Question 2 dimms or 4 for Alder Lake?

[Mateu]

So I managed to get a 12900k and have this motherboard on pre order.

My question is, specifications list this board as dual channel. It does have 4 Dimm slots. I know I can run all 4 DDR5 slots in dual channel but would it be "better" to run 64gb as 32x2 or 16x4?
Please explain why. I'm trying learn.
Thank you!

There are no official reviews or benchmarks of DDR5 yet. Best to wait until it is released and fully reviewed.
