Server memory module

This is a 32GB DDR5 4800 registered DIMM with ECC and CL40 latency. It is built for enterprise servers and workstations that require error-correcting registered memory. Buyers who need unbuffered desktop modules or non-ECC memory should look elsewhere.

Registered ECC specification

The module operates as a single-rank 1Rx4 registered DIMM at 1.10V with CAS latency 40. This specific registered ECC configuration is the deciding factor for compatibility with server motherboards that require registered memory. Systems that accept only unbuffered DIMMs cannot use this module.

Standard 288-pin installation

Installation follows the usual 288-pin DDR5 DIMM procedure: align the notch, press firmly until the retention clips engage. Common issues arise when the platform expects unbuffered memory or a different rank configuration, causing the system to fail POST. Always verify the motherboard supports registered ECC DDR5 before fitting.

Questions sur cet article

What does the DDR5 4800 rating mean once the module is installed in a server?

The module operates at 4800 MT/s with CL40 latency, delivering the standard DDR5 4800 data rate when the platform runs memory at that speed.

How does the 288-pin DDR5 R-DIMM interface limit performance in practice?

The registered 288-pin DDR5 interface supports the 4800 MT/s data rate and ECC, and the registered buffer adds one cycle of address/command delay as per the DDR5 RDIMM specification.

What physical clearance does the 32 GB DDR5 module need to fit in a server chassis?

The module is a standard-height 288-pin DDR5 R-DIMM without a heat spreader, so it fits any slot that accepts full-height registered DDR5 DIMMs.
