On a side note does MSI OverClocking Center/ GreenPower Center activates Active Phase Switch? and also how can you automatically lower the rpm of the fan in order make it quieter on startup ? Again thank you for your fast and informative answers.

  1. For the fans, check the hardware monitor section of the bios. You can enter the bios by holding the "del" key during the post, or F1 if instructed after a bios reset. On my msi board, the settings are 50-100%; I use 50 for the system fans, and 100 for the cpu fan. I set the smartfan speed at 12.5% for the cpu fan to keep it around 1000 rpm. I will accept higher temps to get a quiet system. On many boards, to unlock cores, simply set the "clock calibration" setting to "auto". If the system fails to post, you can try increasing the cpu voltage by .1 volts to maybe 1.4, and try posting again. If the post still fails or the system is unstable, then I wouldn't run it with the 4th core.
  2. All of the above+

    Have you got cool n quiet enabled in the bios and is your bios up to date?
  3. Yes I have enabled cool 'n' quiet feature .. as for the bios so far it is the latest one
  4. Have you tried unlocking yet?

    As far as fan noise goes I would buy a nice quiet aftermarket cooler.
