So I'm new to the hardcore PC enthusiast community. Can anybody explain to me in simple layman's term on how to overclock my CPU and Memory.

So when I go to my BIOS settings, I can go to the core ratio and set it to 4GHz or higher right? My CPU is a Ryzen 5 1600X clocked at base speed at 3.6GHz with a 16GB (2x8GB) 3000 MHz memory on my Asus STRIX B350-F GAMING motherboard. But when I do that, I also need to increase the cpu voltage and just keep increasing the increments a little bit until it's stable. I learned a cool trick that you can do to increase the increments of the voltage is by using the + or - button on your keyboard. Okay I understand all that, but what I don't understand is what do people mean when they say "until it is stable". What am I looking for in "stable" when I'm playing my games or just running the computer in general. Am I to make sure that the computer does not crash, my mouse is not suppose to lag. Can somebody explain to me what am I looking for in "stable"?

And lastly, how do I overclock the memory? Same principle? So right now, my memory is clocked at 2400MGHz and I would like to get my memory to clock at 3000MHz or higher if possible.

Thanks! Please make your instructions as simple as 1, 2, 3, meaning as straightforward as possible. My pet peeves is that I'm the kind of guy that just prefers a straight to the point answer instead of reading an essay worth of answer. So please make it as simple as a 1, 2, 3 step guide.

Explain the reasoning for the voltage increments and what am I looking for in stabilizing it. Then give me a 1, 2, 3 step guide.
 
Solution

Getting positive air flow
plz use velcro strap or zip tie so intake fan won't be blocked by PCIe & 24pin cable, add top exhaust fan, and another front intake. Or move front intake as top exhaust and get 2 140mm case fans as intake.
Why, I underestimate positive air flow, my EVGA Z97 Classified pay the price. Turn out that it VRM heatsink weren't sufficient enough at OC operating state.

Did you change the load line caibration?
"Stable" is usually determined with stress testing software such as Prime95 or AIDA64.

If you run the test and your computer crashes or freezes, then it is not stable. How long you should run the test is typically up to you, but 20-30 mins is what I usually consider stable. Other people will say longer, like 24 hours. But I think that's unnecessary stress on the system. If stability is that important, you probably shouldn't be overclocking.

More voltage can allow the same speed to become stable if it previously crashed. But more voltage will create more heat, and too much heat will kill your components. DDR4 RAM has a max of 1.4V, and your CPU is somewhere around 1.45V (I think, double check).

Use small increments

1.) Increase speed

2.) Stress test

a.) if passed, increase speed again

b.) if fail, increase voltage

with RAM you have other variable besides speed and voltage, that is timings. You can increase timings along with voltage to allow faster speed.

Typical DDR4 RAM speed, voltage, and timings are

2400 1.2V C16 -- increase voltage to 1.35V and see what speed you can get 2666, 2800, or 3000

or if you have 2400 1.2V C14 you might get 3200 1.35V C16

Prep

    ■ PSU, related to your UPS, if you happen to use 80+ gold 600 W (~82 to 85% efficient), you need at least 800 W UPS, where 82% active power factor correction on 600 W PSU will draw ~ 700 watt from socket wall.
    ■ Room temp, some ICs will have longer life span on 20 to 25 deg C moving air, get as many section inside your case have sufficient air flow.
    ■ BIOS update, always use latest BIOS, more of this on RAM OC.

Knowing the limit
Set the highest voltage related option available, unlike others who advise of increase bit by bit, I'd just go for 100% LLC or highest level, unless you plan 24/7 OC then start by 25% should be good.

my aggressive stable voltage threadripper 2950x with POB enabled
vcore 1.45
SOC 1.3
vdimm 1.35 to 1.45
PLL 2.0
SB 1.4
standby 2
SB 2.5

    ■ On BIOS, select OC, you should see child menu

    CPU Load Line Calibration Control [Auto]

    by default all voltage related settings was set to auto, the increased voltage ensured higher clock speed will be stable on system stressing

    ■ Save and exit BIOS, after windows login check via CPUZ and then run benchmark
    ■ If you stumbled on freeze or BSOD, just redo the steps and change each one of 'em

Have a look at my system. https://pcpartpicker.com/b/XDfH99 My PSU is an EVGA SuperNOVA G3 650W 80+ Gold Certified Fully-Modular.
