This motherboard supports the Intel Ivy Bridge processors in the LGA1155 package, with memory & PCI Express controllers integrated to support 2-channel DDR3 memory & 16 PCI Express 2.0 lanes. This provides great graphics performance. Intel Ivy Bridge processors are among the most powerful & energy efficient CPUs in the world. The PCI Express bus standard delivers enhanced encoding for twice the performance of current PCIe 2.0. Total bandwidth for a x 16 link reaches a maximum of 32GB/s, double the 16GB/s of PCIe 2.0 (in x 16 mode). PCIe 3.0 provides users unprecedented data speeds, combined with the convenience & seamless transition offered by complete backward compatibility with PCIe 1.0 & PCIe 2.0 devices.
