I saw that the half speed BUG on GTX560TI (440mhz instead of 880mhz) in case of manual overclock (factory default speed is 880mhz) is not really corrected with use of the oldest NVIDIA compatible driver 266.66
And previous driver 266.58 is not working on GTX560 but is ok on GTX460

Since I realize that, i dont overclock at all my GTX560TI and reboot the PC to restore a real 880mhz speed
my GTX560TI is a twin froz II modele from MSI capable to run at 1,1Ghz !!

I hope that some one will fix that bug so i will be able to use the full power of that recent GPU with a good overclock for crunching !!

I own 3 GTX460 and one GTX560TI

on GTX460 I saw no probleme using NVIDIA driver 266.58 and Lunatics_Win32v0.37_AP505r409_AKv8b_Cudax32f

BUG: on GTX560TI with NVIDIA driver 275.33 and lunatics_Win32v0.37_AP505r409_AKv8b_Cudax32f, the GPU was only 40 degré while crunching WU and GPU-Z_ASUS_ROG_0.5.3 report a frequency of 440mhz instead of 880mhz ! even on my old 9800GT crunching results were better than on my new FERMI GTX560TI card. Maybe this BUG is related to the new CUDA compute capabilities in the NIDIA serie of driver 27xxx !

SOLUTION: I install the oldest NVIDIA driver 266.66 compatible with my GTX560TI and it's work fine full speed all time now !

thank for the answer but i solve my problem with GTX560TI doing this:

1) restoring my windows system partition using clonezilla USB version
2) uninstalling boinc
3) removing all my boinc files
4) reinstalling boinc official version wu ok
5) reinstalling lunatics fermi application (Lunatics_Win32v0.37_AP505r409_AKv8b_Cudax32f.exe)

wu calculations complet well now even by using resheduler for VHAR VLAR wu (boinc_rescheduler_2_5.zip)

have a nice day

i also buy a GTX560TI and replace a GTX285
i checked the GTX560TI with somes games and a stability utily: VideoCardStabilityTestSetup.exe hardware is OK

after reinstall boinc

and i get also all my SETI@home WU finish in a couple of seconds without error
in 1 hour time the GTX560TI finished calculating more than 1000 WU !!

what the trouble ?
i run 2 GPU instances and re install BOINC with official binary:
setigraphics_6.03_windows_intelx86.exe
cudart32_30_14.dll
setiathome_6.03_windows_intelx86.exe
libfftw3f-3-1-1a_upx.dll
setiathome_6.10_windows_intelx86__cuda_fermi.exe
cufft32_30_14.dll

same result 1000wu in one hour on GTX560TI

i replace GTX560TI with the GTX285 everything is normal again (1 Wu in 20mn)
even with optimized binaries:
MB_6.08_CUDA_V12_VLARKill_FPLim2048.exe
AK_v8b_win_SSSE3x.exe
libfftw3f-3-1-1a_upx.dll
cufft.dll
AKv8SSSE3x.aistub

how can i solve this ?
