What Difference Of Processor Socket 775 Iga, Iga 1156, 1155 Iga, Iga 1150

Intel Socket or language Proccesor easy place always has a different
shape than the previous generation. This time I will discuss the type of
motherboard that has an LGA socket. LGA What the heck is that? LGA stands for
«Land Grid Array». Well here Motherboard LGA types that we will

1. LGA 775

LGA 775, also known as Socket T, is the processor
socket Intel’s desktop CPU (Central Processing Unit). LGA stands for «Land
Grid Array». Unlike earlier in the CPU socket commonly used, such as for
example redecessor Socket
478, LGA 775 do not have lubangsocket; instead, it has 775 pins that stand out
as a contact point touch at the bottom of the processor (CPU). The socket is then replaced by the LGA 1156 (Socket
H) and socket LGA 1366 (Socket B). FSB protocol AGTL + on the frequency FSB 133
MHz (533 MT / s), 200 MHz (800 MT / s), 266 MHz (1066 MT / s), 333 MHz (1333 MT
/ s), and 400 MHz (1600MT / s) , This socket CPU usage time to dominate the
world with the products Intel makes Intel very well known for their ad campaign
slogan «Intel Inside» of their product series include: Intel Pentium
4 (2. 60 — 3.80 GHz)

  • Intel Celeron D (2.53 — 3.60 GHz)
  • Intel Pentium 4 Extreme Edition (3.20 — 3.73 GHz)
  • Intel Pentium D (2.66 — 3.60 GHz)
  • Intel Pentium Extreme Edition (3.20 — 3.73 GHz)
  • Intel Pentium Dual-Core (1.40 — 3.33 GHz)
  • Intel Core 2 Duo (1.60 — 3.33 GHz)
  • Intel Core 2 Extreme (2.66 — 3.20 GHz)
  • Intel Core 2 Quad (2.33 — 3.00 GHz)
  • Intel Xeon (1.86 — 3.40 GHz)
  • Intel Celeron (1.60 — 2.40 GHz)

2. LGA 1156

LGA 1156, also known as Socket H or h2, is intended for Intel socket desktop CPU. LGA stands for «Land Grid Array» (when translated into Indonesian be: «land grid array»). Successor of this is compatible socket LGA 1155. LGA 1156, together with the LGA 1366, LGA is designed to replace the previous 775. If the LGA socket 775, the processor is connected to the northbridge using the Front Side Bus, LGA 1156 processors integrate the traditional features located on the northbridge to the processor it self. LGA 1156 socket allows the following connections are made from the processor to the rest of the system:

  • PCI-Express 2.0 × 16 for communication with the graphics card. Some processors allow these connections will be divided into two x 8 lines to connect the two graphics cards. Some motherboard manufacturers use Nvidia’s NF200 chip allows more graphics cards to be used.
  • DMI for communication with the Platform Controller Hub (PCH). It consists of a PCI-Express 2.0 × 4 connection.
  • FDI for communication with PCH. It consists of two DisplayPort connections.
  • Two memory channels for communication with DDR3 SDRAM. Supported memory clock speed will depend on the processor.

LGA 1156 socket processors and stopped around 2012, and was replaced by the LGA 1155 socket. LGA 1366 is stopped at the same time. 

Processor LGA 1156 Supported by:

All bersocket LGA 1156 processors and motherboards that are made today are interoperable, making it possible to switch between a Celeron, Pentium, Core i3 or Core i5 with integrated graphics and a Core i5 or Core i7 processor with no graphics. However, using a chip with integrated graphics on the motherboard P55 (in addition to the possibility of requiring a BIOS update) does not permit the use of the graphics processor on-board, and also, using the chips without integrated graphics on the H55, H57 or Q57 motherboard will not permit the use of graphics port motherboard.

3. LGA 1155

LGA 1155, also called Socket h3, an Intel microprocessor microprocessor socket device that supports Intel Sandy Bridge and Ivy Bridge. This socket is not compatible with the high-performance processor for desktop and server are designed for Intel LGA 2011 socket. LGA 1155 is designed as a replacement for LGA 1156 (known as Socket H). LGA 1155 has 1,155 protruding pins to make contact with the pads on the processor. The pins are arranged in a 40×40 array with a central void (the center of the socket vacated) 24×16; Further 61 pins are removed, 2 pin side by side with the center are emptied and 59 in groups around him, which resulted in a pin number 1600-384-61 = 1. 155. The processor of LGA 1155 and LGA 1156 socket is not compatible with each other because they have different socket notches. However, the cooling systems are compatible between both LGA 1155 and LGA 1156 socket, because as the processor, they have the same dimensions, profile and construction, and production of the same heat. integrated USB 3.0 support is present in Z75, Z77, H77, Q75, Q77 and B75 chipsets intended for Ivy Bridge CPU. See the list for a complete list of Intel chipset socket 1155 chipset. In the next generation, LGA 1150 and then has been launched to replace LGA 1155. Henceforth, LGA 1150 is divided into two kinds of chipset:

  • Sandy Bridge Chipset
  • Ivy Bridge chipset

Sandy Bridge Chipset

All Sandy Bridge chipset, except Q65, Q67 and B65, supports Sandy Bridge and Ivy Bridge CPUs, but must go through a BIOS upgrade first. Sandy Bridge based processors officially support up to DDR3-1333 memory, but in practice speeds up to DDR3-2133 memory have been tested and work successfully on this chipset.

