32 GB DDR4 2666 Registered ECC Module

This 32 GB DDR4 2666 registered ECC DIMM is built for servers and workstations that require error-correcting memory and registered signal integrity. It suits administrators expanding memory in qualified platforms that specify PC4-21300 registered modules.

Registered Signal and DDR4 2666 Limits

Registered buffering adds one clock cycle of latency and requires a motherboard with registered DIMM support; unbuffered consumer boards will not accept it. The DDR4 2666 interface caps throughput at the PC4-21300 rate, so systems needing higher bandwidth must use a faster memory standard.

32 GB Single-Module Capacity

The module provides 32 GB in a single 288-pin DIMM, letting you reach large per-slot capacities without populating every slot. Buyers who need more total memory than the board's maximum supported capacity allows should verify the platform limit before purchasing.

Questions about this item

Should I choose the 32 GB module or combine smaller sticks for my server?

This 32 GB DDR4-2666 registered DIMM delivers the full capacity in a single slot, leaving room for future expansion without mixing ranks.

What does the 2666 MHz rating actually deliver inside a running server?

At 2666 MHz with CL19 latency the module provides up to 21300 MB/s bandwidth, letting heavy workloads move data quickly through each 2Rx4 rank.

How does the 288-pin DDR4 registered interface limit real-world performance?

The registered 288-pin DDR4 link caps transfer rate at 2666 MHz and requires a server platform that supports registered ECC memory for stable operation.
