Sucks the difficulty of Litecoin has gone up so much.
When I started I January with 2 Moonlanders I was getting .00064 a day not it's down to .00044

 Sad

I just received my device, followed the instructions... No device found...   I'm seeing people with "no device found" on here so I checked my recent windows updates (running windows 7 x64) which one should I roll back ? the only ones I'm seeing are MSE security updates, and a "monthly quality rollup" ??

does the device need to be in a special powered USB hub or are the regular USB's on mobo and case good enough?

seems to be a solid chip, will be extremely happy to get it hashing and plan to buy a few more

Make sure you downloaded the UART driver from silicon labs. To check if that loaded correctly go to your devices panel and you should see it under a COM device...otherwise something is going on with the silicon labs driver.

I got mine running on the new Windows update using the older generic silicon labs drivers.  
Uninstall the drivers and re-install these from the web site  v6.7.5.
They will no longer be listed in device manager under COM ports and "moonlander2".  
They will be listed as Silicon Labs CP210x USB to UART Bridge (COMx)

I just installed the Windows 10 update 1803 and after install the Moonlander2 drivers did not work.
In device manager it listed the Moonlanders but had a triangle.
BFGMiner when run says "No devices found".
I tried reinstalling them, removing them and reinstalling but to no avail. The driver Preinstaller program fails with an error.
When I try to manually install the drivers, the error says INF file invalid.

I downloaded the v6.7.5 version from the driver page and they worked!
In device manager under COM ports it no longer lists them as Moonlander2 and instead lists them as Silicon Labs CP210x USB to UART Bridge (COMx).
BFGimner now sees them Smiley

Just a tip should you run into this.

New to this coin.  I have mined about 10 coins with my Moonlander 2.
How do you stake your coins?  Just leave the wallet running?
Not interested right now in a staking pool as I just want to know how it works?
Again n00b here Smiley

Thanks,

Hi there J,
So is there any way to return one of my MLD2's for repair? The raised black thing next to the heatsink labeled "L1" on the circuit board just under the "der" of Moonlander on the board.
Any help would be appreciated.
Thanks Huh Huh Embarrassed Embarrassed

And the heatsink is damaged....just noticed that upon closer inspection and it appears that my dog may have gotten to it, which answers a few questions for me.  If at all possible to fix please let me know...and if it is even worth it...

My dog ate it....  LOL....
Sorry this is too funny!

Edit 2:
With some messing around i think i've found the culprit. One of the sticks was drawing 3.7 amps at 5v!! Even while running at 600mhz for a test it went over 3.58amps. Guessing this one is defected Sad Core voltage and memory both are at 0.8-0.82. This stick won't hash above 2.6-2.68MHash, so i'm hoping bitshopper.de has some sort of warranty for DOA sticks...

You can put a command in the command line that turns on the log.  In the log it will state how many cores are good.  63 is the correct number.  Check that stick and see how many cores are working.

Per the boss Smiley

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.

It is 0-63 so it should say 63 not 64.

Your welcome! Have you tweaked memory voltage as well? And what hub are you using? As you've probably noticed by now, these MLD's are at the top of what most hubs can deliver. Especially if using multiple MLD's. If the hub is not powerfull enough, you can get these errors. That's what i don't get at the moment with my updated mine, the 2 slow ones are just, SLOW... But not to many errors! Still, gonna swap the 120watt powersupply for a 150watt powersupply and see if that fixes it all. Or if i need to use a 2nd hub and that the DC-DC converters in my hub, in the end, just are not strong enough.




I have a 6 amp brick PS running 2 MLD's.  It's handling it fine as the voltage on the buss of the hub holds at 5.1v.
It's possible the 5V has ripple or noise since it's just a cheap brick PS.
The error rate is related to clock speed as at 832 I am below 1% error rate.  at 852 it's over 20% error rate.
Even if I try this with one stick same thing. Core set to 8.2V doesn't help.

Yes I set mem voltage as low as I could go per the info on page one until it would not hash.  Then went up till it did.  Running .76 memory as I recall.

I might get a more solid clean PS and see.

Got these in just in time today Smiley


2 are running slower than the others. Will check tomorrow with a different power supply and or an extra hub to see if that is the issue.


WOA!  Getting serious now aren't you....

ps; damn it took me long enough to put 1+1 together haha, Finless Bob Smiley Pleasure discussing these things with an android mod legend Cheesy

LOL....  Not many know that Smiley

FYI, I am mining coins using some Android boxes moded to do so.  Smiley

Bob

Lol, that was actually my next question! If you were mining on android hehe Smiley which boxes are you using?

Im still using your modded android on a mk908ii stick Smiley

FYI, thanks for the voltage... unfortunately mine are not so lucky.  I stopped at .82V and still get too many errors running above 832.

I have 5 boxes all mining.  The Rockchip boxes do better because they have more cores and faster clocks.  The AMLogic boxes are not so good at it. I stripped the ROMs to nothing (apps and services) and I get about 40 H/s per box mining XMR.  It's not much really but as you know these are super low on power and I just leave them running non-stop.  They add to my PC's hashrate in the end.  The old boxes would basically be sitting collecting dust till now Smiley

Got in a multimeter todat, will try to get some readings tomorrow! My guesstimate would be around .85-.87

Thanks!  Will be interesting to compare notes....  I have just been too timid to go up in voltage much more.  But now that I have some nice brushless USB fans, I am ready to try Smiley

Bob

Can you link your fans?

