Memory common fault solution

1. Windows installation error due to poor memory stick Quality
Fault description: A new compatible machine is configured as P4 1.8 AGHz, i845G motherboard, Hynix 256 MB DDR266 memory stick, and Seagate cool fish 5 generation 60 GB hard drive. Windows 98 is installed after the hard disk is partitioned. An error is reported when you copy the system file during the installation process. After you press "cancel", you can skip the error and continue the installation. However, an error is reported again later, windows Installation cannot be completed.
Fault Analysis: Because the fault occurs in the system file copy phase, it is initially suspected that the problem is the installation of the disc, format the hard disk and replace the Windows 98 installation disc for re-installation, the fault remains. The fault points are transferred to the hard disk and memory stick. After the hard disk is replaced, the fault still exists, and the possibility of hard disk failure is eliminated. After the memory stick is replaced, the failure that causes the Windows installation error is confirmed to be inferior memory stick. During Windows 98 installation, files need to be copied from the CD to the hard disk, and the memory plays an extremely important role in this process as a transit station for system data exchange. In this example, the system file copy error occurs because the memory is of poor quality and cannot work stably.
2. Frequent registry errors and memory failure
Fault description: one computer is configured with P Ⅲ 550MHz to 731 MHz), SiS630 motherboard, and Hynix 192MB128MB + 64 MB memory. After more than a year of use, the system becomes unstable, and a registry error often occurs after the system is started into Windows, prompting you to restore the registry.
Fault Analysis: At the beginning, the hard disk was formatted because the operating system was unstable. After the reinstallation, the problem is not completely solved, or even becomes more serious. Sometimes, the "Windows Protection Error" Error is prompted. Since the CPU has been running in the super-frequency state, it is initially suspected that the fault is due to the CPU. After the CPU is downgraded, the registry error frequency is significantly reduced. After the CPU is changed, the fault does not disappear, it still appears from time to time. In order to completely eliminate the fault, the replacement method is used for testing, and the culprit is the 64 MB memory. The computer has been running at a high frequency for a long time. The clock frequencies of CPU and memory are both 133 MHz. The 64 MB memory is used by the HY-7K chip, the work is also poor, long-term 13 3 MHz external frequency running overwhelmed, resulting in frequent registry errors. Some memory disks with poor workmanship and low parameters may work frequently for a period of time. However, problems may occur and system faults may occur over time, which is a concern for users.
3. The computer cannot be started because of the memory stick that has been polished.
Fault description: one computer is configured with a pⅲ 800EB, a via 694X motherboard, and a Hynix 128 MB PC133 memory. After a MB Hynix PC133 memory is added, the screen is black and the computer cannot start up properly. After the memory is unplugged, the fault disappears.
Fault Analysis: After inspection, it is found that the new memory stick is normal and can be used normally on other computers, but it can only work at MHz of external frequency and cannot be used at 133MHz. To use this memory stick, you have to set the asynchronous working mode in the BIOS memory settings. The serial number on the chip of the memory stick is "-75". It should be a PC133 memory stick, but the handwriting on the chip is vague, it is very likely that it comes from the memory Remark (polishing) of-7 K or-7J, and naturally cannot work at the 133MHz external frequency. Therefore, when purchasing a memory stick, consumers should pay attention not to buy a Remark memory stick.
4. Memory Stick incompatibility causes capacity to be incorrectly identified
Fault description: a brand-name machine, configured as: P Ⅲ 800, i815E motherboard, Hynix 128 MB memory, and later added a Hitachi MB memory, but the total memory recognized by the motherboard is only MB.
Fault Analysis: after testing, the two memories on the computer can be used independently, but only 128 MB can be recognized at the same time. We can see that there is a compatibility problem between the two memory, later, the new memory stick was replaced with a memory stick using the Hynix chip, and the fault was solved. Due to the difference in electrical performance, there may be compatibility problems between memory strips, which may be more likely to occur in mixed insertion environments of memory strips of different brands. Therefore, try to select products of the same brand and model when using two or more memory stick, so as to avoid Memory Stick incompatibility to the maximum extent. If you cannot purchase the same products as the original memory stick, try to use the brand stick with good reputation in the market. They are generally subject to strict special matching and compatibility testing, it can also meet or exceed industry standards in terms of components, design and quality. Of course, not all brands of memory stick have good compatibility.
Because the memory stick has a very important position, the use of inferior memory stick may sometimes have unexpected results, so we recommend that you try to buy a high-quality brand memory stick.
