Getting Less MultiCore Ghz on i5 13400F

[iameatingjam]

Hi, What is AC/DC? And yeah 80c Max under Load, Idle is 39c.
I clean my PC every Week it's like my baby xD

one thing that confuses me is that if my CPU is only Pulling 100W and doing the Maximum Ghz that it can, why should I Put PL1 on 148? When 100w is giving me 4.1Ghz.

About ac/dc, you don't have to worry about it if you don't want to, just a way to tune the voltage the cpu requests.

I just took 148w from the intel spec sheet. Sounds like there's something else preventing you from pulling it anyway (could be a current limit). So if set it at 148, even if you're not pulling that, at least you're bumping into one limit, and not two. Bumping into those limits can cause a performance penalty sometimes. But it doesn't really matter. Set it to 100W if it makes you feel better.

I'm just wondering what more than 100W can do with my CPU because the max Ghz on the P cores are 4.1Ghz and I'm getting them with 100W, So what is 148W gonna do? just more power but no performance? or can I make my CPU to be on 4.6Ghz on all P Cores? or 4.4Ghz

Okay hmm if its not thermal throttling and not drawing all its allotted watts... its possible your motherboard has multiple power plugs and only one of them is plugged in. My mobo has I believe a 8 and a 4 pin plug for cpu power. Technically I could plug in one or the other and the computer would still work, but I wouldn't be able to get as much power. So thats a possibility. I looked at pics of your mobo and I can confirm there are two plugs at least. I think even a 4 pin should provide enough but if you have the appropriate plug, why not plug it in?

Other possibility, its a current limit. Look for something called iccmax in your mobo and increase it... SLOWLY. I think I might have killed my last cpu with too much current because my mobo was blasting 511 even on a conservative power profile which turns out to be about double what it should have been at ( though intel was kinda encouraging stupid behaviour like that at the time to be the chart topper). I now use 307. and thats for 253 watts. As for how many amps create how many watts, depends on the voltage as far as I understand. And that is usually set up to be dynamic. So I don't know what to say other than increase it slowly until you get the result you want.

Hi, My current auto setting is on 511A too, should I be worried?
btw I have Asus Prime Z790 D4. Where is the detail about this in the spec sheet? because I don't think I missed something to plug in.

Hi, My current auto setting is on 511A too.

.... Really?

Do you not have an intel profile set? Cause an intel profile should not set it that high. Its possible its just ignoring that setting. I would use Hwinfo to check what your Iccmax actually is. And go from there.

Edit: Guess I should give you some instruction.

Open hwinfo, go to summary > central processors > select your cpu. then look to the right and it should be there under iccmax ( might have to scroll down a bit)

Hi, yeah it was like this from the beginning and yes I'm on Intel profile.
i have a locked version CPU I don't think that should be a problem.
how can I see my ICCMax on hwInfo?

I edited my above post with more specifics.

HI,
yeah, it's 511.75A.
how much should I put? it' on Auto in Bios.

Sorry I really don't understand whats going on here. It doesn't make any sense to me. You both have an intel profile on, have a 511 iccmax which intel wouldn't do, and you still cant even get your chip to draw over 100w, even though you have an 8 pin and a 4 pin power cables connected ( I think thats what i saw from the picture - it was kind of obstruted).

There's some really smart people on this forum I bet somebody else will know.... guys?

it's making me so confused too.
if it's drawing 100W, then how it can perform on max clock speeds? and if it is, what's the purpose of the other 48W? ;D

2- yes I set the intel profile in my motherboard but it's 511A ICCMax, which is bad right? And what value should I put?

3- Both the 8-pin and the 4-pin Connector are Plugged in.

I'll Update the Post in a few minutes let me just double-check my cables

Update: yes the 4Pin is Plugged in As well

Well I can answer that one at least. Your cores don't necessarily need their max power to reach their max frequency, it all depends on the type of load they are under. A core could be at its max frequency and using only a couple watts if its not doing anything... which actually gets me thinking.... I don't know much about Aida ( Don't use it) but I had thought it was rather intensive.

But just to be sure, can you try downloading cinebench r23 (or any version really?) that will hammer every single thread and should get max power draw out of it. Try that, see if you get max power draw, if you do, then yes reduce iccmax to something like idk 200. And then see if you still get max power draw.
