775 heatsink

On the computer represents the power consumption of each component, especially the computer's CPU (central processing Unit) GPU (graphics processor) is an important indicator of computer consumption. is the highest power value that CPU companies refer to the heatsink design for a series of processors. TDP technology is to reduce CPU power consumption of energy-saving technology. CPU Power consumption The CPU's TDP power consumption is not the real p

multiplied by the current power under 2 W, can not add the radiator, if it is greater than 2W less than 15W need to add 200x200x4mm3 heatsink Board Adjustable chip output voltage adjustable range in the 1.25v-13.8v package form has the following several: So, the only thing that can add a heatsink is TO-220. Because there is overheating inside the chip protection, so in other packages, if the power consump

Through the fault surface, after a lot of analysis, finally determined that the CPU is poor heat dissipation, resulting in the CPU overheating protection function open and frequent restart. The author's computer configuration is the Intel Pentium 4 630 processor, 1GB ddr2-667 memory, gigabyte 945P-G motherboard, 160GB SATA hard drive, Rainbow 6600GT graphics card, configuration can be said to be the mainstream.

, the current motherboard market is very complicated. It is not easy for us to select a suitable motherboard from the market. Here I will briefly discuss my experience. For intel, the main board interface is relatively simple, and the current market is only 32-bit478And 775 in the 64-bit era. Among them, the 478 interface includes models such as 845,848,865,868, including all the sanyang D series 32-bit processors and many R series Processors. On the
