ADATA has announced a new 32GB DDR4-2666 UDIMM memory product. This now means even more available 32GB UDIMMs will be available which should pressure AMD and Intel to update the BIOS on machines so that users can upgrade the memory.

The 32GB UDIMM, which sports the AD4U2666732G19-B part number, will join Adata’s existing Premier 4GB, 8GB and 16GB modules.


The AD4U2666732G19-B stick is reportedly a dual-rank, double-sided module. Unlike other memory manufacturers that are using 16Gb DDR4 memory chips from Samsung or Micron, Adata is manufacturing with SpecTek chips, which is part of the Micron Technology family. 

ADATA also mentioned that some new 32GB DDR4-2666 SO-DIMM will be available in mid September for laptop machines.

No pricing was available but currently 128GB of RAM for desktops is about $800 in Canada. With more competition, market saturation will push prices lower.

With ADATA, this now brings at least 7 known brands of memory that are offering 32GB capacity DDR4. Speeds tend to be lower and some are 2 rank configuration which is slower than one rank.

  • Corsair
  • Crucial
  • HyperX
  • Kingston
  • Micron
  • Samsung

Samsung has recently offered 256GB RDIMM memory for servers. They did this with two rows of chips on each side of the stick. This was done long ago to make larger capacity DDR2 memory for PCs back when DIMM capacity was limited.

At present 64GB RDIMM sales are sagging as 128GB RDIMM have come down in price. A busy web server or database can take full advantage of as much memory as can be provided. Now that 256GB RDIMM are being offered, it will pressure the older 64GB prices down even more.

With Samsung and Micron 16 gigabit memory chips being mass produced it means that 32GB UDIMM memory sticks will be come more widely available into 2020. Prices will be high for some time until market saturation pressures lower prices.
