16 GB DDR5 ECC UDIMM for servers

This module adds 16 GB of DDR5 memory with error-correcting code and unbuffered operation. It is designed for servers and workstations that require data integrity and standard DIMM form factor. The part carries Dell part number AC958788 and ships as a single stick. Buyers who need registered or load-reduced DIMMs cannot use this module.

Speed rating DDR5-4800 PC5-38400

The memory runs at 4800 MT/s with a PC5-38400 bandwidth rating. This speed is the single specification that determines compatibility with the platform memory controller. Systems configured for a different DDR5 data rate will not operate correctly with this module.

Capacity headroom for mainstream workloads

Sixteen gigabytes suits typical virtualization hosts, database nodes and application servers running moderate datasets. Workloads that scale beyond this capacity per slot will require higher-density modules or additional populated channels.

Questions about this item

What does the 4800 MT/s rating mean once this module is installed in a server?

The module runs at 4800 MT/s, delivering PC5-38400 bandwidth for DDR5 workloads.

How does the DDR5 interface and ECC UDIMM design affect usable performance?

DDR5 provides the electrical interface; ECC UDIMM adds error correction without a register, so the memory controller sees 4800 MT/s directly.

What physical slot and clearance does this 16 GB DIMM require?

It fits a standard DDR5 UDIMM slot; the single-rank 1Rx8 layout uses the normal DIMM height.
