This article will provide you with the information on how to overclock your Nvidia RTX 3080 graphics card for a best performance and Hashrate/Watt efficiency. We have performed number of tests by modifying memory clock and absolute core clock parameters on Nvidia RTX 3080 graphics card to determine the best configuration.

In this tutorial you will learn:
  • What hashrate (ethash) to expect from your Nvidia RTX 3080 card
  • What Hashrate/Watt efficiency ratio to expect from your Nvidia RTX 3080 card
  • Recommended overclocking settings for best hash rate
  • Recommended overclocking settings for best efficiency

What ethash hashrate to expect from your Nvidia RTX 3080

Depending on your environment, room temperature and other hardware configurations you should be able to expect hashrate anywhere between 98 -102 MH/s.

For anything below the above hashrate you should consider a possible hardware fault, incorrect overclocking or temperature throttling.

What Hashrate/Watt efficiency ratio to expect from your Nvidia RTX 3080 card

The Hashrate/Watt efficiency is a ratio between Watt usage and hash generation. Here, you need to make a choice based on the power cost. The higher the watt/hash efficiency ration the greater hash generation per 1 Watt. The highest efficiency per Watt we were able to obtain from the Nvidia RTX 3080 was 465.8 K hash per 1 Watt.
HOW TO CALCULATE MINING EFFICIENCY
To calculate your mining efficiency you first need to obtain hashrate and watt values. Once ready simply divide hashrate with number of Watts used. For example if your hashrate is 95.23MH with Watt usage 229W your efficiency is: ( 95.23/229 ) * 1000 = 415.9K hash per Watt

Recommended Nvidia RTX 3080 overclock settings for best hash rate

The following settings can be used to overclock the Nvidia RTX 3080 for a fastest hash rate while taking core temperature into consideration. Please note your results may vary:
WARNING
When overclocking your NVIDIA card always test in small increments and keep an eye on VGA's core temperature. Failing to do so may result in a permanent hardware damage.
