Battery Review and Tips

Start the system or run the application, the system reported: “error: unable to control A20 line”, “memory write / read failure” or the newspaper: “memory allocation error” and so on, these issues are considered failures of memory error, it reduced the memory out of memory and parity errors are different.

System News “memory error” there are three cases were caused by different reasons. First POST Times “memory error” caused the failure was mainly due to memory or memory controller, OLYMPUS li-42b battery hardware failure; the second is set in CMOS when boot the system is not self-1M or more memory, and running applications program, the system reported “memory error” caused the failure may be due to memory or memory controller, hardware failure, it may be a software failure; Third, by POST to enter DOS or Windows, run the application in reported “memory error” caused the failure was mainly due to software failure.

For the memory failure caused by software errors, and handled according to the following steps to check:

1. If you are running applications under DOS Times “memory error”, the doubt whether a memory allocation error, check the applications running on DOS and whether the conflict and make the appropriate treatment. Generally by restarting the system or re-writing system configuration files to solve the problem of the application can be resolved through the appropriate changes.

2. If you are running applications under Windows environments Times “memory error”, the doubt whether by the application caused the illegal access memory, general CANON NB-5L Battery memory-resident programs can be removed to reduce the active window, adjust the configuration program or reinstall system and application procedures.

3. If the problem only in a particular application is running only appeared, probably caused by the software.

4. Using KILL or KV300 + detection system for viruses, there are anti-virus.

Memory errors caused by hardware failure is more common, CMOS settings wrong, bad memory, combination memory installation error, damaged hardware, memory, the memory controller error Dengjun will be a memory error, the general inspection and treatment according to the following steps:

1. POST is displayed as “memory error”, first enter the CMOS settings, check the CMOS memory on the parameters are set correctly, and whether the configuration of memory in line; for example, if you set read and write cycles of memory or memory memory read and write wait time is less than the actual value, it should increase the memory or increase memory read cycle to read and write latency.

2. If the problem persists, check the memory and the NIKON EN-EL10 Battery memory is good contact between the outlet slot and make the appropriate treatment.

3. If the error persists, check the combination of memory installed is correct. General installation of the motherboard memory sockets are divided into several bodies (Bank), each body has two to four sockets to install memory, memory that can be installed two to four articles. Since the first 72 lines of memory can provide 32-bit valid data (30 lines memory has been eliminated and will not be discussed here), for Pentium class CPU, the data line 64, to one able to access 64-bit data, must install two 72 line memory, so the 586 PC’s motherboard, the general must be an even number of memory installed 72 lines, that one should be installed 2 or 4 of Article 72 lines SIMM memory. If the memory socket on the motherboard is 168 lines, 168 lines of memory as a 64-bit can provide valid data, so only one can be installed properly. Install memory should note the following:

For most PC machines, the Bank is not in the same capacity within the mixed interpolation of different articles with SIMM. Many PC-SIMM can be installed in a different capacity, but packed in the same group all the SIMM Bank article must have the same capacity.

For many PC machines for the different speeds if mixed into the SIMM with the article, even if they are the same capacity, may cause problems. For example, the CASIO np-20 Battery computer has been running at 60ns (nanoseconds) and 16MB of memory, if the free memory slot on the motherboard and then insert the SIMM 70ns speed section, the system will refuse to boot or is likely to start soon after the collapsed . For some computer terms, if the low rate of discharge to the first group of articles SIMM, you can solve the problem of speed of mixing, the computer will be the minimum speed of access.

For most PC machines, it must be a set of all the slots are studded with, or a set of all blank (of course not the first group), in a group can not just plug in the socket part of memory.

PC, the memory size of an acceptable upper limit (the maximum can be found from the PC machine manual. If there is no manual, the only way is to find the maximum value from the practice.)

SDRAM is a new generation of dynamic memory, also known as synchronous dynamic memory or synchronous SAMSUNG bp70a battery DRAM. Although there are many motherboard supports SDRAM and EDO memory mixing installation, but best not to mix. The reason is only 3.3V SDRAM voltage, while the majority of EDO memory will work at 5V supply voltage. While the board were on the DIMM and SIMM supply, but they are always together data line, if the SIMM (72 lines memory) and DIMM (168 lines SDRAM) mix, although the starting system can work, but used for a period of time, may cause SDRAM data input is damaged. Of course, if your SDRAM is suitable for wide-voltage (3V ~ 5V) work products, that no such damage.

4. If the fault has not been resolved, with the substitution check whether the memory is corrupted, and make the appropriate treatment.

5. If the above measures does not work, then suspect a problem with the motherboard or controller chip can be sent to Sony vgp-bps13a/b Battery professional  maintenance.
