If I'm not mistaken, that VRM PDF you linked is not the right one. That 50A unit was used in the Neptune only. KNC cheaped out even more by using a 40A unit in the Titan.

In that case, ours is on page 9 =) ... very close to the same.

Ok, here is my updated formula:
PER DCDC its doing this calculation: P * 1.15 + 5    (Measured power , 85% eff, add 5w for DCDC power dissipation)
Which comes out to about 330w per cube. (on my titan)

Then for wall watts its:

Cube power * 1.15 + 5 + 25 (Total cube power as per each DCDC added together from above equation, 85% eff PSU, add 5w for pi, add 25w for controller board)

Gives my total wall watts of 1530w, which is EXTREMELY close to my measured 1515W at wall.

I dont really know how much the controller board consumes, so thats a pure guess LOL!

If I run the SAME guestimate through ur 5 cubes and ur 94% PSU, it comes out at ..... 1779W!! Which is also very close.

What ya think?

The only thing I cannot account for is all the different effeciency levels of the DCDC, so if someone is running the DCDC at like 90% eff, my calcs would still assume 85% =P

In regards to custom effeciency setting, I was thinking, for sake of cleanliness I would just add it as another setting under the SYSTEM tab, thoughts?

That sounds much much better! I just got home so I'll get the measurements soon for ya, along with a screen shot of the advanced page for all cubes.

The only way someone could get to 90% DCDC efficiency is if the underclock the cubes, right? Doubt anyone is doing that. I wouldn't worry about it too much if I were you. What's more important is getting the proper reading for normal use cases.

Here ya go, Tarkin:



I can't get a reading on the 5th cube for now as it's temporarily running on a Seasonic ATX PSU. I can't get my clamp on the 12V wires since it's sleeved.

Would you also like a reading of a cube running 325MHz at default voltage, (-0.0366v) or is that unnecessary?

Looks like my calcs are spot on!
Except for that first cube, Im gonna assume the increase in power on that cube is because of the DCDC's running in the 42+ AMP range... man effeciency must PLUMMET drastically beyond the 41 AMP range!

I must say, Its fucking crazy that *everyones* PCIe connectors arent melting ALL THE TIME! Thats 27.5A ... thats way above the 23A rating, its even above the good ol "10% specs deviation rule for electronics" which in this case is 25.3A
~ only if we could make 14V go through the PCIe connectors instead =P ... would take a decent amount of load off them and probably make the DCDC's work a tad more effeciently. LOL!

Fun times!

Any way you can measure the power leads going to the controller board from PSU?(if thats how its powered)

Yep. Shame that KNC didn't spend an extra $10 per cube to put the 50A VRMs and a second PCI-e connector.  Undecided

Just measured the controller for ya. It's using 2.25w on the 5V rail, and nothing on the 12V rail. That's with 5 cubes connected and the LCD screen. I'm surprised by how low that is!

Yeah, really really low. Guess the CPU isn't getting much of a work out!

That's 0.45A * 5V = 2.25W  Grin

I wonder where the scryp midstate n crap is calculated ... on the controller board? if so then that power usage will spike up a tad when a new block is found or a work restart.

Ok, well I just finished up coding it all, now theres an additional section in the SYSTEM page that allows you to specify PSU effeciency, ranges from 50-100%
It will update the % on the advanced page whenever its changed.
It defaults to 85% if not specified prior(ie: before upgrading to new version)

These updates will be in next release =)

As posted above: PER DCDC its doing this calculation: P * 1.15 + 5    (Measured power , 85% eff, add 5w for DCDC power dissipation)

It will  add all 8 of the DCDC's power as guestimated by above formula to show the cube consumption.

Thats the new cube formula, so its still an estimate, but its a lot closer to actual cube power consumption.

So, time for me to post an RMA experience with KNC. They were absolutely fantastic. I seriously could not have had better service. I almost feel bad for ripping them off in the process! (almost)

I've had my Titan up and running since October 6th of 2014. All dies were working initially, but a die crapped out 2 days later. A week later, a second die down. 2 weeks after that a third. 2 dies on one cube, and 1 die on an other. KNC only agreed to replace the cube with 2 dead dies, which pissed me off to the extreme after having paid $10000+ for the miner. I set up an RMA for the cube, but never followed through out of fear of the probably horrible service I would receive from KNC. Fast forward 10 months, and I now had a 5 cube Titan. I bought a cube with 2 working dies on this forum, but it turns out only 1 die worked when I received it.  Angry

Fast forward a bit more to the end of September when I realize that I have to act now, or my warranty will be expired in early October. Get back in touch with Kurt @ KNC via email, explain (lie) that my 1 dead die cube is now down to 2 dead dies, and my 2 dead die cube is now down to 3 dead dies (really this is the cube I bought on this forum). Kurt promptly issues an RMA number and has me send both cubes back to KNC. $200 and 4 days later, my cubes arrive in Sweden on a Wednesday. Kurt informs me that they can't repair the cubes and that they've been replaced with new ones. They're shipped back out to me 2 days later on Friday, and get here early the following week. They've been hashing perfectly for the past 3 days, and I'm a happy camper.
 


