[@dukett2430]

Perfect timing Jay! I was literally stumped on the XTU, blocked by windows defender. This is classic Jay, on point tutorial. I heard about undervolting, was interested, now I'm using it.

[@garyalexander2967]

To the commenters asking for AMD: Benchmark your CPU at stock. Write down the results. Go to PBO, pick the max negative offset you can get that's stable. Benchmark again and write down the results (they should be higher). Then go back into the BIOS and lower the target temperature in PBO until your benchmark results drop to around the first number. There you go!

[@musicalintelligence]

ASUS mobos have a hard time with PBO. My Creator is absolutely allergic to any automatic tweaking and I am tired of pulling my GPU out to reset the bios.

[@bushi1147]

​​@@musicalintelligenceIf you have armory crate on it will screw with specs but you can technically overclock using Amory crate

[@Deadwillpower1001]

What is PBO. I cant remember for the life of me.

[@thejamiestarbuck]

@@Deadwillpower1001 Precision Boost Overdrive

[@IT10T]

@@musicalintelligence Yeah, I find that the offset potential is somewhat relational to the overclocking spec on the DIMM. I seem to be able to do better if I do not max out the XMP, I think DOCP is whack, also if you overclock CPU and not the RAM, the VCC and VOC will be all cracked out and jumpy like its on drugs. I hear Gigabyte had the same issue until their BIOS update in May.

[@zackzeed]

I knew some of this already but It's very much appreciated to get a nice refresh from someone who knows! Thanks Jay!

[@catpsyche]

Jay, I really like how your brain works! You're articulate, you talk things through, not afraid walk your way backwards out of something that you said too quickly and explain your reasoning, and overall an excellent communicator. I maybe late to the game and to subscribing but totally enjoying catching up on all your most recent vids. Thanks so much! Helps me greatly in planning out my first build... And the thing is I'm sure MOST don't just watch vids like this - one and done! But rewatch, II, , into infinity til we totally get it.

I too would like to see Jay do this with i9-13900k. I have Asus ROG Strix z790-E Gaming. I really hope he can revisit with this

[@stephenvp]

​@RJWca i dont think xtu will save your settings on a z790. Youll have to undervolt in the bios. Im having the same issue. This video is for the 12900k and a different motherboard. Its irrelevant for us. Temps are still ASTRONOMICAL for the 139000k even witha .05 undervolt and stock clocks.

[@RJWca]

@stephenvp I'm not undervolting anymore with an external software letting AI do it and so far it's been months with no problems at all!

[@ArtFiendz]

@@RJWca AI was doing a great job with my 14900k on an Asus ROG Strix z690-e gaming, but with my new Asus ROG Maximus z790 hero it's way too hot and can't figure it out for some reason. I knew how to overlock pretty decently when i had a 9900k but with the E-cores and P-cores I can't seem to grasp it properly. I definitely need to undervolt or something because my 14900k is throttling in cinebench r23 on stock.

[@RJWca]

@ArtFiendz Update All my system z790-E with Asus ROG 4090 OC and 7800mt 32GB ddr5 have been working great since keeping it updated to the newest bios with armory crate taking care with AI fan control.

[@deadzeye9007]

One of the biggest factor I noticed in high temps is the ambient room temp. I live in a tropical country and i tend to turn off my AC 14 hours of the day. And while turned off, my gpu tends to reach 90+ C.

[@bradarmstrong6919]

I'm curious why you turn off the A/C for 14 hours? I'm in the trades and most HVAC workers say it's better to keep it always on, otherwise it has to work longer and it is harder on the compressor.

I had no idea these ran so hot when building this PC, and if I did I may have went another route, but now I'm seeing about 45°C at idle and 75°C while under load. Not bad for a Noctua NH-L12 Ghost!

Thanks Jay for the video. I would be interested by the Load Line Calibration settings and other advanced OC stuff. Would you consider a follow-up video about that, please ?

