AMD Memory Tweak Tool XL – Optimizing VRAM GPU (Download for Windows)

AMD Memory Tweak Tool

The released AMD Memory Tweak Tool has turned into a pretty useful alternative to modding the BIOS. The latest AMD Memory Tweak XL technology allows you to easily change the temporary memory settings, memory straps or PowerPlay table on the fly, as well as access ADL Overdrive and MMIO Register Control on newer AMD video cards based on GDDR5 / HBM memory. This means that you can change the settings and apply them directly, as well as check how they will affect performance and stability, the changes are not permanent, and as soon as there is any problem, you can easily return to the default values.

Eliovp, who describes himself on GitHub as a Belgian [crypto] mining enthusiast, created what could go down as the best thing that happened to AMD Radeon users all decade. The AMD Memory Tweak Tool is a Windows and Linux based GUI utility that lets you not just overclock AMD Radeon graphics card memory on the fly, but also lets you tweak its memory timings. Most timings apply live, while your machine is running within Windows/Linux GUI, some require memory retraining via a reboot, which means they can’t be changed at this time, because rebooting reverts the timings to default. The author is trying to figure out a way to run memory training at runtime, which would let you change those timings, too, in the future. While you’re at it, the tool also lets you play with GPU core frequency and fan-control.

The AMD Memory Tweak tool supports both Windows and Linux (GUI), and works with all recent AMD Radeon GPUs with GDDR5 and HBM2 memory types. It requires Radeon Software Adrenalin 19.4.1 or later in case of Windows, or amdgpu-pro ROCM to be actively handling the GPU in case of Linux. The Linux version further has some dependencies, such as pciutils-dev, libpci-dev, build-essential, and git. The source-code for the utility is up on GitHub for you to inspect and test.
