Any tips on changing the bus speed if I am changing the multiplier to x 21.0

Overclocking this CPU will cause its power consumption to go up dramatically, so I hope that your motherboard can support that.

My motherboard can handle it, it's unlocked and motherboard can adjust the multiplier to any amount I need to adjust the bus speed also. Thanks for input.

No, he means the power delivery on your motherboard. What motherboard do you have?

Thats your MoBo's BIOS

get an aftermarket cpu cooler and disable 4 cores.

What cooler, PSU, and CPU power cable do you use?

Thank you, BreakPoint!

My question has not been answered all your posts are spam.
again what bus speed should I adjust to get 4GHz

I will stop asking important questions, then, since you consider them to be spam...

Your CPU is "unlocked", so you do not need to adjust the base clock speed, just the CPU's multiplier.

According to the following link, your motherboard has 4+2 phases, so it might not allow your power hungry CPU to overclock too much:

Thank you for clarification on the "base clock speed"
