CPU Undervolting Guide | AMD Ryzen 7 5800X | Step by Step How To Guide | Ryzen 5000 Series 

Let me know if this guide was any help to you! Let me know the numbers that worked for your cpu! If you want to skip ahead please see the time stamps in the description!

Thanks! Exactly what I needed to know. Had a Ryzen 5800x that was spiking over 100 degrees and shutting down while transncoding to a h265 video. Your video got me at 60 degrees and finished the encode. Awesome!

Shaved off about 8-10c from my temps which were running at 87-89c when gaming. And you explained it like I was 10 years old like I needed, thank you.

Thanks for the guide! Finally found one easy to follow and understand 🙌

Thank you for the guide, it helped me massively. I was getting 90c plus in cinebench, at 4.5MHz. I used the settings in the video as a starting point and it dropped my temp to 82c, bought my power draw down 25w and I hit 4.6MHz. It raised my score by 100pts. I'll play around with the numbers now but what a great place to start, thanks again!

Saved my pc with your video. Much appreciated.👍🏽

I used this for an intro to get me to a good starting point, cheers!

This helped a bunch! Forgot to flash my bios before changing cpus. Fixed then you popped up and made my night 🙌

This was the best tutorial I have found. I just YOLO'ed it and used those exact settings you suggested and I have dropped 9-10 degrees at 100% utilization. Before I was at 81.5 and now max is like 71.9. I'm only running a 120 Corsair AIO as well which I know isn't ideal at all but my boost clocks are at around 4599MHZ with these adjustments. Thank You!!! Score increased a bit from 14,232 to 14,835

The best CPU Undervolting RU-vid Guide ! Thanks a lot man ))

Great work, really helped me out thanks man

Thank you! You really put a smile on my face when I see The temps on my 5800x now!!!

Thanks for this, great tutorial!

It definitely did help. My PC is running about 10 degrees cooler and running at more mhz on average. My first cinebench r23 test my cpu got up to 100 degrees, and now it doesn't go above 65 degrees during stability test. Thank you for the video!!

Maaan this is great! Thank you!!

Thanks for the detailed guide, man! I was looking for a really long time where curve is buried on the x470 taichi motherboard) But in the end, this option was right in front of my eyes lol

Thanks man, this helped a ton went from 90c in cinebench to being stable at 76-77c

Used the starting numbers you suggested and improved my cinebench score by 300! also got 10 whole degrees cooler from 90 to 80 max temps, thank you sir!

Thanks for the video everyone was talking about this value and the other but they were not explaining the variables that need to be taken into account and that we should do in specific situations

Great tutorial. About 10 degrees lower here, had to be conservative with voltages but its working great!

Used the same settings as you in the MB. Max clock of my cpy (r7 5800x aswel) was 4.8 this made me rally happy. Max temp after running cinebench for 3 hours straight is 76 celcius. This is flikken awesome, especially with summers getting so Hot here

Man this helped me a lot me and my friends are grateful for the hard work you do on this channel, I hope you get recognition cause you deserve it!

this helped a lot, temps dropped from 90 to 76, cinebench score went up as well.

Hands down best guide.. went from high temp to low temp and better boost..

Great walkthrough! I have a 5700x getting 15700 on Cinebench R23. PPT: 140 TDC: 90 EDC: 135 Curve offset: -25 PBO scaler: x5 Max boost CPU: 0mhz Love that I'm able to get 5800x performance :)

great video, thank you

Hey man, thanks so much for this. I have been looking at doing undervolting my 5800x for a while, but your video made me comfortable with it. Especially since I have a gigabyte mainboard! I was able to drop from a max of 84 C to 72C! All this with no real loss of performance. I am also on air cooling Thermalright Peerless Assassin 120.

Thank you! You save my cpu

Thanks a lot. This helped me with the second oven at home called the 5800x inside a NZXT H1

thanks for you experience bro!!!

I’m definitely gonna do this when I get off today. I wonder what temps are gonna be on my 5900x. Again excellent video and great knowledge!!

