Anyway, just an aside for the thread.....serves them right thou Smiley
As another aside I got one of the very first titan's, and pointed it at litecoinpool.org, and I was ranked at #3 on the pool

Now down to #7510  Grin

I got up to #12 at one time...I just make a BIT more money (even with the hassle) on www.prohashing.com

so like the 'gold digger, I am" I left pooler at www.litecoinpool.org the pool is still as backup pool, and went for the $$$....

(I'm such an ASIC slut...sigh)


You got to admit though, they made some pretty good hardware with the Titan. The fact that it's still profitable is quite frankly amazing....


yep, at over now with repastings $100 bucks plus per cube....and gen tarkin software and mods etc below.

1) new fan  per cube ..tossed old one in a box

2) knc heatsink same ...tossed old one in a box

3) replaced fan with 2x the speed at 120% the noise

4) replaced knc heatsink for Maxumark's bracket set that frees the dc/dc's to the airflow

5) got dc/dc copper heatsinks for above 8 heatsinks

6) with the high-speed fan etc and airflow, it is best to clean the boards with alcohol and repaste every 6 months would be ideal
    also use better thermal paste (not as much)..and viola

7) you need Gen Tarkin's 3rd party firmware product that does things I have on record as knc saying was impossible, temp shutdown fan shutdown
    chip speed adjustments downward for heat...the list goes on and on

Cool I and Maxumark use dual 1280 platinum (new) server PSU's with factory backplate to slide into (with the PSU guts like a regular PSU for voltage protection etc) and
instead of 16 AWG wire and using knc y adapters....use 15 AWG wire and direct plug into the cube...no y adapter weak link...they still brown out eventually but that
may take more than 1 year. We run them as pairs of 2,560 watts and 5 leads.....not an issue .no burn out problems..no PSU problems more than 14 months plus?

9) on probably 3rd if not 4th repaste for all cubes (with cleaning)

10) when/if eventually a plug on the cube does fry and melt plastic..lightfoot hates that I say this..but have had no issues on the 1/2 dozen or so units I run using
     just the 15 AWG bare plug slide into the pins ..make sure the tab is up...now this MAY be because it is 15awg wire ask lightfoot..that I have no issues..

11) the damn things are just too 'evil' to die...not sure what kinda Swedish voodoo they did to keep them working this long...but pretty sure baby ASIC's were
sacrificed in some manner.....

so yeah, amazing they still work....but jeez.. quite the chore!

so yeah, amazing they still work....but jeez.. quite the chore!
Big warning here: If you ever plug the cube in so that the bottom three pins on the PCIe plug go into the top three pins on the socket, or put it in upside-down, the following will happen instantly:

1) The cube will be damaged, all drivers blown.
2) The ribbon cable will burn.
3) The controller will be damaged, needs new FPGA and power chip.
4) Every other cube on that controller will be permanently destroyed with no ability to repair.

Doing the above puts +12 on the ground plane which destroys the hashing chips pretty much instantly. I have seen this happen several times with people, whole miner is gone.

So if you're running on burned connectors always check every plug before powering on. One mistake does it.

yep..nice little tab up on my modified 15 awg wires....but hey it has to be better then replacing KNC Y adapters every 6 months as they blew (really, it was that often

I kid they not) no blown y connectors even on the ones I use to keep the now bare pin cubes working

again 15awg wire seems to help along with no crummy Y adapter in the loop to burn out either


but yeah, you have to check this....I suppose I could put some paint on the tab just to be double sure in the future

KNC used cheap PCIe sockets on their boards. Switching to all nickel plugs makes a fairly nice difference on the burn rate.

Typical build a thousand dollar cube and save a dime by using a cheap component.....

