Well explained with some of your OCTVB settings feels good to play at 6ghz , your the underrated king of the overclocking youtube content, At overclocking you are already king :D DDR5 overcloking guides or DDR4/5 in general would be awsome.

[@danielbekteshi8584]

I just copied all of these settings to my rig with a 13900KS, ProArt z790 being cooled by a arctic liquid freezer 360. Everything works great! I get roundabout 42,000 points in cinebench, have been using the pc with this overclock for over 1 month now and never had a blue screen. Saw on the comments that people were saying that it doesn't work because he has had luck with his chip, getting a sp predicion of 115 while most people get 107, I GET 105 AND EVERYTHING IS ROCK-SOLID. THANK YOU SO MUCH !!

[@brewmonger666]

Great video and guide, helped me a lot with my 13900ks but on a z690. I was having hight temps out of the box and initially only applied a -0.100 offset. After applying your settings now I have great temps and clocks.

[@johnmcmurphy1007]

The selection of the per core limit in 38:20 may only be applicable to your specific CPU and not to others. You also seem to have a highly selected and binned CPU with an SP prediction of 115 whereas the average is about 107. So it is very likely that everyone with a lower binned processor will get an unstable system even when exactly following your video. That's my case with an i9-13900KS at SP 108. Besides this, my comment is not meant to be a rant about your video which gives a fantastic insight into OC and the Rapor Lake Platform. Thank you for this! 👍🙂

[@lassekristensen385]

Mine is not 100% stable at those settings.. I have a KS 108 (p cores at 117). But CBR20 cannot complete and my browser closes random. I tried 1.48v in all volts that did not help so im gonna try a 1.5v tomorrow. But yes his KS has a VID @ 6 Ghz 1.439v which is pretty insane! My KS has VID @ 6 Ghz 1.469v EDIT: Changeing all adaptive voltages including VRM to 1.5v have resolved all issues! Record for me in CBR23 and CBR20 and CPU runs insane! Its a REAL treat to see the 6300 Mhz when active! ;) EDIT 2: Still not stable even at 1.52v ... What I am currently testing are 2 cores at 6300 Mhz instead of 3 .. I think that did the trick EDIT 3: 6300 Mhz are no matter what and how many cores causing random BSOD and sudden critical crash..This was with tested voltages all up to 1.55v. just to be sure it was not a power issue. Doom Eternal - any master level will SURELY tell you if your OC are stable. That engine are amazing and dont use 1 render thread but all the workers (cores) it can get. So its the ultimate OC test. Trust me! I can pass many test and benchmark but not Doom if the OC are unstable without you know it. I modified the OC profile to have 4 x 6200 Mhz and 8 x 6000 Mhz... THAT works ! this time tested throughly... several Doom Masterlevels passed! ;) Im gonna keep that and not pursue 6300 Mhz for now. Also my CPU now max use 1.46v but are almost all the time at 1.439v. Very very good settings. I think I know what the problem was. LLC 6 are simply not strong enough and have to much vdroop. And the very peak of the limits of the CPU 6300Mhz it does not work on my CPU. The other times I used Scatterbench examples I used LLC8. And that always work but is max LLC. I wanted to get away from that to get better performance overall. LLC6 NEVER worked on my regular K on Scatterbench examples.. I always used LLC8. But this profile are now rock solid with 4 cores at 6.2Ghz! and all core in game 8 x 6 Ghz at LLC6 and its sustainable with great temps etc. Runs amazing and what a treat to see my games and Doom Eternal running all core 6Ghz. Scatterbencher has an extreme bin of an KS. SO thats why he can do the very final step where I cant at least with these power settings.

What should SVID Behavior be set to? Auto? When mine is set to best case scenario it becomes unstable when trying to play a game. But if I set it to typical it goes up to 1.5v core.

