ユーザーのデバイスにメモリがさらに必要なため、技術者は次の仕様で追加のRAMをインストールします。 2 x8Gb DDR3-1066(PC3-S500) 1 x 16Gb DDR3-1333 (PC3-10600) 次の速度のうちどれが信頼性を最大化しますか?
正解:A
When multiple RAM modules with different speeds are installed in a system, the system will default to the speed of the slowest module to maintain reliability and stability. In this case: The system contains two DDR3-1066 (PC3-8500) modules and one DDR3-1333 (PC3-10600) module. The slowest RAM speed is DDR3-1066 (PC3-8500), and the system will run all memory modules at this speed to prevent timing mismatches and data corruption. Key Concepts: Backward Compatibility: RAM modules with higher speeds can operate at lower speeds when mixed with slower modules. Reliability vs. Performance: Operating all modules at the slowest speed ensures stability, especially when modules have different specifications.
