32 GB DDR5 4800 Desktop Module

This HP 4M9Y2AA module provides 32 GB of DDR5 memory rated at 4800 MT/s with a CAS latency of CL40. It operates at the standard 1.10 V for DDR5. The stick is a single 32 GB UDIMM intended for desktop platforms that accept DDR5 memory.

Builders who need 32 GB in one slot

The single-module layout suits systems with limited DIMM slots or users who want to leave room for future expansion. Buyers who require higher speeds, lower latency timings, or multi-module kits for dual-channel bandwidth should consider other options.

32 GB single-module capacity

The 32 GB density on a single UDIMM is the specification that determines whether this part fits the upgrade plan. Systems limited to lower per-slot densities or configurations that demand matched pairs will not be able to use this module as intended.
