Ryzen 5800x Undervolt Bios Settings 

To help with stress testing on OCCT I have uploaded this video to show both single core and multi core tests. This should help check for a stable undervolt. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-77zBduI09gY.html

You are LEGENDARY for this. I went down 10-14 degrees and my Cinebench score stayed the same but instead of throttling three times it chilled at 75-79 on like the sixth test. Had i tried that with normal settings it would be chilling at 90 halfway through the second go. For an open air case and 240mm aio I’m overjoyed. THANK YOU.

Perfect! I replaced my Aio with a Corsair 360 and was still running high 80s when max load. Used your settings and dropped to 78 and a consistent 4.7ghz through an entire cinebench run! Thank you so much!

Excellent video! Just completed my 5800x build, and was shocked to see it shooting into the redzone in HWiNFO. 85c-to 90c, at stock clocks while running Cinebench, even hitting 70c just installing games! Befuddling, especially, because I'm running a new EK AIO 360mm with Thermal Grizzly TIM.. Short of a custom open loop, just about as good as it gets! So, naturally. I re-seated the waterblock, twice. Same result... Damn. But a quick browse, and I see I'm not alone. This tutorial has brought it to acceptable levels. Dropped a solid 10c across the board! Thanks!

Amazing video! Thank you so much. I noticed a drastic reduction in temps with a modest performance boost. Amazing video for anyone who just installed a 5800x.

Thank you so much for the video! It works, although I still get 81 in R23 cinebench but it was a significant reduce in temp with little tweaks and also getting more juice out of it! Highly recommended

Hey it worked for me! I used my pc for a week with these settings and my temps went down from 85° to 79 max en cinebench! thank you.

I’ve got the same cpu and the same motherboard so I was able to follow this guide pretty exactly. I’ve also got an AIO for my CPU. Just by changing those values to the ones you had I’ve gone from low 80’s usually boosting around 4.4ghz to high 60’s or low 70’s at 4.5ghz. This guide is kinda cracked thanks a bunch

To this day this is the only video I recommend to people for this process. Short and sweet and amazing results. Thank you!

Mate I've gotta thankyou for this video, dropped my temps from 90c all core cinebench r20 down to 77c, and ended up with almost 200mhz higher all core as well. Great advice, especially for people with a 5800x in a small case.

luckily I'm using same mobo and processor so I just copied those settings over and its been great. idle Temps went from 63 to 40 and full work load from 84 to 73. single core boost goes up to around 4.9ghz. definitely loving how much more efficient this is running with more reasonable thermals. great video with great info. thank you so much!

Man, you are literally a legend. I had heat issues with my R7 5700X too (in a B550 Aorus Elite V2 mobo), got 90 degrees under Cinebench and it always throttled to 4,5 ghz under benchmarking, etc. These undervolt settings just made my cpu so much better, that i seriously can't believe. Under Cinebench now, it barely goes over 75-77 degrees, and it's sitting now stable on 4,8ghz, during the 10 minutes throttling test, man, it's just fckn unbelievable!! Thank you sooo much for this blessing of guide, wishing you all the best from Hungary!!

I’m not a benchmark guy but I used the settings you listed in the video on my asus tuf x570 and they lowered my idle temps from 45 to 50c down to 36 to 38c and my gaming temps from 66 to 72c down to 60 to 64c with an AIO 280mm. Very pleased. Thank you!!

Yo your a god. Hit 86c in r23 before. Copied your settings and highest I saw was 75c and hit 4.85 which is crazy huge help ty 🙏

Hey dude I copied your settings for my PC and my temps went from 80 to 69(nice) it also remains at a good frequency with same and sometimes better performance . Thank you very much for this video.

Really thanks for this info and tests. I've finally exited from eco mode /65w to an excellent 5800x cpu configuration 👍

Thank you! Thing was throttling under a nice tower cooler and couldn't figure out why, this has fixed all stability and temperature issues.

