The nForce 700 is a chipset series designed by Nvidia first released in December 2007. The series supports both Intel Core 2 and AMD Phenom processors, and replaces the nForce 600 series chipsets. Several members were spotted, including the codenamed MCP72 for AMD processors and the C72 for Intel processors, launched with the name "nForce 780a" and "nForce 780i" chipsets respectively. Currently, the released variants are the 750i, 780i, 790i, and 790i Ultra.
AMD chipsets The memory controller is built-in into the CPU, the supported memory type depends on the CPU and socket used. This way there are no supported memory types listed here.
