8GB DDR3 1333 ECC Unbuffered module

This 8 GB DDR3 1333 ECC unbuffered DIMM is built for servers and workstations that require error-correcting memory without registered buffering. It suits system builders and integrators assembling white-box platforms where JEDEC-standard reliability matters.

Upgrade from non-ECC or lower-capacity DDR3

The module replaces standard non-ECC DDR3 sticks when data integrity is a priority, and it adds capacity over 4 GB or 2 GB DDR3 1333 modules. The jump is worth it when the platform supports unbuffered ECC and the workload benefits from corrected single-bit errors.

8 GB capacity for mainstream server workloads

Eight gigabytes handles typical file, print and light virtualization tasks on a single DIMM per channel. Headroom runs out with heavy database buffers, large VM fleets or memory-intensive compute jobs that demand multiple modules per channel or higher-density registered DIMMs.

Questions about this item

Will the 240-pin DDR3 module fit my server's DIMM slots?

This module uses the standard 240-pin DDR3 form factor and runs at 1.50V, matching JEDEC specifications for DDR3 1333 server memory slots.

What is the correct way to seat this ECC unbuffered DIMM?

Align the notch on the module's gold edge connector with the key in the slot, then press down firmly on both ends until the retention clips click into place automatically.

Does this ECC memory require any periodic maintenance or component replacement?

No, the solid-state DRAM chips and PCB have no moving parts or consumable components, so no scheduled maintenance or replacement is needed during its service life.
