If KNC won't send you a beaglebone you may just want to buy one off the shelf.  The model you are looking for is "beaglebone black" it generally retails for less than $50.   On edit: that won't work I forgot about the fact that KNC isn't connecting the boards directly to the BB it is BB---> custom control PCB ---> boards.


Based on your reported observations it would appear components are not being adequately cooled.   One thing I would point out is that the output and efficiency of a VRM declines as ambient temp rises.   The regulators used by KNC are rated at 40A when they are operating at <70C.  As the temp rises the rated output declines.  It is only 30A to 35A (depending on airflow) at 85C and the model being used is rated beyond 85C but the output would continue to decline.  The ruggedized version for example only outputs 20A to 25A (depending on airflow) at 100C.

do i really want to share my payout address?

Which blocks did you find?

and i am; with my lowly Avalon's. 

which paid themselves off over a month ago and continue ROI. 

and this shows another point that has been made.  The system runs great as a Saturn.  When I run just two of my troubled boards they produce those same numbers above but when added with just a third good board (best of the four as far as cores running per avg) then the cores start to turn off again on the troubled boards.

So, if I am able to run two boards at ~270, the one board solo at ~140 and even the board with the bad VRM(or whole die shut off leaving the VRM nothing to do, take your pick) which can still run ~100 solo....

THEN WHY if all running at once leads to terrible results?  Shouldn't that miner still hash ~510 like it did before I used .95 firmware?  Nope it sent it down to ~360 and best I can do now is run it around ~410 with .94, an auto restart script and cooling

KNC, how about you just send me two more BeagleBoards so I can make this a Saturn and two Mercurys?


the early part of the graph shows no cooling and lots of HW errors.  Cooling increased performance and then .94 increased it more over .91.
.94 allowed the miners to dip but switching .93 had them constantly over 500Gh yet hot.   .95 comes along and is presented by KNC team on website and here with Bitcoinorama as the firmware that solves boards with 4 VRM issues...  sure kill the watts but also kill the performance.   Also, side affect on my one miner was either a permanent shutoff of one die (48 cores) or the VRM go lame. Either case, you can see that the blue line shows it will never get to 500 as one unit again.  If I had two more control units, then they will (what I explained top of my post)

Keep on solo mining...

It won't be worth it by March/April.  Whatever $/GH might sound good on paper now will be worthless because everyone else will jump in on it too.  It's a mug's game.  Mining was only really worth it prior to the price explosion earlier this year before everyone and their dog wanted a piece.  The FPGA era was the last time this would be profitable for the average person...if u didn't sell.  The real winners are CPU/GPU...again, if they didn't sell.

view it as you wish.  

all i'll say is that i'm very happy with the compensation to the point i would feel guilty asking them to renew it, which is why I haven't.

yet they continue to keep me in the loop with what's going on.  Eduardo called me last night to fill me in on the latest and i continue to do my best to share what i can with the community.  

keep trolling.

I don't know, but logic dictates it is up until the point the customer file is sent to UPS and the manufacturing facility. From that point onwards it is part of the automation process en route to delivery; it enters the production line being assembled and picked up directly from UPS, or whichever intermediary they elect to send.

I find it enlightening that Hashfast did not renew their agreement with you for their subsequent batches.

Maybe your wisdom belongs on a separate thread where people have the option of reading it.

The production cost is largely irrelivent.  What matters is the market price.  What is 1 GH/s in hashing power worth on the market.  That gets more complicated due to the fact that it will decline over time.   Is 1 GH/s delivered in Jan worth $10 per GH/s?  Definitely not.  How about $5 per GH/s?  $3 per GH/s?   That is what the MPP is worth.  It isn't necessarily HF price in Jan but the lowest price available anywhere (all competitors, new and used equipment).  Obviously 1 GH/s has some value in the future.

No different than any other gold rush.  The rush will end eventually and mining will become boring low margin business.  Those with the most efficient setup will profit and those who are marginal will not.

'orama, do you know when November orders go into production?  When is the cutoff for refunds?  They used to say up to the day before your order is ready.  Kind of a shame that isn't the case anymore.

who admitted to trolling?

i think it's enlightening to determine this relationship btwn Rama and KNC as bizarre as it is.

What? Go out and check a company exists because it's a lot of money and I want to purchase myself, plus have a sniff around as it's inline with what I studied my post grad in and I have an interest in Bitcoin.

Report back and share what I found out, which could then be confirmed independently by yourselves.

Made to feel kind of responsible by people here on the forum constantly asking for more info, and Sam wanting me to handle communication, due to the fact Sam, Andreas and Marcus are overloaded with work and a geoups of IC whizzkids with Aspergers should never be put in the public spotlight. Refusing to do so on my part on an employed basis until they have a proven working product.

All I ever did on their side before, and after the open day was make some solid suggestions; this is a burnt community, make sure you under promise, and over deliver, get on Board with Life on Bitcoin, etc.

I'm not f-in stupid w.r.t. my responsibility. All I have ever wanted was;

1. No one getting ripped off, so inform and make logical choices. Though entirely your own fault if you won't read and research and make educated decisions for yourself. Those that listened to me are clearly happy, though never have I told anyone what to do, just what I was doing.

2. Wanted to see a real engineering firm deliver through talent and not spread marketing lies to tie up people's funds under fraudulent false pretence.

Well, I respect your honesty for admitting you are now trolling. Who knew trolling had to be voluntary?

Was really hoping for some free miner protection thru firmware upgrades because of all the VRM's on the boards.  HashFast customers may not be mining yet but that "miner protection" puts them in a more comfortable position.  Then the difficulty will raise that much faster if most customers paid for it.  But then of course they had to raise the prices even higher for "miner protection"...lol  Like Puppet said, the chips are probably $50 each.

BFL, BitFury, KnC, HashFast...the only people making money in the ASIC generation.

+1

during the time i got paid to sell out Batch 1 (18 days) i NEVER entered this thread, iirc.

and if i did for one or two posts at most, it wasn't to troll.

Thanks! Give them a phone call and get a live count from the factory floor :-)

They said 700 on Fri I think.
I was told around 1,000 last week when I stated this in the forum.
I don't know, Marcus and Michael are at the manufacturing facility now determining that, but I don't see why it cannot be this week now device issues seem to be more or less sorted with the last update and since General Electric sent their Critical Power guy to double check and confirm the PCB met all their recommendations.
