Server ECC RDIMM replacement module

This 8 GB DDR3 registered DIMM replaces Hynix HMT41GV7BMR8C-G7 and HMT41GV7AMR8C-G7 parts in compatible servers and workstations. It delivers error-correcting code protection and registered signalling for stable operation under sustained loads. The module runs at 1066 MHz with CL3 latency at the standard 1.50 V DDR3 voltage.

Upgrade from non-ECC or lower-capacity DDR3

Swapping unbuffered or non-ECC memory for this registered ECC module adds data-integrity safeguards required by many server platforms. The jump is worthwhile when the system board specifies registered DIMMs and the workload demands the reliability that ECC provides. Systems limited to unbuffered memory cannot use this module.

8 GB capacity for virtualization

The single 8 GB rank handles moderate virtual-machine densities, database buffer pools and multi-threaded application caches. Workloads that exceed the installed memory ceiling will trigger paging and reduce throughput. Buyers needing larger per-slot densities or higher memory bandwidth should verify platform support for larger registered modules.

Questions about this item

Will this 240-pin DDR3 DIMM fit in my server's memory slots?

Yes, the module uses the standard 240-pin DDR3 DIMM form factor required for registered DDR3 server slots.

What is the correct way to seat this registered ECC module, and what step is often missed?

Align the notch with the slot key, press firmly until both side clips click shut, then verify the system recognises the full 8 GB and ECC function in BIOS.

When should this 8 GB DDR3 1066 MHz module be replaced?

Replace it if memory diagnostics report uncorrectable ECC errors or the system fails to POST with the module installed.
