Could you post the changelog to the L3+ firmware update 3.9? Thank you!

Thank you for updating L3+ Awesome miner firmware to 3.8.8, the fan fix was very important.
Is there a firmware 3.8.8 changelog? I don't see it anywhere.

I have a handful of antminers running in my setup, and they all work great, except this one that will drop from full speed to 5 GH/s(RT) every few seconds, in reported speed only. The average speed, pool shares generated, accepted shares per hr, HW, temps, net profit that actually shows up in the pool, and everything else I can check are all completely normal...this appears to be purely a display error on the miner status page. But if I plan on selling this in the future, obviously something I want to fix (also I get erroneous warnings in my awesome miner rules). The only anomaly I've found is on the Miner Configuration, Chip Freq settings page [both blissz or awesome miner custom firmware], one chip is showing 999.00, while the others all show around 1.9, which is something I have never seen on any other miner. Maybe that causes some sort of overflow error? I've tried adjusting that one chip all the way up or down and everything in between (and adjusting the overall miners global freq and voltages to every possible combination), but nothing changes it. Swapped power supplies, IO boards, reset to factory firmware to no avail as well.

Got one, but I'm a fixer, more interested in what went wrong and how to fix it. I found an S9 guide that used Putty and a serial connector to force a new flash of the ROM, but I can't find anything for L3+ boards (no explicit TX/RX pins). Anyone know how.

When I power my miner on, I can't open the web interface, nothing shows up on IP scan, ethernet lights up but no other lights (red/green) flash. Fans stay on super low and never spin up. Does not respond to holding reset or IP button factory reset methods (tried all 3 reset methods). Tried different PSU. Tried loading new firmware on an SD card, but when I insert the SD card and power up the board, I do not get the simultaneous red/green lights coming on as you are supposed to when it signals its loading new SD firmware. Nothing happens except flashing ethernet lights and the solid red 5v/3v power LEDs.
I've narrowed it down to the BB board itself (the smaller removable board with ethernet port), because if I pull it off the pins and swap in a different miner's "BB Black v 1.8" board, it works just fine. I did some probing with a voltmeter and every point that a working board has voltage, the non-working board also shows voltage. The TI A8 Processor has power just fine.
Any other options or troubleshooting I can do?

Using awesome miner firmware, I have a target temperature set of 77 C. My fan runs very quiet, temps creep up to 77, then fans kick on full blast for 3 seconds. Temps go back to 72, and quiet again. Repeat every couple minutes. It's very annoying because I usually have my L3+ running in my house. Can you fix the logic to work like Blissz silent profile (fan will slowly increase speed until stable at target temperature). And then don't decrease speed until there's a delta of 2-3 degrees AND 1 hr has elapsed since last increase (to avoid constant changes in fan speed). The key is reducing changes in fan speed as this increases perceptible noise (your brain drowns out white noise perfectly unless it's constantly changing).
Right now the strategy of jumping to 72-77 deg with fan going from 900 rpm to full blast is very bad for electronics in terms of thermal cycling, and bad for airflow since I have multiple antminers connected to same exhaust area (so if one is randomly going to full blast it will backflow to others that are barely at speed). Need them all nice and stable!
Edit:
Did more testing
It appears that no matter what you set your target temperature to, when it hits 77 C, max fan speeds apply and temporarily override everything for 10 sec.
Set target to 80 C, it will only get to 77 before applying max fans, dropping temp back to 72
Set target to 77 C, it will still get to 77 and apply max fans
Set target to 76, it will be ok at first with gentle fan increases, but then barely jump into 77 ...and jump to full blast
Set target to 75, it will be ok most of the time...gentle fan increases to 75-76, and more rarely bump to 77 and then go full blast still.
Set target to 74, it will sometimes overshoot to 75-76, but small fan increases will stop it from hitting 77, so we're always nice and quiet. Adjustments are still +/-200rpm which is noisy and over shoots the low end.
Set target to 70, it makes very quiet, minor fan adjustments (+/- 20rpm), I like this! Perfect behavior. But I wish I could have my system stay warmer (76 C range) with this small adjustment behavior because I prefer slower 76 C fan load compared to to 70 C fan load.
So I think I found the fix: Undo the 77 C hard coded max fan speed. Since the default target is 65, adding 12 to 65 = 77. If I change target temperature, change max fan speed override to (target)+12. So if I set a target of 75, don't start overriding fast fan speeds until it approaches 87.
Hope that makes sense!
Also if fan check is on, the antminer will restart when hitting 77, and the tuning page says "Fan Err! Disable PIC! Fan1 speed is too low 1770 pwm 100". If I disable fan check, the error goes away and no restart happens. Very weird since this shows up when fans go faster.
Can you please let me know the configured temperature for "Chain disable temp" (the overheat feature)? Please also try to increase this value. The firmware will try to make sure you are at least 10 C below this temperature and can increase the fan speed if needed. By increasing this temperature limit it will be less likely you run into a high fan speed. I had Chain disable temp blank (so default 85). Changed it to 95, but still having same problem. I set target temp to 77, it gets to 78, fans go on full blast for a few seconds, it's then at 72, fans go super low back to 900rpm, then it creeps back up to 78, fans go on full blast again. Thanks for the update. We will use your feedback and comments for future improvements. As for today, there are not really any additional parameters to play around with other than those you already used. Any updates on this fix? The bug is harmful for silent setups because the fan is constantly going to Max at the wrong temperature. This is what my settings look like:  But fans go to max at 77 C, which over corrects temp back down to 70 C, and temp never gets to 79. Also, if I set a manual fan speed, the fans still go to max at 77 C. In that scenario I don't want max to kick in until something like 85C or whatever I set the overheat protection to. |

