Server memory for registered ECC platforms

This 8 GB DDR4 module operates at 2933 MT/s and carries ECC with registered buffering. It targets administrators who need reliable capacity for supported server or workstation boards.

288-pin DDR4 form factor

The 288-pin design fits standard DDR4 slots while the registered architecture reduces electrical load on the memory controller. That arrangement helps maintain stability when multiple modules populate a channel.

Replaces non-ECC or unbuffered DDR4 in qualified

The jump is worth it when the platform requires registered ECC memory for data integrity or for populating all available slots. Boards that accept only unbuffered modules cannot use this part.

Questions about this item

What bandwidth does the DDR4 2933 (PC4 23400) interface provide in practice?

The PC4 23400 rating means the module is specified for a peak transfer rate of 23400 MB/s when the platform runs it at 2933 MT/s.

Will the 288-pin DDR4 form factor and registered design fit my server board?

It uses the standard 288-pin DDR4 DIMM layout, but the registered buffer and ECC logic require a motherboard that explicitly supports registered ECC memory.

What is the correct way to install this 2Rx4 registered module, and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips lock, and ensure the BIOS is set to run the memory at 2933 MT/s rather than a lower default speed.
