Ya, your right. I should have got something better. This piece of garbage only runs at 700Mhs and draws so much damn power.. 1300w. A pile of junk. Im sending it back.

KNCminer is done selling hardware... until they are done with it on the cloud selling contracts, and they are obsolete.
don't bother mate... people work too hard for money these days.
You may end up seeing some old neptunes after all the solar 16's have been deployed; but seriously....the train left the station over a year ago.

yeah ..but i did not consider that when i set up my stuff see link below

http://lostgonzo.imgur.com/

you look at where my bench is setup..i need to push the air out ..and the windows are above...thus i need to probably seal with plywood and just mount the attic gable fan with thermo and shutters so rain won't dump on the bench below....now if it probably would not amount to much but with the pi controller sitting out in the air like that ...that probably is my better option...on your link above they say they have a way with their storm guard system to shut the window and keep the fan in place...well won't work for me i may not be home if a storm pops..not a big deal to do my way...but in hindsight probably could have put the bench in a better place away from windows in basement..(then I’d be yelling that the air flow was worse or something there) ...but yeah main thing is just get the hot air out...a guy on ebay has this setup....which would work but I’m not too excited about in my bsmt windows...

you could probably rig something with wood to do the same...on a 2nd floor window this would work on a basement or 1st floor window where someone could just pop the plywood and walk off with your miner..er not so much...

not a big deal ...like all things ...I will have to do this fan stuff around May I guess when temps motivate me

by the way any fan you setup you can either wire in a thermostat option (common look for gable fan thermostat) or just get the plug in kind that kick on at a certain temp with your fan plug'd in to it before the wall plug in....the cheaper is probably the attic wire in version for attic fans..just jury rig a box from whatever fan you choose would work also

I will post pics of my fans installed next week, as when I got the titans, and they started thermal throttling to <350Mhs I knew then they were thermal controlled, and that meant the more cooling , the more speed. So, my setup at this moment just has zip ties on the fans and is not ready for presentation. I am waiting on another order of KNC Titan to come in, in about 10 days, and I will make it presentation worthy and pro. A 252 CFM is fan is NOT for everyone. You better have a room you never go in. They are so loud they will hurt your ears. Im not kidding. Before you run out to your nearest computer store and buy 10 gut wrenchingly loud fans, you should watch this video of the SMALLEST version of this fan, then imagine 10 of these together: https://www.youtube.com/watch?v=on9pvkJ0P1w

Guys ive owned computer repair shops in Vegas for 20 years. Thats how I understand this stuff. There is not much im good at, but Im a master of electronics, and today setup massive asic farms in warehouses for a living. www.bitcoinlasvegas.net

Im trying to upgrade my BFGMiner version to 5.0 on my KNC Jupiter following the README instructions in the zip file.


Everything works till the last step however if the miner is rebooted, all the changes are reverted back to how it was before the upgrade. The directories and everything disappear and goes back to the stock version. Any ideas?

I am using these instructions

Man, you could very well be telling the truth, but you defend criminals and belittle all of us who have been screwed by KnC, so I have no reason to believe you.

That's a nice idea there, the temp controlled fans. I had been thinking of getting one of these: http://www.ventingdirect.com/air-king-9166-20-inch-3560-cfm-whole-house-window-mounted-fan-with-storm-guard-housing-from-the-window-fans/p441363 to suck the heat out of the basement, but I'm having trouble justifying the cost. I think I'll just go the cheap $20 20" Box fan route and slap it in the window, lol. Right now, in these cool Spring temps, I'm just using the old attic fan to suck all the heat from the house and basement. It's a 1960's R&M Hunter fan, 10,000 CFM. Can't use that in the summer though unless I want to suck all the A/C outta the house, lol.

