CPU Speeds, Multiplier, Performance Etc.

• In computing, the clock multiplier (or CPU
  multiplier or bus/core ratio) measures the ratio
  of an internal CPU clock rate to the externally
  supplied clock. A CPU with a 10x multiplier will
  thus see 10 internal cycles (produced by
  PLL-based frequency multiplier circuitry) for
  every external clock cycle.

Replace a CPU

• Ill list 12 steps to replace a Servers CPU
• Shut Down and remove power from the entire system
• Remove the server node from the system.
• Remove the server cover
• Use the proper tools to remove the heatsink
  usually a Philips screwdriver
• Unclip the first CPU retaining latch and then
  unclip any remaining latches
• Open the CPU hinged CPU cover plate
• Remove the old CPU
• Insert new CPU
• Install the heatsink (Remember to replace the
  thermal grease/paste that goes between the CPU
  and heat sink failing to do this will cause the
  CPU to overheat and fail)
• Replace the Server cover
• Reinstall the server
• Replace power cords and then power on the system.

Random Access Memory
Most non-ECC memory cannot detect errors although
some non-ECC memory with parity support allows
detection but not correction.
