whats the minimum amps for the minion boards to get them to run

Could try this with 4 minions enabled:

1 HEX4M:

400 MHz
660 mV

170 GH/s
170 W
12V, 14.5A

Cheers will try. But. He's getting no leds at all

[technobitVesi]

check this
disconect everything.
1.Conect 12V PCI-e
2start the PSU (PSU fan running)
it should blink the red led near the MCU(pic)
3. Connect USB to PC or TP link after 2-3 sec it should light the green near MCU ( indicates USB is present)

[sorehammer]

he's getting fans spinning but no leds at all he's tried 2 boards and 2 psu's

[technobitVesi]

HI,
clearly there is no USB connection.
If they tried 2 boards for sure have to check USB ->hub->tp-link or PC

[me2014]

tried on two comp,with two usb cables...but without hub,as it is in tutorial,boards can connect directly to pc without tp link or hubs...and when I try that pc doesnt recognize usb at all :S the only possible thing is that the boards are not wotking..am I right?

[technobitVesi]

No
You just need drivers under windows.
Zdiag
and then cgminer compiled for windows
Give us teamViewer and We'll help

[sorehammer]

you can't install drivers if the boards are not seen by windows though

[me2014]

zdiag cant recognized it..it looks like i didnt plugged it at all..:/ can u check it in a two hours via teamw,when I come home?


whats minimal requirements for psu?wats and amps?

Update: Since yesterday my miners have a performance increase of about 200 to 300 GHs. Thanks.

Hi all,

When placing coolers on a HEX4M chips anything special to mind to? Or is it just the same as placing cooler on CPU?
Asking because in few days a new hex4m without coolers will arrive.

I've got standard cooling paste here, do i need special cooling paste, e.g. with extra silver in it, or can i use cooling pads instead of cooling paste?

Sorry to ask, but have these been tested on p2pool? I quite fancy a couple if they work OK.......

HI,
We are working on a P2Pool solution for our miners.
Will update as soon as tested and ready

Regards: Vesi

That's great news, thanks. Look forward to seeing the results 

Any news on this?

Depends on the quality of your cooler blocks.

Some cheaper blocks (like mine) are not perfectly flat, giving rise to hotsposts on the die. this manifests as good hashing that goes bad after a little heat buildup, in this case you have two options:

[1] lap your cooler blocks to get them flat and use a good paste. best option but alot of work if you have many boards.

[2] use slim thermal pads with best conductivity you can get. this works better than paste because it has a little elasticity to it and always expands to fill voids.

regardless you should go for best thermal conduction you can get, for paste I use shin-etsu. for pads i use a thin thermal adhesive pad, the type used for sticking sinks on RAM etc (smeared with shin-etsu)

Hi,
Yes , but not ready yet.
For sure you'll need a host PC or beagle bone with wallet client software.
Soon we'll be able to provide working solution on this

Ok, thx. i'll use pads then i've already got good quality right here.
I've got the artic coolers for the hex4M, they where delivered with the board

[technobitVesi]

Hi,
just remove the whole set and mount it on your new board.

Regards : Vesi

[retrogeek]

I received my HEX4M (thanks Technobit!) installed coolers and was hashing happily away for 2 days ...

And then disaster struck!

My cheapo power supply melted its PCIE cables and burnt out - I should have known not to use 2 connectors from the one cable - but it was all I had 

This has left me with a damaged HEX4M board - I can connect to it via USB, but it hashes at 3-5Ghs for a few minutes and then gets dropped by cgminer.

So - I need some hardware repair!  I'm in Australia, so shipping all the way to EU back to Technobit is likely to be expensive and will take a while.  And it's been quite a long time since I've picked up a soldering iron - the surface mount stuff would be beyond me anyway ...

Any suggestions for local repair?

Failing that, Vesi/Marto: How would I organize return to you for repair (at my cost of course)?

[WiWi]

Hi Vesi,
ok, thx. i'll work it out. Have already placed many coolers on cpu's was just wondering if there where any special things to think about in case of an hex4m

When i look at tracking & tracing of dpd, it will arrive tommorow

edit: 14-10-2014, it has arrived. today i'll swap the coolers.

Lot of errors, what could be the source of this?  Vesi, are you Guys able to look into it with teamviewer? I cant find anything wrong.

mm, board goes zombie after 15 mins, hashrate at about 50 GH/s

what is the problem here?

with setting at 960 instead of 1024, it does about 200 GH/s, but still no stable hashrate

Going to try to use version 0_4_0

[technobitVesi]

Hi,
For sure the board was tested.
you have to check coolers attachment.
use the whole set you had on your previous board.
Give me TW access or contact Martin on skype