Really appreciate your work on this, my ASUS was the same - It was only in the 2nd location the PBO settings took! Thank you, this really helped me understand a good place to start experimenting with the right values.

Thank you, my mates and me did this but never found a useful video about it! Cheers

Helped me by around 10c, definitely running better. Thank you for this!

Thank you so much. Drop 10 degrees with your undervolt setting. Very helpful for my itx build. Was hitting 82 before with cinebench multi core test.

I literally dropped 10 degrees overall and got better performance by applying your final settings!! Cinebench went from 14261 to 14584 on multicore test, max power draw during benchmark went from 142.26w to 120.20w and the CPU package temps went from 80.5° to 71.5° during the benchmark. The overall clock speeds got also higher! All cores were hitting over 4800mHz while before at least 3 of the cores were staying bellow 4800mHz! The Idle power draw went from 46w to 44w with temps going from ~50,55° idle to ~40,45° when browsing with chrome. If I kill all background apps and system tray processes, my idle temp can dip below 40°!!! I haven't even played around with the settings to find my own values. THAT'S INSANE!!! Bro you are GOATED!!!!

I dropped like 15 degrees and got from 4.5 mhz to almost 4.7. Great video. Thank you!

Thank you so much for this guide. Simple and right to the point and worked like a charm. Cheers

My 5800x has been spicy for the last year. Been wanting to do something about it but other guides were so long and convoluted. I have a similar Asus board to you so I just plugged in your numbers and did a cinebench run. Temps down from 89 to 80, and all core boost up from 4.4 to 4.55! Thank you!!! Will do some stability testing soon and maybe tweak a bit more.

Words can not express how much of a blessing this guide was. The 5800x has been a thorn in my side since I bought it. My idle temps ranged from 40C - 60C, it was thermal throttling in cinebench, gamed around +80C, and my AIO sounded like it was blasting off into orbit all the time. I was beginning to think I got a lemon, it probably is, lol. These were my scores in cinebench before the tweaks(best run without obvious throttling): 15180 multi-core / max temp 87C 1599 single-core / max temp 68C And after: 15424 (+/-50) multi-core / max temp 71C 1595 single-core / max temp 58C(only did one pass since single core takes so long to render) These worked best for me, but I might play around with the PPT limit a little more in the future (I'm also using a MSI motherboard if that means anything to anyone): PPT limit (W) 125 TDC limit (A) 85 EDC (A) 130 curve magnitude 30 If you're having a hard time finding these look for the PBO settings (Precision Boost Overdrive) should be in the AMD CPU overclocking options. Pro tip: you can make changes to the PPT, TDC, and EDC while in windows through Ryzen Master while you're testing. Unfortunately, I didn't see an option to adjust the curve magnitude outside of bios, you still have to plug them into bios once you've found your sweet spot. Also, I fired up BF2042 the heaviest game on the CPU I've got and that never went above 72C after two matches. I can also idle in the 30s now. **A (not so) Quick Update, I figured out what accounted for 50% of my temperature loss. I'm new to AIOs and my bios won't save my pump speed so I needed a program to set it in Windows. (I later realized it wasn't how long the water stayed in the rad but that the pumps default speed was so low it caused the pump to misbehave. The faster the pump runs the cooler it'll make the component.) Of course, I didn't notice the affect at the time, because like an idiot, I changed it on a whim while changing multiple settings at the same time. Figured I should share this in case someone reading has a similar situation it's something else you can check instead of just kneecapping your performance if it's a contributor. I think it's also important to note what PPT, TDC, and EDC are to make your tuning process go a little smoother. If your goal is to lower your temps under load TDC is the value you should lower first (it defaults at 95); under a sustained load during the ten minute multi-core run in cinebench will do. TDC governs the amount of power (current) used continuously under load. The EDC governs the total power (current) available for the chips boost, you don't have to set this below default (140) if you don't want to. PPT determents the total power (wattage) available to I think just the cores but it could be the whole chip. You also don't have to lower this below its default (142). In summery, just lower PPT and EDC after you set the TDC to your liking, in increments of 5 until your average frequency drops and step it to a number just above. Doing this in Ryzen Master will save you a TON of time. Literally, after learning the layout tuning with Ryzen Master will take less than ten minutes. So much for a "quick update", I just thought sharing this will let someone get everything squared away, instead of the days it took me to fully understand what compounded my thermal issue with a solution that's better than just kneecapping your performance.

