From the outside, Intel’s desktop CPU roadmaps have been a bit murky over the last year or so. We have confirmation that Intel’s 14th Gen Raptor Lake refresh is coming in October. Meteor Lake was initially expected in its place, before it was cancelled in favor of Arrow Lake.
Whatever Lake(s) ends up appearing in 2024, we’re sure to be getting a new LGA1851 socket to replace the nearly two year old LGA1700 socket that’s present on current 600-series and 700-series motherboards.
Igor’s lab has been on a roll. Following its performance projections for Arrow Lake, Igor has now revealed a treasure trove of information regarding the LGA1851 socket, which will accompany not just Arrow Lake processors, but surely a generation beyond that. The LGA1851 socket will be present on Intel’s 800-series chipset motherboards, presumably debuting in the form of Z890.
As the name suggests, LGA1851 comes with 151 more pins than the current LGA1700 socket does. The extra pins are primarily there to improve support for PCIe 5.0 SSDs. This means 800-series boards will support a full bandwidth PCIe 5.0 x16 slot for a graphics card and a PCIe 5.0 x4 NVMe SSD at the same time. The CPU should support a directly connected secondary PCIe 4.0 x4 SSD too.
That all but matches AM5 motherboards with Extreme chipsets. In the case of AMD though, a secondary PCIe drive can run at PCIe 5.0 speeds too, albeit in a x8/x4/x4 configuration. Current LGA1700 boards will support a PCIe 5.0 drive, but that means sharing bandwidth with the primary x16 slot, even with only one drive installed. LGA1851 is a definite improvement in that regard.
Now let’s talk about the socket’s dimensions, and what it means for current CPU coolers. The good news is the X, Y, and Z dimensions are the same, and therefore the motherboard mounting holes likely will be too.
But the dynamic pressure maximum has nearly doubled, from 489.5 N to 923 N. That means LGA1851 CPUs will require more downward pressure from CPU coolers. In turn, that means many coolers will require LGA1851-specific mounting kits.
There’s another interesting thing to note. Intel has faced some issues with bowing of LGA1700 CPUs, yet Igor’s Lab notes that enquiries regarding transient bend strain should be directed to local engineers. This would refer to socket manufacturers such as Lotes or Foxconn. Though the mechanisms look mostly the same as they currently do, manufacturers will certainly be implementing tweaked mounting mechanisms. This should eliminate any warping issues which could be exacerbated with increased downward pressure.

It’s a little disappointing not to get something like the LGA2066 mechanism with retention clips on each side of the CPU.
Maybe it’d cost 2.764 cents more to make? Personally I’m a big fan of AMD’s Threadripper mounting mechanism, but that requires an additional hex screwdriver and it’d never be implemented on budget B810 or B860 motherboards for cost reasons.
So while the LGA1700 and LGA1851 sockets will look similar and have similar dimensions, they’re essentially completely different in terms of CPU compatibility and probably cooler compatibility too.
Upgrading will come at a steep cost. DDR4 support is to be axed, so if you buy a new Arrow Lake CPU, you’ll need a new motherboard, DDR5 memory and potentially a new cooler (or at least a mounting kit) as well. AMD buyers took the pain with a similar requirement at the time of the launch of the AM5 platform. Though cooler support carried over from AM4, buyers were hurt by the horrendous pricing of DDR5 memory at the time.
Assuming Intel sticks to its trend of retaining socket support for two generations, the good news is that 800-series boards with the LGA1851 socket should support Lunar Lake CPUs too.
It’s no leap to assume we’ll see LGA1851 900-series motherboards accompanying Lunar Lake, though that’s looking like a 2026 proposition at best. Start saving, even though AI might kill us all by then anyway.

Chris’ gaming experiences go back to the mid-nineties when he conned his parents into buying an ‘educational PC’ that was conveniently overpowered to play Doom and Tie Fighter. He developed a love of extreme overclocking that destroyed his savings despite the cheaper hardware on offer via his job at a PC store. To afford more LN2 he began moonlighting as a reviewer for VR-Zone before jumping the fence to work for MSI Australia. Since then, he’s gone back to journalism, enthusiastically reviewing the latest and greatest components for PC & Tech Authority, PC Powerplay and currently Australian Personal Computer magazine and PC Gamer.
Chris still puts far too many hours into Borderlands 3, always striving to become a more efficient killer.

What is LGA 1700 motherboard chipset
Intel chipsets are used to build motherboards for Intel processors.
Each chipset has its own set of capabilities. However, in order for you to use these features and capabilities, motherboards must explicitly support them. Check our LGA 1700 socket motherboard list that has this characteristics and capabilities
12th and 13th generation Intel Core processors require a motherboard with a LGA 1700 socket and a 700-series or 600-series chipset.
The Intel 700-series chipsets were designed primarily for 13th generation Core processors, but they are also compatible with all 12th generation Core processors. Because 600-series chipsets were built for Core processors of the 12th generation, they may limit the capabilities of a 13th generation machine.
To overclock 12th and 13th generation CPUs, you’ll need a motherboard with overclocking capabilities
CPU overclocking is commonly supported by motherboards equipped with the Z790 and Z690 chipsets. Otherwise, a motherboard with one of Intel’s other 700- or 600-series desktop chipsets will suffice (e.
g., H670, B660, or H610). The W680 and Q670 chipsets are designed for workstations and corporate applications. These chipsets aren’t seen on many standalone motherboards.
LGA 1700 is the first significant modification in Intel’s LGA desktop CPU socket size since the introduction of LGA 775 in 2004, and it is particularly significant for the consumer-grade CPU sockets. Because the size is bigger, the way the heatsink attaches to the CPU has to change. This means that older cooling solutions won’t work with LGA 1700 motherboards and CPUs.

