16 GB DDR3 ECC Registered DIMM

This HP 684316-181 module provides 16 GB of DDR3-1600 memory with ECC and registered signal processing. It operates at 1.50 V with a CL11 latency and uses the standard 240-pin form factor. The part is sold in refurbished condition.

Suits DDR3 servers needing ECC.

This memory fits servers that require registered ECC DDR3 DIMMs running at 1600 MHz. It will not work in systems that only accept unbuffered non-ECC modules or that use a different DDR generation. Buyers needing larger single-module capacities should look elsewhere.

16 GB capacity per module

Each DIMM delivers 16 GB, so the total memory added depends on how many modules the server can accept. Verify the platform's maximum supported capacity and slot count before purchasing.

Questions about this item

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

Yes, this module uses the standard 240-pin DDR3 DIMM form factor designed for compatible server memory slots.

What is the correct way to seat the registered ECC module so the system recognises the full 16GB?

Align the notch with the slot key, press down firmly until both side clips click shut, then verify 1600 MHz operation in BIOS.

When should I plan to replace the 1.50 V DDR3 sticks in a 24/7 server?

ECC registered DDR3 modules typically run for years; replace them only if memory diagnostics report correctable errors increasing over time.
