Be patient please. Now I'm working on updating Monero miner as promised (check its thread for details), it will take a couple of days. Then I will work on this task, as promised.

Hi Claymore,

I have an issue with DAG generation with some Hawaii cards that are extremely undervolted. The cards will mine perfectly without ever crashing, but at that low voltage they can't generate the initial DAG or the following DAG when it comes time to switch. They'll just crash while other cards in the system keep mining.

This can be solved by raising the voltage, obviously, but that means an extra 30-40w of power consumed on most of these cards which I'd like to avoid. Seems to me that there would possibly be two ways to fix this, while keeping the undervolts where they are.

1) Reduce the intensity of DAG generation? (Not sure this is possible...)

2) Add an option to the config file to lower GPU's core clock while generating the DAG? IE When mining use regular stable mining clock speed of 1100MHz, next DAG generation comes along drop to 900MHz while generating, when completed increase back to 1100MHz. Flags would be -cclock 1100 and -cclockdag 900.

Any thoughts? Hope this makes sense!

Thanks!
