AK V8 + CUDA MB team work mod

Vager:
Ok here's the reason why my GPU stops working.. I'm not sure why..

Here's what a normal completed task looks like when it's worked on by my GPU

setiathome_CUDA: Found 1 CUDA device(s):
   Device 1 : GeForce 8800 GTS
           totalGlobalMem = 335544320
           sharedMemPerBlock = 16384
           regsPerBlock = 8192
           warpSize = 32
           memPitch = 262144
           maxThreadsPerBlock = 512
           clockRate = 1350000
           totalConstMem = 65536
           major = 1
           minor = 0
           textureAlignment = 256
           deviceOverlap = 0
           multiProcessorCount = 12
setiathome_CUDA: No device specified, determined to use CUDA device 1: GeForce 8800 GTS
SETI@home using CUDA accelerated device GeForce 8800 GTS

Priority normalize modification by Raistmer

Priority of process adjusted successfully
Total GPU memory 335544320    free GPU memory 230916096

Now here's what happens after SETI is CPU-GPU team is running for maybe 12 to 24 hrs.

setiathome_CUDA: Found 1 CUDA device(s):
   Device 1 : Device Emulation (CPU)
           totalGlobalMem = -1
           sharedMemPerBlock = 16384
           regsPerBlock = 8192
           warpSize = 1
           memPitch = 262144
           maxThreadsPerBlock = 512
           clockRate = 1350000
           totalConstMem = 65536
           major = 9999
           minor = 9999
           textureAlignment = 256
           deviceOverlap = 0
           multiProcessorCount = 16
setiathome_CUDA: device 1 is emulation device and should not be used, supports 9999.9999
setiathome_CUDA: No SETI@home capabale CUDA GPU found...
SETI@home NOT using CUDA, falling back on host CPU processing

The totalGlobalMem is showing -1 and the Major Minor values are showing 9999, 9999 . I also notice that the MB_6.08_mod_CPU_team_CUDA.exe Process is pegged at 50% instead of the usual low value everytime the CPU feeds data to the GPU. Then What I do to simply fix this is just restart BOINC, after that everything seems to run fine once again.

Please keep in mind that I just today upgraded to a Quad Core Q6600, so I'm not sure if this will still happen. I was running previously a Dual Core E6600.

Thanks

i use Asus Striker 2 Extreme but my memory is weak it is only 1333mhz corsair  :-\ if i had a 1800 wow  :D

Program failed to find your GPU for some reason... try to chnage video-drivers or underclock GPU a little - maybe it will help...

Raistmer:
I lost main HDD drive on desktop PC tomorrow (it fails on self-boot test, some hardware failure) so will be busy with data restoration for some time...

k6xt:
I don't know if this is believable: My PC has run Raistmer's optimization for several days now. Some of the CUDA units are earning results. Comparing work units earning similar credit (i.e. say 50 points) a CPU will take 3500 seconds while the GPU takes 130 seconds.

This would mean my GPU 8500GT, one of the slowest  and oldest CUDA capable on Nvidias list, without any overclocking, processes about 7 times faster than all four overclocked Q6600 cores combined!

But, there are several (4 to 8 or more) CPU work unit results  between each GPU result in the PC task list. This fact would argue at best the GPU is only equal to one CPU. Or that the GPU is frequently idle. I don't quite know how to find out.

Maybe the times are not accurate.
