what's the typical gaming wattage with games that uses alot cpu like miles morales and plagues tale requiem?

I don't have those games. Assassin creed origins will get about 160w maximum.

Found a nice video on undervolting 13th gen: https://www.youtube.com/watch?v=EilwjiqCiSw

However, it involves setting fixed voltages instead of offsets. Something I don't want to do at the moment. Will still stick to -100mv offset for now.

That 13700K with its 253W TDP is gonna be difficult to cool by air especially here in hot & humid Msia. I personally would not recommend it but for last resort, you might want to consider going AIO if you want to fully utilise that CPU capabilities.

Yeah, in the future have to think about bigger casing to start off.

I think my mobo voltage is causing some of the thermal problems.



The voltages for the core ratios looks really wrong. Need to research more on V/F voltages.

Bios allows max -500mv offset which is much better than the -100mv limit for vcore offset. I think this is the key. I didn't have time this morning so I tried the usual -100mv offset for 43x to 54x. Max voltage in windows was 1.406v, same as vcore offset -100mv. The difference is that lower ratios are stock voltage.

In the meantime, anybody can give opinion or tips for correct voltages on this?

Edit : On skatterbench YouTube video, their reference range is as below:



Vf point 1 to 4 is similar to mine. The rest of my vf voltages are just too ridiculous. Looks like my challenge is not so much undervolting the 13700k, it is actually correcting the VF curve first then undervolting. My VF curve is not a curve at all. More like a steep cliff! Lol.

maybe just go easy route and use fixed voltage. if the cpu don't have load it won't have high idle power consumption anyways. my 8700k 1.23v 4.7ghz even at 10-15% usage it uses like 30+watts, and way lower when no load

My main issue is the boosted frequency and voltages. I think my mobo is setting too high a voltage at 43x - 54x. I am getting a clearer understand of VF curves on YouTube and if my mobo readings are correct, my VF curves is definitely not correct. Now my only headache is to find some norm VF ranges for 13700k so that i can try to set mine. Most vf ranges on the Internet is mostly 13900k or alder lake.

After work will try out some VF offset and see how it goes.

now i feel gatal to get 13400f and msi b660/b760, nice cpu upgrade and cheap enough to sell easily when intel new socket cpu comes out

nvm saw 13600k tests, it doesn't consume that much power at full load, so easy to run on b760 motherboards

I not 100% sure if this is anything related but I notice you using Z690 Phantom Gaming mobo. That thing has only 9 VRM phases so perhaps it might be a tad too underwhelming for ur 13700k. It might be throwing in lotsa voltages just to keep that CPU within its performance settings. This could also be one of the reason ur getting loads more heat coming out.

EDIT: After searching in Asrock site, that mobo is like possibly the worst Asrock Z690 you could buy as even their maligned Pro RS mobo has 13 VRM phases. I beginning to suspect its ur mobo thats the weakest link.

Yeah... I should have just gone for a better mobo which is only like rm300-400 more.

I tried to tweak the VF curve in bios but it was buggy. Some research on the Internet do mention about buggy bios and buggy VF curves. Scatterbench mentioned about only setting one point of vf curve on each boot up for it to work. Meaning i need to boot up at least 5 times to set VF 7 to 11. And that is if that voltage offsets were stable. Too much hassle.

I finally tried fixed vcore voltages of 1.28v. That helped with no more voltage spikes but the cpu will be constantly at 1.28v even at idle so no.... not acceptable for me either.

I have a few other things to try out, including disabling intel turbo boost 3.0. Thermal frame, probably not yet as I read that they are mainly for alderlake although supposely can be used for raptor lake. Going to wait and see whether there is a proper thermal frame for raptor lake.

Long-term wise, maybe no choice but to get a bigger casing to fit an AIO 280 or 360.

Anyway, trying to tame this hot 13700k beast has brought back fond memories of tinkering with computers and somewhat renewed my passion on computers. I thought I was way past all this.

Ok, after tweaking whatever I can, I managed to get the temps down.

Looks like my cheapo mobo was just feeding the 13700k with too much voltage. It even had a "Core voltage boost" that cannot be disabled. I just had to set it to the lowest setting.

Vcore offset -100mv sometimes work sometimes doesn't. I think I solved it by setting the offset in 2 different bios menus.

Loadline calibration had to set to the weakest level so that there was more vdroop.