Seeing an incredible drop of 10C down from 84C under load, after mucking around a bit within the parameters you outlined (video settings wouldn’t boot into windows, just kept cycling to BIOS), has absolutely made me much happier. Fan speeds are in control, and more importantly, cooler temps in my office! TUF X570 Plus. Had to bring negative cpu optimizer value down from 30 to 10 to boot into windows. Works perfectly now! Thanks!!

Straight to the point, clear instructions. MVP!

Thank you, thank you, thank you - this was great, I had weird issues with my CPU - turns out my firmware settings where abysmal. The setting you showed helped me lower the temps and get the computer running great.

Directly copying these settings on the same hardware dropped my idle voltage draw from 1.450 to 1.300. Temps are 10-15c lower across the board under load and 20+ idle. Thank you for this it was literally an oven.

This was a very helpful video, even two years after posting. I was able to shave 12C off my full-load temp, bringing me to a comfortable 77C. All while clocking 4775 and 4825 consistently. Thank you for the easy to follow guide. Undervolting was 100% worth it and saved me about 160ish USD now that I'm not looking to buy an AIO anymore. An hour long Battlefield 2042 session @1440/144 ultra settings and I didn't even hit 80C. I'd say that's definitely a win. I'm using a Cooler Master Hyper 212 (tower-fan) if that info helps anyone. Fan+undervolt can save you a good chunk of money that you can put towards other components. Best wishes!

Greatly appreciated, max 92 dropped to 77 degrees and cinebench results went up which is just awesome. This vid actually saved me from buying a new cpu cooler.

I followed the instructions and it worked so nice! Thanks so much!

Thanks so much for this. I had been seeing 85-90C gaming/heavy loads even with a custom EK water cooling loop. Running P95 small FFT's I peaked at just 77C, I finally feel like have my 5800X's temps under control.

Thank you, didnt use Cinebench to see the difference, but in Witcher 3, CPU temps dropped about 10°.

Dude! You are superior. Thanks for the all info that you gave us.

Really thank you very much! Temps dropped on cinebench about 10c from 90 to 80!

Went down from 84°C to 75°C at the AIDA64 stress test with a masterliquid ml240. So useful, thanks for the video, definitely the best one out there!

My results also mirrored most people's that tried this. With PPT 120, TDC 85, EDC 130 but with the curve set to NEGATIVE 10 (as 20 & 30 were unstable) my IDLE/GAMING CPU temps are easily 10-15°C cooler. I don't test with Cinebench although I do have it, but this means I can now fold using my CPU on 1 core and no longer hit 90°, but 80 which is still a bit toasty for my liking. Thanks for making such a great tutorial.

2 años desde que subiste tu video y sigues ayudando! Muchas gracias. Antes de tu video estaba sufriendo de una inestabilidad terrible en mi cpu y con tus parámetros no solo he notado una estabilidad tremenda en los juegos sino que las temperaturas han mejorado. Una vez más, muchas gracias!

Thx soo mich I searched for days and finally found your video explaining how it properly workes Got a performance increase from 12000 points to 13093 in cinebench and a temp drop of 4°C 👍🏼

Thank you very much! My Ryzen 5800X temperatures dropped 10 degrees. Now it is Max 70°C under full load with 4.65 GHz on all cores. My settings: 120/75/130 and -30 on all cores.

Thank you! my temperatures dropped 10 degrees. It is strange because I have never had problems with temperatures but with each update of the bios these have risen constantly until with the last update I have reached 90 ° with a cinebench. What bothers me a bit is that previously I was doing over 6000 points on the R20, but now I get the result I had before without undervolt with PBO at -30, about 5800 points. These are synthetic tests so no tangible difference in real life but still!

