Troubleshooting of CPU Hard overclocking failure

Do not condone a friend in the purchase of the machine will choose that extraordinary can "super" processor, and then with a piece of work, the use of good motherboard, through overclocking, that is, can be very good to save money on hand, but also to get higher performance, why not? In fact, the CPU for overclocking is no longer what new, basically save machine friends will be the first choice to consider the purchase of a special super processor. We did get a lot of performance improvement after overclocking the CPU, but we didn't just have to choose the right motherboard, memory and CPU, and other accessories were important. This is not, pen pal friend The newly assembled computer ran into trouble.

Failure performance: Last year AMD launched the 64-bit speed Dragon This processor believes that most netizens are not unfamiliar with it! The processor has been courted by many players due to its excellent overclocking performance. Now with the price of lower, less than 600 yuan price really let a lot of users envious. This is not, a friend of the writer recently assembled a configuration that uses the AMD Fast Dragon 3000+ processor. The specific configuration is as follows: 64 AMD Fast Dragon 3000+ processor, Kingston 512MX2 DDR400 memory, gigabyte NF4 chipset motherboard, Seagate Cool fish Nine generation 160GB SATA hard drive, Rainbow 7600GT graphics card. Look at this configuration, the 64-bit speed dragon 3000+ to 2.2GHz should not be a problem (AMD Speed Dragon 3000+ The actual frequency of 1.8GHz). But the friend only will the processor ultra to 1.96GHz on the question unceasingly, either freezes or restarts, simply cannot use normally. Let alone 2.2GHz, what is going on here?

Failure analysis and resolution: Open a friend's computer, into the BIOS settings, the first FSB to 200MHz, frequency multiplier restore to 9X (without overclocking the default settings), save the computer restart after the exit, can smoothly carry out the system, and run for more than half an hour after the game, still no problem, see the default does not overclocking, The system is no problem.

Restart the computer, press the DEL key to enter the motherboard BIOS settings, the FSB from 200MHz to 210MHz, restart the computer, the results are relatively normal, the machine can be normal system and can normally run most of the applications, at this time the CPU frequency is 1.89GHz. Reboot first, enter the BIOS and set the multiplier to 220MHz. At this time the CPU frequency is 1.98GHz, reboot, although the machine can enter the system normally, but in the use of very unstable, less than half of the time, there have been two times restart, what is going on in the end?

The problem is that the CPU's physical problems (although for the same model of the CPU processor, but due to the factory time different in the overclocking performance is also not the same), should not ah, the physique should be too bad to 2.0GHz bar. Fortunately, the author is also the application of the same model of the machine, configuration in addition to the graphics card, the other basically the same. So the author will remove this CPU, loaded into the author's machine, and the boot into the BIOS settings, directly set the FSB to 250MHz, reboot, the machine smoothly into the system, played two hours of the game, and ran 3DMARK, all normal, fairly stable, So what the hell is going on here?

Go back to your friends and find out why, the first thing to suspect is memory. But two Kingston DDR400 512x2 memory should be no problem, in order to verify, the author incidentally brought their own use of gold state DDR400 memory, into the author's machine to test again, the problem remains, the frequency still can not exceed 1.98GHz, it seems that the memory is not a problem!

Motherboard because the author and friends are using Gigabyte NF4 standard version, should not have any problems, so in the end is which part of the problem?

It's not a power problem, is it? Suddenly thought of a friend in order to save costs, the use of the chassis with its own power supply. The power supply is nominal 300W! Let's test it. Run the Power test software immediately after the occt,30 minute test, from the test results diagram, I found that the 5V end of the power supply has been heavily loaded, voltage fluctuations up to 5.24V, almost to the 5V end can withstand the maximum (5V reasonable fluctuation range: 4.75v~5.25? V), at the same time the 12V voltage also appeared a certain rise, up to 12.2V. It seems that the power is really not good, load capacity is poor, and OCCT parameters I also set a more conservative, if the CPU occupancy rate to highest the highest, I am afraid even the test is difficult to persist.

Then carefully observe this Taiwan's kitchen power supply, found that the power supply has a serious "shrinkage" phenomenon, its output power of each port is too small: 12v~6a, 5v~13a, 3.3v~5a, -5v~0.5a,- 12v~0.5a, output power of about 130W, God knows this number has no moisture, if there is, it simply can not support the high power consumption of AMD processors, let alone is overclocking! So I will my own Great Wall Dragon 360SE power supply to friends, the CPU FSB immediately stabilize ultra 166MHz, but on 200MHz will have to add 0.05V voltage. But this has made me satisfied, it seems that overclocking failure is really the power in the mischief, such a good CPU almost was "wasted."

Seize the time to buy a brand in the market power of 300W power supply, after the test, the direct FSB to 250MHz, restart after the machine started smoothly, running a variety of games, application software are no problems, so, the problem of the truth.

Fault Summary: This is a common overclocking fault, the current market in the chassis brand is very messy, since the power supply although nominal 300W power, but the actual power of some power even 200W is not, stable operation has become difficult, let alone to overclocking it! Therefore, the power problem can not be ignored Ah, in particular, upgrade the CPU, graphics card friends, upgrade before the best Test your own power can withstand high load, do not be the power to drag the hind legs!
