Topic: Official FutureBit Moonlander 2 Driver and Support Thread - page 104. (Read 71725 times)

Hey there jstefanop, just received my order a couple of days ago, and it seems like one of my miners has an issue where it runs normally for a brief period of time (avg 2-min hashrate of ~4.1 running at 756), and after a few minutes, it ramps down to ~2.7 or so, and that's where it stays. I have two other units that work fine, and do not exhibit this behavior. I've tried adjusting the core voltage a bit (swept the from 0.7 - 0.825), but nothing seemed to have an effect. Didn't alter mem voltage. Another note is that I don't notice this drop when I run at lower frequencies; at 684 for example, all three sticks seems to have a avg 2-min hashrate of 1.75.

Not sure if it helps, but its unit #2815. Any thoughts or suggestions? Got a multimeter in case that's useful. Thanks in advance!

If the driver wasn't working it wouldn't get as far as that screen (it would show no devices detected). It just fails to start hashing due to power/hub issues. If you guys are testing new setups always check on the lowest power setting first (384 base frequency and ~.65v core voltage), then slowly start turning up core voltage/clocks.

Another thing to check on your oDroid is the UART to USB drivers. Make sure they're the latest version.

You are awesome, thank you!. I hardly ever use windows so I didn't even think of it; it was on. We shall see tonight. I'll also try a different hub later today on the oDroid, I really want a nice compact package.

If your windows is stopping in the middle of the night, make sure you've disabled the "Smart" power management for USB hubs.

Here's a guide:

I picked up a hub that can supply 15w (3amp) per port and still the same thing, it appears, but does no work. I'm out of ideas at this point, i guess I'll stick with windows that just stops hashing every night for no reason and come up with a restart script.
Thank you for the input and help.

Got some assembled and up and running.  I'm noticing some are slowing down to about 2MH after running for an hour or so.  Is this a self preservation feature?  Are they running too hot?  I hit all the small heatsinks with my pyrometer and temps are all about 60C.

Received and working without driver download, just installed new bfg miner link for 5.4 you gave and edited the sh file. KDE Neon based on Ubuntu 16.04. I should also mention I'm on kernel 4.9 which is not the official.
Thanks to you and to asicpuppy.com

Edit: Wait, I spoke too soon. It sees the second Moonlander but it won't start the second one. Let me read this thread some more.
OK, read thread. Probably a power issue. So I need to get a powered USB hub

No that’s normal, I wouldn’t take an iron to the board unless your experienced and know what your doing. The thermal material on heatsink is thick enough to compensate for any extra solder on the back.

I got my boards today and I'm starting to assemble them.  I noticed a few of them had solder coming through the vias on the large heatsink side of the pwa.  Can I just grab an iron and a wick to clean these up?

edit:  guess I can't link external pictures...

Yea no way your going to get 2 A out of that thing on a USB port. If you turn down the core voltage all the way, and set frequency to base 384 you MIGHT be able to get to to run like that. At that setting it draws 500ma which should be enough for even that board.

Cool, thanks crushed. Hopefully mine will get here soon.

Yes. I got mine on Friday or Saturday I think. I'm on the east coast in a major metro area.

yeah you cant run these straight from the board.. you will need a hub.. one that can provide more than 1a per port.

Hello,
I am attempting to get this to work on an oDroid C2. It worked great at all frequncies in my windows machine, but id like to get it to work on this oDroid running Ubuntu.
I was able to compile everything and get BFGMiner to recognize the Moonlander 2, but now it won't do any work, i've tried various frequency and voltage variations, could it be I just don't have enough USB current?

This is what im getting as of now:

Thank You

Anyone got theirs from Holybitcoin yet?

according to litecoin pools calc 1 stick that does roughly 4mhs at 756 speed

Expected Time per Block   15663 days 11 hours
Probability of a Block in 7 days   0.05%
Probability of a Block in 14 days   0.11%
Probability of a Block in 30 days   0.23%
Probability of a Block in 365 days   2.76%


so yeah not the best odds..

Thanks I figured so......

you can point it to antpool as solo and maybe hit the spot once in 40 years, or in next 13 mins) but id use ant router for that. there's no competition comparing to L3-like miners, but you can have a lot of fun mining new coins like mut/interstellar/morty/mad/bco/etc..

So I am just learning ASIC mining coming from GPU mining.  This looks like a reasonable little stick.
I know this might sound like a stupid question so flame if you like

What are the odds of getting a coin solo mining?  Like the lottery?  Or better odds?

Thanks,
Bob
