How to boost the i5 9600k to 5GHz
Can the Asrock z390 phantom gaming sli/ac motherboard accommodate an Intel i5 9600k to 5Ghz processor?
Perhaps the outcome mainly hinges on the CPU rather than the motherboard. However, this graphics card won't limit you since it's a solid board. With proper cooling and quality silicone, you should reach 5ghz on it.
Probably not. My 9600K reaches around mid-70s with a Hyper 212 Black Edition, and I'm still at stock clocks. Most 212 coolers are about the same as the 120mm AIOs. Give it a shot. Check how far you can go before temperatures stop rising.
That is probably the best VRM available on an ITX z390 board. In fact its probably the best ITX board available for Intel period. Getting to 5ghz is going to depend on your chip. If you won the lottery and only need 1.25v to get there you'll probably be fine. Set your LLC to a point where there is only a slight drop on the VCORE when a %100 load is placed on it. If you can change the switching freq of your VRM turn it as high as you can go. This can help achieve more stable clocks at lower voltage in some cases. If you can upgrade to a bigger AIO it would definitely help.
