8GB DDR4-2133 ECC Registered Module

This 8 GB DDR4-2133 module provides ECC registered memory for servers and workstations that require error correction and signal buffering. It operates at 1.2 V with a CAS latency of CL15 and uses a 1Rx4 organisation. The 288-pin form factor fits standard DDR4 DIMM slots in compatible platforms.

Practical limits of DDR4-2133

The DDR4-2133 standard caps the data rate at 2133 MT/s, which limits peak bandwidth compared with faster DDR4 grades. Registered buffering adds one clock cycle of latency, and the single-rank x4 layout restricts the number of modules a memory controller can address per channel. Systems that demand higher throughput or greater capacity per channel will not reach their targets with this specification.

Installation notes

Align the module key with the slot notch and press firmly until both retention clips engage; the registered design does not change the physical insertion process. Common issues include mixing registered and unbuffered DIMMs, populating slots in an order the motherboard manual does not support, or exceeding the platform’s maximum rank count per channel. Verify the server’s qualified vendor list before installation.

Questions sur cet article

Should I choose the 8 GB 1Rx4 module or look for a different capacity?

This module provides 8 GB in a single-rank x4 organisation; select it when your server requires exactly that density and rank configuration.

What does the 2133 MHz speed deliver once installed in a server?

The DDR4 2133 rating (PC4-17000) sets the maximum data rate the module will run at when the platform supports that speed.

How does the registered DDR4 interface affect compatibility and performance limits?

The 288-pin registered DDR4 design adds a buffer that reduces electrical load on the memory controller, allowing higher capacities per channel while operating at 1.2 V.
