2. It's legal for now. The object of virtual currency legal relationship is a small amount of funds transfer. This is not only our country, but also the blank part of the world's law. Encountering such economic disputes, we can only use laws similar to gambling law. At present, there are reports that the central bank may enter this field, which may lead to the improvement of the law.
3. The number of cores is not directly related to power
with the same CPU, the power can be doubled in chicken blood mode
CPUs with different process levels can achieve the same performance, and the power can be several times lower
moreover, the nominal power does not represent the actual power in use, so we can search relevant evaluation for comparison
hope to adopt it!!!

The reasons are as follows:
-
power (consumption) = voltage * current
-
when the frequency is over, the voltage will be increased appropriately, and the power consumption will increase when the current is constant
< / OL > -
the overclocking of computer is to increase the working frequency of CPU, graphics card, memory and other hardware through the overclocking mode of computer operator, so that they can work stably at a higher frequency than their rated state, so as to improve the working speed of computer
-
the English name of overfrequency is "over clock", which is a technical means to improve the chip's main frequency by adjusting the hardware settings to obtain the performance beyond the rated frequency
taking the AMD Yilong II x4955 black box CPU as an example, its rated working frequency is 3.2ghz (Hz). As a native four core processor, it can stably exceed the 4GHz air cooling limit frequency only through software. The system can operate stably and complete a successful overclocking
introce overclocking
5. The power consumption and calorific value of CPU will increase greatly after overclocking, exceeding the power consumption of default frequency. Therefore, CPU overclocking has higher requirements for motherboard power supply mole, power supply and CPU radiator.
6. The effect is not very good. The formula estimation you mentioned is frequency doubling, external frequency and dominant frequency. Frequency doubling x external frequency = dominant frequency. Mine is amd 651, 3.0GHz dominant frequency, which is 30 times x100mhz external frequency
7. If the overclocking range is very small, there is no need to increase the voltage, but if the overclocking range is relatively large, the voltage also needs to follow up to ensure the stable operation of the CPU, but in fact, overclocking costs a lot, but the performance improvement is very small, so it is recommended to upgrade the CPU directly.
my notebook is the 5870 card, which is actually the same thing as your 5770, I've tried overclocking CPU and overclocking GPU. In fact, it has been proved that the calorific value is greatly increased, but the performance improvement is not obvious

