Description

A new 4-processor server PCB structure device

technical field

The utility model relates to the technical field of computer servers, in particular to a novel 4-processor server PCB structure device.

Background technique

In the field of multi-channel servers, functional reliability is crucial. Recently, a new Mill Brook Memory Buffer module has been launched for DDR3 Intel (the buffer chip is the memory buffer of Mill Brook). Larger power can be achieved in the PCB space to achieve more functions, which makes the components need to be densely arranged, and the structural layout of each component should be optimized. The current PCB size is relatively large, and the boarding cycle is long during the PCB development process, and the debugging is complicated. higher cost.

Contents of the invention

The technical task of the utility model is to solve the deficiencies of the prior art and provide a novel 4-processor server PCB structure device.

The technical scheme of the utility model is realized in the following manner. This novel 4-processor server PCB structure device has a structure including a main board, on which 4 CPUs are installed side by side, and on the main board on the side of the CPU, through a connector A memory board is connected, the connector is arranged on the back side of the memory board, memory and Mill Brook Memory Buffer modules are arranged on the front of the memory board, and screw fixing holes are arranged at the four corners of the memory board.

The main board and the memory board adopt the Board to Board stacked board connection structure.

There are 2 connectors on the memory board, 8 memory devices, and 2 Mill Brook MemoryBuffer modules.

There are 4 memory boards connected to the motherboard.

The CPU fixed on the mainboard is a Nehalem-EX processor.

Compared with the prior art, the utility model has the following beneficial effects:

A novel 4-processor server PCB structure device of the utility model has the characteristics of reasonable design, simple structure, and convenient PCB wiring; it supports larger capacity and high-performance memory, supports high-power processors, and realizes more functional requirements; the main and auxiliary boards The structure can better solve the problems of long board-making cycle, complicated debugging, and high cost in the development process of large-sized PCBs; the flexible use of memory board modules can meet the needs of different customers for different performance indicators of the system. The memory board and the computer main board adopt a Board to Board stacked board structure, which reduces the overall height of the PCB compared to the memory riser card structure, makes full use of the entire system space, and solves the problem of the large space occupied by the MillBrook Memory Buffer module, improving system performance index; and the utility model also has a good heat dissipation structure, and the heat dissipation effect is ideal.