[@iikatinggangsengii2471]

thing is each cpu has different voltage values, different board also add randomness factor it relates with the stress/ stability test program used, and apps afterwards so yeah, just try i guess is the best advice

[@mickeyriola9087]

That’s true ^ and he does have another video messing with that at least as of rn idk the name of the video but it’s not very old

[@danielwhite1670]

It's definitely a good piece of software. My 10900k would be hitting 90+ on Cinebench until I adjusted my voltages. Motherboards do tend to send way too much power to the CPU on even default settings at times.

[@zike4032]

Could you help me do the same, I got 11-400f like 50-60 at desktop idle and 90+ on games, driving me crazy. Cooler check, reapplying thermal paste nothing will make it lower.

[@netiturtle]

Seems like a good way to find the limits of your system and mirror them to BIOS. And ditch XTU, I'm allergic to applets running in backround. But I don't know how granual control Intel allows, they have a habit of taking away control from users, even settings that are harmless or even beneficial to longevity of CPU. Like undervolting with non-K models or cheaper chipsets

[@patrickryan3067]

Thanks for the video. Recently upgraded to 13900k and temps are outrageous. Will give this a try. I’d like to see more on load line calibration settings. That would be a good topic to do a deeper dive on. Also, currently having some issues running 64gb of ddr5 with xmp enabled at 6400Mhz. Heard others complain about Intel 12/13gen running full dimms with OCs. Maybe you could touch on that at some point. Appreciate all your content, Cheers!

[@mrufo2297]

Are you running ram rated at 6400 stock or OC to 6400? All 4 slots at 16 each from what you said, right? What motherboard?

[@NicoGylis]

what does you mb doc says about supported frequencies for 4 1R dimm ? usually with ddr5 2 1R > 2 2R > 4 1R > 4 2R in term of supported frequencies and 16Go is most of the time 1R

[@wiseanime2875]

also curios if you are trying 2x32 or 4x16? I've read that the 4x configs dont play well with any oc over 5600. also which moba you running?

[@Frozoken]

​@NicoGylis yeah and ironically enough if you have a 2 dimm board which is almost always itx or an overclocking board, dual rank x2 goes from like a +200mhz advantage over 4x1 rank to like + 800mhz so if you're a creator needing fast high capacity ram the "creator" boards will leave you much worse off 😂.Msi is the best example of this seeing they say their supported speeds for all mem configs and their $300 itx board supports 600mhz higher mem clocks in dual rank than their like $1500 z790 godlike.

7:55 vid is the requested voltage NOT the actual vcore the cpu is receiving

[@Need4FPS]

If you wanna play it safe, just leave everything stock / auto when it comes to frequency .. just apply small offset to voltage and change LLC to something like normal behaviour. The boost that you will get in regards to FPS with newer gen of CPUs especially if you re playing on higher resolution is completely irrelevant. Did some testing with bit older hardware, and with MID OC of CPU and GPU in majority of the games was like between 2-4 FPS difference on 4k resolution. Would say, waste of time. (But small offset gets you lower temps, and just leave the frequency be)

[@RetroPlays1]

I have a 12700kf with a 240mm AIO when it was in a case that had horrible air flow my cpu running cyberpunk went up to 91c or higher. Had to take of the side panel and it immediately dropped to 70c. So I just got the O11 Mini Airflow with all new case fans and Liquid Metal on the Cpu and water block. My cpu temps are now 50c or lower and I’m blown away how much the Liquid Metal has helped the temps and the better case and fans as well

[@FearInSilence.]

Hey everyone , I have watched 50+ videos re arranging bios settings and tried many softwares but nothing worked for the past 3 weeks as i person who has received a new pc i was worried but after wasting my time on all of these videos , I went to my guy who build my pc and he changed the orientation of my cpu cooler fan.

[@chincemagnet]

My z790 Aorus Master had my 13900K set to 1.5v out of the box!! It immediately thermal throttled, even though I have a high end liquid cooling system. Not surprising. When I saw the voltage I was like 😳 anyway, I dropped the voltage a lot, around 1.2v and it still clocks to 5.7 on all the p cores, and a bios update which helped immensely, so that’s also a high priority. I can’t remember when or if I ever had to undervolt a cpu before in 20 years.

[@sxzoR11]

Hey mate, did you undervolt in BIOS or with XTU? We have the same mb and cpu. My temps are perma 100c when on full load.

