Server DDR4 module for registered ECC workloads

This 8 GB DDR4 stick runs at 2133 MT/s with a CL15 latency and 1.20 V operation. It uses a 288-pin form factor and includes on-die ECC with registered buffering for signal integrity. The single-rank 1Rx4 organisation suits density-optimised server boards.

Suits administrators expanding

The module requires a motherboard that supports registered ECC DDR4 and cannot be used in unbuffered consumer desktops or laptops. Systems limited to lower densities per slot or non-ECC memory will not accept this part.

Registered ECC with 1Rx4 rank structure

Registered buffering and ECC are mandatory for the target platform; the single-rank 1Rx4 layout determines how the memory controller addresses the 8 GB capacity. Verify that your server qualified-vendor list includes this configuration before purchase.

商品問答

How much power does the 1.20V DDR4 module draw when the server runs continuously?

The module operates at the standard DDR4 voltage of 1.20V; actual power draw depends on the server workload and platform power management.

What motherboard slot and chipset support is required for this 288-pin registered ECC module?

It requires a 288-pin DDR4 DIMM slot on a server or workstation platform that supports registered ECC memory.

Can this CL15 2133 MT/s stick run alongside older DDR4 modules at different speeds?

Yes, the motherboard will clock all installed DDR4 modules to the lowest common speed and latency.
