Common problems that often occur in RAM

Why does a mistake occurs after I install new RAM?
You can look at the manual booknya. For a quantity of the BIOS: In case you are installing (eg) 2-4 Mb 2-8 Mb Simms and Simms, you ought to put bigger RAM in bank.


After adding RAM, why RAM is detected still the same?
After you install the RAM, you ought to re-do the BIOS Setup. The trick, the first time you turn on the computer until the BIOS logo appears, press Del (for some computers may Ctrl + Alt + Del or other key combination). When completed, select Save Settings and Exit. 


Why do posts appear Parity Check Error?
Writing a parity check error may occur if there is destroy to of the RAM, of the DMA not working, or because there is parity boot virus on your hard disk.

After I install new RAM, why frequent Blue Screen?
On computers that use the bus 66 MHz (Pentium 133 or higher), it takes the RAM with a speed of 60 ns or higher. You can only use RAM with a speed that is less than 60 ns but you need to change settings in the BIOS Wait State. Change the setting from 0 to 1.


Why does Windows detect the RAM is less than the actual thing? 

1. Phsically damaged. To overcome this you must check the physical condition of the RAM. Open your computer case, then take off the RAM. Neat if dirty RAM & socket. Also check if there is rust. You ought to also make positive that the RAM of the same material (golden or silver). If different, you ought to replace the RAM.
2. In some BIOS, ROM shadowing & 16 bit drivers, sometimes wearing some (read: tiny) RAM before Windows starts. There's also some BIOS ROM shadowing feature that will copy the contents of the technique & video BIOS ROM in to RAM in order to improve computer performance (On DOS & Windows three.1). This is because the speed is lower ROM than RAM. But in the event you are using Windows 95/98/NT with minimal memory ROM shadowing feature ought to be turned off (from the CMOS setup), because Windows 95/98/NT never access the ROM so that RAM can be used by Windows.
3. The use of the VGA card on board. If for example you have 32 Mb RAM & three MB VGA card, the RAM can be used as much as 30 Mb (32 Mb - three Mb). So you ought to not use the VGA card on board.
4. There's drivers or programs that run from config.sys or autoexec.bat that works using the RAM. The solution: Edit the autoexec.bat & config.sys files using Notepad. Then edit the line that "suspicious" or are roughly used to load the program. When you see you add the word REM (but in the event you add the word REM then the program won't di-load/dijalankan). When you wear a 4x CD-ROM driver from TEAC, change the parameters xmssize = -1 in the autoexec.bat to xmssize = 0.
5. Virtual device driver walking from technique.ini. To fix this open the technique by clicking Start - Run - type SysEdit. Select the Technique.ini. Then edit the line that roughly used to load virtual device driver. Another alternative is to generate a new Technique.ini file.
6. There's lines in the Technique.ini file Maxphyspage refer to the Technique.ini file, whether or not there is a line Maxphyspage. If so, delete that line.
7. Errors in the CMOS settings. On some computers there's features of the Memory Hole at 16 Mb or Hold to 15 Mb of RAM. If the feature is enabled so in the event you have a bigger RAM of 15 Mb or 16 Mb, Windows will still detect as much as 15 Mb or 16 Mb. To overcome this, disable these features.
8. Load Ramdrive.sys from config.sys Check your Config.sys file for a line containing "Ramdrive.sys." In the event you have this line, it means you are using a RAM drive. To disable the RAM drive, remove or disable the line in the Config.sys file contains That "ramdrive.sys." To disable the line, use a text editor (Such as Notepad) to edit the Config.sys file & place a semicolon (;) at the beginning of the line. Open the config.sys file with Notepad. Check on the file, whether there is a line ramdrive.sys. If so, delete the line
