Hey guys,
Apologies since I'm late to the game here but hoping someone can help me out. I have a D3 (19.3G) that has been buggy to say the least over the last week.
Question here would be if anyone think the firmware here may help me and what setting may be recommended as a starting point.
Symptoms...
It started with lots of HW errors then turned into 3rd board not showing all the chips (55/60). Thousands of errors happening in a very short timeframe. Sometimes over night that board will go to X's. Reboot used to fix it but then started showing less chips.
What I tried
Latest firmware from Bitmain
Not powering the 3rd board. This worked fine for a few hours then sometime over night the 2nd board went to all X's. Reboot this morning and now the 2nd board is experiencing the same issues I had with the 3rd board showing 55/60 chips.
It ran fine for a couple of weeks but now I've got nothing but headache with it and at $6-$7/day profits I'm really frustrated having paid $1600 for it and made less than $150 so far.
This is the PSU I'm using since I bought this from a guy who claimed it was new off of craigslist. I had to buy my own PSU and this is what he suggested. I have been running the the 1200W on boards 2-3 and the 750W on board 1 and the control board. Both units run well under the max of 1950W between the 2. I power on the 1200W first then the 750W.

My concerns are raised because I don't know if it's something "I'm" doing to this or it's just the nature of the D3. Not to mention I have since ordered (from Bitmain) 3 new S9 ASICs. One for end of December and 2 for end of January. 6 month warranty and due to make a good amount but I'm concerned I'll have issues like with the D3. ebay is fetching a good price though so my plan was to unbox 1 S9, run it and if problems I could always dump the other 2 on ebay.
Many thanks to all for your efforts and I appreciate your time.
