SKU CH-DSYG-GTJCJ MPN MP1866R/64GK-AX

Provides 64 GB of registered ECC desktop memory at 1866 MHz PC3-14900 in a dual-rank kit

  • 64 GB total capacity for memory-intensive workloads
  • 1866 MHz data rate supporting PC3-14900 bandwidth
  • Registered ECC design for error-correcting reliability
  • Dual-rank organisation maximising module density
  • System-specific validation for guaranteed compatibility

Kit contents and purpose

This Axiom MP1866R/64GK-AX kit supplies 64 GB of registered ECC desktop memory rated at 1866 MHz PC3-14900. Each module is built with tier-one components and tested for guaranteed compatibility inside supported systems. The dual-rank design suits workloads that demand error correction and data integrity.

Suitable buyers and mismatched needs

System integrators and IT teams who require qualified, server-grade reliability for mission-critical desktops or workstations will fit this kit. Buyers who need non-ECC unbuffered memory for standard consumer platforms or who require capacities beyond 64 GB should look at different memory configurations.

Deciding specification

The registered ECC architecture is the single attribute that determines whether this kit matches the target motherboard and chipset. Only systems designed for registered error-correcting modules at 1866 MHz PC3-14900 can use this memory.

Questions about this item

Does this 64 GB kit require a motherboard that supports registered ECC memory?

Yes, the modules are built as registered ECC DIMMs, so the board must accept registered error-correcting memory for the kit to function.

Can the 1866 MHz modules run in a system that currently uses slower memory?

The kit is rated at 1866 MHz PC3-14900; when installed alongside slower modules the system will typically clock all memory down to the lowest common speed.

How can I verify the full 64 GB is recognised after installation?

Check the system BIOS or UEFI memory summary and the operating system task manager — both should report 64 GB total capacity at the rated 1866 MHz speed.
