For example: 1

Fault performance: a computer installed two memory, but the boot only shows one.

Failure Analysis: Open the box to check and found two different memory brand, design work are very different.So first we put the memory into a separate machine on the test and shown the memory is 128M, there is no problem, but with the plug still showed 128M, swap the memory slot is useless. Obviously, the memory compatibility problems exposed,so we let him take the old memory to the market in exchange for the same memory that first upgrated,then the trouble has been ruled out.

Maintenance experience: though there are not many memory compatibility issues, but the harm is great, as they often have a lot of strange performance, we still try to avoid a mix of different types of memory, so to avoid compatibility issues.

Fault 2

Fault performance: a computer configured KT133 motherboard, Geforce4 MX440 graphics card, 128M memory, installed Windows XP crash frequently, not always installed.

Failure Analysis: the owner just dusted the computer and then the system crash occurs,then can not be installed on the system. After the hardware look carefully and found that there is a memory rather than hard-obvious scratch, injured part of the circuit on the PCB, it appears that the problem is here. After exchanged another memory, fault disappears, it seems that the original memory has been completely damaged. 

Maintenance experience:

When install your computer or clear the dust, it must be careful not to damage the hardware, accidentally damaged parts will be completely avoidable

Fault 3

Fault performance: a normal computer: 815EP motherboard, 128MB memory , when get a 64MB memory, with the plug after, the total memory only identified 64MB.

Analysis of solution: the first memory installed into a single motherboard to confirm, they are good,we can rule out the memory of the quality problems, it appears that the compatibility issue again. However, this method used for memory is not very realistic, after all, the white point smaller 64M memory, 128M of memory for a lot of spending need. Suddenly recalled that the motherboard BIOS upgrade may have improved memory support,

Maintenance experience: a lot of compatibility issues when upgrading the motherboard BIOS can be resolved,and drivers download is not to be forgotten.

Fault 4

Fault performance: a computer configured to Celeron 667MHz, BX chipset motherboard, Hyundai 128M SDRAM, boot black screen suddenly one day, buzzer alarm.

Failure Analysis: warning issued by the voice of the main board can determine, it is highly possible that the memory or the memory slot problem. Pull down the first memory, and install to another slot, fault remains, it appears that the normal memory slot; and then plug in the memory for another, failure disappeared. Memory appears to be a problem, but the possibility of damage memory is very small, so look carefully memory, found some golden finger thick dirt, it seems that the problem is contact.rubber was used to clear goldfinger several times, re-insert the slot and found that all normal.

Maintenance experience: Goldfinger and memory slot access is good or not, for the stability of the work is very important. If a similar bad, we can only use rubber clean it,it is very simple, So you need to clean up your computer to prevent dust damage.

Fault 5

Performance: originally intended to expand the memory, the results of capacity rather than smaller.

Failure Analysis:my friends get four models of the same capacity memory, and installed all memory.but capacity are smaller than before, checked manual, the total capacity of memory does not exceed the maximum amount of motherboard  memory,it appears to the motherboard BANK support,when tested on three memory show normal, once spent four total capacity will appears as a memory capacity, so we can only removed a memory. Approach to replace the memory will not work.

Maintenance experience: BANK supported by the motherboard is not the number of the motherboard has four memory slots can support four, it is also necessary to look at the number of memory BANK number with the motherboard supports. in addition to support dual-channel memory,you can use two memory,but we suggest that you use a single large-capacity memory better.
