Overclocking and tweaking

Overclocking and tweaking by BIOS

When you plan to overclock the processor, always invest in good hardware. And that includes a proper motherboard, power supply, memory, and of course, cooling. Cheaper motherboards are often not well-tuned or designed in terms of power delivery for enthusiast overclocking. That can translate into a lesser power delivery (phases) design quickly warming up the related components, causing instability. Also, never underestimate the benefits of a quality power supply. When you tweak a processor, depending on what you are trying to achieve, you often need to add voltage to the processor, which creates more heat. Ergo, proper processor cooling is mandatory.

Overclocking with a many-core processor (doesn't matter if that is Intel or AMD) is often more difficult to accomplish. If you overclock by BIOS (which 99% of us do), really, it all comes down to the quality of the BIOS (mobo brand) and merely a few registers you need to fiddle with. Remember that we're going for an all-core overclock, which means a lower clock frequency than the highest Turbo bin offers. What you need to do:

  1. Enable and start at 4200 MHz (42 Multiplier)
  2. Apply 1.40~1.50 to the CPU (or leave it at auto)
  3. Work your way upwards from there until the system becomes unstable and then back down at least 100 MHz.
The new ZEN3 processors have been pushed to the max. We reached a stable all-core 4700 MHz on all Series 5000 processors; some might be able to hit 4800 MHz. 


The processor scores 6270cb (at defaults that is 6112cb) so that's 2~3% and not worth the overclock.
