Where are the DDR5 Unbuffered 256GB 64GBx4 Kits?

Now that vendors have added BIOS support on AMD AM5 & Intel 600/700 motherboards for working with 256GB of Unbuffered RAM, it is clear that if a kit comes it would work.

But I haven’t been able to find one yet!!

What ever 64GB modules I find are Registered/Buffered/Load Reduced.
So Just have to wait ???

256GB Announcements:
ASUS
Asrock
Gigabyte
MSI

In all the vendor’s press releases, they seem to refer to a
Kingston Renegade KF560C36-64 Module…
But I’m not able to find any datasheet level info as of April 2024!

From Arock’s CPU-Z screenshots, what we can make out is that they have been at least manufacturing it from Week 50 of 2023… That means Dec 2023!!

Hoping that it would show up in this page in the near future:

Support is not an indication that the product will appear soon. It will happen eventually, but I wouldn’t count on timing and even support from the current gen CPUs.

Wikipedia gives an overview of theoretical capacity: DDR5 SDRAM - Wikipedia

DDR5 octuples the maximum DIMM capacity from 64 GB to 512 GB.
(comparing to DDR4)

However there is maximum 32 GB unbuffered DDR4, and there is 128 GB registered DDR4.

48 GB unbuffered DDR5 is still new and expensive. And I still don’t see 128 GB registered DDR5.
