The best processors on the "Socket 775"
Intel has long been engaged in the release of processors. During its existence, it has produced thousands of new chip models, which have been enjoyed by many users. Their classification has become much easier, but because of the large variety of options on the market, which are practically the same from each other, it has become more difficult to understand them.
Before we learn what "Socket 775" is, when and how it appeared and what has introduced something new in the generation of processors, let's deal directly with the meaning of this term.
Before understanding the generations and types of processors, you need to understand what a "socket" is. From English, the term translates as "connector". In the technical field, it means a software interface that provides data exchange between chips. At the same time, the process itself can take place both on the same machine, and on different ones connected to each other through the network.
In computer terminology, a socket is called a socket for the CPU. This is the place on the motherboard where the chip is placed.Previously, processors were soldered, so their further replacement was very difficult (as a whole, almost impossible). The connector helped to solve this problem. Now you can change the chips, upgrade them or repair.
The socket for the processor can be filled with both the crystal itself and the board on which this chip is located. As we will find out later, each socket has its own format and involves the installation of a certain type of processor. Physically, sockets can be distinguished by the number of contacts, the cooler's fixing distance, sizes, etc. As a result, it becomes clear that it is almost impossible to install different processors in one connector.
It should immediately be said that by 2017 the Intel "Socket 775" is significantly outdated. It will soon be 15 years old, which means no modern motherboard will accept it as before, with “open arms”. It is also interesting that before this connector format appeared in 2004, 15 sockets have already entered the market. Some still acted at that time, others were forgotten, like our hero now.
The first was a socket with a loud name Socket 1. It had only one processor variant - Intel 80486, which became famous back in 1989.Later, 7 more generations of sockets appeared. After Socket 8, the company decided to think wisely with the names and released several variants of Socket (370, 423, 278, etc.), which had long since passed to Pentium and Celeron.
Hero of 2004
This year, Socket T or LGA 775 became known to the world. Then the appearance of such a format was accepted by the audience as revolutionary. The generation of processors has changed, and with it has changed the architecture of a modern PC. Almost all the numbers in the specification were replaced, the graphics card bus, expansion cards, cooler standard, memory, power supply, etc. were changed.
Both powerful 775 socket processors and fairly simple models for ordinary users have appeared on the market. Basically, this connector could put the model Pentium 4, EE and D, Celeron D, Core 2 Duo, Extreme, Celeron, Xeon Series 3000, Core 2 Quad.
So, the new socket "Socket 775" worked with processors whose frequency was in the range 1.8 - 3.8 GHz. The system bus frequency range is 533-1600 MHz. The connector turned out to be universal, it was located not only in PCs, but also on workstations and received a standard size - 3.75x3.75 centimeters. Therefore, contacts on it could be placed more than half times. Also, processors based on this socket have acquired low heat emission, since alloys with low resistivity were used for them.
Disappeared from new products and marking frequencies. Now only the production number was indicated above. The marking of processors has increased, which, although it could first confuse the buyer, but later helped to better understand the offers on the market. Conroe, Yorkfield, Kentsfield, Wolfdale, and others appeared among the codename names for the nuclei.
Nevertheless, these names were known more to those who developed micro-architectures. The types of cores became the basis of the technical process and, regardless of the type of the processor itself, could be used in the chip.
The Intel 775 socket was also developed for the Core 2 Duo, Quad and Xeon. These brands of the processor are presented at different stages of evolutionary development. But there are no jumps in this area. It is noticed that systematically technical process is approaching 45-nm. And initially it was assumed that the development will be aimed at desktop processors for ordinary users, but, for example, Core 2 Quad refers more to server platforms and systems with critical work.
As usual, indexes and postscripts indicate varieties. If the name of the processor contains the letter E, then it is clear that it belongs to Core 2 Duo and, accordingly, has two cores. If Q is indexed in the index, then this is a quad-core quad series.Intel Xeon, which is also equipped with "Socket 775", is designed for server processors and received two indices: L is responsible for dual-core models, and X is for quad-core ones.
