5/6 Series chipsets
Core i Series chipsets
The Nehalem microarchitecture, which is the basis of the Core i7 brand and projected additional brands, moves the memory controller onto the processor. For high-end Nehalem processors, the X58 IOH acts as a bridge from the QPI to PCI-Express peripherals and DMI to the ICH10 Southbridge. For mainstream and lower-end Nehalem processors, the integrated memory controller (IMC) is an entire Northbridge (some even having GPUs), and the PCH acts as a Southbridge. Not listed below is the 3450 chipset (see Xeon chipsets) which is compatible with Nehalem mainstream and high-end processors, and with either a Core i5 or i3 processor enables unbuffered ECC memory (this claim is in dispute - reference needed; see Talk:List_of_Intel_chipsets). Otherwise these chipsets don't enable unbuffered ECC memory.
