4GB DDR3 1333 module

This 4GB DDR3 1333 desktop memory module runs at PC3 10600 speed with CL9 latency and 1.50V operation. It is an unbuffered, non-ECC stick built for standard desktop motherboards. The single-module design suits upgrades or new builds that need a basic capacity increase.

Unbuffered non-ECC design

The unbuffered layout removes the register stage found in server memory, lowering latency for typical desktop workloads. Non-ECC operation means no error-correction overhead, which matches most consumer platforms that do not support ECC. These traits keep the module compatible with ordinary desktop chipsets.

DDR3 1333 interface

The DDR3 1333 interface fits motherboards with DDR3 slots keyed for 240-pin DIMMs. Standard 1.50V voltage aligns with default JEDEC specifications, so the module works without manual voltage changes. Physical dimensions follow the DDR3 DIMM standard for straightforward installation.

Questions about this item

Will the 4GB DDR3 1333 module need replacement due to wear over time?

DDR3 DRAM has no moving parts and no write-cycle limit, so the module itself does not wear out; replacement is only needed if a fault develops or capacity requirements change.

What limit appears first when the CL9 1.50V stick runs sustained workloads?

The JEDEC-rated 1333 MT/s speed and CL9 latency are the fixed performance ceiling; the module cannot exceed these specifications under continuous use.

How much heat and power does the unbuffered 4GB DDR3 1333 draw during all-day operation?

At the standard 1.50V the module draws roughly 2–3 watts and runs cool enough for passive airflow in a typical desktop case.
