When diagnosing potential RAM issues, which of the following should be checked for proper configuration?

The correct answer is A. Bus speeds. RAM modules operate at specific bus speeds (e.g., DDR4-2666, DDR4-3200), and all installed modules must be compatible with the motherboard's supported speeds. Mismatched or incorrectly configured bus speeds can cause system instability, failure to POST, or random crashes…

Explanation

RAM modules operate at specific bus speeds (e.g., DDR4-2666, DDR4-3200), and all installed modules must be compatible with the motherboard's supported speeds. Mismatched or incorrectly configured bus speeds can cause system instability, failure to POST, or random crashes. BIOS/UEFI settings sometimes need to be adjusted to match the RAM's rated speed via XMP/EXPO profiles. Fan speeds relate to cooling performance and are not a RAM configuration item. UAC (User Account Control) is a Windows security feature unrelated to RAM. CMOS battery voltage powers the BIOS settings retention chip but is not a RAM-specific configuration parameter.
