Question Overclocking

[pcslookout]

Is it worth it nowadays ?



For lets say a lot more performance ? Like it has been in the past.

Only if you enjoy the overclocking process itself. The performance benefit even with crazy cooling and top shelf hardware generally is not that great. It's more of a RAM OC and undervolting game these days. Modern CPU's don't leave much performance on the table. The boost/dynamic voltage algorithms have gotten pretty good and have mostly rendered static OC with fixed vcore obsolete. It's been that way for a while now. I still think its fun to tweak settings and optimize performance though. There are lots of options in a modern UEFI to really dial things in. it just doesn't yield as much extra performance as it did back in the day.

Only if you are the type who wants to squeeze every last drop out of, well, anything

I see it as a hobby. If there are gains, even 1%, heck that's an accomplishment and I'll take it.

In this modern day of factory overclocked CPUs, I guess it would be worth it if yields are so good that some cores of even an i5-14600K hit 6 GHz. One could then peg some ST craving process to such a core for maximum performance.

Some high end CPUs (notably the 7950X3D) can't even be overclocked unless you use dodgy bclk OC methods. For most users it's turn on PBO and forget about it.

If you are really hardcore you can still OC but it is far from being as practical as it was decades ago.

I am playing Diablo 4 on a 8350, GTX780 with 3gb vram, 16GB RAM, and it has been an absolute pleasure to squeeze the performance out of it.

BTW its running 48xx Mhz with 293 FSB and 23XXMhz RAM. SIg rig, blew traces on original CHVFZ with the 8320, that hit 4.9Ghz at 222 FSB.
Bought an OG Titan for the 6GB VRAM since my waterblock fits it, and I have the AC passive backplate, which I am going to order the parts to make it active.

I do want to put a 7900 XTX in the system, but real life won't allow it right now. I think I am getting ps5 performance. For sure better than ps4 cause my son has that in living room. I play at 1440p UW avg 60-100 FPS with high settings, any option that has 5 choices is on the 4th, and the built in scaler to balanced. I don't overflow the VRAM buffer.

Want to try BG3 but xmas is coming and the grandaughters are priority.

You can get good OC out of RAM these days, at least on AM5 platform. Don't know about Intel's side of things, I don't go there.
Like has been mentioned above with PBO, don't just leave it on auto or enabled, of course depending on the motherboard you can tweak this as well but limits to 200MHz boost only.
Fine tuning Curve Optimizer in PBO can be fun & experimental, some chips I've seen can have negative 40 on the curve with the full 200MHz boost! Silicon lottery & sheer skill is the go here if you want to explore.

It varies from CPU to CPU or even generation of CPUs.

Running 5800X3D better and cooler: https://www.resetera.com/threads/ry...mps-less-power-consumption-better-cpu.660658/

Zen 4 running only hotter and not necessarily better with PBO2: https://www.pugetsystems.com/labs/a...ermals-and-content-creation-performance-2373/

From the other thread, I can see that the new threadrippers are good overclockers. So, only if your use case requires a threadripper.

Hmm, I usually buy a cpu and see if I can get a 6-8% performance boost out of it just to experiment, then I set it back to factory defaults. Are you saying that on modern processors, this isn't easily done any more?

Not unless you have serious cooling. Even then, the gains may not be worth the cost or pain of installing that extra cooling capacity (huge heatsinks or AIOs). And the fan noise will be enough to dissuade you from using the overclocked settings for long.

Ah, sounds like it would be better to put the PC itself down in the basement, where it is about 20 degrees cooler. Noise wouldn't be an issue then, if you ran keyboard, mouse & video up from there. Anyone out there do something like this? I imagine that 20 degree cooler air could absorb a while lot more heat energy.
