formula z motherboard

How much is the motherboard temperature normal? With the continuous development of science and technology, the current motherboard can withstand the temperature can reach 110 degrees, but the motherboard for a long time in the high-temperature state of work, will make the motherboard, chipset life reduced. Therefore,

Proof: Using formula (n-1) 3 = N3-3N2 +3n-1 S3 = +23 +33 +43 +...+n3 S2 = +22 +32 +42 +...+n2 S1 = 1 +2 +3 +4+...+n = S3-3s2+3s1-n = (1-1) 3 + (2-1) (3-1) 3 + (4-1) 3 + ... + (n-1) 3 = S3-n3 = 3S2 = 3s1+n3-n and s1= N (n+1)/2, = S2 = N (n+1) (2n+1)/6 i.e.: +22 +32 +42 +...+n2 = N (n+1) (2n+1)/6 similarly push Related: (a+b) ^n=a^n+c (n,1) a^ (n-1) b+c (n,2) a^ (n-2) b^2+c (n,3) a^ (n-3) b^3+......+c (n,n-2) a^2b^ (n-2) +c (n,n-1) ab^ (n-1) +b^n Ya

LightOJ-1045 Digits of factorial Time Limit: 2000MS Memory Limit: 32768KB 64bit IO Format: %lld %llu Submit StatusDescriptionFactorial of an integer was defined by the following functionF (0) = 1f (n) = f (n-1) * N, if (n > 0)So, factorial of 5 is 120. But in different bases, the factorial is different. For example, factorial of 5 in base 8 is 170.In this problem, you have to find the number of digit (s) of the of the factorial of

Motherboard detection card 1. Tool Introduction The motherboard diagnostic card converts the detection process of the BIOS internal self-check program into code when the motherboard is started. It reads the code displayed on the card and compares it with the fault code table, you can quickly diagnose or locate faults in the main board, memory, CPU, power supply,

Computer Motherboard Repair Method One, CMOS parameter loss After the boot prompts "CMOS Battery State Low", sometimes can be started, using a period of time after the crash, this phenomenon is mostly caused by CMOS power supply. For different CMOS power supply methods, take different measures: 1. Welding Battery: Soldering a new battery with soldering iron. 2. Button-Type battery: direct replacement. 3. Chip Type: Replace this chip preferably wi

How to solve the problem of computer motherboard crash Motherboard is the key part of the computer, once the failure will make the performance of the machine is affected, or even normal use.

The motherboard leakage Solution method: In general, the motherboard is now a bad power supply heart slice is very likely, the power supply heart piece is broken, the CPU generally no temperature, at this time you can use digital multimeter diode gear measuring inductance and ground, if the multimeter is called a long word, power supply heart is good, if the inductor to the ground short-circuit, the

Motherboard Temperature detection method: First we download and install the Aida64 software. After downloading the aida64, unzip, run and install, after installation, we open the AIDA64 to see the main interface Then we click on the left side of the computer, sensors, the picture of the motherboard temperature is the motherboard temperature.

Although assembling a computer is not difficult, but DIY hardware collocation is still a lot of novice friends more headaches. For example, CPU with what motherboard issues, how to match the compatibility and cost-effective solutions. Some netizens think to check CPU interface and motherboard slot is very troublesome, and the cost-performance aspect also is not good to handle. Today's small series to bring
