16GB DDR4 ECC Unbuffered module

This 16GB DDR4 3200 module delivers error-correcting code protection in an unbuffered design. It suits servers and workstations that need data integrity without registered memory overhead. The single-rank layout keeps electrical loading light for multi-slot configurations.

288-pin installation fits standard DDR4 slots

The module seats in any 288-pin DDR4 socket at the rated 1.20V. Alignment keys prevent reversed insertion. Systems that require registered or load-reduced DIMMs will not accept this unbuffered stick, so verify the platform specification before ordering.

CL22 timing holds steady under sustained load

Continuous workloads run at the specified 22-22-22 latency without throttling. ECC correction operates cycle-by-cycle, maintaining throughput during extended compute or virtualization tasks. The 3200 MT/s data rate remains stable across populated channels.

Questions about this item

How do I confirm the module runs at DDR4 3200 with CL22 timing after installation?

Enter the system BIOS or UEFI and verify the reported speed shows 3200 MT/s and the timings read 22-22-22 at 1.20V.

What ships with the KSM32ES8/16ME and what must be sourced separately?

The box contains a single 16GB 288-pin DDR4 UDIMM; any additional modules, a compatible motherboard with DDR4 slots, and CPU cooler clearance are separate.

Which capacity and rank should I choose for a dual-channel server board with four slots?

This model is a 16GB 1Rx8 stick; populate identical modules in matched slot pairs to enable dual-channel operation.