[@SkatterBencher]

TLDR: Auto Long explanation: SVID Behavior adjusts the AC/DC LL (LoadLine), where best case is AC LL=0.01 (lowest) and worst-case some higher value. If AC LL = 0.01, then the voltage VID requested by the CPU to the voltage regulator will match 1:1 the CPU's factory-fused voltage-frequency curve. If AC LL > 0.01, then the voltage VID requested by the CPU to the voltage regulator will have a small (positive) offset to the voltage request. So the effective voltage will be slightly above the factory-fused voltage. If your VRM loadline is flat, so no Vdroop when the load increases, then setting AC LL=0.01 should be no issue. However, all motherboards have a VRM loadline configured. There are specific reasons for that, primarily related to small spikes in voltage overshoot and undershoot. The effect of VRM loadline is that the voltage regulator will manage the output voltage according to the load. For a given requested voltage, the effective output voltage will be lower as the load increases. The real-world effect of AC LL = 0.01 and a VRM LLC is that the effective voltage under a high load will effectively be lower than the CPU factory-fused voltage-frequency curve. For example, let's say the CPU needs 1.2V for 5.5G for stability. - If AC LL = 0.01, then CPU requests 1.2V from the voltage regulator - If VRM LLC = flat, then VRM will output 1.2V to the CPU (but there will be overshoot) - If VRM LLC = not flat, then the VRM will output 1.2V at no load and perhaps 1.15V at maximum load. That will cause instability of our CPU needs 1.2V. While some CPUs may be able to run stable when undervolted, not all can. If you wish to use SVID best case, you can also change the VRM LLC to a less steep loadline. Hope this helps :)

[@hadleys.4869]

@@SkatterBencher thank you for the explanation. I’m on the Asus ROG Maximus Z790 APEX with a 13900ks(overall SP 113, P core SP 123 E Core SP 96 MC SP 83). With SVID behavior set to Best Case, I cannot get a stable overclock, with SVID behavior set to Trained(Ai set) the max stable OC I can get is 60x/60x/58x/58x/58x/58x/58x/58x(1-8active cores)And LLC of 6. With SVID Behavior set to “Typical” and a Global SVID voltage negative offset of -.02v,LLC of 4, TVB enabled, TVB voltage optimizations disabled, I can get 61x/61x/60x/59x/59x/59x/59x/59x with e cores synced to 4.3Ghz. Should I even try to raise the E Cores if my main focus is gaming, which is usually medium cpu loads? Thank you! 😊

[@flaviobozzoli7323]

I share my experience, it may be useful to someone, I solved it by disabling CEP settings and putting six cores at 6.2ghz and 2 cores at 6.1ghz and all ecore at 4.5gh. I had to increase AC/DC to 0.15 now it is stable with occt and cinebench 23. Cinebench done 42628 as point.

[@DannyR121]

@SkatterBencher Thanks for the amount of work you have put in. I have one question. I'm using OC Strategy 3 with the sameish settings as you. 5.7Ghz all core under heavy load gets me to 85c. Should I go for 5.8Ghz and increase the adaptive tubo mode voltage?

[@SkatterBencher]

As an overclocker, I'd say give it a try and see if you can make 5.8G work :)

[@ThenewmanX1]

Very informative video.

[@shootloadrepeat]

Thanks for these guides, they're amazing at explaining what the settings do. I tried strategy #3 with my 14900KS and it runs extremely cool and stable. I know I'm using the 13900KS numbers and I could go higher, but everything is great and running conservatively. Also running 6000MT/S DIMMS and I used my 6Ghz as the values. However, what is strange is that I am getting only 22K scores in CB23, whereas before I was running 40K + although not stable in games. In your example, you're showing decent scores in Cinebench so I must have done something wrong. Volts are low, temps are low, I show boosting to 6.2 Ghz on 4 cores. Everything seems fine and I am happy with this, but feel like I may be leaving something on the table using such conservative numbers. (Latest Asus BIOS 1202 I think) I also didn't reset everything to defaults prior to starting, and was running Intel Failsafe before. (I know, this is wrong and I ran this for a day) Wonder if there are any insights to my situation.

[@SkatterBencher]

23K sounds pretty low even for conservative settings. Can you double check with HWiNFO what are the core effective clocks during a Cinebench run?

[@christycho9871]

very good guide. Sub'd. Perhaps if a 13900KS goes on sale, I'll upgrade and use this guide to optimize the setup.

I asked the same question hope he has time to answer.

