If you want to know the answer to this question, you are probably trying to assemble your PC, and you must be looking for a way to connect the CPU components of your computer. In this article, you will learn better about some of the important motherboard slots on your PC.

Furthermore, you will know about the importance of PCIe slots, ZIF socket, and also the role of the northbridge motherboard. Finally, you will also know about the slot in the motherboard, which has direct access to the north bridge.

How To Know What Motherboard Slot Has Direct Access To The North Bridge?  

How To Know What Motherboard Slot Has Direct Access To The North Bridge 

To know about the motherboard slots having better access to the north bridge and the south bridge, you will need to know individually of both of these chips. Every motherboard comes with these two chipsets. Basically, these two chips are responsible for connecting the different slots of the motherboard to other components of the computer.

The north bridge or the north board is responsible for connecting all the components of the PC with the CPU slots. These components mainly include PCIe cards, RAM, AGP cards, and FSB in the front. According to the PC Magazine, “The high-speed part of a common chipset architecture in a computer. The Northbridge is the controller that interconnects the CPU to memory via the frontside bus (FSB). It also connects peripherals via high-speed channels such as PCI Express. The Northbridge may include a display controller, obviating the need for a separate graphics card.”

On the other hand, the remaining parts of the PC get connected to the south bridge or the south board of the motherboard. In this case, as per the PC Magazine, “The Southbridge controller handles the remaining I/O, including the PCI bus, parallel and Serial ATA drives (IDE), USB, FireWire, serial and parallel ports, and audio ports. Earlier chipsets supported the ISA bus in Southbridge. Starting with Intel’s 8xx chipsets, Northbridge and Southbridge were changed to Memory Controller and I/O Controller.”

Here are some of the major motherboard slots that you will need to know of:

Importance Of The PCIe Slot

The PCIe slot plays an important role in the north bridge section of the motherboard. This slot is a high-speed channel that helps in connecting all the peripherals of the computer. The north bridge helps to connect the CPU with the PCIe slot. No matter which type of PC you are using, the role and importance of the PCIe slot remain mostly the same.

PCIe slots also come with different configurations. If you want to configure your motherboard’s PCIe slot, you must try with x1, x2, x8, and x16 configurations. Each of the numbers in these configurations represents the amount of input/output. Although these are standard configurations, there are also different configurations of PCIe slots.

The Importance And Role Of ZIF Socket

ZIF is also known as Zero Insertion Force socket. The ZIF socket is mainly responsible for accepting PCA chips and pin grids arrays. Suggestive of the name, you will feel much easier if you use a ZIF socket since you will not need to insert any force while you connect the PGA chips. You will not have to put any force on the motherboard.

However, if you use excessive insertion force on the motherboard, it can weaken the motherboard and might even break it. According to Techopedia, “The ZIF socket was specifically designed to combat the issue of IC and pin damage due to insertion and removal. But the downside is the large footprint of a ZIF socket which is due to the lever locking and unlocking mechanism.”

The North Bridge Motherboard And Its Importance

The motherboard northbridge helps to connect the CPU through the FSB. This is to facilitate the processes of the PC that requires higher computing performance. The north bridge is also responsible for connecting the south bridge to the CPU system. The north bridge is also known as the memory controller hub. However, with recent developments, the north bridge is on the verge of getting replaced with the coming of the AMD64 architecture.

According to Techopedia, the north bridge motherboard “handles the faster components on the motherboard, including RAM, ROM, basic input/output system (BIOS), accelerated graphics port (AGP), PCI Express, and the southbridge chip as well as the CPU. It also controls the CPU cache if it is located on the motherboard.”

Motherboards that come with accelerated graphics port is a better option for high-end graphics cards, as they perform better on them. Previously, you would have to insert graphics cards in PCIe slots, but with the AGP, you would not need to do it.

After high-end graphics cards came into the market, it became hard for motherboards to deal with bottlenecks in performance. This is the major reason why AGPs came into the picture. Furthermore, they also connect directly with the north bridge motherboards.

Hence, if you want to connect the northbridge to a slot in the motherboard, you would need to connect to the accelerated graphics port (AGP). This helped a lot in connecting high-end graphics cards with the motherboard for better gaming and graphics work in the computer.

According to Techopedia, “AGP can provide dedicated communication between the processor and slot. It increases clock speed and also uses RAM to copy the graphics information before loading. Moreover, AGP keeps refreshing the display screen of the monitor to keep boosting the pixel powers.”

Summing Up:

Hope you have found your answer, in this article, to the question, “What motherboard slot has direct access to the north bridge?” The answer to that is AGP or accelerated graphics port. This slot is really a good option to connect high-end graphics cards, as it creates fewer problems and bottlenecks. Do you know of any more advantages and uses of the AGP?
