still no fancontrol with rx cards under linux ?
Please all linux users with rx cards waiting for this .. sure more important than colors in linux Wink

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,

When you have time do you think it's possible to implement this?

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!

What voltage are you running your 290s at 1100?

1100 was just an example. I actually run Hawaii cards at 1055 with voltage as low as they'll go, generally 1.03-1.06v. (actual)

Do you dual mine or ETH solo? Because I think I ran mine at 0.95V once but it was slow (25MHs) solo only.

What is your power consumption?

at 25 mhs? I dont remember, it was less than 200 watts I think like 175watts each.

It was too slow and couldn't dual mine so I had to raise the voltage.
