128GB DDR5 4800 ECC Registered Server Memory

This 128GB DDR5-4800 module is built for Dell servers that require ECC registered memory. It uses a 4Rx4 organisation to deliver high capacity in a single slot. The module suits administrators upgrading or repairing compatible Dell platforms.

DDR5-4800 Registered ECC Interface Limits

The DDR5-4800 standard sets the maximum data rate and the registered buffer adds one cycle of latency. ECC protection corrects single-bit errors but does not increase bandwidth. Capacity per module is capped by the 4Rx4 density and the memory controller's rank limit.

Replaces Dell MMWR9 for Capacity Upgrades

This module directly replaces the Dell MMWR9 part number in supported systems. The jump is worthwhile when the server needs more memory per slot than smaller RDIMMs provide. It is not for systems that only accept unbuffered UDIMMs or lower-density registered modules.

Questions about this item

Should I pick the 128GB 4Rx4 version or a smaller capacity for my Dell server?

The 128GB 4Rx4 module delivers maximum density per slot; choose it when your Dell platform supports 4Rx4 registered DIMMs and you need the highest capacity in the fewest slots.

What does the DDR5-4800 PC5-38400 rating mean once the module is installed in a live server?

The module runs at 4800 MT/s, providing 38400 MB/s peak bandwidth per DIMM; actual throughput depends on the CPU memory controller and the number of populated channels.

How does the DDR5 registered ECC interface affect compatibility and performance limits?

The registered ECC DDR5 interface adds a register buffer for signal integrity and error correction, allowing large-capacity 4Rx4 modules to operate reliably within the server memory controller specifications.
