I have just started up an older machine in advance of the WOW event.

7181449

It has been running OK for 20 or so hours. Then I got 3 tasks all failed with this.


Error: Getting Platforms. (clGetPlatformsIDs)
BOINC assigns device 0
WARNING: BOINC failed to provide OpenCL device, using own enumeration abilities
ERROR: OpenCL kernel/call 'clGetDeviceIDs (second call)' call failed (-32) in file ..\..\..\src\GPU_lock.cpp near line 1128.
Waiting 30 sec before restart...
Priority of worker thread raised successfully
Priority of process adjusted successfully, below normal priority class used

About 100 times then task fails with too may restarts.

Any advice as to the cause.

I have restarted the machine and it is crunching OK at the moment.

Check for driver crashes in the event log.

The stderr output looks a bit familiar With what i have seen when the drivers for the gpu crashed.

Sorry, yes there was one solitary driver crash and recovery in the event log.

Usually I would expect to see more if it went on 100 times for 3 WU's

However you are probably right, I forgot this is Vista!!

Win 10 seems to be more forgiving, any number of driver crashes on Win 10 does not usually result in errors.

Advice on best driver for this setup?

Advice on best driver for this setup?

I gave up on trying to run any driver that supported OpenCL 1.2 on my Vista machine with a GTX 750Ti as it wasn't possible to get it to run without driver restarts occurring.
I suspected it might have been a combination of the 32Bit OS & 2GB video card causing significantly reduced system resources as a result of the very small amount of RAM left available to the system.

Not looking very good here.

Perhaps a better graphics card would be needed for this to work.

Not a very nice thing to say, but could be true.

GT 640 is quite good enough for me, and it should be good enough for SETI@Home.

Ah, Bernie.

This is a problem with the card, not a driver error as such.

Or oh, perhaps.

Ever heard about the National Science Foundation (NSF).

Guess they love to know about this error.

Bernie, personally I'd downgrade the video driver to 1 that doesn't support those SOG or OpenCL MB apps (I'm still using driver 314.07 on all mine), that will still let you run the AP as well as CUDA apps on that card and should eliminate your current problems.

Cheers.
