32GB DDR4 2666MHz Desktop Kit

This OWC kit provides 32GB of DDR4 memory across four 8GB unbuffered UDIMMs. It is built for desktop PCs, workstations and NAS systems that accept standard 288-pin modules. The CL19 latency and 1.2V operation match common platform requirements for a straightforward capacity upgrade.

JEDEC DDR4 2666MHz Standard Limits

The modules run at the JEDEC DDR4 2666MHz (PC4-21300) specification with CL19 timing. They are backward compatible with 2133MHz and 2400MHz bus speeds, so they will operate at the highest common frequency the motherboard supports. No heat spreaders are fitted, keeping the modules low-profile for tight slots.

Four-Module 32GB Capacity Decision

The kit delivers 32GB in a 4x8GB configuration, which populates four DIMM slots in dual-channel mode. Buyers must confirm their board has four free slots and supports 32GB total capacity at 2666MHz. The 288-pin DDR4 form factor is the single specification that determines physical fit.

商品問答

Will this kit fit a motherboard with four 288-pin DDR4 slots?

Yes, the kit contains four 288-pin UDIMM modules designed for standard desktop DDR4 slots.

Can I use these modules in a system that currently runs 2133MHz or 2400MHz memory?

The modules are backward compatible with 2133MHz and 2400MHz speeds and will run at the lower frequency automatically.

Is this memory suitable for a non-ECC desktop or workstation board?

Yes, these are non-ECC unbuffered DIMMs made for desktop PCs, workstations and compatible NAS systems.
