OWC 16GB DDR5 5600 Desktop Memory Module

This OWC module delivers 16GB of DDR5 memory rated at 5600 MT/s with a CL46 latency and 1.1V operating voltage. It uses a standard 288-pin unbuffered non-ECC UDIMM form factor in a black finish without a heat spreader. The single-rank 1Rx8 design targets desktop, workstation, NAS and all-in-one systems needing a straightforward capacity increase.

Suitable for Standard Desktop

This kit fits users who want a JEDEC-standard DDR5 upgrade for compatible desktops, workstations or NAS units without overclocking or RGB lighting. It is not intended for platforms that require ECC error correction, registered modules, lower CAS latencies, or voltages other than 1.1V.

5600 MT/s JEDEC Speed Rating Determines Fit

The decisive specification is the 5600 MT/s JEDEC speed grade paired with CL46 timing at 1.1V. Verify that your motherboard and CPU officially support this exact DDR5 data rate and voltage before purchase, as mismatched speeds will force the module to run at a lower standard frequency.

Questions about this item

Does the 5U6D51R816GB module ship as a single 16 GB stick or do I need to buy anything else to install it?

The package contains one 16 GB DDR5 5600 CL46 1.1 V 288-pin unbuffered non-ECC UDIMM. No extra parts or cables are required for installation in a compatible desktop slot.

How do I decide between this 16 GB 5600 CL46 kit and a higher-capacity or lower-latency alternative?

Choose this module when you need a single 16 GB JEDEC-standard DDR5 5600 stick at 1.1 V for a desktop, workstation, NAS or all-in-one that supports unbuffered non-ECC memory.

What does the 5600 MT/s rating actually deliver once the DIMM is seated in my system?

The module runs at the JEDEC-standard 5600 MT/s data rate with CL46 latency at 1.1 V, giving a PC5-44800 bandwidth rating that the memory controller will use automatically if the platform supports DDR5 5600.
