Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
You boot a system that has 16 gigabytes (GB) of Random Access Memory (RAM) configured in four 4 GB dual in-line memory modules (DIMMs), but during power-on self-test (POST) you notice that the system only shows 12 GB RAM total. How do you troubleshoot this problem?
A
Test the memory DIMMs and memory slots
B
Correct the RAM DIMM sizes and counts in the BIOS
C
Power cycle the system until the correct RAM amount appears
D
Run a loopback test on the system to test the motherboard
Explanation: 

Detailed explanation-1: -One bit in the register can reference an individual byte in memory, so a 32-bit system can address a maximum of 4 GB (4, 294, 967, 296 bytes) of RAM.

Detailed explanation-2: -The best method of determining the memory (RAM) to use with your computer is through the computer or motherboard manufacturer documentation. If you do not have your product documentation, you can find it online through the computer manufacturer or the motherboard manufacturer website.

Detailed explanation-3: -B. Remember the 8:1 rule. Modules greater than but not including SDR SDRAM are named with a number eight times larger than the number used to name the chips on the module.

Detailed explanation-4: -DIMM (dual in-line memory module) is a type of computer memory that is natively 64 bits, enabling fast data transfer. DIMM is a module that contains one or several random access memory (RAM) chips on a small circuit board with pins that connect it to the computer motherboard.
