Default mfaktc hanging ?!

hello,
i´ve two gt 640 installed, mfaktc x64 cuda: 4.2, win7 x64 and latest nvidia driver.
after a while (15-30 min) the applications works with no GPU-load but full CPU-load without any progress.
that happens on both cards ( together and in single runs ).
i kill the mfaktc per hand and restart it, but that should not the solution.

anybody has the same "problem" ?

thx

Norman

after some hours dev1 is stable (atm).
i changed the config to:
NumStreams=10
CPUStreams=5
maybe that was it ?

but with dev0 i´ve no luck. after some minutes autoexit or freeze.
is there an alpha/betaversion to test with keplersupport ?

in mfaktc device info i see:
number of multiprocessors 2 (unknown number of shader cores)
maybe the card is not fully supported yet?

It should work on Kepler just fine.

The two *Streams options shouldn't be higher than 3. What were they initially?

both are 3 but with the higher settings the application has a higher "lifetime" :/
i dont know what i should do..
there is no busy system, most idle atm and no OC cards.
just 2 ordinary zotac gt 640.

is it the fermi gt640 (gf116) or the kepler gt640 (gk107)? Do you have the right drivers for them? If it is the kepler, did you actually use cc 3.0?
