(forgive my english, I use a translator)
I've been following this topic for a long time, since I have 2 pieces of D3.
Yesterday I decided to try this firmware, and I would like to share the result and maybe get help.
I sat almost all day to set up one of my D3 on this firmware. I wanted to get the best performance, since noise for me is not important.
(on all my devices fans are set to 85% in manual mode)
Factory firmware on two D3 is set to 475Mgts - while it consumes 1050W and produces an average of 17 GH/S, and the total number of errors from all boards = about 20-40 per day.
At first I tried the beta firmware.
I tried to configure everything manually, without the use of automatic settings. Within 5 hours I was not able to achieve the work of D3 without a lot of errors, even at a speed of 18.5 GH/S.
Because of the constant reset of the number of errors, it is difficult to understand how stable the device works.
View error statistics, you can use the Awesome Miner.
With the firmware version 1.12, everything turned out better, but the final result is not very happy.
After a long search of the frequency and voltage settings for each card separately, the best I've got are:
1 boards - 487 MHz - voltage 14 (this is the worst of the boards for quality)
2 boards - 531Mhz - voltage 15
3 boards - 531MHz - voltage 13 (this is the best board for quality)
At the same time, the production rate was about 19.2 GH/S
But the number of errors is about 2 per minute or even more.
I want to ask the developer why it happens, if you restart the mining (or reboot completely), without changing the settings, just click "save&apply"(or reboot), every time after this, the number of errors is DIFFERENT!
I tried so several times, and the number of errors was from 1 per minute to 10-15 per minute! With absolutely unchanged settings!
Can someone tell me what my mistake is?
Why can not I configure the higher performance on this firmware?
Or this firmware will not help me achieve better performance without errors - compared with the firmware?
Will it only reduce the consumption of power and noise at the same performance?
Here is the result of which I achieved:
