Question: 1 / 525

PC-3200 has a voltage of?

2.5V

The correct answer is 2.5V. PC-3200 refers to a specific type of DDR (Double Data Rate) SDRAM memory, commonly used in computer systems during the early 2000s. This type of memory typically operates at a voltage of 2.5V, which is a standard for many DDR SDRAM modules.

Understanding this voltage is important, as it reflects the electrical requirements that ensure proper communication between the CPU and the RAM. Selecting or configuring memory modules that have the correct voltage is crucial for system stability and performance.

The other voltage options are associated with different types of memory or technological standards. For example, 1.8V is commonly seen in newer DDR2 and DDR3 memory, while 1.5V is typically used by DDR3 memory modules. 3.3V was used in older SDRAM types before DDR technology became widely adopted.
