Server ECC memory upgrade

This 4 GB DDR4 module adds ECC unbuffered memory to compatible servers and workstations. It runs at 2400 MHz with a CL17 latency and operates at the standard 1.2 V. The single-rank 1Rx8 organisation keeps electrical loading low for stable multi-DIMM configurations.

288-pin UDIMM form factor

The 288-pin DIMM fits standard DDR4 UDIMM slots found in qualified server and workstation platforms. ECC circuitry detects and corrects single-bit errors to protect data integrity in critical workloads. Unbuffered design means direct connection to the memory controller without registered buffers. Not compatible with desktop or laptop systems.

Lifetime warranty and US support

A-Tech backs every module with a lifetime warranty and provides complimentary United States based technical support. All units undergo quality assurance testing before shipment to verify reliable operation. Buyers should consult their system manual for correct slot population and channel guidelines.

Questions about this item

What does PC4-19200 mean for the DDR4-2400 interface on this module?

PC4-19200 is the JEDEC designation for DDR4-2400 and confirms the module is rated for 2400 MT/s data rate with CL17 latency.

What physical slot and keying does this 288-pin ECC UDIMM require?

It requires a standard DDR4 288-pin UDIMM slot; the ECC unbuffered keying prevents insertion into RDIMM or SODIMM sockets.

How do I install this single-rank module and what seating step is often missed?

Align the notch with the slot key, press straight down until both side clips click locked, then verify the module sits flat with no gold contacts visible.
