-| 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.
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`) |
+| gpu_clock_min | Sets the minimum (dynamic) GPU clock (in `Mhz`) for the non-default `amdgpu` profiles | `700` |
+| gpu_clock_max | Sets the maximum (dynamic) GPU clock (in `MHz`) for the non-default `amdgpu` profiles | `2600`, results in `2.6GHz` (rounded); mild overclock |
+| gpumem_clock_static | Sets the _static_ memory clock for the GPU (in `MHz`). This is *not* the _effective_ data rate. That is a multiple of this depending on the type of VRAM.
To avoid flickering this does *not* change dynamically with load. | `1050`, results in just over `1GHz`; mild overclock
Actual effective clock depends on this being multiplied against the data/pump rate of the `GDDR?` GPU memory |
+| gpu_mv_offset | GPU core voltage offset. Takes +/- some integer in millivolts. Can be used to both over _and_ under volt. | `-10` (undervolt `10mV` or `0.01V`) |

- `desktop`
- `latency-performance`
- `network-latency`
- `network-throughput`
- `powersave`

| amdgpu_profiles | Dictionary mapping the AMDGPU power profiles found in `/sys/class/drm/card*/device/pp_power_profile_mode` and custom power limits.
For each item, two keys: `pwrmode` and `pwr_cap_multi`.
`pwrmode` maps to the number assigned in `/sys` above.
`pwr_cap_multi` is a multiplier against board power capability. Must be a float, eg: `0.5` for *50%* |
default:
pwrmode: 0
pwr_cap_multi: 0.75
# 75% relatively safe default
VR:
pwrmode: 4
pwr_cap_multi: 0.8
# 80%, likely slight boost
custom:
pwrmode: 6
pwr_cap_multi: 1.0
# 100%, full GPU board capability
# warning: significantly increased heat