Not sure if you really ripped them off. At one time if I remember correctly they 'claimed' that the warranty follows the device..if that is correct it was probably 'safer' to mention it in the manner you did (hey they may have just been saying that) but on knc forums (now down) I seem to remember them saying that (of course they said a lot of stuff before the titans shipped on knc forums)

but still ....myself if I ever had the same situation as you ....I would do it in your manner...nice to know you had some 'good luck' ...... BUT maybe they are keeping their word

(I know it is unlikely..but then again you got quick fast RMA service from KNC so perhaps the age of miracles are upon us!)

Anyone else remember the same claim from knc forums ...that the warranty follows the device? Anyway what I think I remember for what it is worth

Again good for you...a win!

I'm out running errands right now, I'll get you the measurements in a few hours.  Smiley

AWESOME!

and you know what, I just figured out!!!! NO WONDER peoples PCIe cables get fried left and right on thse things.
Now that weve exposed cube power consumption is much closer to 300w ... its a no brainer! The poor lil PCIe 6pin power connector, as per molex's website can deliver up to 275w safely @ 12v .... these poor things are running on the verge of meltdown 24/7 essentially! LOL
Not to mention we already run the DCDC's beyond spec of their current deliver capabilities!  LOL!

Im sure glad I never figured out how to OC beyond 325mhz ... peoples cubes would be melting left and right!


FU KNC for being a bunch of cheap bastards! shoulda went w/ an 8pin connector or maybe even 2x 6pin per cube! ...


NOTE: Rant Below! Title of Rant: "How to be the best evil asic genius type of company you can!" You don't like my rants put me on /ignore I don't mind Smiley



Yeah again from what I understand following the old KNC forums (others correct me if this is incorrect) is the following:

The original Titan was 250mh but due to delays they then upped it to 300mh (standard) it was only AFTER they had the bad die issues etc that they told folk
it was OK to run them at 325mh or over clock them in my case in KNC forums PM with tech staff 1 month after I got my Nov 6th unit more or less.

....so due to late delivery imho and the fact they were 'designed' again imho with an over capacity
at 250mh.....well......the initial push to 300mh was do'able ......they could up the speed a bit and toot their own horn as a result in that it was 'overbuilt' on the
original 250mh speed....then they got stuck with bad product design and no slack in the setup when they pushed it beyond that point when they had bad die
issues and other problems with the Titans....a step to far so to speak Smiley

But with problems with 1 batch dies and such out of the gate for the Titans...they then upped that an'ti again and made the (in reality) the previous OVERCLOCKED setting of 325mh
the standard settings on the dies was an act of desperation to make up for the lateness of the delivery..... by touting the increase in speed....and the crappy construction
of the 1st batch units especially (late) and the first couple months....they of course had to push it as far as possible to play 'catch up"

To top it all off...knc probably figured it was no big deal to do so also from an RMA point of view.

They originally claimed (a change from 1 year not touted) that TitansONLY had a 90 day warranty...so this would have worked well on them not having RMA issues and the customers being stuck...but they neglected to change their warranty info on their web page for a month (still said 1 year) and of course the firestorm of the 1st batch titan units being crappy out of the gate ..they backtracked and made the warranty 1 year again. Said it was from the kindness of their hearts was really because of all the first batch units ordered that first month they had prob 1/2 90 day warranty and 1/2 1 year..so they made everyone 1 year..but again it was from the mistake on the web page on ordering and people had proof so they were kinda stuck.

I always keep in mind these raspberry pi piece of crap 8th grade science project units ...were 'designed' to only last 90 days or a bit more.....The fact my Titan(s) both
Nov 2014 units probably will go beyond 1 year in 2 weeks is a frigging asic miracle imho (you have to take what you can get from all this positive wise)

So to sum it up there was no slack left in the Titan setup was kicked up from 250 to 300mh .....then in desperation due to all the crap i mention here with the problems they had with the first batc... to the max of 350mh...so it was a big change in policy.....ie run the baby full out over clocked from day one and let crap burn out as it may..if you got over 300mh on your hacked together overclocked unit ....no RMA if only 1 bad die per cube ..your prob still over 300mh (in my case 306.1 with 1 dead die each of 2 cubes) you are out of luck too

I know for a while they would NOT RMA when you burnt out your cube for not using a Y adapter or other issues..they MAY have changed that but I remember a lot of angst
in KNC forums on KNC saying it was a PSU issue etc on your end

It is a frigging miracle the PSU plugs for power on the cubes don't  burn out once a week in that they made standard settings/speed imho for 250mh unit and now it is  100mh more then they designed the units for at 250mh (with probably the proper 'over build' of components at that setting vs the totally 'inadequate' way they were move up to)  for KNC  to cover their ass...and paper over the crap they were pushing. (don't get me started on the first couple months where the firmware sucked a whole nother rant!)