[@ElijahSamsonWiltonChen]

Youre brilliant sir

[@ColinDyckes]

Thank you for answering my previous question. May I ask some more detailed questions in order to better understand what is happening and possible on my *delidded* 14900KS on a MoRa 420 (so not water temp limited) please, so that everyone can better understand some of your core multiplier settings ? : 1) At 320W default limit under R23 my P Core 7 is 20C hotter than the coolest core, with core 6 rather hot as well. Are these adjacent to the first two groups of E Cores? Reducing P Core 7 by 200MHz drops its temperature by 10C, from 100 to 90. I notice you often reduce two core multipliers and wondered if this was based on observed temperature or v/f curve. 2) Relating to question 1, if I were to plot all possible 13 v/f curves for any specific chip would that indicate the hottest cores by those needing the highest voltage for a multiplier? I know that the SVID requested will be the highest of the values. 3) Finally, is there any general guide to what undervolt is possible? Intel obviously program a margin. Is it something like the 10% that you seem to use? Thank you, and keep up the great overclocking guides. I doubt that anyone outside of Intel has your obvious expertise! P.S. I wonder if within your own overclocking utility it would be possible to extract and save all 13 v/f curves by independently adjusting them and saving values, just as can be done manually, but in a very time consuming manner, using XTU.

[@SkatterBencher]

Hi Colin, thanks for the kind words. I will try to answer as best as possible: 1a) The reason I limit the ratio of specific cores is not due to temperature or observed V/F curve. It is simply because those cores aren't stable at the highest defined Turbo Ratio Limit for 1/2-active cores. By limiting specific cores, I can still have my other cores hit those peak Turbo ratios. 1b) I'm not sure the reason why they're hotter are due to proximity of E-cores. Some cores might just be slightly leakier due to manufacturing variation. 2) Not necessarily. Some cores run lower voltage but hotter and others vice versa. That can be due to current leakage. V/F curve a good general predictor of core capability but, as we've seen with ASUS' SP values, it's not a defining predictor. 3) Great question. Think about it this way: if there was a general rule that could reliably predict the undervolt margin, then why wouldn't Intel leverage that to build faster or more power efficient chips? The reality is that Intel spends a great amount of resources to find what chips are capable of since higher performance (or perf/watt) means they can charge a higher price. That said, evidently there is margin as we're able to undervolt to a certain degree. But it's not easy to give any general rule other than, for example, "try 50mV and see if it works" just like we'd say to AMD Ryzen overclockers "Try -15 curve optimizer and see if it works." As for the software question: unfortunately extracting the V/F curves automatically is pretty difficult because you need to adjust several settings (like AC LL, VR LLC, TVB, etc) which cannot be changed at runtime. ASUS does a pretty good job providing some information through BIOS, but the only way to get accurate data at the moment is by doing it manually.

[@ColinDyckes]

@@SkatterBencher Thank you for the very detailed response. I'm attempting to use XTU to get the curves but hitting the problems you mentioned. I'll try again with Bios defaults and no TVB. If not then it's a very long process in the BIOS.

[@flaviobozzoli7323]

thanks for replying, I wasn't expecting it :D anyway, a very strange thing. Even with the stock settings, if I launch Occt, I have no errors until I connect any USB stick. errors come out but it doesn't crash. if I run other tests no type of error. absurd, every time I connect a USB occt device under stress it gives me errors even with stock values... maybe I have some other problem that causes instability in the overclock and I have no idea what it could depend on.

[@atr0ci0us187]

Will this guide work with a 14900k on a Z790i Asus mITX mobo, and Corsair Dominator Titanium 7600MHz RAM sticks? 9:03

[@SkatterBencher]

Yes, but the exactly frequency will depend on the cooling solution you're using.

[@shaolin95]

Hi! What can I tweak exactly to lower voltage little by little? I want to prevent it from ever hitting 100C and my Corsair link 170i is BARELY able to keep it right there from hitting but sometimes it still hits 100c as it is using alot of watts for even a 420mm AIO like the new Corsair Link. Thanks!!!!

[@lassekristensen385]

I use a different strategy now because I think this per core strat. is not good in the long run and can cause a lot of instability. It turned out that my cooling was not sufficient for those high clocks! What I did was I redid all my water blocks and LM and reseated the block on the GPU. Then I bought a Monster Radiator (yes that is its name! :) MO-RA 420 PRO.. Its massive with 2 extra pumps! This enabled me to run 6000 GHz all core with a OCTVB down clip at 70c and 80c. But the cooling is SO efficient that the CPU never gets to 70c. Only in extreme cases like CB R23. Then it clips to x58. But ALL games, even the most CPU intensive its now at 6 Ghz @ 48-58c max. Pretty incredible! (Direct Die) Its runs better than ever with not one single crash so far! (running 14 days!) Before I think what happened was occasionally it hit the ceiling and then made errors and BSOD/ Crash and or instability. So the no 1. thing is make sure the cooling can handle it. You may call it old school but all core is king imo. You don't really get anything useful out of per core imo. Also before I could not run LLC6 on 6 Ghz but its magically working now with new cooling! Please write if you want to know more. So my final settings are LLC 6, VRM Frequency manual 800hz, Powerphase and the other one on Extreme and VRM OFFSET Vcore +0.050v .. that runs the CPU @ 1.439/1.44v 100% stable and now also cool! ;) My SP is 108 and Cooling is 198