FYI my TITANs have been having good luck at http://manhattanmine.com/ the site owner is always on top of the latest coins etc. TITAN friendly ports 3334

they are shipping the last of the 2nd batch 400mh titans..i heard from folk they are canceling the 2nd batch 200mh Titan units and refunding...at that
point from what I understand they are gonna fold shop on the consumer side of the biz..lay off folk from sales/shipping and tech in sweden and just
use their new 16nm chips for their own use on their data hall in iceland....using the big IPO $$$ (richer newbies more $$$ same bait and switch game)

there will be NO other equip for sale by KNC to outsiders unless you are in their IPO/data hall setup and/or do cloud hashing thru their site

i expect when their 16nm chips hit the data hall ..probably in a month at the latest you are gonna see  a pretty good 'pop' in BFL difficulty

Sam Cole of KNC has said he wants KNC to control 40% of all bitcoin mining by 2016

 

just saw kncminer delivering within europe which would be optimal as i am also living in europe. Are they still producing hardware? i checked their website but just noticed they re producing 16nm chips and got investment from Accel Partners (15m$). So whats going on exactly? I can't see any webshop or anything. Is it still possible to purchase (profitable) mining-hardware within europe? Is it even possible to make a RoI within a decent timeframe? any help/info is appreciated.

I don't believe it either, esp when his screen shot is showing 2 pool workers

btw, in the winter time my cubes were running around 60c and there was no increase in speed

let's see a bfgminer screen shot too

yeah a pic of your push/pull fan arrangement would also be helpful........imho if you would

Please could you show me a screenshot of your main knc screen showing the "Mining status" and the "HW status"
I really want to believe you and talk about this too but i have to see it to believe it 

OK i will try that (still not sure about the regrease.....) I'll try it the other way around from the bottom up 50mh and work my way back...setting with the voltage the same as it is at 300mh and just see what happens working from low to high direction this time around just with speed....( i assume this is what you mean) ...what the heck I break the cube good I'll HAVE  to send it back as an RMA to KNC...the choice would be out of my hands at this point (i still heard they charge you $400 usd a cube....so hell that probably would not pay either)....


fun times stuff to try

Voltage stays the same, and start at 50mhz, and work your way up. Eventually finding the highest speed that die can handle and be stable. Lowering voltage might make it unstable. Raising voltage, will create more heat. You can also take it to a local repair shop and show them what you have, and they should be able to regrease at a fair price.

What I discovered on titans that is quite unique is the lower the temps, the faster they run.

Vegas

at the present time i'm not brave enough to probably take the cube apart and regrease..so as an alternative to try (i've done this before with no success) is just set the speed down on the bad  die and lower the voltage as well? that is what i tried....but if i read the above correctly you would leave the voltage above the SAME and just underclock downward to see if something takes?
 again making sure this is correct...go down say to the 50mh setting and start from there but I always assumed you lowered the voltage accordingly? but maybe not?

clarify please.....i've dorked with these dies so often in the past i forget exactly what i've tried need a process step by step

Could you show me a screenshot of your main knc screen showing the "Mining status" and the "HW status"

Im glad to help where I can.

Ok.. first thing you need to understand is.. failing dies is a PHYSICAL problem. So any fix will not be a professional permanent fix, and will probably become future problems. The real permanent fix is an rma to Kncminer or a new cube.

It is entirely possible that if 1-2 dies fail, and then if you let it sit for 20-30min, and reboot again, and dies return, its most likely a heat issue. There lies a MASSIVE heatsink on top of those dies, and titans do run quite hot. Its quite possible that one or 2 of the dies have dried up thermal grease. Its very easy to remove that massive heatsink inside and clean both the bottom of the heasink and the dies, and regrease. I recommend Acrtic silver for thermal compound. After youve done this run your rig. Watch the temps , if one cube is much hotter than the others, and its the same one that has the failing dies, its most likley a heat issue. I dont like to see my cubes go above 60C, and they usually dont.

If cleaning the dies on the bottom does not fix, then do NOTHING with voltage! Some have said that raising the voltage has brought the die back to life for a short time, BUT now your adding more heat and stress on the die. If I were you, I would look more at lowering the speed. Set the die to lowest MHz setting, run for 1-2 hours, if its stable, then bump it up one more notch , and watch for 1-2 hrs, until you reach the speed where it stops working, and then you lower it down 1 notch.

