4GB DDR3 1333 Desktop Module

This single 4GB DDR3 DIMM runs at 1333 MHz with CL9 latency and 1.50 V standard voltage. It is an unbuffered, non-ECC module built with major-brand chips. The 240-pin form factor fits desktop systems that specify PC3-10600 memory.

DDR3 1333 Interface Limits

The DDR3 1333 standard tops out at 1333 MT/s, so this module cannot exceed that data rate even if the platform supports higher speeds. Bandwidth is capped at the PC3-10600 rating, and the 1.50 V supply is fixed for DDR3 operation. Motherboard chipsets that only recognise slower DDR3 grades will down-clock the module automatically.

Capacity and Headroom

A single 4 GB stick adds modest capacity for everyday desktop workloads such as web browsing, office applications and light multitasking. Systems with multiple DIMM slots can install additional identical modules to increase total memory, but a lone 4 GB module will reach its limit quickly with modern multitasking or memory-intensive applications.

Questions about this item

Should I choose the single 4GB module or look for a kit?

This item is a single 4GB stick; adding a second identical module later will let the board run in dual-channel mode if the motherboard supports it.

What does the 1333 MHz rating deliver in a real desktop?

The module runs at DDR3 1333 with CL9 latency at 1.5V, giving a peak transfer rate of PC3-10600 for everyday multitasking and office workloads.

How does the 240-pin DDR3 DIMM interface limit performance?

The 240-pin unbuffered DIMM slot caps speed to the DDR3 1333 standard, so the module operates at its rated 1333 MHz without overclocking headroom.
