SK0-003 · Question #914

Which of the following is true about PC3-10600 RAM and PC3-10666 RAM? (Select TWO).

The correct answer is A. They both are compliant to the DDR3 specification C. They both operate at the same bus speed. Both PC3-10600 and PC3-10666 RAM modules are compliant with the DDR3 specification and operate at the same effective bus speed, with the numerical difference typically due to rounding conventions in their bandwidth rating.

Why each option

Both PC3-10600 and PC3-10666 RAM modules are compliant with the DDR3 specification and operate at the same effective bus speed, with the numerical difference typically due to rounding conventions in their bandwidth rating.

AThey both are compliant to the DDR3 specificationCorrect

The 'PC3' designation in both PC3-10600 and PC3-10666 explicitly indicates that these memory modules adhere to the DDR3 (Double Data Rate 3) SDRAM standard specification.

BPC3-10600 operates at a lower bus speed

PC3-10600 and PC3-10666 both operate at a 1333 MHz bus speed; thus, PC3-10600 does not operate at a lower bus speed.

CThey both operate at the same bus speedCorrect

Both PC3-10600 and PC3-10666 memory modules are rated for an effective bandwidth of approximately 10.6 GB/s, which corresponds to an operating bus speed of 1333 MHz, meaning they function at the same speed.

DPC3-10666 operates at a higher bus speed

Both PC3-10666 and PC3-10600 are essentially the same speed, 1333 MHz, so PC3-10666 does not operate at a higher bus speed.

EThey both are interchangeable with PC2-8400

DDR3 (PC3) and DDR2 (PC2) memory are electrically and physically incompatible, having different pin counts and voltage requirements, making them not interchangeable.
