@ -30,12 +30,10 @@ These are the variables you're likely to want to change. They are defined in [p
| Variable | Description | Default |
|------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| power_max_default_multi| Must be a float.<br/><br/>Sets the AMD GPU power limit for the newly-created `amdgpu-default` GPU profiles in `tuned`.<br/><br/>A multiplier against the board power _capability_ | `0.928793` or ~`93%`, provides roughly 300W from my 323W board capability. |
| power_max_custom_multi | Same as above but for the non-default `amdgpu` profiles in `tuned`. eg: `...-amdgpu-{VR,custom}` | `0.82` or `82%`, my 6900XT defaults to ~87% -- allowing for slightly less power |
| gpu_clock_min | Sets the minimum (dynamic) GPU clock for the non-default `amdgpu` profiles | 2000, results in 2Ghz |
| gpu_clock_max | Sets the maximum (dynamic) GPU clock for the non-default `amdgpu` profiles | 2615, results in 2.62Ghz (rounded) -- mild overclock |
| gpumem_clock_max | Sets the _static_ memory clock for the GPU. This is *not* the _effective_ data rate. That is a multiple of this depending on the type of VRAM.<br/><br/>To avoid flickering this does *not* change dynamically with load. | 1075, results in 1.1Ghz (base, rounded) |
| gpu_mv_offset | GPU core voltage offset. Takes +/- some integer in millivolts. Can be used to both over _and_ under volt. | `-25` (undervolt `25mV` or `0.025V`) |
| base_profiles | List of base tuned profiles to clone in the new AMDGPU profiles. Defaults based on `Fedora` | <ul><li>`balanced`</li><li>`desktop`</li><li>`latency-performance`</li><li>`network-latency`</li><li>`network-throughput`</li><li>`powersave`</li><li>`virtual-host`</li>|
| amdgpu_profiles | Dictionary mapping the AMDGPU power profiles found in `/sys/class/drm/card*/device/pp_power_profile_mode`.<br/><br>Allows adjustment to the automatic power/clock handling in the GPU using either predefined profiles or `custom`<br/><br/>More may be added, only three GPU power profiles are provided -- `default`, `VR`, and `custom`.| <pre>default:<br/> pwrmode: 0<br/>VR:<br/> pwrmode: 4<br/>custom:<br/> pwrmode: 6</pre>|
| amdgpu_profiles | Dictionary mapping the AMDGPU power profiles found in `/sys/class/drm/card*/device/pp_power_profile_mode` and custom power limits.<br/><br>For each item, two keys: `pwrmode` and `pwr_cap_multi`.<br/><br/>`pwrmode` maps to the number assigned in `/sys` above.<br/>`pwr_cap_multi` is a multiplier against board power capability. Must be a float, eg: `0.5` for *50%* | <pre>default:<br/> pwrmode: 0<br/> pwr_cap_multi: 0.75 # 75% relatively safe default<br/>VR:<br/> pwrmode: 4<br/> pwr_cap_multi: 0.8 # 80%, likely slight boost<br/>custom:<br/> pwrmode: 6<br/> pwr_cap_multi: 1.0 # 100%, full GPU board capability - extreme heat</pre>|
