Yes, i'm back on AK8, since there will be a stable one.

@Raistmer : Great Work!
But, how can I manage to run 4 + 1 with BOINC 6.4.5
I run Einstein and SETI Beta, but only 3 core's of my Q6600 running einstein and 1 core is almost idle, with the CUDA (8800GT) running.
Is it possible to run all 4 core's on einstein and the GPU on SETI Beta?
Anyway my system hangs from time to time for about 1 or 2 seconds. Should I increase the Memory-Bandwidth or try another CUDA-driver? When I stop the CUDA-App it all works fine without any hang up.

hi there yes my systemhangs too at exatly at the 15 second it is cuda problem or nvidia driver problem ...
The GPU need's cpu power so it can't do it for now
Best Regards

This modified app WORKED ON 8800GTS 320MB!!!!!!!!

Raistmer:
1) About 4+1 mode. Look at my original post in this thread (btr, any modifications will be posted there, so it's wise to check head post time to time):
"
7) For best CPU and GPU usage I recommend to set number of processors available for BOINC to real_number_of_cores+1. This will mitigate current BOINC bug with CPU+CUDA scheduling and will allow fully load CPU and GPU.
"
2) 15 seconds problem still unsolved AFAIK. CUDA itself is not very mature technology still. For example, no CUDA kernel can't run more than 3 seconds continuosly or CUDA will crash. Maybe it's the case here.
3) it's definitely not my merit - to allow 8800GTS to tun :) Maybe it's consequence of app_info.xml use.... Maybe it's worth to recommend using of my package for other 8800 owners too...
