Question How can I set to 5 GHz for 9900K?

[colat]

9900K has 3.6 GHz by default. How can I overclock it to 5GHz from bios? Is it cpu cooler depandant? I am using regular/normal cpu cooler.

CPU cooler, motherboard and psu are very important. What do you have?

I’d recommend Googling overclocking guides, you will get a far more detailed answer than what anyone can post hear. Do lots of reading before you start.

asus z390, corsair psu

What exact Asus motherboard and Corsair PSU. Both have good and bad models. A 9900k needs everything to be high quality.

What's a regular/normal cpu cooler?
9900k @ 5.0ghz = 360mm AIO, or custom loop.

Cheap one, 5$

Seriously...?
And this cooler can maintain the 9900k's 4.7 all-core boost clock?

I'll believe it when I see it...

The '3.6 GHz clock speed' is pretty much a minimum boost, and most heavy loads that invoke all threads would likely see 4.6 GHz boost, if power budget /TDP and cooling are adequate... You would see intermittent boosting of 1 or 2 cores at a time to as high as 5 GHz as normal operation...

CHeck HWMonitor while running CPU-Z/bench/stress CPU for a few minutes, then see what max clock speeds are maintained across all cores. (Look for 4.6 GHz)

Assuming a very good cooling solution is acquired, and adequate core voltage is being applied...

Asus Z370/Z390 mainboards have MCE mode in the BIOS, which, when enabled, will allow all core turbo to go to as high as the normal max 1 and 2 core limits of 5 GHz... (Advisory: don't attempt this with some factory junker cooler from an i3-6100, etc... ; if your CPU temps in CPU-Z/bench/stress CPU are already at 80-85C when at all-core 4.6 GHz, you are too warm already, and need not waste your time worrying about fantasies of all-core 5+ GHz action ...)
