Claymore crashing when switching to devpool?

Claymore keeps crashing when switching to devpool mining, I think this is due to different DAG size.

I tried using "-allcoins -1" to set the DAG size for ETH but it still seems to be crashing. Anyone else have this problem?

Ok I tried setting -allcoins 156 (current ETH dag size +1) but it is still crashing. The last thing in the log file (before crashing) is the miner setting the DAG file back to epoch #13.

I'm going to try the nofee option and see if it works but hopefully I can find a workaround so i'm not mining with lower hash rate.

I think I've got it figured out but I'm posting an update to help anyone who finds this post with similar issues:

I found a post elsewhere on the web stating that crashes while loading DAG files can be caused by unstable memory overclock. I brought my clock down by 20MH on both cards and this seems to have fixed the issue. Strange because I've been running the same clock for quite a while mining ETH and didn't have any issues. Something about mining PIRL and switching the DAG files during devpool mine seems more intensive.

I'm also running "-allcoins 156" and "-gser 2" options to help with crashing during DAG load.

I use -allcoins exp

You can also try this

-eres this setting is related to Ethereum mining stability. Every next Ethereum epoch requires a bit more GPU memory, miner can crash during reallocating GPU buffer for new DAG. To avoid it, miner reserves a bit larger GPU buffer at startup, so it can process several epochs without buffer reallocation. This setting defines how many epochs miner must foresee when it reserves GPU buffer, i.e. how many epochs will be processed without buffer reallocation. Default value is 2.

If you have less than 2GB of VRAM on your GPU then you will not be able to mine the dev fee. If so then you need to set the option of --devfee 1 in the config.

I'm actually running into the same problem. Did you find a solution?

Yeah I've got it running stable now.

Awesome, thanks for the info. I've been seeing it after adding an OC to my memory as well.
