4GB DDR3 1333 ECC UDIMM

This 4GB DDR3 1333 module adds ECC protection to workstations, servers and NAS systems that require data integrity. It runs at PC3-10600 speed with CL9 latency and a standard 1.5V supply. The unbuffered design fits desktop DIMM slots without registered buffering.

240-pin installation fits standard slots

The 240-pin UDIMM seats in any desktop DDR3 slot that accepts unbuffered ECC memory. No heat spreader means low profile clearance for tight CPU coolers. Systems that require registered DIMMs will not post with this module, so verify the platform before fitting.

Sustained load stability with ECC

Error-correcting code detects and corrects single-bit errors during long compute runs, preventing silent data corruption in file servers or rendering farms. JEDEC-compliant 1.5V operation keeps thermals steady without extra cooling. The module maintains rated 1333MHz throughput continuously rather than throttling.

Questions about this item

How can I verify the module is running at DDR3 1333 CL9 after installation?

Check the memory speed and timings in the BIOS or a system-information tool; they should show 1333 MHz and CL9 for this DDR3 ECC UDIMM.

What comes in the package and do I need anything else to install it?

The box contains one 4 GB DDR3 1333 ECC unbuffered 240-pin UDIMM; no extra parts or cables are required for installation.

Which capacity version should I choose for a workstation that supports ECC unbuffered memory?

This module is a single 4 GB stick; add multiple identical modules to reach the total capacity your workstation’s memory slots allow.
