My complete guide for setting up the ASRock BC-250. You can’t beat its price for performance, and it’s perfect for those who love projects. For those looking for a full guide, with all the juicy tips and tricks, please continue… Don’t bother with buying two fans. Only one really makes a difference. See very helpful Reddit post. Out of the box, the BC250 GPU is locked to 1500MHz. The cyan-skillfish-smu GPU governor allows for dynamically scaling the GPU clock speeds to match demand. Highly recommended for both decreasing idle power usage, and dramatically increasing game performance. These are extremely safe defaults, meant to work on everyone’s BC250. However, there’s a good chance you can squeeze out more performance with less power while also improving your system’s thermals. Begin with updating the frequency-range. The max of 1850 MHz is a sweet spot once you enable the additional GPU CUs (compute units) in the next step. Going beyond it doesn’t improve performance much and only dramatically increases power-draw and heat. If you don’t enable extra CUs, then you’ll need to bump the max MHz to 2000 (safe) and up 2200 MHz if you can. But realistically there is no reason to do this once you enable the additional CUs. We’ll start by lowering the minimum frequency-range. This will improve power-draw on idle and in less-demanding games. Follow the process below. Next, I like to adjust the load-target values. This is entirely personal preference, feel free to skip. These are percentage values of GPU utilization. Upper defines at which percentage the GPU must be used to clock up. Lower defines the percentage of utilization for clocking down. The defaults are very unwilling to clock down, even in lesser demanding games.
