Axiom

Axiom 8GB DDR4-2666 ECC RDIMM for Apple

SKU CH-68WN-7AKHN

An 8 GB DDR4-2666 ECC RDIMM module that adds registered, error-correcting memory to compatible Apple systems

  • ECC protection safeguards data integrity in critical workloads
  • DDR4 architecture delivers up to 30% faster single-DIMM performance
  • Registered design with 288-pin interface ensures signal stability
  • Lower voltage cuts power draw by about 20%
  • 3-DIMM-per-channel scaling reaches up to 65% speed gain over DDR3

Axiom 8GB DDR4-2666 ECC RDIMM

This Axiom module is an 8 GB DDR4-2666 ECC RDIMM built for compatible Apple systems. It uses a 288-pin DDR4 SDRAM interface to synchronise electrical and clock signals for stable data transfer. The registered design adds a buffer that helps maintain signal integrity on heavily populated memory channels.

Suits Macs needing registered ECC memory

Workstations and servers that require registered DIMMs with error-correcting code will benefit from the fault-tolerance and RAS features this module provides. Systems limited to unbuffered non-ECC memory cannot use this RDIMM, so buyers needing standard consumer SO-DIMMs or UDIMMs should look elsewhere.

Fits 288-pin DDR4 RDIMM slots

Installation requires a motherboard or logic board with 288-pin DDR4 RDIMM slots that support ECC operation. The lower voltage of DDR4 reduces power draw compared to DDR3, which eases cooling demands and leaves more thermal headroom for other components in the chassis.

Questions about this item

Does this 288-pin DDR4 RDIMM need an Apple Mac Pro with DDR4 slots to work?

Yes, the module uses a 288-pin DDR4 SDRAM interface and is built for Apple systems that accept DDR4 RDIMMs, so the host must provide compatible DDR4 memory slots.

Can I mix this 2666 MT/s ECC RDIMM with existing DDR3 modules in the same machine?

No, DDR4 and DDR3 use different pin layouts and signalling, so they cannot be installed together; the system must run either all DDR4 or all DDR3 memory.

How can I confirm the DIMM is running at 2666 MT/s with ECC active after installation?

Check the memory speed and ECC status in macOS System Report or run a memory diagnostic that reports the operating data rate and error-correction state.
