Additionally, consider ambient room temperature, which can fluctuate significantly between summer and winter depending on your region and climate. Keeping an eye on these factors ensures stable mining performance and prevents overheating.

2. Memory overclocking

Start by gradually increasing the memory clock speed. A good baseline is +300 to +400 MHz, then adjust in +50 to +100 MHz increments.

Important: Always monitor system stability during overclocking to prevent crashes or performance drops.

Under normal conditions, the GeForce RTX 3050 operates at:

• Core Clock: 1987 MHz
• Memory Clock: 6800 MHz

With these settings, the hashrate can reach 25 MH/s.

With proper overclocking and fine-tuned settings, the Nvidia RTX 3050 can achieve:

• Memory Clock: 7950 MHz (+1150 MHz)

• Hashrate: 30 MH/s (+5 MH/s)

Pushing memory frequencies beyond +1150 MHz may cause instability in Nvidia tuning software, leading to errors or crashes.

Tip: If you want to avoid troubleshooting or potential GPU failures, it's best to cap the memory overclock at +1150 MHz for a stable and safe performance boost.

The increase in device performance when overclocking can vary, even between identical GPU models. The results depend on individual chip quality, cooling efficiency, and overall hardware configuration.

3. Power limit settings

Reducing power consumption is a key step in optimizing your GPU. Lowering this parameter helps you reduce stress on the power supply and GPU, lower energy costs, and keep temperatures under control.

Gradually decrease the power limit by 10% until you notice a drop in hashrate. This ensures maximum efficiency without sacrificing performance.

For the GeForce RTX 3050, the optimal power limit reduction stops at 80%. However, this value may vary for other GPU models.

The ideal power reduction range for most Nvidia GPUs is between 20% and 40%, balancing efficiency and performance.

4. Core clock overclocking

It’s advisable to set 0 MHz or adjust in -20 to -30 MHz increments.

After each adjustment, wait 2 to 5 minutes and check the hashrate. If the hashrate starts dropping, stop lowering the core clock to maintain optimal performance.

Core clock overclocking is the final step in configuring your Nvidia GPU.

Now that the GPU is optimized, let’s explore voltage curve adjustment. It’s a technique highly popular among crypto miners.

Voltage curve configuring is a fine-tuned optimization method that involves undervolting your GPU. Its main goal is to find the lowest possible voltage at which the GPU remains stable while mining efficiently.

Default GPU voltage typically ranges from 1.05V to 1.1V. However, manufacturers set this with a safety margin, meaning many GPUs can operate at lower voltages – around 0.9V to 1V – without stability issues.

Let’s find out how to adjust the voltage curve:

• Hold the ‘Shift’ key
• Click on any point on the voltage-frequency graph
• Lower the curve to reduce voltage while maintaining stable performance

To set the voltage to 0.975V, follow these steps:

• Identify the vertical point on the graph corresponding to 0.975V on the lower voltage scale
• Drag it upward until it aligns with the previously adjusted core clock frequency
• In this example, the target is 110 MHz at 0.975V

The next step is to finalize the voltage curve adjustment by following this instruction:

• Close the voltage curve window and apply the settings
• Open the frequency and voltage editor in your tuning software
• Allow the tool to process and auto-adjust the graph
• Launch NBMiner and monitor system stability for 3-5 minutes

If the system remains stable, try lowering the voltage further by gradually reducing it until the hashrate begins to drop. The optimal range is 0.9V to 1.05V for the best efficiency and performance balance.
