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

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...?

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

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.

Well the miner that arrive 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...

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..  

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.
 

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

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;

Potato tech maybe.  (Just kidding).

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

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.

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!!!!
