One of these:

you may have killed it.


try 1 stick at freq 100 directly to the pi


see if it runs.


4 sticks on that hub is a lot of juice.


can you read the brick specs.

1  stick will pull 10 watts at  freq 200


so if the brick reads 5v volts and 14 amps

 it should be okay,

but if the brick reads 5 amps and 12 volts   

some math 5 x 12 = 60  convert to 5v   means 60 x .85 =  51 watts   that is 12 to 5 volt


 so 4 sticks at freq  200  = 10 watts x 4 = 40 watts



so you have a 51 watts brick maybe ?  well    seems good    24/7/365 means derate by 80%  so 51 x 80% = 40.8 watts

so four sticks at freq 200  is pushing the brick hard  as 40.8 is close to 40

and freq 250 would be over use of power.

I believe you killed off the brick..

Those hubs are supposed to good for 14A and 70 watts. By your math I should be in the green, right? Is there a better alternative that others are using? I have seen people referencing other hubs but all the ones I have seen for sale seem really low on amperage for what the 2Pacs call for (they seem to be aimed at the first-gen eruptors).

I believe the hub  can do 70 watts  but not the brick ( many  have burnt this out)

look at the brick numbers  amps and volts.

I'm not sure what you mean by "brick". Do you mean like a laptop power brick? If so it doesn't come with one. All it has is a two prong wire that goes to the wall (or in my case a UPS outlet). The only specs I see on it are the same as what's in the Amazon specs. The unit has power since the 2Pac's green lights do light up.

I'm in agreement with the hub being toast, I am just trying to figure out if I got a defective one and should exchange it or look for an alternative. All the specs I have seen say this hub should well support what the 2Pac's require.

Direct plug no external brick correct?

Okay 4 sticks




5 volts 14 amps = 70 watts.  X 80 %  = 56 watts 24/7/365.

That 80%. Is due to 24/7/365 run time.

So if they are accurate it can do 56 watts 24/7/365.

4 sticks at 200 freq pull around 40watts

What freq did you run at?

Correct. Retail box contains just the hub, a USB cable, and a two prong wire for power.

the typical "brick" functionality is inside the hub/Superbpag.
there is no external "brick".
My 2c: don't run multiple sticks at above 200-250mhz. the table shows that 250 mhz is already exceeding superpag's 2A/slot.
before, i tried to run 5 Compacs on a superpag and when i overclocked, superbpag (box itself) was overheating.
If you want to overclock above 200, I would use Y-cables and only use 3 or less sticks/superbpag

Is there an alternative hub solution? All the ones I have seen can't support the amperage for the 2Pacs.

Yeah, and for $29.99, I am thinking that the components aren't meant for 24/7 draw to the max and even doubt it's scaled to 80% efficiency.  I have an Anker Hub rated at 60w, but the most amperage per port is .9 USB 3.0 standard.  I have 2 of them so I have backup as even with my Y-cables coming that will STILL only provide .9 +.5 (usb 2.0 power for second male), I am still a bit nervous pulling 1.4A x4 2Pacs, which MIGHT get me to 250MHz.  But that's the price you pay for science.  ;-)

The idea being to split the amp load over two ports?

Except (2) USB 2's will only net you 1.0 amps.  USB 2.0 = 500 mA.  USB 3.0 = 900 mA.

EDIT:  This will net you 1.4A: https://www.amazon.com/Black-Female-Extension-Mobile-CableCC/dp/B00ZUE6PVE/ref=sr_1_6?s=pc&ie=UTF8&qid=1491193047&sr=1-6&keywords=usb+3.0+y+cable

If you look at the specs (according to Amazon, so I guess a grain of salt) each port should actually support 2.4A/slot. That means (in theory) we should be able to go up to 275Mhz. Of course this assumes that the hubs can handle 100% load all the time...

In all honesty, to really get to where we all are talking about, you'd need to sacrifice an outlet for one of these: https://www.amazon.com/StarTech-com-Port-Industrial-USB-3-0/dp/B00V6ADRQC/ref=sr_1_2?s=electronics&ie=UTF8&qid=1491193356&sr=1-2&keywords=industrial%2Busb%2B3.0%2Bhub&th=1

2.4 amps per port is 80% de rate for 24/7/365

So that is 1.96 amps at 5 volts

Which means 1 port could do close to freq 200

There is the godlike beast monster hub that will do  19 sticks at freq 200 .

I will be doing a review on it .

Eyeboot on eBay.

But it is not cheap.

Look in hardware for the thread.

Yep, 2 left on Amazon as well.  Sexy 40A beast.  $245, but well worth it, if you have that many ASICS to power.

idea is correct, but i ordered mine on aliexpress as they had beasts with super-thick USB 3.0 cable when compac came about.
I think that I used Anker for it, but run it via Linux PC, which was so much easier to setup than Win.
the result was Compac (not 2pac) that was going at above 24Gh and I had to extensively cool it with a Vornado fan at 2in distance.
I don't have free Linux PC available at the moment. Might try and see if i can get something like this going with 2Pac.
