Latest pre-release version
[x86/CUDA-2.2] v2.9105.512 (beta8) 2009-07-26

I'm using
dnetc v2.9105-512-GTL-09072609-*dev* for CUDA 2.2 on Win32 (WindowsNT 6.0).
nvcuda.dll Version: 8.15.11.9038
[Aug 08 01:05:27 UTC] *** This BETA release expires in 37.08:20:23.00. ***

Seems to be working fine at 158.56 Mkeys/s with a GTX 275

I'm seeing 148Mkeys on a 8800GTX @ 1729 shaders (was>350 before this ). Something is very wrong with your core/setup.

I think it's the CUDA drivers, because my GTS0 could get almost as much as that to.

What drivers? I'm on latest 190.38 / 2.3 CUDA SDK etc + Server 2008 R2 64bit.

Your 275 should be destroying them blocks even at our reduced rates now. Obviously the only other thing really is other apps swallowing your CPU or your GPU OR wrong core selected.

Oh crap, it was forced on core=7
RC5-72: using core #7 (CUDA 4-pipe 128-thd).

Let's see what happens with -1 next
RC5-72: using core #0 (CUDA 1-pipe 64-thd).

Smoking now, thanks for the tip!
