Here is a good calculator

https://www.litecoinpool.org/calc

The controller doesn't share a common ground with any of the cubes correct? So you are allowed to plug them into different breakers?

Someone on here was aksing about this...it is JUST the knc old site (not the forums) but has all the news
and patches from oct jupiters etc on

just figured it may be useful to some

i'm currently using httrack websidte copier to grab the stuff and firmware..but again forums is down

here is the IP to try

http://168.63.65.32/


just pop that in and let it run...again forums come up as 502 error

looking at tools to merge all the knc forums wayback machine archives into one archive to see if we could get a more complete mirror of the forums

i see tools for such but looks over my head

that would be my suggestion to the more knowledgeable then myself if there was some way to grab all the 'wayback machine' archives and 'merge'

them in some manner to recover

www.forums.kncforums.com ..using that or IP or whatever

but again all are on below

https://web.archive.org/web/*/http://forum.kncminer.com/forum/

well anyway was just a thought..but anyway for those in need or want to track firmware progress etc for jupiter 2013 and onward use the above ip

but again would be nice to see all the wayback forums (if possible) merged into at least a 'half-assed' version of forums tech info

would be helpful

anyway for what it is worth at this late date

by the by

www.kncminer.com

still has pages up for neptune and titan stuff fyi....

Very happy with Noctua NF-A14, a tad louder than stock fan but cools much better.

They managed to keep temp below 80F during summer months, but I also added individual heat sinks to the DCDC module (like in Swedish video). Temp would go up to 90 when I was using stock fan.

Hey I have a seasonic 1200i that has worked well since nov 2014 on my 6 cube Titan setup

summer it toggled itself off...so i put 2 cubes with 1 dead die each and reg working full cube on it to save (100 watts)

it did this on me again less then 1 month ago

and it was fine up to this week...now it has 're-lighted 2x time in 3 days"

so my post here on such..in that the 'asic gods' are trying to tell me something i fear (like get another corsair 1200i you cheapskate!)



so my question is I have a 660w corsair (remember knc in 2013 saying they were gonna have 3rd batch and then did not yeah still new lol)

anyway I COULD make this 6 port unit with 3 cubes (fading corsair 1200i) into a 5 cube unit and move the cube to my other controller using above seasonic 660w
so that my 2 cube titan unit (works fine with 860w seasonic) into a 2 psu unit and 3 cube unit

that is my cheap ass plan (unless folk think it is too dangerous from what they see my psu doing..thus this post to other titan types)


BUT is this a 'sign from the asic gods' that the PSU is going BAD big time and I should just replace it?

(the self test comes up ok go figure)

temp in basement is like 64F so THAT should not be an issue..also have euro 220v tripp lite surge protector on the unit...and the other corsair on same controller
works just 'dandy' ..that one has the controller power as well...so the 'fading 1200i goes and poof' she mines at 1/2 speed ....

(as i sit here looking from work at my 429mh vs my usual 645mh ...gee a whole 2 bucks a day I'm losing after electric! (the horror) with LTC anyway

anyway if worse comes to worse the only problem with my 'cheap ass plan' is even running 2 cubes it 'fades out and off" and it won't be stable ...I will try this

would be slick if I could at least 'see' if this could limp along with 2 cubes only.....save me 309 bucks (or at least alllow me to get a new corsair 1200i and keep in the box

as a spare ...if I go full coward)

if folk on here have more experience with this then myself and say NO DON'T it is a sign of something worse and could fry the titan etc would appreciate the 'heads up"

....but anyway just wondering what folk think

also have the old 7 year parts and labor warranty on this corsair 1200i i psu's is the postage/costs worth looking into to get such refurbished? (309 sale w/ship on newegg as an example
of new corsair 1200i costs incl shipping)...has anyone every 'refurb'd' a psu on such a plan after the 30 day replacement has passed...is it worth it?...

anyway appreciate it ....don't need to turn the 1 titan into a 'doorstop' quite yet if the consensus is my PSU is shot as hell and just letting me know before it 'blows up"


(i bet we will see more of these posts...actually like 14 months 24/7 probably is NOT unexpected to replace a PSU on these....but still)

anyway 'expert' advice from others 'maybe' with similar issues (gpu/asic/or other) please reply with advice

thanks



Did you get a picture of your 'obviously' modified cut down 'heat sink plate' on the above also (or a link)

trying to 'man up' and do the same

on a side note I 'heard' from someone who got an email from kurt at knc (tech) back in the day ..that you put the 'thermal paste' on the 'heatsink' not the chip..just enough to cover it

not sure if legit advice or not (it is a knc tech) but figured I'd pass it along here .....perhaps we can have a debate on the merits of each

anyway my plan is if I ever do such I will simply take the 'heatsink plate' to a local metal shop ..give the guy 10 bucks to cut it 'precisely' and buff it up...lazy that I am

anyway again a picture of your mod would be great!

Do you mean 80C? ... so basically a 10C decrease using copper & improved fan?
If you meant 80F ... then I meant ... how much did the DCDC temps change as shown in the webgui =) .. cuz those numbers are in C

In stock confugration .. the stock plate just touches the tops(the inductor - where u put copper hs) of those DCDC's right?

That is a really, really smart idea. Covering those inductors was one of the more brainless things I have seen.

Mrph. Most of the heat can actually be felt *under* the board which is the wrong place for it to be.

I haven't actually gotten a temp probe to play, but in almost all cases the real source of heat is not the inductor it's the high side FETs. And those get no air on the 1/2,3/4 supplies. And those are what is right next to the caps that usually blow sky high....

yeah thanks glad i tripped over the knc ip address again

wondering if you  or others know...or have better google skills then me

but i go to

Internet Archive: Wayback Machine

and there is a crap load of 'saved site' stuff from KNC ..i'm unsure of "how deep" this goes (ie all the way down like 7 layers or more to forums)

BUT

There HAS to be a way ..you can get all these daily 'snapshots' and 'merge them in some manner ...getting out the duplicate links

and maybe just maybe 'merge' the archives into some kinda workable (kinda sorta) mirror for knc forums?


It would not be 'ideal' but better then nothing..er maybe?

anyway I looked at it ..no zip about comp sci stuff like this ....maybe you 'd have better luck or can ask around too as well as others here

so far no luck way over my head

other then that still doing the WinHTTrack program for archiving  the IP address anyway
...it takes a bit to grab it all in an archive

anyway what i'm thinking ..perhaps it is NOT possible ..i'd think such could be done thou

anyway tossing it out there for the more skilled then myself (there should be more then a few lol )

here is the IP address (w/o forums) link again

http://168.63.65.32/


and below is the part of that page above (forums) which does NOT work. Thus my merge of wayback machines archive above (er maybe?)
