before buying new fans you should try to fix the ones you have.

carefully take the sticker off the back and using a needle poke the rubber o-ring that holds the shaft in place and take it off.. the easiest way is to do it the long way and just push the needle straight through it. dont worry about breaking the o-ring, you dont need to put it back on.

then just pull the fan apart, using some white lithium grease put it back together..

ok will try that, but would need to buy some white lithium grease, which i don't have, will this do https://www.amazon.co.uk/gp/product/B00W6Q3B7U/ref=ox_sc_act_title_3?smid=A3P5ROKL5A1OLE&psc=1

Thanks

yeah thats the stuff, its multipurpose so you can use it on anything.

That can't be your problem.  Both of mine say 63 cores in the log.  I never checked this day one but I am running 796 clock and hashing at about 4.45 or so per stick.

jstefanop, 0-63 = 64 cores?  You sure you did not mean to say 63 not 64 for the log output?  Hard to believe both mine are exactly 63 cores in the log?

Everything is answered in this thread Yes the printout is 63, it counts from 0. The normal hashrate = 5.66*clockspeed (page 1), meaning that 796Mhz gives ca 4.5Mh/s, which is what you get and there is no miracle in it. 

Much lower than expected hashrates, very often somewhere between 2-2.5Mh/s can in many cases be traced back to power-supply issues. jstephanop has some theories on exactly what happens in the ASIC (somewhere in this thread). Out of personal experience, I would say that from 800Mhz and up you just have to try and play play with the hub and pot settings and temperature to find a good and above all stable setup. As I wrote earlier, I have a whole bunch running at 924Mhz and some others at 856Mhz or something like it, but it took me while to get it exactly there. 796 was a piece of cake.

This owning two and playing.... I can agree with

But jstefanop did say the log should say 64....  So lets be clear for people...

checked all four of mine and it say's 63 for all of them

Almost all miners & logs list cores/threads/GPUs/ASICs with 0 being the first unit.  Therefor as 0 is the 1st.  0-63 = 64.  Count them.

Yes sorry should have been more clear, the log starts count on core #0 so if all 64 are good it will read 63 in log output.

I was running Moonlander 2 for a couple of weeks, from internal USB of the laptop and had stable 4.7MHz/s speed at 832 freq.
Now, I got a good quality 2A USB hub. I put the core voltage slightly up and frequency 852. For a couple of hours it gave me speed of 4.9MHz/s and then stopped. I put the voltage back to previous position but now, no matter what frequency I put I get a speed of 3.1-2.4 MHz. Anybody knows how to check if I damaged the device? E.g. is there a way to check number of alive cores?

Thanks!

Put "-D 2>log.txt" at the end of the bat command. Start it up and it will spit out the log.txt file in same directory. In there you will see startup sequence and it checks for number of active cores. Should say 64.

Thank you for reply! It finds 63 cores. So one dead core. But it used to give me stable 4.7 MH and now I can't go higher than 3.5 MH. Could there be another reason?

Sounds power related, also try turning up your memory voltage to around .9v, this sometimes helps with stability.

[jstefanop]

Thanks for giving the little guy a chance.

 

Thats why this whole project exists

I have a question, I just went to adjust my voltage pot and the damn top part came off. I was wondering what pot was used on this so I could buy one and replace it.

Also could I just use a 1.5 ohm resistor in order to get the .75 Volts, and what solder points would I use for it if I could. I imagine one of them is one the core voltage probe point.

How did you manage that? These pots are pretty good with abuse, but either way all it takes is a very small screwdriver and some very fine and lite movements to change the voltage. Im assuming you went crazy on it and turned it way more than 180 degrees.

Pots are no where near 1.5 ohm...top one is around 5k and bottom is 100k if I remember correctly.

Hey man, do you know if there is any way I could stick say a 50k ohm resistor somewhere in order to just set the core voltage to stock permanently? Thanks in advance man.

[NoobsGalore]

Anyone in the US, any hints on what hubs can be found for under $100 to work with a few of these? 

there are a heap of tplink ones on ebay that will take 4 at least (its actually 7 port but size nall you know)?

How long will take to make ROI at 3.5-4 Mh/s - 1 stick?

[TimBuck2]

Off topic and irrelevant.

Yes maybe is off-topic and irrelevant.

Anyway is there a lifetime of sticks if i run them at default settings and in a cool space ?

Why i ask? Because i want to buy more MLD2.

And will be in future a MLD 3 created with more speed ?

Lifetime on default settings with proper cooling should be on the order of years.

Hello,

I have raspberry pi 3 and moonlander 2. I follow the steps of comment #16 of this post.

I run start_moonlander2.sh, connect well to the pool but the devices not found. Some can help me? I don't know what is the problem

I connect the moonlander directly to the USB of the raspberry pi.

I need to install UART VPC Driver or this is only for Mac and Windows?

Thank you for all.

[FIXED]

When I install raspberry, I remove pi user and create other, the problem is about the correct permissions of this user

[djalmasantos]

I got a powered hub and put two sticks on it now I get the error Failed to sanity check in lowl-vcom.c windows_usb_get_string():508 but it still seems to work, just not always right away, sometimes I have to start the program several times before it sees both sticks

[thestockfadi]

Can someone please help me figure out how to send my miners to 1 or more coins at a time? Currently I can only mine 1 coin at a time. I was hoping there was a way I can set 1  or 2 of my sticks mining different coins at the same time? Is this possible?

This has been covered multiple times here. You need to create two separate bat files specifying which sticks and which pool you want run with each bat file, and run two or more instances of bfgminer at the same time.

there are 63 pages on this thread .. Most of us are newbs. . at least a link please? or something I can copy & paste?

[thestockfadi]

When I make a new .bat file

bfgminer.exe --scrypt -o stratum+tcp://us2.litecoinpool.org:3333 -u Thestockfadi.moonlander -p 0420,d=128  -S MLD:all --set MLD:clock=832
pause


and when I change the "MLD:all"  to MLD 0 or 1 or 2 or whatever. . nothing happens when I start the new bat file . .
