Overview

The G.Skill 6GB (3 x 2GB) DDR3 1333 Triple Channel Kit is a purpose-built memory solution for desktop platforms that support triple-channel memory architectures, most notably Intel's X58 chipset on the LGA 1366 socket. By populating all three memory channels with matched 2GB modules, this kit maximizes the available memory bandwidth on these systems, providing a noticeable improvement in data throughput compared to single- or dual-channel configurations. Operating at DDR3-1333 (PC3-10666) speeds with CAS Latency 9 timings, it delivers dependable, stable performance for the workloads typical of systems from this era.

As a product from G.Skill, a brand well-regarded in the enthusiast memory market, this kit benefits from rigorous testing and broad compatibility with X58-based motherboards. The 240-pin DDR3 form factor is standard for desktop use, ensuring straightforward installation. While 6GB and DDR3-1333 speeds are modest by today's standards, this kit remains a practical option for users who need to maintain, repair, or modestly upgrade legacy triple-channel systems where newer memory technologies simply are not compatible.

Pros & Cons

👍 Pros

  • Triple-channel configuration provides increased memory bandwidth on compatible LGA 1366 platforms.
  • 6GB total capacity across three modules was a generous amount for the DDR3 era.
  • G.Skill's reputation for reliable, tested memory modules with strong compatibility.
  • DDR3-1333 speed with CL9 timings offers a well-balanced mix of performance and stability.
  • Pre-matched kit of three modules ensures compatibility and stable triple-channel operation.

👎 Cons

  • DDR3 technology is now several generations old, limiting this kit to legacy system upgrades or repairs.
  • 6GB total capacity is insufficient for modern workloads and operating systems.
  • Only compatible with the narrow range of motherboards that support triple-channel DDR3 (primarily LGA 1366).
  • 2GB per module is small by today's standards, offering no room for meaningful future expansion.
  • DDR3-1333 speed is at the lower end of the DDR3 spectrum, with faster DDR3-1600 and above options available.

Frequently Asked Questions

This triple-channel kit (3 x 2GB) is designed for platforms that support triple-channel memory, most notably Intel's LGA 1366 chipsets such as the X58.
Based on the model number (CL9), this kit operates at CAS Latency 9, which is standard for DDR3-1333 memory.
While the individual modules can physically work in a dual-channel board with DDR3 240-pin slots, you would lose the triple-channel advantage and would only use two of the three sticks for optimal dual-channel operation.
No. This is DDR3 memory with a 240-pin form factor. It is not physically or electrically compatible with DDR4 motherboards, which use 288-pin slots.