Yeah, well paying you to solder the proper plugs back in ...or just using the bare pin with the knc Y adapter hack..I went with the hack (then again LTC for all 6 of them

until my most recent one this month was probably 4.15 per LTC ..so it made sense then I guess the above ugly hacks previous to the LTC price pumps)

so anyway..in my case ..likely with the stable platinum server PSU's dual 1260 each or 2520 or so watts if I remember right at 96% eff) along with

the 15 AWG wire and heavy duty plug on the PSU end you feel prudent....I'm just gonna continue with the bare pin mods...but the 15 AWG wire over kill is likely the

part that has allowed them not to go toaster city...in my case anyway...again I think I have at least 6 with this mod..have a buddy with a lot more than that...at

his data hall...none have fried again after this mod and the full Maxumark brackets/gen tarkin firmware/15 AWG wire/better fan/ heatsinks on dc/dc's etc etc etc)

so anyway, what I do (or did) I suppose if anyone out there is reading this with a plug fried...if you got to send it in to lightfoot get a price on the plug replace

on the cube...but again mine burnt..pin hack...and worked after...so no need to send them in....but it is of course as lightfoot says 'at your own risk'



KNC devices being evil and all...MUST DIE SOMEDAY....being purely evil and all thus Lightfoot acts as the devil's advocate and keeps FIXING THEM

and of course...then they don't die..rinse/wash/repeat...as lightfoot yells 'live my creations' on each cube revived.....(evil lair there, let me tell you!)

so I got to draw the line someplace to allow them to brick themselves or we are all lost.....(frigging skynet...the beginning of skynet, I just know it.....)

Can too much cooling affect the cores on the Neptune miner?

It's winter here in Canada now, its about -20 outside. I have my basement window open in the room where my Neptune is running, a few of my cores have stopped working since it got colder.

Here is my miner status RIGHT now.


Here is what Advanced core info shows Right now.

I wonder if you could boost up the voltage, I mean hell they aren't overheating :-)

And how are you keeping from melting the plugs. 220w/cube is heavy load with Titans, you're pulling 300 (it's more than 300)

I bought special cables off here. They are thicker gauge wires.

Those are special cables all right.... Sandoz Laboratories probably makes those cables :-) Do they go all the way to a modular power supply?

The ones I have do, they are thicker wire and better plugs at both ends, you just specify what PSU when ordering, I got mine from Shakmods as soon as it became apparent how much power the titan (or was it my neptune can't remember) was putting through a single lead.

Touch wood, not had any of mine burn and been running at 325mhz since day 1, maybe just lucky or the fact it's an air conditioned room, but certainly glad I got them.

Mine I think are Shakmods too. I just remember the guy who was selling them was selling them in metric and I accidentally bought the shorter ones which work.

Uhmm all I can tell you is I had to tell the guy where I bought mine from which PSU they were plugging into as the modular connectors to the PSU aren't always the same.

I use two EVA SuperNova 1500's at home.

Hello,

I know it's not worth but want to know how too program the beagle one black that is used on a KnCminer Saturn.

Can someone explain how I can update bfg/cgminer to the latest version? I tryd opgeh update and upgrade but nothing happens.

I upgrade the KnCminer firmware too 1.0.1 custom but this used also cgminer 3.8.0....

I hope someone can help me.

Hate to say it, but why? The Saturn will not benefit from more modern code in any way.

You could stick an 8-16gb SD card into it and run the latest BBB software or run the controller with a Neptune or Titan, but there's not much to do with Saturn code at this point.

From -ck's post about the rules of the Mining sections:

2. This section is for BITCOIN MINING and related discussion ONLY. All bitcoin forks and alternate cryptocurrencies and discussion of them should be directed to a dedicated forum for those, or one of the altcoin subforums on this forum. All discussion regarding them will be moved without warning to the altcoin sections. If your topic is related to multiple currencies, then unless it is primarily about bitcoin it will be moved. Even if it is about sha256d mining but not about bitcoin it will be moved. BITCOIN mining is done today ONLY with ASICs, and any discussion of mining with CPU, GPU or FPGAs will be moved to the altcoin mining section.

Any altcoin-related posts after this will therefore be deleted without notice.

Once again it would probably be better to move this thread to the altcoins so it can continue to have the full history in place. Splitting threads is a bad idea.

KncMiner had only one altcoin miner, and it was during the later part of their existence. It would therefore not make sense to move the entire thread to Mining (Altcoins).

The full history would still be in place. I'm not talking about trashing the entire thread and starting two new ones from scratch. What I'm saying is to keep all future discussions in this thread strictly Bitcoin-related, and that all future altcoin-related posts should be in a new thread in Mining (Altcoins).

The new thread in Mining (Altcoins) could begin with a link to this thread for the sake of continuity.
