4GB DDR3 1333MHz ECC UDIMM

This 4GB DDR3 module runs at 1333MHz with CL9 latency and operates at the standard 1.50V. It is an unbuffered ECC UDIMM built with a 2Rx8 rank configuration using major brand chips. The 240-pin DIMM is designed for server and workstation systems that require error-correcting memory.

Sustained load stability

Error-correcting code detects and corrects single-bit errors during continuous operation, preventing data corruption in long-running workloads. The unbuffered design connects directly to the memory controller without a register, which keeps latency low for typical server tasks. Major brand chips and quality assurance testing support consistent reliability over extended periods.

DDR3 platform limits

The DDR3 1333MHz PC3-10600 standard caps bandwidth at this speed grade, so faster modules will downclock to match the system's maximum supported frequency. Compatibility depends on the motherboard accepting unbuffered ECC UDIMMs at 1.50V; registered or load-reduced DIMMs will not work in the same slots. Verify your system documentation for supported capacities and population rules before installing.

Questions sur cet article

How much heat and power does the 1.50 V DDR3 1333 module draw when the server runs continuously?

At the standard 1.50 V DDR3 voltage the 4 GB stick draws only modest power and generates little heat, so it stays cool inside a 24/7 server chassis without extra airflow.

What motherboard slot and memory type must my system already have for this 240-pin DDR3 UDIMM to work?

Your board needs a DDR3 240-pin UDIMM slot that accepts unbuffered ECC memory; registered or buffered slots will not accept this module.

Can I add this CL9 2Rx8 stick alongside older DDR3 1333 modules that have different latency or rank?

Yes — the motherboard will run all installed DDR3 1333 modules at the slowest common speed and latency, so mixing CL9 2Rx8 with other DDR3 1333 sticks works, though timings will match the loosest module.
