I'm want to learn a little about overclocking with this 3800X before I upgrade. I intend to reallocate this 3800X to a daily, non gaming rig, when I get rolling.

Recently ran CB20 MT and all my cores were at 4150MHz, Temps ~ 74*C, PPT 74% of 142w, CPU Power 86w, SOC power 9.5w, TDC 69%, EDC 75%. Score 4955

ST I'm getting boots of 4450MHz

Gaming, using Ryzen Master Histogram I get 1 core that bounces to 4GHz randomly, and the rest are well below 3.8GHz


So just change the CPU Clock Ratio? e.g. 43, and then raise the CPU Vcore? e.g. 1.3v

PBO is confusing for me.

Thanks, but I'm not getting a 6 core cpu.

Feels to me like there's only 3 options:

5600 - $50/core
5900 - $45.75/core
5950 - $50/core

The 5800 is a horrible value at 56.25/core, 23% higher priced than the 5900.
If you insist on spending that much, why not get a lot more for your money?

I don't want a 6 core for a gaming rig, even though it's competitive with highly tuned memory, even while having a nicely tuned memory kit that I could use with it. And I don't want a split CCD 5x series chip right now, before I buy a 5950X, later on down the road. My next step as of this morning is the 6800XT

Your really determined to do this?
I suggest watching this:

---------------------

ok. Please be aware its been like 5+ years since I overclocked a CPU. GPU*s on the other hand different story.

Ram XMP is a form of overclocking, although not many people consider it to be overclocking these days. All gain, easy, and no real risk. Your cpu's infinity fabric runs at ram speed, so it is generally going to show speed improvements on Ryzen right to 3600 if I remember right. If your not running XMP do it and take the free gift.


so cpu overclocking:
So, typically, on most boards, when you enable overclocking and setting the cpu multiplier, you automatically disable turbo and are setting the all core clock.

There are lots of over clocking loops, here is the one I use:
I go on google, punch the cpu number in along with the word "overclock". I then see what other people are getting, and what voltage they are using.
I will then set the voltage to whatever comfortable with
and crank the cores up to max cpu rated for
stress test it (I used to use prime95), check the temps, and see if it crashes
-> if it does not crash, up the frequency and try again
-> if it does crash, and temps are ok, up the voltage and try again

after repeating the loop a bunch of times you will eventually find a threshold of temperature, frequency, voltage, and stability your comfortable with. It is not my fault if you fry your cpu like an egg, or pop a mainboard vrm.

20 years ago a person could get 20% more performance out of it. In the heyday we had Celerons outperforming Intel's best stock Pentiums. These days, your very lucky if you get 3%. Most people get nothing.

---------------------

*why not do your GPU instead? My Vega 56 pulled 6% more performance out of no where. If you purchased your GPU late in the product life cycle**, they typically can overclock for a lot more gain then a CPU will get you.

**products purchased early in the life cycle typically overclock poorly. The get binned by how well they perform. However, as the manufacturer runs the line, they tweak it to get better yields. This tweaking means later revisions of the same model part tend to have considerably more overclocking headroom. Late product lifecycle also typically has high end parts being relabeled as low end parts to fill demand. These late product lifecycle "low end parts" quite frequently can get results from overclocking and or a re-flash.


Is this also true for threadrippers with good cooling? I remember you can get decent gains out of overclocking them if you do it right
