Which packaging is used for DDR SDRAM memory?
- A.168-pin DIMM
- B.72-pin SIMM
- C.184-pin DIMM
- D.RIMM
- Answer & Explanation
- Report
Answer : [C]
Explanation :
Explanation :
| DDR SDRAM is manufactured on a 184-pin DIMM. DIMMs with 168 pins were used for SDR SDRAM. The SIMM is the predecessor to the DIMM, on which SDRAM was never deployed. RIMM is the Rambus proprietary competitor for the DIMM that carries DRDRAM instead of SDRAM. |

What memory chips would you find on a stick of PC3-16000?
- A.DDR-2000
- B.DDR3-2000
- C.DDR3-16000
- D.PC3-2000
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
| 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. |
