An administrator is adding an additional 1GB of memory into a server. The administrator notices that the system has 2GB of memory physically already installed; however, the server only shows 1GB of me

The correct answer is C. Two of the memory sticks are defective.. If a server physically has 2GB of memory but only reports 1GB during POST, the most likely reason is that one or more of the installed memory sticks are defective.

Question

An administrator is adding an additional 1GB of memory into a server. The administrator notices that the system has 2GB of memory physically already installed; however, the server only shows 1GB of memory during POST. Which of the following is the MOST likely reason for this?

Options

  • AThe OS does not support more than 1GB of memory.
  • BThe system memory has different manufacture dates.
  • CTwo of the memory sticks are defective.
  • DThe server is using memory interleaving.

Why each option

If a server physically has 2GB of memory but only reports 1GB during POST, the most likely reason is that one or more of the installed memory sticks are defective.

AThe OS does not support more than 1GB of memory.

The operating system's memory support is irrelevant during POST, as POST is a hardware-level diagnostic test that executes before the OS loads.

BThe system memory has different manufacture dates.

Different manufacture dates for memory sticks do not inherently prevent them from being recognized, as long as they meet the required specifications and are compatible with the motherboard.

CTwo of the memory sticks are defective.Correct

When a server physically contains 2GB of memory but only recognizes 1GB during the Power-On Self-Test (POST), it strongly indicates a hardware issue with the unrecognised portion. This commonly happens if one of the two 1GB memory modules is defective or not properly seated, preventing the system from detecting its full capacity.

DThe server is using memory interleaving.

Memory interleaving is a performance optimization technique that structures memory access, but it does not reduce the total amount of physically installed memory that is reported by the system during POST.