[@chincemagnet]

@@sxzoR11 I would also recommend turning off MCE (multi core enhancement) and other over clocking setting until you get it to stop thermal throttling, run it at stock, set it to fixed voltage, turn off XTU for the RAM, just until you can get it to stop thermal throttling, also set load line to a mediumish setting, then once you know everything is going to work correctly, then start tweaking.

[@chincemagnet]

@@sxzoR11 another thing that just occurred to me is I’m using the Thermalright contact frame for 13th gen, that’s supposed to help quite a bit with temps and it’s cheap by comparison if you paid for this board and cpu combo, it’s on Amazon and some other stores. I never tested without it, so I don’t have numbers, but there are videos that show a comparison of stock vs the contract frame

[@viktorhenzel7655]

Just a few days ago I found one setting that fixes everything. So I have a z390 board from Msi with an i9 9900k. So basically my cpu always hits 100c on all core in cinebench r23 with about 220-260 watts (score ≈10k). Voltage was at 1,46. Now I found out that there is a setting wich was called CPU lite load standard was mode 11, tested the modes and found out that mode 4 runs perfectly stable now with voltage at 1,25 and temps are around high 70s and low 80s in cinebench at 170 watts which results in a score of about 13k.

[@vMaxHeadroom]

Totally agree as I found that setting recently as well. On my MSI Z790 and 13700K overclocked, I was hitting a 100 degrees in Cinebench R23 multicore test, with the lite load setting dropped to mode 5 the temps are great now and in the mid 80's especially for a nice all core 5.4GHz overclock on a 13700K with a max under load voltage at 1.264v and pullling 239w in CBr23....had to search the OC forums but what a great setting to have...

[@viktorhenzel7655]

@@vMaxHeadroom nice improvements. I’m glade that this function still remains in the newer board definitely makes upgrade and optimization easier. I still don’t think it’s the right way to fix the stability problem, either intel or the motherboard manufacturer should implement a fix. Why doesn’t intel calibrate all the chips in the testing phase so that they work how they intended, I think they should be able to save some kind of personalized voltage curve on to the cpu. And the other solution would be, some kind of first boot/configuration setup in the bios where the first thing should be optimizing the voltage, for the user

[@BNR_248]

@4:00 i disagree Jay, I ran cinebench non stop on my 10900k to test the overclock and it ran fine, however, I launched battlefield and it crashed with Whea_uncorrectable_error loading into the game. As a result i started using Linpack extreme instead, 3 runs of the stress test it crashed immediately, altered my voltage, ran linpack again for 3 more rounds, it was perfect. Launched battlefield with the same OC but better voltage curve and its ran perfect ever since. Cinebench only tests the core clock itself, core clock OC can affect memory and cache, which cinebench does not test..Linpack does AVX and nonavx instructions, also loads up cache and ram. Covers all possibilities.

[@bradclapp4022]

I feel like Jay was trying to say it's a good test to max out the temps. This definitely needs clarification. You definitely need to run multiple types of stress test to ensure stability.

[@dyson9422]

I have been building computers for an AI developer who works from home in an area with slow internet service. While coding can be done on a laptop, testing is done on a PC that I assembled with a 13900k CPU held down by a Thermal Grizzly Contact Frame and cooled by a Noctua NH-U12a and a 4090 GPU. With FurMark running on the GPU, the CPU was under 90 C while running Cinebench R23 doing a 30 minute stress test in a 25 C ambient. The multi thread score was just over 38000. Intel XTU makes getting the most out of CPU lottery and cooling solution a lot more time efficient. Cooling solutions also need to be efficient over time. Dust decreases the cooling efficiency and dust increases with fan speed (air flow). Dust will accumulate exponentially with time. This means that an initial temperature margin, e.g. 90C, will be needed to compensate for the inevitable accumulation of dust. CPU temperature will increase exponentially with frequency. The CPU and its bios will use a higher frequency and voltage (turbo boost) on a core if the temperature and voltage and maximum frequency will allow. This seems like a good idea but it depends on the cooling solution. This turbo boost can use more of the thermal budget than the ideal heat/work ratio. This will cause less work for a targeted temperature margin. A quick indication that the maximum frequency is too high is that the Windows Task Manager reports a CPU speed much lower than the maximum frequency. The best indicator is the Cinebench score at your target CPU temperature. The best PC motherboard fan curves will remove the heat with the minimum air flow. This will make less dust and noise. By adjusting the fan curves and maximum frequency the curve should look similar to the table below. CPU C 40 50 60 70 80 90 94 Fan % 0 10 15 40 70 90 100 The number, size of the fans, and fan speed of the fans that help remove air (exhaust) should be sized to maintain positive pressure in the PC case from filtered air.

