OWC 16GB DDR3-1600 ECC Registered RDIMM 2Rx4 1.5V Dell 370AAGI A5940905 A5940906 A6996807 CPAJDF1M server RAM

Server-grade DDR3 ECC RDIMM

This 16GB DDR3-1600 module is an ECC registered DIMM built for workstations, servers, NAS systems and routers. It replaces Dell part numbers 370AAGI, A5940905, A5940906, A6996807 and CPAJDF1M with identical JEDEC-standard specifications. The 2Rx4 organisation and CL11 latency suit multi-socket platforms that require registered memory. It will not operate in standard desktop computers.

Compatibility checklist before ordering

Verify that your platform accepts DDR3 ECC registered RDIMMs at 1.5V and uses 240-pin slots. Registered memory cannot be mixed with unbuffered modules, so confirm all installed sticks share the same registered type. Check the system documentation for maximum capacity per slot and total supported memory. Ensure the motherboard or controller supports PC3-12800 speed and CL11 timing without requiring a different voltage.

Build integration and capacity planning

Each module adds 16GB of error-correcting memory to a registered channel, freeing non-ECC slots for other uses. The lack of a heat spreader keeps the profile low for dense server chassis. Population rules vary by platform, so follow the vendor's slot-filling order to enable multi-channel operation. This module extends the service life of existing DDR3 infrastructure or provides a cost-effective upgrade path for new compatible builds.
