OWC 64GB DDR3 1600 Kit

This OWC kit supplies 64GB of DDR3 memory across four 16GB unbuffered DIMMs. Each module runs at 1600MHz with CL11 latency at the standard 1.5V JEDEC voltage. The 240-pin desktop form factor fits compatible workstation and PC platforms.

Thermals and Power Draw

Operating at the JEDEC 1.5V specification keeps power consumption within standard DDR3 limits for desktop DIMMs. No heat spreaders are fitted, so the modules rely on normal case airflow for cooling. The design targets silent operation with no active cooling required.

JEDEC Compliance and Support

Full JEDEC and RoHS compliance ensures a warranty-safe upgrade that meets OEM specifications. OWC validates every module in its own lab and backs the kit with a limited lifetime warranty plus free technical support. An online installation video assists the DIY fitting process.

Questions about this item

Will this kit fit a standard desktop motherboard with four DDR3 DIMM slots?

Yes, the kit contains four 240-pin DDR3 UDIMMs that install in standard desktop DDR3 slots.

Does the 1.5 V rating match the JEDEC standard for DDR3 so I do not need to change BIOS voltage settings?

The modules run at the JEDEC-standard 1.5 V, so most boards will configure them automatically without manual voltage changes.

Can I use this memory in a dual-channel motherboard that only supports two modules per channel?

The four-module kit is designed for dual-channel operation; populate all four slots to run in dual-channel mode.