Thank u so much, this helped me a lot, I was really sad about my 5800x's temps.

amazing, just what I needed, down ten degrees, and increased performance. thx ..

This is incredible! I have a new 5800x that was running at 91 degrees under load, with a 240mm AIO. Following these instructions dropped my temps by 11 degrees, and my cinebench scores went up about 10%. You are a genius.

Wow! I used your settings of PPT-120 TDC-85 TDC-130 with a All core -10 curb and I got 8c less!!!!! great work. System specs are 5800x - Asus TUF x570WiFi - DDR4-3600Mhz ---14-14-14-34@1.45v

Thank you! Thank you! Thank you! Increased my Cincebench scores by 1,000 points and dropped my temps by 10 degrees!

Its works many thanks from austria ❤️ From 83 to 72 with noctua nh15 pro Thank you

Dude your the best , copied your settings, dropped 15 degrees, now sitting at 75 degrees at 100% load on r23 multi core test, completely stable. Legend

Thanks for this video! I tried your settings CPU temps was at 85 in Cinebench 55 idle. Now my temps are 71 in Cinebench with 38 idle and boosted Cinebench score by ~700pts.

Even after 2 years, thanks to your post I could cut 12% temperature on my MSI B550 A Pro motherboard. From 90 to 78 while doing the synthetize stabilization in Premiere Pro. Thank you!

Thank you for this bud! Decreased temps and increased performance just like you said! Sub and a like!

OMG liked and subscribed! Just built my dream PC with the R7 5800X but noticed CPU temps were pretty warm (85-90) playing Cyberpunk for example. Watched a few videos on undervolting but was confused on how to do it with my Asus x570i mobo but luckily stumbled on your video, copied your settings, and now my temps are 75-80!! 10 degree difference WOW thank you so much :-) EDIT: i tried benchmarking and crashed, so i tried the alternate settings you recommended and it benchmarked flawlessly!! you might consider adding “x570” to the title to get more views from noobs like me

Wow this saved me a trip to return the chip to best buy. I originally hit 90.C deg on cinebench r23. When I applied it to bios I peaked at 79.C but now run a stable 78.C under 100% workload. I did this on a b450 aorus m

Bro tysm. My temps are immaculate now. Went from playing red dead 2 on 75-80 to now being on 55. Great Video mate 👍

Perfect!!🔥 Incredible drop of temperature. Under stress going up to 73 degrees maximum 💥

Duuude I went from hitting 83c to an average of 70 while playing Jedi Fallen Order, thank you so much!!! God bless.

Thank you. My idling temps were 80 degrees Celsius. Now heavy loads are 60 thank you

Thank you so much ! Incredible best result on cinebench 👍

Amazing! used the same setting getting 65 - 70deg in cinebench MC and 30deg idle plus it still boosts to 4.7ghz 👍🏾

Omg this actually worked! My CPU dropped about 10C while playing Warzone and I had better FPS! Cheers mate!

Also works on Aorus B550 Elite AX V2. Ryzen 5600X. I set PBO limits to disabled. Curve at negative 25. Massively reduced temperatures same boost clock speeds

Finally a no nonsense quick vid, thanks bro

Thanks, this fixed my 90c temperature problem! :)

Thanks for sharing! I have 5800x running on B550-A with Kraken X63 AIO. My multicore score in Cinebench R23 went from 13,858 to 14,852 and single core went from 1,532 to 1585 using your final settings. Temperature went from 87C to 77C.

Cinebench temps went from 87c to 73c. Using a custom loop with a corsair xr5 360mm rad and ek velocity block. I didn’t expect much with the results since I am using my old Prime X470 Pro but now i am very happy. Also nice that I had the exact same bios layout so your demonstration was very easy to follow Thanks a bunch!

