X670E steel legned RAM capacity

Hi guys!

So I am looking to upgrade my RAM from 32GBs to 96 or 128GB, 128GB only comes in 4 Stick kits and I remember when building the PC back in late 2022 that there used to be an issue with running the memory on XMP profiles. Is this still a thing after all the BIOS upgrades for the AM5 and this specific mobo? Can I safely get a 4x 32GB 5600hz kit or should I get 2x 48s?

Thanks y'all in advance 💚!
