GekkoScience Compac BM1384 Stickminer Official Support Thread

[zOU]

for BFGminer:

--set compac:clock=*** (decimal, not hex)

you can fine tune them by:
- setting them at the frequency you want to achieve (assuming your hub port can deliver the W)
- setting core V until you get no HW error using the "screw pod"

I know it's a PITA but this has been discussed at length in this topic, tru a search, or reading the last 10/12 pages (that's when I arrived and asked and summarized a lot of things )

when to issue this ^^^ command? Does it mean that 250=250Mhz? At the same time when you ask it to mine (after the password in a string) or beforehand (in bfgminer directory)?
I use the command from TingaWinga5 youtube video (great stuff-described how all dependencies have to be downloaded) to run bfgminer:

Code:

screen -S Mining ./bfgminer -o stratum+tcp://POOL.com:PORT -u USER -p PASSWORD

if you have a better run command- let me know, please.

Code:

screen -S Mining ./bfgminer -o stratum+tcp://POOL.com:PORT -u USER -p PASSWORD --set compac:clock=*** (decimal, not hex)

thanks, this is helpful

my pleasure

you can add there any other option you wish to use

Hi! Just picked up 5 sticks, excited to hook em up!

I ordered this USB hub ( http://www.amazon.com/gp/product/B00OJ79UK6/ref=s9_hps_bw_g147_i1 )

Just wanted to confirm it will power up all my sticks correctly, as well as power a rasp Pi 2 and 2 arctic breeze fans...

Thanks for the help!

From what I can read, its only a charging station.. get that and 5 Y power splitter cables and a 7 port/5 port USB hub..

exactly...at least 3 different usb hubs were discussed in the last 10 pages here.

It is only charging so good thing amazon has good return policy.  If at all possible if you just placed order try to talk to customer service and see if they can cancel it out before it ships.  If it just takes longer and shipping back.

But make sure in future to get a hub, not just charger.  A lot of these chargers have really great power... it's since they are meant to charge fast.  But if they have no data cable to go to computer... all you are left with is a charging station.

Would be good if Gekko can come up with a nice big unit like bitmain and take the improvements used to tweak the voltage. Would love to see a unit come out in the future that has such options available. Is their any plans on bringing out some 4TH units or above in the future?

If you plan to use Y-cable you can use it as the power source. Then you need a real (maybe powered) USB-Hub for data.

Order was cancelled in time, thanks for the help its much appreciated....

So what's the general consensus for a hub to both power and transmit data for 5 compaq's?

This one works good

http://www.amazon.com/Superbpag-Portable-Charger-Transfer-Samsung/dp/B013OK10YM

It even work's with Raspberry Pi 2-B (Pi's are very picky on hubs and will usually never work with usb 3.0 hubs or even some 2.0 hubs).

It will do ~2 amps per port, I've ran 5 sticks at 250MHz for over 2 week's with only about 3 HW errors (once you get the pot on the stick adjusted).

To large... I highly doubt gekko wants to compete directly with bitmain's S7 type products as bitmain makes chips.


I am hoping they continue on with the pod miner, something like the "new rbox".  




Having power issues as well with my USB hub but it's crap lol any load and the voltage starts dipping.. Don't use a hub that has a 12VDC power supply lol.

Will a rasp2 be able to handle 3 miners connected to it's USB ports if it is powered via a hefty PS? 
Overclocked to liek 250Mhz is what I would want to do.

[zOU]

I'm pretty sure the RPI has a strict USB management and won't allow more than 500mA/port.

plus 3 sticks won't fit unless you use a cable extension.

I have 5 with Y cables on a orico A3H10, running 240Mhz.

I've not tried more yet as I'm waiting for the USB doctors to arrive to fine tune my sticks.

PS is 36W, so 7.2W/stick with should be able to get them over 325Mhs.

also 1 USB3 port is 4.5W so using Y cable i could get 9W/stick, but the 36W power supply is the limit in my case.

I have one stick running on a Raspberry Pi 2.
I have not changed the voltage-setting yet, and it is running at 150MHz. I have no idea of how much current runs through the USB-port.

I have changed the powersetting on the RPI:

Interesting re 5 sticks on Superbpag (BTW, I second the Jake36 and zOU opinion)-I failed to run four, but maybe because I hot-plugged them without reset.
Three are good with almost no error for a couple of days.

BTW, how did you fit five sticks there? When I tried to put two sticks in adjacent slots they touched. I was not sure if this is OK or not.

Superbpag is 70W/14A (7X2A slots). I also just got an incredible 3A Y-cable from Cali. The thickness of it...the only caveat is the f-f coupler (to link Y and stick), which is less formidable, otherwise, I am ready to try for overclocking when i have a bit more time.

What is highest cpu the new gekko can run with and still be stable?
Is any difference on using cgminer or bfgminer for best performance stability?

You mean highest Mhs ?

Depends on voltage and cooling.

Search this thread for overclock, some ppl have achieved pretty amazing speeds.

[christiansenn]

Yeah.

Is it better use the Gekko cgminer one or bfgminer?

from those example:
GekkoScience cgminer:
To build use --enable-gekko flag.

./cgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr --compac-freq 250
---------------------------------------------------------------------------------------------------------------

bfgminer:

./bfgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -O 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr --set compac:clock=x0b83
---------------------------------------------------------------------------------------------------------------

[zOU]

I'm pretty sure that bfgminer suport decimal freq, not hex.
