ECC Registered DDR3 Server Memory Kit

This OWC kit supplies 64GB of DDR3 ECC registered memory across eight 8GB modules. Each DIMM runs at 1600MHz with CL11 latency and operates at 1.5V. The 240-pin RDIMM form factor is built for workstations and servers that require registered, error-correcting memory.

Compatibility and Usage Limits

Suitable for administrators upgrading compatible workstations, servers, NAS systems or routers that accept DDR3 ECC registered RDIMMs. Not suitable for standard desktop PCs, laptops or any platform that uses unbuffered memory, as registered modules will not function in those systems.

Deciding Specification — Registered ECC DDR3

The modules are DDR3 ECC registered RDIMMs; this single attribute determines fitment. Only systems explicitly designed for registered error-correcting DDR3 can use this kit.

Questions about this item

What does the DDR3 1600 PC3-12800 rating cap in practice?

The kit runs at 1600 MHz with a maximum bandwidth of PC3-12800 and CL11 latency, so throughput is limited to that JEDEC standard.

What physical slot and form factor does this 240-pin RDIMM need?

Each module is a 240-pin DDR3 ECC Registered DIMM that fits only server or workstation boards with matching registered DIMM slots.

How is the 8-module kit installed and what step is often missed?

Install all eight 8 GB sticks in the correct channel order for the platform; the step often missed is verifying the board requires registered ECC memory and cannot accept unbuffered DIMMs.
