CompTIA Server+ SK0-005 Practice Question

During a memory upgrade, a technician adds four 64 GB DDR4 load-reduced DIMMs (LRDIMMs) to a dual-socket rack server that already contains eight 32 GB DDR4 registered DIMMs (RDIMMs) operating at the same speed. When the server is powered on, it halts during POST with a fatal memory-initialization error and will not boot. According to common vendor memory-population rules, which corrective action will allow the server to start while letting the larger modules remain in service?

  • Replace all RDIMMs with LRDIMMs so every populated slot uses the same DIMM type and speed.

  • Reduce the memory clock speed in BIOS to the lowest speed supported by both DIMM types.

  • Install the LRDIMMs only in the channels assigned to CPU 0 and leave the RDIMMs in the channels for CPU 1.

  • Move the LRDIMMs to the priority (blue) slots and leave the RDIMMs in the secondary (black) slots within each channel.
