Server DDR5 module for registered ECC workloads

This 16 GB DDR5 DIMM runs at 4800 MHz with CL40 latency and 1.10 V operation. It is built for servers and compute modules that require registered memory with error correction. The 288-pin form factor fits standard DDR5 server slots. Buyers needing unbuffered consumer memory or non-ECC modules should look elsewhere.

Registered ECC with 1Rx8 organisation

The module uses a single-rank 1Rx8 layout and registered buffering to reduce electrical load on the memory bus. ECC capability detects and corrects single-bit errors for data integrity. CL40 timing at DDR5-4800 provides the specified throughput. Systems that do not support registered ECC DDR5 cannot use this part.

No heat spreader or extra software included

The DIMM ships without a thermal spreader, relying on system airflow for cooling. No configuration utilities, firmware tools or licensing bundles are supplied. Installation is a physical memory upgrade only; compatibility depends on the platform memory controller and BIOS support for registered ECC DDR5.

Questions about this item

What does the 4800 MHz speed actually deliver in a live server?

The module runs at DDR5-4800 with CL40 latency, giving a peak bandwidth of PC5-38400 while the registered buffer keeps signal integrity stable across full DIMM populations.

How does the DDR5 interface and registered design limit real-world throughput?

DDR5-4800 sets the maximum data rate at 4800 MT/s; the registered clock driver adds one cycle of latency but allows the memory controller to drive more DIMMs per channel without signal degradation.

What physical slot and clearance does this 288-pin DIMM need?

It requires a standard DDR5 288-pin DIMM socket; the module has no heat spreader, so it fits in tight server chassis where taller registered DIMMs would interfere with airflow or CPU coolers.
