Let's hope that was KnCMiner's data centre.

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>

  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...

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?

I took the bait (while you wait) and spit it out.
My 15Kilogram box is in Germany now (headed to Chicago area).

THANK YOU FOR THE HEADS UP IN THIS THREAD!!!!!!

Had I not spit it out I would have traded 1 neptune for under 24 hours of hash while you wait.
It shipped same day as my HWYW would have started.

They make it easy to dislike/distrust them.

Perhaps I neet to get fitted for a hater hat.

On another note!!!
FrozenCPU now takes bitcoin!
They sell water cooling equip.

It's too bad RAM waterblocks are so expensive, 10-15 of them would tame a neptune's VRMs.
(I'll try making my own out of copper tubing)

I waited till shipping notice before installing new electrical load center.
Around USD $150 in parts if you DIY! Smiley

 I believe that the network hash rate is unknown and must be statistically inferred from number of transaction blocks found by the network in a given period of time taking into account the current difficulty.  Due to the probabilistic nature of solving a block, there is some inherent variance (which is also called luck) in the network hash rate.  This might be why it appears to be changing quickly.  I don't think you can pin it down to KNCminer at this time but certainly if you watch the rate over a longer time-frame it might be more telling.

@tolip_wen:

great idea, I don't know what diameter for tube, but as long as you flatten them on the one side and you could bend the tube in a U-shape to touch all the VRM's

might need very high flow, but it doesn't need to be fancy.

btw, pretty sure the chip can be safely air-cooled. those tower CPU style coolers with the heatpipes are incredibly efficient.

Good idea!
Just watch out for mechanical strain on added connectors as they may only be held in place by solder.

I plan to solder ALL power wires directly to the PCB.
Connectors are a potential point of failure.
12 connectors per PCIe power cable on a modular PSU
(modular sux for performance and safety on power hungry miners)


I have 2 consumer PSU's that have smoked connectors from my Oct. adventures.
This is what happens when ANY one of the pins of a connector fails, the neighbors have to take up the slack.
The 18 gauge wire on consumer PSUs is not up to the task.

Poor KnC only found 9 blocks today. That's over a 50% drop from a few days ago. What are they going to do only making $120,000 a day? We may need to start a foundation to support the starving bitcoin hardware manufacturers.

y u miners no mine while shipping?

anyways, I'm glad to at least have a little piece of that hashrate when it floods the network again in a couple days.

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.
