Start cgminer without the sticks
Plug 1 stick
See what happens
Plug the 2nd
See what happens

Are you using a Powered hub ?
What is vcore set to ?

Can plug in 1 stick (root USB port on Windows 7 workstation) (SN ending 777) and it picks up and hashes fine (8-10GHash/s).  I test the other stick (SN ending 767 I think) and most of the time, nothing.  Both LEDs stay solid.  Once it seemed to initialize and flickered for maybe 3-5 seconds?  Just enough for cgminer to register a few 100 MHash/s... then it stopped again.

I pulled a meter out and probed VCORE on the back of the PCB... and both registered about 620mV?  The pots haven't been touched on either.

No powered hub on the bench at my workstation.  They *were* in service on a powered 10-port hub from bitcoinware.com powered via a regulated 12V DC supply, and hashing via a Raspbian RPi.  Again, this is not what I'm testing them against now... but where they had been running for the past 3-4 weeks.

Thanks for the reply.  Cheers!

600mv would be the minimum.. id plug that one in, and slowly turn up the volts until it starts up.. they make a special plastic screw driver to do it..

you can prob pick up at harbor freight tools if you live in us. or any hobby shop.


if you cant find one, then id unplug it each time and turn the pot..

They can be adjusted hot with a metal screwdriver. Happens at least once to every single one of 'em before they go out.

good to know, i figured touching it might short it out or something.

i can vouch for that, nothing bad can happen, unless you slip the driver off and knock a component off.. the pot cap basically covers the resistive material under it. unless you are rough with a driver and attempt to move it in other ways other then where it wants to go, I think you can be clear to even use a finger and some pressure..

Alright, what's the top end for VCore - What should I not go above? What if it doesn't pick back up?  Any other ideas?

[cavaliersrus]

the vcore it depends on what speed your running them at but i know they are good for max range on the pot i think the top is .8 or something like that

but if your running them that hot you better be running some cooling on them

I just want them to run, period.  Even at 150 or 200MHz.

Hi,

Do these need USB2.0 or USB 3.0?

Do they work with multminer?

cheers

Well here is another heat sink idea. Kind of like this one compared to the monster but this one gets real hot at 400 so I had to back it down pretty good.

[Vociferous]

Is it compatible with Raspberyy Pi? I saw a Bitfury red fury being used with one, hence me asking.

Thanks.

[vapourminer]

yes.

As said above yes it does.  There is install instructions on page 3 that I believe work with RPI (been a while since I had to set mine up).

If you get a good hub it can be a very good miner and a great combination with RPI running them.

Nice,

My large heatsink are on their way to me from China

Will post pics once I finalised the setup

Hello guys,

what hubs would you recommand for these sticks please?
Read those orico's are good bur which ones? Pictures are very much appreciated.
I'm EU based (Belgium)
Making my own PC case with cooling & hubs
I'm so curious about my order!! Always loved to create my own computers!

Just to be sure, I can run these just out of the motherboard usb posts also he ?
And you don't need strong h/w also he? I'll have a dualcore atom NM10 2 GB DDR3 @win7-64

Cheers!

Interesting - I got two new batch 2s (for three total) and one of them constantly resets and eventually stops doing any work.  Right now its ID # is 784

so I have

   0: COMPAC 10002125: 300MHz                  | 18.01G / 16.60Gh/s WU:231.7/m
   1: COMPAC 10000268: 300MHz                  | 19.06G / 16.59Gh/s WU:231.6/m
 784: COMPAC 10002121: 300MHz                  | OFF

As you can see I've disabled it for now.

I have the voltage set the same on all three and they're all running at 300mhz.

I need to do some testing and see if the problem is the hub ports or the stickminer itself.

I'll report back once I figure it out.

I'm mining with no fan now to save electricity and also planning on getting a more better hub.
