RTX 3090 Mining Overview and Overclocks – 125 MH/s on Ethereum!

With power in abundance the RTX 3090 is a beast of a mining GPU by Nividia at 125 Mh/s and the only one they haven’t capped the mining performance of yet.

The RTX 3090 does tend to Thermal throttle and can be very tedious to deal with. It will probably require a change of pads which could invalidate your warranty.

LHR limits the mining capability of a GPU in the Ethash Algorithm by up to 75%. None of the RTX 3090s are affected by LHR.

RTX 3090 Mining Overclocks

Please adjust the overclocks in small increments to find the ideal sweet spot for your GPU. Some GPUs will perform differently due to the silicone lottery so please do your own research.

Next, lets talk about overclocks, each card is different so please test and adjust in small increments.

Flux Mining Setting – 113 Sol/s at 390 Watts

Ok so lets talk about flux first, probably not the most efficient hash per Sol. But yet again with the right power cost one to consider.
