I have an i5 11400f and a Nzxt N7 Z590 motherboard with latest bios and 32gb 4000mhz cl 18 ram

In this video it is suggested to raise the Base Frequecy Boost from 65 watts to 125 watts for a higher cb r23 score, I also do that even though I don't have Base Frequecy Boost but raise the tdp, Long Duration Power Limit from 65 to 125 watts

What then happens when I stress test is that I get around 3,900 mhz in aida64 with everything activated, instead of stock 65 watts where it runs around 3,100 mhz and in other tests 4,200 mhz with Long Duration Power Limit of 125 watts.

The problem is that something goes down during the aida64 test after max 2 min, which is the cpu (it doesn't freeze, not even bsod) the test stops and the aida64 turns completely red, back to 65 watts then the test is100% stable but for a lower score than It ca can be in cb r23, which I have just under 10000 in multicore (higher in the video) as it does not boost all the way up to 4,200mhz as the bus speed is not quite 100.

How can I get it to run completely stable with tdp, Long Duration Power Limit of 125 watts?

Hey there,

Well, you can try Throttlestop. Install it, and run it. Once it's running open the 'Limits' tab, and also the built in bench, TS Bench. Run the bench and look at the limits screen, if it is lighting up in red or yellow, it may mean you have some sort of throttling going on.

There are many options in TS Bench that may work with your CPU. It's also a very good way to set voltages etc. PL1, PL2, Tau.

You could try a vcore offset (as in a '-' minus number). So lets say your vcore is running at 1.37v. You can use an offset of 0.05mv which can help instability.
 
Thought it was my cpu, but could be my ram g skill ripjaws 4000mhz cl 18

It's unstable with the ram at 4000mhz, stock seem much more stable

PL1 red, a few sec befor the 960m test is over PL1 was yellow

Enable,use Load line calibration + raising power limit ?

What speed is default for those dimms (when stable) normally it's 2133mhz. That is not good. See how that goes.

Maybe enter timings and voltage for ram manually and start lower on the speed, say 3600.

LLC is for incresing CPU stability. It's really meant for CPU OC'ing. It can overvolt the CPU, so I would not use more than the frsit or second option. Anything higher will cause other issues. In fact,. I'd leave that alone for now.
 
2133mhz, it does also throttle at stock ram speed, when raising power limit in intel xtu it is stable with ram at 2133mhz i just don't know why hwinfo64 is showing stock value of 65 and 154 watt pl 1 and pl 2

Update i did try AVX-512 in intel xtu (intel extreme Tuning Utility), Current EDP Limit Throttle

I do get a power and current limit, both power cables for my cpu is connected

As soon as you increase frequency a RAM overclock can become unstable. 32gb 4000mhz cl 18 ram is not a simple overclock if 4xDIMMs. You need is start with the cores/cache and then RAM. With 4xDIMMs its easier to hit DDR4-3600. Above that frequency you start to need to know what you are doing to get stable.

So overclock your cpu first and then move onto the RAM.

So set the RAM to something low and stable. Like the default for the cpu. Then go to you on the cores/cache. Then move onto the RAM. I have found that settings at lower frequencies for the cpu are fine, with a RAM overclock. The second I push the frequency to the maximum vccio becomes unstable. So when I run large ffts I get errors.

At some point vccio has to be perfect on my cpu. Also this then allows you to dial-in a lower vccsa.

For the 10900k I found a vccio of 1.16volts and a vccsa of 1.24 volts. This is for 5.2GHz SSE and 5.1GHz AVX. The RAM is 32GB DDR4-3600 4xDIMMs, overclocked to DDR4-4000 CL15 @ 1.5volts with extremely low timings.

You have to do it one part at a times. Then test and then move onto the next part.

Anyway stock settings, a power draw boost should be stable. Also if you are going to overclock the RAM or CPU. Make sure you understand would the safe voltage are. BIOS's love to put insanely high voltage into the CPU for memory overclocks.

Note that overclocking requires good cooling and a decent PSU. If heat builds up in your case the memory can overheat and your system can become unstable. This happens all the time with extreme memory overclocking. Some RAM settings are affected by temperature. Don't go mad into the timing beyond the primaries unless you do your homework first. Trust me.

I have 3200mhz cl16 trident z rgb ram (disabled the rgb) was what i could get with delivery next day and on the qvl list in the 2x8gb version (mine is 2x16gb).

Have thought about the 11600k or kf since it alows me to oc much more or less, not just use what is stock, mabye better pinned cpu, so fare my 11400f is down by 0.300mw
 
I find its better to just read reviews about the cooler before I buy it. I got an 360 rad because the 10900k draws over 350 watts in prime95 small ffts once overclocked.

