Can i overclock without changing voltage?

Hey everyone.

 

So i have the i7 9700k which runs at 4.9 Ghz. I wanted to know can i simply just change the multiplier to 50 for all cores and leave the voltage to auto plus everything else.

Auto voltage will apply more than you will need, usually resulting in hotter temps. If you do leave it at auto voltage, make sure you use software to evaluate the voltage and temps in a stress test to make sure it's suitable 

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

Yes, but you will most likely have more then required voltage being supplied to the CPU.

8700K @ 5.2ghz 1.29V, 4x8 Rev.E @ 4040 13-20-20-39 1.7V.

Thank you. So if i want to change voltage. What is a good base to start for just 50 to 51ghz?

Depends on your performance target, 4.6GHz is the all core turbo so 5.0 all cores is a decent step up, and if it suits your needs then it's a good point to stay at.

You can probably try around 1.22 volts and see from there

I have the same CPU.

I just turn on Turbo Boost and Multi Core Enchantment.

4.9Ghz on all cores, the voltage never went above 1.27v ich 5 months now!

That is a impressive voltage for that OC.

On an 8700k, it is, but a 9700k wouldn't need that much usually.

1.27v should be like a 5.1-5.2GHz OC on a 9700K. For 4.9GHz should be about 1.12-1.14v.