The H61 chipset supports only a two-sided DIMM per channel memory and therefore limited to 16 GB instead of 32 GB as supported by other chipsets. On the motherboard with four DIMM slots, only four single-sided DIMM can be installed. Here is a table comparing the features of Sandy Bridge LGA 1155 chipset taken from Wikipedia:

4. LGA 1150

LGA 1150, also known as Socket h4, is a micro-processor Intel-compatible processor socket supporting series after series Haswell and Broadwell.
LGA 1150 is also designed as a replacement of the LGA 1155 (or what is known by the name Socket h3). LGA 1150 has 1,150 pins to make contact with the runway legs processor. The cooling system between the socket LGA 1155 and LGA 1156 socket is compatible with socket LGA 1150, because they have the same distance to each bolt hole (ie, at a distance of 75 millimeters). All motherboard with socket LGA 1150 support different types of video outputs (VGA, DVI, HDMI — depending on the respective model) and also supports Intel Clear Video Technology.
For LGA 1150 chipset codenamed Lynx Point. Intel Xeon processors for socket LGA 1150 chipset Intel C222, C224, and C226.
Here is a table that uses a chipset Intel socket LGA 1150:

Ok now you understand the differences socket Iga proccesor thanks


motherboard — Will socket 1155 cpu work in 775 mobo


5 years, 11 months ago

12k times

will INTEL Celeron G440 BOX (s. 1155) work in ASROCK G31M-S R2.0 (s. 775) motherboard?

I belive I heard that AM3 cpu can work in AM2 mobo is it the same case with intel.

  • cpu
  • motherboard
  • processor-socket


No, they are not compatible by any stretch of the imagination.

The AM2 socket has 940 contacts while the AM3 socket has 941, but otherwise, the arrangement of contacts is the same. AM3 CPUs have only 938 contacts and can be used in AM2 and AM2+ sockets (assuming a BIOS update) because they were made to be backward-compatible. AM2 CPUs do not work in an AM3 system because they do not have the newer controllers.

Intel on the other hand changes greatly with newer version. The socket 775 has 775 contacts while the socket 1155 has 1155 contacts. As you can see below, they are completely physically incompatible. In fact, even socket 1156 is incompatible with the (newer) socket 1155.

Socket AM2:

Socket AM3:

Socket 775:

Socket 1155:

Socket 1156:


No, they are entirely incompatable pin outs — intel doesn’t have backward compatibility between socket types — the 1155 has , well 1155 contacts and the 775 has 775 contacts, even if they have the same processor dimensions. It simply will not work.

NO they will not. AMD has released some chips that used the same physical socket with different specs that were sometimes compatible depending on chipset, cpu, and bios support.

No. There are several reasons for that. Here are two:

  1. LGA 775 CPUs have 775 pins while LGA 1155 CPUs have 1155 pins.

  2. LGA 1155 CPUs access the memory directly while LGA 775 CPUs let the northbridge handle the RAM.

No. The physical socket is dramatically different. See here and here. So is all the underlying componentry to support the CPU.

We redo the cooler from LGA 775 on LGA 1151 (» Project » Weekend») / DIY (DIY) / iXBT Live

Mini essay on how I converted a cooler from an LGA 775 socket to an LGA 1151. The method is universal and works for almost any LGA 775 coolers. it is quite possible to get by with a jigsaw or a saw for wood, and a piece of 3mm plywood.

What you need:

  1. LGA 775 cooler with its own mounting mechanism (plate). Snap-on options, with direct attachment to the motherboard — will not work.
  2. A piece of plywood or any other easy-to-work sheet material 2-3mm thick and 11x11cm or larger.
  3. 2.3-2.5mm drill and 3mm tap (If the mounting plate of the original cooler is not universal), M3 screws of the required length.
  4. Screwdriver, saw, ruler, pliers and other «normal» tools.
  5. Optional — vibration decoupling for the fan, laser cutter, synchrophasotron and more.

