Slight correction - some users are seeing PBO2 available on B450 motherboards.
Another update: It is available on some boards with AGESA 1.1.0.0, including my Crosshair VIII Impact. Just tested the Ryzen 5900X in my own system - it can do a negative offset of 25.

MY Ryzen 7 5800x with a -30 offset: Novabench showed a jump from 4.68 to 4.83 GHZ and an overall score increase from 4195 to 4245. CPU runs 12c lower at idle and roughly 8 - 10c lower under load. Great information and a real worthwhile tweak for 5000 series users.

5600x user here. Wasn't able to apply -30 to my chip without introducing instability in games soI dialed it back to -25 and it's been rock solid now for nearly a month both in games, when idle and during stress tests . My temps dropped by 10c and my multi core cinebench scores went up by roughly 200 points! Incredible

[asadianbelifont]

With a negative offset of 30 this literally reduced core temps by 15 degrees while maintaining a higher clock speed, no joke. Any spike in load would cause my 5900x to jet up to 70-80 degrees on a 360mm aio, after applying this, that temp is around 55. Insane!

Ali... it's 6am and I shouldn't be doing a BIOS update and tuning an undervolt... but here I am doing a BIOS update and tuning an undervolt.

Finally a guide by someone that really know whats he is doing.

[JFinns]

Thanks for the bios walkthrough of PBO2. My 2 year old 5800X saved 20 watts of package power with much lower thermals, while still scoring 3% higher on Cinebench at 15, 750. Wish I did this sooner.

This video still adding value. Just turned PBO2 on negative curve like the video suggests, managed to attain -30 first time. Can see all cores under 100% load hitting 4.3Ghz sustained with a vcore of 1.1875. Max temps were 66C on a 240 aio on a SFF case. Really cool, entire thing is a lot quieter now. Thank you!

easily the best ryzen undervolting guide I've seen, amazing content as always!

[e_Moses]

You went over the most important part of all of this in the video which is stability testing. The main issue that I found while trying out the curve optimiser is that even though you can test it each core individually or all cores at the same time with different stress testing programs this will can only guarantee stability during intensive workloads. Most of my crashes that I faced were while the PC was idling. I haven't found a consistent way of testing this aspect of the curve optimiser. I have checked reddit posts and different forums and I've seen people complaining about the same issue. The PC can be stable while running prime95 all night but it will crash while you just browse the web. I propose you do a followup video after you use the system for at least one week with the settings you showed and then report if the system was actually stable. Maybe even make a video that covers stability testing.

Amazing, can't believe I've slept on this extra performance for a year 🤣 got my 5900x paired with a msi b450m gaming plus motherboard running pbo 2 with curve optimizer at negative 25 with auto oc set to +200, Getting identical temps as before with 3-400 mhz improvement in clock speeds in single threaded workloads and in cinebench r23 multi core test it holds a solid 4.6ghz all cores. Thanks for this video! Highly appreciated!

[bobbymoss]

Thank you for this brilliant straight forward guide. I just got the 5600X and hope to run it cool, rather than max out the OC, this guide's perfect for my needs.

[thedofflin]

Yeah this is brilliant and seems like something a lot of proud overclockers would completely miss. After undervolting my 5600x by the max amount, and undervolting RTX 3080 to 0.85V @ 1875MHz I use a maximum of like 300-350W when playing games, not a single hitch. Crazy stuff. Combine that with Noctua cooler and case fans and my PC is almost dead quiet at full load, and generates a lot less heat.

Undervolting all the way. So much more satisfying to have a highly efficient PC, rather than raging inferno just for a few more fps.

I appreciate that your video isnt full of filler stammering, um's, uh's, redundantly repeating yourself here and there, very straight forward, to the point. Im so glad i found your channel, you got a subscribe from me.

[dingleberrydan]

5600X with a -30 offset, Arctic 240 aio, and 4400mhz Ballistix is scoring a 4610 in CB20. Maintaining a 4.6Ghz core clock while not going above 55c. 3 years later this thing is still holding strong at an insanenly low price.

[belema]

Absolute champ, I've watched almost every video and learnt so much from you! You walked me through my NZXT H1 build, undervolting my 5700XT, justified my already purchased EVGA 3060ti XC and now this. 🙂

[harishannamalai]

The thumbnail of this video was more dope than what AMD themselves could do.

The content was great too!

[bradyb]

Bro I literally just copy and pasted this into my bios, and it literally worked first try. I have a 5800x. Went from 4, 499 MHz to 4600 MHz and it went from 87c max to 85c. This is insanely easy and insanely effective. I’m for sure subbing for this video. So easy to follow

[jabuki]

great video. This gives a noticeable increase in 5600x CPU frequency. Which in turn gives much better gaming minimum framerates and framerate consistency. This is probably the most important factor for gaming and not max framerate.

[antonpoddubnov]

Was able to set negative 30 on my 5800X and got a big performance boost out of nowhere.
I can’t thank you enough for such a useful info!