When I got original Titan Nov 6th 2014... this 325mh setting was NOT the norm..... I was only informed of this when 2 dies on 2 different cubes died then I was told this was OK to do by knc techs via knc forum email)..so was not the norm for me .....but due to again the above issues they had with the 1st batch it became the norm......

It also worked out for KNC in that when i tried to get an RMA for 1 dead die on each of 2 cubes they said I still got over 300mh so they would NOT RMA (probably
due to the swamp or RMA's for the issues I've stated above) but that was based on the overclocking of the other cubes to the 325mh setting on advance page..so they
scam'd their way out of doing RMA's on what should have been the standard speed of 300mh by the customers eating the problem and attempting to burn out the
power connectors and other issues.....evil asic geniuses they are indeed!

In my case being told after having the unit a month it was OK to over clock my 300mh settings to on adv page on the Tiitan (then gee guess what I had 2 dies 1 on each cube go dead) then being told by KNC that I should overclock for dead dies the other dies at 325mh ....so I did..it worked...but then I said I want to RMA my cubes... they say we don't RMA cubes with only 1 dead die each and you said you get 306.1mh with your 2 dies set to Off anyway...nor do we do so for any Titans getting over 300mh ...no RMA's (if I would have had 3 dies dead on 3 cubes then as it would be under 300mh then I'd get them RMA'd etc)


So talk about having your cake and eat it too......they tell you to overclock the titans to 325mh settings from their own standard of 300mh and barely designed yet to do and they flake or burn out connectors on your psu cable connector or your cube connector etc or what happens in my case maybe the dies? or you have legit RMA issues at 300mh with 2 dead dies on 2 cubes and then they revise the rules on what is standard (no longer 300mh now 325mh overclocking)or not to tweak the warranty and rma stuff in their favor. Pretty slick way to dodge any real reasponsiblity imho.


Last point in this rant ..they initially said you did NOT have to use Y adapters for your PSU's either .. 300mh on adv page was before they shipped ..just 16 awg wire on PSU's.
after folk started blowing the power couplings up..they then said they recommended such and finally said they would come with your titan....I got 3rd party Y adapters for the psu
before even turning it on.....I got the Y adapters from KNC laying around here that arrived 3-4 months later if I remember correctly....man they really really did not give a damn about customers my guess is they knew at that point (pumping Neptunes in their farm) that we were the end of the home miner consumer chain and they could do as they damn well
pleased I guess...they are their only customer now with the 16nm chip and their newest data hall

well played knc well played (they really do have this whole 'evil genius' thing down don't ya know!) Smiley

on a side note  the only evil genius flubs that KNC has done imho is 1) why did they keep knc forums up as long as they can before pulling the plug? (I sure wish I would have archived it) and 2) why the hell have they not 'locked' this thread up yet? Other then that ....everything else pretty much seems to have gone their way ..being evil works well I guess Smiley

Its the name of the game man! You have people willing to line up and shell out big bucks for shitty products ... any company will take advantage of that and lead their customers to the slaughter. Just look at apple.

Its the name of the game man! You have people willing to line up and shell out big bucks for shitty products ... any company will take advantage of that and lead their customers to the slaughter. Just look at apple.

Yep...I was that 'newbie sheep' as you say ...(I was such a great and happy newbie in 2013 after drinking the kool aid thou) Smiley

Now I'm no longer a 'bright eyed newbie" (but with dreams of $1000 usd BTC again someday....I could go back to stupid newbie mode..in a heartbeat!)

Live and learn I guess at least I was well enough out of my 'newbie year" by 2014 I did NOT get sucked into the 'cloudhashing scam" /paycoin scam /
had NO $$$ in mt. Gox/ and whatever pre-order probs I had with BFL and Alpha Tech (still no scrypt miner 2 years now) I got refunds due to 'dumb luck'

Used up my 9 lives of luck with crypto like a cat on the freeway.

So after these Titans go to doorstops I will be into 'attic mining' ..in my case I look at the 5k of crap in my attic..sell it on Ebay and then buy crypto with it!

