Hey Everyone I am glad this video has been helpful to everyone - I haven't found the time to post anything more yet this year even though I had every intention of doing so. I appreciate all the subs and I will post another video once I find the time!
Thank you for the excellent video! I have one question, though:
CPU performance also includes your RAM, correct? Your performance seems very good. What RAM did you use?
@@Rico_______ nothing crazy actually just some midrange 3600 TridentZ Neo OC'd to 3800Mhz with the timings tightened & Fclk @ 1900 to keep 1:1 mode - here is a screenshot of my settings:

Wow those are high r23 scores for a 5800x mine only gets to 15749 how my ppt is 126, TDC 85 EDC 155 how come my EDC runs so high I set it to that but only Becuase if where the performance lies. Am I missing something I did this when I was new to overclocking so maybe I’m missing something
@@bosmang1 im running a 5800x and it doesnt like when i play with it very much in PBO and curve opt. it seems to run best on optimized defaults, PBO disabled and XMP 1 at just the two simple entries of 4.5ghz @ 1.15v. If I run stock voltage it'll smack 100c like it owes it money, even with a very robust custom loop setup...I get a CBR23 multi of about 15800 with just the two settings i previously mentioned. I am getting ready to try your methods. I hope this video saved my ass because I was about to throw it out the window. Thank you!
Really found it useful
I was messing around with pbo in ryzen master before but i wasn't really sure what i was doing...
i've noticed that after i set the curves to -24 to -30 (depending on core), I also set the cpu voltage setting offset to -0.5 v and that helps a lot with performance...
Also most stress tests, benchmarking software, games, get absolutely no errors even when i set all cores to -30, but there is one single game that for some reason reacts badly and starts crashing: red dead redemption 2.... really everything else works great, even running stress tests for hours on end, i wonder if it accesses the cpu in some unusual way if that is even possible? it typically only has about 15-25% cpu use in game according to rivatuner. Really that single application is the only reason i don't just set all cores to -30 and +125 MHz extra on pbo, instead doing -24 on the two most problematic cores and then -27 to -30 on the rest and "only" +100 MHz (this is on a 5600x so it's still pretty satisfying increase) also I set the per core voltage in ryzen master to just 0.79375.... this works very well with the curves set this low...
I find that setting the EDC to 119-124 is about the best for 5600x too for heavy multicore stuff and benchmarks like cinebench20, but i think for real world things, for gaming and such where you are not maxing out the cpu, maybe it's better to set it to something like 115 to keep the most busy cores going at maximum clockspeeds which i suspect is better for gaming performance, really for those situations i think you would hope the EDC and TDC limits are not even met at all...
The only guy that actually made this process truly beginner friendly
for real , i been looking around for days bruh
Best guide I have seen so far... better than big youtube channels guides.
Yes this is gold. THANK YOU!
@GameCrunch tbh any scumbag that wants to hack someone deserves to get scammed
For a 5600x what curve magnitude is best?
@@chrischeung98 all 5600x are different, you must do trial and error
By far the BEST! I might actually try to optimize my 5900x now to get lower temps cause of this guide!! Kudos to you sir!
Holy Crap! What a great presentation of AMD 5000 overclocking! Clear, concise, and high information content. Great job!
There isn’t a better video out for learning curve optimizer and PBo2. Thank you for making this video. I have had a 5800x for nearly 3 weeks now and tried multiple times at learning curve optimizer. Finally nailed it last night with your help. Thank you!
Awesome this is exactly why I made this video
@UMI i dont recommend it, curve optimizer is based on the specific chip, not the chip SKU
@UMI yes
@UMI He says is, so it's yes haha
@@bosmang1 when i try to up my curves over -15. on the good core i keep 10. i crash in ceni23 if i put the other cores more then -15.The thing is im confused because when i do the event viewer it shows its a problem with my main core but i dint change it i just changed the others?For reference i have a 5900x
It's incredible how much important information and how many tips are in this video compared to any forum or written guide i read before. And that's 7 months later. Very well done and big THANK YOU! Subbed.
Great Guide, was looking for this for a long time. Very well explained! Thank you
The best explanation I've come across by far, and I've spent HOURS looking! Far better than any of the so called big YoyTubers. Thank you so much!
This is probably one of the easiest videos to watch that I've ever seen on RUclips. Absolutely perfectly laid out, and any questions that popped into my head were answered a few seconds in the video. Much better than any of the "top" tech RUclipsrs..
