You need to replace memory in a desktop PC and to go to purchase RAM. When you are at the store, you need to find the appropriate type of memory. What memory chips would you find on a stick of PC3-16000?
A. DDR-2000
B. PC3-2000
C. DDR3-1600
D. DDR3-2000
DDR3-2000
Remember the 8:1 rule. Modules greater than but not including SDR SDRAM are named with a number eight times larger than the number used to name the chips on the module. The initials PC are used to describe the module; the initials DDR are used for the chips; and a single-digit number after PC and DDR is used to represent the level of DDR. The lack of a single-digit number represents DDR as long as the number that is present is greater than 133 (such as PC1600). Otherwise, you’re dealing with SDR (such as PC133). This means that PC3-16000 modules are DDR3 modules and are populated with chips named DDR3 and a number that is one-eighth of the module’s numeric code: 2000.
