While i'm certainly not jstefanop, i think you're 100% right timbuck2! I don't like lying/manipulating clients either.

jstefanop,
                I know this may not be the appropriate thread (not sure) but I am doing this in public so that if anyone else has questions as to the "authenticity" of these devices, they can reference this thread.

                After 30 days of use, a buyer on eBay is attempting to get a return by claiming:

"Doesn't seem authentic"
"this is not the second batch of version 2"

                I am asking if you can weigh in on the high res photos of the devices and explain a little for my own reference in case why these are indeed the latest ML2's that you put out.

I would appreciate you weighing in, please.

Thanks! Useful stuff With the 7 MLD's still in the hub they all get 63 cores. One is slower than the others (slows down over time) though so it still could be a power issue. The 8th MLD currently is not connected so will test that tomorrow, but i've tried that one on a separate hub (even separate computer) which used to power 2 MLD's without issue and with this one it just wouldn't work. Curious to see if on that one all 63 cores are functioning And if so, why is that one running so slow and failing so often, even when on a separate powered hub :S

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

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

Yea supplying power is a finnicky thing with these MLD's I've got a feeling my current issue IS power related as well. If i'll remember i'll also measure the memory voltages on mine MLD's. I have tweaked it a bit but then i gave it a little more juice 'just in case'

EDIT:
Just tested a couple of the memory voltages, ranging from 0.81 - 0.87v

Also swapped out the powersupply of my hub for a 150watt laptop power supply, so far only 1 MLD is slow now compared to the others. If i'd know which one that is i could get some more testing done with a separate hub or something to see if the problem is caused by lack of power or something else...

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 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...

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.

The one i'm using is the one that's in the first post by jstefanop as well, 14-12-2017 according to that post. So maybe there was one released earlier in december that you are still using? I dont really know to be honest. Maybe jstefanop can give some clarity on this?

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 like tinkering :p Once i get everything running exactly the way i want, i'm gonna switch coins weekly/bi weekly or monthly depending on what new coins will come up on scrypt. All together the 8 sticks should provide nearly 41MH/s so if i'm early to mine a new coin it could be interesting and who knows, only one of the coins has to blow up in value Besides that 'gamble' it's just fun and games for me now...

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

Bob

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

Bob

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

Im still using your modded android on a mk908ii stick

LOL....  Not many know that....  
Legend?  I don't know about that

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

Thanks for the voltage... unfortunately mine are not so luck.  I stopped at .82V and still get too many errors running above 832.

Got these in just in time today




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.

and to find relevant COM ports in win go to devices and priters. Right click on each MLD device (i think it's called silicon labs or sth ) / properties .



EDIT:
@scoobysportD
ok, that differs from what I can see.

I notice you have some different version of bfg miner.
my says: 5.4.2.38-g106390a
but yours: 5.4.2.38-g106390a-99  .. ??
( I'm using the one released 12-2017)

I'm not getting that, will take screenshot when i get back home.

EDIT:
This is what i'm getting after pressing M:


edit2: What i'm not understanding yet is why MLD2 and MLD5 are hashing so slow! barely 3mhs. All others function properly. I'm not sure if this is a power issue yet. Once i know which boards are having issues i will test them separately.

Right under the row: MLD 0 (with all the info about hasrate etc.) you should see 2 rows:
FutureBit Moonlander 2 from FutureBit
Serial: XXXXXXXXXXXXXXXXXXXXXXXXXXX  (that's the UID)

I've been trying to do this but i can not see any UID besides the MLD0 / 1 etc

Anything else i should do besides pressing M and selecting the device which is causing problems?

its been stated many times.. you make 2 bat files.. one with -S MLD:\\.\COM1 and -S MLD:\\.\COM2 and one with -S MLD:\\.\COM3 through -S MLD:\\.\COM7.. (change the com ports to the actual ports of the usb)
use multipoolhub for verge and litecoinpool for litecoin.

I use windows 10 64 bit. I want to mine with 2 MLD Verge and with others 6 Litecoin. Can you make a video tutorial for windows 10?

I will send you altcoins ~ 15$ if you can help me

create 2 separate configs or launch scripts and specify which devices to use with:

-S MLD:/dev/ttyUSB0 -S MLD:/dev/ttyUSB1 ... and so on

make sure to remove the -S all

if you're on linux here's a scipt to find out the correct device numbers to use

Maybe someone here can help you, i'd be interested in a quick help guide on that too lol

Otherwise it could be worth to visit this topic:

Also, it's good for people to know what OS you are using