In turn, you can consider each model range in more detail. For example, Core 2 Duo has a line of budget chips E4xxx and E6xxx. Among them, it is difficult to name the best model, since they are made using the outdated 65nm process technology. Expensive options can be found in the E7xxx and E8xxx lines. It is caused by the fact that the technical process here got to the mark of 45-nm. Changed cache memory and clock speeds. The Core 2 Quad series also has a similar classification principle. The cheapest is the Q6xxx line with the 65nm process technology. Q8xxx and Q9xxx - at 45nm.
To understand how the connector has changed and the company's overall policy, consider motherboards based on Intel 915.
The Prescott core for our processors is a familiar thing. Such processors received 1 MB of memory for the second-level cache. They demanded more power consumption, and accordingly, the company had to think about how to change the overall strategy for the production of the connector and the chip for it.
The novelty has changed the understanding of the socket habitual for that time. So, instead of legs, round stripes appeared on which the contacts were placed. The legs went to the motherboard.And if earlier, many believed that the mother was a “girl” and the processor was a “boy”, now the situation has turned out exactly the opposite.
Accordingly, it was necessary to change the attachment mechanism, as it was necessary to press the connector mechanism itself to the contacts on the chip. To do this, create a metal lever frame. It is difficult to talk about convenience - who has managed to adapt. At one time it was convenient to install the processors, like cartridges in the console, now I had to fix the crystal with a lever. The only problem that later became known to users is the short life span. It turned out that it was possible to disconnect and connect processors only up to 20 times. After that, the contacts were erased.
We had to develop a new mount for the cooler. If earlier the radiator could be attached to a socket or frame on the board, now special holes have been made for it in the board itself. This caused problems with the selection of larger cooling systems. In addition, the coolers were made at once with four connectors, for better reliability. Also, the fans have four contacts to connect.
Graphics card location
Motherboard 775 socket also acquired a new PCI Express bus. At that time, many wondered if it was advisable to install a high-performance tire. It is clear that over time, this format has manifested itself quite well and in many ways has become an excellent prospect. The throughput increased from 133 to 500 Mb / s.
For video cards, the bus was also changed to PCI Express 16x. The capacity in this case plays a huge role, so the transition to this format was more than ever the way. The company even decided to completely abandon AGP 8x, which is why newer models like Intel 915 and 925 no longer support the previous format.
The capacity of the new tire was 8 Gb / s, which gave prospects for the future and, in principle, the opportunity to experiment. New tire changed and looks. She has become much shorter. At the same time, it did not lose the ability to transmit more electrical power, which made it possible at last to eliminate additional power contacts.
The new chipsets with the updated 775 socket DDR3 socket were not immediately supported. First, the transition from DDR 400 to DDR II was realized. He was expected, he was talked about for a long time, so nothing new or surprising happened.The backward compatibility of DDR I also remained. But it would be strange to use an outdated standard of memory when new modules appeared on the market.
Outwardly, they looked almost the same. The module received 240 contacts, and the notch slightly shifted, which is why such plates could not be installed in an outdated slot. They reduced the memory voltage to 1.8 V. Therefore, in addition to popularity among PC users, there was also a need to install modules in laptops.
Support directly DDR3 began only from the moment of their appearance - at the end of 2008. On the basis of this memory and our socket are known Asus P5Q3 Deluxe and MSI G41M-P28. DDR3 was distinguished by low power consumption, which was caused by low voltage - from 1.8 to 1.5 V. The technical process was changed, etc.
Naturally, motherboards with "Socket 775" at one time was a lot. Now it is quite difficult to find models, since a lot of time has passed since 2004, and after that a huge number of new connectors have appeared, although this one is considered legendary. Rather, it is due to the fact that it was revolutionary in its own way, brought many innovations that significantly influenced the strategy of developing computer peripherals, and after that, and productivity.
MSI 915P-NEO2 is one of the motherboards based on the LGA775 platform. She supported the Intel Pentium 4. There was also another motherboard, EliteGroup PF4 Extreme, about which very few people know now. Also worked under LGA775. Do not stand aside and the company Asus. The 775 socket fits in the Asustek P5GD1 model, which also supported the Pentium 4 and Celeron. In general, there were many such models, and everyone could find the best option for LGA 775.
