CPU and Memory Overclocking
The video below describes the steps necessary to achieve a simple 5Ghz overclock with XMP using the SuperO Booster application.
The SuperO Booster is currently only offered on their Z270 chipset motherboards but will be available on their X299 offerings when those motherboards are released. The first thing you want to do is pick your battle. I highly recommend overclocking your CPU first and then moving on to memory overclocking. That is particularly the case with the Z270 platform, where memory and CPU overclocking don't really interfere with each other.
I would start at 1.3v VCore ("VCPU(V)") and 4.8GHz on all cores. Most 7600Ks and 7700Ks reach their maximum stable frequency around 1.3v with a decent cooler, but sometimes there is a little wiggle room. The CPU's temperature will be your limiting factor. You will probably have to manually set LLC too, but I will talk about that later down in the guide.
The SuperO Booster allows for per-core overclocking or all cores at once. To save time, you can drag the bottom slider on the 4th active core to an overclocked multiplier; I would start at 47x or 48x. You can overclock with BCLK as well, but most people just prefer multiplier based overclocking as it's simple and easy. You need to leave EIST and Turbo Mode enabled if you want your CPU to overclock. If you want your CPU to almost always run at maximum frequency, you need to change your Windows Power Plan to "High Performance." You might also want to raise your CPU Warning Temp to 80C, and you can also increase your VCore (VCPU), or wait until we reach the voltage page.
You can also apply different overclocks to different cores, meaning you can run two cores at 49x and two at 50x if that helps with stability. Once you "Apply" the CPU multiplier, the effects will happen in real-time, so don't hit apply unless you have already increased your VCore (VCPU). If the system is totally unstable, the motherboard will reboot and reset your settings. If you find your overclock is unstable then you need to tweak voltages, but you also have one other weapon; Load Line Calibration (LLC).
LLC will reduce voltage drop under load. For example, if I set 1.3v, I might get 1.3v at idle, but when I apply a load, the VCore voltage will drop in proportion to that load, perhaps as low as 1.22v. LLC reduces or reverses this voltage drop, and greatly helps with stability when overclocking. The SuperO Booster application offers LLC levels 1-7 as well as Disable and Auto modes. Level 1 is the strongest and will result in the voltage actually increasing under load. Level 2 offers a slight minimal drop in VCore, and the drop gets larger as you get closer to level 7. I recommend Level 2 or 3.
