New to overclocking

[R3dAlert93]

Kinda new to overclocking and just wondering whats recommended to put into msi afterburner. What should i set the core clock speed and memory clock speed for my rtx 4080?

It`s recommended (at least by me ) to not mess with trying to overclock 4000 series GPUs and just take them as they are. Gains from that would be basically useless anyway since you wont gain any significant numbers by that.
It`s not the good old overclocking times of ten years ago when manufacturers still made the cards with actual headroom for overclocking.

I guess it stresses the gpu more and gives it a shorter lifespan

Only thing I do nowadays is undervolt as less juice = less heat which means lower fan RPM.

Have my 3070 Ti undervolted down to .950 at the same clockspeed that it's factory settings has going above 1.237. I've had it run at + 100 clock and +1000 Memory whilst voltage set a 1.0
Even then it has been known to boost above what is set.

So does using it versus leaving it in the box. This is one of those "people like to say it because it sounds like something", but they can't in any way quantify it beyond the vaguest of the vague"

How much "stress" how much shorter of a "lifespan". An hour, a day, a week out of how much time?

I would say that with most current hardware, there's not much headroom for overclocking. You can still do it if the process itself is entertaining to you. But if you're doing it to gain performance, it's pretty much a waste of time. At least that's what it feels like when you lived through a period of time where you could get another Ghz out of a CPU through OCing with a $40 air cooler. Those days are gone.

Nothing wrong with Overclocking, its practically expected these days, his assumption is incorrect.

Now to answer your Q
First of all, raise the power/temp limit to max, they tend to be linked so raising one raises the other as well.

As for overclocking, Raise the core and memory clocks by 25-50Mhz and click apply, either benchmark the GPU or play a game to make sure its stable and doesnt crash, then raise the clocks again and do the same thing.

When overclocking the Core its usually always a lower amount than what the Memory can safely be overclocked to, for example, Core +90, Memory +250 etc so on, Memory will always allow for a higher overclock, so keep that in mind, dont OC the Core higher than the Memory to avoid issues.

With that said, you could easily look up Overclocks for that GPU and replicate them to the same OR slightly lesser overclock.

Techpowerup have a review [www.techpowerup.com] of your GPU, and this page contains the overclocking results. Short answer is you only have around 5% of headroom available.

Raising the power limit and memory clock is the easiest thing to do and adds maybe 2%. The rest, as others mentioned, is achieved by tweaking clocks and will involve a lot of benchmarks and tests.

If you still want to get serious, here's a guide [github.com] I found that contains much more detail that I can ever come up with.

In general, Nvidia GPUs have a lot of hardware limitations/monitors that make GPU OC pointless.

That is DEFINITELY NOT True
No idea where you learned that from but that is absolutely Incorrect

In my experience with the 4080 you wont get much on the core clock under air cooling (200ish Mhz) but you can crank the memory clock up over 1Ghz,

[[☥] - CJ -]

Core clock is always going to be lower than what the Memory is capable of overclocking to, always been like that.

[_I_]

you never got much from overclocking the gpu cores anyway
overclocking their ram made a bigger difference

[Introverted Gamer]

Core Overclock isn't really worth it these days. Memory Overclock and Undervolt is what most are doing.

We substantially increase the benchmark performance by manually overclocking the GPU core and memory. The highest improvement is +22.50% in Unigine Superposition. To my surprise, the DLSS Feature Test performance also increased. To clarify, that means the increase in FPS with DLSS enabled goes up faster than with DLSS disabled.

Default voltage/+85 Core Clock/+475 Memory Clock and you should crank out a few extra FPS without putting much strain on your PC.
