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 ...

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.

Case1:
I don't think so. It's only an needless try to get out more of this machines. But it will not be possible, because you can't
get more out of an old horse. Shocked

It`s only wasted time and electricity.

Case 2:
They make it for fun

Case 3:
narrowness


Most cases 1 and 3 together

lol guys!

I'm only frustraded about the frankenjups

p.s. I worte today to the chamber of commerce and now waiting for an answer

May be difficult now since it has been started. Best chance is to contact them by phone asap, and cry a little bit. If it doesn't work, try yelling.

Maximum operating temperature of the BMR46x series is 125 C.

http://archive.ericsson.net/service/internet/picov/get?DocNo=28701-EN/LZT146435&Lang=EN&HighestFree=Y

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.

Yes, but no sorry: I cannot read anything (all is covered by the plate or foam).  Next weekend I will disassemble one box... I will post then.

I have it running now (I guess I'm the first...)

It does: about 3.3 Th  and 1950W at the wall (the internal ASIC-monitor gives about 1440W...I have no idea where the difference is going to).
The chip is running on 475 Mhz (and can be set to 500 {not tried yet}).

There is one new thing on the controller-board: on plug-6 there is a small display-board which gives info about the IP-address and Hash-speed (very nice)... but this means as well that 5 boxes is the maximum.

The one PCE-power plug isn't running hot {the fan is indeed pressing air through the hole}, but the cables are 44 degrees Celsius.

It appears they are actually shipping en masse.

did anyone notice if the hashrate spiked then dropped recently? <smirk>

Just some thoughts...

or if their was a picture of the bottom of the board...you could plan out one big heatsink for the bottom that would raise it up and then you could just put a high powered fan in front and would cool both top n bottom at same time...or just put copper vrm heatsinks on top n bottom like i did n use raisiers like i did...but i fear with the already high heat...you need above n beyond just the small heatsinks...unless maybe if you use server grade fans lol

could also just solder another female pcie connector on the bottom couldn't ya? idk anything bout that thou

kinda curious if that first nep. guy how his vrms are holding out? seeing any black smd caps yet?
