Hacking The KNC Firmware: Overclocking

[joeventura]

at 0.99.2 firmware does not have these one
how will can do overclocked??




is at the command prompt:

vi /etc/init.d/cgminer.sh

Use the cursor keys on your keyboard to scroll down till you see this code:

Look for the line that says:

cmd=$(printf "0x86,0x%02X,0x01,0xF1" $c)


NOTE: some of the characters at the end (especially the F1) may be different.

The key is the line with the 0x86, when you see that you are on the right line.


change this:

cmd=$(printf "0x86,0x%02X,0x01,0xF1" $c)

to this:


cmd=$(printf "0x86,0x%02X,0x02,0x11" $c)

The student becomes the teacher!

Well done!

No no
If see my post I have problem can help me to fix it

with 201 i have 615-620 Gh/s, with 211 i have 586 Gh/s, and with high temperatures (76º) i have 597 Gh/s is that normal?

can anyone have overclocked easy like 0.99.1

0.99.2 version

You could put some fans inside the case !

New firmware's starter doesn't contain any 'spi-test' calls you could modify.
Try your old starter (with minor modifications for BFGminer). Works fine.

Hi,

I am using Oct Jupiter with 0.99.1-tune firmware. After I pressed "Reset factory settings" on Advanced tab, I can no longer access Advanced tab at all. Instead I have browser message with "Fetch advanced configuration/status failed." and "OK" button. Restarting, flashing to earlier firmware and flashing back to 0.99.1-tune does not resolved the issue. Jupiter itself is mining away nicely, but I can't access Advanced tab anymore.
Any one had similar problem?

Ctrl+F5?

Of course I tried it, doesn't work.

did you try to clear the cache?
with another browser?
private browsing (Ctrl+Shift+n)?

So is anyone trying 241 on a whole board yet for long period of time? i'm on 231 with 55a per vrm right now...tryed 241 but would have to up the volts even more as i had alotta cores go off...just wondering

[tiozes]

with 201 i have 615-620 Gh/s, with 211 i have 586 Gh/s, and with high temperatures (76º) i have 597 Gh/s is that normal?

because it gives less performance using 211? and 231 is getting worse, you have to play other parameters?

The temperature arrived at 70 ° C because the cooling stopped as it was very cold, but we have no temperature problems.

see if someone helps us get a little more power.

Is there any way to stop bermod without restart or shutdown the KNC?

regards

[giletto]

So actually is no way to OC a nov batch jupiter, right?

new firmware gives an ption to lock access to a certain IP addy, is it possible you looked it?

I didn't edit anything, i got it from another member. I think he over wrote his config so the spi changes are permanent t, that meant the changes were still there when he uploaded new firmware. bellow is what was missing in the new firmware.

Code:

# Re-enable PLL

Hi,

I am using Oct Jupiter with 0.99.1-tune firmware. After I pressed "Reset factory settings" on Advanced tab, I can no longer access Advanced tab at all. Instead I have browser message with "Fetch advanced configuration/status failed." and "OK" button. Restarting, flashing to earlier firmware and flashing back to 0.99.1-tune does not resolved the issue. Jupiter itself is mining away nicely, but I can't access Advanced tab anymore.
Any one had similar problem?

Ctrl+F5?

Of course I tried it, doesn't work.

Try to run:

waas -d -o /config/advanced.conf

Thanks!

It turned out, that this file was completely empty.
