128 GB DDR5 RDIMM for ThinkMate 111E-WR

This registered ECC module delivers 128 GB of DDR5 memory at 4800 MT/s with CL40 latency. It operates at 1.1 V and uses a 4Rx4 organisation on a 288-pin form factor. The part is validated for the ThinkMate Supermicro SuperServer 111E-WR platform.

Installing registered ECC memory

Installation follows standard RDIMM procedure: power down the server, open the chassis, align the module key with the slot, and press firmly until the latches engage. Because this is registered ECC memory, the system BIOS must support registered modules and ECC error correction; consumer motherboards without that support will not post. Mixing registered and unbuffered DIMMs in the same channel is a common error that prevents boot.

Suited for single-slot capacity upgrades

This single 128 GB stick suits administrators who need maximum capacity per slot in the 111E-WR without populating every channel. Buyers who require unbuffered non-ECC memory for a workstation or desktop board should look elsewhere, as registered ECC modules are electrically incompatible with those platforms. Systems that cannot supply 1.1 V DDR5 signalling or that lack RDIMM qualification will not work with this module.

Questions about this item

How can I confirm the 128GB DDR5 4800 CL40 module is running at the correct 1.10V and 4800 speed after installation?

Enter the system BIOS or UEFI and open the memory information screen; it should report the module as DDR5 4800 MT/s, 1.10 V, CL40, and show the full 128 GB capacity for the single 288-pin RDIMM.

What is included in the package and do I need any extra cables or brackets for the THINKMATE 111E-WR?

The box contains one 128 GB 288-pin DDR5 4800 CL40 1.10 V ECC registered RDIMM (part MR38400-744K1); no cables, brackets or additional hardware are required for installation in the compatible THINKMATE Supermicro SuperServer 111E-WR.

Which capacity or rank option should I choose for the THINKMATE 111E-WR if I want a single-module 128 GB upgrade?

Select the 128 GB 4Rx4 DDR5 4800 CL40 1.10 V ECC RDIMM (part MR38400-744K1); it provides the full 128 GB in one 288-pin module and is validated for the THINKMATE 111E-WR.
