I'm sorry: I was meaning which version of the gekko are you using

[zOU]

3 compac on the DLink hub ?
with Y cables ?


this hub ?;


I've had issues with this one

I'm now using this one SuperbPag 7ports, with 6 compac @300Mhs

You may be over what the hub power can deliver.

I did a lot of attampt at running multiple compacs (I have 6 running)

I used several 10 ports USB2 hubs on RPI: worked more or less
I used a usb 3 hub for power and a usb 2 hub for data on a RPI: worked
I used a usb 3 hub for power and a usb 3 hub for data on a gibagyte Brix: worked
I'm currently using a USB 3 hub plugged in a USB 2 hub on a RPI: works

(i've since replaced the Y cables by normal cables for tidyness)

[raiding]

Wow. Your construction looks very awesome! Nice done!!!

Just for better understanding:

You plugged in your gekkos into the usb 3 hub you'd recommend me. All of your 6 without Y-cables (so you only need one of these usb 3 hubs). Then you plugged in the data-cable of the 3 hub into a random usb 2 hub and the 2 is connected into your pi 3. Am I right?

I've bought several hubs, too ... so I want to be 100% clear, you know

But I'm confused about your statement the d-link can't provide the power which is needed by the gekkos.
The hubs were also recommended to me by another user in this tread. He argued, that the hub has 2 charging-ports which can be used by the Y's to provide as much power as needed ... is there a reason in your opinion why your solution works and the d-link doesn't?
Or is the d-link just trash for mining?

[zOU]

correct

compac =>USB3 Superbpag => DLINK USB2 => RPI3

at 0.77Vcore, you stick should draw 7W, that's 21W (ish) for 3.

can you hub deliver 20W ?

I can of course be very very very wrong

[raiding]

I think you're right.

I tested the dlink with just one gekko. 200MHz unstable, 225MHz no response ..
So I think I need a 70W USB hub (unfortunately amazon isn't selling the Superpbag in my country. Hopefully I'll find it somewhere else in the www  )

Thank you all very much for your help!!

I was running the US AND EU versions on the dlink hub no problem.

[vapourminer]

my 5 compacs run on a rpi model b, stock rasbian image, with a superbpag 70 watt hub and an artic cooling usb fan on them. cgminer-gekko version, compiled from source.

i run root on the rpi and ssh into it. once in a while from cold boot all the compacs do not come up running, i just warm boot the rpi again and they usually come right up. never had to "hot plug" them.

compacs run at 300 mhz with 0.70 volts set on my mulimeter.. thats from recollection, might be wrong on that voltage though.

just listing what works for me. ymmv of course.

EDIT removed some unneeded stuff.

Plugable hub also works with pi and compac's:
https://www.amazon.com/Plugable-Charging-Adapter-Support-Android/dp/B00L2LK164

This is a BC 1.2 device, which means that it allows up to 1.5A per slot (limited by a total of 5A/60W).
I added Y's to it and was able to run compac's on it at a very high speed with heavy cooling, of course, just for kicks.
It does not matter that it is USB 2.0, hashing is unaffected.

[raiding]

Wow. Looks great! It's also avaiable in my country

How many gekkos are you able to run with one plugable? How much speed do you get (average) ? Does it run stable or does the pi "freeze" after a couple of days? Does it work without Y to?

At least three at high speed (18gh ea with arctic cooler cooling), more at lesser speed.
My recollection is that it was stable (we are talking about something that was done last winter/spring).
It works without Y's just as well. I use Y's only when I tried to do max possible hashing, which for me was 23.8HG/compac.

There is no downside to plugable, in my opinion. After you finish playing with compacs, you can use it as a high speed charger for iphone/android.

Is another production run of these Gekko Compacs planned?

[NotFuzzyWarm]

Is another production run of these Gekko Compacs planned?

using the chips from s5's: no.
AFAIK, no more chips available to harvest for them. Sidehack used all of the last s5's I sent him and I believe 2 from someone else to finish the last batch he made.

I should have bought a couple when I had the chance. Hope to see a Gen 2 version now

Gen-2 using a 14 or 16nm chip would be nice but not holding my breath there. Per Sidehack in a different thread, a full-up miner is on the plate for now.

That said, it's up to him to say ASCI-10 LF (Line Feed or in this case, end of line).
I mean if someone donates a sizeable stash of s5' to him, what the heck. Got everything for making them and if folks will pay enough for them to make it worth the effort, who knows?

edit: Hmm. Plus as a bonus, if the plans for a 16nm miner pan out, could use the donated s5 hulks for them. Make a deal with the donator for part of the sales, win-win. There has GOT to be a pile of them out there somewhere from commercial mines upgrading and all...

[sidehack]

CrazyGuy might have more available sometime. Yeah I'm really hoping to have a new version (new chip) sometime soon.

Maybe somebody did it, but I couldn't find any reply about it: Someone tried to use a big-ass heatsink with peltier cells? I want to know if we can set more than 500 Mhz per USB stick and how.

cooling is not everything..you could  just as well finish your usb connector while doing this "project".
also, isn't 800 mv the max anyway? 800 mv would not get you to 500mhz.

Hi MrKaizerSoze, that was me .

I´ve used a big hookup cooler and made also a couple of experiments with peltier modules..



Finally I pushed it up to 450MHz and it works stable!

(Higher is possible, (475MHz works !) but not long time stable.)

https://bitcointalk.org/index.php?topic=1173963.msg14928411#msg14928411

But therfore you have to modify the vcore pot (standard version is limited by 0.8V max), to increase the vcore up to 0.9V (900mV) and higher..

(see the value on the yellow voltmeter)








If any question, feel free to ask me...

holy crap what GH/s are you getting with 450 stable

[andymanone]

Hi cavaliersrus,
it works nearly @24GH/s.

I got an modified Antrouter R1 (comes from Bitmain, based on the same BM1384 asic) running @500MHz @27,66GH/s
