128GB DDR5 4800 ECC RDIMM kit

This 128GB kit contains two 64GB DDR5 4800 registered DIMMs with ECC and a CAS latency of CL40. It is built for THINKMATE SuperServer 511E-WR and 521E-WR systems that require registered server memory. Modules operate at 1.1V and use a 2Rx4 organisation.

Compatibility check before ordering

Verify that your motherboard accepts 288-pin DDR5 RDIMMs and supports registered ECC modules at 4800 MT/s. Confirm the platform can address 64GB per slot and that the BIOS is current enough for this density. Ensure the server chassis has enough DIMM slots free for both modules.

Build integration and capacity gains

The kit plugs directly into standard 288-pin DDR5 RDIMM slots and draws 1.1V from the platform. No heat spreaders are fitted, so airflow across the modules must be maintained by the server's cooling design. Installing the pair adds 128GB of registered ECC capacity, freeing the system from lower-density configurations.

Questions about this item

Does the kit include both 64 GB modules or must the second stick be ordered separately?

The kit contains two 64 GB modules for a total of 128 GB, so nothing else needs to be purchased.

Should I choose the 2Rx4 organisation or a different rank for the ThinkMate SuperServer 511E-WR and 521E-WR?

The 2Rx4 organisation is the one qualified for these SuperServer models and matches the memory controller layout.

What does the 4800 MT/s rating mean once the modules are installed in the server?

The memory will run at 4800 MT/s with CL40 latency at 1.10 V, delivering the rated PC5-38400 bandwidth.
