8GB DDR4 ECC RDIMM for Servers

This 8GB DDR4 2666MHz ECC RDIMM module is built for server and workstation systems that require registered memory with error correction. It operates at 1.20V with a CAS latency of CL19 and uses a 1Rx4 rank configuration on a 288-pin DIMM form factor. The module serves as a direct replacement for HP part Q7D79A.

Tested Reliability and US Support

Every module undergoes quality assurance testing to ensure dependable performance in compatible systems. The package includes a single 8GB stick with no additional accessories or software. A-Tech provides lifetime warranty coverage and United States based technical support for the product lifetime.

Suited for HP-Compatible Server Upgrades

This memory suits administrators upgrading HP servers that specify the Q7D79A part number and support DDR4 2666MHz ECC RDIMM modules. Builders needing unbuffered UDIMM memory, higher capacities per slot, or faster speeds should verify their platform requirements before purchasing.

Questions about this item

Will the registered ECC design require any firmware updates or periodic maintenance?

No firmware updates or periodic maintenance are required for the registered ECC module once it is installed and verified in a compatible server.

What thermal or power limit appears first when the module runs continuously at 2666 MHz?

The module operates at the standard 1.2 V DDR4 voltage, so power draw stays within the JEDEC specification and thermal limits are not reached under normal sustained loads.

How much heat and noise does the 288-pin DIMM add to a server running all day?

The DIMM itself has no moving parts and generates only modest heat at 1.2 V, adding no audible noise to the system.
