I asked Anna to explain what does "For Neptune Batch 1 and 2 customers, All refunds will be refunded in dollars and you can refund up to shipment" mean.

and she replied:

"This is not reconsiderable"

Who can explain such Knclish to me? Sad

i would presume that means, until the rig is boxed and shipping arranged via a courier, you should be able to refund.

Elenelen, when you get a chance could you please read the numbers on the two black 8 pin packages near the side of the board and post them here ?


There is no way to read anything on those VRM-boards: completely covered with the aluminum plate.



Not the VRM boards, the two 8 pin packages near the edge of the board please. They are in plain sight in the recent photo posted here ( https://bitcointalk.org/index.php?topic=170332.msg7436143#msg7436143 )

Elenelen, have you had a chance to check these 8 pin packages yet? I'm curious to know too.

that is exactly what I understand. but according to knc, it is not 'reconsiderable'.

not that it's 100% accurate, but from looking (squinting) at the pic of theNeptune ASIC KnC posted on their forum page ...  http://forum.kncminer.com/forum/news-and-anouncments/44256-neptune-asic-card
to me, it looks like they (the VRMs) are version BMR4641002 (40A/ 0.6-3.3V Through hole and Surface mount) I can't really make out the numbers/characters after that though ...

I'm batch 2 customer, do I lose second Neptune when I choose Hash While You Wait?

yes, once you sign up hash while you wait, you lose your second neptune. you can write to knc stating that you are not aware of the terms, they should change it back.

Probably more rigorous DIY is needed by replacing the whole metal-plate (and fasten the Tower in a different way).

I would probably go back to the old mounting method for the heatsink plus separate VRM heatsinks, I suspect that will provide a better setup since you can get better contact with the individual VRM heatsinks.

Yes that is the idea... and some additional Fan's as well.

if you're serious about mounting the radiator the old way (turn the radiator 90o, using the long bar/plate) and mounted using the two holes (the one to the right of the 10 pin and the other on the opposite side of the ASIC) - depending on which radiator they used as well, I've got the hardware to do it..
 
  I still have some of the plates, etc. to put it all together (similar to what I put together for the "Super Jup").
  I'm also working on a base/mount that you can put all the boards on (similar to the Jupiter)

  Any design ideas are very welcome!

I'm interested, I saw your work for the "Super Jup" and it was impressive! Are you thinking of something where we remove the Neptunes from their cubes and mount them on your base, plus associated plates and pieces? Or, are you going even further and thinking of a rackmount unit of some kind  Shocked

i also fell for the hash while you wait "order conversion," but contacted KNC and they have put me back on the 2-for-1 Neptune list.

Now just waiting for shipment.. I'm a batch 0 customer and order still shows paid.

I was thinking along the lines of a base with the boards mounted (5) five abreast, mounted using risers at the corners (10mm - 20mm) to keep the boards higher up to allow airflow underneath.  As well, utilizing the plate and spacers (if an Arctic radiator), to get that brick off the VRMs.

Just a thought ...

  Any design ideas are very welcome!

In my experience with KNC's 28nm hardware,  the primary thing stopping overclocking/better performance, was heat management.  The best solution was to make sure the underside of the board is cooled as well... even just placing a high speed fan on the bottom of the boards worked wonders.  I suspect that the neptune will be harder to overclock (the female pci-e connector and VRM's seem pushed hard on normal clock speeds, for one),  but having some sort of mounting solution to better cool the top and bottom of the board might be a good place to start. You could do this by having the metal sheet that you mount it raised slightly, and place vents underneath the boards (or cut little asic sized holes) to give room for some high powered fans on the bottom.  An even better idea might be to mount the boards upside down,  and give a place to mount fans on the top of the sheet, with holes in the sheet to allow air to go through.

If one were watercooling these boards,  I suspect that mounting them on their side might work really well also.  That way you could put, say,  a nepton 280L on the top side of the board,  and have a high powered air cooling solution on the other side/both sides to keep the VRM's and that PCI-e port cool.

Just some thoughts...
