Take advantage of the most significant architectural change in the x86 architecture in 13 years, the Intel Core i7. The MSI Eclipse SLI introduces a new era for extreme performance. It is an X58-based motherboard that supports Intel’s new generation extreme performance Core i7 Processors and both SLI and CrossFireX! Six SATA ports with RAID 0, 1, 5, and 10 as well as two SAS, or Serial Attached SCSI, ports supporting RAID 0 and 1 give you plenty of storage options and the ability to use hard drives with speeds of up to 15,000 RPMs. Memory support includes up to 24GB of Triple Channel DDR3 memory. Intel has brought back Hyperthreading technology and combined it with a native quad-core design to give support for 8 seperate threads in the new LGA1366 / Socket B CPU interface and their replacement for the old Front Side Bus technology, QuickPath Interconnect provides a system bus speed of up to 6.4GT/s.
