How much memory can be installed in the HP Z620 Workstation with two CPUs?

Question

Options

• A32 GB
• B48 GB
• C96 GB
• D128 GB

• B
  4% (1)
• C
  93% (26)
• D
  4% (1)

Explanation

With two CPUs installed, the HP Z620 activates all 12 DIMM slots (6 per processor), and using 8 GB DIMMs across all 12 slots yields a maximum of 96 GB - making C correct. Option A (32 GB) is too low and doesn't correspond to any standard Z620 configuration. Option B (48 GB) is the single-CPU maximum (6 slots × 8 GB), a common trap for test-takers who confuse single- and dual-processor configurations. Option D (128 GB) is not achievable with the Z620's 12-slot architecture using standard 8 GB DIMMs.

Memory tip: Associate "2 CPUs = 12 slots = 96 GB" - doubling the processors doubles the slots, but the answer isn't simply double the single-CPU max (48 × 2 = 96), which helpfully confirms the math.
