A-Tech 4GB DDR4 2400MHz ECC RDIMM

This A-Tech module is a 4GB DDR4 2400MHz ECC Registered DIMM built for server and workstation systems. It serves administrators and IT professionals who need validated replacement memory for specific HP platforms. The registered buffer and error-correcting code support data integrity in multi-module configurations. It is not suited for desktop PCs that require unbuffered non-ECC memory.

4GB capacity with CL17 latency at 1.20V

The single 4GB rank (1Rx8) runs at DDR4 2400 (PC4-19200) with CAS latency 17 at the standard 1.20 volts. This capacity handles light virtualization hosts, edge appliances, and legacy application servers comfortably. Workloads such as large in-memory databases or dense virtualisation clusters will exhaust the 4GB limit quickly. The module uses major-brand chips tested to A-Tech quality standards.

288-pin DDR4 DIMM form factor

The stick conforms to the 288-pin DDR4 DIMM mechanical specification for direct installation in compatible server slots. No extra cables, brackets, or software utilities are bundled with the module. Compatibility must be verified against the system's qualified vendor list before purchase. Buyers needing heat spreaders, RGB lighting, or consumer overclocking profiles should look elsewhere.

Questions sur cet article

Will this DDR4 2400MHz ECC RDIMM run alongside my existing DDR4 2400MHz registered modules?

Mixing modules of the same DDR4 2400 speed and registered ECC type is generally supported, but the system will operate all modules at the lowest common speed and voltage (1.2V). Verify your server's memory population rules for 1Rx8 rank configuration.

How can I confirm the 4GB 1Rx8 module is detected and running at PC4-19200 with ECC active?

Enter the server BIOS or UEFI and check the memory information screen: it should show 4GB per module, 2400 MT/s (PC4-19200), registered ECC enabled, and the correct 1Rx8 organisation.

Does the 288-pin DDR4 RDIMM arrive as a single 4GB stick, or are brackets or cables included?

The box contains one 288-pin DDR4 2400MHz ECC RDIMM 1Rx8 module (4GB). No brackets, cables, or additional accessories are included.
