Are all those available frequencies safe to run without more cooling? I have no option to measure but "beast" gets pretty hot when I try to kiss it goodnight @796 or more (room temp. never exceeds 20C/70F)...
I'd be interested to know that too. I backed my three down to 700 but the heatsink on the non-fan side is still too hot to touch for more than a few seconds. I have a temp gun, what's a safe temp to shoot for? Stock cooling solutions is good up to ~800 MHZ, after that you get into overheat territory (not to mention parabolic increase in current draw). The buck and ASIC can handle max frequency but I wouldn't run them unless you can measure temperature and its under 80C on the top of the small heatsink (translates to about 90C ASIC core). Anything past that your reducing the lifetime of the ASIC/buck. This will be even worse if you have a bunch of them together (since they are sucking each others hot air). I have FLIR on my lips. Thanks for info.

I remeber something like "...it can go up to 6 mhs if u can cool it....".
I don't see that much. With external cooling and running at the max frequency of 954mhz, both of mine are doing ~5.45Mh/s. http://image.ibb.co/djNA7w/moonlanders.jpg

I have got my moonlander 2 & facing couple of issues, I have connected the USB device to my laptop with clock set to the lowest frequency ("--set MLD:clock=384"). I'm using the low frequency setting until i get my new USB HUB. The issue is the hashing stops/halts after running for few minutes. Below are the two cases i have observed. case 1: hashing stops/halts when it encounters "stratum connection to pool 0 interrupted". I have waited for almost 30 minutes after this last message in my screenshot & it never progressed. https://imgur.com/rpn2FrePlease help me if I'm missing anything here or to tweak anything to make it run continuously without restarts for every few minutes. Thank you. I'm getting this exact same problem on my moonlander2. After mining for a few hours, the stratum connection is interrupted and the GPU hangs. Once I manually reset it, it works fine. Does anyone know for a way to auto-restart bfgminer if this specifically happens? Or know why this is happening? I'm running Windows 7. I hope this isn't the only solution: I'm able to address this problem by tweaking USB port power options. Follow these steps & it should fix your's, 1) Plug in moonlander 2 to the computer. 2) Open device manager on windows machine. 3) Under USB controllers identify the USB port to which the moonlander 2 is connected to. 4) Right click that particular USB port & select the properties. 5) Under the last tab 'Power Management', un-check the option of "Allow the computer to turn off this device to save power". 6) If possible restart the computer & try again. It works for me. Hope this helps...Happy Mining ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Pushing it that hard, with all your equipment (hub, ext cooling), I'm sure u are equipped enough to measure somehow ur temps, because as I undestood it from last few posts, it matters alot. Maybe even with ext fan its too hot (or both of them). I am just guessing. But if you are complaining because you feel cheated somehow because you expected 5.8-5.9 I have no answer to that. Max I saw was about 5.80 on one post showing "simulation" or something like that. I am getting 4.40 @796, one piece, no hub, in 3.0 laptop port and I don't feel cheated btw., but respect everyones questions and feelings.

No, don't feel cheated at all, that's just the most I am able to get out of them. I don't think any cooling problem or I should start seeing excessive hardware errors.

No, don't feel cheated at all, that's just the most I am able to get out of them. I don't think any cooling problem or I should start seeing excessive hardware errors. I am sure under some ideal/lab conditions amps/temps, it can be stable at more than 5.65 but anything over 5 is superb for this small device. I just hope you have cheap energy with that hub/ext fan setup. ![Grin](https://bitcointalk.org/Smileys/default/grin.gif)

Hi!!
Got my miners today...
Issue 1: Starting bgfminer on Windows XP SP3 leads to 99% CPU workload permanently and that´s it.
Issue 2: Same hubs and miners on Windows 10 working flawlessly yet, except a single miner, which shows strange behavior. 480 ist just okay but 540 best result is about 6-7% hardware errors. Very odd is that the errors get less by reducing the core voltage... Lowest possible VCore results in lowest hardware errors in 540. Why? 648 gets not below 25%, also on lower VCore.

