-rvram -1

Yes use -rvram -1 or NBminer maby it works better,i think maby Phoenixminer developer is dead !!! Shocked

This worked for me too. That DAG epoch change caused 3 rigs to crash this morning. 4GB cards are getting tight now...

-rvram -1 WORKS PERFECTLY FOR 4GB AMD CARDS!!!

That was literally the first thing I said...

Get ready to move on Linux slowly. Windows reserves 300 + MB of VRAM. The current DAG size is 3.57gb. The Phoenix miner free vram check was set to 384mb by def. When the dag + win reservation is taken away from 4gb vram, only 130MB of vram is left (that's why Phoenix made the problem). And with the command -rvram -1 you have time up to DAG 3.7gb or ~ 1.7.2020. After that, Linux....until 21.12.2020.

In the case of mixed rigs with 8gb and 4gb cards, what will be the behavior? I seemed to have understood that if there is at least an 8GB card the rig should continue to work correctly, is it correct?

I think the lead card (GPU0) is better with 8GB VRAM as it reserves more than the rest if you check GPU memory usage in MSI Afterburner, or you can try integrated graphics for the main display output but I had problems with not being able to control the GPU voltages after that - that was nearly 2 years ago that I last tried though.

It would be interesting to understand now if it is working because this would allow to keep the 4Gb cards having only 1 8Gb card

That is impossible. Only hardware intervention

GPU0 needs more reserved VRAM for Windows, so by placing an 8GB card there, you don't need to worry about this. It is not to say an 8GB card first and the rest 4GB cards will work past 23rd December 2020, it is to say it'll work until then and not stop early.

no. that's total crap. DAG must be loaded into the VRAM of the GPU completely, if it does not fit => it will not work.

This is where we are now:
(both have PCIe as main GPU, "Low res" has no display, "higher res" has HDMI dummy display )

Actually sometimes the GPU seems to use shared system memory and drop the hashrate down to 1.5-2MH/s - which is still basically useless as it's slow AF.
