    1usmus has changed the name of this software: It's now called CTR - ClockTuner for Ryzen! We have also received updated guidance on ASUS motherboard LLC settings - It should now be 3 to better catch errors.

    • Zlyxe

      well I started it PC crashed and after it booted again, i can not get it to start again CTR 1.0 and CTR 1.1 neither of them

      Let me be very clear. I respect tech journalism, and only wish we had more of it. If anyone is off put by my style, its calibrated to get attention, precisely because my nobody level of personal audience. I 100% recognize that is the easiest target since what im actually putting forward is only interesting to a certain kind of person that has curiosity. This stuff isn't rocket science. If anything id like to bring it more out in the open, since its very easily demonstrated by anyone thanks to my guide. If my autopsy comment is too abstract for you, that means im happy to take apart a dead nonexistent argument on arrival. To be fair as well, I haven't found a tech channel yet that covers some aspects of optimization across libraries of application where the thread scheduler can introduce penalties under certain CPU combination. That's sort of forum digging, and experimentation. Numbers they say dont lie. But I know from experience, they sometimes absolutely do. Im not even that advanced a user. Imagine if we can get the fastest path for ryzen, that isn't literally just running intels path. Because its more than just 1 or 2 games, though the real question is, is it findable in a modern software environment. Its kind of inevitable at this point. Im happy to speed the process. Im not invested in the same way. Imagine how this might find its way around the place with those leggies, and how preemptive patching could be in order before it gets too loud. That would be the wisest decision I think. Everyone with an AMD processor wins, and they might not even know it basically. Settle down though because im not Tech Jesus. Only Linus has that title. Wait.... Thank you for calling out nvidia on that little tid bit. I can only guess its not the actual titan though.

  • Mr Belter
    Mr Belter

    CTR told me i had a bronze CPU and my 3700x ended up running slower than stock sadly.

  • MrImTheOne100

    Seems like AMD is trying to give us CPUs/tools to tweak the CPUs to run them forever until they die out on us. S U P E R C O O L ! ! ! RIP Intel 😵

  • ShamelesCampR559

    I was so excited to try this till i heard you say i gotta download Ryzen Master, and im here because im on linux, annnnnd wine doesnt do Ryzen Master sadly enough. if you could do a video of how to do this on a Linux based OS im all for it

    • Marco

      Maybe install windows temporarily, run this software, write down the parameters so you can apply them manually in the bios and finally come back to linux ?

  • SuperCarl513

    I tried this and it crash my pc. it won't post anymore. If you encountered this same problem, try flashing your bios to the latest one. Hope it helps.

  • Jerry Roncalli

    i keep getting error running ctr that bios is out of date along with ryzen master. they're both up to date, no newer versions. bug in software? using ctr beta 7 version

      Ryzen master gets my temps down but my bios just does t work right... everything has been updated bios processors and everything

  • Asmodeus

    my r5 3600x gave me reference voltage 1250 mV and diagnostic Voltage 1225 mV is it safe to use?

    imagine if the comment section talked about results

  • Bordlampen

    where do i download this ???

  • CapHunterX

    I just did this on my ryzen 5 3600. Default with pbo enabled it run at 4000mhz 1.35v and now I got it running at 4275 on one ccx and the other 4250 at 1.25 holy cow Edit: temp are 10c down Edit: undervolt got me to 1.175volt at 4.175mhz

  • TechFan

    I'm a little concerned about setting LLC to 3 or medium without dropping the voltage in the bios immediately, or at least have some numbers using the multi meter to determine what the Voltage and amps are doing.

    From Linus's permission, I want to say that we with 1usmus made a guide for the Clock Tuner for Ryzen, explaining everything and going through all steps that will help to ensure that you get most of the performance from CTR. If you have any questions, you can ask it as well 🤓

  • Themidnighttrain7441

    Mines a Ryzen 5 3600X I don’t know if that’s been tested yet

  • Jason Nemeck
    Jason Nemeck

    Would be really nice if I could find what Anthony was talking about in the BIOS...far as I am concerned this is garbage. Software doesn't DO what they show. Errors in log. Cannot load or see log. CTR software demands over and over that I download Cinebench. Uninstalling this junk.

  • OneTruth

    did all the stuff. But in CTR my ryzen 5 3600 showing only CCX1 and CCX2 Running. The other cores are off ? Why is it like that ?

