Intel 11 gen not stable with Long Duration Power Limit set to 125watt

[Dr. Dro]

stock it won't boost as high as it can because of the power limit

Unlocking the power limit is going to reduce your processor's operating frequency because cooling is inadequate. And read W1zzard's review that you linked: he says everything.

1. Processor is not overclockable
2. BCLK limit is 102.9 MHz and this comes with a slew of problems of its own (frankly not worth it)
3. Power limit can be raised but it will not exceed turbo defined values, and cooling requirements will increase

We've told you this, if you insist, then there is no point in continuing this conversation any further. If you want more performance, you will have to purchase a i7-11700K or i9-11900K processor. Otherwise, just enjoy what you have, man. No point being obsessed over it, it's a locked Core i5 and it does its job the way it has to.

Mind you, the power limit mechanics apply even to unlocked CPUs, I own a i9-13900KS personally, and even this CPU (if not particularly so, because it's the absolute fastest and most aggressive clocking of all Intel CPUs) is subject to it, if I raise its power limit beyond what my cooling can handle, it will throttle and average clocks will be reduced to a point where I am actually losing performance. With my 360mm AIO liquid cooling, the sweet spot that prevents thermal throttling turns out to be precisely the 288W/no time limit setting that my motherboard offers.

Multicore only get's higher if i raise the power limit (and what is related to edc) ,temps won't matter since the power limit is reached long time before temps are a problem when the cpu runs stock, if tems are 60c and tdp junction is 100c it won't go higher since power limits say 65 watt and 154 watt, it's the 65 watt that won't make it go to 4,2ghz on all core when gaming when wanting to make shure background tasks has as much power (mhz) as possible

That's why in the video multicore is higher setting it to 125 watt and some games according to powertechup get's higher fps when removing power limit

Throttle stop detects power limit, thats why it's boosting on all cores lower on all threads compared to removing pl or setting it higher

Im only throtteling when i use all settings in aida64, that test is extreme with high power limits

Then just stop aida stresstesting?...

3. Power limit can be raised but it will not exceed turbo defined values, and cooling requirements will increase

I never said that, it is just boosting higher on all threads in avarage or higher on the last 3-4 threads then stock. CB R23 is higher in multicore

Stock i get power limits mabye also edc limits (throttle stop)

Then just stop aida stresstesting?...

On less your doing something special you won't get 100% load on the cpu,gpu,ram and ssd

The aida64 is worst case senario and i can add gpu load,heat to the test without having some graphical going on in the background as you do with benchmarks like 3dmark or heaven benchmark

stock setting

Optimized,tuned

Tell me why i should run my cpu stock ?

I do get power limit and cpu throttling using fpu and cache, if it happens speed goes under 4000mhz

Increasing the turbo power limits allows the CPU to run indefinitely at its full rated speed which I believe is 4200 MHz for the 11400F. If you do not increase the turbo power limits, this CPU will struggle to run fully loaded at 3000 MHz. Increasing the power limits is a no brainer. For maximum performance, it is a must.

Turbo boost on 11400f

I've been thinking about getting an intel 11400f but i dont completely understand unlocking power limits and turbo boost. I need to turbo boost it and increase the power limit so i can get better performance out of the more cpu demanding games. Is it safe to turbo boost it and have it stay at tur...

The answer is undervolt to get the most out of the 65w limit, already said, you just fail to understand this

 

[gasolin]

why would i undervolt it when it needs alot more current to run at 4.200mhz most of the time ?

If i do undervolt i get power limit and mabye also current limit, sort of get that stock

For some reason i also focus on not being power limit and edc,current limit since i started to use throttlestop

 

[AusWolf]

And it's overclockable , unlocked multipliers, and you can configure to run max boost speed on all cores, holds better resale value, imo just the better option.

No need. My 11700 beautifully holds 4.4 GHz all-core... with the proper cooling of course.

I don't see anything wrong in these screenshots. What exactly is the problem?

When a PL-unlocked Rocket Lake CPU fails, it's either the motherboard's VRM or the cooling giving up on it. Delivering 150+ Watts, cooling it, and maintaining stability isn't easy.

 

[gasolin]

Performance is low, it just don't use setting (unless you change it manually) for max perfoamnce, it should boost to 4.2ghz in benchmarks stock, but it doesn't, it just about reached 3.0ghz stock about 30% higher performance when rasing power limit

 

[P4-630]

No need. My 11700 beautifully holds 4.4 GHz all-core... with the proper cooling of course.

I wasn't quoting you.

 

[AusWolf]

I wasn't quoting you.

