ANTMINER S9 MESSAGE LOW HASHRATE CHIP

[hymperion]

Hello everyone, it often happens that hiveos gives me the error: "Auto-tune found a low hashrate chip, fixing"

in the last 2 days it has happened to me 3 times. I have no overclocking overclocking and the temperatures are also quite low.

is it a common problem of the S9 or are they the first signs of failure of some board?

As far as I can know, the main task of autotune is to make the hash rate higher and energy consumption lower (auto-tuning keeps the consumption indicated in the config file).

If it's auto-tuning, then your miner is pushing the miner to consume more power to produce more hash rate. So it means it's overclocking, but the problem is if you are still using the stock s9 PSU, it can't provide enough power, which can lead to some issues like your issue.

So better manually set the power depending on what PSU you are using.

i have 1800w power supply and set the OC to 1140w, i don't think the problem is due to that.

If it's not a PSU, it's a program since you use hiveos with autotune config.

Look at the error carefully; the hiveos is fixing it automatically for you don't need to do anything, but if you don't want to see the error, then manually set the frequency under chips config.

Still you push the hashrate over the limits from the manufacturer, that are there for a reason. The reason is that not all chips can take a higher hash raste. So if you don’t want this error you need to lower you limit. Maybe try 1100 watts.

now it's 6 days that I no longer give the error.