I just got my 5800x today and only heard about curve optimizer a few hours ago. So I just went into the BIOS and set all cores to -30, did a few runs of Cinebench but nothing too stressful, and I arrived here because I was looking for a way to lower the curve optimizer further!
Suppose I'd better do some more stress tests and then mess with some other settings..
Found this video by accident and I was really positively surprised by the level of knowldege and effort you put into this video. Thanks for the work man and good luck with your channel.
Greetings from Germany.
Man this is one of the best tech videos I have ever watched, thanks a lot!
You've provided the best explanation across the web, and I can't thank you enough. I've been trying to understand the logic behind the PBO curve optimizer and this guide is quite helpful.
Excellent video. There are no short solutions, only patient advance through small adjustments. Great tip about finding which APIC ID crashed.
Thanks a lot, you did a great job covering the points. One of the issues I had was crashing and trying to identify which core it was. I had no idea I could find the apic id from cpu-z, which I don't think was covered in any of the guides I had watched.
Really great guide because it's perfectly balanced between simple and advanced concepts. Great job!
This is the best PB02 guide on the internet hands down, thank you very much really helped me understand PBO2 and get the very best out of my 5800x, Subscribed!
Dude, this guide is the best I've seen anywhere. Nice work
By FAR the best overview of how to do the curve optimizer in PBO 2.
This is the Single best Video guide out there for PBO2 Nice job man!
Really want to thank you for this. After watching so many others, I think you've got the best method to approach this curve optimiser and undervolting.
A solid two years later and this guide alone helped a lot to refresh my memory on curve optimizer and other tips helped such as TDC and EDC to be more aware about when undervolting.
Much love ❤
This is by far the best guide for achieving this ! Thanks
Wow, I always thought PBO was cool but after watching your video and playing around with the per core curve optimizer, I got a solid 12% performance bump over stock settings. All while getting lower idle temps. This was a game changer.
Also, the BIOS update that I needed for this had AGESA 1.2.0.0 and I was able to run my Infinity Clock at 2000MHz at 1:1:1 with some DDR4-4000 RAM. System has never run so well!
Just wanted to thank you for making this guide. This is the most thorough and easy to understand video on PBO that I've seen and it was extremely helpful.
I don't comment often on videos but felt I had to after watching this one.
This is the best PBO guide I've seen because you bother to take the time to explain each setting and what to consider when adjusting it.
Great job dude, subscribing for more content like this!
I don’t like videos, god forbid comment. I watched your video and closed the app. Then I thought about your video and all the incredible data you had spent days pouring effort into to share with us. And then I reopened YT dug this video of my watch history and came back to like and comment, and even subscribed. The quality of this video and explanation of its data; is, simply put, incredible.
Thank you very much, this was great information and presented well. You actually show and explain what these acronyms are and why we are changing them, which ones may be better for you under what circumstances, and how to do the gritty parts such as determining which cores crashed. Much better than most of the other folks with un-useful videos/posts just telling their story of shooting for the moon and how you should crank your settings up very high. I am interested in hearing more from you :-)
My man, this was the most well explained PBO2 video I have found on RUclips. Thank you!
I've looked for information about pbo2 by reading/watching guides, none of wich were as detailed as yours, hats off sir :)
Best guide on PBO so far. Explained it perfectly 👍
Finally a complete PBO guide with precise technical information as I like, and with many graphics to really understand the subject. Thank you very much for dedicating so much time and effort to help others. I subscribe to your channel.
I finally understood PBO and especially the "curve optimizer vs. boost".
Thank you for this video - it really is the best on this topic.
You explain things clearly. Not as common as you might think. Great guide, and I hope you make more. Subbed.
Thanks! That was REALLY helpful! The AHA moment was that you actually have to undervolt more the worst cores and not the best ones :)
I think you are the only one who made the important comparison between Boost and Curve. I've been looking for benchmarks on this for ages. Thank you
Great video!
I too like many searched and searched for somebody to break this down for me.
I feel like I know enough to play around a little now.
Thank you!
Excellent video. This is the best guide on this topic I've read and seen by far.
Wow, this guide was really good. Thanks for that! Subscribed.
Thank You! Best tutorial on youtube explaining how to properly use PBO and Curve Optimizer. I've been mopping around scratching my ass for the last few months trying to figure this stuff out, until you laid it out there easy peasy! Cheers!!!
What an awesome guide showing solid evidence backing up all of your claims! Thanks a bunch, I feel like I have a MUCH better understanding of how to tune this now!
I was getting black screen reboots when I had turned PBO on on my 5950x and now thanks to your video I understand that things are more complicated then they initially seem. Very detailed and well explained,thank you.
