Dual-channel DDR4 kit

This OWC kit supplies eight gigabytes of DDR4 memory as two matched four-gigabyte modules. It is built for desktop PCs, workstations and NAS systems that accept standard UDIMMs. The unbuffered, non-ECC design suits mainstream consumer and small-business platforms.

2133 MT/s CL15 at 1.2 V

The modules run at 2133 MT/s with a CAS latency of 15 and operate at the JEDEC-standard 1.2 volts. Each stick uses a single-rank 1Rx8 organisation and fits 288-pin DDR4 slots without requiring a heat spreader.

No extra accessories or software

The package contains only the two memory modules themselves. There are no bundled tools, cables, configuration utilities or licensing codes that would alter installation or system behaviour.

Questions about this item

What real-world speed does the DDR4 2133 rating deliver once the kit is installed?

The modules run at 2133 MT/s with CL15 timing, giving a peak bandwidth of PC4-17000 that the memory controller will use automatically.

How does the PC4-17000 standard limit performance on a typical desktop board?

PC4-17000 caps the data rate at 2133 MT/s, so the kit will not run faster even if the motherboard supports higher DDR4 speeds.

Will the 288-pin unbuffered DIMMs fit a standard desktop motherboard slot?

Yes, each 288-pin UDIMM matches the regular desktop DIMM slot and requires no heat spreader clearance.
