Alright, I have finished a process for making a heavy duty 2:1 PCIe adapter for Neptune owners. It is made with 16AWG wires and minifit HCS (high current system) pins capable of 13A. It is tricky to make with crimping two 16 gauge wires together but I soldered the pins to the wires after crimping for best contact. I cannot guarantee that the nylon housings at the pcb won't melt so be sure there is some airflow there.

Here she is:

Pricing is $8 each with discounts for larger orders. Shipping will be priority mail with tracking which is $6 for US and $24 for international.
Please PM if you are interested. Thanks

Another solution (but a lot more DIY work):

if anyone is interested, I have plates that replace the mounting apparatus they used. It will get the foam out of the way of the VRMs and allow more airflow over the PCB.

They'll come with the plates, screws, nuts and spacers for all 5 ASICs - .0675 BTC plus shipping (USPS Priority/Priority Express, your choice)

Sorry but they will not fit !.... you need an T-shape plate, and not an I-shape

How did you connect the pads between the pcbs?

I posted a lot more pictures here: https://bitcointalk.org/index.php?topic=313978.1133

does anyone push the mh at 500 mh or not?
hashing speed?

Yes, Elenelen posted this one page back : https://bitcointalksearch.org/topic/m.7564241

is better to put off the cover of the cubes? Huh

?

If you run them open you need to make other arrangements for lots of airflow.
The cube acts as an air tunnel.

YMMV

i put 3 coolermaster v1000
at neptune

but after a while the hashing speed is down
and each asic card from 298watt got to 218watt

any solutions for that? Huh

hashing speed at 2500 gh max

What temperature your VRMs?
Look on ADVANCED page.
Do not leave web browser on ADVANCED page for long time.
It causes slowdown of miner.

You may have die turn off because VRM is too HOT.

YMMV

still wondering if those vrms are holding out? now that we know they are the 40a model...and already over that plus high heat...wonder how long these babies will last?

They are decent quality, running them 20% out of spec as long as temps are kept within control shouldn't have any meaningful impact since the mining gear will be obsolete before their reduced lifespan starts becoming a factor.

However since it's KNC building these I fully expect them to forget the TIM for the VRMs on some units and them to accidentally use cheese for heat sinks on others, in other words if shit starts failing blame KNC and their shit QC and not the ericsson VRMs since they should be fine under controlled conditions Sad

So what do you think? Can I run 53Amp through them, if temps keep below 75C? {with a life-expectance of 10 months}

I'm currently running one box on 500 Mhz with 48Amp and below 70C. I like to try 550 Mhz and think that will pull about 52Amp. {with 550 Mhz on 5 boxes a 4 Ths miner could be possible}.

Will last just long enough to provide heat when the winter starts in november. And it's mining power is more than electricity

OK, I have a modified-DIY-box below 70 C and running on 500 Mhz:

How do I get above 500 Mhz ?

Contact KNC, maybe they'll tell you, or add an option in the next firmware.
Could you post pictures of your set-up ?

Edit : Would these 20mm spacers work ? How many do you need per box ?

if they have open holes in the corners of the board, I do believe they'll work - though you most likely have to take the "box" off to fasten from the other side of the PCB.

they do...and you wouldn't even need a screw holding them in...just screw them in from the bottom...i did on my boards and works fine

course one in the middle wouldn't hurt too for support cause the heatsink is heavy and don't wanna warp the board

what size thread M5, M6?

It's M3, and you need 5
