Question Gigabyte B550 Aorus Elite v2 RAM Issues

[Joker666]

Hello!

I just upgraded my memory from 32gb to 64gb (got another 32->2x16 of the same memory) at 3600Mhz.
When i had only 32gb i enabled the XMP profile and there weren't any issues. Now that i added another 32gbs of RAM, even if i enable or disable the XMP profile it shows my memory to be at 2133 Mhz.

Note: Already did memory tests and it was all good. Also i switched RAM sticks between them.

Current pc config:
MoBo: Gigabyte B550 Aorus Elite v2
CPU: AMD Ryzen 7 5800X3D
Memory: Corsair Vengeance RGB Pro SL 64 Gb (4x16)
GPU: Saphire RX 6950 XT
PSU: Asus ROG Strix 850W gold

Thank you in advance!

Ram is often not compatible when purchased separately in two kits , even if identical specs.

In addition it's difficult to get 4 sticks of RAM (even a matched 4 stick kit) to run above 2666, very difficult to get above 3200. It's almost certainly not going to happen by just enabling XMP settings.

With XMP set the CPU memory controller will try to train the kit at bootup for 3600. If, or when, it fails it will continue at a default DDR4 memory speed of 2133. You might try setting XMP but manually setting the RAM clock speed to 2666 to see if that works. If it does, be sure to run a memory test before declaring finished. If you want to try to try for 3200 or 3600 you'll probably have to fiddle with timings and/or increasing DRAM voltage.

It may seem like you're going backwards with low 2133 DDR4 clock speeds but if you really need 32GB of memory in your application even that will be a vast improvement over working with Windows' virtual memory.

Exactly this.
