I'm trying to do some pool mining using AlethOne, but get the following error:

Allocating/mapping single buffer failed with: "clEnqueueWriteBuffer(-4). GPU can't allocate the DAG in a single chunk. Bailing."

I'm currently using these instructions, so I've entered

http://ethereumpool.co/?miner=20@0xe425AFC9cC425E88f911Ba9d4E77Eef763bCef22

in the Pool URL field.

Best guess would be that it's equivalent to the -G that I always have to remove in the consolue version of ethminer. Could anyone help ?

  • Seems there isn't enough GPU RAM to write the DAG. – Andreas Olofsson Mar 30 '16 at 0:30
  • Which GPU do you use? – Afr Mar 30 '16 at 7:25

You have to set some environment variables.

Linux:

export GPU_SINGLE_ALLOC_PERCENT=100
export GPU_MAX_ALLOC_PERCENT=100
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1

Windows:

setx GPU_SINGLE_ALLOC_PERCENT 100
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
  • input all variables and still does not work – user2942 Jun 19 '16 at 22:51
