# AMD graphic card voltage manager
|
||
|
|
|
||
|
|
This tool can be used to overclock you AMD graphic card on Linux
|
||
|
|
|
||
|
|
## Install
|
||
|
|
|
||
|
|
```bash
|
||
|
|
cargo install amdvold
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Available commands:
|
||
|
|
|
||
|
|
* `setup-info` - prints information how to enable voltage management on Linux (see Requirements)
|
||
|
|
* `print-states` - prints current card states
|
||
|
|
* `change-state` - change card voltage states
|
||
|
|
* `apply-changes` - apply changes
|
||
|
|
|
||
|
|
## Changing states
|
||
|
|
|
||
|
|
Positional arguments:
|
||
|
|
* `index` Profile number
|
||
|
|
* `module` Either memory or engine
|
||
|
|
* `frequency` New GPU module frequency
|
||
|
|
* `voltage` New GPU module voltage
|
||
|
|
|
||
|
|
Optional arguments:
|
||
|
|
* `-a`, `--apply-immediately` Apply changes immediately after change
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
amdvold 1 engine 1450MHz 772mV
|
||
|
|
```
|
||
|
|
|
||
|
|
## Requirements
|
||
|
|
|
||
|
|
To enable AMD GPU voltage manipulation kernel parameter must be added, please do one of the following:
|
||
|
|
|
||
|
|
* In GRUB add to "GRUB_CMDLINE_LINUX_DEFAULT" following text "amdgpu.ppfeaturemask=0xffffffff", example:
|
||
|
|
|
||
|
|
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 cryptdevice=/dev/nvme0n1p3:cryptroot amdgpu.ppfeaturemask=0xffffffff psi=1"
|
||
|
|
|
||
|
|
Easiest way is to modify "/etc/default/grub" and generate new grub config.
|
||
|
|
|
||
|
|
* If you have hooks enabled add in "/etc/modprobe.d/amdgpu.conf" to "options" following text "amdgpu.ppfeaturemask=0xffffffff", example:
|
||
|
|
|
||
|
|
options amdgpu si_support=1 cik_support=1 vm_fragment_size=9 audio=0 dc=0 aspm=0 ppfeaturemask=0xffffffff
|
||
|
|
|
||
|
|
(only "ppfeaturemask=0xffffffff" is required and if you don't have "options amdgpu" you can just add "options amdgpu ppfeaturemask=0xffffffff")