Thank You so much for this video. Settings worked great on my ryzen 5 5600 non X. Running stresstest now see if it is stable. After 10 min my cpu sitting at 58C before the settings after 5 mun it was at 72C. I hope it will be stable. I even added 100mhz to the processor override. TY Alot.

Thank you so much! This was my first time doing any form of CPU tweaking. My 5800x was running at a max temperature of 90°C (ugh) and I copied your settings at the end of the video. The full load temperatures (multi-core) went down to 80°C and my Cinebench score actually improved slightly by 464 points.

I used your settings for an MSI mpg b550 gaming and dropped my temps also. I just built this was used to intel coming from a 6700k to 5800x what a curve to learn. I'm used to temps never getting over 55c but when I updated bios the temps at idle are 4c or higher and cinabench r23 what hitting 82c now I'm at 72c at cinabench.. I'm stressed out over this temp thing. I even reseated and reapply thermal.

ODD question, I was looking at my clock speeds when playing a game with hwinfo and noticed it only went to 4.6 even with pbo on and asus performance enhancer on "OC", did your settings and while gaming I get a constant 4.8 or 4.825 now with way lower temps??? I'm so confused why this is so good and allows me to get higher clocks during gameplay. I have the same motherboard and an aio so temps never really mattered but I've never seen a 4.8 unless I was doing something other than gaming before this.

Thank you!! I’ve been strugling with my temps on the 5800x forever. Used to get 47-55 C on idle and this just got me on 37C

Only lowered my idle temp by about 5C but lowered my gaming temp by about 12C. Your a scholar and a saint!

Dropped my 5800X from 89C under custom water cooling to 73C in cinebench testing while also increasing all core clock by 150Mhz

Thanks have the same MOBO and CPU made my life easier. I have NZXT 360 AIO and temps were running so high stock 85-90 full load and idle at 50-60 on like 8% load. I went from 120/75/130 63 degrees on cinebench r32 but performance decreased I’ll try your exact settings and see value.

Awesome and informative video! My 5800x is stable as can be Thanks to this video! 🙏🏾 Blessings!

this actually worked as described! thanks!

I have different settings; and I run Cinebench at 55 degrees max on my 5600X PBO - Advanced PBO Limits - Disabled PBO Scalar - Auto Curve Optimizer - All cores All Core Optimizer Sign - Negative All Core Optimizer Magnitude - 30 High performance, Low Temps :)

Helpful video! I used your settings, but can only hit negative 10 on the curve optimizer or the PC crashes. Still, it reduced my temps from 91C to 80C while running Cinebench. Tho all-core boost is also a bit lower now at around 4.5 GHz, single core can hit 5.05 GHz on one core and 5 GHz on three more. AMD says that temps of 90C are "working as designed" tho.

Thanks so much! These settings worked a treat. Though 20 seems to be the sweet spot for me under Curve Optimizer.

Thank you .. My settings: 120/75/130 and -30 on all cores. works great for me

Here are my results, I have a 120MM AIO (I originally expected a 5600x, but I instead got a 5800x, hence the small AIO): Base clock: Cinebench23 Multi core score: 14040, 90c capped C23 Single score: 1514, 78-80c single Undervolted: C23 Multi: 15012 (+7%), temp: 88-90c (takes a couple mins to reach 90c) C23 Single: 1586 (+5%), temp: 73c (-7c) I could probably squeeze a bit more performance on the multi core test if I get a proper cooling solution, but this is definitely a great result, thanks!

Bro you are a legend. Cinebench R23 went from 84-86 down to 75 degrees.Thats 10 degrees lower with 4,525ghz with PPT: 120 TDC: 85 and EDC: 130

Fantastic, been panicking at my temps even with new Thermal Grizzly paste. Was idling at around 55C with a Coolermaster 360 AIO, now down to 37C. Cheers SIr, you're a star!!!😁

Amazing!! Did this on my 5800X, Tuf X570 plus, and a noctua u12S Chromax Black air cooler. I am running high 30's at idle now and as I only play Microsoft Flight Simulator, I am staying around 57C on average where I was at about 70C before the undervolt. Well done and thank you!!

