SSD Installation Tips

  • M.2 heatsink: Most B860 boards include M.2 heatsinks — remove them before installing, then reattach
  • PCIe generation: Check which slots support Gen 4 vs Gen 5 — the CPU-direct slot is usually fastest
  • BIOS setup: New SSDs may need to be initialised in Windows Disk Management after installation
