Claymore may be placing both ETH and ETC DAG to each of your Cards.
No that is not what the -allcoins 1 command does. What it means is that during every single dev mining session you will need to load new DAG to mine for Claymore and after the dev miner is done, it will reload the older DAGs to continue your regular mining.
Isn't that for:
-allcoins -1 not for
-allcoins 1? TIA
It didn't worked anyways, so the issue is somewhere else.
I think what the above poster should try is to increase the virtual memory, only issue I can think of that causes this since all his gpus are 8GB. Phoenix works but maybe it allocates a slightly different amount of virtual memory and hence might not run into this issue.
Regarding "allcoins" command, I used it many times in the past.
Basically the issue is that if you mine some new altcoin with a Epoch of 10 and later switch to an Epoch of 300 for ETH, it will sometimes crash when it tries to switch to Epoch 300, so thats why there is the -allcoins -1 which mines dev fee first so loads Epoch 300 and later Epoch 10, this resolves some crashes however the issue is the constant writing of the DAG on the GPUs every 15 minutes, eventually one or more GPUs will crash.
This is why the only way to mine alts with Claymore was with the -devfree 0 at a reduced speed. It mined slower and not optimized but at least it never crashed because it never switched to dev fee mode.
