I keep getting "not enough GPU memory to place DAG, you cannot mine this coin with this GPU". This started with epoch 351. I reinstalled Linux and it disappeared until epoch 352 today. I thought it might be a bad disk as it's not functioning so well but it's still the same on a new one.
I don't have this problem on windows 10. The whole reason I switched to Linux was it has less problems and is supposed to mine for longer. This can't be a memory problem as it's still mineable with over 250MB free. Also if the DAG size was the issue it would have stopped on card #1 ages ago as this has about 80MB less memory available but it's with all cards.
This miner is buggy and it's been like this even 2 years ago with 8GB cards. I see it's no longer being maintained as well and is 10 months old.
Yes. claymore should upgrade his miner to fix those 4GB problem.
But there are other miners on which 4GB cards are still working under SimpleMining OS.
Regarding windows, the main problem is that windows has graphical interface which allocates some memory in gpu.
Linux can be hadless and does not have this problem so putting 8GB makes sense only in windows.
Yet you can try in claymore using some options that load dag slower or uses different kernel.