Make sure to test single thread for cinebench as well. Lots of people get.instability from doing an all core negative offset since not all cores are equal, and some require more voltage to remain stable. For example, you could be fine with a negative 20+ offset for all core, but for single core, you may only be able to get away with negative 18.

Why the 5800x cpus are s hot on default settings, without tweaking? Thanks for the guide though

Thank you. At 120/85/130 and curve negative 25 = 4.6Ghz. Before 75° now 65° and Cinebench 14,981 points. good job!

This is such a great video - especially since I have an Asus board. I was going to leave it like it was - 90c under heavy load - 86ish gaming - but then I thought, why not. Maybe it wont take all day. It took 20 mins. For those of you wondering, the comment from @SkewedDetails about using Ryzen Master to get the values while running Cinebench was a life saver - it will save you 100 reboots :) - Literally did all this in 20 mins and went from 4.5Mhz PBO sustained and 89-90c-ish during load to almost 4.7Mhz sustained and 75c during load now. Thank you!! My values were PPT 125 TDC 76 EDC 125 Neg Curve Magnitude is 20 - I tried 30 and it booted but then crashed when trying to load cinebench. I do not think I will try to get more precise than this as I am happy with the result with 20 mins of work :)

After additional experiments, I have the following settings and improved results: 120/85/130 and -30 on all cores. Max CPU Boost Clock Override - 200Mhz. Single-core performance: 5050 MHz. Multicore under full load (Visual Studio project compilation) performance on all cores: ~4850 MHz. This is a great result for me. Room temp is 25°C. Max 70°C under full load and 40°C - 45°C in idle mode. Cooling: Corsair Hydro Series H80i v2.

you improved my cinebench score by over 500, and dropped my max temp from 90 to 75. Damn.

Very good video. Easy to understand. Thank you.

unbelievable. dropped 13 degrees when use your settings. from 89.5 to 76.8. very much thanks :) hopefully the system will be stable

My current settings for 5800X PPT - 185W TDC - 125A EDC - 170A PBO Scalar - 10X Max CPU Boost Clock Override - 200Mhz Negative offset -25 all cores (except 2 of strong cores from Ryzen master -15)

Mine runs at 67 degrees max, let me try these settings and see if it lowers the temp. Edit: after copying these exact settings I'm now running at 57 degrees max 🙏

Wow thank you! Going to give this a shot.

This works mate i set your same values with curve magnitude of 20 and i doped about 6 degrees which is good. Previous was 90 degrees and now a stable 4.5 ghz

Damn, my cpu temps dropped from 75c to 65c with zero affect on performance. Kinda disappointed how unoptimized the 5800x runs at default.

Very helpful tutorial! Well done and many thanks! On my ASUS "ROG Strix B550A Gaming" motherboard w/ the R7 5800X, I set the DOHCP (XMP) profile and applied the Curve Optimization method, per your video. I did note that there was no ALL CORE choice for the Curve Optimzation selection, so I left in AUTO and selected the NEGATIVE from the subordinate menu selection. It would not allow me to go above 25 (negative), so the targeted 30 seems to be off the table. In any event, I went a more conservative PPT 120/TDC 75/EDC 130 for the other settings under Manual PBO Limits. Seems that with a dual 120mm SNOWMAN (6x6mm) air cooler, temps max at 80C with 25C ambient, which is fine. CB R23 all core topped out at 14,150pts and system is stable. I suppose I could up the cooling solution with an AIO to further improve CBR23 performance, but the current performance is OK for our use case. Again, many thanks!

Thanks so much.. new to pc building and was having problems with temps bouncing off 90°c for the whole run and mis 50s to mid 60s at idle after moving this processor from an a320m-k to a b550-f with the same aio 240 and thus was my solution. Now idle in high 30s with the test never seeing above 72
