Title: Avalon 841 PG 3 Post by: ccgllc on May 03, 2018, 03:55:58 PM Most of my Avalon 841`s have a "15" under the PG column to the far right (hovering shows that as "Power Good"). One has a "3" and is underperforming.
Should I just swap the power supply? Update: I have spare PSUs, so went ahead and swapped it out. Problem appears to be solved. This is also the unit that was running about 4C higher in temp prior to the PG number changing. Of course, will continue to monitor it. Title: Re: Avalon 841 PG 3 Post by: philipma1957 on May 03, 2018, 04:14:26 PM Nice find This will be helpful to some of us.
Also a good feature put in by Avalon. I gave you a merit point for finding it and posting it. Title: Re: Avalon 841 PG 3 Post by: ccgllc on May 03, 2018, 04:19:24 PM Thanks... lets hope it holds as stable.
FWIW - That particular unit was using an Antminer APW3++ PSU. Title: Re: Avalon 841 PG 3 Post by: HagssFIN on May 03, 2018, 04:22:35 PM Yeah, the PG value is usually something like 15 if your PSUs are perfectly ok
and it can be very low if there are some psu issues. Title: Re: Avalon 841 PG 3 Post by: ccgllc on May 03, 2018, 06:23:13 PM 2 hours later it seems to be doing fine. Its one of my slower units at 13.2 with -1 voltage.

Its one of my slower units at 13.2 with -1 voltage. still above 13.0 spec --avalon8-voltage-level -1 are you doing this setting or --avalon8-voltage-level-offset -1 all of these below reduce hash a bit and temps and watts a lot --avalon8-voltage-level -1 --avalon8-voltage-level -2 --avalon8-voltage-level -3 --avalon8-voltage-level -4 they seem to work far better then --avalon8-voltage-level-offset -1 or -2 Title: Re: Avalon 841 PG 3 Post by: ccgllc on May 04, 2018, 02:56:19 PM Currently doing --avalon8-voltage-level-offset -1
Title: Re: Avalon 841 PG 3 Post by: philipma1957 on May 04, 2018, 03:04:04 PM Currently doing --avalon8-voltage-level-offset -1 this should be better --avalon8-voltage-level -1 especially so in hot rooms. Title: Re: Avalon 841 PG 3 Post by: ccgllc on May 04, 2018, 05:50:46 PM My results seem to differ from that. I'm running about 2C cooler and faster using -1 offset.
I'm running short test (like 10 minute ones) in order to minimize outside air temp changes impacting the results, but so far, its repeatable.

I have march 6? i think Title: Re: Avalon 841 PG 3 Post by: ccgllc on May 04, 2018, 09:39:05 PM which firmware?

I have march 6? i think mm: 8411803-14b0f10 May 4th firmware This is why I ordered a second setup. I want to be able to easily cross compare firmware. Based on your info the May 4th changed something. You get different results then the March 6th firmware. If I run on completely separate rasp pi’s I can sort out what the differences are.
