Memory FAQ Topics
||If I have regular memory sizing error during POST (bootup), how should I trouble shoot the failure ?
||One of the most common memory problem faced in older PC system during boot-up is “incorrect memory sizing” or the error number 164. Sometimes failures could be caused by incorrect software setting, sometimes it could be caused by hardware – which could be easily fixed if you know where the faults lies.
In most cases hardware failures are caused by the natural aging process of the memory components, defective memory module socket, dirty contacts, cold solder joints during assembly and memory module not seated properly in the socket due to vibration.
It is important to pay attention to intermittent memory failure, before you make any expensive decision to replace the expensive memory - try cleaning the memory module contacts for both old and new ram to see if the problem can be fix:
Here ‘s the How to :
– Contact Clean (Purchase from local computer hardware store)
- Cotton Bud ( For cleaning contact with)
- Screwdriver (pc case removal)
- PC user manual
1 - ensure environment is static safe by removing any unwanted plastic, bags from your workbench. Keep the computer system plugged into your AC unit but ensure that the power switch on the PC is turned off. Keeping the PC plugged in the AC will ensure that case is grounded thus reducing the possibility of damaging the module or system from ESD (Electro Static Discharge)
2 -After removing the casing cover, ground yourself by touching any of the metal surfaces on your computer casing. Doing this step discharges any static built up on your body and clothing
3 - Visually locate the computer memory expansion slots. This is normal visible but if in doubt, refer to your operation manual instruction book.
4 – the first thing to do is to remove the memory module and perform some visual inspection to check the memory socket which sits the memory module. Make sure all the pins are straight, no cracks or broken pins must be found.
A Wet the end of a cotton swab with the solvent, the swab should be wet but not dripping
B Using a circular motion, clean the contacts on the memory module.
C Allow the contact surface to dry thoroughly.
D Replace the memory module into the socket.
E Repeat steps B through D for each module you have.
F Power on the computer to test the RAM.
G If you see no memory errors, replace the PC's case and power-up away.
5. While contact cleaner is preferred, it is also a well-known trick that you can also clean contacts with a pencil eraser.
6. Continuing RAM errors are usually a sign of a bad memory module. If cleaning the contacts doesn't solve your problem, try to isolate the faulty module and replace it.
