What's an LHR GPU?
If you're lucky enough to own one of NVIDIA's latest GPUs, there's a chance you may have heard the term "LHR" in reference to your shiny new RTX 3000 GPU. "LHR" stands for Lite Hash Rate, and it's an artificial hardware lock on the hashrate for the Ethereum protocol for some RTX 3000 GPU models. This will result in lower earnings whilst mining with these models versus the normal, or FHL (Full Hash Rate), models. You can check whether your GPU model is one of these LHR variants by referencing the table below
| GPU Model
|RTX 3060 Ti||GA104-200||No|
|RTX 3060 Ti||GA104-202||Yes|
|RTX 3070 Ti||GA104-400||Yes|
|RTX 3080 Ti||GA102-225||Yes|
If you don't already know your GPU ID, you can usually find it in most hardware identifier apps, like CPU-Z. You can download CPU-Z here: https://www.cpuid.com/downloads/cpu-z/cpu-z_1.99-en.exe
Simply install and run the program, and once its open navigate to the "Graphics" tab at the top. From here you can view the "Code Name". This Code Name is the GPU ID for NVIDIA users. Once you know your GPU ID, you can match it to the table above and check whether your GPU model is affected.
