Computer installation and assembly host first step: Install CPU processor
The current market, Intel processors are mainly 32-bit and 64-bit Celeron and Pentium two (core is currently listed,

Recently, thermaltake (TT), the world's leading provider of overall PC cooling solutions, has launched a new integrated water-cooled radiator bigwater. This water-cooled radiator and Its Matching shark chassis have attracted a lot of attention since it was launched. As a product in the high-end heat dissipation market, the supported platform not only supports the socket 478, amd K7, and K8 proces
early Pentium 4 series processors, with a pin number of 478 pins. The Pentium 4 processor area of Socket 478 is small and the pins are very tightly arranged. Intel Corporation's Pentium 4 series and P4 Celeron series all use this interface, the current CPU has been phased out of the market.
However, Intel launched a new socket 478 interface in early 2006, which is a dedicated interface between Intel's core processor core duo and Core Solo, with the
specifications of the video slot, almost all of the current market for memory and graphics card, upgrade capability is excellent. Based on the Via PT880 ULTRA/VT8237A chipset, supports the LGA775 package of series processors, FSB bus frequency can support up to 1066MHz, in line with the current mainstream processor needs. and four-phase power supply design, for the current mainstream Intel
of the DEP protection function, in addition to upgrading the system to SP2, your CPU must also support the DEP technology. Currently, common 32-bit processors (such as P4 Northwood) do not support NX. The CPUs supporting this technology mainly include AMD's 64-bit processors (Athlon 64 and AMD Opteron ), and Intel's Apsara series CPU and J series P4 Prescott. It is said that companies such as nVIDIA, VIA,
Windows for destruction. Hardware Implementation DEP is a feature of some Dep compatible processors that prevents code execution in the memory area marked as a data storage area. This function is also called non-execution and execution protection. Windows XP SP2 also includes software implementation DEP, which aims to reduce the use of the exception handling mechanism in windows. Unlike anti-virus programs, the hardware and software Dep technology is
frequency of the CPU. We need to know that the actual CPU operating frequency should be consistent with the standard operating frequency, but the reason is that the adjustment frequency of the motherboard of each manufacturer is inconsistent, the frequency here has a certain error. If the difference between the two frequencies is too large, the standard operating frequency is 2.40 GHz, and the actual operating frequency is 3.21 GHz, then you will encounter CPU overclocking, if you purchased the
phenomenon occurs, it is basically possible to conclude that the processor is having a problem.
So what do we need to pay attention to when installing the CPU? After the CPU processor has failed, which aspects should we check the troubleshooting? In general, we can follow the following steps to judge and exclude.
The first thing to note about the installation process is:
First, check the CPU processor is installed in place
The current processor slot design is very standard, the motherboar

Summary
Multicore processors are also known as on-chip multi-processor (chip multi-processor,cmp). Since 1996 Stanford University first introduced the on-chip multi-processor (CMP) idea and the first multi-core architecture prototype, to 2001 MM launched the first commercial multi-core processor POWER4, and then to 2005 Intel and AMD Multicore
radiator, in addition to the selection of materials, the use of excellent radiator fin material, using tower-type dual-guide heat pipe, aluminum base, with 9cm cooling fan, this collocation should have a good cooling effect. In the radiator modelling aspect, the white matches the orange appearance also relatively fresh. Heatsink installation is supported by the full range of AMD and the Intel lga775/1156 platform.
