GekkoScience Compac BM1384 Stickminer Official Support Thread

[vapourminer]

Hello guys,

what hubs would you recommand for these sticks please?
Read those orico's are good bur which ones? Pictures are very much appreciated.
I'm EU based (Belgium)
Making my own PC case with cooling & hubs
I'm so curious about my order!! Always loved to create my own computers!

Just to be sure, I can run these just out of the motherboard usb posts also he ?
And you don't need strong h/w also he? I'll have a dualcore atom NM10 2 GB DDR3 @win7-64

you will like your order.

in the USA get a suberbpag 70 watt hub but you cannot(?) in the EU as no CE rating. someone else will chime in on this, sorry

my bone stock intel mobo in a HTPC with USB 2.0 ports ran two compacs with stock convection cooling. great if you like absolutely silent hardware.

Interesting - I got two new batch 2s (for three total) and one of them constantly resets and eventually stops doing any work.  Right now its ID # is 784

so I have

   0: COMPAC 10002125: 300MHz                  | 18.01G / 16.60Gh/s WU:231.7/m
   1: COMPAC 10000268: 300MHz                  | 19.06G / 16.59Gh/s WU:231.6/m
 784: COMPAC 10002121: 300MHz                  | OFF

As you can see I've disabled it for now.

I have the voltage set the same on all three and they're all running at 300mhz.

I need to do some testing and see if the problem is the hub ports or the stickminer itself.

I'll report back once I figure it out.

The same compac above (10002121) continually gets "no valid hashes for 10 secs" and then resets - and just continues that cycle.  I haven't figured out why yet.  I need to get it on a different machine to drop everything to stock settings and see what happens.  It may be that this one just doesn't like 300MHz +  (which would be odd)

Just a simple check to find out if it's hub power, pull one of the hashing ones and see if #2121 starts hashing.

If it does, you know it's the hub's power.

Does it initialize but the white light never once flashes? If so, it's a bad connection between the ASIC and PCB.

funny you should say that.

I had 13 working for months and months.

 I decided to tighten the heat sink screws on all 13 of them .

Every screw got a bit loose so I was happy I decided to do this.


I now have 12 working I think I overtightened the heatsink on that one stick.

That stick now does exactly what you say  above.

[sidehack]

I had one yesterday that was giving me fits during final testing. It worked on my bench, but failed to submit shares after fully assembled and put on the test rig. So I took it back to my bench, popped the heatsink off and it lit right up. So I tried reflowing that pad with my iron and twice more it did the same thing - disconnected as soon as the top screw of the heatsink was tightened down. For reference, the output pin is on the top edge of the ASIC.

I will test with a fan and no heat sink

I'll have to try that on my 1 that does that also.

mine is dead.

so who wants a dead stick?

 free usa only  i will spring for postage

and to others after looking closing at what i did I can see if you over tighten the bottom two screws with out keeping the top single screw equally tight.  it puts pressure on the bottom of the chip.

most likely I cracked a solder on the top of the chip.  with my double cataract surgery repaired eyes small close up work is hard for me.

I never was an ace  at solder now I am more like a three or a four.

Send a pm with a mailing address first one in gets it.

usa only.

before you give it away, if you have a heat gun or a good hair drier you can try to heat the chip up and see if it will reset.

Or you could look into getting it repaired by the manufacturer. Damage by the customer isn't covered under warranty but I hear the repair rates are pretty reasonable.

thanks for the offer.  but you have a lot to do. 



cavaliersrus   was first.

so I will send it to him on monday

aarons6 was second.  next one I kill i will send to you.

[sidehack]

Well, looks like I'll be hearing from cavalier about getting it fixed then, on account of he lives just up the road a ways.

or you can use a fan and a small heatsink with a thermal pad...

yeah  I  noticed address was in the same state. LOL

[cavaliersrus]

lol i coulddnt help but pull the trigger once i herd that from phil

and yea side hack ill bring it over

ill have to adjust the power across all the sticks that way i dont burn up the powersupply the hub is on

[vapourminer]

this is why we buy from sidehack

*cough* certain manufactures *cough* do not allow people to just stop by

[cavaliersrus]

yep i dont just stop by his shop i always ask him when a good time for him would be

Does it initialize but the white light never once flashes? If so, it's a bad connection between the ASIC and PCB.

It's funny because for a short while it hashed out of the box.  Then I started running into this.  But yes at the moment it does initialize (light up) but then never a single flash.

I need to do further testing - I got the same error no matter which port on the hub I used, nor a usb port on the server.

More testing to come.  I'm going to knock the voltage and frequency way back and see if things play nicer.

Second stick from this batch is acting up now.  

 [2016-02-21 13:09:16.037] COMPAC 2: No valid hashes for over 10 secs, attempting to reset
 [2016-02-21 13:09:16.217] COMPAC 2 attempted reset got err:(0) LIBUSB_SUCCESS

BUT - again i haven't had the time to rule out the superpbag so I'm not making any conclusions.  I just need time to test.

i have this hub.. and i have this error.. what i did was unplug the hub and turn it off.. then turn the hub on and plug it in..

some reason the hub doesnt like to be turned on after you plug it in.


edit.. i think its the hub

i just got it yesterday so i didnt test it very much and i am today and im getting this

they switch off, one by one until none is running.
