Should You Undervolt Your CPU?
HTML-код
- Опубликовано: 7 апр 2024
- We tried a mild automatic overclock last week and this week we are going to try to see how far we can go with undervolting. Then we will see how well it performs. Will undervolting lower the CPU temperature and power usage and give more performance while doing it?

Thats such a neat software, kicks the ass out of bios tweaking and 3rd party stress testing
Dude, your intro song is so awesome
Thanks for posting this one is definitely a pearl of wisdom worth bookmarking to check back with for future reference, undervolting and slightly downclocking can also give you extra performance as if done right the CPU will never thermal or power throttle, for team red it looks a lot less work than using throttle-stop to get the absolute best out of the intels.... for example I had an 8750h that had a truly massive undervolt on the core - 325mV but only got -125mV on the cache, a cpu which used to throttle at around 105c would stay at around 74c even playing Star Citizen for hours! it was worth running it 200mhZ below max clock to save its life through the last hot summer lol... all I need to do now seek out a tool that I can trust and will work with AMD 7xxx series laptop cpus..
Great video, When using Ryzen Master to tweaks settings, do you need to have the bios set to default first ?
Love the channel. Do we need to reset the bios as I have a curve optimiser undervolt in the bios, before trying this out?
Undervolting is amazing to save power and lower temps. I undervolted just 0.25 V and saved like 50% power.
Just .25 V? 250 mV is a ton!
I'm not even going past around -100mv
.25 V is 250mV
I leave PBO auto in bios and I’d check out these vids but I only hit 60c max @ 4.65 in all games at 1440p 144. Hyper212EVO DARK cooler in cooler master H500 mesh case.
Mine doesn't have a manual mode. Only thing I can do is change settings in BIOS.
👍 tGreat Video. Me and my Ryzen thank you
Great video. I've recently moved over from Intel and got myself a ryzen 7 7800x3d. Trying to follow along with you as I assume it should still work but I don't see a 'manual' tab in Ryzen Master under any of the profile pages. Am I doing something wrong or doesn't this apply to the 7800? Really appreciate any help.
My Ryzen 9 5950x on a B550, 128gb ddr5 is down 20w and 10 degrees so far.. Probably could have taken it down further.. but dropped it to: peak core: .953741 and CPU lost 38w. That's some good savings. Now I'll see what difference it made to my nicehash mining. Rebooted and CPU is doing great. Getting 14.0772KH/s Love this CPU. Paid $900 used, but it's always been an awesome workhorse.
heres a vid idea
as ive been in the tech prob as long as you
compare chrome to firefox as with your chipset vid some things just hardcore about doing...
@careyholzman recently made a similar video about how motherboard manufacturers are setting the default values so that CPUs are basically overclocked and how they should be set to the CPU recommended settings
I wish there were such a simple solution (software) for Linux. By simple I mean easy to install and use…I played with this on Windows and I’m glad to have this map for using it! One of the most valuable insights I got, just banging away at it was that 3 of the cores on my R9 7900x are much sweeter that the rest, and therefore are used considerably harder. I guess that’s configured by the onboard firmware and BIOS? I wonder if it would profit the system overall to bias the other cores slightly higher to spread the load out a bit more?
My other main insight was that there’s a lot more going on here than I can easily appreciate!
Does Ryzen Master still not load if you have a hypervisor active on your system?
I had problem when trying to undervolt my laptop ROG STRIX SCAR 17 Ryzen 9 7945HX with RTX 4090 laptop
Every time when I was changing the value - it didn't matter, -5, -10, -15 and so on the laptop would do restart and that undervolt woukd reset. I was trying with G-helper, UXTU
Doing the same straight in bios - it worked.
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. My cpu on idle ( 60°C ) and under load ( 100°C ) went to 25°C on idle and 60°C under load . Hope this helped ❤❤❤❤
Can this be applied to switch on (not for gaming)when doing regular computing when the cpu is under load? Then when not underload go back to idle? I have an i7 10700 thx
do you have a video for intel cpu
Wouldn’t it be a pretty similar process - but what software would you use? Or would you have to use BIOS settings and continually reboot? I wonder if Intel has the voltage feature locked down….
@@TSPhotoAtlanta Yes indeed, you do it in the bios and there you can also tweak locked CPUs, at least I can with my Asus Z690 motherboard.
dang, unto the ripple zone.
