Kingston builds its memory to each brand's exact system list, so this module is meant for those Dell systems. Check your own model on Kingston's lookup before you plan a build.

How much memory fits

A 24-slot server fills to 3TB with this module. A 16-slot blade such as the M640 reaches 2TB. Kingston notes that RDIMM and LRDIMM modules can't mix inside one Dell system, so pick one type for the whole server.

What the numbers mean

  • 128GB 4R: four ranks of x4 chips on one module
  • DDR4-3200: 3200 MT/s, which moves 25.6 GB/s
  • CL22: the CAS latency at the rated speed
  • LRDIMM: buffer chips let a server hold more memory per channel

A server runs the module at the lower of 3200 MT/s and the processor's limit. Kingston lists 32Gbit DDP DRAM on the module, which stacks two dies per package to reach 128GB on one stick. Operating range is 0 to 85°C.

Quick answers

Does it work in a non-Dell server?

Kingston builds and tests it for Dell systems. Check your own server's guide for LRDIMM and 128GB support before you use it elsewhere.

What is DDP?

DDP means dual-die package: two memory dies stacked in one chip. It is how 128GB fits on a single module.

Does it need a BIOS update?

Check your server's BIOS version against Dell's notes for 128GB LRDIMM support before you install.

Is it RDIMM or LRDIMM?

LRDIMM. Some listings write RDIMM by mistake, so read the part number and the LR tag.
