Solving Memory Problems
When trying any of the following, be sure to turn off the power. Be sure to perform a test on the system after any changes are made to verify that the problem has been fixed. Take note of any modifications so that you do not repeat them in the future.
Start by verifying that all modules are properly installed. Next, remove the modules one by one while ensuring that the guidelines for installing memory outlined earlier in this section are strictly adhered to.
One can try to improve DIMM performance by using a pencil eraser to clean the contacts or memory pins. Next, use compressed air, such as a blower, to remove any accumulated dust from the slot. Try again by inserting the module once more.
If these methods prove ineffective or the memory test detects a faulty module, the ideal solution is to replace it with a new one and then evaluate the system to ensure the problem has been resolved.
Memory Settings in BIOS
Certain BIOS configurations offer options for configuring memory. Usually, it is recommended not to make any changes to most of these configurations.
As mentioned earlier, the changes you can make to the memory configuration relate to the use of ECC/parity or non-ECC memory. In most cases, ECC/parity memory is considered unnecessary unless it is used on a file server.
One example where this configuration adjustment may be needed is if you have functional non-parity memory from a computer that cannot be repaired, and have another computer that requires similar memory of the same speed and type, which usually requires ECC or parity memory.
Assuming your BIOS allows it, switch the setting to non-parity/ECC before replacing the entire parity/ECC memory of an irreparably damaged computer with non-parity/ECC memory. Usually, it is recommended not to make any adjustments to the BIOS memory settings and leave them in their original state.
