I've been having trouble with the miner's reliability...
So far, I haven't been able to keep it going for more than 4 hours.
In this forum the two explanations I've been able to gather are that either the power supply is too low, or the memory voltage is too low. I'm fairly sure the power is enough, because the miner starts (correct me if that is a wrong conclusion), and even though I've tinkered with the memory voltage it doesn't seem to make a difference. Not only does it not last, but it doesn't last in an unpredictable way - it can last anywhere from 30mins to 4hrs.
Any help would be much appreciated!

Hi I have am having exactly the same issues with my 4 moonlanders, externally powered is polar hub 2.5 amps per port. Tried all versions of changing core and memory voltages, but runs for short time 20 mins- 2 hours and then hash rates crash and the HW errors jump,did you ever find an answer for this.
Thanks

Solution I found was to write a script to restart every hour. Had something to do with a memory buffer, but that was on raspberry's. Not sure how it could equally affect a larger computer.

It can certainly be repairered.

Can you show us a pic of one that is not broken off...or top of the part that did break off?

mouser.com or digikey.com should be able to get the part...then it just a matter of finding someone or having the smt gear to resolder this. It wil be lead free solder.

OP post is one img well detailed..here we go.

V memory Probe Point

thx for reply.

PD:

searching around i found that in 2018 someone had the same issue

Ah ok. Managed to tweak it a little more and it's now settled at 4.2 mh/s and around 1% HW errors, so vhappy. Just don't really know how those final tweaks became effective!

To be honest, not having a whole lot of luck. After about 10 hours if tweaking (not really knowing exactly what I'm doing), I'm getting a consistent 3.8 / 4 mh/s and about .4% HW errors. I don't seem to be able to achieve what others are getting, but perhaps it's just the pool I'm on.

Thats pretty good...

My Moonlander didn't come with the screwed preset as described. Flat edge for both of them were set South West. Too scared to adjust them now you''ve (OP) said there's no limit!

Thats fine, stock settings have changed since those pics were taken, if you see lots of errors you can slowly turn the main voltage pot to the + side and that should help.

May i know does anyone by chance have any solutions for using moonlander 2 on virtualbox ubuntu?
I had enabled usb 3.0 on the settings as well as added the filter for the drivers and moonlander2
When i opened my ubuntu in virtualbox, the device > usb shows a tick on my moonlander 2 too.

But when i run bfgminer, says waiting for devices and also says Segmentation fault (core dumped) . Thanks in advance

p/s: may i know is there a huge difference in result using windows vs linux to mine?

mine was horizontal and after a few weeks it just broke - nothing was touching it, it was just sitting on a table with nothing around it.

Again thats impossible. These are reinforced USB ports that solder directly onto the board with two anchors. You would have to take pliers to it to yank it off. Im sure someone in your household bumped into it and was too scared to tell you Grin

If you want just mail it in and ill fix it for you

You can say that but I can attest to how it was positioned - there is no possibility of someone bumping it where it was placed. The laptop it was connected to sits on a table where the usb stick hung over the table that the laptop rests upon so it was not as if it was hanging out into open space where it could be run into accidentally or intentionally.

would it have mattered which way was facing up? ie fan on the underside or topside? in my case it hung with the fan on the underside.

Nope, moonlander weights 50 grams, would take at least a pound of force to even begin to bend it. You can even tell in your picture that the metal tab that holds it in place was sheered off (ie it was not a bad solder where the tab was not even soldered in place), this would take an incredible amount of force to do, and most likely was a blunt force from the side to make the metal tear off like that.

well i can still validate and promise that no one bumped it. the "table" it rests upon is 5 feet off the ground and is not anywhere someone could bump it other than myself.

That all being said - it was given to me - I was not the original purchaser and when I received it the usb portion was - wobbly - not sure if that is the best word - it would rock side to side a couple of degrees. So, perhaps it was already damaged.

I would welcome a repair if you are still willing to do so knowing that I got it used. If so - where would I send it to?

So has the heatsink fan assy changed? https://www.amazon.com/FutureBit-MoonLander-LiteCoin-Scrypt-Miner/dp/B0781D19S2

No thats an old listing from a reseller that still has the prototype image up. Moonlander 2 is officially EOL, the ASIC for this is no longer in production Sad

So have you tried resoldering it back on?

No - I still need to buy a replacement piece.
