DDR3 1333 ECC UDIMM Kit

This 8 GB kit contains two 4 GB unbuffered DDR3 modules rated at 1333 MHz with CL9 latency. ECC support detects and corrects single-bit errors, making the set suitable for workstations, servers and NAS appliances that require data integrity. The modules operate at the standard 1.5 V JEDEC voltage.

Dual-channel 240-pin desktop memory

The pair installs in matching DIMM slots to enable dual-channel operation on any desktop, workstation or server board that accepts 240-pin DDR3 UDIMMs. No heat spreaders are fitted, so the modules sit low in crowded chassis and leave clearance for large CPU coolers. JEDEC compliance ensures a warranty-safe upgrade without BIOS tuning.

Sustained load stability with ECC

Under continuous workloads the ECC logic corrects single-bit errors on the fly, preventing silent data corruption during long render, compile or file-serving sessions. Standard 1.5 V operation keeps power draw predictable, while the absence of heat spreaders allows direct airflow from case fans to the DRAM. Dual-channel bandwidth remains consistent across extended use.

Questions about this item

Will this kit work in a standard desktop motherboard that supports DDR3 1333?

Yes, the modules are 240-pin DDR3 1333 UDIMMs. They fit any desktop board with DDR3 slots that accept unbuffered ECC memory.

Do I need a CPU or chipset that specifically supports ECC for these modules to function?

ECC operation requires a processor and chipset that implement ECC. On platforms without ECC support the memory will still run, but the error-correction feature will be inactive.

What voltage do these DIMMs require and is it compatible with typical DDR3 systems?

The kit runs at 1.5 V, which is the standard JEDEC voltage for DDR3 and matches the vast majority of desktop and workstation platforms.
