NEMIX RAM 16GB DDR4 ECC Kit

This NEMIX RAM CSE-735D4-668B kit provides 16GB of DDR4 3200 ECC unbuffered memory in a matched pair of 8GB modules. It is built for the Supermicro SuperWorkstation SYS-530A-IL and X12SAE-5 motherboard.

Suited for ECC workstation upgrades

The kit suits administrators expanding memory in compatible Supermicro workstations that require ECC UDIMM modules. It is not for systems that need registered DIMMs, higher capacities per slot, or non-ECC consumer memory.

Straightforward UDIMM installation

Installation follows standard 288-pin DDR4 UDIMM procedure and typically takes minutes. Common issues include failing to seat both modules fully or mixing with existing memory of different rank or speed, which can prevent the system from posting.

Questions about this item

Does this 16 GB kit require a motherboard with 288-pin DDR4 slots?

Yes, the two 8 GB modules use the 288-pin DDR4 UDIMM form factor and will only fit DDR4-compatible slots.

Will the CL22 timing work if I keep my existing 3200 MHz memory?

The kit runs at DDR4 3200 with CL22; mixing with other DDR4 3200 modules is possible but the system will operate at the slowest common timing.

How can I confirm the ECC function is active after installing the kit?

Enter the BIOS or use an OS tool such as dmidecode to verify that ECC is reported as enabled for the new 16 GB capacity.
