Capacity and configuration

This kit provides 192GB of DDR5 memory across twelve 16GB modules. It is built for administrators upgrading compatible Thinkmate servers or workstations that require registered ECC DIMMs.

Registered ECC design and voltage

Each module is a 288-pin RDIMM with on-die ECC and a registered buffer, operating at 1.1V. The registered layout reduces electrical load on the memory controller, while ECC corrects single-bit errors to protect data integrity in nearline storage workloads.

Speed grade and latency

The modules run at DDR5 4800 (PC5-38400) with a CAS latency of CL40. This speed grade must match the platform's qualified memory list; systems that only support lower DDR5 data rates or different latencies will not be compatible.

Questions about this item

Does the DDR5 4800 PC5-38400 interface run at the full 4800 MT/s on the Thinkmate STX-NL-QE16 E4?

Yes, the 12 modules are rated DDR5 4800 PC5-38400, so the memory bus operates at 4800 MT/s when the server's memory controller supports that speed.

What physical slot and clearance do the 288-pin RDIMMs need in this server?

Each 16 GB module uses a standard 288-pin DDR5 RDIMM form factor with no heat spreader, so it fits any DDR5 RDIMM slot without extra height clearance.

What is the correct population order for the 12-module kit and which step is often missed?

Fill all 12 slots following the motherboard's channel sequence, then enable ECC in the BIOS; skipping the BIOS step leaves error correction inactive.
