8GB DDR3 1866 ECC RDIMM for Server Upgrades

This 8GB DDR3 1866 ECC RDIMM module targets administrators maintaining DDR3-era servers and workstations that require registered memory with error correction. It suits environments where system stability outweighs maximum throughput and existing slots accept 240-pin DIMMs. Buyers needing unbuffered UDIMMs or non-ECC memory for desktop platforms cannot use this module.

Direct Replacement for Hynix HMT41GR7 Series

The module replaces Hynix HMT41GR7AFR8C-RD, HMT41GR7BFR8C-RD, HMT41GR7DFR8C-RD, HMT41GV7AFR8C-RD and HMT41GV7BFR8C-RD parts with matching DDR3 1866 speed, CL13 latency, 1.50V voltage and 2Rx8 organisation. The upgrade is worthwhile when a failed stick must be swapped or when empty registered DIMM slots are available to increase total capacity. Systems already at the memory controller limit or restricted to lower speeds will not benefit.

240-Pin Registered DIMM for Multi-Module

The 240-pin registered DIMM fits server boards that buffer address and command signals, allowing larger memory arrays than unbuffered designs. It operates at standard DDR3 1.50V and requires a platform qualified for PC3-14900 registered ECC memory. The single 8GB stick leaves remaining slots free for identical modules to reach the platform's maximum supported capacity.

Questions about this item

Does the 240-pin DDR3 DIMM fit a standard registered server slot?

Yes, this module uses the 240-pin DDR3 DIMM form factor required by registered ECC server slots.

What BIOS setting must be enabled after seating the 2Rx8 registered module?

Enable ECC in the BIOS so the server recognises the registered 2Rx8 configuration and activates error correction.

When should the 1.50 V DDR3 1866 module be replaced?

Replace the module if memory diagnostics report correctable ECC errors that increase over time or if the system fails to POST with this DIMM installed.
