@ -33,7 +33,7 @@ These are the variables you're likely to want to change. They are defined in [p
| 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.<br/><br/>To avoid flickering this does *not* change dynamically with load. | `1050`, results in just over `1GHz`; mild overclock<br/><br/>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`) |
| gpu_mv_offset | GPU core voltage offset. Takes +/- some integer in millivolts. Can be used to both over _and_ under volt. | `-50` (undervolt `50mV` or `0.05V`) |
