<p>I want to mine bitcoins, and I have heard that it is possible to overclock an Antminer T9. It said "maximum +200M recommended" for the overclocking. This miner runs at 10.5 TH/s and I would like to make it run at the hashrate of a more expensive miner (the S9), albeit with higher electricity usage. I am curious about bitcoin mining because of the interesting quirks of the SHA256 hash algorithm and how I get to be paid by helping discover hashes with 18+ zeroes (as of writing).</p>

<p>The link for info is at: <a href="https://www.infofuge.com/question/how-to-overclock-antminer-t9-to-increase-my-profits/" rel="nofollow noreferrer">https://www.infofuge.com/question/how-to-overclock-antminer-t9-to-increase-my-profits/</a></p>

<p>Note: if there is a higher safe limit, say, 15 TH/s, I would like you to specify it.</p>

Is it possible to safely mine bitcoin at 13.5 TH/s with hardware with 10.5 TH/s?

You’re not going to get any solid answers for what is safe and possible. Mining hardware varies a lot in what the chips can actually perform at reliably, even between individual units of the same model.
