Unable to modify CPU frequency on MSI Z170A Gaming M3; cannot run RAM at 3200MHz
Intel has restricted overclocking on their processors for some time. If you're after that, you'd need a special CPU model—like the one with 'k' in the name. On Asus Z170 boards, baseclock overclocking is possible on non-k processors, but not on your MSI board. Regarding RAM, your motherboard supports 3200MHz, though your own RAM might not. To reach that speed, consider slightly increasing the voltage on the power supplies, though it won't make much difference since Intel CPUs generally ignored RAM speeds. Performance typically stays between 2133MHz and 3100MHz.
This setup was feasible on certain MSI boards from that period. I owned an MSI Z170A Gaming Pro or possibly the Pro Gaming model. While non-K CPUs were supported in hardware, overclocking required unofficial BIOS modifications. RAM performance was inconsistent, especially at higher speeds, and older microcode versions made compatibility with modern operating systems difficult. Generally, these components struggled to work together smoothly. It might only be practical for specialized competitive testing. Reliable performance depended heavily on the specific hardware and workload. CPU memory bandwidth has always been a challenge, and RAM speed still played a role back then—depending on what you were doing.
