What voltage does DDR2 RAM operate at?

2.5V
1.8V
3.3V
1.5V

The correct answer is: 1.8V

DDR2 RAM operates at a voltage of 1.8V, making option B the correct answer. This technology replaced DDR1 RAM, which operated at 2.5V (option A). Option C is incorrect because it refers to the voltage used by earlier generation RAM. Option D is also incorrect because it is the operating voltage for DDR3 RAM. It is important to know the correct operating voltage for your RAM in order to ensure proper functioning and avoid any potential damage.
