Axiom 8GB DDR4-2666 ECC UDIMM cpu accessory

SKU CH-KBXD-Q3CKC

8 GB DDR4-2666 ECC UDIMM adds capacity for multitasking and error-correcting reliability in compatible systems

  • 8 GB capacity keeps more programs open simultaneously
  • DDR4-2666 speed delivers faster data rates for responsive loads
  • ECC UDIMM design provides enterprise-grade reliability and fault tolerance
  • DDR4 architecture reduces power consumption by 20% over DDR3
  • DDR4 scales up to 65% faster in 3-DIMM-per-channel configurations

Axiom 8GB DDR4-2666 ECC UDIMM

This 8 GB DDR4 module adds capacity for servers and workstations that require error-correcting memory. It targets system builders upgrading HP platforms using part number 879505-B21. The unbuffered DIMM suits single-CPU boards with UDIMM slots.

DDR4 interface limits and scaling

DDR4 delivers up to 30% better performance in single-DIMM configurations compared with DDR3. In three-DIMM-per-channel layouts the gain scales to 65% faster throughput. The standard reduces power draw by 20% while raising component densities by 300%. Signal integrity is improved over the previous generation.

Capacity headroom for multitasking

Eight gigabytes lets you keep more programs open simultaneously without swapping. The 2666 MT/s data rate feeds multi-threaded workloads and virtualisation hosts. Headroom shrinks when datasets exceed physical RAM or when channel population limits total installed memory.

Questions about this item

Should I pick the 8 GB DDR4-2666 ECC UDIMM or a different capacity for my HP server?

This module is an 8 GB DDR4-2666 ECC UDIMM built for HP part 879505-B21; choose it when your configuration calls for that exact capacity and speed.

What does the 2666 MT/s rating deliver once the DIMM is installed?

At 2666 MT/s the module can run up to 30 % faster than DDR3 in single-DIMM layouts and up to 65 % faster in three-DIMM-per-channel setups.

How does the DDR4 interface limit performance in practice?

DDR4 tops out at the rated 2666 MT/s on this UDIMM; the bus cannot exceed that data rate regardless of the processor or chipset.
