HPE Compatible 8GB DDR4-2666 ECC

This registered ECC module delivers 8 GB of DDR4-2666 memory for HPE servers that require PC4-21300 speed and 1.20 V operation. The 1Rx4 organisation and 288-pin form factor match the Q7D79A part number for direct replacement in supported platforms.

Third-party validated compatibility

Brute Networks uses major-brand DRAM from Samsung, SK Hynix or Micron and validates every module at 100 % test coverage. Identical modules ship together so mixed-rank or mixed-vendor issues do not appear during installation or later firmware updates.

DDR4-2666 registered ECC limits

Registered ECC buffers each command cycle, adding latency that benefits stability over raw throughput. The 2666 MT/s ceiling caps bandwidth for workloads that scale with memory speed, and the fixed 1.20 V prevents manual voltage tuning for higher frequencies.

Questions about this item

Will the 8 GB DDR4-2666 module need any replacement or maintenance after installation?

The module is a solid-state component with no moving parts and carries a lifetime warranty, so no scheduled maintenance or replacement is required under normal server operation.

What limit appears first when the registered ECC stick runs continuously at its rated 2666 MT/s speed?

The registered buffer and ECC logic operate within the JEDEC 1.20 V specification, so the electrical and signal-integrity margins of the DDR4 interface define the sustained-use boundary.

How much heat and power does the 1.2 V 1Rx4 DIMM produce during all-day operation?

At the standard 1.20 V DDR4 voltage the 8 GB module draws only a few watts, generating minimal heat that is easily handled by normal server airflow.
