128GB DDR4-2666 ECC Registered Server Memory
This 128GB module uses 288-pin DDR4 SDRAM rated at 2666 MT/s with PC4-21300 bandwidth. It targets servers and workstations that require error-correcting code and registered signal buffering for high-density configurations.
Installation notes and common issues
The module plugs into standard 288-pin DDR4 RDIMM slots and is keyed to prevent misalignment. Builders must verify that the platform supports octal-rank registered DIMMs and the CL19 latency profile, otherwise the system may fail to post or cap usable capacity.
Octal rank density constraint
Octal rank organisation allows 128GB in a single stick but increases electrical load on the memory controller. Platforms limited to dual-rank or quad-rank modules cannot use this part, so the rank count is the decisive compatibility filter.

Fragen zu diesem Artikel
How can I confirm the 128GB DDR4-2666 module is running at the correct CL19 latency after installation?
Enter the system BIOS or UEFI and verify the memory frequency reads 2666 MT/s with CAS latency set to 19; the registered ECC design also allows the OS to report corrected error counts, confirming active ECC operation.
What comes with the HMABAGR7A4R4N-VN module and what must I source separately?
The box contains the single 128GB 288-pin DDR4 registered DIMM; you must provide a compatible server or workstation motherboard with DDR4 RDIMM slots and a CPU that supports octal-rank registered memory.
Which capacity and rank version should I choose for a server needing maximum density per slot?
This part is a single 128GB octal-rank DDR4-2666 registered module; choose it when your platform supports octal-rank RDIMMs and you need the highest capacity per 288-pin slot.
