Strix B650E-F ram issue

[Grio43]

I have a Strix B650E-F and a AMD Ryzen 7 7950X3D. 

I didn't dig deeper that the motherboard only supports some DDR5 configurations. My CMK128GX5M4B5600C40 is stuck at 3600Mhz... Rated for 5600. Not sure if I should return the ram or the motherboard or change bios more. Adjustments lead to a bios boot failure of the ram. I all ready flashed to the most recent bios.

Sorry I copied the wrong text. The cpu is a Ryzen 9 7950X3D

For 5600 you need the ram divider at 1:2, not 1:1. You've been doing that, right?

Hi @giri 

Any kits in that density with a modest OC are going to be potentially troublesome for the memory controller. AM5 doesn't handle this many ranks well.
I would recommend opting for a kit on the memory QVL.

Please be sure to look at the slot support on the far right column to see how the kit has been validated.
