Unlock The Full Potential of Low Hash Rate GPUs with Dual Mining (2024)

Low Hash Rate (LHR) GPUs can now mine two coins at once

Most 3000 series graphics cards purchased in recent months are low hash rate (LHR) cards. These cards have had their Ethereum mining performance reduced by roughly 50%. However, the mining community has been hard at work on circumventing these restrictions ever since they were created. The latest releases of NBMiner and T-Rex have brought LHR cards up to 70% of their original performance, and now T-Rex allows users to mine Ethereum and another coin simultaneously. Mining two coins at once with slightly reduced performance is a clever way to maximize an LHR card’s performance. In this post, I will discuss the options for mining with an LHR card and how to get the most out of your card.

Since their release last year, Nvidia’s 3000 series graphics cards have been extremely difficult to find in stock. Even today, a year after their initial release, it is getting harder to find a 3000 series graphics card. Many think that our ongoing silicon shortage is the cause, however, for the majority of their existence, 3000 series GPUs have been produced at a faster rate than Nvidia has produced past cards. Nvidia has repeatedly stated that unprecedented demand is the reason you can’t buy a new GPU in 2021. While these cards are in high demand for many reasons, a driving factor is undoubtedly how profitable they are at mining cryptocurrencies.

Ethereum mining has been extremely profitable throughout 2021 and has remained profitable despite changes to the fee structure with EIP-1559. Because mining is so profitable, there is little reason for people with free capital to pass on purchasing GPUs for mining. After all, the more graphics cards an individual has at their disposal, the more profitable mining gets.

However, graphics cards aren’t manufactured solely for cryptocurrency mining. There is massive demand from content creators and gamers for these highly performant cards, and Nvidia has received major criticism from gamers in particular for allowing miners to purchase every available card with bots from online retailers. To combat every GPU they produce being immediately purchased and placed into a mining setup, Nvidia started…
