Yes, in fact it is recommended. On litecoinpool.org.

You mean the potmeter! No that's not recommended, unless you have good access and know what you are doing. You need to be seriously careful when fiddling with the potmeters while the Moonlander is powered: if the screwdriver slips and creates a short on the circuitboard it may end as goodbye Moonlander. If accidentally you turn the potmeter too much you may fry the ASIC or damage the potmeter (see page 1). So better not do it, just unplug and take it easy.

So I've slowly been able to get most things working on the Moonlander 2. With that said, why do some "Misbehave" which ultimately won't allow me to mine. What is misbehaving and how do I fix the issue?

An example would be

Yes you can remove the d=128, but I wouldn't attempt to change the voltage with the stick plugged in!

finally something useful. So I can remove d=128 due to litecoin pool, and I can turn the wheel also if the usb stick is attached?

Thank you.

@ethernaly

Have you measured the voltage with a multimeter as instructed?

Error, I read and I turned the screw to increase that value. But it doesn't seems to change something. It seems that turing that wheel not changing the result (alsow because I'm taking attention to not go out of 180° as described).

by the way thank you for your reply

No no, WAY MORE. 2A+, assume 2.5A. If tuned to the best.

Yepp! And that assumes 35A steady!, not at with the PSU maxed out.

If you OMIT the frequency, it will default to 600Mhz. Multiply by 5.66 (see page 1!!) and you get 3.4Mh/s, suprise?!
To make 952Mhz work you better read page 1 of this thread first!!! You must increase core voltage, otherwise the thing won't work, about a quarter turn. Also, the MLD gets seriously hot, so you need external cooling AND monitor temperature. At 952*5.66 = 5.39Mh/s. The best strategy is to increase frequency step by step, monitor your HW errors and increase core as the errors get above 1-2%.  Continue this process. Good luck, AND READ PAGE 1 CAREFULLY

Further, remove the ,d=128  litecoinpool will set the difficulty for you.

Simply changing the frequency with the start flag of 954 will not work. If you read the instructions on the first page of this thread you will see where he explains that the stock core voltage is good up to about 800. Anything higher than that you will experience errors (like you are) and that is when you have to make fine adjustments to increase stability and decrease HW errors.

It is clear that you haven't read any of the initial instructions. Do that first and then ask for clarification on what you don't understand.

sorry I made a typo (because I can't copy/paste from my rig). I'm using -p 1,d=128

by the way at the moment I've 3.5Mh/s, but I've to remove the final part of the command "--set MLD:clock=954"

so I'm using: bfgminer.exe --scrypt -o stratum+tcp://litecoinpool.org:3333 -u test.1 -p 1,d=128 -S MLD:all


If I try to set the frequency (954) I got an error that say something "a problem occur, trying to restart the miner"


Is there a pool for the prohashing? I've to use always bfgminer? The command is similar but with different url?

Must have misunderstood me. I wasn't making the claims. I was instead trying to understand the same thing.

I was saying that the manufactures of that hub said they improved it and "added a 70 amp fuse". They didn't claim that it was getting 70 amps I don't think.

Regarding power supplies. The hub also claims to deliver between .5 - 1.0 amp per port as long as you are using a power supply that delivers at least 35 A on the +5 volt rail.

Although the power supplies I have (not implying that they are used simultaneously on the 1 hub) are both rated at 38 A on the 5 volt rail - I still don't understand why they felt the need to claim the need for the increased fuse, other than possibly for someone using something else to power it such as this 75 amp power supply I have laying over here from my ham radio days.

_______________________________________ Everything Above Here Is Just Me Babbling ___________________________________________


Bottom line: I fully expected that those individual hub ports would be regulated down to maximum of 1 to 1.5 amp even when used with one single device. I was surprised to see it delivering 2.5 A + as well as my surprise that when pushed these things start sucking up the juice pretty good. I was calculating on needing only about 1 to 1.25 amp per port even running them at 5 +/- Mhs

Would I be calculating correct when thinking that at 2.5 Amp per stick with a PS delivering 35 Amp on the 5 V rail - the max I could have on the 49 port hub and still maintain 2.5 amp or so is 14 sticks?