What was your solution to the black screen reboots?
This is an excellent guide for setting up Curve Optimizer and the exact process (even down to the Event Viewer APIC part which is the most crucial part for end users) I followed on my 5950X.
Which settings have you changed in your 5950x and which values you added my friend?
Exactly what I was looking for! Switching over from Intel to AMD next week! And apparently there's a whole lot to learn Thanks man, subbed!
Seriously good video - very concise and easy to follow breakdown of PBO, Curve Optimiser and how to approach using them.
Super useful, best guide I've seen yet about this. Curve optimizer really seems to be the crowning achievement of the 5000s! Would you be willing to give out your spreadsheet template that you are using to chart out those graphs so we can track our scores as we go?
Great guide. One tip to add:
CPU Load Line Calibration in your BIOS can do a lot to stabilize more aggressive Curve Optimizer offsets. e.g. The two best cores on my 5900x are capable of much better offsets if I change LLC from "auto" to "level 3" on my Asus motherboard.
Just don't set the LLC too high -- voltage overshooting can degrade your CPU. You can google recommended LLC levels for the various motherboard brands. Generally a medium setting is best.
thanks, i manage to get the best settings with my new 7900x also pbo per cores with llc lvl 3 really goes well together
Thank you for this video. I've just switched to a 5800x (first AMD chip) and had no idea how to overclock it effectively. All I saw everywhere was enable PBO and use the curve. You actually explained what these options do and, more importantly, HOW they work. Great vid.
Hey, I really appreciate your guide. It is my first time with AMD and I was so lost in the BIOS. Keep up the good work!
what a great video for ryzen5000 pbo 2. helps me a lot! big thx and blessing from China.
THANK YOU! My goal for my 5800x was to get over 16k multi / 16xx single on Cinebench R23 and your discussion really helped me tune to those levels. Really insightful presentation. Thanks again!
What mobo and edc+tdc?
@@nnnnnnsssssss yeah I wanna know that lol
Very cool and in depth guide. Shows how amazing the ryzen 5000 cpus are. Even with super precise overclocks, you barely get much more out of them. Amd have really put the work in to give us the best already. Very very impressive.
Wow, thanks a lot! This is by far the best explanation about this subject on RUclips. Big thanks for the tip how to find out what core is crashing!
Extremely informative. Just got a 5800x and want to see the capabilities of PBO 2. There's lot's of information and input from other people out there about this, but your information gave me the confidence to go ahead and test with PBO. Thanks!
Great video! Just wanted to add that you can use a program called y-cruncher to determine which core is unstable. It has a Component Stress Tester (option 1 when you run it as is) that runs a series of tests until an error is encountered, in which case it usually tells you which logical core caused the error. Just take note that the tests will really work your CPU to its thermal limits (90 degC for my 5800x).
Holy crap you're right. I cooked 6 eggs on my tower roof. Y cruncher is neat
By far the best one I have seen over the days! I have followed this guide to tune my 5900x.
Thank you for this! I didn't know that negative curve should be lower on higher-rated cores. I have been struggling for a year. I Subbed because you took your time to explain everything and every detail.
Best guide out there. Subscribed.
Lots of stability testing, 5900x says nah, I maxed that bad boy to -30 on the optimiser and picked up 3000 point in an all core cinebench test 🤣. Thanks for the video it's really really good at going in depth to what all the abbriviations mean and how each value effects the clock and power limits
I am absolutely new to AMD Ryzen overclocking. I have been looking on forums and videos on youtube. This is by far (probably) one of the BEST and simple explanations of how this works.
Great job!
I've scoured the internet for the past 2 weeks for guides and information on PBO2 on these chips, and this is by far the best resource. Thank you!!
Great stuff! Swapped my 1600af for a 5600x and was overwhelmed at all the options. Loving it though, PBO 2 seems really awesome, efficient and stable but it barely did anything out of the box until I began messing with the curve optimizer and following your guide. You got a cool channel here, have a new subscriber.
Also you look a lot like Kurt Cobain lol
I also have a 5600x, how did you set yours ? I'm aiming for low voltages for better cooling while trying to not lose any performance
I knew all of this BUT you explained it better than anyone else I've seen, so keep up the good content sir!
You have NO IDEA how many hours I spent fiddling with the bios settings before I stumbled on this video.
You just gained a new subscriber!
