Server Memory Upgrade

This 16GB DDR4 module targets administrators upgrading or repairing registered DIMM slots in servers and workstations that require ECC protection. It is not suited for desktop boards that accept only unbuffered memory or for systems limited to lower densities.

Critical Specification

The module runs at DDR4 2400 (PC4-19200) with CL17 latency, 1.20V voltage, and a 2Rx8 registered ECC organisation on a 288-pin DIMM; matching these exact parameters is the only way to guarantee the system will recognise and stabilise the memory.

Installation Notes

Align the single key notch on the 288-pin edge connector with the slot ridge, press firmly until both retention clips click, then verify in BIOS that the full 16GB appears at the rated speed. A common issue is mixing registered and unbuffered DIMMs in the same channel, which prevents the system from posting.

Questions about this item

What does the 2400 MHz rating mean for actual server performance?

The module runs at 2400 MT/s with CL17 latency, giving the memory controller a peak data rate of PC4-19200 per DIMM in a registered ECC configuration.

How does the registered DDR4 interface affect bandwidth limits?

The 288-pin RDIMM uses a register to buffer address and command signals, allowing the platform to populate more slots without exceeding electrical loading limits at 2400 MT/s.

What physical slot and clearance does this 2Rx8 RDIMM need?

It fits a standard 288-pin DDR4 DIMM socket; the registered design adds a small buffer chip on the PCB but does not change the key notch position or module height.
