Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)
Hello Everyone 
first post!!
i am running 2 rigs, all cards are RX 580 8g armors, Windows 10 with claymore v15, both rigs stopped working when the ETC epoch hit #379
All GPU's "not enough GPU memory to place DAG, you cannot mine this coin with this GPU"
"OpenCL error -61 - cannot allocate big buffer for DAG"
"OpenCl error -38 - cannot write buffer for DAG"
server: accept failed with error: 10004
my virtual mem is at 55000
AMD Drivers 19.9.2
im using AMD software for tuning GPU's "GPU 1165MHz, 853mV" "Memory 2080MHz, 853mV"
Now when i update drivers to either latest 20.9.2 or drivers back to near beginning of the year i can mine again but now the hashrate is 19.2
Without tuning gpus i get 22.4 hash
Before #379 my hashrate was 31.3
In my bat file i have "-eres 0 -epsw x -mode 1 -r 1 -strap 1 -rxboost 1"
looking forward to solution
thanks

It looks like your problem (and everyone's mining ETC) is that Claymore will only mine until epoch #384 for any Etash algorithm (ETH, ETC, Expanse, Pirl, etc), and ETC has almost reached that point (epoch #383). You can check the DAG file and the epoch on this site: https://investoon.com/tools/dag_size. ETH is near to reach an end too for Claymore mining and for 4GB cards on December 24th. You could start mining other coin like Ravencoin and stay tuned 'cause I read ETC is about to downsize the DAG file to increase the network hashrate by allowing 3GB and 4Gb cards to mine again. I guess It will attract old asics too. Hope this information helps you in some way.
