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.

At present, Crucial’s 32 GB UDIMMs and SO-DIMMs are available as 64 GB dual-channel memory kits priced at around $330 at the company’s website. Interestingly, the faster DDR4-3200 kits are only $2 more expensive than the slower DDR4-2666 kits. Meanwhile, Amazon.com expects Crucial’s 64 GB dual-channel DDR4-2666 SO-DIMM kit to arrive on February 3, 2020.

It is unclear why Crucial did not start selling its 32 GB UDIMMs and SO-DIMMs to general public earlier, as there are a number of brands that have been offering competing 32 GB UDIMMs using the same Micron chips for months now. In any case, Crucial’s 32 GB DIMMs are finally available.

    Wonder if these would be compatible with the Xeon E3 1245-V5 I have installed in my server PC. it can handle a max of 64gb of RAM, and I've currently have 32. I've been in need for more RAM for a while now...
