Core clock settings for RTX 3060 Ti when mining Ethereum

Author: LB 2022-01-22 822

Locking the core clock frequency can significantly influence ethereum mining performance. Getting the highest hashrate for the least amount of electricity consumption is of utmost importance for miners. In this context it is expedient to find out how core clock frequency changes the number of ethash hashes on the 3060 Ti Founders Edition GPU. Let's see the details!

Finding the best overclock settings for a given mining GPU can be a daunting task. Especially because there are several miners available and also because GPU with LHR and without react very differently to changed clock frequencies. This time, after having the RTX 3080 Ti and the RTX 3070 Ti benchmarked for ethereum mining, I decided to find out the most optimal core clock value for the RTX 3060 Ti card using the latest t-rex miner. In one of the previous articles I measured the ethereum mining hashrate with respect to PL (power limit), having found the best PL settings for the RTX 3060 Ti Founders Edition now I'm in a position to play around with the core clock. The core clock can be set using the following nvidia-smi command in Ubuntu (I guess HiveOS and other Ubuntu based mining operating system use the same command to lock core clock):

$ nvidia-smi -i 0 -lgc=1000,1000

This time I scanned over the range of 400MHz to 1500Mhz to find the best OC settings for this card. As mining hashrates fluctuate over time, I decided to use a longer time period and I averaged the outputs to get a more reliable result. Mining profitability for 24 hours or for a longer period depends on the average hashrate after all. Bellow are the results I got for the 3060 Ti Founders Edition card:

The maxima of the graph is at 1300MHz. Core clocks lower than this value would give you less hashrate and increasing the core clock value much higher than this would waste electricity without significantly improving upon the ethereum mining performance.
