16 GB registered DDR4 module

This 16 GB DDR4-3200 DIMM uses a registered 2Rx8 layout for server platforms that require registered memory. It operates at CL19 latency without ECC error correction. The module fits standard 288-pin DDR4 slots.

DDR4-3200 speed ceiling

The PC4-25600 rating sets the maximum data rate at 3200 MT/s on a DDR4 bus. Systems limited to lower DDR4 speeds will downclock the module automatically. Boards that only accept unbuffered DIMMs cannot use this registered stick.

Registered 2Rx8 organisation

The dual-rank 2Rx8 registered design targets multi-slot server boards qualified for registered memory. Workstations or consumer boards that require unbuffered modules will not accept this part.

Questions about this item

Is the 16 GB 2Rx8 registered module the right choice for a dual-CPU server that needs registered memory?

Yes, the 16 GB 2Rx8 registered DIMM is designed for multi-socket servers that require registered memory and fits a single 288-pin slot.

What does the DDR4-3200 PC4-25600 rating deliver in a compatible server?

It provides a 3200 MT/s data rate with CL19 latency, giving 25600 MB/s peak bandwidth per module when the platform runs at the rated speed.

Does the 288-pin DDR4 registered interface limit the usable speed on older DDR4 platforms?

The module runs at up to 3200 MT/s on platforms that support DDR4-3200 registered memory; on older DDR4 platforms it will operate at the highest speed the platform allows.