Initially, I was not going to redo anything, but the complete fan from the i3-9 processorThe 100F quickly changed my plans — in addition to being very noisy, its noise itself is not uniform “white”, but has a pronounced howl and buzz, even at low speeds. I discovered this already on Friday evening, when I was assembling a new computer for work — the stores were already closed, there were 3 days off ahead, but I wanted to finish the job. Over the years, I have accumulated a fairly impressive stock of used. processor heatsinks of various sizes — from Socket 1 (i486) to all-copper server solutions. The search process showed that heatsinks from LGA 2011, Socket 478, LGA 1366 and server ones are not suitable — they have a flat base, and the capacitors and inductors surrounding the socket interfere with the installation. The same applies to heatsinks from Socket 940/AM2/AM3 and so on. Strange as it may seem, at first glance, heatsinks from Socket 370/Socket A seem to be the easiest to install on the LGA 1151. But the heatsinks for these processors are quite compact, since they dissipate completely different powers, and are not suitable for modern processors. Therefore, I began to sort through the heatsinks from the 775 socket — choosing one that would have a protrusion from below, with which it would adjoin the processor, leaving room for coils and capacitors around the protrusion. The radiator was found quickly, it turned out to be manufactured by Cooler Master, the model is not known, as well as the fan with a sticker, and the mounting screws were missing — apparently, I used them for another purpose earlier.

Radiators are different — Copper, iron, dirty 🙂

The radiator has good fins, there is a copper core-heat distributor. In general, a strong mid-ranger, at least visually, is noticeably better than whale coolers from Intel and AMD for modern processors.

Before proceeding to the refinement process, I tried on the radiator to the motherboard — it doesn’t hurt anything and you can install it without problems.

Refinement of the radiator itself is as follows — since the mounting holes for the 1151 socket are located at the corners of a 75mm square, and for the 775 this square is 72mm in size, it is necessary to expand the lugs in the mounting holes. This can be done in different ways — at first I started cutting off the excess with a dremel, but assessing the softness of the metal, I quickly straightened the eyes with an ordinary flat screwdriver.

It seems like a trifle, these same 3mm, but putting a heatsink from LGA775 on LGA1151 will not work outright. Although I met Chinese mat. boards from SOYO, Inspur, which had 2 sets of holes — for LGA775 and LGA1155 radiators.

This is how the universal mounting plate for mounting on the back of the motherboard looks like. At retail, it costs literally a penny, and if your hands are not very sharpened for drilling and threading, then it is better to buy such a plate, and not to mangle the complete one from LGA775.

I was lucky with the mounting plate, it turned out to be universal, and to convert from 775 to 1151, you just had to move the latches. You may not be so lucky, therefore, there are several options:

  1. We drill new holes with a diameter of 2.3-2.5mm in the mounting plate and cut threads into them.
  2. Or drill through the plate with a 3mm drill bit and use the longer screws from the nut to fasten it.
  3. We buy or get the plate of the desired type.

I’m doing a test assembly, everything seems to be in order. So, you can cut out the adapter plate for mounting the fan.

Of course, the radiator was thoroughly blown and washed before installation — warm water and dishwashing detergent, together with a vibrating table, work wonders.

The oval slots are used to secure the anti-vibration barriers. In the case of direct fastening, the holes can be made round. If anyone needs a drawing in vector format, write, send.

The plate turned out to be quite simple — if you wish, you can print the drawing on a printer, stick it on plywood and cut it out with a jigsaw or a hacksaw. For myself, I decided to “tune” the plate a little — by adding all sorts of inscriptions.

Some «clumsiness» of the translation is deliberate — I did it on purpose in the style of «What are your proofs» Initially I wanted to make a complete cliché — with a chorus of balalaika bears, but was too lazy to draw.

We check on real hardware — this is a dead motherboard for socket 1155. Everything rises normally, it remains only to pick up the screws with the springs of the desired length.

By the way, this motherboard was really interesting — it had as many as 12 built-in COM ports, the management of which was scattered over completely unexpected places in the BIOS. For example, COM7 was enabled via Boot Option, and COM 5 via Hardware monitor.

There were no suitable screws in my “vintoteka”, I had to use M3 pins.

To «transform» them into screws, I used brass tips for M3 threads.

By enumeration, I picked up the springs of the desired stiffness.

These didn’t fit, they were weak.

But these are just right.

The fan was placed on anti-vibration silicone spacers. They really help to reduce the hum and vibration. It’s a pity that manufacturers put them on a regular basis only in expensive coolers, and even then, not in all.

Since there was no native fan on the cooler, I installed a rather quiet fan from ADDA with PWM control — AD0812UX-A7BGLbucks).

Everything, you can collect, assembled, installed, turned on, satisfied.

As a summary: I made a small comparison with a boxed cooler in terms of performance. When running the OCBase test for an hour, with a boxed cooler, the temperature turned out to be 59C at 2500 rpm, and with a redesigned 54C at 2300 rpm. The difference does not seem to be big, but the devil, as you know, lies in the details: The fan no longer howls, but rustles, the vibration from the fan is not transmitted to the motherboard and case, and they no longer serve as a sound amplifier resonator.
