Question First DDR5 64GB RAM sticks are here - what can these do ?

[Quinn2_Santini3]

It's value RAM series, so it has no EXPO profile etc. And since it works on 1.1V, it's only 6400MHz and its Trc latency is atrocious.

• Kingston ValueRAM CUDIMM 64GB, DDR5-6400, CL52-52-52, on-die ECC, CKD

But everyone knows that higher voltage cures that.
Question is, why have they offered it without EXPO and higher frequency/voltage profiles ?

Is it merely because there is no demand (gamers and OCers are happy with 24GiB sticks?) or because it these sticks OC like ass ?
Has anyone tried them on AM5 ?

They are CUDIMM's so there has to be support for passhtrough in BIOS, so the next quuestion is does passthrough with Zen5 run as well as if it was ordinary stick,
or does it work only in "limp-mode" - just at lame-ass speeds like 4800MHz etc ?

Interestingly, Crucial is offering something similar, but as UDIMM (no CLK regen on the stick), but at two notches lower frequency, albeight at less Trc latency.

• Crucial Pro DIMM Kit 128GB, DDR5-5600, CL46-45-45, on-die ECC

This one also has SO-DIMM version with the same properties.

Even though they are new, they are priced decently, under €3/GiB... 🙄

"Value RAM" Kingston speak for cheap, low binned chips using barely working chips. In this case probably leftovers from production of much faster chips that didn't make the grade. Control chip set to 6400MHz JEDEC standard so no XMP/EXPO needed.

Fine, but where are those A-grade 64GiB sticks that these are supposed to be left-over for ?

Nope. These are just some fast 24GiB CUDIMMs. There are plenty of those around, some significantly faster.

But no fast 64GiB models.
