Product Description The XMS range of DDR3 desktop high-speed memory modules boasts both reliable and affordable performance. When you are thinking about upgrading your PC memory, XMS is a simple and affordable solution. Short description Corsair XMS: The performance basics The XMS aluminum heatsinks dissipate excess heat and keep it away from the circuits. XMS Heatsink Higher storage speed is accompanied by stronger heat generation, which can lead to reduced reliability and lower life of individual components. The XMS aluminum heatsinks dissipate excess heat and keep it away from the circuits. DDR3 DIMM memory modules have a cut-out on the connection side measured 5.5 cm from the left side. These modules are not compatible with DDR2 and/or DDR1 motherboards. Proven reliability For us, reliability and speed play a crucial role. XMS memory is subject to stringent two-step quality control where the circuits undergo in-depth testing before assembly and completed modules prior to launch. Guaranteed compatibility XMS memory is guaranteed to be compatible with desktop PCs equipped with standard DDR3 DIMM memory. With module clock speeds of at least 1600 MHz, Intel XMP can easily improve the performance of the DRAM. A 64-bit operating system is necessary to address more than 4GB. This is independent of the memory provider. With a 32-bit operating system, a maximum of 3.2 GB can be detected. The Corsair Advantage Throughout our long history we have earned an outstanding reputation as an innovative manufacturer of overclocked memory and peripherals for the highest demands with high-quality, compatible and high-performance products.
