ORICO USB 2.0 7-port hub
https://www.newegg.com/Product/Product.aspx?item=9SIA1DS5528295
^
_edit_ One of these hubs literally went out on me the day after this post. The voltage regulator went out and almost lost one of my miners. Total run time aprox 4 months @ about 1.5v / 200Mhz.

Finally showing my first return. BTC
-----------------------------------
The ORICO hub is only good for 2A which will support the miners up to about 225Mhz. Currently I run @ 200Mhz for better up-time. [Correction] 6' o'clock position is about 1.5V. Tuning each stick to .695 volts is about the best for a 2A USB hub.

Some things upon reflection:

*Hourly reset of Raspberry seems to work out the “frozen kernel” issues.
( sudo shutdown -r now ) *crontab for root user*

*A startup script to kick off a separate terminal window for the Miner.  
\/\/\/\/\/\/
lxterminal -t Mining -e bash -c './cgminer -o stratum+tcp://mmpool.org:3333 -u User -p abcd --gekko-2pac-freq 200 --verbose --widescreen'
^^^^^^
#The above command starts the terminal, names it and initiates command.

Currently working on a way to power cycle the devices instead of physically replugging them.

If your miners are each tuned to supply enough power for a specific frequency you can run for months before needing to change anything.
-edit- ^
Except now buying a new USB hub. The above ORICO hub is half the cost but not if you include the cost of a new miner.

ahh ok i see thanks. so the freq setting becomes part of the cmd line that starts up the miner. its not located somewhere in a file that is referenced by the miner.

thank you for the explanation. this has given me something to play around with.

Note how, in the run syntax, it gives you a sample command line to start. You edit this with your own pool configs. Note also the --suggest-diff parameter. Then note that setting frequency is --gekko-2pac-freq; does it look a bit familiar? Try adding that to your command line but change the number.

And if it still doesn't work, go read a tutorial on command line interface and try again.

Like I've been saying for over a year now, the answer to just almost every question ever asked in this thread is "read the first post".

thanks for the friendly response. i already landed on the first page on this thread before posting and i felt like i could not find the answer i was looking for. so by posting here i was hoping to someone i could engage in a conversation as there is bound to be further questions that i'd like to ask.

if new comers like me irritate you, why do you bother to reply at all?

i cant see on the first page that frequency is mentioned like so:
--gekko-2pac-freq 150

but i'm not sure of how to use this in practical terms. i mean... i was expecting there to be a config file to edit or something.

If you don't feel like reading the first post, or any of the rest in this thread, try this: http://lmgtfy.com/?q=frequency+settings+gekkoscience+2Pac. The first option is usually the best.

hi sorry if this is a silly question but what file holds the OC/frequency settings? i cant find anything and i'd like to try and tweek it up a bit

zac

i now have purchased a futurebit moonlander 2

is there anyway to get 2pac and futurebit to work on the same box?

i have a win10 x64

cheers

Too bad searching FAQ section of the first post for "OFF" or "voltage" doesn't turn up references to an illustrated graphical guide to setting the voltage. Also too bad there aren't charts in the first post that give you suggested voltages (and expected current draws) for given frequencies like 250MHz and 150MHz.

The answer to just almost every question ever asked in this thread is "read the first post".

Believe me @sidehack, I did search to avoid such answer.

Now even after buying a good powered hub the 2pac keeps going OFF even after few days of running perfectly, with 2 fans directed on the single 2pac being used, I did try all sides of the voltage knob and yet I still get OFF issue!
Isn't there a more illustrated graphical guide to setting the correct voltage?

Or how do I detect the current-voltage needed for the 250Mhz or 150Mhz?

Is there a way to search for answers to what are likely common problems asked anytime in the 14-month history of this thread?

Yes there is.

A way to search for answers, I mean.

For your question, no you pretty much have to pull the stick. Might be possible if you know which points on the board to short across and jump-start the string, but it'd only work right under certain conditions. Best to just pull the stick and re-insert.

is there a way to revive the 2Pac in OFF mode without removing and putting it back?

That's great, but tech support doesn't really care. Maybe you should mention it in the sales board.

I have 11 2pacs, want to sell. They are 2 months old, will sell for 35 euros each.

This is so frustrating. Lol. When I add dwc_otg.speed=1 into the cmdline.txt my keyboard goes dead but my USB mouse still works. And my USB hub still isn't detected. I wish I learned all this stuff when I was a kid so I wouldn't feel like such an idiot now.

Checking it now. Thank you.

USB2.0

Have you found the USB thread?

USB2 or USB3?

My mouse and keyboard both work it just won't recognize my powered usb hub for some reason.
