32GB DDR5 5600 desktop kit

This OWC kit supplies 32 GB of DDR5 memory in a matched pair of 16 GB UDIMMs. It runs at 5600 MT/s with CL46 latency at the standard 1.1 V JEDEC voltage. The modules are unbuffered, non-ECC and built for desktop, workstation, NAS and all-in-one systems.

JEDEC DDR5 5600 baseline

The kit operates at the JEDEC-defined DDR5-5600 speed grade with CL46 timings and 1.1 V. No XMP or EXPO profiles are present, so the memory will only run at this validated baseline. Systems that cannot boot at DDR5-5600 will fall back to a lower JEDEC speed if the platform supports it.

Motherboard DDR5 UDIMM support

Verify that your board accepts 288-pin DDR5 UDIMMs and can run 1Rx8 modules at the JEDEC 5600 MT/s rate. Check the vendor’s qualified-vendor list for 32 GB dual-rank kits and confirm the BIOS is current enough to initialise DDR5 at the standard voltage.

Questions about this item

Should I choose the 32 GB dual-channel kit or a single 16 GB module for my desktop?

The 32 GB kit contains two matched 16 GB modules that run together in dual-channel mode, doubling memory bandwidth compared with a single stick.

What does the DDR5 5600 CL46 rating deliver in everyday use?

The memory operates at 5600 MT/s with a CAS latency of 46 cycles, giving fast data rates for multitasking and large-file workloads.

How does the PC5-44800 designation limit performance on my motherboard?

PC5-44800 is the JEDEC standard name for DDR5 5600; the modules will run at that speed unless the motherboard forces a lower rate.
