OK, I have a modified-DIY-box below 70 C and running on 500 Mhz:  How do I get above 500 Mhz ? Contact KNC, maybe they'll tell you, or add an option in the next firmware. Could you post pictures of your set-up ? Edit : Would these 20mm spacers work ? How many do you need per box ?

Mining should be for everyone small miner hobbyst or proffecional level.
Its the only way bitcoin will be spread to the world.
otherwise the five-seven big companies mine keep the BtC and we just sit and wait...to be mined
and why to spend my money for something else already premined like gold!!!
guess what will happen if miners will not be sold to ever jane and joe.
There are a lot lot of people that want to enter mining to see what it like and if it works
I thought also before some months ago.
I purchased a USB miner and checked the bicoin calculator
A week later checked the mined BTC and said Ok it works for me lets go to buy another bigger miner
and the story goes on
guess this way works for many others too.
very well said ... I fall into that category, and I've only grown. I'm now at 15Th/s |

No, sorry Ski72.... You need something like this:  wonder if that is the same size as a cpu cooler mounting bracket? Yes. I import it (the pic) into AutoCAD and the board is the same size as the Jup boards (I compared them side by side, dimension wise, in AutoCAD), and the holes are in the same places, just a different layout of the VRMs. |

No, sorry Ski72.... You need something like this: That's how they are mounting it now, yes, with the airflow in that direction. The way it is/was mounted on the 28nm board, is with the radiator turned 90 o clockwise, and the front/face of the radiator in the direction of the PCIE and ten pin connectors. Basically you'd take the board out of the box, mount the radiator as above, and put a fan on the radiator. You're still getting the same airflow across the radiator for cooling purposes, and take away all the foam, more airflow around the VRMs. Also, looking at the other pics from crash and tzortz, you could then put little heat sinks on the VRMs. Just a few thoughts ... |

I am sorry but cannot understand the usage of your plates.
Can you please explain a little more?
the plate/bar is not as large as the one currently installed on the Neptune, nor will the foam be intruding on airflow over the VRMs. It is the same design as was used to hold the radiators and ASICs together on the Jupiter. This how the Arctics were mounted to the ASICs on the Jupiter ...  and using only the two holes, front and back, the end result opens the board (VRMs) for better air flow ...  off to sleep ... hopefully tomorrow is a better day for "receiving"  |

Pic of the rest of my h/w here: http://imgur.com/a/mRbMZCheers, QG I must say a very impressive (collection) progression of your hardware from diff 8.97M to 13.5G ... I haven't been mining as long as that, but I share your passion for getting your hands "dirty" ... lol  |

Underneath??
ya just picture the copper heatsinks on the bottom...don't really need a picture for that  well the heatsinks will help even more on bottom too...spec. with neptunes since they are already oc'd so much it'll help you get the most outta it i think you can't do both i don't think...ya the plate is alittle hot, but the reason its hot is cause the vrms are screaming hot...i really don't think its sucking up the heat from the vrms..i think its hot just from being around the vrms...oh and those gray things block air flow and trap heat in...and so does the case  hope this helps also i made the mistake of leaving the grey pad on 4 of my modules and only been ran for few weeks like that but you can see the damage it did...the caps are dark...i mean almost black now  so i picture in a week or so with all those neptunes heating up, all vrms will be toast and probably break...that grey thing does nothing but heat up the vrms more...or maybe it just transfers the heat to the smd caps...idk but if i was a neptune owner i wouldn't be running them in a knc designed case...they may make a good 28nn chip but they suck at designing cases or heat management Thanks for the info.... Now I think of it: the plate is heating up from the Tower (and ASCI chip) as well... but removing the plate will also tumble down the Tower >> that's a major DIY project... Elenelen, I'm sure you know all about the "Super Jup" fiasco. It looks (from the pics you posted and the info. KnC has show on their site) that the boards are the same dimensions as the 28nm boards. I made "bars", the same size and with exact location of all the mounting holes on the bars used on the Jupiters, "Super Jup" etc. PM me and I'll send you a set of materials to mount the radiators (w/o all the foam and huge plate covering the VRMs), and risers to keep the board off the base. One item though, which brand radiator did they use - Arctic or Cooler Master? I know i'm a newbie, but if you look on the KnC forum, http://forum.kncminer.com/forum/next-generation/hardware-designs/39700-mounting-hardware, you can see what I put together, as well as everyones input.  I hope I can help ... (Sorry the pic is so big ) |

