Uplift Power Play
UPP: Uplift Power Play
A tool for parsing, dumping and modifying data in Radeon PowerPlay tables
UPP is able to parse and modify binary data structures of PowerPlay tables
commonly found on certain AMD Radeon GPUs. Drivers on recent AMD GPUs
allow PowerPlay tables to be dynamically modified on runtime, which may be
known as "soft" PowerPlay table. On Linux, the PowerPlay table is by default
Alternatively, one can use this tool to get PowerPlay data by:
- Extracting PowerPlay table from Video ROM image (see extract command)
- Importing "Soft PowerPlay" table from Windows registry, directly from
offline Windows/System32/config/SYSTEM file on disk, so it would work
from Linux distro that has acces to mounted Windows partition
(path to SYSTEM registry file is specified with
This tool currently supports parsing and modifying PowerPlay tables found on the following AMD GPU families:
- Radeon VII
- Navi 10
- Navi 14
- Navi 21 (Sienna Cichlid)
- Navi 22 (Navy Flounder)
Note: iGPUs found in many recent AMD APUs are using completely different PowerPlay control methods, this tool does not support them.
WARNING: Authors of this tool are in no way responsible for any damage that may happen to your expansive graphics card if you choose to modify card voltages, power limits, or any other PowerPlay parameters. Always remember that you are doing it entierly on your own risk!

Python 3.6+, click library. Optionally, for reading "soft" PowerPlay table from Windows registry: python-registry. Should work on Windows as well (testers wanted).
At its current form this is a CLI only tool. Getting help:
upp <command> --help
Upp will only work by specifying a command which tells it what to do to one's Radeon PowerPlay table data. Currently available commands are:
- dump - Dumps all PowerPlay data to console
- extract - Extracts PowerPlay data from full VBIOS ROM image
- inject - Injects PowerPlay data from file into VBIOS ROM image
- get - Retrieves current value of one or multiple PowerPlay parametter(s)
- set - Sets value to one or multiple PowerPlay parameters
- version - Shows UPP version
So, an usage pattern would be like this:
upp [OPTIONS] COMMAND [ARGS]...
Some generic options applicable to all commands may be used, but please note that they have to be specified before an actual command:
-p, --pp-file <filename> Input/output PP table file. -f, --from-registry <filename> Import PP_PhmSoftPowerPlayTable from Windows -d, --debug / --no-debug Debug mode. -h, --help Show help.
Dumping all data:
The dump command de-serializes PowerPlay binary data into a human-readable text output. For example:
In standard mode all data will be dumped to console, where data tree hierarchy is indicated by indentation. In raw mode a table showing all hex and binary data, as well as variable names and values, will be dumped.
Extracting PowerPlay table from Video ROM image:
Use extract command for this. The source video ROM binary must be specified
-r/--video-rom parameter, and extracted PowerPlay table will be saved
into file specified with generic
-p/--pp-file option. For example:
upp --pp-file=extracted.pp_table extract -r VIDEO.rom
Default output file name will be an original ROM file name with an additional .pp_table extension.
Injecting PowerPlay data from file into VBIOS ROM image:
Use inject command for this. The input video ROM binary must be specified
-i/--input-rom parameter, and the output ROM can be specified with an
-o/--output-rom parameter. For example:
upp -p modded.pp_table inject -i original.rom -o modded.rom
WARNING: Modified vROM image is probalby not going to work if flashed as is to your card, due to ROM signature checks on recent Radeon cards. Authors of this tool are in no way responsible for any damage that may happen to your expansive graphics card if you choose to flash the modified video ROM, you are doing it entierly on your own risk.
Getting PowerPlay table parameter value(s):
The get command retrieves current value of one or multiple PowerPlay table
parameter value(s). The parameter variable path must be specified in
notation, for example:
upp get smc_pptable/FreqTableGfx/1 smc_pptable/FreqTableGfx/2 1850 1400
The order of the output values will match the order of the parameter variable paths specified.
Setting PowerPlay table parameter value(s):
The set command sets value to one or multiple PowerPlay table
parameter(s). The parameter path and value must be specified in
/<param>=<value> notation, for example:
upp -p /tmp/custom-pp_table set --write \ smc_pptable/SocketPowerLimitAc/0=100 \ smc_pptable/SocketPowerLimitDc/0=100 \ smc_pptable/FanStartTemp=100 \ smc_pptable/FreqTableGfx/1=1550
--write parameter, which has to be specified to actually commit
changes to the PowerPlay table file.
Getting upp version
Running as sudo
Note that if you need to run upp deployed with pip in
--user mode with
sudo, you'll need to add some parameters to sudo command to make user env
available to super-user. For example:
sudo -E env "PATH=$PATH" upp --help
