Optimized Ethereum Mining Settings for Nvidia RTX 3060 Ti, RTX 3070, RTX 3080 and RTX 3090 GPUs
We’ve tested and played around with a couple of Nvidia GeForce RTX 30 series of GPUs already, so that we can compile a list with the optimized mining settings for mining Ethereum with RTX 3060 Ti, RTX 3070, RTX 3080 and RTX 3090 GPUs. There could of course be some variation from card to card due to manufacturers making different versions with higher TDP levels and higher default clocks, but generally the settings below should work pretty good on any make and model from the above mentioned ones.
Some further tweaking could help in maximizing performance or optimizing power usage for a specific card, but the settings we give here should be a very good starting point for achieving optimal performance at reduced power usage when suing them for mining Ethereum (ETH). Do note that the settings below are intended for Ethereum mining and/or other memory intensive crypto algorithms such as VertHash for example, the settings are most likely not optimal for mining use where a GPU-intensive algorithm is in play!
* The clocks cited above are for use with a tool such as MSI Afterburner, overclocking the video memory in other tools might require the use of a different number for the same amount of clock increase +2000 MHz for the memory instead of +1000! The TDP level can also be set in Watts instead of percent level from the default one, so we also cited an estimated power usage in Watts as well.
An important tip especially for Nvidia GeForce RTX 3080 and RTX 3090 GPUs is to always run their cooling fans on 100% while mining Ethereum, even though the GPU temperature may be low. The reason for that is to help keep the memory chips cooler, because the GDDR6X memory these GPUs use get pretty hot while mining Ethereum specifically and you need to keep it as cool as possible. If it gets too hot you may experience drop in mining performance, resulting in lower hashrate and, so make sure you monitor the operating temperatures of GDDR6X memory you can do so with the useful free tool HWiNFO. With that software tool and more specifically the latest beta version it has you can also monitor the GPU HotSpot Temperature for Nvidia GPUs as a useful tool to diagnose possible cooling issues on GPUs that are unstable when mining.
If you manage to keep the memory temperature lower you might even push the video memory on RTX 3080 and RTX 3080 GPUs to +1100 MHs for some extra performance boost, though in our experience high operating temperatures and high memory frequency does not do well together. The GDDR6 memory used on RTX 3060 Ti and RTX 3070 GPUs does not get so hot and can easily handle +1100 MHz for the video memory in order to reach 60 MH/s hashrate mining Ethereum. It is best to try and see what your particular RTX GPUs can handle and not to end them running at the absolute maximum possible operating frequency as this may cause instability with a slight change in the ambient temperature.
