" still advocate the use of rotating disks (mechanical disks). Frankly speaking, when it comes to manipulating databases, these arguments are often outdated or completely wrong. Today, SSDs offer considerable performance and reliability at a high price. However, not all SSDs are applicable. For a database server, you should use an SSD designed for server workloads that will protect data (for example, during a power outage). Avoid the use of commercial SSDs designed for desktop and notebook co

the graphics card, so that the majority of users can spend a smooth and refreshing summer. In the near future you want to install or replace the graphics card users must not miss. Large size three fan heatsink shadow Gtx960gamer Recommended reasons: The GTX960 Gamer graphics card hits a large size three fan heatsink, providing more robust air volume, even though the graphics card can still keep the temp
Buy the motherboard to save the computer, as long as the chipset, can be used, then why do people have to choose a more luxurious, more functional high-end motherboards? Many friends have had such a question. For this question, the little lion can only say, has not experienced, may really not understand "tyrants" why has this demand, in fact all reason, all lies in the experience difference. Small Lion today take gigabyte Z170X-UD3 Ultra This luxurious version of the Z170 motherboard for example
courage to use it. As a result, today's notebook fans are all using noise reduction design. 1, intelligent control speed + seismic noise reduction Many users will find that when playing the game, The notebook fan will emit "whistling" sound, and in the system desktop does not run the program will be very quiet. In fact, this is the Intelligent fan control system, at low temperature, the slow rotating fan makes the noise greatly reduced, only when the CPU, graphics and other components of the
As the heart of the computer, the calorific value of the CPU is quite alarming. General CPU through thermal conductivity silicone grease will heat into the radiator, so as to achieve the purpose of cooling. CPU heat is too high, the system will occur blue screen, panic, restart and so on, so the thermal conductivity of the CPU becomes particularly important. So how do we go about using thermal grease?It is best to apply thermal grease between the heatsink
the Reset function key on the right to restore QVM2100 to factory status. To say here about the heat dissipation problem, QVM2100 is a high-performance product, but it does not have a built-in cooling fan, it is the practice is to extend the heatsink and the top of the iron shell, so that the heat on the heatsink is transmitted to the fuselage, in the actual use of the top warm, but at this point to pay at
, pressure on the CPU of a cast aluminum plate, which has a curved compressed copper tube, glued embedded in the aluminum plate groove, one end on the CPU, the other end extends to the most outer end of the heat sink. According to the author's testing and use, found that the design of the factory to improve the effect of heat dissipation is very small, because when the heat accumulation to a certain extent, the heat pipe and aluminum plate temperature is the same, can not form a large temperatur
" fault, we may wish to try. Tip Two: When the installed hardware is not recognized by the operating system, set the "PNP OS installed" (Plug and Play) project for the CMOS settings to Yes or NO, try. 5, the main board North Bridge chip cooling effect of some motherboards will be the North Bridge chip Heatsink omitted, which may cause the chip cooling effect of the system to run for a period of time after the crash. In this case, you can make homema
Many friends will install an efficient radiator in the mainframe to ensure a long period of stable operation, high-end gamers and game enthusiasts pay particular attention to heat. As an important part of the chassis operating environment, the heatsink does require the player's heart. However, not all users are familiar with the way the hardware is used, some DIY novice to the radiator selection and use of a certain misunderstanding, but also vulnera
, with its bulk products, is simply "seamless." There is no doubt that if the manufacturers do not take some necessary measures, then the average consumer is almost powerless. The routing of boxed products, whether Intel or AMD's CPUs, is a matter of great concern. In the case of Intel CPUs, a large portion of the boxed products on the market are counterfeit. The so-called fake boxed is nothing more than two cases: the bulk CPU and the original heatsink
When cleaning the motherboard and CPU, on the heatsink and chip surface of silicone smear, but after applying silicone, the temperature did not fall, but rose higher. If the silicone smear too much, not only will affect the heat conduction, silica gel also adsorbed some dust, after mixing will seriously affect the cooling effect. and silicone touch too much, in the chip and heatsink between the extrusion,
reason? Answer: When playing the game, the reason for the dead flower screen is more, one is the graphics card's own hardware problems, such as the display of the graphics card is a minor damage, graphics card workmanship or poor compatibility, will lead to the electrical performance of the video card greatly discounted, such as this situation is best to use the replacement Because of the use of AGP8X graphics card, users can also in the BIOS to adjust the speed of the graphics card to agp4x t
not exceed 3.5mA. Temperature requirements refers to the chassis power supply internal temperature should not exceed 65 ℃. Electronic interference is divided into two kinds of conduction interference and radiation interference, conduction interference through the power line transmission, the frequency of 30 MHz below, the main interference audio audio section, such as the start of the power in the vicinity of the TV, audio and other household appliances may not be normal use, this is the impact
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
maintenance and maintenance, this time to come in handy. 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.

But after running for just
