Error downloading array energyBuffer: clEnqueueReadBuffer (-

Postby MeeLee » Wed May 15, 2019 7:45 pm

Fist time I see this kind of error.
Is it because of a too high overclock, or a power issue?

Code: Select all
16:16:39:WU00:FS01:0x21:ERROR:exception: Error downloading array energyBuffer: clEnqueueReadBuffer (-5)
16:16:39:WARNING:WU00:FS01:FahCore returned: BAD_WORK_UNIT (114 = 0x72)


Most of the time, I get this for a bad overclock:

Code: Select all
2:29:03:WU00:FS03:0x21:ERROR:114: Max Retries Reached
12:29:04:WARNING:WU00:FS03:FahCore returned: BAD_WORK_UNIT (114 = 0x72)

The error message means there was a GPU reset by error. Normally this is due to GPU overclock. ( I got this once when my power supply was weak but then also the display went off )

I think it happened because I accidentally hit the fan trying to connect a cable.
The thing would just continue working normally, save for the error above.
The overclocks were set very mild.

The firmware in GPUs is designed to detect errors and attempt to recover from them. That firmware isn't very smart and there is no OS running inside the GPU.

Microsoft (and others) have some kind of error recovery process which may be designed simply to reset the GPU and restart the video processes -- which is fine if you're using the GPU to display the desktop but inadequate for FAH. Nobody objects if their screen flickers briefly, but if it does it frequently, it's a sign of a more serious problem. FAH cannot handle some errors which are not a problem for a video application.
