Question 14600k power limit values ?

[Blue_moon_7077]

hello

i5 14600kf
asus z790 tuf gaming plus wifi ddr5 bios updated to last version before installing new CPU
lexar ares ddr5 2x16 6400
xigmatek windpower pro Air cooler
rtx 4070 super

i use mainly for gaming

i've set manual voltage to 1.2400v with LLC level 5 that goes down from1.19v to 1.225v under load.
one thing that confusing me . many people suggest that we should set limits according to intel website .. in my case 181w

but i notice my CPU takes 183w under heavy benchmarks it can pull up to 203w only when using prime95 smallftts
my temps are acceptable .so what do you guys think i should set those limits to?

also i have no idea what is the right value for cpu core/cashe limit for my cpu . it was 200A by default. i don't trust this mobo default settings it was frying my cpu with very high voltages up to 1.48v on stock newest bios.

What psu brand are you using, and how many watts does it have altogether ?
Now about for monitoring the psu watts it can have, I personally suggest you let the uefi mobo handle it.
Also the higher your cpu ratio clock speed is, the more voltage it'll need from your psu.

I highly suggest you set a nice comfortable cpu clock speed of 3.6ghz as default. :/
Then you let it auto over clock itself to a comfortable 4.7ghz when it really needs the power for ultra settings in game.

You don't need 5.3ghz of speed like this, especially on air cooler where you will change that thermal grease every 4-6 months.
"you won't like that process, did it with am2+ and up through lga-1150 over the years" -_-
Or you happen to be doing media/youtube/video wor, etck in the middle of the day/night.
This way your system will rely far less on power consumption every day.

With a good AIO cooler you can set both turbo power limits to Unlimited, 4095.

With your air cooler, you can set the turbo power limits to 200W. Your CPU might get hot and trigger thermal throttling at this power level before it ever triggers power limit throttling. The type of throttling does not really matter. Either one will slow down your CPU. I set PL1 and PL2 to 300W.

default settings it was frying my cpu

I am not sure why everyone recommends Default settings. This always sets the CPU voltage way higher than it needs to be set. Undervolting your CPU was a wise choice. It should live a much longer life. The current limits are not that important compared to reducing the voltage which you have already done. If your CPU EDP throttles during any stress test, I would increase the current limits.

I prefer enabling the Unlimited IccMax setting. This usually sets IccMax to the max, 511.75, for both the P core and P cache.

man this intel default settings was driving me crazy you can tune it all day and you will never get good results . i tried to switch to Asus default OC profile. didn't touch it before assumed it will overclock the cpu or something . i changed to it and all weird stuff is fixed for me.


no more VID up to 1.5v. not have to set at fixed voltage all the time. with +0.00500 offset i get the voltages i want with low idle vcore. before i could do -0850 offset LLC level 3 and still reaching 1.3v in games with low clock speeds. 55c !

no more aggressive underclock under benchmarks while you look at temps and think what the hell is wrong with my temps to cause this underclock.

i ended up setting at 200A AND 181W
i can get stable 5.3 ghz under any load with 250A but with higher temps is not worth it . with 200A it will do from 5.3 to 5.0 depending on the load or game. no frame loss i tested both 200A and 250A in different games. higher scores in benchmarks for sure but in games not even 1fps difference.

on intel default clocks would go down to 4.7ghz and 3600 for e cores or even lower for no reason. was driving me crazy

i have old xfx 650w . still working ok. i have set 181w limit and 200A which is the sweet spot for cooling and performance.
i only can play for 3hrs a day max cause of children and work. most games will not exceed 70c .
