so you want to make a .sh file (shell script).

first line is always "#!/bin/sh"  (a.k.a hashbang then the script type.)
Then you include the command you would enter into the terminal on the next line.

obviously, it can get a lot more complicated, just like batch files, but that's the first step.

simple example:  run.sh


after you've made your .sh file, you need to make it executable.  the command for that is "chmod +x run.sh", or if you have a GUI, you can right click on it, and on one of the property pages you can select to make it executable.

then to run a shell script, you need to type in "./run.sh".  the dot slash is critical.

So I bought a new newpac (GSH 10031154) on amazon from "BitMinerJoe".  Literally received it today a few hours ago.

Plugged in, zadig'd, test script set to stock speed of 100.
doesnt work - 0 chips found.

unpluged many times - no luck.
tired on linux, same issue.
also tried tightening the heatsink screws.

checked vcore - 0.0V?  Yeah... that might explain it!
At least I assume I am checking vcore correctly - from the GND pin on the USB to the orange component next to asic #2 shown here:  (Its how I checked on the 2pacs...)
https://postimg.cc/wyhHqSBh

tried adjusting vcore from stock position to 6 'o-clock - still getting 0V.  

Should I return it, or does someone have any other ideas?
EDIT: nevermind, i'm just returning it...

Nope, not without changing a lot of code in cgminer.

Your welcome!  Hope it helps others too.

Yeah, I’m the one who asked for the serial number targeting added to the cgminer code.

Sadly, there is no current way of setting multiple frequencies to the same type of asic in once instance of cgminer. So here’s what you do:

Get your serial numbers.  You can verify them with


then open usbinfo.txt and look for the following section(s):


Take your normal cgminer launch command and modify like this to include all 2pacs you want at the same frequency:


 --gekko-2pac-detect only finds 2pac's.  The --gekko-serial will only find the serials listed in the format shown above.  Yes, that hyphen in GS- is critical.

Make another script for units you want at a different frequency:


This will find the rest of your 2pacs (no serial lookup) and run them at 200.  You would need to start this script after the first - unless you want to specify all your serials like this:


For the newpac:


You can combine these as needed as well - combining newpacs and 2pacs together, as well as compacs and terminus in the same manners.

Example:


This would run the selected 4 sticks at: 200 if it’s a compac (GSC 10000058), 250 if it’s a 2pac (GSD 10019358, GSD 10021759, GSD 10021553, GSD 10021581) or 425 if it’s a newpac (GSH 10030095) (with newpac-boost for pools that support it).  Note that the --gekko-xxxx-detect options aren't needed here, unless you also had a terminus connected and on its own cgminer instance, but they can be useful depending on your setup and how you want to group together devices.

Here are all the flags you can use:

For detecting only one type of gekkoscience asic's:

--gekko-compac-detect, --gekko-2pac-detect, --gekko-terminus-detect and --gekko-newpac-detect

For setting frequency:

--gekko-compac-freq, --gekko-2pac-freq, --gekko-terminus-freq, and --gekko-newpac-freq,

For ramping up frequency over time on 2pac & Terminus (not supported on Newpac. The Compac hardware itself supports it, but the code needed for it isn't enabled in vthoang/cgminer yet. (I sent a pull request for it though!)):

--gekko-start-freq 25 --gekko-step-freq 6 --gekko-step-delay 30

(Starts all supported units at 25MHz (minimum), and steps up 6.25MHz (6.25MHz is the minimum step) every 30 seconds until it reaches the --gekko-xxxxx-freq.)

Serial lookup:

--gekko-serial "GS-10019785,GS-10021212,GS-10033333,GS-10033334"

But anyways, Here is what I use right now (I have a troublesome 2pac (GSD 10019785) separated out for testing at the moment - I have been able to get it stable for 2 weeks now at default stock speed and stock voltage - though still with a solid white light.  It won’t take any overclocking over 125, but at least I don't have to underclock it to 25 anymore!):

First script file:


2nd script file (a mix of 1 compac, 4 2pac's and 1 newpac.):


miner_conf.json contents:


Yeah, I’m lazy and haven't set up that single 2pac for a fail-over to solo.ckpool!  Not that it’s really needed for a single stock speed 2pac though!
Also, the serial for the compac and the newpac isn't needed - since I only have one of each.  But I plan to change that in the future - at least the newpac!  

One other note: Yes, I use "--suggest-diff 1" - my mix of 6 stated above has ckpool auto-correct it to ~112, and the single stock 2pac to ~7.  (32 (the default suggested for ckpool) on the stock single 2pac will still work - you just wont see as much activity)

TL;DR:

figure out your serial numbers, and what frequency each should run at.

take all the identical ones and group them together.

combine groups of generations (compac, 2pac, newpac, etc) into one command to reduce the amount of cgminer instances (if desired)(example: [3 newpacs @ 400, 3 2pacs @ 200, 5 compacs @ 150], and a separate script with: [1 newpac @ 500, 6 2pacs @ 250, 1 compac @ 250], etc.)

profit!

quick question:

I haven't played with it yet, but i just discovered


is the default setting in cgminer.  I looked though this whole forum topic, and nobody has mentioned it - only using the potentiometer to adjust vcore.

should i adjust it higher to get a better overclock?  was it only for pre-production newpacs (i.e not valid for production units)? ...etc?

...and I just remembered that the frequency scaling stuff doesn't work on the Newpac.  (I assume its a Newpac?)
*slaps forehead*
Not sure why the serial part isn't working though.

but yeah, if its only showing one chip, that's a bad sign.  good luck with your return/replacement!

