Which of the following RAM types are compatible with PC2700 and maintain the same performance?
The correct answer is B. PC 3200. PC2700 refers to DDR SDRAM with a peak transfer rate of ~2700 MB/s (running at 333 MHz effective). PC3200 is also DDR SDRAM (400 MHz effective) and is physically compatible with DDR slots. When PC3200 is installed in a PC2700 system, it will downclock to run at the PC2700 (333…

Explanation
PC2700 refers to DDR SDRAM with a peak transfer rate of ~2700 MB/s (running at 333 MHz effective). PC3200 is also DDR SDRAM (400 MHz effective) and is physically compatible with DDR slots. When PC3200 is installed in a PC2700 system, it will downclock to run at the PC2700 (333 MHz) specification, maintaining the same performance level. PC2400 is DDR but slower, which would reduce performance. PC2-4200 and PC2-5300 are DDR2 modules, which use a different physical slot and voltage standard-they are entirely incompatible with DDR motherboards.
