The memory non-upgrade

You have upgraded the memory in a computer from 1 gigabyte to 2 GB. For the upgrade, you replaced two 512 MB DIMMs with two 1 GB DIMMs. Unfortunately, when you boot the computer the BIOS memory check only shows 1 GB of RAM. What is the most likely cause of this problem?

A) The BIOS must be upgraded to recognize the upgraded memory

B) The BIOS must be reconfigured to recognize the upgraded memory

C) One of the memory sticks is faulty or the incorrect type

D) 1 GB memory cannot be installed in pairs

E) I was told there would be no math

The answer: C) One of the memory sticks is faulty or the incorrect type

Memory is a component with very little tolerance to incorrect specifications. If memory is just a little bit off, it won’t work at all. When upgrading memory, you should always check your computer or motherboard specifications and cross-reference those specifications against the memory that you are purchasing. Most online memory stores have detailed memory guides, but even those guides can occasionally have errors.
