So i have a ryzen build (7 2700) on a gigabyte b450m ds3h motherboard. I just purchased a trident z rgb kit (3200mhz). When i go to bios and activate XMP, save and restart they run all fine at 3200. But after i completely shut down my pc, next time i boot it, it wont post, i have to hold the button to turn it off, then turn it back on again just to see that the ram speed resets to 2133mhz. Bios is on latest version.
