4GB DDR3 ECC Registered Module

This 4GB DDR3 1600MHz ECC RDIMM is a registered server memory module built to replace HP part 682416-001. It runs at PC3-12800 speed with CL11 latency and standard 1.5V operation. The single-rank 1Rx4 organisation uses major-brand chips on a 240-pin DIMM. It is intended for compatible HP server and workstation platforms that require registered ECC memory.

Suited for HP servers needing this exact part

System administrators maintaining HP hardware that specifies the 682416-001 part number will find a direct replacement here. The module delivers registered ECC reliability for mission-critical workloads. Buyers whose platforms require unbuffered UDIMMs, non-ECC memory, or different pin counts should look elsewhere. Compatibility must be verified against the system's qualified vendor list before purchase.

Registered ECC with 1Rx4 organisation

The registered buffer and ECC functionality are the defining specification that determines fit. Only systems designed for registered ECC RDIMMs can use this module; consumer desktop boards and platforms expecting unbuffered memory will not accept it. The 1Rx4 rank configuration and 1.5V voltage must match the motherboard's memory controller requirements.

Questions about this item

What does DDR3 1600 (PC3-12800) mean for actual server throughput?

The module runs at 1600 MHz with CL11 timing, giving the rated PC3-12800 data rate for registered ECC workloads

How does the registered ECC interface affect memory stability and capacity limits?

Registered signalling reduces electrical load on the memory controller, while ECC corrects single-bit errors for reliable 24/7 operation

Will this 240-pin DIMM fit my HP server's memory slots?

It uses the standard 240-pin DDR3 DIMM form factor built for HP part 682416-001, so it installs in matching registered DIMM slots