[@genejones7902]

Running a 13900KS and stock hits 101°C and mid 37k CB pts. CPU uses 330W peak and bounces between 300-320W while thermal throttling throughout the run. Fun facts: 1. Cinebench R23 yields higher scores if task manager priority is set to high, or if you don't mind your cursor being extremely slow or freezing for 10 minutes, set it to real-time. 😊 2. linpack Xtreme uses even more power! 😮 3. ASRock motherboards, until a recent BIOS update, was setting TjMax on 13900K / KS to 115°C. 4. 14900K will burn a hole through your mobo. 5. Thanks Jay for making this helpful video! 🤓

[@ashryver3605]

14th refresh is intended to be less power hungry as 13. Its not a true new generation, just a refresh and enabling a power feature that wasn't ready for 13th. The real question is "by how much".

YIKES! ) 0:34 I would have taught the viewer the benefit of BIOS overclocking versus invasive software that either has a profile initiated upon OS boot or can actually have permission to alter anything further in on the BIOS level. I mean I'm not trying to hate on Intel here, it's a great application to perhaps initial vet and bin a chip in a user-friendly environment BUT once done so go for and learn the ins and out of your own BIOSes where these overlocks should really be altered and applied, especially for a "real" all day and reliable overclock regardless of an under-volt or reaching for the stars...

[@Bandana_Assault]

XTU does not work for B660 chipsets as it pertains to undervolting within XTU due to plundervolt. Intel has yet to update to allow us to undervolt under these chipsets. You can make any changes within Throttlestop and it will ignore any of the changes due to the same reason. I had to underclock to get my thermals under control (a previous video Jay did :) until something changes)

[@johngregorio1209]

I also would like some help undervolting the 9750 in my Alienware m15 r1 since plundervolt. Jay, please help. My laptop isn't that old and deserves to run cooler!

[@Bandana_Assault]

@@johngregorio1209 you probably need to do what I did and underclock it.

[@Simmymind360]

Thank you Jay..this really helped, I wasn't saving on reboot and I had Ai on in Bios...I have a i913900k can get 6 at 55-60 temps..and that was with 5.0 V um..I'm excited to try some more settings in XCU

[@_khayjeet_]

As i don't want exhausted hot air from a 95°C hot 7700X, i simply set the max temperarure to 60°C in the BIOS. That might cost me around 15% performance, but i *gladly* take that drop if that means an insane 35 degrees drop in temperature.

[@VeggyZ]

I am going to have to try this once I'm feeling a little more motivated. I just completed my i9 13900K build and I freaking love it - and surprisingly, my Corsair H170i AIO seems to be keeping it pretty damn cool during normal gaming - I have not run something like cinebench though, at least not yet - I would rather have my ...planned cooling setups complete before I even let a program like that touch my chip and fry some eggs on it, haha... it scares the piss out of me... to be completely honest. I get it - this stuff is designed to run hot. I've understood that about certain brands and products for years and years, but it does not alleviate my uh... trepidation? Yeah, not really. I don't even TEST with benchmarks until I've got overkill solutions or just plain perfect airflow through the case in addition.

[@scottyc3215]

The thermal throttle should save you from damage in most cases. That being said, I'm currently trying to get the 13900k to run at any sort of reasonable temperature and losing. Even with a good AIO, and a steep undervolt, it's still hitting the 100C thermal throttle after a few rounds of Cinebench.

