GekkoScience Compac BM1384 Stickminer Official Support Thread

[vapourminer]

I have an existing Minera setup which works well so I thought I would try the cgminer-gekko image posted in this thread.

However whenever I plugin the USB Miner I get the following:

Which is great but it's followed by:

I've also updated the firmware of the PI, updated all of the software packages and updated minera to v0.7.0

Anyone else have the same setup and had this problem?

Regards Gareth

i never got minera on the rpi b to work with my compacs.. probably user error and i didnt mess with it  to be honest.  i just disabled minera and compiled straight from the source for the gekko version of cgminer.

upshot is I just didnt use minera, i compiled the gekko version of cgminer on the pi and ran it from a terminal.

btw the 4 compacs on the rpi have run several months non stop perfectly. they (pi/hub/compacs/switch/modem/router) are all on ups, so that helps too; crappy power here.

the 5th, compiled on ubuntu 15.10 runs fine for weeks at a stretch but that rig is not on a ups so it drops dead when power glitches otherwise im sure it would run non stop also.

vapourminer, or any other pi-heads out there, I searched the forum here and elsewhere and can't find an answer.

On my either 2B or 3b (I'm pretty sure 3B) I run two copies of cgminer concurrently - one runs 4 sticks at 425, and the other runs three sticks at about 350 or 375, whatever I can get them cranked to.

POWER for the pi comes from an unpowered (port on-off switchable) hub connected to a powered 2.0 hub, as does the on board pi port go to the powered 2.0 hub.  THe 2.0 uplinks to 2xSuperbpag 3.0 running sticks in alternate slots, staggered for maximum airflow, with four fans going on.  Two fans are run from the *2.0* hub, and the other two from the secondary 3.0 hub (where the three slower sticks sit).

Here's the issue:

If I run both simultaneously, I can almost always count on loss of network connectivity within 24 hours.  I can restore it by unplugging and replugging the network cable, and there's some talk of ifup/ifdown commands to refresh the DHCP lease, or setting the IP static.  I Also added eligius to the hosts file to see if that helped, but it didn't.  I lose the ability to talk to eligius and im down until I notice it.

HOWEVER - if I just run the 4 sticks at 425 its rock solid for days. (the other three are plugged into their superbpag but the hardware refresh is 0'd out or they are zombied on my active cgminer)

Any ideas?

Thanks,

drupie

very cool and interesting idea there

[Mikestang]

I like the little fan mount, cool idea.  You could probably even get 2 of them on there and then cover the entire heat sink.  Do you have a laser thermometer?  Would be interesting to see what the temp difference is on the heat sink beneath the fan and on the sides.

[drew_ii]

Thoughts about soldering the power leads direct to the +5v/Grnd leads of the USB connector instead of running it off of another port through another cable?

[gt_addict]

Someone has already soldered a barrel plug to the 5v and gnd for additional power delivery. Its further back in this thread I think, or try the gecko run thread on the main page.

Yes, I do have one of those.

temperatures:
Room:                   30 degr C
Heatsink side:        40 degr C
Fan top:                 41 degr C
Heatsink under fan: 61 degr C

Room temperature is pretty high because of outside temperature being 34 degr C here today.

Isn't this the cutest littlest fan! I just found 4cm fans for my sticks and they looked completely out of place

[aarons6]

if you guys have a string of these in a hub, maybe 4 or 5 this might work

i personally just use a big honeywell fan..

on its lowest setting its near silent.

Welp one just died.  Wont even init.  Solid green, no init pulse, wont run at 150, just sits at 0.  I think I killed the chip.  RIP little bugger.  Waiting on MM Test Leads to ensure core voltage etc.

[TouchFluffyTail]

I have 3 sticks sitting in a Rosewill hub that also powers the rPI that controls them and Arctic usb fan.
I've noticed yesterday that one stick flashes slightly pink when it's hashing, it still has a solid green LED on. the other 2 flash normal white.
I'm still getting a stable 32~36 Gh/s.

Is that normal, or is it indicating that the stick is about to die?

[sidehack]

The flashing circuit is completely independent of the hashing and controls parts. More likely it's an issue with the LED or an attached resistor.

Thanks, I will just leave it alone and try not to get bothered by it.

Greetings.

I've been attempting to get my Compac working for the past week.  All attempts in using gekko-cgminer (including but not limited to reinstalling various drivers and a fresh install of my OS) have invariably ended in the following error:

The application was unable to start correctly (0xc000007b). Click OK to close the application.

Attempts to use bfgminer have met with a small degree of success, but I am unable to find the device.

Since I am using Windows 10, I have used zadig to install the proper driver, but I am now at a loss as to what to do next.

Any advice would be greatly appreciated, and thank you in advance.

I'm assuming you've looked into the thread enough to know there's a DLL missing from the Windows build that needs to be copied across from a stock cgminer archive?

Gadzooks!  Foiled by my own poor eyesight!

A quick search solved my dilemma, and all is now well.  As thanks for your quick reply, I'll donate the first few days of mining to the listed sandwich address, unless there's another one you prefer.
