16GB DDR4 3200 Registered ECC Module

This 16GB DDR4 3200 module delivers PC4 25600 bandwidth with CL22 22-22-22 timing at 1.20V. Registered design and ECC support target server platforms that require registered memory. The 2Rx8 organisation suits dual-rank channel populations.

Installation and Common Issues

Align the module key with the slot and press until the latches engage; registered modules will not fit unbuffered desktop slots. Mismatched registered and unbuffered DIMMs prevent boot. Mixing ranks or speeds can force the channel to the slowest common timing.

DDR4 3200 Practical Limits

DDR4 3200 caps transfer rate at PC4 25600 per module; total throughput depends on channel count and CPU memory controller. Registered buffering adds one cycle of command delay versus unbuffered DIMMs. Maximum capacity per channel is limited by the platform memory controller and qualified vendor list.

Questions about this item

How do I verify the module is running at DDR4 3200 with CL22 timing after installation?

Check the BIOS or a system utility such as CPU-Z; the memory should report 3200 MT/s, CAS latency 22, and timing 22-22-22 at 1.20 V.

What comes in the box and do I need any extra brackets or cables?

The package contains the 16 GB DDR4 3200 ECC Registered DIMM only; no brackets, cables or additional hardware are included.

Which capacity and rank should I choose for a dual-channel server board?

This is a single 16 GB 2Rx8 module; add a second identical module to populate both channels for optimal bandwidth.
