USB devices

This chip typically gets hotter as processor speed becomes faster, requiring more cooling. It includes all the standard legacy peripherals, along with fan control and monitoring pins. It also has a small battery for safekeeping the motherboard configuration and clock memory. Optional Audio Chips The motherboard may have a couple of empty chip spots on the board, unless you order the version that includes the higher-performance onboard audio. As CPU speeds increased over time, a bottleneck eventually emerged between the processor and the motherboard , due to limitations caused by data transmission between the CPU and its support chipset.

One important thing to look for on a motherboard is to make sure there is plenty of physical clearance around the processor, in case you want to put on a bigger heatsink. Onboard Speaker and Battery Instead of needing to cable to a speaker in the case, the motherboard has a small speaker mounted onboard. Modern Intel Core processors have the northbridge integrated on the CPU die, where it is known as the uncore or system agent.

Northbridge (computing) – Wikipedia

Because different processors and RAM require different signaling, a given northbridge will typically work with only one or two classes of CPUs and generally only one type of RAM. This page was last edited on 8 Octoberat In other projects Wikimedia Commons.

Processor Socket This board supports Celeron or Pentium III processors in a variety of package technologies with different thermal characteristics. The motherboard also has quite a few manufacturing options, mainly dealing with audio and networking. The floppy disk connector continues to be a standard part of all motherboards.


The northbridge plays an important part in how far a computer can be overclockedas its frequency is commonly used as a baseline for the CPU to establish its own operating frequency. Encyclopedia of computer science and technology. Post a Comment Comment.

Intel – datasheet pdf

Increasingly these functions became integrated into the CPU chip itself, [3] beginning with memory and graphics controllers. The northbridge was replaced by the system agent introduced by the Sandy Bridge microarchitecture inwhich essentially handles all previous Northbridge functions.

Front Panel Connectors Normally, the front panel is just ymch way to drive some indicator lights from the motherboard. The northbridge would then be connected to the rest of the chipset via a slow bridge the southbridge located south xgp other system devices as drawn.

PC Motherboard Technology

This motherboard has a few extras. Power Supply The Voltage Regulator Module was discussed in an earlier section, and this motherboard has the VRM and several analog components capacitors, resistors, etc. This site may earn affiliate commissions from the links on this page.

Hopefully, the proceeding pages have given you an appreciation for the years of effort that have gone into bringing us to the point where such a powerful computer is contained on a single board. You may unsubscribe from the newsletter at any time. Computer Science portal Electronics portal.

aggp This memory is organized as a 4 MB cache that acts as a high-speed buffer for graphics data stored in the system memory. The bus speed depends on which processor is used.


As CPU speeds increased over time, a bottleneck eventually emerged between the processor and the motherboarddue to limitations caused by data transmission between the CPU and its support chipset. Articles needing additional references from January All articles needing additional references.

There is a connector on the motherboard for attaching to the second USB controller. However, the best place to put the 2 extra USB ports is on the front panel. A northbridge or host bridge is one of the two chips in the core logic chipset architecture on a PC motherboardthe other being the southbridge. On nForce4 boards it was marketed as a media communications processor MCP. Retrieved January 4, The CPU would be connected to the chipset via a fast bridge the northbridge located north of other system devices as drawn.

There are a few chipsets that support two types of RAM generally these are available when there is a shift to a new standard. New York, NY [u. Unlike the southbridge, northbridge is connected directly to the CPU via the front-side bus FSB and is thus responsible aagp tasks that require the highest performance.