[@scottyc3215]

Alright, I think I'm done for now. P-core and E-Core ratios left the same, at 55x and 43x, respectively. I got the Core Voltage Offset down to -0.085V without any crashes, and just stopped there. That brought the peak temps down to max 90C, which is good enough. I might've been able to bring it down farther, but didn't see the point. Additionally, it should be noted that one of the biggest factors here was actually removing the front and top panels from the case for better airflow. If you haven't tried it, do so. Especially if your AIO is set to exhaust out the top, the heat can just sit on the outside of the rad, heating things up more than you'd think.

[@catpsyche]

@@scottyc3215 With so many variables it's important to note and remember, IF you're a freeze baby and like your home warm and cozy your PC will fry along with you! The cooler you keep your ambient home or PC area overall the cooler and lower your PC temps will be in general.

[@scottyc3215]

@@catpsyche This is true. I generally like it cooler in my game room, but the ambient temps do tend to climb the longer I play. Having air conditioning certainly helps if that's available.

Did you change voltage in xtu or in bios, i would like to do it in bios myself, as i heard alot that xtu dont always save the settings after a reboot.@@scottyc3215

[@timmycraft4332]

Unrelated to bios overclock, anyone notice XTU options just doesn't work anymore? :) Both on my new PC and legion laptop, where it was working a while ago, no bios updates at all, just greyed out now. Even older XTU versions.

[@ipann6693]

Working fine for me

[@MyNameIsTimIThink]

Ive been undervolting for years thanks to jays old videos

[@Alberos]

I just build the new system with 13700K two weeks ago..... and this thing run HOT. It went straight up to 97C after a couple sec of Cinebench R23 with a 360 AIO, not the EK AIO, would like to get it but they don't have stock :(. I plan to do undervolting from the start so perfect timing video that you updating this topic. Now to see if I win the lottery or not.

[@antonstanchev]

Hey man, i have a 13700K paired with a Galahad 360 AIO and I would like to know what stable settings did you manage to get with XTU, thx

[@Alberos]

@@antonstanchev I'm running -0.015v offset, couldn't go lower, stability issue on non-cinebench task. I have it hard set in the BIOS since XTU keep resetting itself. Didn't change any multiplier. Now running at 90-94C on the hottest (Cinebench) at 1.25v ish , 235W. All the BIOS optimize still on. Keep in mind I'm in a place where 30C ambient temp is "cool early morning" and can get up to 35C.

[@HexerPsy]

I thought XTU also allowed you to set max speed limits for individual cores to keep the weaker cores from going too fast... There is probably a whole other space to search if you go down to the individual level.

[@Spiralem]

Yeah, you can perform per core ratio tuning in XTU.

[@HexerPsy]

@@Spiralem I am currently on a Ryzen CPU - and my most recent intel CPU doesnt allow that feature. How do you determine which core has crashed on the intel platform?

[@Spiralem]

@@HexerPsy Sorry, not familiar with AMD side of things.

@@Spiralem I am not asking about AMD's side --- How do you determine on the intel platform which of your CPU cores crashed, if you want to do per core tuning?

[@DragonBane299]

Hey Jay Back In January, I was able to undervolt my 13900k, but apparently an update somewhere between then and now lead to XTU showing an "Undervolt Protection is enabled and will prevent voltage from being set below the boot-time voltage" I tried disabling the undervolt protection in the BIOS, but that leads to XTU refusing to launch at all. The application still works fine, I am able to apply an overclock and add voltages, just not undervolt.

[@bradleypearson3078]

Mine has also done this I am using a Asus prime a board and no matter what I do I can't apply an undervolt in xtu

[@jgo7870]

me too, can't run xtu without enabling undervolt protection, but then can't undervolt in xtu, dum

[@H4xooR]

I saw a tip under a different video,that you may can go around this,with using older version of XTU,to "bypass" this undervolt protection. However,i only got 10700k,so it is working for me,since it is older gen.

[@bradleypearson3078]

@@H4xooR I will definitely give this a try

[@bradleypearson3078]

So I just redownloaded xtu and havent changed anything since I last used it and it works fine now, it just doesn't seem to work correctly for some reason so I still have to use my bios

[@cool_cat007smoove3]

Great video segment. Turn off the turbo boost OC and set the cores to Auto in the bios. Then you are done.

