GekkoScience 2Pac/Compac BM1384 Stickminer Official Support Thread

[vh]

Directly plugged in, but I figure the port can't handle it. will go out and look to buy a powered usb hub tomorrow.
It works, ran for nearly 18hrs before it dropped off.

On windows, disable this setting in the advance power options in the control panel if your PC is constantly on, just in case:

So ive done the following and it will run the Green compac I have but does not recognise the bitshopper compacs. Just comes up with "usb init failed"  

did you do the following...

Code:

cd ~/git/vthoang/cgminer/
sudo usermod -G plugdev -a `whoami` #whoami=pi if you did not change it
sudo cp 01-cgminer.rules /etc/udev/rules.d/
sudo reboot

it is right there in my prior post.
I don't see you quoting this.
When I did not do this, I also got "usb init failed".
EDIT: this is only so if you are actually talking about 2pacs. Original black Compac (not 2pac) is a whole another situation that vh is fixing, apparently.

I havent done that part yet as the fiest time i did it didnt seem to do anything just moved down a line woth the same root(?) ~/git/vthoang/cgminer/ without loading anything, so third time round i didnt do it.

But yes i am talking about the single chip bitshopper compacs.

[ppetrovic68]

It's possible VH's driver doesn't recognize the bitshopper product string. Reckon we'll need to get that fixed here directly since I'm working on bitshopper 2Pacs right now.

hmm... yes it is very possible I didn't finish connecting the dots there.  99.2% likely.
I'll add it shortly.

vh, how hard would it be to have "--enable-icarus" and "--enable-gekko" play nicely?

If I'm not mistaken make fails with double defined macros or something like that. If that's the only problem it should be easy to fix, right?

And if icarus driver could be tweaked not to accept Compacs and 2Pacs, that would be great

it does not do something visible, it just allows you to run cgminer executable (./cgminer) in ~/git/vhoang/cgminer folder without the use of sudo, but it is less relevant here since you are not using 2pacs, which i thought that you are since this is a 2pac thread.
Also, you don't need to do this more than once, of course.
Nevermind.

[gt_addict]

That makes sense. Thanks Biodom. Its running my single green compac now so i am hoping once vh updates it (and hopefully provides lamens terms to update the current version ive got  ) then ill be ready to go for when my 2pacs get here 

[vh]

New build is available (b756f23).   git pull and build as time permits.

- Supports bitshopperde compacs.
- Can now combine --enable-icarus --enable-gekko
- Auto recover attempts from usb write error.

Latest windows binary:
http://23.108.83.14/images/cgminer-4.10.0-windows-gekko-b756f23.7z

[vh]

Here's how to grab the update:

Code:

cd ~/git/vthoang/cgminer/
git pull
make -j 2

./cgminer -o stratum+tcp://solo.ckpool.org:3333 -u 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr -p x --suggest-diff 32

Adjust that last line as needed.

Pull the latest code and have at it.

And if icarus driver could be tweaked not to accept Compacs and 2Pacs, that would be great

Nope.   

Use the -n flag and --dev flag in cgminer to select the device you want.

Use --enable-gekko to support the Compacs and 2Pacs.

Superb!! Thanks vh. I'll do the update after work.

Edit: just did the update as i had five minutes. Works a treat   

[MrZoidberg]

Hello, sorry for the noob questions.

1. What is the significance of the -p x flags?
2. When using ckpool, what is the benefit of specifying --suggest-diff 32

Thanks!

[sidehack]

-o is the pool, -u is the username, -p is the password. Most pools don't require a specific password but it's there just in case, so most people just use something generic like "x" or "123". Some pools use the password field to pass in additional parameters for multi-coin or leasing rigs and whatnot.

Since most pools expect you to run a multi-terahash miner but these guys are, at best, about 40GH, the initial diff threshold the pool gives will be ridiculously too high - a lot of them now start at 4000 or so. --suggest-diff tells the pool to start at a lower number so it can more quickly and accurately gauge the actual mining speed of your sticks.

[MrZoidberg]

Awesome, thanks! So if I'm using a 2PAC, --suggest-diff 32 would be appropriate?

Also, on ckpool, they quote the numbers "shares", "bestshare" and "bestever". What is the significance of these?

