Server-grade ECC RDIMM upgrade

This 16GB DDR4 2400MHz module is built for Supermicro X11SDV and X11SDW motherboards. Registered ECC design corrects single-bit errors and buffers address lines for stable operation in multi-slot server and workstation configurations. It will not work in standard desktop boards or alongside unbuffered memory.

Sustained data integrity under load

ECC circuitry detects and corrects errors continuously during long compute runs, preventing silent data corruption in databases, virtualisation hosts and NAS workloads. Registered signalling reduces electrical load on the memory controller, allowing larger populations of DIMMs to run at the rated 2400MHz CL17 without timing degradation.

Low-voltage thermal profile

Operating at 1.2V, each module draws minimal power and generates little heat even when all channels are populated. No heat spreader is fitted, relying on chassis airflow for cooling; the registered buffer and ECC logic add negligible thermal load compared with unbuffered equivalents.

Questions sur cet article

How much power does the 1.2 V DDR4 2400 MHz ECC RDIMM draw when the server runs all day?

Each module operates at 1.2 V, the standard DDR4 voltage, so power draw stays low even under continuous load.

What motherboard slot and chipset must I already have for this 288-pin registered DIMM to work?

You need a Supermicro X11SDV or X11SDW board with DDR4 RDIMM slots that support ECC registered memory.

Can I add this 2Rx8 CL17 module alongside the existing Supermicro MEMDR416LCL06ER24 sticks in my X11SDV-16C-TLN2F?

Yes, it replaces those part numbers directly, but do not mix it with unbuffered DIMMs — all slots must use registered ECC modules.
