nVidia 1060 GTX 3GB ETC mining issue - HiveOS

[34GL3s]

Hi,

I have an issue with mining ETC on some of my 1060 3GB rigs. 1 rig with the same cards is working but the other rig has stopped showing some "Can't find nonce with device. Not enough memory". The rig configuration including software versions (OS version, nvidia driver, t-rex driver,..) are totally the same. is anybody else experiencing similar issue as I am?

Here is miner output:

Probably Xorg is consuming more VRAM on your first card than on the rest. You can check that by running nvidia-smi when the GPUs are idle.

@trexminer could you please check output of nvidia-smi? It looks fine to me.

Yes, it looks fine. Perhaps there is enough space for DAG but not for CUDA kernels and GPU#0 was the first to hit this limit. I believe it's time to switch to another coin as DAG keeps growing.

[34GL3s]

Do you think changing GPU#0<->GPU#3 would make any difference?

[trexminer]

It shouldn't but I wouldn't bet my house on it :) Even if it did, it's only a matter of 1-2 weeks before you run out of VRAM because of DAG growth.

[34GL3s]

alright, thank you for your support :) will try to find another profitable coin.
