Zorluk: Çok zorCPU Architecture Cooling and Sockets

A system technician is upgrading a high-density virtualization server host from an older processor to a modern multi-core x86_64 processor. The motherboard utilizes a Land Grid Array (LGA) socket architecture. During the installation planning, the technician must also verify thermal management and hardware-assisted virtualization support. Which combination of architectural characteristics and installation procedures correctly describes this processor deployment?

  1. The socket pins are located on the motherboard rather than the CPU package; hardware-assisted virtualization (VT-x/AMD-V) must be enabled in UEFI/BIOS, and a thin layer of thermal compound is required between the CPU integrated heat spreader and heatsink.Cevap
  2. B
    The socket contains grid holes that accept delicate pins protruding from the underside of the CPU package; thermal paste must be packed directly into the socket holes prior to lowering the Zero Insertion Force (ZIF) arm.
  3. C
    The processor package is permanently surface-mounted via solder balls directly to the motherboard; hardware virtualization is handled entirely through software emulation without motherboard firmware dependencies.
  4. D
    The LGA architecture routes pins from the CPU package into socket receptacles; thermal paste is only used on passive heatsinks and must be omitted when installing an Active All-in-One (AIO) liquid cooling block.

Cevap

In Land Grid Array (LGA) architectures, the spring-loaded pins are situated directly within the motherboard socket. Bare-metal 64-bit hypervisors require enabling CPU hardware-assisted virtualization (Intel VT-x or AMD-V) in the system UEFI/BIOS, and thermal interface material (TIM) must be applied between the CPU's Integrated Heat Spreader (IHS) and the heatsink or cold plate.
Land Grid Array (LGA) sockets feature pins on the motherboard socket rather than on the processor packaging. Deploying a virtualization host requires enabling hardware-assisted virtualization (VT-x/AMD-V) in system firmware, and thermal compound must always be applied between the CPU integrated heat spreader and the thermal block to facilitate heat transfer.

Adım Adım Çözüm

1
Identify the physical architecture of an LGA socket.
Confirm that LGA sockets house pins on the motherboard socket grid, whereas the processor underside features flat conductive pads.
Prevents mistaking LGA features for PGA (pins on CPU) or BGA (soldered chip).
2
Determine thermal interface requirements.
Verify that thermal compound is required to eliminate air pockets between the processor IHS and the cooling surface regardless of active, passive, or liquid cooling methods.
Air is a poor heat conductor, leading to rapid thermal throttling if thermal compound is omitted.
3
Analyze firmware prerequisites for 64-bit guest virtualization.
Identify that Intel VT-x or AMD-V extensions must be toggled on within the UEFI/BIOS settings.
Type 1 hypervisors require hardware-level virtualization support to run 64-bit guest operating systems efficiently.
