New PC Overclocking Questions

[Nziak]

So I have a few general questions, being new to this kind of stuff. 

 

1) I have a 9900k and a aorus ultra motherboard. This board has an 8+4pin eps connector, but I am only utilizing the 8pin connector. Do I need to have both of them connected for overclocking, and if so, what do I need to do for an 8+4 connector because my PSU (Corsair RM750x) didn't come with one.

 

2) when overclocking do you have to push it to it's max, or can I go say to 4.5ghz. what are your recommendations? The thought being is if you overclock doesn't it lessen the lifespan of the chip?

What board is it specifically? Does the PC work with only 1 8 pin? 

 

For numbers, Every CPU is different, But you can overclock to whatever you feel you like, Your performance will only go up, I dont know the 9900k Inside out, But the Boost is 5GHZ so, So you could most likely run 4.5/All cores and be stable, However like I said every chip is different.

 

Overclocking wont really reduce lifespan, And if it did by the time it died, Which doesnt happen often to cpus, The chip would be significantly out of date, Would you be upset about a dead core 2 duo? The performance improvement is significantly better the extremely long lifespan of the CPU

If im correct, voltage is what kills a CPU, along with high temperatures. As long as the voltage is not too high, then it should be OK.

It will degrade the chip, over time you will need more and more voltage to keep the same clock speed, its a positive feedback loop unfortuntaly until the voltage fires the silicone. 

But I doubt that you will have this issue, as I haven't on my amd chip running at 1.38v pretty much everyday for a year and a half or so

1) no it doesn't. Assuming Corsair didnt give you cheapo wires, a 8pin EPS connector can provide at least 400W of power. You're not reaching anywhere near that power draw even when liquid nitrogen overclocking the 9900k

 

2) I just crank the frequency and voltage higher and higher until the temperature in stress test goes past 80C or voltage goes past 1.4V

Thank you guys for the input. I have another question. I ran 3d mark time spy and got a 10566 overall with a RTX 2080 (Asus strix oc) score of- 10665; and my i9-9900k scored- 10042. My question is, is this average, below average? This is my first build and just want to make sure it is working right.
