Server Memory Upgrade

This 4 GB DDR3 registered DIMM is built for servers and workstations that require ECC protection. It replaces Hynix HMT451R7AFR8C-PB and equivalent modules in compatible systems.

ECC Registered DDR3 1600

The module runs at DDR3 1600 (PC3-12800) with CL11 latency and 1.50 V standard voltage. Its 1Rx8 registered organisation is the key specification that determines whether the board will accept it.

Thermals and Power

Standard 1.5 V DDR3 voltage keeps power draw low during typical server workloads. The registered buffer adds minimal overhead while maintaining signal integrity at 1600 MHz.

Questions about this item

What does the 1600 speed rating mean once this module is installed in a server?

The module runs at 1600 MT/s, giving a PC3-12800 data rate that the memory controller uses for read and write cycles.

How does the DDR3 interface and registered design affect what the system can use?

The 240-pin DDR3 interface fits DDR3 RDIMM slots, and the registered buffer lets the memory controller drive larger capacities per channel.

What physical slot and clearance does this 240-pin DIMM need to fit?

It requires a standard DDR3 240-pin DIMM socket; the registered height matches regular RDIMM profiles for server and workstation boards.
