What could be the reason for this message?
"opencl error -4 cannot write buffer DAG" after that miner freezes and I have to restart the rig.
I have virtual memory set to 20+ gigs on 8 GPU rig
use virtual file 8gpu x gpu ram size, for example 8x 4 = 32gb if u have 4gb cards. if you have 8gb, then 64gb cards and u are safe for future dag size+ some miners are option to use double size.
I had around 32 gigs actually, and now increased it to 38gigs. I no longer get the error message, however the miner crashes after a minute of mining, and nothing is written in the log file. I am mining with the default clock values and 14.7 miner
