XMP profiler

[Nexus Vail]

So i have installed new RAMs with the same freq and type, however, different in terms of brand and CL. My Kingston have CL14 while Kllisre have CL18. I installed them alternately in my slots (MoBo: Bazooka B450M). Upon installation and rebooting several times i noticed the  XMP profile was missing and Task Manager reads my RAM as 1200 Mhz only though looking at the CMD it shows the correct speed. I tried Speccy and CPU-z both were seeing the same thing (1200Mhz). 

1.) Does that mean there are RAMs that are not supporting XMP?
2.) What seems to be the issue with the these RAMs?

Please give me some insights.

Different cas latency can cause some weird issues

Try setting the ram to 2933 manually with xmp enabled 

Specs ?

That is my other concern, XMP profile was not available anymore upon installing those RAMs. I haven't tried to remove them yet to check if the XMP profile will be back though.

Use Thaiphoon Burner to check the RAM for specs

Use Ryzen DRAM Calculator to find the timings both RAM supports. Set manually.

It showing as 1200MHz is correct, since its effective speed will be 2400MHz (or actually 2400MT/s), hence the name DDR (Double Data Rate).

I will try that thanks. Though i can't change my XMP settings as of now because it is missing in my BIOS.

I read some forums about that and you have the same thoughts, although that contradicts some of, because i do found my friends with dual-channel RAMs though they seem to have their's correct when i checked their RAM speed(2 to 4 DIMM). It blows my mind after adding 2 more RAMS which now using the 4 to 4 DIMM it changes to 1200Mhz.
