Server RAM for ECC workloads

This 16GB DDR4 2666 ECC RDIMM module is built for servers and workstations that require error-correcting registered memory. It runs at 1.2V with CL19 latency and a 1Rx4 rank configuration. The 288-pin DIMM fits standard DDR4 slots in compatible enterprise platforms.

Replaces non-ECC or lower-capacity sticks

The module serves as a direct compatible replacement for Crucial CT16G4VFS4266 memory. The jump is worth it when your system demands registered ECC buffers for data integrity and you need to move beyond unbuffered consumer DIMMs or smaller 8GB modules.

16GB capacity with single-rank headroom

The 16GB density handles typical virtualization hosts, database nodes and multi-user application servers without filling every slot. Headroom narrows when workloads exceed per-channel capacity limits or when the platform requires dual-rank or higher-density modules for maximum throughput.

Perguntas sobre este artigo

Does this DDR4 module use a 288-pin DIMM form factor?

Yes, it is a 288-pin DDR4 DIMM designed for server and workstation motherboards that accept registered memory.

How do I install this registered ECC module correctly?

Align the notch on the 288-pin edge connector with the slot key, press firmly until the retention clips click, and ensure the motherboard supports registered ECC RDIMMs.

Will the 1.20V voltage require any future adjustment or replacement?

No, 1.20V is the standard DDR4 operating voltage; the module runs at this level for its lifetime with no user maintenance needed.
