Ok. Without AERO CUDA is working.
setiathome_CUDA: CUDA Device 1 specified, checking...
Device 1: GeForce 8800 GTS is okay
SETI@home using CUDA accelerated device GeForce 8800 GTS
V12 modification by Raistmer
Priority of worker thread rised successfully
Priority of process adjusted successfully
Total GPU memory 335544320 free GPU memory 268029952
setiathome_enhanced 6.02 Visual Studio/Microsoft C++
Raistmer:
Well, I think it's possible to fine tune Aero by disabling some of effects and leaving most desirable ON if you like.
I found Aero in Win7 much more useful than in Vista. In Vista it's just waste of resources IMO.

Ok. Of course disabling totally AERO, the free mem is now 268029952 (was 209862656 with AERO on) and this value is very near to the minimum (256KB) amount of memory. So it's difficult to fine tune.... too much near to the edge, I think.

Josef W. Segur:
The best estimate of the actual required minimum free GPU memory is about 220 MiB, my guess is it's actually 128 MiB plus the 89 MiB the S@H CUDA code actually allocates. That would be 227540992 bytes when multiplied out.
Your "Total GPU memory 335544320 free GPU memory 268029952" says that Win7 is using 64 MiB even without Aero, which seems high to me but I'm a minimalist type :P I suppose it indicates you're running at 1600 x 1200 resolution or similar.

+it could be background, maybe some animated cursors and so on, windows had many candies even w/o Aero ;)
