Question

Why doesn't my computer detect all new memory?

Answer

This question was answered on April 11, 2003. Much of the information contained herein may have changed since posting.

This issue could be caused by any of the following:

Memory not setup properly in CMOS

Computer does not support as much memory as you are attempting to add

Memory incompatibility

Bad computer memory

Solution:

Memory not setup properly in CMOS

Ensure that the computer memory is properly setup within CMOS The computer will only be able to detect what is defined in CMOS Note: most new computers should auto detect this value, however insure the auto detect is properly set

Computer does not support as much memory as you are attempting to add

Verify through documentation or through the computer or motherboard manufacturer that that your computer is capable of supporting the amount of memory you are attempting to add Many computers may not be able to support large amounts of memory exceeding 128, 256 or 512MB of memory

It is possible that the manufacturer of the computer or motherboard may have a BIOS update which may also correct issues with the computer detecting more memory or allow the computer to accept more memory

Memory incompatibility

If the computer is capable of supporting the amount of memory you are attempting to add into the computer verify the new memory is compatible with the existing memory or that you are installing the correct type of computer memory.

Because of the possible differences in computer manufactured motherboards this information must be obtained either through the computer manufacturer of documentation on the computer motherboard

Bad computer memory

If none of the above recommendations have been reviewed and do not apply or did not resolve your issue it is possible that the computer memory you are attempting to install or the computer motherboard may be bad