If the TDP is under 200 watts and the cooler is 200 watts hopefully all will be fine.
 
Update: higher power limits is essential for unlocking all the power my 11400f has

It just gets super hot with higher power limit

First i did was bying a bigger cooler Cooler Master ML240 ILLUSION i could get one for under 100 euros with shipping

Here is a review (11600k) https://www.funkykit.com/reviews/co...terliquid-ml240-illusion-cpu-cooler-review/5/

My cpu is stock slow, mabye 1ghz 1000mhz slower in some situations compared to 4.2ghz 4200mhz with higher power limit, i alos bought a 11600k BECAUSE it's alo a hot cpu but not much more stock then my 11400f with higher power limit BUT it boost to 4.6ghz stock, right ?

Intel Core i5-11600K Review - Impressive Value

The Core i5-11600K is Intel's mid-range entry using the Rocket Lake architecture. Our review confirms that it is a great alternative to AMD's overpriced Ryzen 5 5600X, offering similar performance at almost $100 less. The i5-11660K is also fast enough to compete with last generation's 8-core...

Lower vcore and a bigger cooler would be enough for a stock 11600k which is much faster then a stock 11400f, as mentioned many times and now, a 11400f with high power limit is hot

These cpus get very hot the more you push them. ALso the frequencies are about 200MHz less in overclock than the 10th gen. The stuff I posted above you tell you what you need to know and cover if it is worth it overclocking. Manual vs. normal boost in games. Watch the video were he got next to nothing in games.

Good cooling will help these CPU but they don't overclock as well as 10th gen.

The 11900k despite having 8 cores it's faster then a 10900k with 10 core and 11gen have pci e 4.0 as the first main stream intel cpu and ipc is better

From 11gen they got hot

For max power (high power limit) you need a 240 mm aio or bigger with 11 gen

They just don't go as high frequency wise. I had the choice to get a 10900k or a 11900k. Got the 10900k. Yes the 10900k is PCIe 3 and the 11900k is PCIe 4.
 
11 gen is just better it's not like an i7 4770k vs 4790k or i7 6700k vs 7700k where they basically performe the same within the margin of error

Max ghz isn't important, what is importeten is it runs stable and high enough for everything to run smooth when gaming

The 11900k is faster single core but slower multi-core than the 10900k.


Intel-Core-i9-11900K-8-Core-Rocket-Lake-vs-Core-i9-10900K-10-Core-Comet-Lake-CPU-_-5.2-GHz-Overclock-_-3DMark.jpg


For you the 10600k and 11600k both have the same core count. Thus, I would go with the 11600k.

In games it can be kind of close.


The main thing about the 10900k is the increased frequency. I lost the silicon lottery, just about got 5.2GHz.

Here a 10900k destroys a 11900k. The 10900k hit 5.4GHz which is a very high overclock.

Conclusion​

As seen from the FPS data for 1080p High and 3440x1440 High, the 10900K comes ontop in every title.
The lack of cores, lack of L3 cache and higher RAM latency leads to disappointing performance from the 11900K, with the last 2 hurting performance specifically in gaming.
Based on these results, Rocketlake should definitely be skipped and I would not recommend 11th generation Intel to anyone who wants the best gaming performance. The 10900K would win in multicore performance too and hence be better for productivity. The only use I can see for 11th generation CPUs would be workloads that utilise AVX512 instructions, which is currently a very small number of software. Other than that, it is also enjoyable to overclock RAM on Rocketlake with a vastly different experience to the Skylake architecture.

The 11900k had hyperthreading disabled so it could hit 5.2GHz. The 10900k is just not worth upgrading to a 11900k.

This is the tomshardware review, a 10600k @5.1GHz will beat a 11600k stock in games. At 1080p the 11900k is just ahead of the 10900k which is overclocked lower. The 11900k is 5.2GHz and the 10900k is 5.1GHz. Kind of best 11900k vs. a not so good 10900k.

My goal was to get away from amd since it was a little unstable with bsod reboots https://community.amd.com/t5/proces...ze-scep-certificationregistration/td-p/495156, faulty top m.2 slot, white flashes on part of my screens,gpu crashing All gone now

11400f need to have high power limit or else in my pc it won't have close to max perfomance 3.0ghz stock instead of 4.2ghz, it get's hot

Stock 11600k it boost higher, it boost to what it should 4.6 and max 4.9ghz but most important my 120mm aio can easily keep it under 100 c since it runs almost stock but still runs hot in the most demanding tests

Personally i don't care if my cpu can do 5.0ghz or since it matches my rx 6700 xt pretty good