All-in-all, managed to drop vcore voltages about 0.1v during assassin creed origins. Temperature dropped to around 65-70'c instead of 75-85'c. This is with the fans tuned down more than before, no need to be in power saving mode, and all turbo boost turned on. PL2 set back to 253w. Other games also showing better temps.

The only sad thing is I cannot set the V/F curve as that would have helped a lot. Vcore offset sets all the ratios but VF curve can set higher ratios to lower voltages. Bios settings just doesn't work and Intel XTU doesn't show the VF curve tab at all. Not sure why. Cheap mobo maybe....

Anyway, quite happy with the results. If I am ambitious, I might try to drop the vcore offset a bit more but I read it is difficult to get -150mv unless you are lucky. Idle vcore is already like 0.648v. VF curve is the way to go.

AFAIK some (or most) Z mobo will behave differently when drop in a K sku CPU and will default to different setup, ie PL1 & PL2 becomes unlimited. Problem is ur Asrock mobo VRM is underspec and is dumping loads of voltages & heat out just to run that CPU unlimited. Compounding with a insufficient cooler, ur system is more efficient as a spaceheater than running at its full potential. I'm afraid to say but I reckon its better to change that mobo to something better, MSI Z690 Pro-A is probably the cheapest decent one but mostly are DDR4.

Another you could consider if you can stump more money (and selling that Asrock mobo) is this Asus Strix Z690 https://shopee.com.my/-ASUS-ROG-STRIX-Z690-...4e-1a87517e6390
it is a MATX tho

Giga Aorus Z690 looks quite good as well

If ur a bit more adventurous you could also put in Thermalright's anti bend frame.

I had already set PL1 to 125w and PL2 to a lowered 200w initially. However, with the more acceptable temperatures, I can set PL2 to 253w again.

And after more googling today, realized that for raptor lake, PL1 = PL2 = 253w! Going to set my PL1 to 200w so that it is lower than my cooler tdp of 220w.

But yeah, the gigabyte aorus looks tempting. And price difference not that much from mine. The asus mobo, wow the price! But my cheapo mobo not cheap to begin with. Will just stick to this mobo for now. Quite happy with the temps for now so won't consider the contact frame either. 2 reasons - quite tricky installing the frame (screw tightness important) and the design is more for alderlake although it supposedly can be used for raptorlake.

And yes, my cheapo mobo.... after learning about AC DC loadline, I cannot even set it because it is not in the bios! Lol! So I am losing out another 2 things for this cheapo mobo that could have made the temps even better. Cannot set VF curve. Cannot set AC DC loadline.

Anyway, scatterbench has some new info on setting the buggy VF curves. Will try it one of these days. I also asked intel support on the reason why the vf curve settings are not showing up on Intel XTU.

should avoid MSI motherboards atm until the secureboot issue tides over. now asus also kena dragged in kek

LOL its an easy fix if you know how to enter bios [Even though Secure Boot can be made effective again by just changing the Image Execution Policy options to "Deny Execute,"]
https://www.techspot.com/news/97285-firmwar...ndreds-msi.html

Only truly noob ones or those locked prebuilds using MSI mobo will be in some trouble, even then some hacker will have to specifically target that system.

MSI will soon sort this out as they have a reputation to maintain.

Its not RPL per se but related to K sku CPUs, this PL1 = PL2 = max TDP is seen in ADL K skus too. This almost always happens by default on Z mobo and on some B660 mobos too ie for Asus it will automatically turn on APE where PL1=PL2 state.

I am guessing a lot of those tuning functions you can't find is plainly becoz of how cheapo that mobo is specced. Have you tried contacting Asrock technical support? Maybe they know where are those setting hidden or something?

Yeah, I think it is because of this is entry-level mobo. I can't even get PCH temperature!

No, haven't contacted asrock yet. Waiting for intel to update me as they responded that they will look into the matter of missing VF curve in the Intel XTU.

Z chipset seems to be agnostic of other mobo components ie VRMs capacity. It probably doesn't care if its shitty 9 phases or Asus level 20 phases, as long as it detects K sku it will ramp up the same.

Another possibility could be this;
News from Reddit seems to indicate that Intel is locking ADL & RPL undervolting capability with newer bios updates
https://www.reddit.com/r/intel/comments/10d...nd_raptor_lake/

Thanks for the update. That could possibly the reason why I cannot set my VF curve offset to negative at all.

Mine was a z690 mobo that had to be bios updated on purchase to run the 13700k.

However, I'm lucky I can still do a global negative vcore offset.

wtf if K cpus are undervolt locked then time to see how 7000x3d performs
