Anyone know why the GPU miner instantly closes saying it was not able to connect to the server?
I have tried many different pools and none of them works.
post the contents of your config (or .bat) file
Probably there is some simple mistake there.
I am using a bat file with no settings.
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
sgminer.exe --kernel darkcoin -o stratum+tcp://drkpool.com:3333 -u x.x -p x
drkpool.com fail today. Try another pool.