[@iXzenoS]

Thank you for this wonderful guide, however the stock values you listed for the 13900KS at around 3:40 is incorrect and misleading. The correct stock values within Intel's specs are as follows: PL1 = 150W PL2 = 253W TAU = unlimited IccMax = 307A (or 400A w/ Extreme Config profile) You can confirm this on Intel's site and datasheets.

[@SkatterBencher]

Since Alder Lake, for K processors, the default specification for Turbo Boost 2.0 is PL1=PL2. For the 13900KS, Intel also prepared an "extreme" specification which has PL1=PL2=320W. Unfortunately I had already finished my video before the new spec was released.

[@shaalomn3967]

Would like to see a RAM Oc guide 😊

[@kineticninja7989]

what values should you use for the core ratios for P-Cores and E-Cores when overclocking a 13900K? the 13900k guides you released seem to only OC the P-Cores but what if one wanted to OC both the P-cores and E-cores?

[@rccosplay3249]

First to comment! Great video as I'm taking a chance and exchanging the 13900K($579 USD) for the KS($699 USD). I sure hope to get some performance uplift in MSFS a very demanding title no doubt. I'm currently on the 12900K and it's doing ok. Even a few more FPS will make me happy💖

After unfortunatly damageing and kill my 13900K , I got my 13900KS today. I must admit although it runs GREAT! That I am very disappointed that its noway near as good as the example in the video! Yours has a VID @ 6 Ghz = 1.428v ... I think mine has like 1.468v or maybe even 1.478v. Thats quite a lot more ! :( Very disappointing now that I though I was a member of the "exclusive" club. I will try this 6.3 Ghz example though. I am runing a modded profile of yours for my previous 13900K but at 6.2 Ghz for my KS. So far no issues! I even run cache at 5 Ghz permanent. I will throw a EKWB Direct Die kit on it in a few weeks. Now the KS is watercooled with a Thermal-something contact frame.. (the other one than the TG) :) Love your content SkatterBencher! ;) EDIT 2: 6300 Mhz are no matter what and how many cores causing random BSOD and sudden critical crash..This was with tested voltages all up to 1.55v. just to be sure it was not a power issue. Doom Eternal - any master level will SURELY tell you if your OC are stable. That engine are amazing and dont use 1 render thread but all the workers (cores) it can get. So its the ultimate OC test.

Also my CPU now max use 1.46v but are almost all the time at 1.439v. Very very good settings. I think I know what the problem was. LLC 6 are simply not strong enough and have to much vdroop.

I wanted to get away from that to get better performance overall. LLC6 NEVER worked on my regular K on Scatterbench examples.. I always used LLC8. But this profile are now rock solid with 4 cores at 6.2Ghz! and all core in game 8 x 6 Ghz at LLC6 and its sustainable with great temps etc. Runs amazing and what a treat to see my games and Doom Eternal running all core 6Ghz. Scatterbencher has an extreme bin of an KS. SO thats why he can do the very final step where I cant at least with these power settings.

For some reason my Z790 Hero when I have everything at default with MultiCore Enhancement disabled my 13900KS is not sticking to it's default PL1 AND PL2 Limit as it is setting them both of the limits to 320.0W for both of them. So I can not get the chip to run at stock could this be a fault with the bios ? I am using Bios ver. 0813

[@SkatterBencher]

After I finished my video, Intel released a new Extreme Power Delivery specification for the 13900KS processor which has PL1=PL2=320W, not 253W. So your default specifications are correct www.coolaler.com.tw/coolalercbb//INTEL13TH/13900K/ClipKS_1.jpg

Great explanation. For Raptor Lake on Asus motherboards the V/F Curve for the P Cores is directly visible, but how do you get the E Core and Ring curves? Any help would be much appreciated.

