Overclock S9 is possible. Note you will damage your chips if you get wrong and will kill miner!
Best to leave set at standard with overclocking issues can show more HW/Error /Reject +more issue can happen.

Stick to standard unless you are feeling brave.

I have previous experience with overclocking CPUs and GPUs. I think that I have all prereuisits for overclocking - reliable 2000W power supply, cold place (15 Celsius degree or less) where the minner is placed. I will monitor the temperature of the chips and fan speeds.

My main fear is Do I have a way to return the old frequency to the device in case it does not work?

For example when I overclock CPUs I can make hardware reset with jumpers of the motherboard bios setting. As result the device start wotking normally with default settings.

Can I do the same with AntMiner or if the configuration is wrong the whole miner will die without way to restore default configuration?

Yes there is a reset that can restore default your s9 miner you can found the reset near to ethernet but first you need to wait for 2 minutes afte bootup before you can reset it tp default config..
There is also other way to reset that can be called soft reset just login to control panel and goto upgrade you can see the reset to default and perform the reset..
Hope that it can help you to reset your hardware if ever you made a wrong setup then just do a reset... make sure that everything is fixed in the socket because there are sometimes having a firmware fault when resetting..

Overclocking bitmain hardware is flat out stupid. You will kill your miner, then you will come to the forum and whine about it.

This isnt a PC, it doesnt process data like a PC, you dont overclock it like a PC.

Bitcoin FTW!

I'm also pretty sure overclocking Antminers with an active warranty voids it. Shipping costs and return costs for Bitmain are already expensive on their own, and it's really not worth overclocking an S9 when it's already good enough. You'll just end up with a brick that's barely salvageable.

when you overclock you can change the values back if you have an issue but note if you damage the chips then you have a very expensive paperweight.

I never heard to increase more than 650Mhz possible that your miner could not run properly or getting error while running it with higher than 650Mhz and can be damaged any parts or chips of your hardware. Honestly 650Mhz frequency is not recommended..
Overclocking can be really damage your hardware and i think much better to use the default setup instead if you wanted to run your hardware for too long and for safety purposes.

worst case scenario the chips die and you now have a paperweight.

Hello,

I have AntMinters S9 14TH/s model.

It is working very well, but I think that miner can produce much more hash power than 14Th/s.

I know that old models have "Advanced settings" tab where owner can change the frequency of the chips, to change fan speed and etc.

Unfortunately my miner does not have such option. So I used the trick explained here

Now I see "Advanced Settings" and I can change the Frequency betwen 100 and 1000Mhz.

My current Frequency(avg) is 626.61MHz.

The question is what will happens if I increase the Frequency to 650 or 700Mhz?

I afraid that the miner can die.

In that worst case scenario can I restore the default frequency with hardware reset button ? or if the new frequency is not OK, I will lost the whole device.

Thank you in advance!
