GekkoScience Compac BM1384 Stickminer Official Support Thread

As mentioned if you've tried zadiag AND used the option to show all devices and it's still not there odds are that you've got an issue with your machine.

Reboot, try another USB port, etc

Before doing anything when you first plug it in, windows should notify you that its installing drivers for a new device.  Let it complete before running zadiag.

You can always check your windows hardware list to see if it shows up anywhere under the USB section too.

HI, I'm thinking to buy this hub (to Belgium)

What do you think?

Should give 900ma/port

in case you guys are wondering, .9A is 225M @ .7v

Just got mine in the post, thanks Sidehack!

Just in case anyone else gets this issue..

I wanted to try my sticks in Windows before I set up my Pi at a later date. I installed Zadig and the special cgminer (in 1st post of this thread) but I had to install a zlib1.dll into system32 before cgminer would run. Secondly I was getting error "libusb_sucess" in the cgminer, I had to go to (Win10) control panel>hardware and sound>power options>change plan settings>change advanced power settings>usb settings>usb selective suspend setting>disabled.

Try removing and reinstalling the stick with cgminer running.  I know with Windows 10 mine get stubborn and sometimes this helps.

[sidehack]

Yeah, there's not even implied support for these sticks on Windows 10, because to test it I'd have to have an internet-connected Windows 10 machine and that's something I have zero interest in setting up. I'm sure that alienates some of the customer base, but to be honest I don't really care.

Also, if you're getting that reset error and it's not submitting shares and the white light isn't flashing, something is pobably wrong. Check the voltages to make sure everything's peachy. If the 0.9V is reading more like 1.0V something's wrong. If VCore is reading outside the range of 0.55-0.80V something's wrong. If Reset is reading outside 1.5-1.8V something's wrong.

If something's wrong, contact me for warranty info. But if you contact me for warranty info, I want to know everything you've checked so far. I want to know if the heatsink gets hot while it's running, I want to know what the frequency and voltage settings you've used are, I want to know if you're using cgminer stock or cgminer-gekko or BFG, I want to know what the voltage measurements are, and I want to know how cgminer and the stick's LED behave when it's plugged in and when cgminer tries to initialize and when it tries to mine.

[chiguireitor]

Have 4 of them running on windows 10 machines. No prob there.

[zOU]

I finally received my heat sink !



Now I just have to drill/thread both of them.

I wanted to use thermal pads but the chip is not large enough and the heatsink slides off...

[Legacy2005]

nice size heat sink. what volt/freq are you running them at to need such a heatsink?


Wonder how the heat dissipation will be for the middle one. are they lotto machines or part of a pool?

I run 6@300Mhs, maybe 310.

I don,t remember vcore I prob posted it a few pages ago :p

They're part of a pool

I built a tunnel like cooling system/holder, so this heatsink has the fins oriented correctly

[cavaliersrus]

yea the heat on them will be greatly reducted with a correct heat sink and the tunneling idea

[zOU]

yes, I noticed that on some of them, the pcb under the chip was darker.... looks like they were hot enough...

And when I removed the stock heatcink, the screws were pretty easy to removed.

As I still need to dril/thread the new heatsink, I cleaned the chip, applied fresh thermal paste and secured the green heatsink back in place

[cavaliersrus]

have you thought about useing a blower type fan like a laptop uses



or something along these lines then you woulddnt need a push pull config and you would get better air flow across the heat sink if you put a something over the top of the heatsink like another piece of metal and directed the air just right into the fins of the sink ?

There's not enough space between the fins to make that good enough.

This is an old picture I posted.
it's a lot better in fact (front/back walls + airduct directing the airflow down on the heatsink)

Seems working for me...  No Block yet.

If I have to buy a few multimeters and solder them directly I will!

I'm more curious about the difficulty setting of 19.  What's up with that?  I use a value 1000 with my two (total of 600 WU/min).

ckpool's auto adjusts the difficulty depending on your equipment mining speed / number of shares so in this case its adjusted to 19 diff.

You can set a suggested starting diff in cgminer by using --suggest-diff 30 which is what I use for my stick. This doesn't work on all pools though.

Here are a couple of runs on 2 different Compacs - both were modded but the heatsinks are stock- - A fan is all that is needed, they are built like tanks