[@SkatterBencher]

The only way is manual checking. Set P-core to 8X and then the VccIA voltage is determined by either E-Core or Ring. Also set ring to 8X and then the VccIA voltage is determined by the E-Core.

[@ashryver3605]

Can you please explain what TVB Voltage Optimizations and Enhanced TVB does? Everything i can find about TVB just talks about the actual temperature bin feature. Also is it necessary to go into the by core section and set 1.475? I have my TVB set up as 62x2, 61x4, 58,6, 56x6 with 50-55c as the limit for -1 bin. I have those 2 settings enabled and I never touched the specific core frequency or clocks. The peak voltage is about 1.415 when it clocks up to 6.2 in desktop, and under extreme load 2.5b it goes down to 1.181v when at 8 cores.

[@SkatterBencher]

I have a page up on my blog that explains Voltage Optimizations skatterbencher.com/intel-thermal-velocity-boost/ The Enhanced TVB function has changed between SKUs, so it's not a clearly defined function. If I remember correctly, for all SKUs, except 12900KS, EVTB = Vmax Stress (limit voltage), and for 12900KS ETVB = Tmax Stress (clipping ratio based on temperature.

[@a_doggo]

Amazing video! Can you give any advice on undervolting/minimizing the power draw of my system? I run a 16-thread workload on my E-cores and want to minimize their power usage, but when I increase my P-core speeds, it raises my E-core voltages - and they use as much power as if I'd raised their multipliers! I'm using XTU and the voltage offsets for E-cores don't seem to do anything. I'm currently running them at 26x (I mostly run at 26x lol), but the system starts using far more power if I raise any of my multipliers. I'm trying to make an optimized low-power mode.

I also had the 13900K and for that CPU I would highly recommed Skatterbenchers "6000 Mhz 13900K" I tried all profiles also and found that best for that particular CPU with that SP and powerdraw- ..6100 or his 6000 Mhz 13900K profiles runs great for that CPU. 6100 Mhz profiles will however require additional powerdraw and cooling. I found the 6000 Mhz profile to be best daily driver. And now I just configured this 6300 Mhz KS profile on my new 13900KS ... runs amazing! A real treat to see the 6300Mhz when active! I did however had to change all voltages to 1.5v to make it stable. My KS are not as high bin as skatterbenchers.

[@iAmTheJT]

Bro I have SP 96 with my 13900k. That's the average of all 24 cores. Usually the E-Cores are what brings it down. Go to Extreme Tweaker/AI Features to see P-Core SP and E-Core SP. Mine are P-Core SP is 107 and E-Core SP 76. Average is 96. Unfortunately once the KS went into development, all of the higher binned 13900k chips became 13900ks chips so the later you got a 13900k, usually the worst it is. I'm unhappy with mine but it's whatever I guess.

i followed your step by step guide for 6.3ghz in my z790 apex and 13900ks. I have some slight instability, could you suggest me how to set IA AC/DC Load Line to get stability?

[@SkatterBencher]

Assuming you're on the edge of stability, you can try increasing the AC loadline in steps of 0.05. This will cause the CPU to request higher voltages from the VR controller, thus (hopefully) improving stability. Don't go too high with the AC loadline though ... sometimes you just need to accept that the silicon lottery is not on your side :)

Do you think leaving it on Strategy 2 (AI Overclock Method) for longer periods of time will return higher and higher performance (benchmarks) over time as opposed to setting it and testing it right away, as it learns over periods of time and periods of use and adjusts/tweaks the overclocking settings on it's own w/ learning?

I dont think so, it will only make small voltage adjustments based on cooler score. I think its based AI OC is on fused VID, SP quality along with cooler score of corse.

Sounds like the overclock is not quite stable. You can try either of the following options: 1) Reset to defaults, go in the OS and run Cinebench R23 for 30min to "train" the motherboard. Then try AI OC again. 2) If too low voltage is the root cause of the instability, you can also try adjusting to a less steep VRM LLC

Vdroop is not something that would be reported in HWiNFO directly. You have to infer it from the Vcore information. For example, if the Vcore is 1.25V at 50X in idle but 1.15V at 50X in all-core load, then the Vdroop is 0.1V

[@eeeo2196]

I’m wondering if that’s optimal for gaming?

