Server memory upgrade

This 64 GB DDR3 module is built for servers and workstations that need high-density registered memory. It uses a load-reduced DIMM design to support large capacities per slot. The part replaces Hynix HMTA8GL7AHR4C-PB and HMTA8GL7MHR4C-PB modules. It is intended for administrators expanding memory in compatible enterprise systems.

8Rx4 load-reduced organisation

The module implements an 8Rx4 rank structure with ECC error correction. This organisation determines whether the system memory controller can address the full 64 GB capacity. Verify that your platform supports LRDIMM 8Rx4 modules before purchase. Incompatible controllers will not recognise the memory.

Standard DDR3 voltage and thermals

The module operates at the standard 1.5 V DDR3 voltage. Load-reduced buffering reduces electrical load on the memory bus, which helps limit heat output in densely populated slots. Typical airflow in a server chassis is sufficient for normal operation. No additional cooling measures are required.

Questions about this item

How does 64 GB in a single LRDIMM behave once installed in a server?

The 64 GB capacity appears as one large addressable bank, letting the operating system allocate memory for virtual machines or large data sets without spreading the load across multiple slots.

What does the DDR3 1600 PC3-12800 interface limit in practice?

The DDR3 1600 interface caps the peak transfer rate at the PC3-12800 specification, so sustained throughput cannot exceed that ceiling even if the memory controller runs faster.

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

The module uses a 240-pin DIMM form factor and requires a standard DDR3 server slot with enough vertical clearance for the tall LRDIMM heatsink.