Hi, tying out Ryzen Master 1st try, however my menu does not show me the option for MANUL for overclocking. I did disable Precision boost, set to Disabled. wonding if the latest version eliminates this option ? what is the version you used ?
Same here
If your gaming on 14.th gen underclock singlecore slightly and run all core oc instead. Cpu becomes so much easier too cool and no throttling issues. Gives way better framepacing in games too.
Im curious could you also do the curve optimization with this and get even cooler performance and maybe a performance increase? I have a 5900x with curve optimization at -30 which decreased my temps and improved performance but could it still be undervolted to make it run even cooler?
you mean with pbo tuner?, i've used that aswell when my 5800x3d was brand new, it worked good for testing how you land +- (@ ... frequentie and what ... voltage) but i have set the final settings straight into the bios, so i didnt have to apply the setting every restart. but you have to choose witch method you find easy for your system, as far as i know you have to stick with one way of overclocking/undervolting if you would use different ways of overclocking undervolting it will make it unstable.. same if i would keep my bios settings + pbo tuner @ the same time it would be unstable aswell. hope you'll understand what i'll try to say.. there are different ways to accomplish the same result depends on how advanced you would like it.
@@RaphaelSwinkels ok yeah so I was wondering because I just changed this processor 2 weeks ago. Before it was a ryzen 5 3700 on a asus b450f gaming board when I updated bios the original processor all of a sudden was running really hot so I figured I would try to upgrade to a newer one. On air cooling but it went straight to 95c so I was doing a little research since I never oc or undervolted before and saw the core optimization under amd oc in bios and started at -30 which dropped my temp and improved performance and ran stable under cine23 occt and ryzen master but still gets to around 79-80 when gaming. Thought I could use both techniques thank you for the info
@@dragonsbane43 no problem.
Would it be 4.4 for a 7700x too? Also, should i be reseting PBO to auto before doing this?
my Ryzen master so different the interface you have how to change their no basic mood option also, I have Ryzen 5 2600x
What cooler is on the test setup?
Could doing this help with ddr speeds run more stable as well?
I want to go ahead and let everyone know, newer ASUS gaming MB’s default CPU settings in BIOS will absolutely fry an intel CPU. At least that was the case for my 14900kf. I built a new Gaming PC for my nephew and could not get core’s 4,5, and 7 to stay under 100C when testing on cinebench. Instead of undervolting, I had to go into ASUS Bios and turn down the default limitations ASUS had them set to. Instantly booted up and now running at the low 70’s on cinebench. No undervolting necessary and my performance score improved significantly. Feel free to message me for the info or if you want to make a video on that I would love to share this information.
I believe all the motherboard manufacturer's have been doing this on the intel cpu's and not just Asus. What is happening is that companies are trying to push the cpu as far as it can go to get an edge over each other as the default setting rather than using Intel's recommended limitations(which should've been the default setting.) It was a topic Jayztwocents covered.
I’m having issues with my i9-14900k and I’m newish to pc gaming I need some help. I have discord and willing to get all help needed without getting scammed haha put all my money I saved up for 2 years to build this
My man looking like Zues in that thumbnail ⚡
On my Ryzen 3900 (non X) using the method above, (setting to 4.3 all cores) i can't get it to pass using stock, i've increased vto 1.45 and it still can't pass. latest bios as of today 30/05/24 - is this because i can't adjust PPT,TGC and EDC in the manual setting ? (i noticed the auto overclock allows adjustments here)
#CyberCPUTech... you dont need to manuel undervolt, all you need to do is set CPU back to base clock speeds for a week in the bios. then after a week put all back. you will find temps will get lower as factories overclock the F out of it and dont reset it back to base clock before packing and shipping off for sales. I did this to a i913900k and it went 6 cores to 100% underload so i did that base clock reset.
Can we just apply the final ryzen master undervolt result to BIOS so we don't need to run it every boot?
Is there a similar application (AMD Ryan Master) for Intel processors?
i think its called intel extreme tuning or something similar.
@@Mrhorribubble true
On mt Rysen 5800X i went @ 1.2 @4.5 ghz,It will not let me go to the advertised speed of 4.7 ghz ,it crashes and reboots ,not sure what wrong
How do I undervolt the 7800x3d? These options aren't available for me. I've tried.
my 14700k can take up to 375watt in cinebench r23 so i do see benefit from undervolting but never thaught that amd could to with his low watt usages
But can you cinebench for 8 hours strait maintaining that wattage/clocks? I doubt.
