OWC 32GB DDR4 2400 Kit

This kit contains two 16GB unbuffered UDIMM modules built to the DDR4 2400 standard. It targets desktop owners who want a straightforward capacity increase for everyday multitasking and larger workloads.

JEDEC DDR4 2400 limits

The modules run at the JEDEC‑defined 2400 MT/s rate with CL17 timing at 1.2V. That specification caps peak bandwidth at the PC4‑19200 level, so the memory cannot exceed this throughput regardless of motherboard capabilities.

Tool‑free DIMM installation

Each stick inserts into a standard 288‑pin slot and locks with the board’s retention clips. Common issues are seating the module off‑centre, mixing kits with different timings, or leaving the BIOS at a lower default speed until XMP or manual adjustment is applied.

Questions about this item

Should I pick the 32GB dual-channel kit or buy a single 16GB module instead?

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

What does DDR4 2400 CL17 mean for everyday desktop performance?

It runs at 2400 MT/s with a CAS latency of 17 cycles, giving responsive multitasking and smooth handling of larger files at standard JEDEC voltage.

Does the 288-pin UDIMM interface limit the speed I can actually reach?

The 288-pin unbuffered DIMM follows the JEDEC DDR4 2400 specification, so the module operates at its rated 2400 MT/s without manual overclocking.
