8GB DDR4 ECC RDIMM for servers

This 8GB DDR4 ECC RDIMM module runs at 2133MHz with CL15 latency and 1.20V voltage. It uses a 1Rx4 rank configuration on Micron chipset and is built as a compatible replacement for specific Micron part numbers. The registered design targets server and workstation platforms that require error-correcting memory.

DDR4 2133 registered DIMM limits

The module operates at the DDR4 2133 standard (PC4-17000) with a fixed 1.20V supply and CL15 timing. Registered signalling adds one clock cycle of latency compared with unbuffered DIMMs, and the 1Rx4 organisation limits maximum density per channel on some platforms. Systems must support ECC RDIMM at this speed; they will not accept unbuffered or non-ECC modules in the same slots.

Check motherboard qualified-vendor list

Verify that your server or workstation motherboard lists the Micron part numbers shown in the specifications as supported memory. Confirm the platform accepts 288-pin DDR4 RDIMMs at 2133MHz with 1.20V operation and 1Rx4 rank layout. Populate slots according to the vendor's population rules for registered DIMMs to ensure the system posts correctly.

Questions about this item

Should I pick the 1Rx4 registered ECC module or look for a different rank for my server?

This module is a single 8 GB stick built as 1Rx4 registered ECC; choose it when your platform requires registered DIMMs with that rank configuration.

What does the 2133 MHz rating deliver once the DIMM is installed?

It runs at DDR4 2133 MHz with CL15 latency at 1.20 V, giving a PC4-17000 data rate for compatible server and workstation boards.

Does the 288-pin DDR4 interface limit the speed to 2133 MHz in practice?

The 288-pin DDR4 form factor supports higher speeds, but this module is specified at 2133 MHz and will operate at that frequency in a compatible system.
