Whats your current hashrate from one machine searing

the screenshot says there are 2 pool workers, wouldn't that imply 2 titans or 1 titan and another rig?

I've seen pools double count rigs in the avgs. For instance mine with rig.1 then switch names & mine with rig.2 and you'll briefly show 2 rigs running at twice the mh/s. It's just an avg as you're still paid only for shares submitted. The avg doesn't mean much if you are trying to game the system

Be that as it may, with a high share difficulty you can still get extreme swings in pool mh/s due to variance. I have seen swings over 1 gh/s with  really high share diff but they don't last long

unless they changed their minds...4 months ago (had the titan 5 months as of today) they would NOT RMA any unit not DOA on arrival and/or that as a full miner got over 300mh
or they would just send it back charging you for shipping both ways (got the email someplace will post if i find it) in that my original unit got 307.4mh at the time or some such even under the old crappy firmware of the day..i did not bother...also folk that had bad cubes the month ahead of me had already been waiting 1 month for RMA...so.the first units had burnt connector issues...and whole cubes dead etc ..some were put together wrong etc (now you know why knc forums got nuked)..knc was very pissed off I even asked....

perhaps things are different now...but it was to their advantage to send me that blanket statement email back in the day ..i kinda doubt they have had a change of heart by now

I also heard it was a min of $400 bucks to send a cube back...can anyone elaborate on that rumor? (insurance by knc on the way back...by shipping by whale? what?)

but feel free to point out their change of policy...my attempts were 4 months ago and also to add insult to injury the NOT WORKING as advertised did not apply back then to
dead dies IF you could limp your machine over 300mh..you could not RMA under any circumstances..ie lump it...........(if i remember the email...go to advance page set your settings to 325 if the titan gets over 300mh we will not accept the any cubes from the full unit as a RMA in that you got over our min of 300mh)

on a side note they had another brief email that titans sent back for refund or RMA with out an RMA number would be 'scrapped' that email was corrected in a day or two  or so from the uproar....also about the time they buckled and changed the 3 month warranty to a 12 month in that guys had not got back their broken titans and had already lost 1 1/2 months waiting....

so yeah ...so i was not very encouraged to try.....admittedly this was around 1st week of dec 2014 when i tried to push this
and lots of shit was being sent back as broke much worse then my stuff

anyway i suspect now that they are winding down i have missed any window where it makes sense to do this ...i doubt they have more then 2 techs if that on RMA stuff now..probably only one...it is how they roll now

They will RMA the two worst cubes from each set, God knows when you will get them back.


ohhhh i forgot its



My bad

shhhhhhh.....you were supposed to wait till he got my 2 dead dies working (hey at this point i will attempt the voodoo for dummies book) now you went and 'discouraged him" all to heck......

Sorry not possible.

The hashrate on the machine is the most accurate not a pool. I don't, of course, mean to burst your bubble. It is, however, going to happen at some stage in the near future.
Come and tell us how happy you are in 2 months when dies start dying and new firmwares actually hash at lower speeds, ect ect so on and so forth.

OK ..enlighten me on something more 'simple' then the above ..i have 1 dead die on 2 diff cubes...I messed around some but gave up and they are currently set to OFF

so shoot me some pointers

something like..

1) should I approach this from the 'bottom up' the lowest voltage I can put on a  die with the smallest setting in adv pages? ie work from the bottom up ...or should I
work from the top down with the lowest voltage i can set..ie work the asic the other way around...1 voltage setting below then set to 300mh etc in a downward manner
(which is how i approached it before and got no place)

2) can you undervolt and still get the 325 settings in adv page to work (thus saving a bit of elec?)

3) can you over set above 325 on adv page in some manner?


anyway interested in how you would approach this if a titan cube with 1 dead die arrived on your doorstep....how would u approach this to try to get the die back up?
(use small words i did buy from knc i obviously have issues...)

4) I've also heard of people taking the die apart....heatsink etc and putting new thermal paste on a complete re-do

anyway as i said i just did the attempt at voltage changes and speed changes from the top down...but would b nice to know what voltage is too high to try per setting
or what voltage is too low on going thru the steps...so again...how would you approach to revive 1 dead die on 1 cube..by the numbers please

if you can get 700mh I should with your help (and others on here) hopefully be able to get at least one of my 2 dies back into play

thanks

 

No you misunderstood, this is *1* Kncminer Titan Batch 2, running at 700mhs... Yes. Magical. Lol

Vegas

Magical?  I'm not sure If I understand this right, so just asking to be sure....
You got two 350Mh/s Titans to run at a combined rate of 701Mh/s... right?  
From the sounds of it.... the magic part was getting them to run at the advertised batch 1 hashrate?
I thought I heard somewhere the second batch Titans were supposed to run at 400Mh/s each? ... I must be staying up too late, lol.

Speaking of tweaking, Ive been tweaking this baby all day and now she is singing!! This is only 1 set of Titan Batch 2... and its magical!!!

Yes these should ONLY be sold to very technical people as they are a nighmare to get working, but when they do..hold on tight!

Nice, I'm running 3 cubes off 1 15A circuit and when I get my other PSU, I will run 2 off another 15A circuit. Does it matter if these circuits are shared? Also, is there any way to tell how much power I'm using right now? On the interface it says about 830 watts. Is that accurate?

I'm running 6 on a converted dryer 220 circuit. And the others on 220v at the office.  I had them install me 3 new 30 amp circuits for my mining.

6 cubes no problem . 5 cubes also no problem.
just dont use the standard -0.0366 but tweak per die ,, same go as low as -0.0824 or even lower
But its very impotant you have a gold , plantinum or titanium power supply.
and make sure your power grid at home can handle about ~ 6000 watts that´s about 26 AMP if 230 and 52 if on 115v !
if you have 3 phase (europe) and 3x25 amp main fuse you can spread the miners over the 3 phases.
so each phase gets about 8.6 amps if on 230v , assuming 2000 watts.


 

Exactly the only mistake KNC made was assuming that all of us are cutting edge hackers and developers.
I got to neotunes running full speed taking between 1800-1900 watt at 3.6THash
when I would suggest that KNC only sells to people who can proof they can handle a miner.
If they cant they can not buy it.
all complains are made by people that are not having fun by tweaking the max out of a cutting edge chip.
 

That's cool. I was hoping to get close to 3.5 but I guess maybe I'll have to purchase another miner. Are you running 15 cubes at home?

I'm running 2 titans and I get out of the 8 cubes 650.1mh and I have 2 dead dies ....one each on 2 cubes.....completely set to OFF....and probably
am damn lucky to pull this off ...just a an example

gave up on getting my 2 dead dies to work ..probably should yo/yo the unit and experiment...but they made such crappy equipment....dorking with
it anymore makes me nervous as hell ...especially up/down with shutdown....and again probably lucky to get the 650.1mh

anyway for your info and guidline

Wtb one knc Titan
Pm me

I doubt you can.  I've got 6 cubes running stable at 4Th, but out of 15 cubes, only 3-5 run full on without too much heat.

Yes, sorry, I meant in total. I only have 3 plugged in right now because I don't have enough PSUs. I have a OCZ ZX 1250W and a Thermaltake Smart 750W but I'm only using the 1250W right now because I'm worried the Termaltake's wires are too small for a Neptune? Not sure. Anyways, how could I get 3.5 TH/s even with 5 cubes if I can't push all the miners to 500MHZ?

3 neptune cubes cannot reach 3.4 terrahash... you're missing 2 cubes for that.  5 cubes you should have.
