I have a B450-F motherboard. I just recently built my pc (less than a year old) I first had 2x8(16GB) at 3200Mhz and I upgraded to 2x16 (32GB) at 3200Mhz. With the 16 GBs I was able to run at 3200 but now with the new sticks, they're not running at spec speed. In bios they say they are but in task manager, speccy, and ryzen master all say its running at 1600Mhz. The timing according to speccy and ryzen master is different from the bios also? Not sure how to fix. Also, task manager, speccy and ryzen master used to say running at 3200 with the old sticks.
