Corsair RAM reporting 2133 MHz, wont boot when clocked to normal speed

[luxvxn]

So I have just changed out the motherboard on my system, I have changed it to the ASUS TUF Gaming B450-PLUS II : TUF GAMING B450-PLUS II | Motherboards | ASUS USA

And when I enter the bios, the Memory Frequency is set to Auto. I booted into Windows and the RAM was reporting as 2133 MHz. I went into the bios and set the frequency to 3200 MHz, and then the system will not POST.

 

I have flashed a new BIOS version, and the problem still occurs.

 

I have two sticks of Corsair Vengeance LPX 16GB 3200 MHz : VENGEANCE® LPX 32GB (2 x 16GB) DDR4 DRAM 3200MHz C16 Memory Kit - Black (corsair.com)

 

TD;DR: My memory is not being read correctly by my motherboard.

Don't set the speed manually. Activate your XMP or DOCP profile for you RAM in the bios.

It means that the motherboard cannot train the memory at that frequency hence the no post. Try enabling DOCP and see what happens. 3200MHz is not that high of a frequency thus most motherboards and CPU controllers should be able to run it just fine. That being said, you are running two 16GB so a b450 board might be struggling. Generally speaking the higher the memory density the lower the chance of achieving the frequency advertised on the box.

Have you checked whether this memory is validated as working on that board?

What cpu? Ryzen 2 natively suppors up to 2993mhz. Try that. Above that is considered overclocking.