Anyone else having problems with awesome miner firmware 3.8.6 on an Antminer L3+?
1) Quiet fan mode on startup straight up doesn't work, fans run full blast on reset
2) Autotune does not restart the miner on the "Restarting..." phase. I have to manually reset to get it to finish.
3) Antminer restarts for no reason every 2-12 hours...nothing in the log, tried every combination of settings, voltages, freqs. Even worse with quiet fan mode not working cause some of my miners are inside.
I used to run the Blissz custom firmware and did not have any of these issues. Support claimed no one else was having these issues, but it's happening on each one of my 35 miners. Can someone with an L3+ verify that they also have these issues?

I can't remove groups under my miners tab. Remove Group is grayed out for every group when I right click the name, even if it's empty with no miners assigned. I'm not trying to remove the default My Miners group, just others.
Screenshot:
Are you sure this isn't the "My Miners" group, but renamed and moved to the bottom? For the "My Miners" group - Even if you remove all miners from it, rename it and make another group default - you will still be prevented from removing this group. Is this the only empty group that cannot be removed? Every group. Every group I try to remove has "Remove" grayed out. All groups with miners will have "Remove" disabled. The only time a group with no miners have "Remove" disabled is if it's the "MyMiners" group - even if you renamed it. Can you please try: 1) Move the miners from another group you have, for example "top 6-pck", to the group "not". Can you now remove the group "top 6-pck"? If that's the case, "not" was the renamed "MyMiners" group that cannot be removed 2) If the above failed, what happens if you create a new empty group, can you remove that one? Ok, that worked thanks. That's very un-intuitive, maybe could use an improvement (or inform the user why remove is grayed out). Also, you can't drag and drop miners into an empty group. You have to manually change one miner's group by right clicking and assigning to a group, and then it will let you drop the others under it. That could also use improvement! |

I got one, and even though it's rated for 12kw heat dissipation (15 L3+ antminers), I'm finding I can only run about 8 in there before they get too hot. It seems like they are re-breathing the hot air, and the rear cabinet exhaust fans don't keep up with the volume of hot air pushed to the back. I tried blanking, but there's just too much air pressure pushing into the back to contain it all, it always pushes its way back to the front. Anyone had success running more than that in one of these cabinets?

At 800W per unit, I'm looking at 28.8 kW total. 100,000 BTUs of heat. I have plenty of space in a second detached garage so noise isn't really an issue. Here is my current plan I've been refining over the last few days, looking for input: RackGreat Lakes 45U, 30"W, 42"D NEMA12 Server Rack Enclosure http://www.server-rack-online.com/gl840n12-3042-ss.htmlI like it because it has removable top and bottom exhaust plates. So I'm planning on attaching an exhaust hose to the top port with a 2000-4000 CFM fan, routing all the hot air up through the attic to the outside, or to a window port, whichever works out better. 45U is more space than I need, so I could go smaller. Power supplies18 of Bitmain's APW3++, each one powering two units. I'd like to connect the APW's to one three phase PDU ( https://www.amazon.com/PDU3XVSRHWB-3-Phase-Switched-28-8kW-Vertical/dp/B00KKT2FTK/ref=sr_1_1?ie=UTF8&qid=1504448214&sr=8-1&keywords=3+phase+pdu) if my electrician can get 3 phase power to my garage (I live in the US suburbs). Or more likely, I will use three 240V 63AMP PDU's: https://www.terapeak.com/worth/ibm-dpi-c13-enterprise-power-distribution-unit-without-line-cord-39y8941-server/142173082013/ . That would require installing three 240V plugs and breakers rated up to 63A continuous. ClimateSince hot air is being pumped outside, ambient outside air will be coming in, which is usually 40-80 deg F during non-summer months. During Jul/Aug it gets up to 100 F during the afternoons. The garage already has one wall mounted AC unit which should cover that, but if it's not enough I'll have to install additional cooling units. Thoughts??? |
