4 ram modules can't be overclocked

[KONPERIS]

Hello,I have an issue with my rams

CPU AMD RYZEN 3400G
MOTHERBOARD ASUS PRIME B450M-A
BIOS 1804
MEMORY XyperX 3200Mhz(4x4) HX432C16FB3K2

When I had 2x4,on XMP worked well as 3200,but today that I putted another 2x4 (total 4x4) I can't OC them to 3200 with XMP...my pc can't boot and I have to make changes on BIOS,to let them on auto without XMP profile,so they can run at 2400...can I OC them with another ways or it is just it?
My pc runs ok with 2400Mhz ram

Thank you for your replies

This is Asus' memory compatibility list for that motherboard:

Or more rather, it's the memory that Asus have tested on the board. The nearest one shown to the RAM you have is the HyperX HX430C15PB2K4/16 and you can see that 4 DIMMs of it aren't supported.

It's probably the timings that are causing the problem, as there are other 4 DIMM combinations that are fine I.e. when the timings are 15-15-15-36, you can only use 2 DIMMs. You could try manually setting the timings to something like 16-16-16-38 to see if that works at 3200 MHz. Don't forget to set the RAM voltage to the same as in the XMP profile.

I did that..1.35V and 16-16-16-38,it doestn't work nor XMP3000 nor XMP3200,and I have some crasher sometimes...when I had 2 of them(2x4) I had them on 3200,but with a lot of crashes because of VEGA11