I am playing dumb  but  how does  that hub get its power?

no atx will feed it 70amps at 5volts

you mention 2 550w atx supplies  they don't have 70 amps of 5v.

they may say they have 35 amps each  but they do not have the ability to feed 35 amps 24/7/365

Can you explain how to obtain Verge using this key?

On prohashing it automatically mines the most profitable scrypt coin and you can get your payout in the coin of your choice.

I have a hard time getting 5Mh/s too. Try to get your set up working before you start tweaking.


URL is fine if you are pointing to Europe server. Otherwise, the URL needs adjustment: https://www.litecoinpool.org/help

-p1,d=128 needs a space after -p

Just use -p 1

litecoinpool uses vardiff so you don't need to specify a fixed difficulty. The pool will adjust based on your hashing rate.

I really don't understand how to achieve 5MH.

Using:
bfgminer.exe --scrypt -o stratum+tcp://litecoinpool.org:3333 -u test.1 -p1,d=128 -S MLD:all --set MLD:clock=954


I obtain a fail.

I'm on Windows 10 64bit.


Can you explain how to obtain Verge using this key?

I'm using my 3 to mine on prohashing with a payout of Verge. Doesn't make a lot of sense to mine LTC imo with how little you earn, better to pick a coin that trades under a dollar, stockpile some, and hope it goes way up in price.

I was curious about the amps being drawn on the ML2 running at 900Mhz and 5.10Mhs and today i received a little USB inline meter. To my surprise the sole unit I have right now says that it is drawing about 4.6v and 2.5 amp - did not expect it to be that high on the amperage.

I have a couple of those Blue Block Erupter 49 port hubs and a couple of 550w ATX power supplies. They claim the hubs are "new version" and "now come with a 70 amp fuse" (before it was 50 amp) ...  I was hoping I would be able to run all that I have coming on pre-order on one hub but at 2.5 amps I don't see that happening.

Well cost is the most important, in the end I paid more than 30USD/MLD (that is ca 40% of the MLD price) just to communicate with it and feed it power, this is including shipment and duties. I didn't mind, but that's horrendous. I don't need an industrial grade hub just so feed the babies. The spacing limits the expansion, I have 19 slots but can only use 11. Some people have 7 slots but can use only 4. That's a pain. On the eyeboot the 3 usb slots on the side are actually quite awkward when it comes to space preservation. Above 800Mhz you are likely looking at external cooling anyway. Fans are cheap.  I would think that a 5-port USB unit with 15A supply per unit. would get one quite far, and then one can dailsy-chain the USB ports to the PC. Some time ago, there was a guy who basically resoldered the psu to a low-end USB hub, connecting it to a heavy duty PSU. That is my liking. I don't need all the housing, I mean the MLD2s are plain PCB as well, so just do away with all housing (except for the PSU). Anyway, my thoughts. For me it doesn't change anything, I am not expanding MLD2s anymore anyway.

By the sound of what you are describing windows defender has removed bfgminer.exe, check if it is in the installation directory!!! If not, then there are MANY posts discussing this and what to do (you must let defender ignore the bfgminer directory). BTW, it is ALWAYS good to check that windows has recognized all your MLD2s: goto --> device manager --> COM & LPT ports --> check for "Silicon labs USB to UART bridge (COM ##)" --> there should be one line for each MLD2, each assigned a different com port. If there are none, or fewer lines with this then MLD2s than bfgminer won't find some or all. But I think your problem is that defender removed your bfgminer.exe

I’m having problem with setup of miners on windows 10 laptop. I followed several setup guides, downloaded the drivers, edited my pool address and clicked Start Moonlander 2 file. Terminal opens and miner is not recognized and not auto-start. My terminal screen lists my pool and then after that it says hit key to continue. If I touch any key, the terminal screen disappears. Anyone have this problem? I have tried it several times with different miners as I have six. Any real help would be appreciated.

Thanks,
