Computer Memory FAQ

1, not normal boot

Weapon: Encounter this kind of phenomenon mainly has three ways to solve: first, replace the memory location, this is the simplest and most commonly used one method, generally is the low speed of the old memory in the front position. Second, in the basic can boot on the premise, into the BIOS settings, the memory-related settings according to the low Speed memory specifications set. For example: Use one of the memory (if it is [url= "]ddr[/url]333 and DDR400 memory mixed use, preferably using DDR333 memory), the computer boot, into the BIOS settings, the operating frequency of memory and reaction time slow, with the old memory can be stable operation of the standard, You can shut down and insert the second root memory.

2, the computer operation is not stable

Approach: the emergence of such problems is mainly due to memory compatibility, the basic solution is the same as above. First, replace the memory location. Second, in the BIOS to turn off the memory by the SPD automatic configuration option, changed to manual configuration. Third, if the motherboard with I/O voltage regulator, the voltage can be properly adjusted to enhance the stability of the memory.

3. The memory capacity is not correctly identified after the mixed plug

Ideas: The cause of this phenomenon, the first may be the motherboard chipset itself caused by the reasons, some old motherboards only support 256MB memory capacity (i815 series only support 512MB), beyond the parts are not recognized and used. There are also cases where the motherboard cannot support high memory particles, and the only way to solve such problems is to replace the motherboard or memory. In some cases, you can also resolve this problem by adjusting the insertion order of the memory.

The problem of memory mixed-insert instability is an old problem. In the face of this situation, the author recommends that you choose the memory, such as Kingston, Jin Tai grams of these high-quality memory, because of their electrical compatibility and stability are relatively good, the probability of problems are lower, and after the sale are also guaranteed.

The other part is because of the memory in the use of the process, the gold finger and the motherboard slot contact caused by bad or the virus and other causes of the problem, the specific memory problems and the following ideas. In

4, the computer can not start normally, turn on the computer host power supply chassis alarm horn after a long period of short sound, or open the host power after the computer may start but not normal access to the operating system, the screen appears "error:unable to ControlA20 Line" error message and panic.

Weapon: The above failure is mostly due to poor contact between the memory and the motherboard. The solution is to unplug the memory after opening the chassis, using alcohol and clean paper towels to wipe the memory of the gold fingers and memory slots, and check the memory slot for signs of damage, wipe the test after the end of the memory reinsert, the general problem can be resolved, if still unable to power on the memory unplugged into another memory slot test , if the problem persists, the memory is corrupted and only new memory strips can be replaced at this time.

5, after the boot display the following information: "On BOARD parlty ERROR."

Weapon: the appearance of such phenomena may be three, first, the CMOS parity is set to be effective, and the memory strip on the no parity than the test bit. Second, the parity on the motherboard is more faulty than the test circuit. Third, the memory stripe is damaged, or bad contact. Processing method, first check the CMOS in the relevant items, and then plug in the memory to try, if the fault still can not disappear, it is the motherboard on the odd-even circuit failure, change the motherboard.

6, Windows system running in the DOS state of the application software (such as operating under DOS game software, etc.) when the black screen, Huati, frozen phenomenon.

Approach: This failure is generally due to the allocation between the software, occupy memory conflicts caused by the general performance of black screen, Huati, panic, the best solution is to exit the Windows operating system, in pure DOS state run these programs.

7, Windows operating speed significantly slower, the system has a lot of memory errors prompted.

Weapon: This type of failure is typically due to an application running under Windows illegally accessing memory, there are too many unnecessary plug-ins in memory, applications, active windows open too much, application-related configuration file unreasonable and other reasons can slow down the system, more serious or even panic. The solution to this problem must be to clear some illegal plug-ins (such as 3721), memory-resident program, reduce the active window and adjust the configuration file (INI), etc., if the running of a program when the speed significantly slowed down, then you can reload the application method to solve, If the system slows down when you run any application or program, the best way to do this is to reinstall the operating system.

8, memory is infected with virus program resident memory, the size of the memory value of the CMOS parameter is modified by the virus, resulting in memory value and memory bar actual memory size, in the use of slow speed, system panic and so on.

The first use of the latest anti-virus software to the system for a comprehensive anti-virus treatment, thoroughly clean up the system in the virus. Because of the virus infection in the CMOS, it is possible to restore the default value by discharging the CMOS. The method is to first the CMOS short connection discharge, reboot the machine, enter the CMOS after careful examination of the hardware parameters, correctly set the value of the memory parameters.

9, the computer upgrades for memory expansion, selected with the motherboard is incompatible with the memory bar.

Ideas: Before upgrading the computer's memory bar must carefully check the motherboard main use instructions, if the motherboard does not support more than 512M of large capacity memory, even if the upgrade can not be used normally. If the motherboard supports a problem that is caused by poor compatibility of the motherboard, you can upgrade the BIOS of the motherboard to see if compatibility issues can be resolved.
