HPE 16GB Single Rank x8 DDR5-4800 Unbuffered Standard Memory Module

The HPE P64336-B21 is a 16 GB DDR5 memory module that lets you expand the capacity and speed of compatible HPE servers without stretching your budget. Designed for standard use, it delivers 4800 MT/s data rates, so everyday workloads such as virtualization, file sharing, and database queries finish faster and with greater efficiency.

This module uses a single-rank configuration with x8 DRAM devices, which helps maintain clean signal integrity for stable performance, even when multiple DIMMs are installed. Because it is unbuffered, you can plug it directly into entry-level or edge servers that do not require registered memory, keeping deployment straightforward and cost-effective.

HPE puts each module through a full qualification process to make sure it aligns with platform specifications and long-term reliability standards. The 1.2-volt operating level supports lower power consumption, an advantage for businesses that run servers around the clock and want to keep energy costs in check.

Whether you are upgrading a single ProLiant tower for a growing team or building out a rack of edge systems for remote offices, this 16 GB DIMM provides the headroom needed for additional virtual machines, larger data sets, and smoother multitasking. Install it to give your server the balanced mix of capacity and speed required for modern small and midsize business workloads.
