Core clock settings for RTX 3070 Ti Founders Edition when mining ethereum

Author: LB 2022-01-20 550

Getting around LHR in the latest 3070 Ti cards is no easy task. I spent hours on researching how to overclock my card to squeeze out the most hashrate from the ethash algorithm and I decided to summarize my findings so that my readers can try out my overclock settings in an Ubuntu Server.

In the previous guide I shared some thoughts on how hard it is to find the best settings, especially when LHR kicks in. In another post, I uploaded some results I got on the RTX 3090 and the 3060 Ti cards and I tried to uncover the relationship between power limit and the ethereum mining hashrate.


Clearly, using low PL values can save electricity, but still there are a few parameters we have to tweak to achieve the best mining performance. One of them is the core clock frequency. This can be altered by issuing the following command on a Ubuntu Server:


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


The command above would lock the GPU core clock at 1000Mhz and this time I was interested in whether this parameter influences the ethash hashrate. I got hold of a few RTX 3070 Ti cards in late 2021 and I decided to run some benchmark calculations on these. I changed the core clock frequency from 300MHz to 1500MHz and I got the following results using T-Rex 0.24.8 to mine ethereum on a Ubuntu 20.04 server edition:


Core frequency vs. hashrate on Geforce RTX 3070 Ti Founders Edition when mining ethereum


Previously I determined the optimal PL value for this card and it was 160W. This time I set the power limit to 160W with the following command:


$ nvidia-smi -i 0 -pl 160


With the optimal PL value I started my benchmark calculations to cover the entire frequency range. The results are obtained from several hashrate outputs by averaging them throughout a few minutes of mining to eliminate larger fluctuations. From the above graph we can decipher that locking the core clock at 800 or 900MHz would give you the most hashrate. In this zone the RTX 3070 Ti produces around 50 MH/s. Clearly the card is performing worse than the older RTX 3070 Ti models and this is most likely due to the powerful LHR limitation. The latest LHR technology from Nvidia seems to be an insurmountable barrier even for the best miners on the market.
