Crucial’s 32 GB UDIMMs and SODIMMs Available: DDR4-2666 & DDR4-3200
 

In the summer of 2019, Crucial was among the first brands to demonstrate 32 GB unbuffered memory modules, which were based on Micron’s 16 Gb DDR4 chips. Now after a bit of a wait, those 32 GB UDIMMs as well as 32 GB SO-DIMMs have finally hit the retail market.

Crucial’s 32 GB unbuffered DIMMs and SO-DIMMs are rated for DDR4-2666 with CL19 at 1.2 V and DDR4-3200 with CL22 at 1.2 V operation. The modules are not equipped with any heat spreader and since they operate in JEDEC-standard modes, they are compatible with a wide variety of PCs that can support 32 GB UDIMMs in general.
