16 GB DDR5 ECC RDIMM for Thinkmate 111E-WR

This registered 288-pin module delivers 16 GB of DDR5 4800 memory with CL40 latency and 1.1 V operation. ECC and registered buffering provide the error correction and signal integrity required by the Thinkmate SuperServer 111E-WR platform. It is built for administrators who need validated, single-rank capacity in a single DIMM slot.

Major OEM chips and registered design

Samsung, Micron or Hynix components are assembled without a heat spreader, keeping the module low-profile for dense server chassis. The registered interface reduces electrical load on the memory controller, allowing stable operation across fully populated channels. Standard 288-pin DDR5 keying ensures it seats only in compatible DDR5 RDIMM slots.

Replaces non-ECC or slower DDR5 modules

Upgrading from unbuffered non-ECC memory adds data integrity protection for mission-critical workloads. Moving from lower-speed DDR5 increases bandwidth to PC5-38400 without changing voltage. The jump is worth it when the server must run validated, registered ECC memory at the platform's native 4800 MT/s rate.

Questions about this item

What speed does the DDR5 4800 interface actually run at in this SuperServer 111E-WR?

The module is rated for DDR5 4800 (PC5-38400); the SuperServer 111E-WR memory controller sets the final operating speed, which can be lower depending on CPU and DIMM population.

Does the 288-pin RDIMM fit the 111E-WR DIMM slots without a riser?

Yes, the 288-pin DDR5 RDIMM form factor matches the standard DDR5 RDIMM slots on the ThinkMate SuperServer 111E-WR motherboard.

What is the correct seating order when installing this 1Rx8 module in the 111E-WR?

Follow the motherboard manual's population sequence; a common mistake is skipping the first slot of a channel, which prevents the registered DIMM from initialising.
