Capacity and configuration

This OWC kit delivers 32GB of DDR3 memory in a four-module pack of 8GB each. It runs at 1600MHz with a CAS latency of 11 and operates at the standard 1.5V. The unbuffered, non-ECC DIMMs use the 240-pin form factor required by desktop and workstation platforms.

Who this suits and who should look elsewhere

The kit targets owners of desktop or workstation systems that accept DDR3 PC3-12800 modules and have four available slots. It is not suitable for laptops, servers requiring registered or ECC memory, or any platform built for a different DDR generation.

Deciding specification

The memory technology is DDR3; the modules will only fit and function in motherboards designed for that generation. Verify your board supports DDR3 1600 unbuffered non-ECC DIMMs before purchase.

Questions about this item

How can I confirm the kit is running at 1600 MHz with CL11 after installation?

Enter the BIOS or UEFI and verify the memory frequency reads 1600 MHz and the CAS latency shows 11. CPU-Z or a similar tool inside the OS will display the same figures.

What does the 32 GB kit contain and is anything else required?

The kit includes four 8 GB DDR3 UDIMM modules. No extra cables, brackets or software are needed; install them directly into the motherboard DIMM slots.

Why choose the 32 GB (4×8 GB) version over a smaller capacity?

The 32 GB kit provides the maximum density for four-slot desktop boards that support 8 GB DDR3 modules, giving the highest total memory without mixing capacities.
