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.

First Batch (with many unknowns): Supposed to ship in September, ended up in Oct/November.

Second Batch (with everything figured out): They were to ship in November, ended up first week of December.

This is kinda misleading. First batch were supposed to ship by Oct 15, and they did ship around half of orders before that date. They never guaranteed anything in september, it was just best case scenario. And second batch started shipping late november, not early december.

What?

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.

... with a hashrate of 3-7TH, depending on how much power you can supply.

Sauce for 7TH?

Cheers.

It's an estimated based on prior performance levels, which more than doubled from the conservative design spec.

KNC announced 3TH would be the minimum, with "much more" hash depending on your power capability. This is what appears to be their first design toward industrial/commercial rigs. Several of us have done the backwards math for the TH/Wattage. If you search you can see the reasoning.

I personally believe 7TH is an upper limit, with 5-6 realistic--but I wouldn't make a buying decision based on anything other than 3TH.

I guess thats based on the premise that because Jupiter was originally expected to be 350GH/s (actually the initial launch thought only 250GH/s) but in the end the November batch came out at near 700GH/s

Extrapolated from GH to TH then you get 3-7TH

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?

Couple of weeks? They didn't start arriving in many cases, until end of October, with next day shipping. Mid September was the first prediction, then Sep 27th, then the end of September.

Late is late. Granted, this was their first batch with unknowns, so forgiveness is easy. As I stated.

You would imagine, but they still had delays despite that, likely because they kept changing the design. And this 2nd batch has had more apparent DOA's and failures than the first, which indicates they rushed it out the door. This doesn't get forgiveness like the first batch.

Hence, my safe worst case scenario of August. Worst case.

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.

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.

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.

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.

Hello,

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

Thanks

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?
