Ive read a bunch of guides around overlocking/undervolting the 14900ks, but there are 3 settings I'm still confused if they should be on or off for best performance, and how they effect overclocking.

1) Enhanced Turbo - should this be on or off?
- Default appears to be on. Ive seen several people leave it alone and a few turn it off,
2) Intel Speed Shift - should this be on or off
- Default appears to be on. Ive only seen it discussed like once, but didnt say whether to keep it on or off
3) C-State - should this be on or off
- Default appears to be on. Ive seen about half say turn off, and half say leave it alone.
4) CPU Switching Freq - Keep on auto or set value, 500, 600, 700, 800?
- Ive seen a few comment places that a value between 600-800 can improve performance, but with no real support on what it does.
5) Turbo Boost Max Tech 3.0 - does disabling this improve performance with overclocking?
- i understand it try to push certain workloads to specific cores, which is suppose to improve performance, but if we are running all core at 57 or 58x should this be turned off?

My goal is to get max performance out of the 14900ks at 58x.
* im currently at 57x with the following results
-----Intel XTU benchmark : 14200
-----Cinebench R23 : 41200
-----Time Spy CPU Test : 23500
***100% load temp of 89c***

Thanks in advance

how the hell do you guys boost to 5,6+ ghz during cinebench? I get stuck on 5,3. I don't get how it works at all, because I get the same scores as you do

spent the day swapping between windows versions.

21h2 saw a top score of 43150
24h2 saw a top score of 42550.
- so 600 point diff between current build of win 11 and the glory performance version.

So the rumors are true. There has been a steady decline in Windows performance. Apparently, Arrow Lake performance really takes a nosedive with 24H2. Hopefully, if/when they fix Arrow Lake performance, all other generations will benefit. That’s what happened with the recent Ryzen 9000 launch tweaks.

Hey, when you‘re ready, it would be nice to see all three panels of HWInfo open when R23 is running (about a mid-run snapshot with PRTSCRN would be nice). We all want to see how things turned out after your tuning endeavors. If you can list your key settings at the same time, that would be extra useful! In the meantime, keep up the good work. Thanks to Arrow Lake, Raptor Lake just got a second life!

and thats after i did a regedit on 24h2. there is a drag and drop feature that was eating another 1000 points. otherwise the difference would be at least 1600.

That's just crazy! And now we have that new RECALL feature coming at us that no one asked for. I wonder what impact that's going to have.

I am in a thread about that on OCN, but have not loaded up a 24H2 install yet, to try it out.

I found that 21H2 and 23H2 are a couple hundred points apart in TimeSpy CPU. I will do a CB R23 run in both to see what happens.

I managed a 43k on the most recent version of windows. 24h2. so im done tweaking.

Hi, I apologize for my language, I use a translator.
I have an MSI Z790 Carbon and 14900KS, an Arctik Freezer 3 420.
It was possible to gain a little more than 40,000 in R23. Could you share the BIOS settings?

I wouldnt put in too much effort to reach more than 40.000 score. I end up with 39500, 41000 is a 3,7% increase, just in benchmark results. You will in no way experience this in real world tasks or gaming.

It's a fun game to go for that high benchmark score, but unless you have direct-die cooling (As Arctucas has), I wouldnt go for that much more. You might go from 40 to 42000 score, but for what purpose?

That said: lower the LLC so it will use more voltage under load (if CEP is enabled, make sure the AC and DC load lines are within the margin of error). The CPU will clock higher with more voltage and power limits (you might want to set it to 300 instead of 253), so with less vdroop, it can push out more performance.

@Scuzzmuffin has a good CPU, mine is just average.

"Average". I have an "Average" 14900K, you have an "Above Average" 14900k. To say that these processors are average shows how far we push these things :p

You're right about CB23 needing voltage, I lower it to the lowest stable voltage, if I raise it a bit, my frequency goes higher. Maybe thats why I end up using 5,3ghz, because the voltage is "too low". Still, it will make it up in amps to get the same load power draw, it will reach nearly the same scores.
