List of Intel chipsets

Intel ICH7 southbridge on an Intel D945GCPE desktop motherboard

This article provides a list of motherboard chipsets made by Intel, divided into three main categories: those that use the PCI bus for interconnection (the 4xx series), those that connect using specialized "hub links" (the 8xx series), and those that connect using PCI Express (the 9xx series). The chipsets are listed in chronological order.

Pre-chipset situation

Early IBM XT-compatible mainboards did not have a chipset yet, but relied instead on a collection of discrete TTL chips by Intel:[1]

Early chipsets

To integrate the functions needed on a mainboard into a smaller amount of ICs, Intel licensed the ZyMOS POACH chipset for its Intel 80286 and Intel 80386SX processors (the 82230/82231 High Integration AT-Compatible Chip Set). This chipset can be used with an 82335 High-integration Interface Device to provide support for the Intel 386SX.[2]

List of early Intel chipset includes:[3][4]

Pentium chipsets

While not an actual Intel chipset bug, the Mercury and Neptune chipsets could be found paired with RZ1000 and CMD640 IDE controllers with data corruption bugs. L2 caches are direct-mapped with SRAM tag RAM, write-back for 430FX, HX, VX, and TX.

All Core 2 Duo chipsets support the Pentium Dual-Core and Celeron processors based on the Core architecture. Support for all NetBurst based processors was officially dropped starting with the P35 chipset family.[33] However, some motherboards still support the older processors.[34]

[*] Remapping of PCIE/APIC memory ranges not supported,[31] some physical memory might not be accessible (e.g. limited to 3.5 GB or similar). Operational configuration is 4 ranks - 2× 2 GB dual rank modules or 4× 1 GB single rank modules - depends on number of motherboard DDR2 slots.

Summary:

[1] The 975X chipset supports only ×16 PCI Express (electrically) in the top slot when the slot below it is unpopulated. Otherwise it and the lower slot (both attached to the Memory Controller Hub) operate at ×8 electrically.

[2] Officially 975X supports a maximum of 1066 MT/s FSB. Unofficially, third-party motherboards (Asus, Gigabyte) support certain 1333FSB 45 nm Core2 processors, usually with later BIOS updates.

[3] The 975X chipset technical specification shows only DDR2-533/667 memory support. Actual implementations of 975X do support DDR2 800.

[4] VT-d is inherently supported on these chipsets, but may not be enabled by individual OEMs. Always read the motherboard manual and check for BIOS updates. X38/X48 VT-d support is limited to certain Intel, Supermicro, DFI (LanParty) and Tyan boards. VT-d is broken or non existent on some boards until the BIOS is updated. Note that VT-d is a chipset Memory Controller Hub technology, not a processor feature, but this is complicated by later processor generations (Core i3/i5/i7) moving the MCH from the motherboard to the processor package, making only certain I series CPUs support VT-d.

5/6/7/8/9 Series chipsets

The Nehalem microarchitecture moves the memory controller into 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 (Platform Controller Hub) acts as a southbridge.

Not listed below is the 3450 chipset (see Xeon chipsets) which is compatible with Nehalem mainstream and high-end processors but does not claim core iX-compatibility. With either a Core i5 or i3 processor, the 3400-series chipsets enable the ECC functionality of unbuffered ECC memory.[46] Otherwise these chipsets do not enable unbuffered ECC functionality.

The Cougar Point Intel 6 series chipsets with stepping B2 were recalled due to a hardware bug that causes their 3 Gbit/s Serial ATA to degrade over time until they become unusable. Stepping B3 of the Intel 6 series chipsets will have the fix for this. The Z68 chipset which supports CPU overclocking and use of the integrated graphics does not have this hardware bug.[47] The Z68 also added support for transparently caching hard disk data on to solid-state drives (up to 64 GB), a technology called Smart Response Technology.[48]

LGA 1150

Chipsets that support LGA 1150 CPUs are listed below. Haswell and Haswell Refresh CPUs are supported by all listed chipsets; however, a BIOS update is usually required for 8-Series Lynx Point motherboards to support Haswell Refresh CPUs.[51] Broadwell CPUs are supported only by 9-Series chipsets, which are usually referred to as Wildcat Point.[52]

The C1 stepping of the Lynx Point chipset contains a bug  a system could lose connectivity with USB devices plugged into USB 3.0 ports provided by the chipset if the system enters the S3 sleep mode.[53]

Notes

  1. The Pentium Pro, Pentium II/III, and the Celerons based on them are essentially the same design with minor internal revisions and varying cache designs. Because of this, the same chipset can be used for Socket 8, Socket 370, Slot 1, or Slot 2 designs with any CPU in the P6 family. In practice however, newer chipset designs are usually made only for the newer processor packages, and older ones may not be updated to accommodate for recent package designs. In addition, certain chipsets may be implemented in motherboards with different processor packages, much like how the 440FX could be used either with a Pentium Pro (Socket 8) or Pentium II (Slot 1). A new feature for the latest Intel chipsets is hardware virtualization support (Intel VT-d).[24] The chipset support for this technology is not very clear for the moment.[25]
  2. The Intel 82943GML mobile chipset unofficially supports Core Duo, Core 2 Duo, and Pentium Dual Core processors as well as 667 MHz FSB, which is a popular upgrade for many older notebook computers such as certain models of Acer Aspire 3680.
