LRC Crashing in loupe view, while culling.

I recently upgraded my Windows PC and I'm curious if LRC has a known issue with DDR5 Ram, specifically when an EXPO profile is enabled (in BIOS).
While culling a shoot (previews already built, only program running is LRC, no other processes)... flipping through loupe-view starring photos... LRC eventually locks up. I have to open task manager to get it to un-hang, and it crashes LRC.
This ONLY happens when I have the EXPO profile enabled in BIOS

Runs fine when the EXPO profile isn't enabled in BIOS, giving me only 3200 of my 6000 RAM speed.
It also caps out at 30% usage when the EXPO isn't enabled. (Hits 50% with the profile enabled)
Is this just a case of the Adobe being slow to utilize current hardware?

LRC is the only program I have issues with. Benchmarking the RAM with 3dMark yields no errors or problems.

Thoughts?

Given how heavy LRC is on RAM usage you'd think it would be able to access every bit of RAM you can give it.  But it feels like it just doesn't know what to do with it.
I realize I have more machine than necesarry, so disabling the EXPO isn't a big deal... but I'm really wondering what the deal is.
