8GB DDR3 1066MHz ECC RDIMM for Servers

This 8GB DDR3 module runs at 1066MHz with PC3-8500 rating and CL7 latency. It is built as a registered DIMM with ECC for error correction in server and workstation platforms. The 4Rx8 organisation suits high-density memory configurations. Voltage is 1.50V, matching the DDR3 standard.

Registered ECC with 4Rx8 organisation

The single specification that decides fit is the registered ECC RDIMM design combined with a 4Rx8 rank structure. Only systems that explicitly support registered ECC memory and accept 4Rx8 modules can use this part. Standard desktop boards or platforms requiring unbuffered non-ECC DIMMs will not work with this module.

Direct replacement for Hynix part numbers

The module is validated as a compatible equivalent for Hynix HMT31GR7AFR8C-G7 and HMT31GR7BFR8C-G7. This matching lets buyers replace failed or expand existing kits without guessing pinout or timing. No extra accessories or software are bundled with the memory stick.

Questions about this item

What does DDR3 1066MHz (PC3-8500) mean for my server's actual performance?

The module operates at 1066MHz with CL7 latency, providing the data rate your system's memory controller is designed for in DDR3 server platforms.

How does the registered ECC design affect compatibility and data integrity?

As a 4Rx8 registered ECC DIMM, it places less electrical load on the memory bus and corrects single-bit errors, but requires a motherboard that supports registered DDR3 memory.

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

It fits a standard DDR3 240-pin DIMM socket; verify your server's DIMM spacing and heatsink clearance before installing.