This is a very good tutorial, easy to follow but I would suggest an addendum with a per core Curve Optimizer and setting up a WEHA Alert in Event Viewer, very easy to do and it'll show you which core is faulting so you can drop that specific core value but keep the other cores up at 30 (or down at 30, as it were). I only suggest this 'cause you explained this perfectly so even a layman could follow and I feel everyone could benefit from you explaining that little extra step in the way that you do. Either way, thank you for this guide, your hard work is appreciated.

Great vid fam

115/70/95 has given me the best balance between minimal loss in performance with huge temp improvements. When I had the EDC higher before, the sustained clocks during heavy loads were significantly worse. My single core clocks still hit 5GHz (using a +150 offset) with lower EDC, despite some people claiming lowering the EDC would hurt single core boost. As far as CO, -5 offset for my 2nd best core, -10 for the "best" one (according to Ryzen Master), -20 for the rest seems stable after 2 days of testing. Not sure why the "best" one survives a better offset, according to many forum posts that shouldn't be the case.

Great videos!

less power usage lower temps with higher clockspeed... occt is the best stress testing app for the cpu i agree! subbed

god bless you and the video. thank u

very fine explaned

Awesome video followed you guide on my 5800x and i had to change the negative 25 to 20 due to it kept giving me errors on OCCT. at negative 20 i ran the OCCT for the whole hour not a single error and ran 5 cinebench all passed with a score of 5910 which is 200 more than what i had at stock which was at 5713

Thank you for this video. It helped me fix a lot of the lag i wa getting when the CPU throttled at high temps. Its ridiculous that the 5800X comes out of the box like this. We shouldn't have to clock our CPUs just so they work as they should. My temps almost halfed by doing this and no issues so far. Thank you.

Thank you so much. My system( ryzen 5800x and asus rog strix b550) was able to use the same settings as yours and runs cooler and all cores hitting 4.650 Ghz.

Great tutorial. I used the values that you set in your bios. My CPU would hit 90.4C on cinebench before under-volt. After the under-volt, it hit an average of 80C. Power consumption went from 136.85 watts to 111 watts. I’m surprised by the temps though since I have a Corsair 240mm aio cooler. The cinebench score went from 15109 to 14954, so there is much to benefit from the under-volt. Thank you

Great work as always boss!! Just upgraded from my 3950x to my new 5900x 3 days ago and immediately went to undervolt after monitoring temps. Was consistently around 84-85c when gaming with 4-8 threads used such as FFXIV or CP77. Used PBO2+Curve and got LUCKY!! All cores -25 offset and fully stable so far after a ton of testing. I could probably do -30 and do per core to change other core values but....nah. Not pushing my luck. Also boosting consistently to 4.95ghz on lighter loads (4 threads) and temps went down to around 77-80c when playing the same games. Used OCCT single core for 30mins on Extreme to test each core for stability as well. All core loads do not have high voltage and thus lower temps (i was already getting only like 70c under full load @4.55ghz). Just like your GPU undervolt guide I used for my EVGA 3080 TI FTW3, this guide was golden. Not getting any WHEA errors at all either as of yet. Tried increasing the clockspeed in PBO2 but whether it was 1-200mhz, PC would reboot. But at least temps are better and avg boost clock is as well. Solid work again boss. Using a Corsair H115i 280mm AIO in a Cooler Master Cosmos C700p case for anyone that wants to know. And my room is always very warm....like 75-80F when the heat is on. Just remember that idle, web browsing and lighter thread loads are where you gotta worry about crashes the most for stability. Not nearly as much for full loads.

Went from 14954 to 15005 higher cinebench score,watts were 142.26w max down to 120.00w, v core 1.504v Max down to 1.488v. core clocks went from jumping all over the place ranging from 37,39,41,42,44 max.the after was every core on same numbers of 4441 practically with a max of 4840.oh I had set the same settings u had 120 75 130 due to having a ryzen 7 myself and wanting to do this for a while. only want to say Ur video helped tremendously most were long confusing, trial an error stuff I didn't even want to try so a big thanks to u best video ever.....

Great guide. Def was not willing to do each core, haha.

Amazing guide man! I took the lazy way and copied your settings. I tried -30 on all cores first, got into windows but it crashed after a few mins, tried -25, cinebench 10 min run crashed with 2 mins left, tried -20 and it passed (this is an 5800x from basically launch so I suppose a core here and there is probably more sensitive to this stuff). So yes while I was super lazy on the stability test I'll continue using it like this and see if crashes in games and stuff, so far my cinebench score improved, OG with auto settings was 15436, after the undervolt it's 15511, but the most insane thing is that my temps dropped from 84c to 74c on full load. (I am on air cooling with a dark rock pro 4)

Temps dropped about 11c. Thank you so much !

Awesome video

best tutorial EVER

A year later and great help went from 86c to 76c on a hyper 212

Thanks bro. I found your video the day I bought my processor. Motherboard, Asus Tuf Gaming b450 plus II. Temperatures in Cinebench dropped from 91 to 80. There is only one caveat, the processor frequency does not exceed 4450, and I still do not know how to increase these frequencies a little without increasing the voltage. I would be glad if someone tells you what value can be changed without raising temperatures in order to slightly increase the frequency.

have u tried the new beta bios? great content. Keep it up :D

YOU ARE THE 🐐

Hello friend, first congratulation for the guide, helped me. I put the same valors at BIOS that video (only antivate xpm). I live in south Spain, now for the test, ambient temperature its 28ºC. Before undervolting, Cinebench R23 (14.186 points): 90ºC, 1.040V-1.472V, 145.61W and 4858MHz. After undervolting, Cinebench R23 (14660 points): 79ºC, 1.160V-1.344V, 113.62W and 4849Mhz. My PC: Ryzen 5800X, motherboard msi MAG X570S TOMAHAWK MAX WIFI, 16Gb DDR4 3200Mhz G.SKILL, XFX 309 (RX 6700XT), NZXT Kraken Z63, paste Noctua, M.2 Kingston Fury Renegade 1TB 4.0 NVMe.

I used your values, I was getting 90c in Cinebench and 4.5ghz top. Now never goes above 78c in Cinebench test up to 4.7ghz. Performance increased about 110 points. Works great thank you.

Thank you so much, man! Came here after watching the GPU undervolt guide (which was really helpful). Hope this works as well.

nice, man

This is gold

Used this last night on my setup. 4070ti, b550 auros elite mob, Kingston fury 32gb ram. I’ve recently upgraded the case to a hyte y40 and since then the temps have been all over the place. Went with your exact undervolt and the pc is running about 17-20 degrees cooler even whilst gaming! Thanks for the video

Hello! Thanks for the tutorial. In my case the temps didn't drop much. I don't mind losing some performance since the heavy tasks of my pc are made by the GPU, so what do you recommend for lowering the temps a bit more?

I just wanna say i’m the least reliable when it comes to Bios settings. And Oh my god…. copy pasted your settings. Adjusted small things on the amounts and the results are phenomenal. I cut from 90C at all times when playing games on any setting and Went to 81C max. My idle went from 55s to 35s. Better clock speeds, lower temps. Thank you king😤

It works. I have 22k with a 5950x using Cinebench in 2024 with tops temps in the 40s.

From 90.3C to 79.3C on average, have been tested for 3 days now and it seems to be solid. Thanks a lot!!

Thanks for the video! Seems they rolled it out for B400 Motherboards as well. I have a MSI b450 pro carbon ac with the 5800x and with 120 85 30 / -25 I get max temp 76 C, with a Silent Assassin air cooler and 15227 in R23.

I'm currently waiting for my new build to get here so I can build it lol it is going to have an AIO but I will start stock before undervolt just to have something to compare my results with . Also have an xfx speedster zero wb 6900xt which I may attempt afterwards .

Hey boss, just used your video to undervolt my x5800. Quick question, with these settings have you had any crashes while idling?

Thank you so much! this video helped solve my psu issue. 5800x with b550 mb, my cpu temp was higher then i wanted it to be while gaming with 2tabs on the second monitor 70-80c while gaming. followed your instructions other then PBO limits to disabled, all cores -30 did same gaming stress got roughly 10+ fps but the difference in the temp 58-72c Thanks again!

Tip for those with an air cooler like me, set your cpu core frequency to 4.4 ghz(4400 mhz) instead of auto and your max temp should be 72 C. If you’ll leave it on auto you’ll get around 4.6 in the video, so you’ll only lose 200 mhz of speed which is a very small difference, you will not notice it. Otherwise you may get over 80 C like I did which if you don’t know you do not want your cpu ever over 80 C because it’ll cause long term damage to the cpus silicone. Solid video guide btw

Great video! Dumb question: How in the world do you get notepad to be dark grey like that instead of bright white?

