Windows BOINC reporting incorrect available memory for NVIDIA GPU

I recently did a clean install of Windows 7 x64 on my laptop. At that time I installed the latest NVIDIA drivers for my GPU, (driver version 306.23) as well as the latest stable version of BOINC (7.0.28_x64). I noticed the system wasn't responding like a fresh install should or has in the past. And today I had a BSOD which as far as I can remember has not happened before on this system.

Shutting BOINC down resulted in a long wait and required restart as the system became very slow to respond. With laptop restarted and BOINC shut down laptop responded normally. I later noticed BOINC has been running GPU apps for SETI. Seeing as my GPU only has 128MB of memory I knew it shouldn't be and as far as I can recall it never has before.

Prompted by the info and logs mentioned in the post:

I noticed mine were similar but I am using Windows 7 x64. Here are the relevant lines from my log:

9/23/2012 6:51:32 AM | | NVIDIA GPU 0: GeForce 8400M GS
(driver version 306.23, CUDA version 5.0, compute capability
1.1, 128MB, 8380482MB available, 38 GFLOPS peak)

Has this been fixed in the newest BETA

Thanks. I looked through the link you posted but I did not see anything resembling my issue.

Using the BOINC bug reporting site I noticed other posts in regard to NVIDIA memory reporting problems and they may have fixed the problem in 7.0.36. Before I saw that info, I did conduct my own testing using the current listed beta and it resulted in the same problem.

But for reference.. without changing my NVIDIA installed driver I tried several x86 and x64 versions of BOINC and I found that BOINC x64 versions higher than 7.0.25 are reporting available video memory incorrectly. BOINC x86 versions tested appear to be reporting available memory correctly.

Install File:
boinc_7.0.25_windows_x86_64.exe
boinc_7.0.28_windows_intelx86.exe
boinc_7.0.31_windows_intelx86.exe (Current BETA)

Log Results:
NVIDIA GPU 0: GeForce 8400M GS (driver version 306.23, CUDA version 5.0, compute capability 1.1, 128MB, 19MB available, 38 GFLOPS peak)
OpenCL: NVIDIA GPU 0: GeForce 8400M GS (driver version 306.23, device version OpenCL 1.0 CUDA, 128MB, 19MB available)


Install File:
boinc_7.0.26_windows_x86_64.exe
boinc_7.0.27_windows_x86_64.exe
boinc_7.0.28_windows_x86_64.exe
boinc_7.0.31_windows_x86_64.exe (Current BETA)

Log Results:
NVIDIA GPU 0: GeForce 8400M GS (driver version 306.23, CUDA version 5.0, compute capability 1.1, 128MB, 8380435MB available, 38 GFLOPS peak)
OpenCL: NVIDIA GPU 0: GeForce 8400M GS (driver version 306.23, device version OpenCL 1.0 CUDA, 128MB, 8380435MB available)

Hope this helps.

Thanks, I had forgotten to add that download link myself and to mention that I did try BOINC 7.0.36. It is now reporting the correct GPU memory available.
