8GB DDR4 2666MHz ECC UDIMM

This 8GB DDR4 2666MHz ECC UDIMM module provides error-correcting memory for servers and workstations that require data integrity. It operates at 1.20V with a CAS latency of CL19 and uses a 1Rx8 rank configuration. The module is a compatible replacement for HP part numbers L43768-001 and L36845-001.

288-pin DIMM installation

Installation follows the standard 288-pin DIMM form factor used in compatible DDR4 server platforms. The unbuffered design allows direct connection to the memory controller without a register chip. Verify your system supports ECC unbuffered memory before purchase, as registered or non-ECC modules are not interchangeable with this specification.

DDR4 2666MHz platform limits

The DDR4 2666MHz interface caps memory bandwidth at the PC4-21300 rating for this module. System maximum capacity and supported module population depend on the specific platform memory controller and BIOS, which are not defined by this module alone. Mixed speeds will default to the lowest common frequency across all installed DIMMs.

Questions about this item

How do I confirm the 8GB DDR4 2666MHz ECC UDIMM is operating correctly after installation?

The system should POST and report the full 8GB capacity. Run a memory diagnostic tool to check for errors and verify the module is detected as ECC unbuffered at CL19.

What is included with the A-Tech 8GB DDR4 2666MHz ECC UDIMM and what must be purchased separately?

The box contains one 8GB DDR4 2666MHz ECC UDIMM module (1Rx8, 1.2V, CL19). No cables, brackets, or additional components are included.

Which version of the A-Tech 8GB DDR4 2666MHz ECC UDIMM should I choose for my HP server?

This module replaces HP part numbers L43768-001 and L36845-001. Select it if your system requires a 288-pin DDR4 2666MHz ECC unbuffered DIMM.
