High-Capacity Server Memory Module

This 128GB DDR4 ECC LRDIMM operates at 2933MHz with CL21 latency and 1.2V power. The 288-pin load-reduced design uses 8Rx4 organisation to deliver high-density error-correcting memory for compatible server and workstation platforms. It meets JEDEC and RoHS standards.

Suited For ECC Load-Reduced Slots Only

This module fits servers, workstations and NAS systems that specifically support DDR4 ECC load-reduced DIMMs. It will not work in standard desktop computers or any system requiring unbuffered or registered ECC memory. Mixing with other memory types is not supported.

128GB Single-Module Capacity

The 128GB density per stick determines how much total memory a system can reach with available slots. Buyers needing lower per-module capacities or non-ECC memory for consumer platforms should look at different products.

Questions about this item

What comes in the box and do I need any extra parts to install this 288-pin LRDIMM?

The box contains the 128GB DDR4 2933 CL21 8Rx4 1.2V ECC LRDIMM module only; no cables, brackets or tools are included, and no additional parts are required for installation in a compatible server or workstation slot.

Should I choose the 128GB 8Rx4 LRDIMM or a different capacity or rank for my Fujitsu system?

This module matches Fujitsu part numbers S26361-F4083-E929 and S26361-F4083-L929; select it when your server requires a 128GB 8Rx4 load-reduced DIMM at 2933MHz — other capacities or ranks will not be a direct replacement.

What does the 2933MHz PC4-23400 rating mean once the module is running in my server?

The module operates at 2933MHz with CL21 latency at 1.2V and will also run at 2666MHz, 2400MHz or 2133MHz if the platform dictates a lower speed, delivering ECC load-reduced reliability for server and workstation workloads.
