If I did order 1 Neptune now to pay later, I mean latest 1 week later.  not 5 months.

As I can remember, the Jupiter's were meant to of started shipping end of September, but they were a couple weeks late, not 8 weeks late.

Also, don't you think now they have better understanding of the whole manufacturing process and their factory is fully setup with full workforce.  Unlike before (first time round) they were setting up and adding staff as they went along.

they have to have more experience this time round, no?

Agreed.  A fully functional manufacturing facility with SMT machines that work not for eyewash.  On the other side of the balance is the question can the planned ASIC be done on the intended smaller scale and expansion.

Are you looking at a different KNC news feed than I am? And the "early bird" folks back in June/July would dispute your estimation of the first batch, which was to ship/arrive in September.

What?

This post is entirely wrong.

I ordered a first batch saturn. I've been following their news closely, and I know that when I ordered one in June they said orders were expected to start shipping in september but all they PROMISED was to ship it before october 15th, AND THEY DID, I received mine on the 15th exactly.

You may actually be the first person this ever happened to then, and with an entirely different promise. Some of the early-bird Jupiter folks had a different story to tell.

So, out of 10,000 delayed orders, we have 1 which looks good. That still doesn't shift the mean of delays.

Problem is that "shit happens" like having to switch the VRM component at the last minute because they couldn't get the original ones, now sometimes that has a positive effect (Hash rate) and sometimes it has a negative effect (delay)

Certainly their delays are getting shorter, probably due to the manufacturing process becoming slicker.

But there is always something that can happen, it "appears" that when pushing the envelope with the Jupiter design that the variability of the production process can introduce perhaps tolerance problems that may have caused performance issues some machines.

Its hard to remember that to all extents and purposes in any other industry these would be highly experimental one off production runs. I mean we've only had 1 batch of October machines and one batch of redesigned November machines. In normal production runs they would be at the third or fourth batch by now and would have tweaked the production process to account for any anomalies that the discovered from earlier batches.

+1, excellent post.

Hello,

Please switch pool, Eligius is encountering lots of problems recently, not only with KNCMiner hardware.
Try BTCGuild, BitMinter or such.

Thanks

Does anyone know where I can buy more thermal blocks of the same size as what is in the November Jupiter that cover the new VRM's?  Mine didn't come with any and it performs like an October Jup.

Been looking myself, they are about 1cm thick

Damn I'm going to have to open mine up and put it back.

Is your Jup performing the same with or without it?

Hard to tell, I think its worse without it, certainly I have one board that seems to get ERROR4 VRM errors which seem to be heat related. Bertmod isn't reporting it to be running any hotter than my October rig and this Eligius pool issue isn't helping with the diagnosis.

Thanks.  How do you see the "ERROR4 VRM"?

You should just switch to btc guild.

Anyone know how to get cached copies/screen grabbed images of the KNC site from back in June/July/August/September. Also any modifications to their order TOS.

Anyone thought about building a custom case. I was thinking about a better (non-rack) design which is visually appealing to turn the rig into a spouse friendly space heater, internally mount the PSU (and rats nest of cables) and at the same time improve cooling.

ASIC boards are ~5" wide.  Optimal airflow would be units side by side in a line. Now put the PSU (on its side) at the end.  This would make the case ~24" wide.

Standard PSU is about 7.5" deep plus you need some room for routing the cables so say 12". 

So imagine a wooden box 24" x 12" x 7".  The entire front and back would be a grill for improved airflow.  The fans includes are pretty crappy so I think by upgrading to some higher airflow (but still low volume) fans one could get rid of the "intake" fans.  If needed it should be possible to mount a fan on each side of the heatsink in a push pull config.

Excuse my horrible ASIC art but here is a top view.  Front and back are mesh screens.  Arrows indicate airflow.  PSU intake could be on the side of the case or if case is made larger draw flipped 180 to draw from the inside.

Code:

|---------------------------------|
|   |      |      |      |        |
|   V      V      V      V        |
|[ASIC1][ASIC2][ASIC3][ASIC4][PSU]|  <--
|   |      |      |      |     |  |
|   V      V      V      V     V  |
|---------------------------------|

Still a rough idea at this point but wondered if anyone had considered something like this?

Newark, Digikey Mouser.

For example:
http://canada.newark.com/webapp/wcs/stores/servlet/Search?st=thermal+pad&catalogId=15003&categoryId=800000006679&langId=1&storeId=10196

They can ship overnight.

Otherwise a local computer dealer may have the thermal grease or the pads.

Thanks but they are so many options!  My head asplode.  We know it is 1cm thick I guess...which is 10mm, the largest they carry is 2mm it looks like...

I literally came up with this same idea a month back when looking into the KNC design. Makes it more compact/easier to put in places (especially under a couch haha, blow warm air on your feet). I say go for it. If I can ever get more modules, I might. My mercury wouldn't benefit lol

If anyone wants to work out a 3D design that uses elements smaller than 20x20x20 cm (and perhaps square wooden  or aluminium booms), Id be happy to try 3D printing it.

Has it been confirmed that those are actually termal blocks to cool the VRMs?
They look far too thick to be effective, and I have never seen any that thick before when looking to buy pads for GPUs and CPUs myself.
If they were 1mm pads on either side of a bar of aluminium or copper I could understand it, but at that thickness any soft/foam material is more likely to work as an insulator.

I have checked my November Jupiter and it does not have them.
Hashing happily at 657 GH/s presently, pulling 855 Watts from the wall through an EVGA 1000P2 PSU.

My guess, without further info, is that they are packing material used to either aid assembly or to protect the VRMs during assembly operations.
That would mean that somebody forgot to pull them out before shipping. 

Good luck in your search.

I switched to ghash.io, and immediately my HW errors dropped below 1.5% on all machines and have stayed there. Bye bye eligius I suppose!
Anyone have a good starting point for the difficulty setting with ghash? I'm at 256 right now.

I pulled one off, its definitately thermal pad material. I've also measured the temp of the vrm under the thermal pad and the same VRM's with the thermal pad removed and without the pad they are definitely hotter. They are also on every board in the same place in my Nov Jupiter. Maybe some machines needed them and some didn't?

512 seems to be optimal for 550GH/s

There is a thread here https://bitcointalk.org/index.php?topic=274023.0

In which ckolivas suggests

TL:DR
Set your diff to your worker's hashrate in GH / 1.4

555/1.4 = 396 Difficulty, but not sure if you have to round it up.

Thanks for all your efforts on this D&T.  This worked perfectly on my dead machine as well.