Well done guide! In fact by far the most complex 1 on RUclips. Cheers
Really good guide, thanks! I've found that I could be stable on all the intensive CPU tests but I'll get crashes (blackscreen / reboot) when idling, no WHEAs logged. For now I've just abandoned thte PBO altogether (stability being more important than outright speed) but I'll come back to your guide when I have time to play with it :)
Idle crashes are 99% of the time from the best cores marked by ryzen master. Try setting those to 0 and do the other cores first then come back to them
@@bosmang1 Cheers, I'll give it a go. I started off that way, but I found that just a small negative offset on those cores seemed to have a big effect on core speed (and benches) for all-core loads. Of course, that's not much use if it crashes at idle. I'll need to take your advice and be a bit more systematic in my testing this time around as well.
@@bosmang1 eh Bosmang, we no wanna give advice to a wellwalla. If hes a real beltalowda , den you sort him out right, tell him all de tings he need to know about de curve optimiza, for de belt!
Excellent tutorial. The only part missing was the CPU temps you got during those runs. I'm interested in the temps because this Ryzen7 5800x CPU, in particular, runs hot. I had to reduce the PPT to 109 to get the temps in line. Cinebench r23 runs 14,800 at 78C whereas before it was doing 14,800 at 86C.
If there is any way to get close to your Cinebench score without going over 80C then this is truly amazing for me.
The temperatures are in there, look at the graphs he calls "delta temperatures vs EDC" and "delta temperatures vs TDC". Those are degrees over ambient. It doesn't matter if your CPU hits 80 degrees C and his hits 85 if you're in a 15 degree room and he's in a 30 degree room, those are totally different baselines. Delta-T eliminates this.
Thanks so much, 2 years old but this is still the best, most intuitive guide on the subject on YT!
Absolutely AMAZING guide, man! I just got a 5800X I can't wait to do this! You deserve many Subs, my friend.
Best video i've seen so far, sa sa ke?
Any chances you can do a similar video of how to OC that sweet RAM we all probably got for our 5k Ryzen? I am sure a lot of people need one well-explainted video to be out there!
Would be great to see such a comprehensive guide!
You killed this man! Had a couple shots at trying all core and couldn’t get the thing stable at anything worth while. This guide made it possible to squeeze as much as could out of my 5900x
The best video I have may ever watched regarding a tech video. Very helpful!
Hey man, great video, very clear and helpful. One thing I have to point out is that I can achieve better results controlling the temperature by limiting the PPT instead of the EDC. By that I mean leaving the EDC very high and turning down the PPT limit. I can have my 5600X achieving better results (at least on CB23) with lower PPT limit than with lower EDC limits, maintaining the same temperatures between this two different approaches. Might be different from chip to chip but thought you'd might find it interesting.
This is similar to what I present in the video. The idea is you find your best performance with EDC and then use TDC to lower temperatures. This will overall give you higher performance per delta T than just lowering EDC. You on the other hand used PPT which in turn is most likely lowering TDC but I can't say for certain because I use TDC to tune for temps and leave PPT to be whatever it ends up being based on the EDC and TDC.
I just did -20 CO on all cores and limited my 5800x to 120 ppt 115 edc and 75 tdc. I have roughly stock performance but at way lower temperature. It went down from 86 to 71 C. You are awesome mate. I don't have time to do per core CO and i don't need +50mhz OC. My cpu on all core load boosts to around 4,475-4,525 mhz at around 1,2V. At stock it was similar but with higher voltage.
I copied your settings and I’m liking what I’m seeing! My cooler is definitely what’s limiting me but with these settings I’m sitting around low 80s which is fine with me.
thanks a lot, i waited so long for such an comprehensive guide :)
Thank you for this fantastic breakdown. Got a 7950x3d and wanted to try and get the most out of it. This video really doves in and explains stuff so well that you actually understand what you’re doing, and I think that’s critical to the safety and efficacy of messing with these things.
Many thanks for this awesome guide. 5600x stable at -30 on each core with a +75 mHz boost offset. Raised PPT to 130 essentially uncapping power limit, slightly raised TDC to 65 and EDC to 95 from stock settings to pass 4.6 all core boost while reigning in temps a bit compared to mobo limits. Also keeps Cinebench multi past 11900. Hope this can help other 5600x owners just make sure you've got good cooling, she gets hot

As everyone's said, this is a fantastic guide and many thanks to you sir! I have a 5800x on the way and no overclocking experience, so this is absolutely invaluable.
I've subscribed and I'd love to see more PC tweak guides, such as RAM tweaking or more information on testing (need to look up how to test effective cores), if you were up for doing more. Thanks again!
