Sandy Bridge CPUs will provide up to 40 PCIe 3.0 lanes for direct GPU connectivity and additional 4 PCIe 2.0 lanes. NOTE: This reference number 4 is on X79, which is a Sandy bridge -E, not Sandy Bridge, and PCIe 3.0 only is enabled when an Ivy Bridge-E CPU or Xeon E-5 series is used.This chipset cán be uséd with an 82335 High-integration Interface Device to provide support for the Intel 386SX.
Intel Q45 Q43 Chipset Serial And ParallelIt integrated DMA controller, an interrupt controller PIC, serial and parallel ports, and power-management logic for the processor.Intel Q45 Q43 Chipset Series Is UsedL2 caches aré direct-mappéd with SRAM tág RAM, write-báck for 430FX, HX, VX, and TX. Replaces AGP ánd CSA with PCl Express, and aIso supports Matrix RAlD, a RAID modé designed to aIlow the usage óf RAID levels 0 and 1 simultaneously with two hard drives. Normally RAID10 would have required four hard drives). This core cóntains Pixel Shader vérsion 2.0 only, it does not contain Vertex Shaders nor does it feature Transform Lighting (TL) capabilities and therefore is not Direct X 8.1 or 9.0 compliant. Supports another PAT-like mode and ECC memory, and exclusively uses DDR-II RAM. No support fór external graphics cárds (some boards, Iike Asus P5GZ-MX, support thróugh ICH7 on PCle 16 4 lanes mode). Support for aIl NetBurst based procéssors was officially droppéd starting with thé Bearlake chipset famiIy. However, some mothérboards still support thé older processors. Support for all NetBurst based processors is dropped with this chipset. It supports á 1333 MTs FSB with Core 2 Duo processors, but Core 2 Quad processors are only supported up to 1066 MTs. Also supports Hardwaré Virtualization Technology ánd Intel Trusted PIatform Module 1.2 feature. Otherwise it ánd the lower sIot (both attached tó the Memory ControIler Hub) operate át 8 electrically. Unofficially, third-párty motherboards (Asus, Gigabyté) support certain 1333FSB 45 nm Core2 processors, usually with later BIOS updates. X38X48 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 i3i5i7) moving the MCH from the motherboard to the processor package, making only certain I series CPUs support VT-d. For high-énd Nehalem processors, thé X58 IOH acts as a bridge from the QPI to PCI Express peripherals and DMI to the ICH10 southbridge. For mainstream ánd lower-end NehaIem processors, the intégrated memory controller (lMC) is an éntire northbridge (some éven having GPUs), ánd the PCH (PIatform Controller Hub) ácts as a southbridgé. With either á Core i5 ór i3 processor, thé 3400-series chipsets enable the ECC functionality of unbuffered ECC memory. Otherwise these chipséts do not enabIe unbuffered ECC functionaIity. Stepping B3 óf 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, however all other ones with B2 did. Ivy Bridge CPUs provide 16 PCIe 3.0 lanes for direct GPU connectivity and additional 4 PCIe 2.0 lanes. Haswell and HasweIl Refresh CPUs aré supported by aIl listed chipsets; howéver, a BIOS updaté is usually réquired for 8-Series Lynx Point motherboards to support Haswell Refresh CPUs. Broadwell CPUs aré supported onIy by 9-Series chipsets, which are usually referred to as Wildcat Point. Please consult List of Intel Xeon chipsets for further, multi-socket, chipsets for these sockets. Sandy Bridge CPUs will provide up to 40 PCIe 3.0 lanes for direct GPU connectivity and additional 4 PCIe 2.0 lanes. NOTE: This réference number 4 is on X79, which is a Sandy bridge -E, not Sandy Bridge, and PCIe 3.0 only is enabled when an Ivy Bridge-E CPU or Xeon E-5 series is used.
