Intel i945GC northbridge with Pentium Dual-Core microprocessor. 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).
At least one Asus board [which?] is known to have faulty BIOSes with corrupt ACPI IVRS tables; for such cases, under Linux, it is possible to specify custom mappings to override the faulty and/or missing BIOS-provided ones through the use of the ivrs_ioapic and ivrs_hpet kernel parameters.
Socket L was intended for enthusiasts who wanted server power in a desktop PC. It is just a re-branded Socket F that doesn't need special RAM, and may have only been used in the Asus L1N64-SLI WS Motherboard. Socket AM2+ 2007 AMD Athlon 64 AMD Athlon X2 AMD Phenom AMD Phenom II: Desktop PGA: 940 1.27 [9] 200–2600 MHz Separated power planes
There are a number of other companies (AMD, Microchip, Altera, etc.) making specialized chipsets as part of other ICs, and they are not often found in PC hardware (laptop, desktop or server). There are also a number of now defunct companies (like 3com, DEC, SGI) that produced network related chipsets for us in general computers.
A typical motherboard will have a different number of connections depending on its standard and form factor. A standard, modern ATX motherboard will typically have two or three PCI-Express x16 connection for a graphics card, one or two legacy PCI slots for various expansion cards, and one or two PCI-E x1 (which has superseded PCI).
At Intel, the authors of the PCI specification viewed the PCI local bus as being at the very centre of the PC platform architecture (i.e., at the Equator). The northbridge extends to the north of the PCI bus backbone in support of CPU, memory/cache, and other performance-critical capabilities. Likewise the southbridge extends to the south of ...
The number of contacts has increased, from 1700 (for LGA 1700) to 1851. [2] It uses the same dimensions and cooler mounting hole spacing as LGA 1700 , ensuring continued CPU cooler compatibility. It offers 20 PCIe 5.0 lanes (x16 for the expansion cards and x4 for storage) and an additional 4 PCIe 4.0 lanes for storage.
Comparison of some common motherboard form factors (pen for scale) A PC motherboard is the main circuit board within a typical desktop computer, laptop or server. Its main functions are as follows: To serve as a central backbone to which all other modular parts such as CPU, RAM, and hard drives can be attached as required to create a computer