Probably more rigorous DIY is needed by replacing the whole metal-plate (and fasten the Tower in a different way).
I would probably go back to the old mounting method for the heatsink plus separate VRM heatsinks, I suspect that will provide a better setup since you can get better contact with the individual VRM heatsinks. Yes that is the idea... and some additional Fan's as well. if you're serious about mounting the radiator the old way (turn the radiator 90 o, using the long bar/plate) and mounted using the two holes (the one to the right of the 10 pin and the other on the opposite side of the ASIC) - depending on which radiator they used as well, I've got the hardware to do it.. I still have some of the plates, etc. to put it all together (similar to what I put together for the "Super Jup"). I'm also working on a base/mount that you can put all the boards on (similar to the Jupiter) Any design ideas are very welcome! I'm interested, I saw your work for the "Super Jup" and it was impressive! Are you thinking of something where we remove the Neptunes from their cubes and mount them on your base, plus associated plates and pieces? Or, are you going even further and thinking of a rackmount unit of some kind  I was thinking along the lines of a base with the boards mounted (5) five abreast, mounted using risers at the corners (10mm - 20mm) to keep the boards higher up to allow airflow underneath. As well, utilizing the plate and spacers (if an Arctic radiator), to get that brick off the VRMs. Just a thought ... |

Elenelen, have you had a chance to check these 8 pin packages yet? I'm curious to know too. not that it's 100% accurate, but from looking (squinting) at the pic of theNeptune ASIC KnC posted on their forum page ... http://forum.kncminer.com/forum/news-and-anouncments/44256-neptune-asic-cardto me, it looks like they (the VRMs) are version BMR4641002 (40A/ 0.6-3.3V Through hole and Surface mount) I can't really make out the numbers/characters after that though ... |

I'm very interested as well. If you can get the Spondoolies team involved to back up your word (and price), I'm in ...

Damn. I just checked back and saw the news ...
I vote Spondoolies (if possible), I've got (3) three SP10 Dawsons, and despite the noise, they've been hashing great ...

yeah, I got "waldohoover`" ...
on a serious note, any headway with the real deal?
Thanks for your hard work!

not a problem, there isn't that much of a cost difference ... Thanks for your help!

What's the point of bitcoin if you have to be so paranoid?
I put this post in the Newbies area for a reason  I believe that bitcoin will someday be orders of magnitude more secure (and more valuable). If you buy bitcoins now, you are an early adopter getting in while prices are cheap and betting that security and utility will improve. In the meantime, yes, you must be absurdly paranoid. These websites cannot be trusted any more than you absolutely have to. To actually hold onto your coins long enough for your investment to pay off, you need to push the paranoia up to the tinfoil-hat level. This is the price of being an early bitcoin adopter. it has definitely become more valuable, but secure not so much IMHO ... it's still very easy for someone who is too trusting to be scammed by someone who is too good at doing so. |

Hello all,
I know I'm a newbie, though I've been mining KnC from the get go. After the Super Jupiter fiasco I have decided to go a different route. Though during that time, the main problem people had with the Super Jup was the fact that the Arctic A30/i30 radiators weren't mounted to the ASICs properly. I run a small shop and quickly reproduced the original mounting solution for the community. I know the last thing people wanted to do was spend more money, but in the short time frame and with keeping costs as low as possible, I had a lot of happy customers. If you are interested in verifying, you can join the KnC forum and check it out. I've got the same handle.
I received my Habanero a little over a week ago and I'm in the process of designing an enclosure for the Habanero. I am open to any and all suggestions, as well I've been following other users thoughts regarding air flow around the board, whether push or pull is more efficient, etc. Though I know a few people who have received a completed HashFast product, most have run them with the case open. That may be the best solution, though with all the components mounted in a logical and efficient manner.
Good luck to everyone in their quest for quickness ...
Ski

But that's not any fun. Now is it?
Trust me. More BTC = More Fun. actually making roi btc then reselling the hardware for the same you paid or more is actually the greatest and I play with KNC hardware to keep it on topic....geez. forget KnC hardware and forget the datorhall... WTF?... YOU CAN HAVE YOUR OWN FARMastounding... to think, if enough people buy into this, hashrate is gonna spread. collectively we could put that knc d/c in the lower echelons of mining farms. i'm off to the bank, it's my duty. I agree ... going to get an SBA loan, a few government grants for putting in my time in the service, and load up on those babies (  sarcasm and wishful thinking  for that kind of hashing power NOW ... ) |
