List of Intel chipsets

An earlier chipset support for Intel 8085 microprocessor can be found at MCS-85 family section.

The 82231 covers this combination of chips: 8254 interrupt timer, 74LS612 memory mapper and dual 8237A DMA controller among with other components.

[2] This chipset can be used with an 82335 High-integration Interface Device to provide support for the Intel 386SX.

L2 caches are direct-mapped with SRAM tag RAM, write-back for 430FX, HX, VX, and TX.

[1] Some later revisions of motherboards based on 945P,945G and 945PL chipset usually supports some Core 2 processors (with later BIOSes).

Support for all NetBurst based processors was officially dropped starting with the Bearlake chipset family.

Otherwise it and the lower slot (both attached to the Memory Controller Hub) operate at ×8 electrically.

Unofficially, third-party motherboards (Asus, Gigabyte) support certain 1333FSB 45 nm Core2 processors, usually with later BIOS updates.

X38/X48 VT-d support is limited to certain Intel, Supermicro, DFI (LanParty) and Tyan boards.

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.

The PCIe 2.0 lanes from the PCH ran at 5 GT/s in this series, unlike in the previous LGA 1156 chips.

[78] 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.

The Z68 chipset which supports CPU overclocking and use of the integrated graphics does not have this hardware bug, however all other ones with B2 did.

[83] 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.

[88] The 100 Series chipsets (codenamed Sunrise Point), for Skylake processors using the LGA 1151 socket,[90] were released in the third quarter of 2015.

[91] The 200 Series chipsets (codenamed Union Point) were introduced along with Kaby Lake processors, which also use the LGA 1151 socket;[92] these were released in the first quarter of 2017.
