I currently have 4 at 250mhz on a 49 port with at 300watt 60amp powersupply.

With the USB fan and those running at 250mhz I am using 75watts.


That is not too shabby, I can't wait to get my hands on the pod  since that will be better then what I am getting at 75watts.

Is there a thread for the pod? I have seen numerous references to it and am intrigued.

How did you measure temp on the ASIC chip when they're under the heat sink? (or at least I believe that they're under the heat sink )

The ASIC's are actually on the PCB side (I think). At least that was one of the takeaways I got from this post. As for the temp I just pointed a laser temp probe at (what I think are) the ASIC chips.

Interestingly, the silicon around the chips are considerably warmer than the chips themselves... 

I believe that Dibblah is right when he said that those are capacitors.

In short: only some USB 3 powered hubs can be directly linked to rasp pi (Superbpag is one such known example where it works; USB 2 powered Plugable also works directly with pi, not sure it it is enough for 2pacs).
most USB 3 hubs would not work by themselves (it includes Anker), however, don't despair, there is a simple runaround: use non-powered simple usb hub (like USB2 Sabrent for around $6), connect it to rasp pi, then connect your powered hub to Sabrent, then it should work, providing that you push the button on Sabrent to activate the slot (it should shine blue).

TL;DR either return your USB 3 hub (non-Superbpag) and get Superbpag OR get a non-powered hub like Sabrent and use it as a bridge.

Thanks for this. My USB 3.0 powered hub is made by Anker. As described, it does not work on my Raspberry Pi for most (but not all) devices. I followed your advice and bought a simple (non-powered) USB 2.0 hub and connected it in-line between the RASPI and the USB 3.0 hub. Unfortunately, I'm getting the same result. When I plug the 2PAC into the USB 3.0 hub, cgminer still cannot see it.

At this point, it looks like I'm returning the 3.0 and 2.0 hubs and will try to find a good 2.0 powered hub (but they are hard to find!).

my setup is sticks in Superbpag USB 3 powered hub, then Sabrent usb2 bridge, then pi. Many people use a setup like this.
This is guaranteed to work.

TL;DR why not Superbpag?

Oh hey guess what, there's an entire thread discussing hubs for these sticks.

I know most use raspberry Pi to mine, I have the PINE64 board tested it lastnight to mine with the 2pacs I think it is faster then Raspberry Pi 3 B model I was using prior to it.  It has 2GB of Ram I guess that is why it is faster.  I load Debian Jesse 64bit on this board.. works nice.

I just ordered mine from amazon today. Been reading through this thread. Noob question: If I get a prebuilt cgminer for windows, do I still need to install the Zadig usb drivers?

Yes, Windows will initially install a different driver that is incompatible with cgminer.

raspberry are pretty easy to setup if you follow the directions.  on windows you are wasting too much electric it to run them 24/7

well you would be correct  if you only run  the 2pacs and compacs.

if you run other mining software windows 10 and windows 7 on a pc are fine.

At the moment I run cgminer and nicehash

this give me 1 compac 1 2pac and the cpu mine xmr on the same pc.

the cpu xmr  adds about 10 or 15 watts  ands net a very small profit.

which means the 1 pac and 2 pac   cost no extra on the mobo or cpu power use.

so I do better then a rasp pi but  the pc cost me  $$$ it is a lenovo m700  and I upgraded the cpu

I have one 2pac (out of 20) that when i plug in hashes fine for a while but then goes zombie.  the /var/log/messages and /var/log/syslog just keep showing cp210x converter detected , cp210x converter attached , cp210x converter disconnected. over and over until it crashes my raspberry pi (aprox every 6-10 hours) I have tried different ports and voltages but nothing. The fact that I have 19 others hashing away fine leads me to believe it's the stick but I want ask officially before i bug sidehack (again)

details  are you are freq 150 200 250 300?


did you run it alone  and it fails?

my guess is if you have 19 good  and 1 bad it really is bad.


try  running it alone  for a while at freq 200

sorry I was running at 300mhz at first at 1.51v , then i brought it down to 275mhz at 1.46 , and today I kept it 250mhz at 1.45, 1.42  and 1.41

*edit* I will try it solo next time it crashes

[lanegg]

All four of my 2Pac's won't stay mining suddenly. Earlier this afternoon they were working fine. Left for some dinner and came home and now they aren't detected by cgminer.

I can connect to the Pi and have tried turning everything off, disconnecting them from each other, and turning them back on. I turned off the cooling fan and I can feel heat on the heat sinks building. It has been my experience that if cgminer isn't running there shouldn't be any heat coming in heat sinks. I have green lights on everything but no blue flashes.

I did get the boards to start churning numbers once after rebooting everything. They hashed for about a minute, maybe two, then shut down again. This appears to be a fluke as I have tried again a couple without being able to replicate.

Any idea of where start looking?

Here is what I see if I start cgminer by hand (I usually start it from /etc/rc.local).

We are having similar issues. I have four devices that on the surface appeared to be working but I too would have random crashes on my Pi that would require a hard power cycle (I mentioned this earlier in the thread but I figured it was something I borked so I let it drop). Now suddenly all four of my sticks won't start processing and looking through the log files you mention above I see very similar messages in the logs.

I don't think the sticks are bad, but there is definitely something not right.

[philipma1957]

run 1 stick at freq 150


come back and let me know what the 1 stick does.

run 1 stick at freq 150

No difference:
