What can you tell from reading the label on an HP DDR4 DIMM?

Question

Options

• ANumberofDIMMsinstalled, total memory installed, and aggregate speed
• BNumberofDIMMs, maximum memory capacity, and number of pins
• CMaximumspeed, type of DIMM, number of ranks, and width of DRAM
• DConfigurationof pins, number of processors, and supported operating systems

• A
  95% (35)
• B
  3% (1)
• D
  3% (1)

Explanation

Option A is correct because an HP DDR4 DIMM label (as presented in HP's certification context) conveys system-level memory information: how many DIMMs are installed, the total memory capacity across those DIMMs, and the aggregate operating speed - giving a quick snapshot of the memory configuration in the system.

Why the distractors are wrong:

• B is wrong because the number of pins is a fixed hardware characteristic of the DDR4 standard, not something read from a label, and maximum capacity refers to the system, not what a label reports.
• C describes information more typical of a raw JEDEC or manufacturer spec sheet (rank, DRAM width), not what HP's DIMM label surface communicates to the technician.
• D is entirely off - pin configuration is a physical standard, processor count and OS support are not DIMM label data at all.

Memory tip: Think of the HP DIMM label as answering the three "how many/how fast" questions a server tech asks first: How many DIMMs? How much total RAM? How fast is it running? - Count, Capacity, Clock. The three C's you'd check before troubleshooting a memory issue.
