[SOLVED] Can't reach the 3200mhz on my new RAM

[RemyZins]

Hi everyone,

I just bought a new pc that has 2x8gb of ram in one of the module. Because I do some video editting I figured out that I needed more ram so I bought a couple of 16gb extra ram for the second module.
The already pre-installed ram works fine in a 3200Mhz (1600 each) frequency but the newly installed ones are limited to 2132Mhz (1066 each) like you can see on my screenshots below:

I can't enable a-xmp from my bios, probably because the first set of ram doesn't allow it. I tried to modify manually the DRAM Frequency but it doesn't change a thing.

Is there another way to reach the correct frequency on my new set of RAM?
Otherwise, should I buy another same set of RAM in order to have the same type of component in each slots? Will it be be worth it performance-wise?

For information my motherboard is a MSI B550M PRO-VDH WIFI and my CPU is a Ryzen 5 5600x.

Thanks in advance for your help.

With mixed RAM, specially that much different, you are lucky it works at all. In your case you would actually have to overclock slower RAM way too much (to 3200MHz with same Cl). If it was possible they wouldn't sell it as 2133.

But the RAM i bought is supposed to work at 3200MHz (Corsair Vengeance LPX DDR4-3200) so it wasn't sold at 2132. But yes, I guess mixing RAM here wasn't such a good idea.

Without XMP it's JEDEC "Normal" is 2133 MHz You can try with help of DRAM-Calculator-for-Ryzen-1.7.3

It's kind of confusing with what you wrote so I'll guess you started with one stick of ram and you bought another stick of ram and the 2 don't do what you want.

If true send the new stick back and shop for a 2x kit of the size and speed you want.
Remove the old ram and install only the kit in the proper slots.

It looks like you have the RAM in slots 1 & 3. I expect the motherboard instructions say it should be 2 & 4 as that’s the normal setup when running 2 dimms. Try moving the RAM to 2 & 4.

In fact I had 4 dimms, 2x8gb (in slots 2 and 4) that was already installed in my setup and 2x16gb (from another brand) that I added in slot 1 and 3.

When I added the 2x16 in the remaing slots it caused my bios to consider each dimm as a single channel.

I have now removed the 2x8 and just put the 2x16 that I recently purshased in slot 2 and 4 and everything is working correctly. It's now shown as a dual channel and I was able to activate XMP to reach the correct DRAM frequency.
If I need more RAM I will just consider buying again the exact same kit for each one of my dimm to be the same.

Thanks anyway guys for your help.
