I installed the NV GTX 560 Ti on my test-PC (win XP Pro SP2 32bit, Q9550).
Driver 266.66 (deinstalled , installed), test-pgm: memtestG80, 3DMark06, FurMark all OK. MilkiWay-WUs OK. All SETI-WUs get -9 result_overflow.

Edit : I found another user with the same (?) problem :
smithwr3 , computer-ID : 5292938, with NV GTX 480

Maybe you overclock the GPU - try to run it with less aggressive settings or return to standard speeds to test will the error disappear.

Use GPU-Z
http://www.techpowerup.com/gpuz/

to check the GPU load and temperatures (if GPU is too hot it can make errors).

Thank you for that advice ! The temp was OK, but the settings . . .
My card is a Gigabyte GTX 560 Ti overclocked by faktory.
Original : GPU-clock : 900; Memory : 1002 (2004); Shader : 1800.
New : 822 1002 1644.
Now Einstein and Seti are running fine - more than 1 task in parallel (GPU).
OC is good for gaming - but not for crunching !

I see this all the time. Few people seem to know that crunching is more intense than gaming. Gaming typically doesn't use all of the graphics card's abilities. Crunching uses nearly all of it, and this makes the chips more sensitive to overclocking.

VDDC is not steady to Clock 900MHz of GIGABYTE Geforce GTX 560 Ti card because it is low with 1.000V.
The seti@CUDA stability operation limit frequency of each voltage of GIGABYTE Geforce GTX 560 Ti card (GV-N560OC-1GI) was measured with MSI Afterburner.
Let's increase this list in the standard and increase VDDC to 1.025V(@900MHz).
Or,
The stability operation is done to 850.5MHz(@1.000V) GPU Core Clock if it lowers.

VDDC , GPU Core Clock (GPU-Z 0.5.3)
1.100V 1012.5MHz
1.087V 996.9MHz
1.075V 981.3MHz
1.062V 967.5MHz
1.050V 950.2MHz
1.037V 934.6MHz
1.025V 918.0MHz
1.012V 904.5MHz
1.000V 885.9MHz
0.987V 872.3MHz
0.975V 850.5MHz
0.962V 837.0MHz
0.950V 810.0MHz

Do not you read easily because it translated Japanese in the machine?
