[SOLVED] My 3000Mhz RAMs slowed down to 1467Mhz

[Terminator47]

hi,
I had kingstone hyperX 16GB Dual channel predator 3000Mhz and they were working just fine.
I recently bought a m.2 nvme ssd and pair of old Gskill 16GB Dual channel 3000Mhz and installed windows on new ssd.
WHATS W R O N G?
after windows installation I noticed frame drop on some games and task manager showes my RAM speed as 1467Mhz while in bios says 2933.
tried removing new RAMs but didn't help.
Any Idea what have I done wrong?

It is the maximum your CPU can support. Check the specs.

DDR stands for Double Data Rate so the speed advertising is a little confusing, the IO Bus clock is twice the controller clock... Hence, 2x1467~2933

1467mhz would be the true speed of 2933mhz. As it’s DDR (double data rate) then 2933mhz actually runs at 1467mhz but is caked 2933 due to the double rate 2x1467mhz. It’s running correctly for 2933mhz.
