Socket 771 only supports processors from the manufacturer Intel. Motherboards with this socket were mainly created only for server systems, however, there are several options for ordinary motherboards.
Server motherboards for socket 771
The SuperMicro X7DBE motherboard is the same size as the EATX form factor. Intel processors in the amount of two pieces can be placed on this board. The frequency of the server bridge varies from 667 to 1333 megahertz. The processors that can be placed on this motherboard are the Xeon 5000 series. The chipset installed on the 771 socket motherboard corresponds to the Intel 5000 model.
Supported RAM - DDR2 FB-Dimm, on the motherboard sixteen slots for RAM. RAM can reach a maximum frequency of up to 667 megahertz. The power for the main connector of the motherboard goes to 24 pins.
Another server interface board is Intel S5000PSLSATA, the dimensions of which correspond to the SSI EEB marking. The number of placed sockets format 771 - two pieces. Just like the previous motherboard, there is a fixed processor frequency. And only the Xeon line of processes is supported. The chipset of this board is called Intel 5000.
Eight-slot RAM slots can support the DDR2 format. FB-Dimm is a specialized bracket that is designed only to work on server motherboards on socket 771. This memory works with a frequency of up to 667 megahertz. The maximum allowable total amount of RAM should not exceed 32 gigabytes.
ITZR G41GAL2
This motherboard corresponds to the micro ATX form factor and is built on the Intel G41 chipset . The board can accommodate up to two slats of DDR3 Dimm RAM, and the maximum achievable frequency is 1333 megahertz. There is an integrated graphics processor based on the Intel GMA X4500 model.
Processors under LGA 771
Since socket 771 processors must cope with a large amount of RAM, they are very powerful a priori. To work on this socket, Xeon 5000 series processors are used, as their architecture is able to cope with server tasks.
The Xeon E5345 model is built on a quad-core processor, whose frequency is 2,330 megahertz. The kernel is codenamed Harpertown and supports 64-bit format. The maximum bus frequency is 1333 megahertz, which provides accelerated data transfer to other devices. The second-level memory cache is eight megabytes, which allows you to allocate two megabytes per core.
As for the technological process, there are two processor options - 45 nanometers and 65 nanometers. The smaller the process technology, the more efficient the processor. The energy consumption does not exceed 80 watts, and the maximum allowable temperature corresponds to 65 degrees Celsius.
The next processor for socket 771 is called Xeon 5030, and its core is called Dempsey. The dual-core processor is capable of operating at frequencies up to 2,660 megahertz. The 65-nanometer process is capable of processing data at a frequency of 667 megahertz. A second-level cache with a total size of 4 megabytes is divided into two cores of two megabytes.
The temperature with which you can work should not exceed 68 degrees, and the power consumption is 95 watts.
Install 771 sockets in 775
So, it's time to figure out how to move the processor of one socket to the motherboard of another.
The first step is to choose a motherboard with a 775 socket, which is capable of working with processors of the Xeon model. Step two - download the firmware for BIOS, which was created to modify the motherboard. The manufacturer’s website has instructions on how to flash BIOS without affecting the operating system.
Next, you need to examine the processor: if it has cuts and soldered contacts, then there will be no problems with the installation. In the absence of soldering, you can simply install a special sticker on the desired contacts. After that, you will have to remove the keys from the board. If you do everything carefully, then the performance of the motherboard will not suffer. The necessary keys are placed on the sides of the processor. They are cut with a simple clerical knife.
Possible nuances
Sometimes, after flashing the BIOS and installing the processor in the motherboard, malfunctions can occur. One of these problems is detected on new operating systems Win 8 and beyond, as they may require certain processor functions. To resolve these problems, you need to check the BIOS version, if it is out of date, you need to update it or reflash it. The main thing is that the firmware indicates microcodes for the processor model.
A problem may arise with cooling - the cooler will work at full capacity. The reason for this problem lies in the BIOS, where the aggressive cooling settings are set. It may also be that cooling cannot handle such a powerful processor.
Another problem is expressed as a black screen at startup. The fault is the incorrect installation of the processor in the socket. To fix this problem, you need to check if the keys are cut to the end. If everything is correct, but the screen is still black, then it is worth checking the functionality of the old processor. Perhaps the problem lies in the damaged socket.