In the Power Options there doesn't seem to be anything relevant to saving power on USB ports either.

How can i mine Scrypt-n coins with this? i dont find a miner that works with this usb
I'm using multipool, but it has the difficulty set to 3.03M. If you look at the screenshot from someone also on the system, they have a difficulty in the Kh range. How do I get it lower? I tried the "d=128" in the password, but no. I'm mining LTC. That's probably what it is...

Mine will burn your finger after more than a few seconds and it's reading 48C (118F) on the rear heatsink. I can't even imagine hitting 80C.

No I wish...just the source gets updated on commits. I have to manually compile and test for each platform on each release, which is why this is taking this long. I should be able to post all updated binaries tomorrow.

No, don't feel cheated at all, that's just the most I am able to get out of them. I don't think any cooling problem or I should start seeing excessive hardware errors. If your not running the stock setup I would really check the small heatsink temp with a heatgun before continuing to run them at max clocks. The heatsink is designed for induction flow with a fan blasting air on it in close proximity. Overheated ASIC will NOT show excessive errors, either the buck controller will blow, or your going to burn out the ASIC. There is over-current and over-temp protection on the buck, so you will most likely kill your ASIC before you see anything wrong.

Ok, I'm not sure what the issue is here. I'm running 2 MLD's on my RPi2. It's been running fine for the last 3 days with no issues. Today I got a voltage meter that I plugged my USB hub into to measure the overall energy consumption of the MLDs over time. I stopped currently running BFGMiner, then shut down the pi. Plugged the hub into the meter, and turned the pi back on with the hub and MLDs connected to it, but I can't get BFGMiner to find the MLD's anymore. The result of is below /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=dwc_otg/1p, 480M |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/5p, 480M |__ Port 1: Dev 3, If 0, Class=Vendor Specific Class, Driver=smsc95xx, 480M |__ Port 2: Dev 7, If 0, Class=Hub, Driver=hub/4p, 480M |__ Port 1: Dev 8, If 0, Class=Hub, Driver=hub/4p, 480M |__ Port 2: Dev 11, If 0, Class=Vendor Specific Class, Driver=cp210x, 12M |__ Port 4: Dev 9, If 0, Class=Vendor Specific Class, Driver=cp210x, 12M |__ Port 4: Dev 5, If 0, Class=Vendor Specific Class, Driver=rt2800usb, 480M
also lists the following: T: Bus=01 Lev=04 Prnt=08 Port=01 Cnt=01 Dev#= 11 Spd=12 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=10c4 ProdID=ea60 Rev=01.00 S: Manufacturer=FutureBit S: Product=FutureBit Moonlander 2 S: SerialNumber=xXx C: #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=100mA I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=cp210x
T: Bus=01 Lev=04 Prnt=08 Port=03 Cnt=02 Dev#= 9 Spd=12 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=10c4 ProdID=ea60 Rev=01.00 S: Manufacturer=FutureBit S: Product=FutureBit Moonlander 2 S: SerialNumber=xXx C: #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=100mA I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=cp210x
So it looks like it's there and running. My current start_moonlander2.sh script looks like: ./bfgminer --scrypt -o stratum+tcp://us.litecoinpool.org:3333 -u MyName.3 -p myPass -S MLD:all --set MLD:clock=600 The lights on both MLD's are solid green. Any thoughts on how to troubleshoot, or if I'm missing something? I've restarted the pi numerous times with the MLDs plugged in and out trying to get them to showup in bfgminer to no avail.

Some Googling turned up this: https://askubuntu.com/questions/234691/cannot-mount-see-access-usb-device-ttyusb0Basically it looks like everything is setup, but cannot communicate on the ttyUSB0 and ttyUSB1 'ports'. I did the following with both MLDs connected and then logged out and back in: sudo usermod -G dialout -a username If anyone can explain what would cause this to suddenly stop working, I'd love to hear it. For the moment, I'm back up and running again! =) Anxiously awaiting my 3rd in Jan....

Anyone?
Is there any alternative to bfgminer?
