-eres 0 Got it working again, though not sure how well or for how long.
-eres 1 worked for me, didn't try eres 0 yet but maybe not necessary
Documentation from page 1:
-eres this setting is related to Ethereum mining stability. Every next Ethereum epoch requires a bit more GPU memory, miner can crash during reallocating GPU buffer for new DAG.
To avoid it, miner reserves a bit larger GPU buffer at startup, so it can process several epochs without buffer reallocation.
This setting defines how many epochs miner must foresee when it reserves GPU buffer, i.e. how many epochs will be processed without buffer reallocation. Default value is 2.
As far as I could understand, we have only few days for migrating on alternate miner. Maybe week, but no more. Am I right?
