Compatible 8GB DDR3 server module

This 8GB DDR3 1333MHz ECC registered DIMM replaces Hynix HMT31GR7AFR4C-H9 and equivalent part numbers in server and workstation systems. It uses major-brand chips and operates at the standard 1.5V voltage with CL9 latency. The module is tested for dependable operation in enterprise environments.

Upgrading from smaller DDR3 ECC DIMMs

When your current DDR3 registered memory limits multitasking or virtualisation capacity, adding this 8GB module extends headroom for higher workloads. The jump is worth it if the platform supports DDR3 1333 registered ECC and has free 240-pin DIMM slots. It does not suit systems requiring unbuffered or non-ECC memory.

Verify platform and slot requirements

Confirm the motherboard accepts DDR3 1333 registered ECC RDIMMs in a 240-pin form factor before ordering. Check the maximum supported capacity per slot and total system limit in the system documentation. Ensure the memory controller allows 2Rx4 organisation and 1.5V operation for stable compatibility.

Questions about this item

Does the 240-pin DDR3 DIMM fit standard server memory slots?

Yes, the module uses the standard 240-pin DDR3 DIMM form factor used by most DDR3 server and workstation boards.

What is the correct orientation when seating this registered ECC module?

Align the notch on the gold edge connector with the key in the slot, press down evenly until both retention clips click, and confirm the module sits flush.

Will the 1.5 V DDR3 chips need active cooling or replacement over time?

The chips run at standard 1.5 V with no moving parts; they require no active cooling and typically last the life of the server unless a fault occurs.