How to find out the motherboard socket on a computer
The choice of a motherboard or processor cooling system primarily depends on the socket.
Let’s figure out what it is, as well as how to check and determine it.
What is a motherboard socket and where is it located
A socket is a socket where a processor is installed. It is located on the motherboard and is located to the left of the RAM slots. Some processors, such as the Intel Xeon, have support for 4-channel RAM. In such cases, the socket on the motherboard will be located between the RAM slots.
Sockets differ from each other not only in shape, but also in the pinout of contacts — the location of small metal legs. Through them, the processors are connected to the motherboard. Some contacts are responsible for the operation of the CPU, others for data transfer via the PCI-e bus, others for the exchange of information between RAM, etc.
Why Intel and AMD are changing the sockets of their processors
It would seem that using the same socket is beneficial for everyone. Manufacturers of processors and motherboards could save on production, and it would become easier for buyers to choose computer components.
Intel and AMD are well aware of the benefits of using a single socket, but they cannot realize it. The problem is that there is no way to improve CPU performance without changing its layout. Processor manufacturers are forced to constantly change the architecture and geometry of their devices in order to increase their power.
In addition, there are things that Intel and AMD can not influence. For example, this applies to a new type of DDR5 RAM, the logic of which is very different from DDR4 — it was impossible to teach processors to work with a new type of RAM without changing the socket. It was necessary to rework not only the pinout of the contacts, but also the memory controller. Such global changes also force manufacturers to change the socket.
Actual sockets
Conventionally, they can be divided according to the type of RAM. Current Intel processor sockets for DDR4:
- LGA 1151;
- LGA 1151 V2;
- LGA 1200.
Intel’s latest socket is the LGA 1700.
Processors with this socket can work with both DDR4 and DDR5. This is possible due to the fact that the blue engineers managed to implement two memory controllers in their new CPUs at once.
Current AMD processor socket for DDR4 — AM4. At the end of 2022, the Reds released a new generation of Ryzen 7000 CPUs with socket AM5. It only works with DDR5 memory. AMD either did not want or could not implement two controllers at once, as its competitor represented by Intel.
How to find out the motherboard socket
There are several ways to find out the socket, and we will describe them all, from the simplest to the most laborious.
Method one — just google the name of the processor
The easiest way to understand which socket is on the motherboard is by the name of the processor. To find out, go to the Windows control panel and click the «system» button. Opposite the word «Processor» will be its name.
If you cannot start the computer, you will have to disassemble it.
You will need to unscrew the side cover, remove the cooling system and wipe the thermal paste from the processor with a dry cloth. The name will be written right on it.
If you bought a BOX version of the processor, then you may have left the box or technical documentation. They always contain information about the CPU.
To find out what socket your PC has, enter the name of the processor in the search box. Go to the official Intel or AMD page and go to the specifications. There you will find your processor socket.
Sometimes companies write «processor socket» or simply «socket» instead of «socket». Please note that we are talking about the same thing.
Method two — Google the name of the motherboard
If you don’t know the name of your motherboard, then press the Win+R keyboard shortcut on your computer. In the panel that opens, type msinfo32 and press the Enter button. You will see the «System Information» window. Opposite the word «Model» will be the name of your motherboard.
By the way, in the same window you can find out the name of your processor.
If you cannot turn on the computer and enter the operating system, then, as in the case of the processor, try to find the box from the motherboard or the technical documentation that came with it. If the box or documents are still not found, then you will have to disassemble the computer and climb inside.
After you know the name of the board, enter it in the search box and click the «find» button. Next, go to the official page of the manufacturer, and in the characteristics you will see the desired parameter.
It may be easier to find out the processor socket on the motherboard in the online store. Manufacturers on their websites may not translate the parameters into Russian or indicate some kind of fee. However, to determine the socket, it is recommended to visit the official pages of manufacturers. There will definitely be no errors or typos in them.
Let’s look at an example of how to find out which socket is on the motherboard.
Let’s say your board name is «ASUS TUF GAMING B550M PLUS». We enter these words and numbers in the search bar, and then click «find». The first link belongs to the Asus website, the official manufacturer of our board. We click on it and on the main page we see the phrase «AM4 connector».
Method three — install the monitoring program
Now we will tell you how to find out the motherboard socket through a computer, namely with the help of such utilities as CPU-Z and AIDA64. They are free and work on all Windows systems, including versions 10 and 11.
These programs are used to monitor computer components: analyze temperature, power, voltage, etc. They have about the same features, so download and install the one you like best.
To find out the processor socket using CPU-Z, run the program and go to the «CPU» tab. It usually opens by default. There will be a line «Package» or «Processor package». It is in it that you can see your socket.
The algorithm for AIDA64 is slightly different.
First, launch the utility and click on the «Computer» section in the left column. Next, go to «Motherboard» and select «Motherboard» from the list. At the bottom opposite the word «CPU socket» will be the name of the socket.
Method four — inspect the motherboard
This is the most extreme case and only resort to it if:
- You cannot start the computer;
- There is no box and documentation from the motherboard.
- The CPU is missing.
Your task is to carefully inspect the board and try to find inscriptions similar to the following:
- h410M D3H;
- PRIME B450-PLUS;
- Z690 PHANTOM GAMING 4 etc.
These are all motherboard names. In 99% of cases they are printed on textolite, but their location is different for all models. On some boards, the name is written on the top next to the RAM slots, on the second boards, on the bottom near the PCI-e connectors for the video card, on the third ones, they are located in the very corner, etc.
Finding out the name of the board, you can easily find out what socket you have.
Also, manufacturers always write additional information on the boards. For example, the numbering of SATA connectors. Often they also print the name of the sockets. If you find it, then you don’t have to drive in the name of the board on the Internet.