You bet!

ScoobysportD, so what is your average Vcore voltage to run them that high?
I can not seem to get past 832 clock on both mine with a good PS and fans keeping the rear heat sink cool.
When I get to 852 I get too many hardware errors (30% or so).  Vcore I have tried up to 8.2 but did not want to go any higher.  I assume you are runing higher than that?

Thanks,
Bob
14  Alternate cryptocurrencies / Mining (Altcoins) / Re: Official FutureBit Moonlander 2 Driver and Support Thread on: March 02, 2018, 05:07:48 PM
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 Smiley 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 Smiley

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

Bob, Reckon thats wobble caused by buffeting from the air and disconnecting the usb's. Try standing the moonlanders vertical in a hub with the fan down on top. This cools both sinks and stops any undue force from one side.

No it's not.  The fan is not connected to the hub.  It is connected to an totally different mini-PC box under it's own power. Per the video!
Vibration is in no way attached to the hub running the moonlanders and in no way is vibration getting to them.
The moonlanders look like they are floating but they are resting on grey foam and supported. It's not vibration.
It's pure electro-mechanical noise.  I can repeat it at will.

Check this out!

So I took my wife's cheapo USB fan to help cool the back heatsinks.

The video is self explanatory!  Electromagnetic noise can affect these (or my hub).

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?

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?

Your opinion please on temps.
... I use a heat gun probe tool to measure the small back heat sink and it runs about 153F.  Knowing chips a bit 153F is OK.
... BUT the back heat sink runs about 162F.  I think this is pushing it no?  
Is 162F OK for the back heat sink?  What is the max temp on this to be careful of reaching?  Back in my old chip days 175F was about it before stuff starts losing a lot of life big time.

Back in the old days people read the instructions first Smiley -- see page 1 of this thread:

Even with a fan built in, you can still overheat your Moonlander at higher frequencies. I do not recommend running these past 800mhz unless you can closely monitor temps (if you have a IR temp gun check the top ASIC heatsink, it should not be any hotter than 80C).

Everyone using these beyond 800Mhz uses external cooling (fans). 162F = 72C which is getting borderline, 153F = 67C is really hot. I am running at around 35C = 95F.



My bad...  I missed this one line. And yes I have read page one many times.  I just missed the one single line on the temp subject.

"if you have a IR temp gun check the top ASIC heatsink, it should not be any hotter than 80C"

That is 176F and I am far below it at 153F.  To me this seems OK then?  Even at 832 clock and 163F this is still well below 176F.

So why do I need another fan?  I cannot go above 832 clock as I get too many hardware errors (over 10%) on these even cranking up the core voltage.

Bob

80C at the top of the small heatsink translates to about 90C chip core temp. I would not go above this for prolonged periods of time, but anything below 80C is actually quiet cool for an ASIC (especially for scrypt ASICs, since they don't have a very large compute die). I would not worry unless you reading temps past 80C.

The main issue with heat is actually more stress on the mosfets, since these chips scale very badly with heat (current draw reaches exponential curve as the chip temp goes up). Your most likely to fry the mosfets/cause a overheat buck shutdown than kill the asic. 

Thanks, this is what I thought and why I asked. Smiley

far below?? well below?? Seriously, all that is given is that the chip hasn't fried itself, just yet. Good luck! You are operating at the edge of it's operating range, and while 153F is within limits by all accounts it is seriously hot. 176F is not a safe operating limit, but a potential fry and die limit. You also have to be aware of changes in ambient temperature, if the ambient rises, so goes the chip temp. In general, even if it runs, you will shorten lifespan if it gets that hot over long time.

When you are overclocking you are on your own, and you want to do everything reasonable to keep the babies alive. Alive==cool. 832 == overclocking. But yeah, it's not that you MUST have cooling. But you should! jstephanop wrote a good comment on this a few pages back, when one guy had 8 MLDs running at 5.5Mh/s or thereabout. You should read it. I run at 924Mhz with about 0.7%HW and ca 45C core. AND extra cooling (usb fans).  Some ppl remove the stock fans --> you are on your own, even at normal clockspeeds. 10% is way too high at normal clockspeeds. You should have less than 1% at 600Mhz.


I did not say I get 10% an normal clock speed.  I am below 1% at 796 but above 10% at 832.  Even when they are ambient and I start up.  So it's not heat related I get 10% at 832. It starts above 10% and stays that way.  And I have tried increasing core voltage to .85 and still get that.  PSU is 5 amp. Anyway I am running at 796 just fine on both sticks. Good enough for me.  And yea in my first message I said my ambient temp of 75F during the day thus running 153F at the hottest at 796 clock. Obviously at night I am running less than 153F (about 145F).

I will consider your extra fan but reading jstephanop note, "they should run fine up to 800".  And I am able to get memory voltage to .73V no problem.  Core is running at .75V

I have a friend with a machine shop and he could easily make a larger rear heatsink (longer fins) but it doesn't look easy to remove the existing heatsink.
