What are you on about? each chip is pasted prior to assembly an the manufacturing facility. They have a special metal grid that lies flush on top of the chip and the paste is spread thinly over.

thanks for that detail - some were saying they saw differences on the amount of paste.   I didn't know it was automated but it is a sensitive part of cooling so all eyes on that when temps are all over the place

why is the miner setting page totally blank?

This happens in the original release if you have added more than one pool to the cgminer config file.

EDIT:

Throwing them around like the box in my pictures ??

mine as well, even after I begged them to ship the fans and heatsinks unassembled





one or two out of 8 ain't bad for these guys!!!!

Beats the hell out of NOTHING!

OK, so I'm running at a steady 275Gh/s average(Saturn) with firmware ver 9.1.
Is there any reason to flash the 9.4 onto it...?

"But surely if we hand write "fragile" in marker pen, they'll know it's a piece of delicate electronics worth $8000 and handle it carefully?"

Holy shit! There's actually a joke that goes along with that, which appears a little insenstive now. And as a result a miner was actually packed in that box by mistake. I actually drew that on there myself, but I swear that left with UPS in mint condition;



Thanks for posting that, that actually appears to have been damaged purposely and maliciously, and as far as i'm concerned should burn UPS's delivery contract.

And no Xialla, get your facts straight KnC is NOT ignoring complaints, they've ordered a lot stronger boxes, and are awaiting delivery of them, as mentioned earlier.

I see, with the end pieces of foam, there are voids under the sides of the box that can easily implode to force.

[aspeer]

Any idea when someone is going to fix the A: capthca on KnC Forums for pass recovery. B: Fix the firmware because I've got a lovely jupiter maxing at 128GH/s...

If it ain't broke, DON'T FIX IT!

My friend worked at the Airport for UPS.  They would go out of their way to fuck with anything labelled fragile he told me.  Such dicks.  I hope that miner is okay.

I agree....just checking...hehe

Boise .... But we had tech.

Potato tech maybe.  (Just kidding).

LOL!

I'm not an idaho native, the jokes don't bug me. I called Boise "spudville" for the whole 14 years I lived there

The perception of "hickville" does bug me, though, just because it isn't true. It's true of a lot of Idaho, but Boise is a serious modern city. Pretty nice place, actually.

Right now, I live in Mountain Home and work in Boise. That needs rectification. Mountain Home has no mountains, no entertainment, little commerce, and no charms. It's only virtue is it's cheap to live here. Ok, two virtues, the 'Net service here is pretty spectacular compared to most small towns I've been in. Unfortunately they're all dead, but the people who picked the flattest spot in Idaho and named it Mountain Home ought to be killed. And resurrected, and killed again. And again.

After a solid 24 hours running v.94 near 550 GH/s my jupiter just dropped to 400(ish).  Reboot didn't help,  temp looks normal.    Appears to be due to huge HW errors..   20+%

Giving it an hour to recover but looks like it isn't going back up.  Lost 150 GH/s..

Well the miner that arrived inside said box is doing just fine...




And no wonder the box was so screwed up - 'Orama personally packed it.  Heh.  By mistake?  You mean I got an extra special one?

Hey - I got the magic box - care to tell me the insensitive joke?  You're welcome to PM it to me...

my miners after delivery:

In the first photo the upper left hashing board is it just a camera trick or is one of the heatsink mounting screws missing?

It looks like there are two holes: One close to the radiator and one at the end of the mounting bracket.  The ones at the ends of the mounting brackets are the only ones used.

Bitcoinorama, First of all: THANK YOU, for your great reporting!

But now to the bare facts:

I have received my Jupiter today and tested it thoroughly (0.91, 0.93 and 0.94) and this on all 4 ASIC-boards as one Jupiter-system, as well as each ASIC-board separately (only connecting one board at one time). And found huge differences in the boards.

Actually only one of my Jupiter-boards is working very well, one is running more or less OK (has some Core disables), but 2 are just bad. Together they make only 390 Gh/s (the good one is 135 Gh).

Be aware that this Jupiter is cooled very well (in a Server-room with 18 C, without the case-top, and even an extra Fan blowing 18 C cool air into the Jupiter-box).  So hardware-errors due to heat problems are impossible.  Still the bad boards have about 30% of bad cores…. Reducing the optimum hashrate from 140 G/s per ASIC-board to 100 or less.

Sure the FW versions 0.91 to 0.94 are trying to “stabilize” the system, but actually it’s only disabling the faulty cores per ASIC. This disabling results in less reporting of HW-errors indeed, and so reduces the Hashrate performance as well (by disabling 30% of the cores). This disabling is also noticeable if you look at the Temperatures of the ASICS (and their Watt use). See this list (sorry, I don't know how to insert a screenshot into this post):

ASIC slot #1: 57 C
ASIC slot #2: 36 C
ASIC slot #3: 38 C
ASIC slot #4: 41 C

the one with 57 C runs very well (on its own about 135 Gh).

So looking to all other posts and reports about Jupiters running 550 Gh and others like me running only 391 or lower: You simply are lucky if you received a Jupiter with 4 good ASIC-boards (then 4 times 135 is about 540). If you have one or more not so well manufactured ASIC-boards you end up (much) lower.  I’m afraid (please ask Sam for me) that software updates will NOT solve this thing. We need to replace the hardware: more boards per Jupiter (tested at KnC before shipping) that are capable of running 140 G without Hardware-errors.
 

Let's see how do they address this

Again thank you Bitcoinorama for your reports. Too bad you only got 2 BTC as donations. You will get more!

KnC should take lessons from TAV packaging for the Redhash unit. The box is 3 times the volume of the miner with extra heavy duty cardboard and 2-5 inches of spacing between the outer box to foam to miner.

I'll take a picture of it and post. I am sure the TAV packaging wasn't cheap but my unit traveled 3500 miles between 2 couriers and was intact and no apparent damage to packaging.

the packaging KnC is using is shameful for a unit that hashes 5 times as fast and 3.5 times the cost.

I am close to 24 hr mark myself.

So far the performance is the same once I supplied acquitted ventilation.

There's a town in florida called mount dora. The highest point in the town is 144 ft above sea level.  It would have been better named 'small sand dune dora with no ocean view'

Are these 40A Digital MegaDLynxTM: Non-Isolated DC-DC Power Modules running above 50% overload? Some of mine are above 60A.

Mine are all running with > 50A -.-

No . stay away from all but 0.91. I found it the best by far (Saturn as well)

Bitcoinorama,

I appreciate all the useful information you are providing on this forum. Keep up the good work!

You said:
"Any customers that purchased for October are being delivered in October. Any customers after, will get theirs in November, after a month’s gap. No special treatment."

Do you know if the month gap is an artificial delay to protect the profits of early orders, or is there another reason for the month delay from mid October to mid November?
