If you're going less big, this thread is full of hub reviews but you gotta do a bit of searching. I hear the name "Superbpag" come up a lot though. Phil's a good resource for hub info.

Sticks are still available from resellers. HolyBitcoin and ASICPuppy are about to get fresh stock, and if you're in Europe bitshopper.de should still have some of his.

I have this superbpag hub with 5 compacs @ 16.x gh/s

http://www.amazon.com/Superbpag-Portable-Charger-Transfer-Samsung/dp/B013OK10YM

phil can chime in with more  info

BTW i make no money off this Smiley

Even though Im not sure what these parts are, its pretty impressive that they list each component of the Superbpag hub.
I will have to see if I can get some more sticks, if so, I will probably be buying a hub as well!

[...blah blah..]
I have a good ups  that I have :

1 mac mini
my router
my ethernet switch
my linux pc
my 12 compac sticks

about 200 watts for all that.  I have had 2 quick outages (1 second or less)  that the ups saved.



yup

I have several UPSs along with a brigs 7000 watt key start generator along with a 7000 watt transfer switch (so my wife can run it).

we had a E3 tornado in town and 7 days (yes seven) with no power (these were separate incidences). look up "Monson Mass tornado" along with "Halloween 2011 snow storm northeast" (snowtober we call it). fun times indeed Smiley

..not a big thing, but i got my Gekko running @450MHz last weekend.

It´s already posted in Gekkorun-Thread, but maybe it´s of interest here too...

How it get it to work:
- Power brick 5V/10A supply directly on the Gekko PCB (see picture below)
- insert an diode in the 5V+ Line from PC-USB cable ( prevent a backflow from PS to PC, but be able to supply the Gekko also in idle or standard mode w/o ext. Power)..
- active Shark Copper/Aluminum-Pipe Cooler and passive backside cooler



Cgminer, running now at 450MHz


power measuring about 20 ~ 21 Watts



Cheers,
andY

Well it turns out that my gekko is having voltage issues. As soon as it starts the voltage drops to 4.3v even though I've got a Y splitter to the hub and a step down converter straight off a 550w psu breakout board. Has anyone got any suggestions? A decent hub that can be purchased in the UK that has enough oomph?

Ive got one of these:-     http://www.ebay.co.uk/itm/D-Link-USB-2-0-Powered-Hub-7-Port-Fast-for-Laptop-PC-MAC-480Mbits-DUB-H7-EU-Plug-/251975814197?hash=item3aaaedcc35:g:cUgAAOSwBahVZzLO

and one of these running off a psu breakout board:- http://www.ebay.co.uk/itm/DC-DC-Step-down-Converter-voltage-Regulator-24V-12V-to-5V-USB-Charger-Voltmeter-/221751716929?hash=item33a16eac41:g:q4AAAOSwqu9VN0ft

the gecko is connected to a USB Y splitter cable:- http://www.ebay.co.uk/itm/USB-2-0-A-Female-to-2-Dual-USB-Male-Hub-Power-Adapter-Y-Splitter-Cable-Cord-/272229841790?hash=item3f6229bb7e:g:Hv8AAOSwuAVWxN4G

The data end is connected to the hub and the power end is connected to the step down converter.

I get 4.93v until I plug the gekko in then it drops to 4.32v. It runs on 250m at the moment and wont go any higher and run stable.

What's the core voltage set to? To get higher than 250MHz needs to be at least 700mV. At that you should be drawing maybe 1.1A off 5V. Just guessing you've turned up the current limit on the 5V regulator?

Ive turned the vcore up so there are no HW errors. Seems to be running ok at the moment. Ive moved it onto the psu fan and the voltage has upped to 4.55v now. Its drawing 1.4a and around 6.4w.

The usb dc converter has no adjustment that ive found but was rated to 2a.

My mistake got the wrong listing. This is the one I have:-

But would this one be better?

Why not just get this and solder it to the wires of a Y cable power feed ?  

http://www.ebay.fr/itm/AC110-220V-TO-DC-5V-12V-24V-48V-Switch-Power-Supply-Driver-Adapter-For-LED-Strip-/361489672408?var=&hash=item542a76a8d8:m:mcsI3uSWMkf5ilLNvxKna0w

There's a 5V 60A model Smiley

It seems my 6 sticks are working a lot better on my RPI than on my gigabyte brix...

I had to connect the superbpag 7ports hub to a USB 2 hub, but I've had no HW errors at all in the past 2 days...

I have no idea about soldering electronics lol.  I can solder copper pipes together but circuits and components ive read are temperature sensitive and I could end up doing loads of damage.

next small success: first Testrun: Gekko@475MHz

Change:
- Increased the Vcore limit from 0.814 to 0.900V
- add a third passive aluminum cooler (backside of the Voltage regulator)

Some pics:

1. Vcore: (the yellow one in front, 900mV Smiley )

Wow 475MHz is insane!
Thanks for posting your pics this is a really interesting project.

I've got two running on stock power that are up to 190MHz.
Getting an average just below 20Gh/s on the two sticks. (Peaks to 25-27Gh/s but consistent 20Gh/s)
They havent had any hardware errors at 185MHz after about 24 hours. I'm going to see how close I can get to 200MHz with stock power/ cooling.
But I'm scared to push them any higher than that unless I have some additional fans and a powered USB hub.

Once I get these set to around 200 I might just let them run at Kanos solo pool and hope that I hit the jackpot.
(Not holding my breath but it would be amazing!)

Thanks for your feedback Wink

I think you should not risk that!
Maybe it works for a moment, but the Gekko will be definitely runnig to hot and the risk of damage after a while is very high.
If you take a closer look to my Gekko, you´ll see that I removed the stock cooler and used a very big Aluminium/Cooper Cooling Solution ontop,
a second Alu Cooler on the backside of the BM1384 and a third cooler for the voltage regulator,
all of them need also to be active air cooled!

Cheers,
andY

I've run sticks for extended periods (months) at 200MHz, but I have a cheap 120mm fan blowing across the hub. It doesn't take much to keep them cool at 200MHz.

Yes, of course it´s possible Smiley

Seems for me without a powerful hub and w/o an extra fan Wink

If he means stock power settings on the stick, they're all sent out with the voltage set to run 200MHz. Stock cooling is the only problem, but not much of one. 200MHz stable will only run about 4W.

Yes you´re right Smiley,
But one must note, that the standard USB 2.0 Port offers only about 500mA, thats insufficient by a 4 Watts usage.
So there is a need for minimum a 3.0 Port or a active hub...
