I received this one in amongst the others that I received today. All are working fine except for this one. After visually inspecting with magnifying glass I could see the 'L1" (inductor ??) appears damaged.

Question: would that be the reason that the device starts mining and then after just a minute or less, constantly drops out and can no longer be restarted by the driver?

Second Question: Does this get handled by the distributor or possibly yourself, or am I just out of luck on this one?

Thats the inductor casing chipping off..it happens sometimes due to thermal stress during reflow. Its not enough to damage an inductor...if it was damaged it would not work at all. Sounds like that stick just need to be tuned better. Trying lowering voltages/clocks and see if that helps. If not you can return it to distributor for replacement in the off chance that the inductor really did get damaged.

I am having a strange issue.

I am unable to adjust the clockspeed on my miner if I set it to anything other than 800 it fails to hash anything and stops responding
here are my settings
bfgminer.exe --scrypt -o stratum+tcp://poolurl.com:4224 -u bla.user -p password --no-longpoll -S MLD:\\.\COM5 --set MLD:clock=800 --verbose

This seems to be the only setting that works, If I set it higher, or lower it fails to respond. 800 is not even in your list of preset clock speeds. I've adjusted the power, lowered it, raised it, not difference. It is hashing at about 3.4Mh/s with HW:251/.20% in the last 21hrs.

What do you mean it fails to respond? At 3.4mh your defaulting to stock speed of 600mhz. Sounds like your not editing the clock speed correctly?

Well I finally got my ball bearing fans in for the stock replacements.

They work well but they are extremely loud compared to the stock sleeve fan.

They are the same type/brand as the stock fan, just ball bearing, direct replacement.

You probably bought one that is really high RPM...these fans can go up to 15k RPM. You only need about 7-10k RPM to properly cool these. Stock fans run around 9-11k.

would a 8000rpm fan cool the sticks sufficiently at 5 MH/s

I now have 8 not 2

yes, it was plenty. I filled the holes like in your photo. Scraped off as much as possible . Then I cleaned up a square around the holes with a q-tip and isopropyl alchohol.

also, I noticed the new moonlanders have "lines" on the back of the board showing where the heatsink should be attached. Nice touch. Looks like the large heatsink is perfectly centered around the chip on the other side.

Mine are all running strong @700 right out of the box, under .5% error rate, I'll tune them later tonight for MOAR SPEED!

Anyone try Thermal Grizzly on the moonlander 2?

https://www.amazon.com/Thermal-Grizzly-Kryonaut-Grease-Paste/dp/B011F7W3LU/ref=sr_1_1?s=electronics&ie=UTF8&qid=1517072281&sr=1-1&keywords=thermal+grizzly+kryonaut

I'm wondering is 1gram will be enough for 4 moonlanders? My order for AsicPuppy should be arriving soon, and I want to make sure I have enough on hand.

If your putting on thermal material its only to fill in the via holes, please check the assembly instructions...that is way more than enough. Don't put a layer on there like you would with a CPU otherwise the heatsink wont stick and it will fall off and you'll most likely be left with a fried miner.

That is s sleeve bearing. Unless yours are REALLY noisy, no reason to replace with this one.

Ok, I have to apologize for my dumb-assery. Turns out I was splitting the paper film on top of the adhesive. I thought I was splitting the adhesive.... I just had to peel a little more off. Undecided

I'm all good, sorry for the false alarm, and Thanks for all the fast responses... 4 more ML2 are live in the field!

Oh boy. I seem to be having trouble with the small heatsinks. The tape is splitting when I try to pull off the protective layer.

Any tips?

Any recommendations for replacement tape or heatsinks?

umm why are you removing the heatsinks?

He got them delivered in pieces. you need to peel the 2 sided tape to stick the heatsink on

ahh completely mis-read that. Yea, peeling off the protective layer should be super easy. I just peel them off with my fingernail.

Hello,

I have 5 MLDs mining at about 23MH total, so I am doing fine... They are setup on a high powered usb hub connected to my laptop. I setup the BFGminer on my Rasperry Pi (as I want to have that be my permanent solution), but after about 5 or so minutes of the MLDs being connected, the hashrate drops dramatically... to around 17MH/sec. Anyone experience anything like this? It happens very consistently ... when I connect back to my laptop, works fine for days straight...

thanks

I've experienced also wierd behaviour when moved to PI.
In my case the sticks start hashing at very low rate (like 300 kH each, some even shows 0 from start) .. but it slowly keeps growing and it takes few minutes to get into full hashrate. Never notice such behave when using them in PC ports. I assume the issue could be temps. They are now in cold enviroment, so probably need to get warm up. Other idea it's because it runs over wifi now.
But no big issue as my sticks runs steadily for long time. Just wanted to share.

I've heard that to many sticks set with too low difficulty can cause network issues. Are you running them over wifi?

Thanks for your reply... I seem to be having the opposite happening. Starts off strong, and then just dies over about 20 minutes. I've tried wifi and eth, with same results. Brand new Pi that I have tried to reimage with Raspian twice to make sure no OS error. Very strange...

Do you have good fingernails?

If you don't and it sounds like you don't use a fine tweezers.

I have lousy eyes for close so I wore my corrective eyeglasses. I used a fine tweezers and I used this

Try lowering the frequency on the sticks that are slowing down, or increase their core/mem voltage. Next drive release will have additional checks for slow sticks that will be restarted as well (currently it only checks if a stick has stopped hashing).

... I will start up bfg, they all will connect and hash, after about 2-4 minutes it will say Pool 0 interrupted and they will stop hashing.
... what could the issue be? im using bfg for moonlander 5.4.2.
anyone have any thoughts/ideas?

Network connection. There are a lot of google hits on 'pool 0 interrupted' (not related specifically to MLD or BFGMiner).

so you are saying it has to do with my internet connection?

Yes those errors are either related with a pool issue or network issue.

If anyone is having this issue, I have written a bat file that can help you until you get your internet fixed.

@echo off
:loop
start thisismybatfile.bat ...
timeout /t 130 >null
taskkill /f /im bfgminer.exe >nul
goto loop

if anyone see's an issue with this please let me know!

Hello,

I have 10 MLDs on a powered USB data hub. Everything seems to be working fine at the moment... What I am looking to find out is, can I make each MLD a separate worker? Anyone know how to do that (if possible)?

thanks
George

do u mean each MLD mine different coin? or each using different worker name? if its about different coin, u can try check page 45. if worker name just edit like a normal .bat file

No, I mean same coin each using different worker name. XXX.1 XXX.2, etc.

thanks!
