32GB DDR3 ECC Kit for Workstations

This kit provides 32GB of DDR3 memory across four 8GB unbuffered ECC UDIMMs. It runs at 1333MHz with a CL9 latency and operates at 1.5V. The modules are designed for desktop workstations, servers and NAS systems that require error-correcting memory.

Check DDR3 ECC UDIMM Compatibility

Before ordering, confirm your motherboard supports DDR3 unbuffered ECC UDIMMs at 1333MHz and 1.5V. Verify the board has four available 240-pin DIMM slots and that the BIOS recognises ECC functionality. The kit is a dual-channel configuration intended for compatible workstation or server platforms.

Standard Voltage Thermals and Power

Operating at the standard 1.5V DDR3 voltage, these modules draw typical power for this memory class. Without heat spreaders, they rely on case airflow for cooling. In normal workstation or server workloads, thermals and acoustic output remain consistent with other unbuffered DDR3 DIMMs at this frequency.

Questions about this item

Will this 32 GB kit fit my workstation that requires DDR3 ECC unbuffered DIMMs?

The kit provides four 8 GB DDR3 1333 CL9 modules at 1.5 V, 240-pin unbuffered ECC — the standard specification for compatible workstations, servers and NAS systems.

Do I need to populate all four slots for the memory to work correctly?

Each module is a 2Rx8 8 GB DIMM; you can install fewer than four, but the rated dual-channel performance and full 32 GB capacity require all four slots populated.

Is the memory compliant with industry standards so it will not void my system warranty?

The modules are 100 % JEDEC-standard and RoHS compliant, designed and tested to meet or exceed OEM specifications for a warranty-safe upgrade.
