Overclocking with the VF Tuner | ASUS GPU Tweak III

Описание

The GPU Tweak III voltage-frequency tuner streamlines manual overclocking or undervolting through its intuitive interface. Beyond just giving a basic overview of the VF Tuner functionality, this video shows a typical workflow for optimizing the performance of Nvidia GPUs.

The main parts of this video are listed here:

00:00 Introduction
00:14 Prepare the system for overclocking
00:46 Set up a quick VF curve
01:30 Fine-tune individual points

After watching the video, read below for some extra tips & tricks regarding the VF Tuner.

Power Target, GPU Voltage, and Memory Clock:

Out of the core overclocking functions, the VF Tuner only controls the same space as the GPU Clock slider. To get the most performance out of the graphics card, it is still recommended to tune the other sliders. In particular, the Power Target and GPU Voltage influence how far along the voltage-frequency curve that the boost algorithm is able to climb. For more info about those sliders, see the related tutorial at rog.gg/GT3-Overclocking and read the description.

Undervolting:

Instead of pushing the maximum frequency higher, some users prefer to perform undervolting, which involves using a lower GPU frequency and voltage level. Undervolting makes the graphics card run more efficiently, saving power and reducing heat buildup. Though not directly mentioned in the video, the section about setting up a quick VF curve 00:46 is similar to the process of undervolting.

After performing the steps shown there, some users will further optimize the curve by finding the lowest voltage that can be applied to maintain GPU stability at each frequency point. This allows the card to run at the best performance-per-watt ratio and/or helps to reduce fan speed and noise.

Alternatively, like in the video, that base undervolt can be used to more easily find how much overhead the graphics card has for further overclocking.

Save Points:

As you overclock higher, it is likely that at some point a setting will be unstable, and that can take several forms: display artifacts, screen tearing, or even program crashes or system freezes. So users don't lose progress due to critical failures, GPU Tweak III comes with a set of save points at the bottom of the VF Tuner screen.

Whenever a VF curve is applied, it is saved to the Driver Profile for use during normal system operation. If the user saves and closes the screen without applying, the curve is saved to the Previous Setting, so that it can be opened later for further adjustments. The Previous Setting is particularly useful if if the Power Target or GPU Voltage are raised, and then the user returns to the VF Tuner to test a point that turns out to be unstable.

And, as shown in the video, two additional options for the Default and OC Scanner curve allow users to return to foundational curves before starting an overclocking or undervolting session.

Lock/Unlock Voltage:

While this function's primary purpose is to allow users to test stability when the frequency is set to a certain voltage point, this also can be used by itself to force the GPU maintain its clock.

If you choose a stable clock speed and voltage and press Lock or the L key, the GPU will continue running at that frequency. Then you can leave GPU Tweak III in the background while you play a game or run a program. For some applications, this option lets the system run rather smoothly, though it is recommended that you unlock the setting when you're finished so as to not waste power or let undue heat build up.

Managing temperature on a graphics card is usually handled by controlling its fans, which is another major feature of GPU Tweak III. To see how to change fan settings, see the tutorial here: rog.gg/GT3-Fans
