最近、サーバーが使用中にメモリ不足に関するエラー メッセージを送信し始めました。メンテナンス期間にメモリを追加した後も、サーバーの電源が常にオンの状態を維持できません。技術者が最初に確認する必要があるのは次のうちどれですか。
正解:A
When troubleshooting memory-related errors, it's essential to consider several key factors:
* Memory Compatibility: Memory modules must match the specifications supported by the motherboard (e.g., DDR4 vs. DDR5, ECC vs. non-ECC, buffered vs. unbuffered). Using incompatible RAM can cause boot failures, crashes, or instability.
* Memory Speed: While RAM speed mismatches can affect performance, they typically do not cause a server to fail to power on. Most systems automatically adjust to the slowest module.
* Memory Slots: Incorrect installation or damaged slots could be an issue, but the priority is to check compatibility first.
* Boot Order: This setting controls the sequence in which devices boot the OS, which is unrelated to memory-related power issues.
Since the server remains unstable after adding memory, the most likely issue is an incompatibility with the motherboard. The first step is to verify whether the newly installed RAM meets the server's hardware requirements.