@@DyceFreak Well with a proper case and ventilation yeah it reach 92degre celcius max temp and cpu at 5.8 ghz p core and 4.5 on E cores
@@DyceFreak i score amost 40 thousand points on cinebench r23 witch is the i9 score
That's a lot of juice.
@@DyceFreak i believe so.. that you could,i have my 5800x3d undervolted -20 + 200hz baseclock overclocked instead of downclocked. ;p it runs 24/7 @ 4375/4400 mhz allcore with the -20 offset voltage. offcourse every chip is different, but i feel like i won silicon lottery. maybe its not but i am happy with the differance on the cpu temps. it went down in temperture while i have set a continue boost frequentie on all core ;p. that's good enough for me ;p
Hay ZZ top, what about underclocking Intel 13th & 14th Gen ? Have you heard of Intel any wayz ?
Can you do a video on an Intel undervolt?
I don't have an Intel system that I could do it on. Sorry about that. Maybe if I build one for a customer I could do something like that.
Can the undervolt be done for the 5600x without running into issues by keeping the factory settings? With everything on auto.
The reason i'm asking is because there's no point in OC'ing the 5600x as the benefits from OC'ing this particular CPU are little to zilch.
Technically it's not an OC. In the video I simply set the bass clock at the maximum boost clock that the CPU is already rated for.
@@CyberCPU i understand but still is it possible or not? Because if it is i'd like to give it a shot.
Thank you.
Does this work for a 5800x3D? I’ve tried to under volt in bios via curve optimizer and it seems to increase my temps so I’ve stay with stock curve for my cpu.
yep it would work.
Not via Ryzen master, need to use bios or PBO2, as x3D chips are locked out from manual controls via RM, I have a 5800x3D
I have a ryzen 7 5800x, apply & test works fine on default ofc, but when I change to manual mode and not even change anything else, pc shuts off instantly when I run the test. Any solutions?
Hey buddy i have a Ryzen 5 5600G 3901MHz, 16GB Ram, NVIDIA RTX 3050...Do you think it's worth me doing this?
Doesn't hurt to try. I know the G cores differ from the regular Ryzens but as long as you do it based on your specific CPUs specs, I don't see why it wouldn't work well.
What's the advantage of running full time in an overclock that is still within the boosted range? Wouldn't the processor do that for itself if it needed to?
he underclocked his cpu in frequentie to get lower in voltage it helps in stabilty.. hope you understand what i try to say.. amd fluctuates in frequentie by default but if you say you have to run @ that frequentie, in that voltage range (that=nr you set it) then the processor straigh away is at the max speed what decrease latency between click/stroke by user
@@RaphaelSwinkels It just seems to me that if the CPU can run at 3.5 and boost to 4.4, that 4.2 would be slower than what the CPU could do on its own. The power savings is huge, I like that. The benchmarks (which I saw after my question) seem to prove he's right, but that seems to say that running at 4.2 full time is faster than running with boost going up to 4.4Ghz.
@@Taliesen. yeah indeed by lowering voltage @ the same speeds or a little bit lower, the cpu will maintain the advertized (or manually set values) for longer period of time... if it can't; the temp rises and it downclocks itself..
@@RaphaelSwinkels Ah, OK. the old "slow and steady wins the race". Thanks.
I undervolt my 5800x3d and wow it really run way better even tho my temp was 61c max know it's 56c max and I'm in Puerto Rico. I did it on my bios asus rog strix b550-f gaming.
I didn't even think that was possible on an x3D being they are locked down. From what I understand you want to be really careful playing with the voltage on an x3D.
@CyberCPU I bench all last night and if it die I'll just put my 5600x back all my cors hit 4449 and 4549 max from 3559 and 2879 . 61c max.
I've heard a ton of people say they undervolt. .2 - .3 seem to be the most common. I have no real temp issues, so I haven't bothered, so I can't back up these claims.