Hope this helps.

btw Ill say it again for those that dont beleieve me, my titan batch 2 DOES run 24/7 at 600-700Mhs, and NEVER goes over 55C. Here is the secret. http://www.newegg.com/Product/Product.aspx?Item=N82E16835706015&cm_re=252_cfm-_-35-706-015-_-Product. 252CFM!! THE most powerful fan for computers and such. One in the front that forces air in, and one in back that serves as a vacuum. When I put my hand behind one of the cubes, it feels like a hairdryer set on high, the heat is coming out so fast, and the heat NEVER builds , therefore I wont be killing dies anytime soon.

the class is 3/8" tempered glass from a desk and a dresser i got I looked it up...and you can get the same from http://elitecustomglass.com/ was gonna replace the desk glass
i used on the workbench but it was 82 bucks with shipping ..it can wait till the miner is a doorstop then back to the desk..on the other hand you could I guess plan to put
such on a dresser or desk you have now (pretty keen they are...desk calender under the glass an all on the desk) and just justify the price for that and under the miner for now..but
at that price the other dresser does not need the glass imho

the workbench i had set aside for the cistern area cleaned out (old house) for use as a small shop area with bench..but have pour a cement floor in that the floor slopes
and not even...so this will work fine for this..the price was only $199 usd which was pretty good .it is a great bench ..i used those wire closet shelves for the shelves underneath


http://www.samsclub.com/sams/ultra-heavy-duty-workbench/prod1490086.ip?navAction=


and tap and die threaded holes to hang the 220v euro surge protectors on the back ..I'd get these they have saved my ass twice from miner burn out..brown out city..
they come with a cord from the unit to the titan plug standard ..but you have to get a plug to the 220v outlet wall adapter of our choice this link

I can't recommend these enough....

on a side note around May 31st 2015 of so when it gets hot around here I will have to put in some attic gable fans with thermostat and shutters with plywood etc to cover windows above and open windows in bsmt to pull air thru.....should be fine...it is always like 10 degrees cooler in the basement then outside and the knc stuff seems to not have any problems with the heat ...upper midwest 100F outside would be 90f w/o the fans  with the fans I should be able to get this down to 80F and it will OK in the basement

but yeah that is a real butcherblock top on that worktable......was well worth the extra $50 bucks from the other junk workbenches i was looking at

heh not sure when it goes back to a workbench do  i really will need 3 220v separate individual circuits to the workbench thou heh

Oh yeah about 295 from the 4 cubes with 2 dead dies i guess. Thats not to bad, i don't think they guaranteed dies but only hashrate as you well know. Hurts tho dosn't it!? Knowing you could have two more dies running lol.
Stuff like that irks me bad if i let it.

I like the glass you have them on thats a nice idea and that bench they are on is pretty serious

prob as good as I'm gonna get I have 6 cubes on 2 corsair 1200i psu's with a dead die cube on each psu (of the 3 to a psu)

i get last I looked an hour or so ago 475.1mh (this is again with 2 dead dies on 2 cube out of these 6 cubes)

the other titan i got at a good deal 1 month ago I get 175.0 mh even (all the dies from this 2nd unit are golden)

so the total for 8 cubes across 3 psu's is 650.1mh..which is probably way more then I should even expect with 2 dead dies in the OFF position

I probably should/could play with the dead dies but the knc titans are such a piece of sh*t raspberry pi looks like a $49 buck science fair kit

just did not think the constant up/down restart was helping the lifetime of the crap.....and i sure was not getting anyplace to get the dires working

if i had any balls i'd take them apart and put new thermal paste on them etc...likely it is due to that imho being done sloppy or some have said as much
but then again they had 3 dies dead and had no real recourse but to try that...seems extreme with only 1 dead die on a cube each (total of 2 cubes and 2 dead dies)

but anyway 650.1mh looks pretty good with the dies on  the OFF position imho .. I sometimes feel i've tempted fate enough with these no roi no refund knc units

er to clarify above... i have 2 titan complete units 8 cubes....i put 3 cubes on a corsair 1200i each to save going out and getting a 4th psu seems to work fine
thus why I have it split like that ..the 2 cubes are solid on the 2nd controller thus the 175mh ...and both titans are 1st batch early units (nov 2013 or so) the
2nd was used got it a month ago and split things up in this arrangement
