Jet, getting multiple GPUs to work can generally be tricky and is unrelated to the current problems. Sorry, can't give you more help on that right now. The other problem you're seeing, i.e. the strange behaviour of 6.6.36.. is by design. It's asking all projects for CPU and CUDA work (the Devs figured this wouldn't matter) and it can be quite picky about which tasks it actually starts. If you want to give it another try you should reset your debts upon installation of the 6.6.x version (otherwise it might screw things up.. do you know how to do this?) and if BOINC still refuses to start the GPU-Grid WUs you can suspend all other projects. Then hopefully BOINC will decide to keep your GPUs busy.

Scanning for our furry friends since Jan 2002

ETA, thanks for advices. You are totally right, running multiple GPU's is a real challenge, in my case it just make it even more interesting.
Anyhow, I would continue attempts to push all GPU's running together for GPUGRID.
Basic action plan (:-) is exactly, as you described, to start it again, practically from scratch, consequentially, clean install etc.
Thanks for the ideas,

Regards,

Jet

FYI Driver 190.62 released on Aug 21.

But does it work?

With a GTX260 and GPUgrid?

testing it as we speak, and which crackhead had them change the number of task in queue????? i liked it at 2.

We have now selectively assigning a cuda2.3 application to people with a 190 driver only. This is a test. We keep it on if it does not give problems.
It should be transparent to older driver users.

You need a recent BOINC version to receive the new application.
Only for Windows so far.

Where do you get the 190 drivers? I just upgraded to BOINC 6.6.36 as requested, so where do I find the new driver?

Windows Vista 64 SP2 with a 9800 GT

Just to make life interesting I updated the drivers to 190.62 yesterday and BOINC 6.10.0 the day before (can't get more recent that that).

BOINC seems to be working fine and the 190.62 drivers seem okay with Seti and cuda 2.3, so figured its time to re-test GPUgrid with the new driver. The machine has dual GTX260's. It just downloaded the cuda 2.3 app and 5 wu. I will report back once they are done.

Well 3 failed, 1 worked and 1 more is still running (currently on 80%). Links to failed wu:

So, there is short story:
1. Using Zydor's advice, all nVidia drivers was uninstalled ( with Driver Sweeper).
2. Old version BOINC (6.5.0) was replaced by new one 6.10.0.
3. New driver (198.38 CUDA 2,3) was installed, according to the Zydor's methologie (under safe mode). Due to the fact, that nVidia's web site is down over 12 hours, was unable to get more recent driver version (198.62, for example.
4. A cc_config.xtml was added to use all gpu's.
5. First attempt with total new software brings practically zero result, I was unable to use 3 GPU's, BOIC was showing just two of them. Device manager, nVtune & GPU-Z still shows 3 GPU's. Kind'a tricky, yeh.
6. Decided to make some relocation of GPU's on the MoBo (ASUS WS Evolution, having 4 PCI-E slots). After movement of GTX 260 to another slot (closer to other GTX), strated BOINC again & suddenly found, that all GTX 260 is in the system & recognized by BOINC. Very happy. That means, that PCI-E IRQ (or else) distribution managed by MoBo is quite important for systems with multiple GPU's.
7.So, get a couple of WU's, crunching with new system less than a day. Almostcompleted 6 WU's up to now, looks, that most running fine.
Having a very strong feeling, that new system ( driver, BOIC & 3 x GTX 260) is a little slower at the moment. New drivers ? More "heavy" contemporary WU's ? I don't know exctly.

So, the first battle result is acceptable. Let's look into the future.

Thanks for the advices & support. Special thanks to Zydor!

Last one failed too. It can be found here

I did uninstall drivers before upgrade. However driver sweeper failed (gave a memory address error) when I tried it (a couple of times).

After driver install both GTX260 are seen by BOINC without the need for a cc_config as they are identical cards.

Hi,

where did you find boinc 6.10.0? The highest version, that is offered, is 6.6.36 at http://boinc.berkeley.edu

I've also tried to install drivers 190.62, but WU's fail after 10 to 15%.

Vista64, E8400, 6GB, GTX260 and a lot of troubles.

Regards,

Alexander

Have a look in http://boinc.berkeley.edu/dl/ for Boinc manager 6.10.

Another two broken Wus...

From Siberia with love!

Sorry I'm reverting to the 18x drivers as I'm having too many problems with the 190.x dropping into power save mode and staying there, getting such poor performance is killling any gameplay.

Important. Anyone is welcome to revert to older drivers. We are just trying to give you the possibility to use the new drivers if it's good for gaming for instance.

gdf

The problem is under 18x drivers I get no WUs with the error about needing 190.38 or better for CUDA 2.3

You need at least 185, the error message is misleading.
