it (reboot in between if ya want)

That should get rid of the popup about the driver. You'll probably have one or more other issues before all is said an done. Let us know and we'll go from there......

^^^If the above does not work--try removing the -gpu 0, -gpu 1, etc. flags for now.


Check out this thread when You get time:

Need Multi-GPU Help......56K!

Long, lotsa screenshots, but may help out......

EDIT: Marvin has a Good Point about Extending the desktop. Its is necessary in Vista, so You will need to do it. You will mostly likely need a VGA Dummy, so here ya go:

DVI to VGA Dummy.....56K!

Very easy to make and cost effective. You will need one for each gpu. Also checkout the Multi-GPU thread about extending the desktop.

[jcool]

The clients all start now, I can set them up, then they download the FAH 1.1 core and then they exit saying they encountered a grave error. This happens for GPUs 2-4 consistently. GPU 1 (aka 0) is crunching fine but only giving 2300ppd according to FAHmon.

All 4 cards are listed in the device manager, all have the current driver installed (well naturally) and I'm on Win XP so I don't need VGA dummies.

Sorry guys, that's it then, I don't have hours and days to try this, either it works or it doesn't. Clearly, it doesn't. Seriously they should make like a working installer for this stuff, as I did nothing wrong - double checked all the steps, it's a nogo

[Shadowtester]

You did extend your desktop onto the other cards right you have to do that for both Vista and WinXP just in Vista you have to trick it into thinking there is a monitor attached with the VGA dummy or it won't activate the card for use.