So then coinbase is my new flame at that point (oh baby hubba hubba)

No more 'Hot Mess' full of Drama "Mining Relationships" ..sure it is great like Sex
with a crazy chick when it works..but mostly it ends up badly and you feel dirty after....or in my case 'survivor's guilt from a BFL refund one of the few) Smiley

hah! yeahp, I know how ya feel! There is literally no hardware Im interested in anymore at this point. Its all a fucking ripoff right now. The reward/risk ratio just aint favorable enough anymore.
It will be if the price ever returns astronomically high. But thats going to take a lifetime at this point LOL!
The titan was the last piece of hardware I bought. Glad I did cuz I learned a lot coding to improve it, so its been one hell of a fun project, no other miner has given me such opportunity. But, beyond Titan, theres really nothing left LOL!

Oh ... how I miss the GPU days! =(
When mining was actually fair and fun and decentralized.

On a side note I posted this a bit further back. The below video shows a guy tearing apart a Titan cube. It is all in Swedish but I get the gist of it.

Except for the fact of learning my cubes are 'filthy' after watching this video by peaking inside and probably I SHOULD ASAP use the Air Compressor
and blow out 11 1/2 months of dust in them (in basement ..cooling in summer as a big shuttle fan and windows open....my pics here if you want to see setup
lostgonzo.imgur.com)

Would it make any sense for me to put new paste on the cubes as seen in the video after I dust them out (probably would do the heatsink mod too as they are cute or
maybe I really should replace the paste...the Titans have been running 24/7 for 11 1/2 months. Maybe this stuff dries out or something?

Or would that likely NOT make any difference on my 2 cubes with 1 dead die each? Thermal paste just helps heat...the dies I have set to OFF would likely not
benefit from this at all anyway......

Newbie other issue....if I could or being a newbie 'likely too" use too much thermal paste or muck it up in many different
newbie ways ...on your advice ... I may just limit myself to dusting them out...

Then again it don't look TOO hard even from my limited perspective ...newbie that I am on such electronic mods

here is the video

https://www.youtube.com/watch?v=O-RBI4am-wY

One last point ....as I watch the above video ..I can see where taking off the 2 ends on the heat sink to get access to the ends for individual heat sinks, but why did he
not just also prune the front of the large standard plate heatsink also and put copper individual heatsinks on all of them?

Seems to me he still had enough of the large standard heatsink plate to connect the fan/cooler back down with the
thermal paste on the Titan Cube and just put individual heatsinks on all the components. (whole thing still looks newbie scary to me)

Vegas if you are on .....you can jump on this too on what you think of the process on the above video..you probably have better ideas anyway Smiley

Anyway appreciate the advice. I SHOULD probably refrain myself for 20 days till warranty wears out. Original Titan will be 1 year on Nov 6rh 2015.
The 2nd used Titan I got is also a Nov 2014 unit.  Then after that point in time I can drag the HACKSAW wave it at the
Titans and make evil laugh sounds at them...heh......it will be very very therapeutic indeed! Again should you think I should bother with the mods he does.

Again thanks for any advice.

That was a good video, Ive been wondering how the inside of the titan was put together =P ... I dont have one physically, mines hosted(yes all the coding Ive done has been remote) LOL!
He put WAY TOO MUCH paste back on the ASIC, it will be oozing out the sides if it seats properly. I prefer to have a much thinner layer when I apply paste. Hell, I dont even spread it out, I just put a tiny bead in the middle, enough pressure should spread it out evenly as needed. Thats how arctic silver has always recommended application of their products.

I guess getting ambient temperatures of measuring points of the DCDC's are pointless now, it was something I askd vegasguy to check on while it was mining, but I didnt realize they had a "heatsink" on top of them for cooling =P
Yeah, I would like to see the temperature deltas between the banks he applied the copper heatsink on vs the ones he just left w/ the alum "heatsink" ... if the temps are anywhere near close then individually sinking the DCDC's is pointless. But, I know vegas has done a ton of work on tweaking the cooling on these things so Im interested to see what hes got goin on =P
Heck if that metal plate gets really freaking hot to the touch, that means the pads are doing a great job of transferring the heat to that plate from the DCDC's ... which means if u put heatsinks on the plate, even that would help cool those DCDC's better.
Hes still making the video lol!

I don't think you can get enough pressure to use the bead in the middle technique because the board flexes. Also you need to fill the gaps in the copper pipes on the heatsink, so need to spread it on both surfaces ... if you don't you are just going to have to take it apart and do it over, at least that's what I found, and I've had all my cubes apart. It's a pain in the neck doing it twice because you didn't put enough on the first time, and when you take apart again you can see where the paste didn't spread right
