Did you solve it? I have the same problem after adding 5th GPU to my rig. Rig with 4 cards runs well.

[maxcom99]

The only solution was to run one instance per card...

I get the same error on a mining rig with 5 GPUs (4x nvidia 1070 8GB + 1x nvidia 1060 6GB), running Ubuntu Linux 18.04 (nvidia driver 460.32.03, Cuda 11.2)

I get the same error with ethminer 0.18 and with nvidia drivers 450 and 455.

The strange thing is that ethminer runs OK at my desktop PC with just a single nvidia 1070Ti 8GB gpu.

With this issue I've been forced to move to t-rex miner, but I prefer ethminer.

Any ideas please?

UPDATE: SOLVED

I managed to solve this issue on Ubuntu 18.04. It is ram related.

By installing at least 8GB of RAM, ethminer can genetrate the DAG file and proceeds to mining. Bear in mind that just expanding swap file did not work - even with a swap memory of 8GB, ethermine did not generate DAG file.

So, from epoch 389 ethminer needs at least 8GB of physical memory (RAM) to generate the DAG and start mining.

@digibill i have 4 GB VGA and 16 GB RAM on Windows 10 and it does not work

[digibill]

@okarpov The DAG file in now 4.10GB and it should reside within GPU memory for mining. So, at current epoch I don't think you can mine ETH on 4 GB GPUs....

i see, thx

I got the same error on an 8gb gpu (Nvidia rtx 2080 super)

[Ferryistaken]

Uninstalled and reinstalled ethminer-bin. It now works
