I have using a graphic card of AMD R9 280.
how to fix the failed like "Allocating buffers failed with: clCreateBuffer (-61)"?
Please give me a solution.BTC
lol.
Your graphics card has 3GB of RAM. If you try to mine Ethereum on it, then you will fail. The dag file of the Ethereum coin already exceeds 4 GB.
You can try to mine Ethereum classic, but considering the power consumption of your video card and its hashrate, mining on it will bring you very little profit.
I sold these cards after Ethereum's dag file exceeded 3GB.
