Capacitor is the most common electrical component on the motherboard. It mainly plays a filtering role to ensure the stability of voltage and current.
Capacitors are divided into solid capacitors and liquid capacitors. The advantages of using solid capacitors
are that they will not explode. In addition, solid capacitors operate at high frequencies
It presents a lower impedance, so it can still work stably even under overclocking conditions. Solid capacitors can withstand high ripple current. Solid capacitors have an ultra-long life. Different temperature
The service life is 60% to 300% longer than that of liquid capacitors.
Finally, it has high temperature resistance.
So when buying a motherboard, you should choose one with more solid capacitors, but that doesn’t mean
Solid capacitors are necessarily better than liquid capacitors. It cannot be determined from the electrolyte form alone
Comparison.
The main function of an inductor coil is to filter high-frequency signals. We often see the following three forms of inductors on the market: open, semi-enclosed, and fully enclosed.
Open inductor---thin wire diameter, more windings;
Semi-closed inductor---thick wire diameter, few windings;
Now As long as the motherboard is not a brand-name one, you generally don’t have to worry about this.
Just try to choose solid capacitors.

The more layers the PCB has, the better. Generally, 4 layers are enough for users, there is no need to use them
6-layer design. If dual CPUs are installed, a 6-layer design is required. Generally,
the top and bottom two layers are the "signal layer", and the middle two layers
They are the "ground layer" and the "power layer". Placing the signal
layer on both sides of the power layer and the ground layer can not only prevent phase
interference with each other, but also facilitate the correction of the signal line.
******************************************
The disadvantages of the large number of CPU power supply phases---the design cost and material cost
are increased. Generally, 6-phase power supply is enough, and more is just decoration.

A disk array is a system that combines several hard disk drives into a whole according to certain requirements, and the entire disk array is managed by an array controller. .

It is very easy to judge whether it is a new machine. You can refer to the following points
:
1. Look at the serial number. If it is a notebook, please check the body. Whether the battery and outer packaging serial numbers are consistent, generally they should be the same;
2. Look at the screws of the machine;
3. Look at the cooling fan. If there is a layer of dust on it, it is basically the same. It is used;
4. Look at the production date;
5. Look at the power-on time of the hard disk;
There are many methods and require comprehensive analysis.

How to identify the authenticity of Kingston memory:
1. The solder joints on the genuine Kingston memory circuit board have an anti-oxidation gold plating layer, while the fake ones do not have a gold plating layer to save costs.
2. The 30-digit serial number on the Kingston label can be verified on the website.
3. There is a serial number on the side of the circuit board, and the 4-7 digits are consistent with the 30-digit serial number on the label.
4. The letter R in the upper right corner of the Kingston trademark on the Kingston label is surrounded by the words Kingston, not a circle.
5. The Kingston distributor’s label can be verified after being uncovered.
6. The numbers of the memory particles on each memory stick will not be exactly the same, so please identify them carefully.
In terms of compatibility, generally big brands will have no problems
It mainly depends on what model and brand your motherboard is
FSB /How much is HT? Whether it is supported, etc.
The specifics need to be tested before we can tell.
