Kawpow/Ethhash dags and 4GB cards #751

Open hbouma opened 9 months ago

hbouma commented 9 months ago

I realize mining RVN on 4GB cards isn't possible, but would it at least be possible to at least put in a check so that a 4GB card won't try and create/load the DAG? The reason I ask is that I have a rig with of 6 cards, 3 of which are 4GB doing kawpow multi-coin pools like NiceHash given how profitable the alt coins are right now. It works great right up until it wants to switch to RVN and it totally kills the rig. Now I could solve this by solo coin mining, but it doesn't seem unreasonable to have a simple check to add as this is not a unique problem. Like Ethhash mixed coin pools have the same issue. The cards that can't hold the dag could go idle until the next job comes in that does fit.

Thanks.

Same problem Rig works for NiceHash Kawpow mining. 4GB cards on HiveOS (linux). If NiceHash sends a job with a DAG of less than 4 GB, everything goes fine. If a job with a DAG is more than 4GB, the rig freeze when creating a DAG. Automatic reboot does not work because the rig does not respond to commands. You need to check if the DAG does not fit into memory - overload the miner

i had to quit mining because of this. i want to nicehahs kawpow but 4gigs try to mine instead just renegotating till it gets a 4gig dag. nicehash really needs a 4gig variant of kawpow and other algos
