4 GB DDR3 1333 Upgrade Module

This 4 GB DDR3 1333 module is a direct replacement for several Kingston desktop DIMMs and works with AMD and Intel platforms that accept unbuffered non-ECC memory. The single stick adds capacity without requiring paired installation.

DDR3 1333 interface limits

The DDR3 1333 standard tops out at 1333 MT/s with a 1.5 V supply, so the module cannot run faster than that ceiling on any motherboard. Systems locked to lower DDR3 speeds will down-clock the stick automatically.

CL9 latency at 1.5 V

CAS latency 9 at the standard 1.5 V is the key timing figure; if your board or existing memory requires a different latency or voltage this module will not be the correct match.

Questions about this item

Should I pick a single 4 GB stick or a matched pair for dual-channel?

This listing is a single 4 GB DDR3 1333 module; add a second identical stick to run dual-channel on a supporting motherboard.

What real-world speed does the 1333 MHz rating deliver inside my desktop?

The module runs at 1333 MT/s with CL9 latency at 1.5 V, giving standard DDR3-1333 bandwidth for everyday desktop workloads.

Does the 240-pin DDR3 DIMM fit any desktop board with DDR3 slots?

It uses the standard 240-pin unbuffered DDR3 DIMM form factor, so it fits any desktop DDR3 slot that accepts 1.5 V non-ECC modules.
