Server ECC RDIMM
This 32GB DDR4 2666 CL19 module is a registered ECC RDIMM built for servers, workstations and NAS systems. It runs at 1.2V with a 2Rx4 rank layout on a 288-pin interface. The part is designed as a direct replacement for QNAP part RAM-32GDR4ECK0-RD-2666 and meets JEDEC and RoHS standards.
Replaces slower DDR4
The module upgrades existing 2133MHz or 2400MHz DDR4 ECC registered memory while maintaining full backward compatibility. The jump is worth it when your workload needs the higher 2666MHz data rate and 21300 bandwidth to reduce latency in multi-threaded server tasks. It will not work in standard desktop computers and cannot be mixed with unbuffered DIMMs.
Fits registered memory slots
Installation requires a platform that supports DDR4 ECC registered RDIMMs with 288-pin slots and 1.2V operation. The module frees up capacity headroom for virtualisation, large datasets or ZFS caches without adding heat spreaders that could conflict with tight server chassis spacing. Verify your system manual for maximum supported capacity per slot and total population rules.

Questions about this item
Does the 288-pin DDR4 RDIMM fit a standard server DIMM slot?
Yes, the module uses the standard 288-pin DDR4 RDIMM form factor for server and workstation motherboards.
What BIOS setting is often missed when installing this ECC registered memory?
Enable ECC and registered memory support in the BIOS; the system will not recognise the module if those options remain disabled.
Will the 1.2V modules need active cooling or replacement fans over time?
No, the modules run at 1.2V without a heat spreader and have no moving parts, so no cooling maintenance or replacement is required.
