Mining Bitcoin with RTX 3090

Welcome to the Mining Bitcoin with RTX 3090 resource page. This section compiles guides and articles focused on using the NVIDIA GeForce RTX 3090 for Bitcoin mining. Whether you are a hobbyist exploring SHA-256 proof-of-work or a PC builder looking to put a high-end graphics card to work, you will find practical information covering hardware setup, software configuration, overclocking, and profitability factors.

The RTX 3090, with its 24 GB of GDDR6X memory and 10496 CUDA cores, is not built specifically for Bitcoin mining—the SHA-256 algorithm is now dominated by ASIC hardware. Nevertheless, its raw computing power can still handle SHA-256 at a modest rate of roughly 1–2 GH/s after careful tuning. Many enthusiasts use the RTX 3090 as a learning tool or as part of a multipool setup (e.g., NiceHash) that automatically mines the most profitable algorithm and pays out in Bitcoin. This makes the card a versatile piece of hardware for anyone wanting to understand mining operations without committing to specialised equipment.

To build a stable mining system around an RTX 3090 you need a reliable motherboard with at least one PCIe x16 slot, a power supply rated 750 W or higher, and a case with strong airflow. The card runs hot, especially the GDDR6X memory, which can reach 90–100 °C under load. Undervolting, lowering the power limit to 70–80 %, and ensuring good case ventilation are essential steps. Some users also replace the stock thermal pads to improve memory cooling.

On the software side, start by installing the latest NVIDIA drivers and choose a mining program such as CGMiner, BFGMiner, NiceHash Miner, or NBMiner. You will need a Bitcoin wallet address and an account with a mining pool (Slush Pool, F2Pool, ViaBTC, etc.). Pool fees typically range from 0 % to 2 %. After entering your wallet and pool details into the software, you can begin hashing and monitor progress through the pool dashboard or terminal.

Optimising performance and efficiency is key. Using a tool like MSI Afterburner, reduce the power limit (70–80 %) to lower heat and electricity draw while retaining most of the hashrate. Increase the core clock offset by +50 to +100 MHz and the memory clock offset by +500 to +1500 MHz, testing stability at each step. Aim to keep core temperatures below 75 °C and memory temperatures below 95 °C. Undervolting the core can further reduce power consumption without sacrificing performance.

Profitability depends on your specific hashrate, power consumption, electricity cost, and the current Bitcoin price. At typical residential electricity rates (above $0.10/kWh) and with a single RTX 3090 mining SHA-256 directly, profit margins may be thin. However, if you have access to low-cost or renewable energy, or if you use multipool software that automatically switches to more profitable altcoins before converting to Bitcoin, the outlook improves. Use a crypto mining calculator to input your own numbers and estimate daily returns.
