How to maintain the CPU

　　1. How to maintain CPU

Q: How do I maintain the CPU?

Answer: First of all to ensure good heat dissipation. The normal operating temperature of the CPU is below 50 ℃, the specific operating temperature depends on the frequency of different CPUs. Heatsink quality should be good enough, and with the speed of the function, so with the motherboard monitoring function with monitoring fan work, the bottom of the heatsink to thick for the best, this is conducive to active cooling, to protect the internal and external air flow smoothly. The second is to decompress and shock. CPU "died" in the heat and buckle the tragedy of the pressure is heard, the main performance in the CPU dle is crushed, so the CPU should be aware of the force should be even. The pressure on the buckle should also be moderate.

Overclocking should be reasonable. Now the mainstream CPU frequency is above Lghz, at this time the significance of overclocking has been little, more consideration should be extended the life of the CPU, such as the need for overclocking. Can consider Qian voltage overclocking.

Finally, use silicone grease. Silicone grease in use to apply to the CPU surface of the core, a thin layer can be, excessive may leak to the CPU surface interface. Silicone grease in the use of a period of time will be dry, at this time can be removed from the net and then be coated with silicone grease. Improved silicone grease should be more careful, because the modified silicone grease is usually added carbon powder and metal powder, then the silicone grease has a strong conductivity, when the computer is running when the leakage to the CPU surface capacitance on the consequences of not thinking.

　　What are the requirements for the power supply and chassis 2.P4

Q: I recently wanted to work with a P4 computer, what is the so-called P4 special case (power) is what is going on? Does P4 really need a dedicated power supply?

A: You know the power supply is the source of the power of the whole computer. If there is any malfunction in the power supply, any parts of the computer may be destroyed. If the power supply quality is unreliable, the system will run extremely unstable. With the computer CPU, memory, card chip clock frequency increase, the speed of the CD-ROM drive faster, the increase of cooling fan, so the power supply performance requirements are greatly increased. Especially after the introduction of P4, as the current power of the largest desktop CPU processing chips, its power can be up to 60w or more, if the power supply performance is likely to be inadequate. Therefore, on the chassis and power requirements. The P4 has new requirements. We must pay attention to the chassis and the power supply when assembling the P4 computer.

　3. Choose a good radiator for Athlon XP

Q: The CPU I use is thomughbred Athlon XP, what kind of radiator should I choose?

A: AMD CPU heat is more famous, and when Athlon XP using 0.13 micron process, Thoroughbred core Ath1on XP power and core voltage have been reduced, but the new ATHLONXP calorific value is still relatively large, Plus die's surface area is much smaller than Palomino ath1on XP, so we have to choose a better CPU heatsink for the new Athlon XP.

If we use the new Athlon XP, those cheap radiator best not to use, because this kind of radiator and "PU core contact part of the material, most of the use of aluminum alloy, therefore can not meet the requirements of CPU heat dissipation." According to AMD regulations, due to the radiator caused by the burning of the CPU is not warranty. Therefore, it is recommended that consumers in the use of new Athlon XP, the choice of those after the AMD-certified radiator, and the best to buy those who have good reputation brand fan.

　　4. Double CPU does not equal double performance

Q: I would like to buy a dual CPU, I heard that this can achieve double performance. Is that the case?

A: Dual CPUs require operating system and application support to be effective, to achieve the dual-CPU performance, you must meet the following two conditions: ① installation and use of a special multiprocessor operating system. Windows98 is not supported for multiprocessor. If the operating system you are using is Windows 98, the dual CPU does not work with any program. To perform dual-CPU performance, you must use a multiprocessor-enabled operating system such as Windows2000, Windows NT, Linux, etc. (recommended for use with Windows2000). ② multi-threaded programs that support multiprocessor, the most common currently only Photoshop, 3DStudio Max and several. In addition, even if the above conditions are met, can only be based on the corresponding operation of the software to obtain 1.2~1.8-times performance, there can be no double performance.

　　5.cm0s Display CPU frequency is not correct

Q: After my computer post, the system shows CPU working in 450MHz, but in the BIOS setup interface, the "CPU INTERNAL CORE SPEED" in "Bios&cpu Featuressetup" is 350MHz. I don't know what the reason is?

A: Some motherboard bi0s found that the hardware will automatically reduce the CMOS parameters to the safest setting after the system has been updated. The bi0s program, which supports CPU working state settings, automatically drops the CPU operating frequency to the lowest frequency CPU supported by the motherboard. Your system FSB to 100MHz, and 100MHz FSB CPU minimum frequency is 350MHz so the BIOS setup interface should show 350MHz (3.5xlOOMHz) is a normal phenomenon. Why does the system show that the CPU is working on the 450MHz (4.5x100mhz) Since your CPU is locked in 4.5, which is also a normal phenomenon.

　6. Correct treatment of the motherboard detected CPU temperature

Q: My computer turned on, bi0s on the display CPU temperature of 48 ℃ (room temperature 25 ℃ or so), do not run any program in a few minutes after the temperature will rise to 54 ℃. What's the problem? Does it have any effect on the hardware in the long run? What value should I set the CPU alert temperature on the motherboard?

A: The motherboard to detect CPU temperature is based on the CPU base of the probe to complete the head. Probe warm head to do a bit higher, from the CPU near. The detected temperature is high, and the head of the temperature probe is lower. Far from the CPU, the detected temperature is low. The height of the temperature display does not affect the hardware work.

Setting the CPU alert temperature in the BIOS is based primarily on the limit temperature that the CPU can withstand. The general warning temperature is set to 20 ℃ less than the limit temperature it can withstand.
