Topic: Hacking The KNC Firmware: Overclocking - page 34. (Read 144362 times)

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.)

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

Yes it does not respond sadly

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

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..

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

Yes you can have all the Neptunes I ordered!

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? 

rofl 

*Oh crap, this reminds me that I promised temen a donation I forgot about...shame on me
It's on its way now.

ahahahha

+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

The list again


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


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.


YMMV

EDIT: spelling

+1

so you dont have read the thread!

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

i read but only see overclocked for octber jupiter not for november jupiter

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

can be overclocked the november jupiter or not???
