ThinkMate DDR5 4800 ECC RDIMM kit

This 64 GB kit contains four 16 GB registered DDR5 modules rated at 4800 MT/s with CL40 latency. It is built for ThinkMate servers and workstations that require ECC protection and registered signalling. The 1.1 V operating voltage matches the DDR5 baseline for enterprise platforms.

Upgrade from non-ECC or slower DDR5

Replaces unbuffered or lower-speed DDR5 memory when data integrity and full motherboard capacity are required. The jump is worth it for workloads that cannot tolerate silent corruption or that need the full 64 GB quad-channel population supported by the qualified ThinkMate models.

Tool-free DIMM installation

Modules seat in standard 288-pin DDR5 RDIMM slots without additional hardware. Common issues include mixing registered and unbuffered DIMMs, populating slots in the wrong order for the specific ThinkMate chassis, and forgetting to enable ECC in the system BIOS after installation.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the memory slots on a ThinkMate RAX-QE12 server?

Yes, the kit is built for ThinkMate RAX-QE12, QS12, QH12, QT12, QT16, QH24, QH4, QN12 and QH8 servers, so the 288-pin DDR5 RDIMM form factor matches those boards.

What is the correct order for populating the four 1Rx8 modules during installation?

Install all four 16 GB modules in the slots specified by the server manual, usually starting with the first channel of each CPU socket; the common mistake is leaving a required slot empty or mixing ranks.

When should the ECC registered modules be replaced if correctable errors start appearing in the system logs?

Replace the kit when the platform firmware reports uncorrectable ECC events or when correctable error counts exceed the threshold set in the server management console.
