FutureBit Moonlander 2 USB Hubs Thread

[Eyedol-X]

I got a TP-Link UH720 and Raspberry PI 3 (Raspian) and ran 4 Moonlander 2 on them. They run at standard core voltage @ 796 MHZ so about 4,5 MH per Moonlander. The power consumption for the hole setup is 50 watts.

Interesting hub find, they don't advertise how many amps per port but they do advertise a 12v 4amp power adapter is supplied. Good to hear you got 796mhz out of this setup on 4 MLD2's -- how long you been running this setup?

Hi, for 2 days now. Will see if i could tweak a bit. But 50 watt are quite a lot. I additionally run shortly 852 but one of the miner got 15% Error rate.

I'm running 3 sticks on digitus 10 port https://www.digitus.info/en/products/computer-accessories-and-components/computer-accessories/usb-hubs/da-70229/   ... running fine at 832 MHz ( 4.7 MHs, HW around 1%)

Hub has room to accomodate 6 sticks but you would need to underclock them as the power supply is only 5V 4A.

Hi,

I got some cheap USB hubs lying around. I was thinking, instead of using their wall brick power supply, I would just power them up with SATA standard power cable (I will make my own connector etc). It has 3 pins with 5V, each one should give 1.5A, together that's 4.5A @ 5V = 22.5W. How many miners I can power with that? One or two?

Seems like you could power two with that setup.

Thanks, certainly I will try. Providing that SATA power cable will give real 4.5A:)
In few days I will get started, miners arriving soon so I need to be ready.

I got the sipolar a-400, 12v x 10A = 120 watts. 

If you keep your miners @ ~2amps each, you can slot 10.  5A * 2A = 10 watts.  That also leaves you with a 20% buffer.

If you push them faster, higher, say 900mhz... ~3A.  That is 15 watts each.  15 watts * 8 = 120 watts.  Though I think 8 would be pushing it.  No buffer.

Seems like the most bang for the buck frankly.  The a-200 is only 90 watts(20A*4.5v).... who cares if it has 20 slots, you cant really use them.  Even at 10 watts per stick, you could only get 9 on this hub, and I suspect it would be unstable, because again, no buffer.

Aliexpress has this thing on sale for $45... really does seem like the best bang for your buck.

Ok so if anyone is interested I'm now selling one of those plugable 7 Port USB hubs on eBay in the UK see the link

Sorry i'm new here, I just bought a pi and two anker 13 port hubs to run 10 ml2's but i can't get all of the ports recognized. Only about half of them on each hub work. Is there any way to disable the unusable ports to free up the ones i need?

[aballen]

I hate to tell you, there have been reports of anker hubs having issue with the R-pi, I think it is even mentioned in this thread.

Couldn't get the Rpi to recognize them so i have the anker hubs on a win10 computer. Works great for that...

Boy have I got a story for you folks...

I ordered a bunch of MLDs in November before they were too pricing at $200/each at Amazon and I started to use my rack which has been sitting around for 15 years....finally get to use it.

I went through 4 powered hubs and bought a 20 port Eyeboot from HW (I just got it 2 weeks ago)...One final 10 USB power hub (UNITEK 10-Port Fast Charger USB Wall / Desktop Multi-Port Charging Station ) was working fine until it didn't.  Luckily, I was able to get a refund.  I use these $6 USB power/data adapters which work fine...

I'm just so burnt out in trying so many hubs..that don't work.
I have 10 MLDs with no home yet.

[kcw-grunt]

I'm running ten ML2 on Sipolar A400. Prefer Antminer L3+ but too loud to use at home or work. Don't they make mufflers for these things or something super quiet?

Will it run 10 at 954mhz?

I have seen a few sellers that offer a Antminer muffler box.  you should look into that

Modified Tripp-Lite 10 port hub

Here are some photos of my modified 10 port hub, wire soldered on power
tracks to top of caps solder points.
With the wire mod and 5vdc @ 10amp supply can get 5Mh per unit (Freq=876, D=1024)
This is the max I would set at as cooling becomes a issue and life cycle of chip maybe effected?
Any hub should work long as enough current can be supplied to each usb port to meet the miners demands.

