The Plugable 60W hub that has been suggested looks also interesting, however I doubt whether it will be sufficient to power the 5 overclocked miners 24/7.
That specific hub actually is maxed running just 3 sticks and you MUST make sure each is plugged in so it is 1 stick for each of the 3 regulators in it. Just will not have enough power any other way so more than 3 on it is out of the question.

I bet you could run 6x 2PAC if you set the voltage to the lowest value and only run them at 175MHz. You would only pull about 6.2W per compaq which should keep it well below each regulator's maximum and you would still get about 115.2GH/s overall.

Thank you for your reply. So it is not advisable to run 5 on them. I've also read your previous posts, it does indeed not look very good. Then my options are using two Plugable hubs or one more powerful one.

Thank you for your reply. Is this solution something that would work reliably 24/7, or can I expect a lot of interruptions? I'm fairly new to bitcoin mining. I've used in the past an Orico 10 port usb 2.0. But even with only one compaq attached I could not get the speed of that compaq above 12 GH/s. So that was quite disappointing. So now I'm looking for a setup that has been tested before and that is very stable.

And the House wins.
Care to play again?

Been there, tried that. Even with the sticks at OEM default of 100MHz it would not do it. Tweaking Vcore and speed, still no go with 3 sticks so forget about running more. For hubs NOT designed expressly for stick miners it seems that any power rating given is more of a suggestion than reality if you actually want 5v out @ rated power per-port.

My guess is that yes, a normal or a 'charging' hub *may* be able to provide rated wattage but it will NOT be with 5vdc coming out but instead the voltage will be lower. Maybe charging circuits don't care but the sticks do. The regulator in the sticks cuts off when incoming voltage goes below 4.4vdc. Even at the default 100MHz sticks were dropping out so....

That probably explains why I was only seeing 4.86v on each stick. How hard are you pushing your 2PACs? I was hoping to expand to 6x 2PAC, but since that seems impossible on this hub, I might as well push the ones I have a little harder.

1 USB miner running @ 200 MHz





Going to try with 16 x USB miners next...

Hi guys,

A little bit off-topic and probably silly question: do you think a laptop cooler would be okay to use as a solution for the 2Pacs?
I was thinking to sit the hub & sticks on this Deepcool N200 cooler, I'm assuming it would cool better than a normal USB fan.

so lay hub on its side        I think it is not ideal  as I think  the air moved by the cooler will not flow fast due to small grill.  I found one on ebay  for  22 usd

http://www.ebay.com/itm/Deepcool-N200-USB-Cooling-Stand-Pad-cooler-mat-For-Laptop-Notebook-10-15-6-/151877092837?



seems to me this would work better  and it is 18 usd

http://www.ebay.com/itm/Holmes-10-inch-Personal-Size-Box-Fan-HABF120W-/142100873644?

better yet this one is 9.99

I'm just brainstorming here, maybe we can come up with a more efficient, cheaper & better-looking cooling solution.
I can get my hands on the N200 cooling stand for approx. $8, same price as the Arctic but with (theoretical) better cooling performance.

The hub I will be using is the Plugable USB 2.0 7-Port Hub, so actually it won't sit on it's side.
The sticks - indeed - would be cooled on their side which concerns me from the efficiency point of view. What do you guys think?

Thanks.

Once a fan is used the orientation of the heatsink is a moot point unless it is one very tiny low-flow fan. Keeping fins vertical only matters with convection cooling.

I do hope you have read my earlier posts about the power layout of the Plugable 7-port hub...

I think that laptop idea will not work well

  in his case  :

                   

                __l___l__   >>  hub and sticks

               ------------- >> cooler

I think  the hub blocks air flow  to the sticks if he lays the hub on the fan and points sticks up wards

I did read it, and it helped. Thanks for the tips!

Almost, here is a simulation of what I have in mind.
At $8 I think I'll give it a shot and monitor the temps. If it works out then great, if not, I have 30 days to return the stand. Smiley



I'll keep you posted, my 3 x 2Pacs should arrive shortly.

For those trying to mine with 2Pac's and RPi's this 5V 4A hub from Amazon Basics is currently running two 2Pac's (not overclocked) through an RPi3.  Hub is USB 2.0 and is the only one I've had success with out of the 4 I own.  The ports on the front are higher current so it might even support a third stick but I only have 2 atm.

I have two and could part with one.  Bought them along with 100 block erupters years ago.  Mine are in good shape and have original boxes.

1) Hi Guys, I have a shit HUB, powered with 3A (at least in specifications), when I plug my Gekko directly in notebook port, I can mine at 200 mhz fine, but when I plug into that Hub, it even don´t start to Mine. Can I throw it away?

2) Another question, is it preferable a 3.0 USB hub or a 2.0 USB Hub?

Why would you throw away perfectly good hub? I would just use it for other stuff. You should get a USB 2.0 hub. The results from USB 3.0 hubs are sketchy at best.
