16 GB DDR3 ECC RDIMM for servers

This 16 GB DDR3 1066 MHz registered DIMM delivers error-correcting memory for server and workstation platforms. The 4Rx4 organisation and 1.50 V operation suit systems that require PC3-8500 registered modules. A 240-pin form factor fits standard DDR3 DIMM slots.

Replaces Dell A3721495 and A3721501 modules

The module matches the Dell A3721495 and A3721501 part numbers for direct replacement in compatible Dell servers. Upgrading makes sense when the existing configuration uses smaller-capacity registered DIMMs and the platform supports 16 GB per slot. Systems already populated with maximum supported memory will not benefit.

Verify registered DIMM support

Confirm the motherboard or server chassis accepts DDR3 registered ECC memory before ordering. Check the maximum supported capacity per slot and the allowed rank population for your specific model. Ensure the platform operates at 1.5 V DDR3 voltage and can address 4Rx4 modules.

Questions about this item

Will the 240-pin DDR3 DIMM fit my server's memory slots?

This module uses the standard 240-pin DDR3 DIMM form factor, so it fits any server or workstation slot designed for DDR3 registered memory.

What is the correct way to seat this registered ECC module, and what step is often missed?

Align the notch with the slot key, press firmly until both side clips click shut, and verify the system recognises the full 16GB capacity and ECC function in BIOS.

When will this 16GB DDR3 1066MHz module need replacement?

DDR3 server memory has no scheduled replacement interval; it runs at 1.5V and is tested for lifetime reliability, so it stays in service until a capacity upgrade or platform change.