How are you running those in the config?

[sunk818]

I got the sipolar a-400, 12v x 10A = 120 watts. 

I burned through two of these in two months. Was running qty 10 Gekko 2Pac on one. And qty 10 Moonlander 2 on the other. Both were running about 115W according to Killawatt. Both power plugs are positional now (I have use a zip cord to keep USB HUB powered). I had to stop using one because there is a burning smell every time I power it on.

Any other recommendations? This made in China is really hit or miss. Was looking at Eyeboot but anything 10-port related is sold out.

There's a bunch of Sipolar products on AliExpress, but I'm hesitant to buy more Sipolar after two duds within 2 months of buying them.

Anyone tried that kind of ports:

This is just standard USB front, with USB 3.0 cable which goes to motherboard. It will give you only what specification says. Wikipedia says that about USB 3.0 power specs:

Power and charging

As with earlier versions of USB, USB 3.0 provides power at 5 volts nominal. The available current for low-power (one unit load) SuperSpeed devices is 150 mA, an increase from the 100 mA defined in USB 2.0. For high-power SuperSpeed devices, the limit is six unit loads or 900 mA (4.5 W), almost twice USB 2.0's 500 mA.[10]:section 9.2.5.1 Power Budgeting

USB 3.0 ports may also implement other USB specifications for increased power, including the USB Battery Charging Specification for up to 1.5 A or 7.5 W, or, in the case of USB 3.1, the USB Power Delivery specification for charging the host device up to 100 W.[12]

You will get something similar, not more than that.
I tried 2 Moolanders on my USB 3.0 front from my Fractal R5 case. They can work just fine at 756MHz. I wouldn't try anything above that, I don't want to fry my motherboard

Just a quick note for Moonlander folk in UK and Europe - Am currently using this Plugable 7-port hub with x4 sticks, running fine so far: http://[Suspicious link removed]/2zkGMOu

Tried this Orico number: http://[Suspicious link removed]/2jdmoGn failed at more than two.

I have the same setup, you going to try 5x ? Also what speeds you running ?

I'm aiming for 6, 2 more sticks in the post. Running at 720 at the moment, stable, 4MHs per stick. Can obviously go higher, sink temps at mid 60's... Will post what happens with 6!

Ok. I have three more in the post on top of the four I have connected now.  I think it's just a matter of speed & amps that each one draws in order to get all seven running.  From my post on page two if this thread I think (in theory) we have 1.71a to play with per port...

"If you were to split all 7 ports up equally and assuming 100% efficiency you could in theory draw about 1.71A per port."

What we could do with is accurate amp / speed table for these.

UPDATE (and a WARNING!) :  I'm now running 5x moonlanders at clock=756 on the plugable 7 port usb 3 hub and my meter is showing power usage (for the hub alone) at 53.08w, i personally wouldn't like to try running 6x as this will exceed the rating of 60w (12v x 5a) so you're running the risk of overload, over heat / maybe fire etc.  I can confirm it's stable though   Time for a new hub...

I'm running 2 Moonies prefectly on that hub at 852 (4.8 MH/s).  When I add a third, it craps out.  Also, I'm not sure if my kill-a-watt is messed up or not, but it says those 2 Moonies and the hub are pulling 43W from the wall.  When I add the 3rd, It reads 64W.  Those readings seem way to high.  Thoughts?

[cryptochris]

Considering doing something like this, except instead of the barrel plug, I'll cut it off and wire it up to the 5v rail of my PSU. Anyone else try something similar, or make custom cables running beefier power wires? Seems like a good idea, then all the ports in USB hubs could be utilized.

Thanks for the infos.

I just want to find a good hub that can run 4 Moonlanders 2 and >100$ ..  not sure if it's possible