I undervolted my 5800x3d , passes 30 mins cinebench stress test. Never goes above 70C and only sometimes goes above 1.2v. All I did was go into the pbo curve optimizer in the bios ,set to all core/negative/20. From what I understand, you can go to 30, but I don't like pushing things and am quite fine with the results. One of the biggest issues with a lot of x570 boards is they are over volted out of the box and run a bit higher than spec even at default so they can win the benchmarking dick waving contests...
@@CyberCPU yeah, i've heard that too.. (5800x3d owner) i undervolted -20 offset + 200mhz base clock overclock, but all i won in temperuture reduction, i upped the baseclock slightly because x3d chips can't run too hot.. it never gets above 70 c now rather 60/65c while graphics card gets 79/80c @ 100% usage (only in some heavy demanding games).
but atleast the CPU is not getting hot anymore.. x3d chips are notoriously hot chips AMD said it doesnt matter it have to run hot.., but i don't believe them look how many 3600x's died prematurly because of to high voltage at stock.. this is how i learned the undervolting, because my brand new 3600x was unstable at the original high voltages..
i undervolted that chip and it did'nt crash anymore. while it crashed/was unstable on original voltages (for a year). ;p it still lives ;p i've put it in the new 5800x3d box ;p
thnks for your guides they are easy and relaxing to follow, i came to you as soon as windows 11 had a new
way to make older gen hardware more difficult to run windows 11// i even went out of my way to learn linux for my 7th gen skylake unsupported cpu ;p
my 5600 can only run at 4.65 GHz all cores (no clock stretching in Cinebench) with an undervolt, at stock with an increased power limit it hits the temperature limit for me. Ryzens have good temperature scaling, it can easily make a 200 MHz difference. But 4.65 that needs a good silicon lottery, not every 5600 can do that.
I believe I was able to hit 4.5. However, that took a little voltage to hit. It definitely wouldn't hit that undervolted.
Did someone get a new monitor? or am I seeing things?
No, I've had that one for quite some time. I did a review on it back when I got it. It's been a while.
@@CyberCPU Hmmm, maybe it is the new wallpaper... I used to not like Mondays but now they are my favorite day of the week!
❤😊
Undervolt or Overclock ? What's better!? ))
sadly got a 5800x3D and I wouldn't undervolt mine, its a risk doing that
I might get a 5500 or 5600x in my secondary pc to replace my 2200g
but I don't think those really need that either, but could make a interesting learning experience
either way
sadly you got 5800x3d? hahaha really?, yeah thats right its a good learning experience ;p, 5800x3d would run longer life on less voltage ;p
@@RaphaelSwinkels I'd replace before it even would die lol, but this cpu doesn't run that high of voltage, the highest I see it go is 1.29
which isn't that bad. But you need a 500 series board for undervolting on this cpu
and I'm running a b450 in both systems.
@@ChikaHakozaki aha yeah i understand they lock the overvlocking things out of other motherboard for money reasons.
@@RaphaelSwinkels yep, at the time of this upgrade which I believe was 2020, I got a ryzen 3600 and I saw no reason to get a x570 for a mid cpu, so I settled with a b450. b550 didn't exist yet at the time.
I upgraded to a 5800x3D last year, it dropped down to $300 and I thought that was a solid price. Sometimes I do wish I got a x570, but idk I just didn't couldn't justify purchasing that with a mid cpu at the time.
What about intel cpu's?
I don't have one to try it on. However, I'm sure you would have similar results.
I have an Intel CPU with -0.2200v offset from the default voltage using ThrottleStop and it's definitely worth it! I was able to drop the temp by 15c+ and the power consumption by a lot with the default clock/boost clock. You will have to stress test manually though as ThrottleStop does not have any built in stress testing. I do the stress testing by just playing resource intensive games, If the game crashes or any other abnormal thing occurs like BSOD or general PC crashing you will know that you have decreased the voltage too much.
What about laptop CPU ... It's logically more interesting and useful.
is it safe to undervolt our cpu?
You can actually damage your electronics by giving them too little power, just as you can using too much power.
I would like you to do a video on the ASUS 10bit TAG Support in a AMD X570 mother board. I turned it ON and my Render Speed went up 3x faster. And have no idea why this makes so much difference.
Damn the stock cooler for the R5 5600 is the most useless thing ever 😂 it hit cpu temp limit almost instantly 😂
how much perfromance do you lose?
edit: nvm you adressed it later on in the video
Silicon(e) Quality? ( . )( . ) 👀 😂
