32GB DDR3 1866 ECC Registered Kit

This 32GB kit contains two 16GB modules built to the DDR3 1866 (PC3 14900) standard with a CAS latency of CL11 and 11-11-11-14 timings. Each stick uses a 240-pin form factor and features ECC Registered (buffered) architecture with a 2Rx4 rank configuration. It is designed for server platforms that specifically require registered DDR3 memory with error correction.

Suited for DDR3 registered server upgrades

The modules target administrators upgrading or repairing systems that accept 240-pin DDR3 RDIMMs at 1866 MT/s with ECC and registered signalling. Builders working with consumer desktop boards, laptops, or any platform that only supports unbuffered non-ECC memory cannot use this kit. Buyers needing different capacities, speeds, or rank organisations must select an alternative part.

Registered ECC with 2Rx4 organisation

The registered buffer and ECC functionality are the decisive specifications; they determine whether the memory is electrically compatible with the target server memory controller. Systems that require unbuffered UDIMMs or load-reduced LRDIMMs will not accept these RDIMMs, so verifying the motherboard's supported module type is essential before purchase.

Questions about this item

Will the 240-Pin DDR3 modules fit my server's DIMM slots?

Yes, each stick uses the standard 240-Pin DDR3 form factor used by registered DDR3 server boards.

Do I need to populate specific channels for the 2Rx4 registered DIMMs to initialise?

Install the pair in matching channel slots (usually same-coloured banks) so the memory controller sees both ranks per channel.

How can I tell when a 16 GB ECC registered module should be replaced?

Run a full memory diagnostic at each maintenance window; replace any stick that logs corrected or uncorrected ECC errors.
