16GB DDR5 ECC RDIMM for ThinkMate servers

This 16GB DDR5 4800MHz registered DIMM provides error-correcting memory for compatible ThinkMate server and workstation platforms. The module operates at 1.1V with CL40 latency and uses a 1Rx8 organisation built from major OEM DRAM chips. It is designed for IT professionals who need validated stability in mission-critical environments.

Check DDR5 RDIMM slot availability

Before ordering, verify that your ThinkMate model appears in the supported list such as RAX-QE12, QS12, QH12, QT12, QT16, QH24, QH4, QN12 or QH8. Confirm the motherboard accepts 288-pin DDR5 registered ECC modules and that the BIOS revision supports 4800MHz operation. Registered memory cannot be used in systems that require unbuffered DIMMs.

Single-module upgrade simplifies capacity expansion

The package contains one 16GB stick, allowing precise capacity increments without populating unnecessary slots. No heat spreader is fitted, which can improve clearance in dense server chassis. Modules are stress-tested under load by the supplier to reduce the risk of early-life failures in production workloads.