2 things to try:

• adjusting the voltage knob on the stick
• underclocking the stick

I had a 2pac that I had to underclock.  I found that it was stable for about a week with "--gekko-2pac-freq 45"  after a while that week turned into a few days, then a few hours.  I went as far down as "--gekko-2pac-freq 25" to try to reach some stability, which helped for a while, but it doesn't last long anymore, so i took it out of service.  but i got months of underclocked hashing power instead of 0 hash from that stick.

Anywho, an example of the command i used for that:


yes, the "--suggest-diff 1" is not a typo.  The pool will kick it up to a difficulty of 3 after a few minutes when running at 25.
Also, concerning "--gekko-serial "GS-10019785" ", the hyphen replaces the D of GSD.  D refers to the 2pac, C for the Compac, H for the Newpac, etc.     Wont find any sticks otherwise, from what i can tell.  Also, change the serial number to yours, of course!
but using the serial number is great, as you can run a separate cgminer instance.  Just start it first so it gets locked out of the 2nd cgminer instance.

If you really want to play around with underclocking and finding that sweet spot, check this out:


This sets our maximum frequency to 100, but starts at 25. after an hour (3600 seconds), it will jump up to the next supported frequency (its like 6.25 or  something, if i remember correctly) by rounding the 1 from "--gekko-step-freq 1" up to that minimum.  Anyways, so for hour 1, it runs at 25, then for hour 2 it runs at 31.25, hour 3 at 37.5, hour 4 at 43.75, hour 5 at 50, ..., hour 9 at 93.75, and hour 10 and beyond at 100.  play with the values as you see fit.  i recommend logging it to a file so you can see when it failed.

I need to play with the voltage settings on my bad stick, so i haven't tossed it yet - maybe my voltage is just too high and needs to come down.  I just haven't had the chance to really play with it.

whoo! Block 559931!!!

Fair enough, you make a valid point - the timing of payments is unpredictable.  (Also, diversification of funding sources is smart.)

Unpredictable enough that I would keep a reserve and not live paycheck to paycheck blocksolve to blocksolve. Keeping a minimum balance (BTC or $) so you have funds to last the 300% block dry spell.  And I would hope that the big hashers are financially smart enough to keep reserve funds!

It really all depends on the situation, but my main point was that we need more hash!

Yeah, we want more people to join!  lol

Getting some more big dogs here helps everyone out, especially if they stick around!  And even with the 5N ramp-up, all those shares get paid out.

I've been inching the hashrate on my Newpac slowly every couple days.  I'm at 450 MHz and getting ~93 Gh/s now.  My goal is either 100 GH/s stable or 600 MHz stable.
Active cooling, and directly powered by a 5V 60A power supply instead of USB's current limiting features.  (EDIT: Newpac has stock voltage set.)
At 400 MHz it was still slightly cooler than the 2pacs and Compac running at 200 MHz I have on the same setup.  Haven't checked at 450 MHz yet, as i just upped that today.

Edit:  seems like it doesn't like 450 MHz. - 400 MHz gave me ~90 Gh/s.  93 @ 450 isn't as good of a jump as i expected.  Upped it to 500 MHz but was getting 41 Gh/s.  getting stable ~98 Gh/s at 425 Mhz, so that's where i'll stay at for now until i can adjust the voltage setting (and confirm temps).

ah yeah... loving the new --gekko-serial option!

Note to others:  my serial is: "GSD 10019785", but you have to enter --gekko-serial "GS-10019785" and change the third letter to a hyphen.

GSH	- NewPac BM1387 Bitcoin Miner

I don't know if this also works for the bitshopperde versions, as I don't have any: BSC, BSD, BSE. (no BSH yet apparently?)

i'm using:


to get a little hashing power out of a damaged stick (White light on, but both chips still work - it just zombies out quickly.)

Setting it at 37.5mhz is low enough to not zombie - at least for 24hrs so far!  Even 43.75mhz zombies out after a few hours...

I've got a quick question:

I've changed some of my worker names, so the old ones are still there, showing 0 current hashrate, but still some average hashrate for the week, etc.

Will those disappear once the avg hashrate goes to 0 (and my total shares gets zero'd on a future payout)?

Or will they just stay there?

I have:
1 Compac
1 2pac
4 2pac Seconds
1 Newpac

All currently running at 150 mhz.

They are on stands with active cooling and the normal USB 5V is bypassed to use a separate 60A 5V power supply.  (I have no power issues from crappy hubs - they get all the juice they need)

Two of my 2pac Seconds are flaky (the good one just zombies often, and the bad one has a solid white light but still hashes about 75% as good as normal and also zombies often), so i would like to run them at a lower speed - they tend to run longer before crapping out at lower mhz.  aside from just running those on a separate pi, is there a good way to target it's serial number or something?

i know there is the --USB command, but as far as i can tell that just picks up whichever one happens to be listed first?

Hahaha, thanks very much!!!

Hey, can I get the measurements of the Newpac?

I know it is exactly 1 inch across, but I cant remember how long the PCB is and how long the heatsink is.

I'd measure it myself, but it will be a few days before I'm at home and can do so.

Whoo! thanks!!

I've ordered a newpac from 419mining on ebay.

I'll send you a PM.

I'm also in the Portland area, but i'm just a small miner with a few GekkoScience 2pacs.

Wish i could afford some beefier miners, as i've only made about $1-$2 total, but I'm broke.

Don't worry, I'm not leaving with my 54GH!!
