OpenCL error -38 - cannot write buffer for DAG GPU0 WATCHDOG: GPU error, you need to restart miner!!! R9 380 1 card . Please help

IF IT IS A 2GB CARD, IT WON'T WORK--

The Ethereum DAG file is now too large for 2GB cards.  You will have to switch to an Ethereum clone-coin that is at a lower epoch if you wish to mine Dagger-Hashimoto algorithm.       --scryptr

If you are in the know about the problem it is better to be silent. I have two of the same cards and they run on air without any problems. You didn't even read my question! But if you still believe in the great DAG file - then it's your problem! Back to the question!

YOU CAN GET THAT ERROR ON A CARD WITH MORE THAN 2GB--

I read your question, and it did not have much supporting information.  If your card has a portion of its memory allocated, there is not enough memory left to load the DAG file, and a reboot may be required to release the allocated memory.  This can happen on a 3 or 4 GB card when the miner had to restart without a reboot.  If the memory is not released in the restart, the DAG won't load.

If the DAG is not your problem, I don't know what is.  Perhaps you should not ask if you don't want people (I am a person, and not your personal, unpaid servant) to attempt to be helpful.  Good luck in your mining efforts.       --scryptr
