You're using a solid setup with your Ab350 gaming board, R3 1200 CPU, and GTX 1060. Keeping the 1200 is a smart choice if you want to avoid overclocking risks without affecting newer parts. I've heard about BCLK settings but haven't found a way to adjust it on your motherboard. Maybe checking the BIOS or manufacturer's documentation could help.
Early Ryzen models lacked built-in variable clock generation, so you had to rely on a motherboard with an external clock source for BCLK OC. This was mostly available on premium boards and wasn't practical for most users. AM4 chips offer fractional ratios, which is why BCLK OC isn't necessary—since those ratios already provide extra speed. The BCLK also influences PCIe clocks on AM4, so pushing it too high can cause instability or issues with other components. It's generally not worth the effort.
The board does not accommodate it regardless of the BIOS release.
Using a Ryzen 3000 or 5000 chip could work since these processors include adjustable clock speeds based on BIOS settings. The R3 1200 does not support this feature.