I know. I just pointed out that power limit tuning a non-K CPU isn't as stupid as it seems for avid K-series buyers. All you lose compared to a K unit is a couple hundred MHz.

You still need a decent motherboard and CPU cooler, though.

Well, 125 W isn't the top for Rocket Lake. My 11700 consumes around 160-170 W in Cinebench at 4.4 GHz, or clocks down to 2.8 GHz with the factory 65 W limit. 3 GHz stock sounds reasonable.

 

[gasolin]

3ghz when it can do 4.2ghz on all cores ?

 

[AusWolf]

3ghz when it can do 4.2ghz on all cores ?

It can, but not with factory power limits.

Edit: Either you don't understand what power limits and turbo clocks mean on Rocket Lake, or I don't understand what you want.

 

[gasolin]

It really didn't do 4.2ghz untill i raised power limit

I don't think the 65 watt long term power limit wouldn't make it run at 4.2 ghz playing games and if i had to have power limit, undervolting might not gi me more power when gaming

Not shure it can do 65 watt and 4.2ghz doing gaming as it did with higher power limits

I did have to give it higher limits so i don't have power limits, again i used throttlestop , using it to set minimum power and edc,current limits

So let's make it clear: Rocket Lake will never reach its advertised turbo clock speeds at stock power limits.

• If you want a 65 W limit and easy cooling, you'll have to make do with ~3 GHz all-core.
• If you want 4.2 GHz, you'll have to unlock your power limits and slap the biggest cooler you can find on it. Rocket Lake needs anywhere between 140-180 Watts to run its default all-core turbo clock at a 100% load, and the stock power limit prevents that.

You can have either 65 W or 4.2 GHz, not both. This is by design. Savvy?

Shocker, really, who would have thought that the cheapest Rocket Lake CPU would be anything but power efficient when clocks are up? I couldn't have imagined that one. I'm actually particularly amazed by the concept that a CPU that uses more energy dissipates more heat and thus needs better cooling. I couldn't possibly have known that.

That "Cinebench" game looks cool, though. Think it can run on my PC?

why would i undervolt it when it needs alot more current to run at 4.200mhz most of the time ?

We have told you numerous times.

Because your CPU is already running stock and it cannot do any setting other than stock, this is by design. What you're attempting to do is simply trick the turbo boosting mechanism so it runs at the maximum bin all the time. Undervolting helps to that end, but it's not a guaranteed behavior, which is why your processor is not sold as a 4.2 GHz CPU. Furthermore, you have already observed the obvious drawback of raising clocks: power goes up alongside it, and so do cooling requirements. Like I said before, if you want more control over your processor's voltage and frequency curve, even if you do not mean to overclock, you need an unlocked K-series processor.

OP seems to have a 240 mm AIO, which should be enough to just raise power limits with infinite Tau, and call it a day. No undervolting or V-F curve adjusting magic trickery is needed.

From all that was let understood in the thread, cooling was a problem. A 240 mm AIO should be able to run a 11400F in its sleep. Airflow, hot mobo VRM, perhaps? It doesn't make sense to me, I mean, it's a 11400F. It shouldn't be too hard to tame.

Exactly. Post #29 already shows CPU temps in the low 70s at 4.2 GHz, which is fine. So like I said earlier, I don't understand what the problem is.

If I get it right, OP wants to run 4.2 GHz at 65 W, which is never going to happen, nor is it something they should be worrying about.

Now i have a 240mm aio, would have bought a 360 if i had the space for it in the top of my case

It can't if you only have a single fan cooler

in the old day you could just raise the multiplier to the turbo frequency and it would run at that speed on all cores,threads

Today you can't, can't remember if it was cb,aida64 or something like occt that a 11400f only ran 3.0ghz stock, mine wouldn't run 4.2ghz by raisng power limit to 125 watt, some say it would be faster but throttled at most demanding test to under 4.0ghz so it was power limit and edc,current limit

I was feeling i had an i9, so much power did it have to use (and got hot), i also used throttlestop to adjust the power since it didn't was stable at 4.2ghz doing something like gaming and wondred why it didn't stay at 4.2ghz , power, current limit

it can't

I just wanted it to run a 4.2ghz, alot of videos say you have to raise power limit, my combo wasn't enough going to 125 watt, it might have run at 4.2 ghz but after a short time it went under 4.0ghz because of limits, TAU wasn't enough

You know, silicone lottery

70's is without fpu in aida64, fpu adds alot of extra power,load on a cpu

Right, let me simplify it:

Now, choose your power limit to match your motherboard's VRM's and your cooling's capabilities. Got it?

There is no silicon lottery in the whole wide world that will give you 4.2 GHz at 65 W on Rocket Lake. That's just not how it works.
