I keep getting these errors when running the Claymore Ethereum mining app.

cannot allocate big buffer for DAG.

Your card is likely not to have enough memory for the DAG see this post.

And more explanation about DAG concerns.

  • So I would think that was true, but isn't the DAG only 1.3 GB right now? Every tutorial I've seen says that 2 GB is the minimum.

  • Ahhhh. Okay. I must have been reading old articles. I guess I'll have to wait for a new proof of work method?

  • You won't be able to mine on Ethereum but you can put your GPU on another blockchain like Zcash or Monero