This is the best undervolt video i have ever seen, you explain everything and not just give random values for the bios like the other channels.
Nice to see such clear and concise discussion without the hyperbole that so many seem to include in videos. Hope to see your following grow and recognition for your efforts :).
I noted a bit of discussion around crashes occurring at idle when fairly aggressive undervolting is in place. A suggestion was to increase the base CPU voltage slightly, and then maintain a high offset in the curve settings which seems to work.
THoughts?
RAM Overclocking will be the next effort. Got a guide coming on that? :D
Thank you beltalowda!
Amazing explanation, I tried curve optimizer on my 5950X early on but didn’t work it out. I thought the best cores would respond to more undervolt, it seems it is actually the opposite. Also I didn’t do the WHEA logger view in Event Viewer so it was all guess work as to which core crashed when there was instability which became frustrating very quickly. I’m going to have another go at it now that I’ve found this video. Subscribed!
Yes! Brilliant video and brilliant descriptions of what each setting does and how to find the best for your setup. I just updated my sim racing rig to a 5800X and an Asus ROG Strix B550-F and am currently in the process of tuning. This video has helped me the most out of all of them that are out there. Thanks for this.
How stats u have TDC and others?
You're a legend man you covered every single question that had entered my mind when I first looked at undervolting my 5800x.
Very good guide, would be good if you could add to the the google drive spreadsheet (of zen 3 PBO/CO) I posted it in reddit thread, also post your video in the overclocking subreddit as well.
Thanks for the very clear guide, the key part for me was adjusting the curve down to 5/10 for my best and 2nd best COREs on my 5950x. I still only get 28100 and 1465 with your ECP/PPT settings so not sure how you are getting 10% more performance! Any ideas? RAM over clocking maybe? Could you share your other BIOS settings?
I'm not 100% sure but from what I understand, no two cards are the same. Settings for his card will be different from yours due to the "silicone lottery". That is what I've read and understand about tuning a cpu.
Thanks! Been looking all over for a video that explains this and shows the bios settings.
Total noob here, and just wanted to say thank you! This was so incredibly helpful and explained in a detailed yet simple enough way where someone like me can understand and actually get a stable underclock with boosted mhz! Thank you!
I want to let you know that your video helped me over clock and diagnose my 5950x overclock super well. It's been a couple months but recently I've started crashing due to CPU and I tried looking for the WHEA errors in the event log, however, nothing WHEA related shows up, not a single one. This is super weird because I remember diagnosing which core was at fault on the curve using the event viewer for whea, but now it's blank whenever I try looking for any WHEA errors. Any ideas?
THANK YOU FINALLY STEP BY STEP WITH TIPS!!!!!

thank you dude, you are helping the community a lot, i'm here from brazil and thanks for all the tips. I will start my journey and find the perfect curve for my 5600x. Strong hug and success always!
What an amazing guide. Really going into depth on the how and why. Thanks to you i've managed to finally make my 5900x stable
May I ask for your opinion on effective clocks: in heavy workloads (like CB) the effective clock is similar to the set Frequency, but if you for example have a lighter workload (like gaming) the effective clock is way lower then your possible max boost Frequency.. what does that mean? And why ist that the case... (Is it "wrong" to look them up maybe?:)
Thanks for the nice guide! Although i dont understand for some reason boost override doesnt want to boost my single core performance :/ Ive got -20 and -25 on my best cores and -30 on my worst cores, although i tried to lower it to get a higher boost. The max i can get is 4950mhz (5900x).
Thanks for this excellent and detailed video guide. Really helpful. Keep up the good work!
This is great. I got most of it. The intimidating thing is the waya and finding core that crashes.. Never heard of it and you zoomed through that part so quick
Amazing results on my 5950x + x570 msi tomahawk. I’m running -10 on two best cores, -30 on all the rest. 500/210/220 ppt/tdc/edc, +50mhz and I’m getting CBR23 of 30394. Temps hitting around 85 degrees during benchmarking. I can’t thank you enough! The logic behind: get the curve working without whea before touching anything else is the real gem, along with the event viewer trick.
VRM temps hitting 43 degrees maximum. I’m running AGESA 1.2.0.0.
When you say 2 best cores... Do you mean the two cores with a star (one on each CCX) or the best two cores from CCX 0?
@@shaolin95 the two best on ccx 0 buddy. Since posting I went up to -5 on those two cores and a couple of cores to -25 when they were crashing with whea’s. I pushed the boost to +200mhz and scalar 10x. It gives much better single core performance now.
