Qualified, Tested Memory for All Major Motherboards & Processors

As a pioneer in high-speed module design, Corsair has a long-standing working relationship with leading manufacturers of gaming machine systems to ensure our memory maximizes the potential of these performance systems. Our design teams work closely with major hardware manufacturers to release products that are 100% compatible with the latest DDR1 motherboards and processors.

TwinX Modules are Tested and Shipped as Matched Memory Pairs

When you need double the memory, choose Corsair XMS TwinX modules. These matched memory pairs are tested and shipped together for optimal performance in dual channel motherboards. The prefix TWIN in the part number identifies a matched memory pair.

Black or Platinum Heat Spreaders. The Choice is Yours

It's just a matter of style. The memory under the hood is the same, the heat spreader is the same. Just choose a part number with a PT for a platinum colored heat sink. Modules without a PT in the part number are our classic black.
