GPU and Memory Clock Speed Adjustments

Adjusting the core GPU clock and memory clock speeds is a fundamental aspect of overclocking. Higher clock speeds generally lead to increased performance in games and other graphically intensive applications.

• GPU Clock (MHz): This setting controls the operating frequency of your graphics processing unit. In GPU Tweak II, you can incrementally increase the GPU clock speed. It is recommended to make small increases (e.g., 10-20 MHz at a time) and test for stability after each adjustment to avoid system crashes or artifacts. The goal is to find the highest stable clock speed that your GPU can maintain under load.
• Memory Clock (MHz): This refers to the clock speed of the VRAM (Video Random Access Memory) on your graphics card. Increasing the memory clock can improve texture loading times and overall performance, especially in games with high-resolution textures. Similar to the GPU clock, adjustments should be made in small increments (e.g., 50-100 MHz) with stability testing in between. It’s worth noting that some older versions or specific GPU Tweak II configurations might display memory clock values as four times the commonly used number, so users should be aware of this difference when comparing with other overclocking guides.

Managing Voltage, Power Target, and Temperature Target

These settings are crucial for maintaining stability and preventing damage when overclocking. They directly influence the power delivery and thermal characteristics of your GPU.

Advanced Fan Control and Custom Curves

Effective cooling is paramount for stable and sustained performance, especially when overclocking. GPU Tweak II offers comprehensive fan control options to manage your graphics card’s cooling system.

• Automatic Fan Control: This is the default setting, where the GPU automatically adjusts fan speeds based on temperature thresholds defined by the manufacturer. It aims for a balance between cooling and noise.
• Manual Fan Speed: Users can set a fixed fan speed percentage. This is often used during benchmarking to ensure maximum cooling, but can result in increased noise.
• Custom Fan Curves: This advanced feature allows you to create a personalized fan curve, mapping specific fan speeds to corresponding GPU temperatures. By plotting points on a graph, you can define how aggressively your fans should ramp up as the GPU temperature increases. This enables fine-tuning for optimal noise-to-cooling balance.
• 0dB Fan Technology: Many modern ASUS graphics cards incorporate 0dB fan technology, which allows the fans to stop spinning entirely when the GPU temperature falls below a certain threshold, providing silent operation during light loads. GPU Tweak II allows you to manage or enable/disable this feature if supported by your card.
• FanConnect II / External Fan Support: Some ASUS ROG Strix graphics cards feature FanConnect II headers, allowing you to connect case fans directly to the GPU. GPU Tweak II can then control these external fans based on GPU temperatures, optimizing cooling for the entire system around the graphics card. This provides a cohesive cooling solution, though some users have reported issues with external fan control not applying correctly on Windows startup.
