16 GB ECC UDIMM for servers

This 16 GB DDR4 module runs at 2400 MHz with CL17 latency and 1.20 V operation. It is built as an unbuffered ECC UDIMM using a 2Rx8 rank layout and major-brand chips. The stick targets administrators who need error-correcting memory for compatible workstation or server boards.

288-pin DIMM with major-brand chips

The standard DDR4 DIMM form factor fits any 288-pin UDIMM slot that accepts ECC unbuffered modules. Major-brand components and factory testing aim to deliver consistent reliability in multi-module configurations. Buyers who need registered or load-reduced DIMMs cannot use this product.

Low-voltage DDR4 thermals

At 1.20 V the module stays within standard DDR4 power limits, helping keep system thermals manageable under sustained workloads. No active cooling is required on the memory itself. Systems with restricted airflow or non-ECC-only memory controllers are not supported.

Questions about this item

What DDR4 speed and PC4 rating does this ECC UDIMM run at?

This module operates at DDR4 2400 MHz with a PC4-19200 data rate, delivering 1.2V standard voltage and CL17 latency for server workloads.

What physical slot and pin count does this 288-pin DIMM require?

It fits a standard DDR4 UDIMM slot with 288 pins; the 2Rx8 rank layout and unbuffered design match the Hynix HMA82GU7AFR8N-UH form factor exactly.

How do I install this ECC UDIMM and what common step is missed?

Power off the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that ECC is enabled — many forget to enable ECC in firmware after seating the DIMM.