THANK YOU SO MUCH JayzTwoCents you literally saved my pc!❤

[@darknessblades]

I undervolted my powercolor red devil RX7900XT. with around 15% it uses 150-200W less power total. and has barely a decrease of 5% in performance

[@adridell]

That sounds like some major b*llsh*t, 200 watts reduction not even in your dreams unless comparing to an overclocking where the processor is highly inefficient, even then I'd be skeptical of a 200 watts gain, but compared to stock power settings no way.

[@levigoldson4242]

Yes, I get very similar results in the undervolting the 13900k. Both companies seem to be making dumb performance decisions out of the box to win the benchmarks.

[@-offline]

Hey Jay, I just got a 5800X and it just shoots to 85C under any load and stays there. It would be extremely helpful if you make one of these videos for AMD as well as I'm dealing with an AMD processor for the very first time in my life. :)

[@mk5_FSI]

What are your specs? Usually mine lands around 60 to 65c underload so there might be a problem with cooling or not enough cooling also might be worth it to check fans and tune your cpu fan

[@bafon]

Download Ryzen Master, hit curve optimizer, take a coffee while the computah does its thingy, when its done you can enable PBO, then offset the hz by +200Mhz.That's pretty much it for AMD, it's just a toggle and the rest is automatic. You may want to go into BIOS and tick off "let motherboard limit power" if you have that option, but it is not a big deal in my opinion performance wise. But for your temps under any load, I would have done a remounting of the cooler, make sure that you have not left any plastic between the cooler and cpu, is the amount of thermal paste enough, does it make proper contact with the cooler and cpu? Are you using the correct mounts for the cooler? Did you screw down the cooler following a star pattern and only just a few turns on each screw repeated until the cooler had enough pressure? Too much pressure may also cause high temps.

[@seannyandme]

@@Liq38 Yes - I am hitting 90, AAA gaming at 4k, with ultra settings. And before I set the 90 limit, I saw way over 100 while gaming. I haven't done any BIOS voltage offset because when I tried this it wouldn't boot and had to reset everything.

[@Ram21s]

I really appreciate this guide for Intel, could you do a similar for AMD? Since summer hit I've been wanting to update my overclock and I noticed that my AMD rig is pulling a ton of voltage when it doesn't need to be. You guys rock!

No, you don't overclock AMD. Just undervolt it, and let it do the boost thing on its own. The cooler you get, you'll see better results.

cheeeeeeeeeeeeeeeeeeeeeers!!!!! this is DEFFINITLY what i need to know as i decide if im gonna go am4 or am5 cause ive nenver done any adjustments outside of oem boost clocks so i know for sure even the 3xd series will want a nice little undervolt so im super excited to have a second rig for the first time ever to REALLY dig into it and try to be fancy

I'm not sure why there's so much trouble cooling this chip. I have one paired with the ASUS rog strix 360mm aio, the chip is overclocked and I haven't seen the chip go over 65C playing modern titles max settings with a 4090. Starting certain games it reaches into the 70s but thats it.

[@ledoynier3694]

When you play it never goes to temperatures like Cinebench generates. If you go that route my 13900k caps around 80°C running cinebench, but never reaches 60 in game. Comparing apples and oranges.

I agree with those below asking about AMD 5000 series. Ive tried to look for info on it elsewhere (other videos/forums) and hardly any of it is straightforward and layed out in a simple to follow format the average person could understand (not to knock down any IQ points i may have, but everything ive read seems like its written by OC enthusiasts who dont take lamens into consideration)

[@simonbelmont0993]

So I bought a prebuilt from Best Buy. It's got an i7-13700kf, 32gb ram, and Nvidia 4070 ti on an ASROCK z690. It came with an AIO (not sure of the brand Cyberpower uses). Anyway, this thing runs _damn_ hot. According to HWMonitor I'm peaking at 99c during most high end gaming sessions (Baldur's Gate 3 and Diablo 4 recently) with an idle temp of around 55-60c. I'm going to try the methods in this video and see if they help.
