A-Tech 4GB DDR3 1333 Desktop Module

This 4GB DDR3 DIMM runs at 1333MHz with CL9 latency and 1.50V operation. It is an unbuffered, non-ECC module built as a direct replacement for several G.Skill kits. The single stick suits desktop owners who need a straightforward capacity increase without changing voltage settings.

DDR3 1333 PC3-10600 Interface Limits

The DDR3 1333 standard caps data rates at 1333 MT/s and uses 240-pin DIMM connectors keyed for 1.5V signalling. Systems that only support lower DDR3 speeds will down-clock the module automatically. Boards requiring registered or ECC memory cannot use this unbuffered stick.

Replaces G.Skill F3-10666CL9 Series Kits

This module replaces G.Skill part numbers F3-10666CL9D-8GBXL, F3-10666CL9Q-16GBRL, F3-10666CL9S-4GBRL, F3-10666CL9T-12GBRL and F3-10666CL9T2-24GBRL. The upgrade is worth it when an exact-capacity match is needed to complete a dual-channel pair or to restore a failed stick in those kits.

Questions about this item

Is this 4 GB module the only capacity available or are larger kits offered?

The listing covers a single 4 GB stick; the compatible G.Skill part numbers reference 8 GB, 12 GB, 16 GB and 24 GB kits built from multiple modules.

What does the 1333 MHz rating mean for actual system performance?

The module runs at 1333 MHz with CL9 timing at 1.5 V, delivering standard DDR3 desktop bandwidth for everyday workloads.

Does the 240-pin DIMM fit every DDR3 motherboard?

It uses the standard 240-pin DDR3 DIMM form factor, so it installs in any desktop board with a DDR3 slot that accepts unbuffered non-ECC memory.
