8 GB DDR5 desktop module

This OWC module delivers 8 GB of DDR5 memory at 4800 MT/s for desktop systems. It is an unbuffered, non-ECC DIMM built to JEDEC and RoHS standards for a warranty-safe upgrade.

PC5-38400 CL40 at 1.1 V

The key specification is DDR5 4800 (PC5-38400) with CAS latency 40 running at 1.1 V. If your platform requires that exact speed, latency and voltage combination, this is the correct part.

Tool-free DIMM installation

Align the notch on the 288-pin edge connector with the motherboard slot and press down until the retention clips click. The most common issue is seating the module incompletely, which prevents the system from posting.

Questions about this item

What does 4800 MT/s DDR5 mean for my desktop?

The module runs at 4800 MT/s, the base JEDEC speed for DDR5, so it will operate at that rate on any compatible desktop board without manual tuning.

What does PC5-38400 tell me about the interface?

PC5-38400 is the JEDEC bandwidth designation for DDR5 4800; the DIMM uses the standard 288-pin unbuffered connector and 1.1 V signalling.

Will the 288-pin DIMM fit my motherboard slot?

Yes, it uses the standard 288-pin UDIMM keying used by desktop DDR5 boards; no heat spreader means it clears most CPU coolers.
