Hi All,

So I have hit a brick wall with my OC.

5.1GHZ on 10 cores

5.5GHZ on 5 cores

5.4GHZ on 6 cores

No Avx offset.

LLC 6 @ 1.375V.

XMPII 3200MHZ.

I can boot up on 5.2GHZ no AVX, and even start on cinebench however instantly hits 100 so it needs to be delided to have any chance. Is it worth delidding?

I have a manual stable OC in Manual Mode @ 1.420 Vcore in bios. Idle load voltage is 1.40, under cinebench load 1.250v. All temps are fine, see attached image. I have a 5.2GHZ Overclock with 0 AVX. 53GHZ on 4 core load LLC 4 Cache 4.8GHZ I cannot for the life of me just enter 1.420 in Adaptive with 0 Turbo boost Offset. As soon as it try to load windows with Adaptive @ 1.420, when I reach the circular boot loading screen it freezes. I have changed LLC all the way upto 7 and still I have no luck. WHAT IS GOING ON. I have been at it for hours
The only way I can actually use my setup is by loading on Manual. I don't know how to use Offset.

5.5 Ghz on a 10900k. Is that possible on all cores?
Click to expand...

Yes mate. I just set it by core count. 5.5GHZ on 6 cores 5.4GHZ on 7 Cores and 5.3GHZ no AVX on 10 Cores. Vcore in bios set to Adaptive 1.28V, Under load 1.32V Die sense LLC 3

Recorded it.


Ignore cinebench score, its low because I'm recording at the same time

So correct me if I'm wrong you might as well have set an all core of 5.3ghz as there will be virtually no scenario that will boost the cpu to 5.5 ghz.


Also your Vid is CRAZY high.

Cinebench single score seems to hold my CPU @ 5.5GHZ - 5.4GHZ. If i'm in Microsoft office, windows teams, web browsing I'm constantly hitting 5.5GHZ

Also VID is fine, it's not the voltage that its actually getting. it can "ask" 1.7V but will never actually get 1.7V. My vcore does hit 1.5v for a split second when there is no load on the CPU. This is just the nature of adaptive voltage though. I'm led to believe VID is what the cpu requests based on a voltage table set from intel. My vid is crazy high even if I set my cpu on stock.

Also this is the highest R23 I have got.

So it says the maximum is 8 cores and 16 threads for 11th Gen Intel CPUs.

The flagship, the Core i9-11900K has eight cores and 16 threads. Base clock of 3.5 GHz with 5.3GHz Bost clock (usually on one core only). So likely 4.7GHz across all cores.

You reckon you can overclock all cores to 5GHz?

It should be able to hit 5GHZ I reckon. The issue they are having with the 10nm stuff is that they are not able to achieve high clocks. However, the 11th gen is a backport of the 10nm so it is still on the 14nm which should enable it to OC just fine.

I have a 10850k, It clocks just fine but the temps are holding me back a little I'm at 5ghz all core at 1.31v core LL6, i have a full loop with 2x 360's in push pull. My 3080 is liquid metal and that brought temps down from 55 degrees to 40 degrees but I'm hesitant to do the cpu as the last cpu i did was a 5960x and it alloyed with the heat spreader to the point I had to lap it.

I dont really care if I need to lap it in the end. It is staying in my system for a good 5+ years. After that it will not be worth too much anyway. Plus the performance advantage it will give far outweighs the disadvantage especially if yours is a good overclocker. I have liquid metal cooled my GPU too. Love the liquid metal.

Btw I'm so close to hitting 18000 points but I dont think its actually possible lol. I upped by cache to 50 and I'm so close.

Some of those temps are really low, are you chilling the water ? ;)

Check these temps out... and finally hit 18k!! wooho. I'm running Liquid metal on the IHS with a H150i Pro GTX mate. I have to admit though, I did open the window today with that last run. Other runs, i just set the pump to maximum and fans maximum. Temp in my room is usually 18-19. I'm still impressed with the corsair AIO.

Opened the window ???? where do you live ? Siberia ?

9 degrees on some of the cores , that's like an ambient of 6-7 degrees (depending on fan output). That's crazy.

My room right now is 22 degrees , my water temp taken from mid loop is 25.8 degrees , that's on a Alphacool xt45 360 cross flow and an EK XE360 60mm rad all with push pull ML120 pros. (running approx 10% power at those temps and ramping up to 75% output to maintain loop temps under 35 degrees but never sees higher than 32)

At 100% fan output I can roughly match ambient temperature so as we speak I'm at 22 degrees water temp and 22 degrees ambient. (however I think I'm going to go deaf)

Haha, check out the picture here. So all I would do is open the window and turn my case around so the intake is facing my window. It was very cool last night so that's why. Also I had power setting set to Balanced. The cores would only hit 9 when they go all the way down to 800MHZ.

I also genuinely put my performance of the CPU down to my motherboard or at least a big portion of my achievable clocks at least.



To show I have nothing exotic going on...



Try liquid metal on your IHS and then watch your temps drop like crazy. I either got lucky with my CPU that it likes to overclock or Asus SP numbers are pulled out of their arse sometimes. My CPU is showing up as 63. If I revert back my Bios it shoots up to 112. Your guess is as good as mine on which to believe.
