This article covers CORSAIR Memory Module DDR3 デスクトップ DOMINATOR Series 4GB×2kit CMP8GX3M2A1600C9.

Overview

The CORSAIR DOMINATOR series has long been synonymous with high-end memory performance. The CMP8GX3M2A1600C9 is an 8GB dual-channel kit consisting of two 4GB DDR3-1600MHz (PC3-12800) modules, with CAS latency 9 and timings of 9-9-9-24. It supports Intel XMP (Extreme Memory Profile), allowing users to achieve rated speeds with a single click on compatible motherboards. This memory is designed for DDR3-based desktop platforms, including Intel LGA1155/1150/1366 and AMD AM3+/FM1/FM2 systems. The large black DOMINATOR heatsink provides effective cooling, and the optional DHX (Dual-Path Heat eXchange) connector allows for an additional cooling fan to be attached for extreme overclocking. In its era, this kit occupied the high-end tier of DDR3 memory, favored by overclockers and enthusiasts. Today, with DDR4 and DDR5 dominating the market, it serves primarily as a reliable upgrade for legacy systems or budget builds using older hardware.

Compatibility Guide

Memory type: DDR3 only. Not compatible with DDR4 or DDR5 slots. Form factor: 240-pin Unbuffered DIMM, designed for desktop motherboards. Not for laptops (SO-DIMM). Voltage: 1.5V standard. XMP may auto-configure voltage on supported boards. Compatible chipsets: Intel 6-series, 7-series, 8-series, X58; AMD 7xx, 8xx, 9xx series, and FM1/FM2. Dual-channel operation requires matched pairs; this kit is pre-matched for dual-channel. Heatsink height is slightly taller than standard DIMMs. Check clearance with large CPU coolers, especially top-flow or side-flow designs.

Product Info

The CORSAIR DOMINATOR DDR3 8GB kit (CMP8GX3M2A1600C9) was originally released around 2010 with a retail price near ¥10,000. Today, it can be found on the used market or clearance sales for around ¥3,000–¥5,000. It comes with a lifetime warranty from CORSAIR, though this applies to original purchases from authorized retailers. Market positioning: high-end DDR3 memory for enthusiasts. Key features include XMP support, premium heatsink, and upgrade connector for active cooling. However, it is now a legacy product and not suitable for modern platforms.

Best Use Cases

Legacy system upgrades: If you own an older PC with a Core i7-2600K or FX-8350, this memory can breathe new life into it. XMP makes it easy to get full performance without manual tweaking. Budget secondary PC builds: When assembling a low-cost secondary machine from used parts, this kit offers reliable performance and the peace of mind of a lifetime warranty (if original). * Overclocking experimentation: The robust heatsink and optional fan attachment make this kit suitable for pushing DDR3 beyond 1600MHz, ideal for hobbyists who enjoy tuning older hardware. ## Alternatives
A direct competitor is the G.Skill RipjawsX DDR3-1600 8GB kit (F3-12800CL9D-8GBXL), which offers identical timings and similar pricing. The G.Skill kit is often easier to find and slightly cheaper, but lacks the upgrade connector for active cooling. The CORSAIR DOMINATOR has a more premium aesthetic and better thermal expansion options. Another alternative is the Crucial Ballistix DDR3-1600 8GB kit. Crucial modules are known for broad compatibility and reliability, but they typically don't overclock as well as the DOMINATOR series. For pure stability and budget, Crucial is a solid choice; for overclocking headroom and brand prestige, CORSAIR wins.

Things to Consider

Not for modern systems: This memory is strictly for DDR3 platforms. Do not attempt to install it in a DDR4 or DDR5 motherboard. Capacity limitations: 8GB total is the bare minimum for today's operating systems and applications. For gaming or content creation, consider a 16GB kit if your motherboard supports it. Availability and warranty: New stock is scarce; most units are used. The lifetime warranty may not transfer to second-hand buyers. Verify the seller's return policy before purchasing. Physical clearance: The tall heatsinks can interfere with large CPU coolers or compact cases. Measure your available space, especially in Mini-ITX builds.
