Message 1149136 - Posted: 5 Sep 2011, 11:00:21 UTC

Hello to all..
Today I install one more GTX 295 to my rig with id 5867601.
At the very beginning the card is sending computation errors, so i removed it from the system for now.
Any ideas why is that?
All gpus are stock timings, EVGA, no dust in it.

With (at that time) five CUDA compute resources in a single host, you probably ran out of a key resource - I'm guessing kernel mode CPU memory, from what I've read from the developers. The errors start with

Cuda error 'cudaMemcpy(&flags, dev_find_pulse_flag, sizeof(*dev_find_pulse_flag), cudaMemcpyDeviceToHost)' in file 'c:/[Projects]/X_CudaMB/client/cuda/cudaAcc_pulsefind.cu' in line 1614 : unspecified launch failure.
Cuda error 'cudaMemcpy(PulseResults, dev_PulseResults, 4 * (cudaAcc_NumDataPoints / AdvanceBy + 1) * sizeof(*dev_PulseResults), cudaMemcpyDeviceToHost)' in file 'c:/[Projects]/X_CudaMB/client/cuda/cudaAcc_pulsefind.cu' in line 1626 : unspecified launch failure.

on the sample I checked.

This is a highly technical area - I suggest you PM jason_gee, who wrote the app you're using.

I am using 2 285's and 1 295. I removed the spare 295 as fault.

BOINC don't report the grafic cards correct (or it's wrong displayed in the online overview (server software)).

Tim have as GPU#0 and #1 a GTX285 each.
GPU#2 and #3 is a GTX295.

It's displayed [4] GTX285.
But this mean, this is the first grafic card (GPU#0) and all other counted/added GPU chips.

It's a pity that the grafic cards are not shown as:
[2] GTX285
[1] GTX295
(IMHO, this would be the best)

or chips:
[2] GTX285
[2] GTX295


Maybe someone could/should contact the DEVs (or admins)..

If you look at the stderr.txt output from one of Tim's GPU results you see:
