Hello
I’ve pc with build ryzen 1500x, asrock ab350 pro4, klevv ddr4 2x8GB 2400mhz, gtx 1060, bequiet psu 600W

My ram speed clocks on 2400mhz on it’s advertisement specs, but it only works on 2133mhz on system and CPUz test
When i get into bios and load it’s XMP profile to 2400mhz, then apply it, my pc restart and wont boot into OS, just stay on bios
If i get back to previous setting, it cant boot again

Any suggestion? Does the 2133 and 2400 doesn’t really matter on the difference?
