This is more a proof that this is possible rather than a recommended setup as this does have some boot up issues.

Was a great starting point for me on 12900K/Unify-X, everything worked fine on a kit of TG 7200, except tCWL, which was 30, and would 100% cause a hard freeze every time I tried to drop it.

Yeah I think MHz would make more sense then because the actual bits per second depends on the bus width. Certainly not megatransfers though! Unfortunately MHz wouldn't work because marketing needs bigger number.

the DDR5 memory controller on LGA1700 has 4 32bit memory channels.

I still don't get how Mbps RAM speed converts to system RAM bandwidth, even roughly. 3600 Mbps is only 450 MB/s which is less than SATA III's 550MB/s. Even multiplying by two for dual channel only comes out to 900 MB/s. Obviously this is not correct because my CPU does more than 60x that in memory read benchmarks.