[@HollywoodEDC]

Hey @SkatterBencher I got a serious question and I apologize if you have covered this before. With ALL of your overclocks, your temps are atrocious. I realize it does 0 harm to run 13th gen and i9 at 95C-105C, however IT DOES throttle the hell out of your speed and continuously retard clocks back. So why not work in "undevolt" mechanics and reduce some of that heat, so that you arent TJ Max'ing directly into down throttle? Wouldn't you see FAR SUPERIOR results if you managed to overclock your mem+cpu and retain turboboost? I would think your results would be FAR superior if you managed to keep temps hovering between 85C-95C and retained your turbo clock throughput during the entire test bench window (and or indefinitely?). I've seen people run HWINFO64 and run all 8 P-Cores at 6GHZ with less than 300 WATTS and temps all under 95C. With your tests and results, your always averaging 100C with max 100C and your P-Core Clocks all at like 5.5 or 5.7 depending on which OC method you used. This tells me your throttling back significantly? Maybe I am entirely wrong hear and I hope I am, in which you could explain why and how please. Because I just dont see the benefit or gain from ANY of your OC"s. ALL of them look like they yield HORRRRRRRRIBLE results from glancing at your min/max in HWINFO and your scores in general. What am I missing here?!?

[@SkatterBencher]

I only report in detail on the worst-case stability tests (Prime95 Small FFTs), not other benchmarks. So the temperature in, let's say games, usually wouldn't hit 100C and it wouldn't throttle the CPU frequency.

[@schmierer84]

Could you explain how to Check for instabilities During transient loads and single core boost?

[@SkatterBencher]

Sit at idle for a while, then run a heavy workload. I have used 3 ways to detect these issues: 1) Sit idle, then load Prime95 Small FFTs all-core (non-avx & avx) 2) Run Cinebench R23 with 30min time (between runs the CPU goes to idle briefly before running all cores again) 3) Use AI Benchmark (very varied workload that often catches this instability)

[@juanandreas97]

why i need to run cinebench before enter AI overclock menus?

[@SkatterBencher]

Because the onboard embedded controller (EC) needs data on your cooler's capability to handle high loads. Running Cinebench helps the EC understand how fast and at which power consumption the cooler keeps the CPU at a certain temperature. Without the data, the algorithm is flying blind

[@sensationsuperthrust]

Isnt OCTVB for 1x and 2x active cores still limited by how high the WORST core on the chip can boost while retaining stabilty?

[@SkatterBencher]

Not if you also configure the Per Core Ratio Limit correctly. That tool allows you to limit the maximum ratio of specific cores

[@sensationsuperthrust]

@@SkatterBencher ah damn i thought this was the 13600k video, got the comment box mixed up... Since TBM 3.0 is not available for the 13600k and thus the os will not prioritize the cores best to worst, the 600k will loose some single core performance on average, especially if there is a large gap between best and worst core, right?

[@lassekristensen385]

On ASUS there are something called "Multi Core Enhancement" under Xtreme Tweaker..... There are 3 options. Enabled let BIOS optimize. is basically a semi unlocked "power draw profile" Then there is ENABLED REMOVE ALL LIMITS (the one you want and should try!) it unlocked power limit totally. And finally the setting I believe you are using is DISABLED - ENFORCE ALL LIMITS! this will limit the CPU no matter what to 253w. When unlocked with aggresive settings you should could be able to draw 320-350w depending on cooling.

[@YTaccount11454]

in the "simple manual overclock" you say "we get these results because of the aggressive undervolting" but looking at the guide i don't see any undervolting happening? all you do is setting the adaptive turbo mode cpu core voltage to 1.43500 which is higher than the VID tables 1.42800 which does makes sense since you are increasing the max boost, but where is the undervolting? I don't understand

[@SkatterBencher]

I explain the undervolting part in the segment "VccIA Voltage Rail" kzbin.info/www/bejne/mqG6qJJrgMujf9k. The undervolting is not in the traditional sense, where we would set the a negative voltage offset, but using AC loadline and VRM loadline. TLDR: there's undervolting because the CPU voltage is below the fused V/F curve when under load, due to AC and VRM loadline configuration

[@YTaccount11454]

Truly appreciate your time to answer my stupid question, i guess i somehow missed that part. I did use your guide to apply my overclock but i really wanted to try to understand why it was working... is there anywhere in the video where you disclose how you come to the decision in using 1.43500 as the adaptive voltage? i had to use 1.45600 adaptive voltage to stabilize my 14900k.
