4GB DDR3 1333MHz Desktop DIMM

This A-Tech module provides 4GB of DDR3 memory at 1333MHz (PC3-10600) with CL9 latency. It uses the standard 240-pin DIMM form factor and operates at 1.5V. The unbuffered, non-ECC design suits typical desktop systems from AMD and Intel platforms. It is built as a direct replacement for several Dell part numbers.

Check motherboard DDR3 support and slot availability

Verify that your motherboard accepts DDR3 DIMMs and has a free 240-pin slot before ordering. The module runs at 1.5V, so the board must supply that voltage. Confirm the maximum supported capacity per slot and total system limit in your manual. Cross-reference the listed Dell part numbers such as A5039651 or SNP1333D3U9/4G if you are replacing a specific OEM module.

Major-brand chips on standard green PCB

The stick uses major-brand memory chips mounted on a conventional unbuffered DIMM PCB. Gold edge contacts fit any standard 240-pin DDR3 socket without adapters. The single-rank 2Rx8 organisation keeps electrical loading low for broad compatibility. No heatsink or tall profile is present, so the module clears most CPU coolers and fits in compact cases.

Questions about this item

Does the module ship alone or with any extra parts?

The package contains one 4GB DDR3 1333MHz 240-pin DIMM; no cables, brackets or tools are included.

Should I pick this 4GB stick or look for a larger capacity?

This single 4GB module suits a basic upgrade; add a second identical stick if your board supports dual-channel and you need 8GB total.

What does the 1333MHz rating mean for everyday use?

It sets the maximum data rate at 1333 MT/s with CL9 latency at 1.5V, matching standard DDR3 desktop specs for stable operation.