Thanks again.

[sidehack]

Shares are what you're sending to the pool. It's the result of the hashing calculation. The diff you get from the pool is a share value threshold below which cgminer doesn't bother to send that share to the pool. This keeps down traffic, since if a pool accepted every value-1 share bandwidth requirements would be through the roof with modern high-hashrate miners. Your returned shares could have a value in the millions or billions; this is statistically unlikely but it does happen on occasion. The more hashrate you have, the more likely you are to return higher shares, so the higher the pool's discard threshold gets. Every share is weighted by that threshold and summed up (that's the "A" field in cgminer's display, means Accepted), and that's what is used to determine your mining payout because it's a representation of how much work you're doing. Shares are all weighted by that diff value but every individual share could have a different value (which is reported in cgminer when a share is accepted). The only share that actually matters is the one over network difficulty, which is the one that makes a block. The rest are just used to divvy up the block payout to everyone in the pool.

So "shares" is the total number of shares you've submitted, "bestshare" would be the highest-value share you submitted in the current round (?) and bestever would be the highest-value share ever submitted under your mining account. They're not really used for any payout calculations or anything (except total shares, indirectly), but some people like to know that info.

[lanegg]

This seemed too easy and I am doubting myself. Are these hash rates correct?

https://i.imgur.com/ocRhwRl.png

I know I've overclocked the sticks to 250mhz so technically no longer supported, but I thought the max was 15gh/s? Or is that just the CYA max?

Also, how do I check what the vcore is as referenced in the graphs in vh's OP here? I have seen references and pictures of the potentiometer but I haven't seen a ELI5 on how it works, which apparently I need...

Yes it's correct, but it's about 10% off due to the amount of HW errors the chips are throwing out. 
I deleted the word max in my example, its meaning was in reference to the highest you'll see for that specific frequency.

[vh]

In case you aren't, keep some air flowing across them to keep the chips from overheating at that frequency.

If you intend to stay at 250MHz, you can turn the potentiometer lightly clockwise until the HW error on that stick stop increasing.  

Otherwise, for best results, lower the frequency until all four shows HW:0; until you have a way to measure core voltage or overall amperage.    

[sidehack]

Look at your WU number for a practical reference of how much work is being done. I believe the hashrate is calculated statistically off the rate of share returns, but the WU (work units) is a reflection of the actual data being processed. For 100MHz you should see about 150, so 250MHz is 2.5 times that at around 380. If everything's working as expected, your HW will be zero and WU will be a lot higher.

Hashrate (GH) is calculated as 0.11 times frequency (MHz), so 100MHz gets 11GH and 250 should see 27.5GH. At that frequency, you need a core voltage about 700mV (1.4V device-level). The stock voltage is about 620mV, good for 150MHz or so. The stock voltage setting, your wiper (the point opposite the flat) is in about 7o'clock position; try turning it to 12o'clock. That should get you close. But as stated, you will definitely need a fan for cooling because the sticks will be drawing about 10W by the time you get them leveled out.

[vh]

When I added in the ticket mask support, the Work Units stop scaling linearly.  

Reduce the WU calculation by a factor of (ticket mask + 1).
250MHz = ticket mask of 3 = WU: 95/m. -edit: fixed

Everything still applies otherwise.

[lanegg]

If you intend to stay at 250MHz, you can turn the potentiometer lightly clockwise until the HW error on that stick stop increasing.

That fixed the HW errors. They are now 0 after running for about 10 minutes. I also backed the throttle down to 225MHz. I have a little USB fan cooling the devices but right after I posted my first reply I got a seg fault that crashed Raspbian and had to hard reboot it ('reboot' command wouldn't actually reboot it, it would just hang). I am not sure if they are related but since I had the devices hashing all night @ 100MHz without issue it seems too coincidental to not be the cause. I'll keep an eye on it for sure.

try turning it to 12o'clock.

I definitely don't have 20 year old eyes anymore but it looks like the dial on the pot has two flat sides. Are you saying I should turn it nearly half way? Clock or counter clock-wise? Is there a way to check what the actual wattage being pulled is (like in the USB management)? I didn't see it on a cursory glance but maybe its something that can be calculated?

Thanks for the support guys!
