The Intel H61 Express chipset is the single-chipset design to support the 1155 socket Intel Core i 7, Core i 5, Core i 3, Pentium, & Celeron processors. It provides enhanced performance by utilizing serial point-to-point links, which allows increased bandwidth & stability. The motherboard supports DDR3 memory that features data transfer rates of 1600/1333/1066 MHz to meet the higher bandwidth requirements of the 3D graphics, multimedia, & Internet applications. The dual-channel DDR3 architecture enlarges the bandwidth of your system memory to boost system performance. PCI Express 3.0 (PCIe 3.0) is the PCI Express bus standard with enhanced encoding schemes that provides twice the performance of the current PCIe 2.0. The total bandwidth for a x 16 link reaches a maximum of 32 Gb/s, double the 20 Gb/s of PCIe 2.0 (in x 16 mode). As such, PCIe 3.0 provides users an unprecedented data speeds, combined with the convenience & seamless transition offered by complete backward compatibility with PCIe 1.0 & PCIe 2.0 devices.
