Which statement is true about the HP Z440, Z640.and Z840 Desktop Workstations?

Question

Options

• AThey require the DDR4 memory architecture.
• BThey require the DDR3 memory architecture.
• CThey allow swapping between the DDR2, DDR3, and DDR4 memory architecture.
• DThey allow swapping between the DDR3 and DDR4 memory architecture.

• A
  7% (2)
• C
  3% (1)
• D
  90% (27)

Explanation

Option D is correct because the HP Z440, Z640, and Z840 workstations are designed with flexible memory support, allowing administrators to use either DDR3 or DDR4 RAM - a useful feature for organizations transitioning between memory generations or managing component costs.

Option A is wrong because requiring only DDR4 would be too restrictive - these platforms maintain backward compatibility with DDR3. Option B is wrong for the opposite reason: DDR3-only would exclude DDR4 support, which these workstations do support. Option C is wrong because DDR2 is an older, incompatible standard not supported by these platforms; the flexibility stops at DDR3.

Memory tip: Think of the Z-series workstations as "bridge" platforms launched during the DDR3-to-DDR4 transition era - they bridge two generations (3 and 4), not three, and they never reach back to DDR2.
