So I bought a new ryzen 5 1600. And I heard that performs better with higher frequency ram. So I bough the Gskill Flare x 3200mhz because I didn't want to have any surprises. So, I enabled the xmp profile in the bios. Cpu-z now says I have 3200mhz but windows task manager tells me I only have 2400mhz. (that's how it works, right? you multiply it by 2)
So what's going on? Who should I trust? CPU-Z or Task Manager?
PS: The bios also says the memory is clocked at 3200mhz.