Wooow really thanks man 👍🏻 i go from 87° in pressure to 70° !!! wow really, but what if i want increase performance with a little increase of temps, do i have to increase numbers like i go with 130, 85, 140 ... or decrease it or what

Hello, nice video. I did exactly the same settings on bios except i put "25" negative on my 5800x that sits on b450 aorus pro motherboard. I tested cinebench after but i didn't let it finish because cpu was hitting 90C+ at 4800mhz. Compared to this video i was scared so i stopped it. What might be the problem if it is problem anyway? Thanks edit: reverted to default settings and this time i get same temps around 90C degrees but clocks are lower at 4450-4500mhz.

Air Cooled 5800x CPU Stock: 14110; PBO On: 14497; PBO2 & Curve: 15122. ~10 C drop. PPT = 120; EDC = 110; TDC = 75; Curve Optimizer = 10. 7.17% increase in score. Thanks.

Thank you!! I watched your GPU undervolt video and that helped me a ton keeping the temps on my 3080 Ti under control and this video definitely helped me undervolt my 5900x

Can you make a video how u set up rivatuner clean like that? thanks dude.. very good video

Update since the last post - My 5800X is OC locked at 4.4 Ghz in the CPU Core Ratio with Voltage set to Auto Negative Offset. Running Cinebench, CPU doesn't go past 71 deg with a 240 AIO. Power usage is significantly rrduced too. I don't recall what my multi-core score was but I think it was in the 19,000s. My 5900X set to 4.5 Ghz with the same undervolting gets a score about 24,000 if memory serves with temps never going about 74 deg on a 120 AIO with a Phanteks T30x120 fan. Edit to the update 3/26/2024 - I just ran a new install of Cinebench R23 on this Ryzen7 5800X, and the multi-core score was 14,672 with the aforementioned OC locked at 4.4 Ghz. Temperatures never went above 67 deg, and used only 1.1V the entire time. Not too shabby.

My 5900X was doing 70°C on air (dark rock pro 4) without any PBO. Got into PBO, raised a couple limits, undervolted my cores per core by their quality (HWINFO64 tells you which cores are the best to worse) and raised 75mhz the max boost clock with boost override. Now my system does 73°C max but my scores and clocks raised by quite a bit (from 4.3ghz to 4.5ghz all core boost in cinebench and single core from 4.9ghz to 5.05ghz and from 21.300 score to 22.800) also got better FPS in games. I believe that's a win.

Saw this video on my suggestions as i love undervolting , thanks for the pointer on OCCT , its great Obviously i subscribed as you seem to have a great channel but that music, it distracts from your lovely voice , Im English so could listen to you read a phone book (you're too young to remember them) and still be riveted

Damn, just went from 70c average on heavy game workloads to 55c with my 5900x. Now I can enjoy VR with less heat before the summer gets here LOL liked and subbed!!

Great video following your settings my 5800X in a NZXT N1 I never went over 67c

Hey wilcreatives was wondering since am new to all this undervolting is it better to use pbo2 tuner or go in bios and change my overdrive to negative -30 on all cores?

Have you tried all core Oc on this setup ? Any diff with results ? Tx

Great tutorial, thank you. Absolutely the worst music I've ever heard in a video though. Just rage inducing.

I have Scythen Fuma 2 with this CPU. Do you recommend liquid cooling?

From 90°C max temps to 78°C max temps with a loss of 300 points in multicore score. Worth it while I get better cooling and a case with better airflow.

Wow!! I just built my first PC and I was really scared of the temps. Before I hit 90°C all the time with 91°C peak. After copying your exact settings it runs way cooler and I top at 81.5 so thats almost 10 degrees less. and the best part... I even gained Performance! I used the 3dmark cpu bench and I actually went from 7760 to 7852. I'd give this 1000 thumbs up. I can sleep better now knowing my CPU is running nice and warm.