8. Note for CPU overclocking
1. Intel platform
since all Intel CPUs are locked for frequency doubling, we can only increase the external frequency for overclocking. However, don't be impatient when overclocking the Intel processor. It's better to increase the external frequency by 5MHz. If the FSB is increased to a certain range, the system is not stable, you can increase the voltage slightly. After all, for Intel's CPU, the effect of adding a little voltage is obvious. Here to mention is the motherboard to support the change of voltage, otherwise overclocking margin will not be too large
If a transfer card is needed, it is better to select or replace a transfer card with adjustable voltage. First of all, it is very dangerous to pressurize Pentium4, which is the core of Prescott. Many websites have reported that pressurizing will cause Prescott to burn down. After refreshing the BIOS supporting Prescott CPU, the MSI motherboard even blocked the option of adjusting the CPU voltage. It can be seen that pressurizing will burn down Prescott, which is not an empty story. Therefore, I recommend that when overclocking the CPU of Prescott core, try not to pressurize it. If you have to pressurize it, then the amplitude should not exceed 0.1V
in addition, since the external frequency is increased, it will have a great impact on other components. Therefore, it is recommended that AGP and PCI frequencies be fixed at 66 / 33 MHz as far as possible. For motherboards without AGP / PCI fixed frequency settings, it is best to use 6-frequency division. If it fails, try 5-frequency division again. For DDR frequency division, the setting of DDR and external frequency synchronization (1:1) is preferred. In case of failure, consider other DDR frequency division settings such as 4:5. Of course, if your memory is above ddr500 level, then choosing DDR and external frequency synchronization is the best choice. Of course, the high-frequency Pentium4, especially the heat of Prescott core processor, can't be ignored. Therefore, you'd better choose an excellent heat sink and use the temperature monitoring function of BIOS for safety<
amd platform
the stability of a stable power supply directly determines the height of the overclocking frequency. Only when the voltage and current are stable, can the CPU give full play to its overclocking potential
2. When purchasing radiators, we should pay attention to buying famous brands such as cm, TT and AVC as far as possible, and their 100 yuan procts should be able to complete the task well
3. When there is no good memory, in order to achieve the success of overclocking, you can choose the operation mode of external frequency and memory operation frequency of the motherboard to run asynchronously, so that the memory subsystem of your system can maintain stable data processing performance at high frequency. But remind you, or try to let the external frequency and memory frequency consistent, so that you can get the most powerful performance
4. Improve the heat dissipation of Beiqiao. The performance of Beiqiao is very important for your CPU to get higher external frequency, so you can try to build a more powerful heat dissipation system for Beiqiao
summary
it's obvious that we can reach 2G or more frequency on the Sempron 2400 +, which is the lowest end of the market. In fact, this achievement is expected. The 2800 + can reach 2.5G, which I think is quite good. Due to the high efficiency of execution, we have seen the performance of Athlon XP with 2.5G dominant frequency before. Sempron with 754 interface is the real form of flash dragon in the future. It has strong performance, and can be upgraded to Athlon XP 64 in the future without replacing the motherboard. Of course, I hope there will be a way to turn on the 64 bit computing function that has been turned off in the future. I believe that this is not a fable. In the period of dragon sheep war, what is impossible
the key problem of overclocking lies in two aspects: one is CPU, the other is memory. Since the CPU of K8 comes with its own memory controller, the clock of DDR comes from the CPU. So in case of overclocking, although your DDR400 memory is DDR400 when it is displayed, your DDR clock will be improved correspondingly because you overtook the external frequency of CPU, so it is no longer DDR400 at this time, but higher than DDR400. How much CPU can be used_ Z's software
so in this sense, the higher your CPU is, the lower your DDR will be, depending on your memory. For example, if you are a DDR400 memory, you should ensure that your memory frequency is close to DDR400, but not too high, otherwise you will not be able to exceed it. In fact, is there a way to improve the clock of CPU and lock the memory in DDR400 (clock 200m). For the K8 CPU, this can't be done, because the K8 CPU has only one set of clocks. DDR clocks are separated from the internal PLL circuit. There is a ratio between them, which has been set since the CPU was designed. Therefore, when the CPU is overclocking, it is also based on this ratio, which is called water rising ship height
you can use Intel's algorithm for reference and roughly estimate the memory frequency of your overclocking. 200 / 400 = FSB / x, FSB is your super CPU frequency, X is your current memory frequency. If you set the memory of DDR400 as auoto, that is DDR400. If you exceed 250, your DDR actually runs in ddr500. This is a general algorithm, and there will be errors in practice. It is recommended to use CPU-Z to see the CPU and memory frequency
of other hardware
first of all, you must prepare a fan with excellent quality for your CPU, and it is best to meet your CPU certification
2. Just when you are ready to install the fan, remember!! The die on the processor must be coated with cooling paste; Don't be too thick~& gt;， There is also a small layer of heat sink in contact with die~~ PS: I personally think the cooling paste is better!! Because most of the test results of "heat release adhesive" on many websites are "heat resistance"
3. Please adjust to the original frequency after installing the fan!! PS: avoid setting error, overheat and burn
4. After completing all the installation actions!! Please do not cover the chassis first!!! Because to observe whether the fan is rotating
5. Important!!!!!! Please form good habits!!! Just press "del" to open the BIOS to see the temperature of the CPU as soon as the machine is turned on!!!! If the temperature keeps rising!!! Please turn it off immediately
6. Watch the temperature displayed by the temperature monitoring software frequently
7. If you have a fan protection in the BIOS of your motherboard, please turn it on as much as possible for people who use air cooling!!! For example: kt7 ~ ~
8. Don't save money to buy a good power supply! must! You can't listen to anything else. You must listen to me
9. If you have the conditions to choose a better memory, hard disk and graphics card, your overclocking space will be increased
but there are exceptions. This article is not necessarily comprehensive! Just hope to minimize the chance of burning! The core of overclocking is to achieve an ideal balance between voltage, clock frequency and heat dissipation< br /></ TABLE>

9. As the frequency increases, the voltage will naturally increase and the power will also increase. It mainly depends on how you exceed the frequency, whether it is soft or by adding voltage. Generally, the increase of the frequency is not a little bit, which can be ignored
10. The power can not be increased at will. You must understand the electronic principle to refit the circuit diagram. To increase the power, you must replace the power amplifier tube and circuit structure. If you don't understand the principle, you can't increase the power. Adding a capacitor will not amplify the power. The capacitor can only filter, decouple, store energy and bypass, so it has nothing to do with the power.
