Hacking The KNC Firmware: Overclocking

[soapmodem]

Simple question: Once I edit my /etc/init.d/cgminer.sh file, how do I restart cgminer to ensure that it's picked up the changes? Will just rebooting it from the menu or web interface work, or is there a specific command-line I should use? Thanks.

sh cgminer.sh stop
sh cgminer.sh start

or

sh cgminer.sh restart

Perfect, thanks Ponchik.

how i can install one back up firmware from my jupiter?

If you edit /etc/init.d/cgminer.sh
you must run

'/etc/init.s/cgminer.sh restart'

if you reboot your changes will be lost.

It is recommended to make a copy and store it in /config
(it will still be there after a reboot)

then run it with

'/config/cgminer.sh restart'

YMMV

Great, thanks again.

"/etc/init.d/cgminer.sh restart"

Will restart cgminer with that cgminer.sh.

Then just "screen -r"



If the miner reboots I think cgminer.sh gets reset so make a backup to the config dir after you are happy with your oc settings.

"cp /etc/init.d/cgminer.sh /config/cgminer.sh.overclocked"

Then if/when you need to reboot the miner just copy that over the reset cgminer.sh script.

"cp /config/cgminer.sh.overclocked /etc/init.d/cgminer.sh"

and run the "/etc/init.d/cgminer.sh restart" command.

Hi all.

When 1.0 unified firmware was published I immediately tried it. It was ok but my saturn was down to 370gh/s with it. Tried replacing cgminer.sh with old-one but it was always throwing errors on vrms even with mild overclock settings. I thought that there is a conflict on how this firmware interacts with asic clocks and how the old one interacts with asic clocks but now Im not sure.

Nov saturn still stable at 500gh/s but would like to lower voltages to get perhaps a little more out of it=) I have 3 arctic fans in front of asics and heatsinks put on vrms. Clocks are between 361 and lowest is 2E1 I think, each vrm-pair tuned individually.

How to proceed if I want to lower voltages on vrms? By running 1.0 firmware and just using that? Last time this ended quickly with all errors on vrms when trying old cgminer script.

Anybody running old cgminer script with new firmware succesfully?

Thanks in advance

[Kenshin]

somebody can explain me how change cgminer for bfgminer?

You can go to the mining pool page, at the bottom of the page, you can click bfgminer.

But I found that cgminer hash faster on my Jupiter.

Plz help somebody, how to manually set frequencies in v1.0 firmware?
There is no "0x86" lines in new cgminer.sh

I use the same file I used with 0.99-1 tune.

If you need the file you can either dig thru this thread for a copy
or downgrade, save file, and upgrade again.

if you go the downgrade method
once downgraded
'cp /etc/init.d/cgminer.sh /config/cgminer.sh'
Then edit it as you like.

YMMV

My November Jupiter is set at 291, as per the following line in cgminer.sh:

Code:

cmd=$(printf "0x86,0x%02X,0x02,0x91" $c)

Is there a list or chart of values somewhere (ie 0x02,0x91 = 291)? I have good temps (50-60C). How can I push it a bit higher? Thanks.

My list is below
291 would be 1050Mhz

2A comes after 29

Code:

SPEED     setting 
700.0	1B1	     372	
712.5		     382
725.0	1C1	     392
737.5		     3A2
750.0	1D1	     3B2
762.5		     3C2
775.0 	1E1	     3D2	
787.5		     3E2	
800.0	1F1	     3F2
812.5	             402
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
1000	271	     4F2

the formula is,
 take the first 2 digits,
 convert to decimal (for decimal result),
 multiply by 25Mhz,
 add 25Mhz


EX:
29 hex is 41 decimal

25x41=1025
1025+25 = 1050Mhz clock

YMMV

Total hero material. Couldn't have asked for better, thanks tolip!!

*edit: pushed them to 1100Mhz and the machine locked up completely, had to reflash. Backed off to 1075 and it's stable. Thanks again.

*edit2: well wouldn't you know it, locked up at 1075 too... soo, I'm back where I started. Well worth a try, though.

which is the maximum OC for Jupiter October 4 VRMs?

stable?  if you dont want to babysit them, 241 / 925Mhz is pretty much set and forget
i put heat sinks on my VRMs though for extra no worry


with the weather starting to get warmer, I'll probably look to see what is the best clock at low power to kill the heat a bit

[elasticband]

heat is killing me at the moment. got an extractor set up but still hovering around 28-32c in my mining room. My jupiters don't like being in a room this warm.....

[tiozes]

my jupiter every week stuck settings is not seen on the website or come by the KNC ssh or anything, and when this happens runs stock speed, the only way to recover is to turn it off and on again.

Anyone else with him? the temperature does not exceed 50 ° C at any die.

my minign room 24-26ºC

I have also put it in coolers and vrms is giving me 700Gh / s.

Greetings and sorry for the English, google translator

The upper limits vary.

All ASIC may be created equal but the package (heat spreader) and the heat sink vary radically.
I inspected my Artic Coolers and one disassembled itself in my hands.
The others were far ftom flat where it matters.
It is one reason I switched to waterblocks. (main reason is/was fun factor)

The top of the ASIC heatspreader(the part you see with heatsink removed) is not flat.
Thermal compound helps mitigate but not always enough.

I suspect some poor performing die are under dips in the heatspreader.
I will deck and lap my ASICs this week and report if anything improves.
(do not try this at home OR at work, risk is high for contamination)

Fastest die I have with Oct ASIC's is 900 but not all die on ASIC will do that speed.

Enjoy what ya have!

Your Mileage WILL Vary
