ดูวิดีโอตอนนี้ 3 Easy Ways to Overclock a GPU | ASUS GPU Tweak III

This video shows three ways to use GPU Tweak III to get more FPS and faster render times.

This video is split up as follows:

00:00 Introduction and installation
00:29 OC Mode
00:44 OC Scanner
01:15 Sliders

OC Mode: A button at the top of the interface that increases the Power Target and GPU Clock by a preset amount.

OC Scanner: An Nvidia technology that automatically tests and improves GPU clock speed at every voltage level to deliver an optimized voltage-frequency curve.

Sliders: A set of manual tuning options so that users can directly tinker with the power, voltage, and both GPU and memory clock.

The video only covers the basics of overclocking, showing some of the simplest options available. For users who want to push their graphics cards further, read some extra info about the sliders, below.

Power Target:

Most graphics cards have a Power Target limit that is set by the manufacturer for how much extra power the graphics card can safely take. With a Power Target above 100%, the graphics card will be allowed to consume more wattage, as long as its temperature does not go too high. If you have a high-end graphics card like an ROG Strix model, you can gain a significant boost usually by maxing out the Power Target. Similarly, you can make a graphics card run cooler and quieter by decreasing its Power Target, albeit at reduced top-end performance.

GPU Voltage:

On the other hand, the GPU Voltage control determines how much voltage the graphics card can attempt to use. With higher voltage, a GPU can sometimes bump up to a higher frequency.

Many AMD graphics cards have the voltage set to maximum by default. Unless you are trying to make the GPU run cooler or more efficiently, this can be left as it is.

For Nvidia graphics cards, this is expressed as percentage above the stock voltage amount, so setting the GPU Voltage to 20% means that the GPU can attempt to use 120% of its stock voltage. GPUs may become much hotter with higher voltage, and instability may occur, so this setting is one that requires more care.

If trying to find a graphics card’s top voltage, ASUS recommends starting low (10-20%) and testing stability first. Then, gradually increase voltage by about 5% each time, testing stability with each change. After finding a stable voltage, gradually raise GPU Clock.

GPU Clock:

Moving this slider generally changes the GPU frequency by a given amount, but the value is actually an offset from the voltage-frequency curve. If the offset is higher than the stock setting, when the GPU boosts, it will attempt to use the higher frequency. But if it cannot reach that clock speed stably, it will fall back down to a lower voltage.

Increasing the GPU Voltage slider can give more headroom for the GPU to reach higher clock speeds, so these two settings can be adjusted in tandem. Raising both too high will have diminishing returns for overall performance, partially because every GPU has a limit to its overall silicon quality, and partially because the chipset will generate much more heat this way.

Memory Clock:

Similar to GPU Clock, Memory Clock simply raises the frequency of the VRAM. But memory speed is relatively independent from other settings in the card. This can be increased safely in increments of 100MHz until the display starts showing artifacts under load. Once its highest stable speed is found, that setting can be usually used with other GPU overclocking improvements, but if instability occurs while overclocking both the GPU and memory, reducing the memory clock will typically retain better overall performance.

What is the “voltage-frequency curve” that has been mentioned above?

Every graphics card has an algorithm that determines how much voltage is needed to handle its current tasks while still delivering adequate performance. When the graphics card is using a certain amount of voltage, it is limited in how much clock speed it can handle stably. The target frequency at each voltage level is saved in the graphics card driver, and when visualized in a graph, those points can be shown as a curve.

That curve can be adjusted on graphics cards with Nvidia GPUs to improve performance and optimize efficiency. The OC Scanner can do that automatically, but advanced overclockers can tinker with the resulting curve further for greater gains.

GPU Tweak III has a tool for adjusting that curve, called the “Voltage-Frequency Tuner”. Go here for another tutorial on how to use it: rog.gg/GT3-VF-Tuner
