X370 Pro4 unable to XMP, do I need B die?

[URL=][/URL]I have BIOS 5.0 and I'm unable to run my G.Skill Ripjaws V 3200 hynix RAM at any XMP setting above 2133 without random memory crashes. I've tried 1.4v RAM voltage which didn't help, the BIOS has no LLC or SoC setting, but SoC is 1.1v in Ryzen Master. I'm running a Ryzen 7 1700 @ 3.9ghz/1.34375v prime95 stable. If I replaced it with B die RAM, will that allow for XMP speeds without crashes?
