Thank you, to the various posters within this thread. I think i've managed to squeeze:

Oct Saturn: from 280GH/s -> 320GH/s
Nov Jupiter: from 660GH/s -> 700GH/s

Admittedly only for a few hours. But temps, draw etc are looking quite stable.

I've seen a number of people bash others for asking simple questions. Reading the entirety of this thread takes time! A lot of time (be honest, there is a lot within). I just want to throw it out there that bashing people for not reading a +30page thread (30x20 = 600 replies) is a little eager.

Suggestion: we move the OC of KnC devices onto a wiki style page, thereby the information can be easily updated, and formed into a readable form. (Unlike ~600 fragments that we all need to interpret and join together each time a new person reads?)

//rant// (Don't even get me started on the failings of people to understand what vi is, and how to use it. They don't deserve the wiki page... (If you don't understand bash, then you shouldn't be logged into a *nix machine... Let alone be allowed to use vi. Or attempt to OC hardware that you don't fully understand)) //end rant//

Edit: (Maybe I was a little OTT with my rant, but if you read some advice from someone, they tell you to use vi (or any tool), and then when you don't get it you don't do any research yourself, just ask again in the forum/post, then that's lazy.)

Nighty Night Don't Let The Trolls Bite Nom Nom Nom

Ok I helped all you guys out, see if you can assist.

I just added a 4th module to make a Jupiter and of course with my luck it has a Dead Die 0

I am overclocked to 231

As soon as I try 241 or 251 dies start getting shut down due to HW errors.

As you can see I have the temperature covered.

Whats your suggestion on settings? What should I adjust in advanced?

This is a October Saturn/Jupiter with 4 VRMs

Thanks for any suggestions


Have you not tried increasing the voltage just on that die? Works for me

Yes it does not respond sadly

Have you tried to INCREASE the temperatures?

edit: this is how i would go about reviving a dead DIE, just watch, once it kicks in temps can increase quite fast in my experience and cooling them to the levels you are at just now will just kill it again.

all my DIE 1 which have been dead are revived by changing to 3.3 spi volt, but this will kill the others until the reach a certain temperature

Can we put as settings 221 or only 231 211?Huh

Yes you can.. I don't have easy access to the post but a number if times earlier in the thread a table with a more comprehensive list of numbers with associated clock rates was published. Last one was perhaps 2-4 pages back.

The list again Smiley


First column is speed in MHz per CORE
Second or third column is setting used for speed in column 1

Code:
700.0   1B1     372 
712.5           382
725.0   1C1     392
737.5           3A2
750.0   1D1     3B2 << stock Oct speed
762.5           3C2
775.0   1E1     3D2
787.5           3E2
800.0   1F1     3F2 < first example below
812.5           402 < second example below
825.0   201     412
837.5           422
850.0   211     432
862.5           442
875.0   221     452
887.5           462
900.0   231     472
912.5           482
925.0   241     492
937.5           4A2
950.0   251     4B2
962.5           4C2
975.0   261     4D2
987.5           4E2
1G      271     4F2


EX:
for 800.0 MHz you could use a setting of "1F1" _OR_ "3F2"
for 812.5 MHz you would use "402"

core speed x 48 CORES  x 4 DIE will give you the Gh/s per ASIC x # of modules  - HW error %
= what to expect @ the pool

800 x 48 = 38400 (MHz)
38400 x 4 = 153600 (MHz)
153400 x 4 (assume a Jup) = 614 400 MHz

Subtract the HW errors (percentage) from the total above and you should be close to what the pool reports.

Smiley
YMMV

EDIT: spelling

in theory this is true? because my KNC only reaches 221/ 648GH ...

I must have missed the code on how to change OC on a die by die basis.

How can that be done?

I have done the same with one of my older units.. With the voltage control on the dies I bumped everything to about -0.0860 volts to keep it stable and keep the dies alive... I did have a troublesome die  that simply would need a lower OC than the 241 I am running on most so I would drop it to 211 to keep it stable..

humble thanks goes to ncs0ne.

I wonder what to do with knc, would like to buy jupiter bu hashrate is exploding at a pace that nothing seems reasonable. Perhaps I'll just help community by running bitcoinqt.

It would be fun to overclock neptune, anyone donating theirs to me?  Cool

Yes you can have all the Neptunes I ordered!

can be overclocked the november jupiter or not???

why dont you just start to read the fuckn thread? seriously you act like a little 5-year old.

+100

He asked me about a dozen questions via PM, when I gave him my BTC address for a donation, he stopped PMing me.

I love when a plan comes together

how is the extra watt after overclocked the jupiter?Huh

does anyone know?Huh

do you read any previous posts? you ask very often things that were already answered.


again??? ...read the posts!!!!!!!!!!!
