hi there,

i need some help/explanation: i recently discovered that the gpu-WUs for my nvidia 220 GT take a lot longer then normal. They also use 100% CPU according to the task-manager and not the indicated 0.14 % CPU.

anyone got a solution to this problem? thanks in advance. me specs are:
WIN7 64bit, always newest drivers for hardware, newest boinc client etc.

Seti cannot use your GPU. Here's the relevant lines from a completed WU's log:

"setiathome_CUDA: device 1 is emulation device and should not be used, supports 9999.9999
setiathome_CUDA: CUDA Device 1 specified, checking...
Device cannot be used
SETI@home NOT using CUDA, falling back on host CPU processing"

Since Seti can't use the GPU, it "falls back" and runs the unit on a CPU core.

Someone with some program/error message knowledge could probably offer you a more detailed explanation of the error.

thanks for the answer, that's an explanation. but since it worked before i want an answer if something changed from the seti-side. otherwise i will probably fall back to older drivers.

---

Without digging too deep, this is probably the same problem others have reported regarding the 295 drivers. Did you recently upgrade drivers?

See this thread for the reason why:

Error while computing

thanks everyone. YES, i recently updated drivers and in retrospect it was probably the time when the problem occured. i try the workaround from the other thread and -if not working- downgrade the drivers.
