Server Memory Kit

This NEMIX RAM kit provides 256GB of DDR5 ECC registered memory across eight 32GB modules. It operates at 6400MHz with a CAS latency of 52 and a voltage of 1.1V. The 2Rx8 organisation suits multi-channel server platforms that require registered DIMMs. Buyers who need non-ECC or unbuffered memory for desktop PCs cannot use this product.

Platform Verification

Confirm that the motherboard supports DDR5 6400MHz registered ECC RDIMMs and accepts 288-pin modules in an eight-slot configuration. The system BIOS must be able to initialise 2Rx8 density at the rated speed and voltage. Servers limited to lower DDR5 speeds, unregistered DIMMs, or fewer than eight slots will not be compatible.

Build Integration

Each module draws 1.1V and fits a standard 288-pin DDR5 socket, leaving adjacent slots free for airflow in dense chassis. Registered buffering reduces electrical load on the memory controller, allowing all eight modules to run together without additional voltage tuning. The kit frees the builder from sourcing matched single sticks for high-capacity server deployments.

Questions about this item

What comes in the NEMIX RAM 256GB DDR5 6400MHz ECC RDIMM kit and do I need anything else to install it?

The kit contains eight 32GB DDR5 6400MHz PC5-51200 2Rx8 1.1V 288-pin ECC registered DIMMs. No extra parts are required for installation into a compatible server motherboard.

How do I decide between this 256GB 8×32GB kit and a smaller capacity kit?

Choose this 256GB kit when your server workload needs the full 256GB across eight slots; select a smaller kit if your board has fewer slots or the application does not require that much memory.

What does the 6400MHz speed mean for real-world server performance?

The modules run at DDR5 6400MHz (PC5-51200) with CAS latency 52 at 1.1V, delivering the rated throughput when the server platform supports DDR5 6400 operation.
