Antminer S9K custom firmware to overclock

[DonnovanSA]

Hey everyone

Anyone knows where to find S9K custom firmware to load to overclock.

I dig up here on the forum and search on Google and I couldn't find any overclocked firmware.

There is a custom firmware that I found but it's not overclocked but it can unlock some features like SSH and fan control.
You can find it from here https://bitcointalk.org/index.php?topic=5253966.0


I found an old thread and it seems that there is overclocked firmware for this unit but you can only have them if you paid the license.

That thread only has a link to a modified recovery firmware and nothing more, it says

Antminer S9k
Unlocked SD image. Unlocks SSH and Disables Signature Checking. Nothing more was done to the image. To be applied using a SD card.

OP, there is no custom firmware for the S9k, and these gears are pretty low quality, I would not attempt to change any settings on them, if anything, you should be looking to underclock them.

most s9k suck really bad.

I had four of them they all run hot and under-clocking was next to impossible .

I was able to run three with the middle board not attached.

they are very stable and do the two boards at a solid 9th.

In fact they are mining on mmpool.org
