GekkoScience 2Pac/Compac BM1384 Stickminer Official Support Thread

[maticus85]

Did #xnsub (extranonce.subscribe) support get rolled into VH's latest build (Apr 30)?
I'm using it to connect to Nicehash but cgminer is giving me this:

cgminer.exe -o stratum+tcp://sha256.usa.nicehash.com:3334#xnsub -u 1xxxxxxxxxxxxxxxxxxxxxxxxxx
...
Failed to resolve (?wrong URL) sha256.usa.nicehash.com:3334#xsha256.usa.nicehash.com

I'm running a new 2Pac on Win10 64 on a powered hub. No other issues really. I can connect to other pools without the #xnsub tag just fine and I'm getting around 10gh/s at stock speeds

Using /#xnsub will let cgminer connect but Nicehash reports the worker as not being extranonce.subscribed.

Not sure if this is a cgminer issue, Nicehash issue, or a PEBKAC issue.

It will appear should it ever get added upstream.   Otherwise no.

Voltage issue.
I still am not able to get this thing to a voltage over 0.2v, not exactly sure what i did. Nothing has been broken off of the Stick, the only the i can think of is i could have hit another contact point on the board (see picture)
Is there any way i can get this fixed sidehack or like exchanged or anything for a fee? i got this thing from eyeboot, and when i received it the voltages were reading normal so its definitely something i have done to it.

If you got it from eyeboot, your first point of contact for service is eyeboot.

That goes for anyone who bought from a reseller. That person got your money so that person has an obligation to you as a customer. If the seller drops the ball I'll pick it up but the seller bears the responsibility of his own customer service so take full advantage of that. Honestly most of 'em are making a lot more profit than I am so they definitely owe it to their customers to have good customer service.

Compac != Compaq

Found issue should have looked closer for a bit longer....

[vh]

"compaq" 

The error sais unrecognised because it doesn't know what that is.

Yeah....I'm not proud of myself right now. Everything I see that I think of Compaq computers.

[sidehack]

People calling them "compaq" has been frustrating me for two years.

I live in Houston and Compaq is still in business here. albeit private stuff only, its the Dell warranty repair center contractor for this region as well if you know how to back track the return shipping label.

Retailers are dropping left and right around these parts.   Without a storefront most name-brands will be similar in about 5-10 years.

that's true, are you from around here?
In any case, I blame it on Amazon and Houstonstan's heat.
Blue apron delivers nice produce and recipes-close to restaurant's quality, so no need to eat out and Amazon with prime kills the rest of retailers slowly.

Yea, I'm by Rice for now but moving to Stink-a-Dena end of July.

Compaq was/is always never able to compete with SuperMicro in the industrial sector and just when they had a glimmer of relevance in the retail world they got shot down by Gateway. Always a Day late and a Dollar short of success.

I'm having some issues with a 2Pac, wondering if anyone has any ideas...

Was working fine; PC rebooted unexpectedly, and now I cannot get cgminer to recognize it. (have tried multiple PCs, fresh installs, etc.)
-Green light stays illuminated
-Windows recognizes device - shows in devices and printers
-when i run cgminer.exe -n, it finds device, and lists as GekkoScience 2PAC Bitcoin Miner
-when cgminer.exe is run either via batch or just launching the executable - always states 'No devices found'  (cgminer build is confirmed working with other 2Pacs)
-have verified and re-installed winUSB driver via zadig 2.3
-checked with mutimeter - pulling 0.02a, 5v, 0.217w

any ideas or assistance would be greatly appreciated.

Thanks,
CJ

Hi, just to clarify! You have 3 Sticks, 2 are working in the same Computer and with the same Cgminer (VH's) version, but 1 stick is not working? is that so?

[zumpbond2000]

Let me do a newbie question, please sorry if it's a too dumb question.

Would it be possible to change the firmware ( or something else ) of the 2Pac GekkoScience to mine with a different algorithm? Like Scrypt?

For firmware, not likely, the 2pac is an ASIC. Meaning its designed specifically for a single algorithm and this is hard coded into the hardware during manufacturing. They could release another version of the 2pac with different a algorithm but the one you already have will remain as is.

No. That is not how firmware works and there is nothing else you can change on the 2PAC to change its algorithm.

There were 2 devices running on this machine at one point, one of those devices is no longer being used.  The single stick that I have currently was running on this PC without issue prior.
