System-specific 512GB DDR5 kit

This 512GB kit contains four 128GB DDR5 4800 ECC registered DIMMs built for the THINKMATE SuperServer 111E-WR. It targets administrators who need maximum registered capacity in that platform. The modules operate at 1.1V with CL40 timing and use a 4Rx4 organisation. Buyers who need non-ECC or unbuffered memory for a workstation should look elsewhere.

Installation follows standard RDIMM procedure

Insert each 288-pin module into the server's DDR5 slots until the ejectors lock. The registered design adds a clock cycle, so the system must support registered DIMMs or the modules will not post. Common issues include mixing ranks or voltages across channels and failing to update the BMC firmware before installation. No heat spreaders are fitted, so airflow must meet the chassis specification.

4Rx4 registered ECC at DDR5 4800

The defining specification is the 4Rx4 registered ECC configuration running at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V. This rank structure and registration type must match the SuperServer 111E-WR memory controller requirements exactly. Verify the platform's qualified vendor list before purchase because an incompatible rank or voltage will prevent boot.

Questions about this item

How can I verify the kit is running at 4800 MT/s with CL40 timing after installation?

Enter the system BIOS or UEFI and confirm the memory frequency reads 4800 MT/s and the CAS latency shows CL40; the registered ECC modules will also report their status during POST.

What does the package contain and is any additional hardware required?

The box includes four 128 GB DDR5 4800 CL40 288-pin ECC RDIMM modules for a total of 512 GB; no extra cables, brackets or cooling parts are needed.

Which capacity configuration should I choose for the ThinkMate SuperServer 111E-WR?

This kit provides the full 512 GB (4 × 128 GB) supported configuration in a single matched set, so no smaller or larger capacity options are offered for this part number.
