256GB DDR4 3200 ECC LRDIMM

This 256GB DDR4 3200 module targets servers and workstations that need maximum capacity per slot. It is not for consumer desktops or laptops that only accept unbuffered UDIMM memory.

Capacity and headroom

The single 256GB rank structure handles large virtualisation clusters, in-memory databases and heavy rendering workloads. It runs out when the platform memory-controller limit or the available DIMM slots are reached.

DDR4 LRDIMM interface limits

The Load Reduced DIMM design reduces electrical load on the memory bus so more modules can populate a channel. Bandwidth and rank count are still bounded by the DDR4 3200 specification and the host memory controller.

Questions about this item

Will this 256GB DDR4 3200 ECC LRDIMM work in a server that already has DDR4 3200 registered DIMMs installed?

This module runs at DDR4 3200 with CL22 latency at 1.20V as a load-reduced DIMM. Mixing LRDIMMs with standard registered DIMMs is not supported by server platforms; all slots must use the same memory type for the system to initialise correctly.

How can I confirm the 256GB DDR4 3200 ECC LRDIMM is running at its rated 3200 MT/s and CL22 after installation?

Enter the BIOS/UEFI or use a tool such as dmidecode or CPU-Z; the memory information should show 3200 MT/s (PC4-25600), CAS latency 22, 1.20 V operation and ECC LRDIMM type for the installed module.

Does the single 256GB DDR4 3200 ECC LRDIMM ship with any extra parts or cables, or is the module the only item in the box?

The package contains one 288-pin DDR4 LRDIMM module only; no cables, brackets, heat spreaders or additional accessories are included.
