I have a ROG LCIII 360 AIO. My original plan was to get the Z790 Maximus Hero motherboard but my budget was too tight back then, so I ended up with the Z790-F. Is this board good for overclocking my 14900K?
i9-14900K is so fast natively that overclocking is of little use.
The better chips will have been already used in the 14900KS models.
Then, also, the default boost capability will boost a couple of cores past what an all core OC can achieve.
That is what a gamer wants.
Lastly, tinkering with voltages is what got the 1314th gen processors in trouble.
Whatever you do, update your motherboard bios to currency.
Be extremely careful with 14900k. Asus boards have many options that will let you kill your cpu chip. There was a fairly noticeable drop in the performance numbers when asus put out the bios update that prevents/reduces the 13/14th gen cpu from killing themselves. You can though turn on all those options manually. The 14900k if you disable the power limits will still constantly boast unti it hit the thermal limits even with the largest coolers you can find.
