I have an issue with one of my three crunchers http://setiathome.berkeley.edu/show_host_detail.php?hostid=6633956 .

It is quite happy running CUDA tasks on nVidia driver v301.42 as per this extract from the log file.

I have now reverted back to v301.42 and all is well.

Any help would be appreciated.

---

Have you tried any of the beta versions? The current one is 7.0.44 along with the current version of nVidia.

---

I don't buy computers, I build them!!

Many thanks for your reply.

I installed the latest BOINC beta v7.0.44, together with nVidia drivers v310.90 and still get exactly the same problem "missing coprocessor" for the 4 Geforce 8400GS's.

Reverting back to nVidia drivers v301.42 corrects the problem.

Any other ideas?

---

Try putting this line in cc_config file

<use_all_gpus>1</use_all_gpus>

Andy

---

That only helps for when the GPUs are actually detected but not used, not when they're not detected. BOINC can't go use all of something it hasn't detected.

---

Maybe a clean installation of Nvidia driver? :-(

Tim

---

It seems those Geforce 8400GS's aren't the newest models. Perhaps they are no longer supported by the newest drivers (just guessing;-).

They are according to the Nvidia website.

---

Many thanks for your replies & comments.

I've tried clean installs of the new nVidia drivers with no success.

As Bernie states the 8400GS is listed as a supported product under the v310.90 WHQL documentation.

Any others suggestions would be appreciated.

---

Did you try the new driver with less than 4 cards at once?

Gundolf

What was the filename of the latest Installer that didn't work?

Claggy

Claggy

The filename is "310.90-desktop-win8-win7-winvista-32bit-international-whql.exe", the one that works is "301.42-desktop-win7-winvista-32bit-international-whql.exe".

Does GPUCapsViewer detect the 8400 GS's as Cuda and OpenCL devices?

I have a PCI 8400 GS, it normally sits in my XP3200+ Win XP host, but i can put it in my other hosts, install later drivers and see if it is detected.

It is also time i did some benches on it of the latest x41zc apps, and see if the legacy GPU slowdown with 306.xx and later drivers effects it too,

Claggy

That's a pretty old CPU. Maybe nVidia did something to the Cuda 5 drivers that breaks BOINC with PIIIs. I looked, but didn't see any CPU requirements for Cuda 5. Just a thought.

TBar, that may well be the answer, the drivers after v301.42 include CUDA 5, so it may well be an incompatibility with the processors Intel(R) Pentium(R) III CPU - S 1400MHz [Family 6 Model 11 Stepping 4] (2 processors) and CUDA 5, although as you say there is no mention of CPU requirements.

Claggy, I've not been able to run GPUCapsViewer as it crashes out each time I attempt to run it. However I've run GPU-Z against the v301.42 drivers and it reports CUDA & OpenCL as available. I've lost the connection to the computer (VNC) before trying it with v310.90, and won't be able to restore the connection until Friday when I can get to the computer in person!!

Many thanks for your help so far.

I have had similar issues when I tried upgrading the boinc version on my rig from 6.10.60 to 7.0.28. I have been running nVidia driver 306.81 for a while now. Plus the issue is certainly not due to the processor as I have the newer AMD Phenom II X6 1055T. I have now reverted to 6.10.60 and all is well.

I have an issue with one of my three crunchers http://setiathome.berkeley.edu/show_host_detail.php?hostid=6633956 .

You might want to Stick to 301.42, my testing of 306.xx and later drivers on my 9800GTX+ showed a slowdown on the different x41zc Cuda apps, with the exception of the Cuda23 and Cuda22 apps,
In the meantime i've got my XP3200+/AGP4650/PCI8400GS running, and done some MB v6 benches, as you can see the Cuda23 x41zc app is fastest on most of the Wu's, so no need to upgrade drivers further:
(Note: the x41zc_Cuda22 times are misleading because it was run with Cuda23 dll's, normally it would be a lot slower.)