Hey man.. so I went through your guide have about the same exact settings but have a couple problems.. 1. When I choose the MHz for the fclk I'm crashing in cinebench. 2. I'm only seeing MAX 80W on my Power>Cores section on CPUID shouldn't this be 120W? I feel like I should have more out of this without being so unstable? when stable I'm only getting around 14000 even less than the "Compared to" system. Any ideas? Thanks man for making this video!

What does setting pbo limit to auto do compared to choosing manual and typing in the default limits?

Just slapped your settings in on my rig. I dropped 20c! Which awesome it keeps my 4090 5c colder and keeps fan noise down!.

Great Guide. Finally getting around to this since I want better performance so I don't get TOO tempted to by a 7000 series right off the bat. I bought this 5800x for $449 and now I see the $240 5700x and I'm like did I really need to be a super early adopter on this gen haha

I was VERY scared to touch anything but I tried it cause of you and how confident you made me feel thank you seriously but where can I ask questions?

Great Tutorial. I was able to increase Cinebench clocks from 4250 to 4500, but ended up limiting power to 115, which ends up limiting to around 106, because I am only running a Hyper 212 Evo and want to keep temps under 80C if doing video encodes, and am fine with a minor performance hit. So 4350MHz @ 106W is fine for me on 5800x, -25 ticks stable.

This is a must, I was hitting 91 Celsius on my 3900x on the Wraith Prism at max load with a cinebench score of 16k, now I have undervolted to 1.25v and hitting just under 90 but the cinebench R23 score has increased to just over 18k, that's a massive difference.

the temp drop is wild

Works amazing man went from 76 to 70 to 60 with -25 ima try 30 might work better

Yeah I just bought my 1st Ryzen 5 5600x since ASUS finally added support for my Asus rog strix b350-f gaming mobo in the bios release for May 2022 I flashed my mobo to the latest bios enabled PBO 2.0 went into advance set it to motherboard everything else I left it in auto I didn't mess with the curve optimizer I disabled it. Booted up my pc and my cpu automatically boosts to 4.7ghz just enabling PBO wow. I get a score of 106% for my specific cpu on userbenchmark UFO!!!

I built a Ryzen 7 5800X a few months ago, and it's been running below 60*C while playing Halo Infinite, and near 70*C while running Cinebench 23. My other PC I built 2 weeks ago runs a Ryzen 9 5900X, and she runs hot. While playing Halo Infinite, it peaks at 81*C, and running Cinebench 23, it has only peaked at 78*C. The 5900X is the one I would like to try undervolting to get the temperatures down. Both system are cooled by Cooler Master 240mm AIO. with 3 intake fans, and 3 exhaust fans. These temperatures are in a 21*C (70*F) room. What should I do on the Asus Prime X570-Pro motherboard to undervolt the 5900X?

probs a dumb question but if that all fails can you use "load default" to undo all the stuff you did? im a 5800x user my temps are normally under 70 degrees in all games i play but recently they have been going up to 83 degrees not sure why. thanks

I set everything the same but the curve optimizer which i set to -30 and run occt it gave me WHEA error(searched on the internet this basically means you need to put +10/+20w more to your cpu) than i tried the curve optimizer at -25 like you did no errors at all ty ❤

I really thankful for your video bro! i bought ryzen 7 5800x yesterday and im playing games always got me like 80-90 celcius but after followed your guide the temperature is decrease by 10 celcius now! thanks a lot bro! edit: after 1 day my temp going back again at 90c... can you help me sir? i already try undervolting it but still gets 90c

The 5800X intentionally ramps up the clocks until the Tctl/die temp hits 90°C, unless the CPU hits one of the other limits first. This is by design, and does not mean that the CPU is running too hot. That's how it is supposed to work. I can understand that some people are uncomfortable with those temps, but AMD says that that is how the CPU is designed to work. If you want to lower the temps anyway, some motherboard have an ECO mode, and some have PBO presets that limit the wattage. Just try those settings, or lower PPT. Curve Optimizer is not designed to limit temperatures. It's designed to allow you to under-volt the CPU, which results in higher clock speeds at the same temperatures. Just set PBO to Manual, leave everything in Auto, and use negative values in Curve Optimizer to under-volt the CPU - experiment with the setting to find your maximum stable setting. You'll see a slight increase in your clock speeds at the same temperatures.
