Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[outbreak198x]

is it right that i can't mine anymore with 2x gtx960 2GB, or should it work with the virtual memory, because, i set it >16GB and also set enviroment variables, but getting DAG error...

2gb card is to small for mining

You can't mine ethereum anymore with 2GB cards, but you can mine fork like expanse (EXP) or ethereum classic (ETC)

I am mining Expanse with my 2GB GPUs.

[outbreak198x]

so i tried to change to ETC mining....

same errors...

You sure your virtual memory is set correctly ? can you screenshot your virtual memory interface ?
Also what cmdline you use to start claymore

[outbreak198x]

just a simple line:
EthDcrMiner64.exe -epool etc-eu1.nanopool.org:19999 -ewal walletID

virtual memory shows me 49152, because on C:\ i set 32GB on other drive 16GB, tried also with fixed 16GB C:\ only, 32GB C:\ only, and some other settings.

Hi

Mined etc and siacoin with 6 rx 470 4gb better that mined only etc???

[m1n1ngP4d4w4n]

try to add this to your cmdline

-mode 1 -allcoins etc

if you don't,  the miner try to mine ETH for the devfee, hence your error in DAG creation, if you force allcoin etc, only ETC dags will be created.

Can you please post your config. Thanks
I got this "cannot create DAG on GPU" on y 3GB 7970 cards.....

I've been mining Zcash for quite long and couple days ago decided to switch some of my miners back to eth.
4 of them has been mining eth before and 2 of them not, all my cards are RX480 8G. On all of them this happens after couple hours
One of the cards randomly decides to mine on 7Mhs..

Have you tried lowering your OC ?

Oh..
No I haven't and actually I can't, atm I have only remote access, but I don't think that that is the case, not sure

Well it's probably OC unstable after a while for this card, or bios strap same, not all cards are equal sometimes some does better, and some does worse, also check your PSU load.

After couple restarts and messing up with config I managed to stabilize the rigs that hasn't mined eth before and they are at 29Mhs(3xVGA rigs).
The old rigs which were mining eth for months before are still showing 7Mhs..

so i tried to change to ETC mining....

same errors...

You cannot mine ETC, dag size is the same.

Many people found problem when they switched back from ZEC to ETH, most of them solved that with DDU + new driver installation.

Great,
It means I've done nothing wrong...
I don't want to try these steps remotely so I'll ask some local team help.
Thanks!
