Single 8GB DDR5 4800 Module

This OWC UDIMM delivers 8GB of DDR5 memory at 4800 MT/s with a CAS latency of CL40. It operates at the standard 1.1V JEDEC voltage and uses an unbuffered, non-ECC 288-pin layout. The module is a direct upgrade for compatible desktop, workstation and all-in-one systems.

Compatibility Guidance

Suits owners of DDR5 platforms that accept 4800 MT/s JEDEC UDIMMs and need a single 8GB stick. Not for laptops or small-form-factor boards that require SO-DIMMs. Avoid if your system demands ECC, registered modules, speeds above 4800 MT/s or capacities beyond 8GB per slot.

Deciding Specification

The 4800 MT/s JEDEC speed rating is the single figure that determines fit. Your motherboard must support DDR5 4800 unbuffered non-ECC UDIMMs at 1.1V; otherwise the module will not function. Verify the board’s qualified vendor list before purchase.

Highlights

  • Boost responsiveness with 8 GB DDR5 4800 speed
  • Lower power draw at 1.1 V standard voltage
  • Easy DIY upgrade using 288-pin UDIMM form factor
  • Reliable operation backed by JEDEC compliance
  • Expand multitasking capacity for desktop and workstation use

Questions about this item

Does the box contain only the single 8 GB DDR5 UDIMM or are extra parts included?

The package contains one 8 GB DDR5 4800 CL40 1.1 V unbuffered 288-pin UDIMM with no heat spreader and no additional accessories.

How do I decide between this 8 GB module and a larger capacity kit?

Choose this single 8 GB stick when adding to an existing DIMM or filling one slot; select a multi-module kit when you need more total capacity or want to populate multiple channels.

What does the 4800 MT/s rating deliver in a real desktop?

The JEDEC-standard 4800 MT/s speed runs at 1.1 V with CL40 latency, giving baseline DDR5 bandwidth for everyday desktop, workstation or NAS workloads.