    Could I use this on my R3 3200 though? Or, maybe I could, but it would be a total waste of time for me? xD

  • stoneybridger

    If it BSODs does it remember where it got to? or do you start from scratch?....i can just picture running it for half an hour, walking out of the room and it crashes.

  • ZoMbIEx23x

    Anthony is cool. I want him to accept Coach Greg into his life so he can overclock himself.

    I love Anthony. He's so clear with his wording and I vibe everything he presents. 10/10, someone I'd like to share a beer with.

  • gregnome

    Tried CTR, found a stable setting, then applied it through BIOS. So far, so good. Got 5% performance boost, even though I massively undervolted my CPU (from 1.35V LLC1 to 1.265 LLC3).

    On my 3900x, I got a 10% boost in multicore and a 1-2% boost to single core. Power draw is down 20-30 watts, and my thermals dropped 5-7 degrees C. This program worked insane for me.

  • Edward Ireson
    Edward Ireson

    If CTR camt see your core quality and just displays 100 next to each one then clear your logs in event viewer.

  • MadLane

    how is this for ryzen 5 3600? worth trying? I'm going to buy one.

    Why is not something like this just bundled with the cpu?

    This are my results. Test made with this setup - Ryzen 5 3600x + RTX 2070 Super + Motherboard x570 Asus Crosshair viii + 32gb Ram + Custom Watercooling. I must say i have an amazing temps with this OC witout performance loosing in games... yes, my cinebench and clockspeed are lower but the tems test in and witout games are much lower. NO OC ⦁ clock - 3800 ⦁ Tem min - 42 ⦁ Temp Max - 73 ⦁ cinebench - 3343 ⦁ max fps control -92 ⦁ max temp game - 52 ⦁ Voltaje: 1.43 ASUS OC AI Suite 3 ⦁ clock - 4200 ⦁ Tem min - 44 ⦁ Temp Max - 79 ⦁ cinebench - 3373 ⦁ max fps control - 91 ⦁ max temp game - 53 ⦁ Voltaje: 1.35 OC CLOCKTUNER ⦁ clock - 4000 ⦁ Tem min - 42 ⦁ Temp Max - 66 ⦁ cinebench - 3162 ⦁ max fps control - 92 ⦁ max temp game - 48 ⦁ Voltaje: 1.25

  • Garbundy

    For anybody still on zen or zen+ I would highly recommend in still following the setup as I was able to push my ryzen 2600 non x to 4.1 at 1.375 volts whereas before the setup process I was lucky to get a stable clock at 4.05 at over 1.4 volts.

    I get it, but does it means that it change the setting in BIOS for you thorugh this software? uhm, we gotta have it up and running everytime we start computer? Else where back to start.. right?

    Jordan Walker

    Every time I run CB20, press Diagnostic or Start, it fails and tells me "there is a need to reduce LLC". I only set the first LLC option to 3, but there was an N/B option too - do I need to do anything with this as well? Is my OC RAM to blame? R5 3600 Patriot Viper 4400Mhz 16GB kit > 3600Mhz CL14. Would really appreciate some advice if anyone can figure out what's up. I know very little about this sort of thing, and what I do know is just from trial and error.

    • HymenopusC

      Known bug. Leave LLC at 3

    Downloaded and ran CTR (public release) today after work and first game I launched (COD Warzone) crashed. It's never crashed for me before. Not very impressed! I noticed my CPU wouldn't clock over 4200 mhz after the profile was set and applied. I have a 3900X. I did gain 100 points in Cinebench but what's the point if my CPU is crutched from high clocks?

  • TheStigma

    I really hope 1usmus adds support for zen3 to do pr-core tuning. That granularity should allow you to squeeze out even more performance. Does anyone know if that is in the works or planned? Feel free to drop me a reply :)

    So basically AMD has all those cores and threads and still isn't as stable as intel for gaming and overclocking. All that trouble and still can't run a stable 5.0ghz. Thanks for the video. I'll stick with intel after watching this.

      5ghz is a marketing meme.

    It is funny how nobody remembers the "aren't these voltages a tad bit high?" thing. Or the fact that the cpu's couldn't reach their advertized clock speeds. Now that somebody basically manages to fix these issues. You all talk about hidden performance.

  • vax1977

    I did this manually with my Ryzen 5 3600 a while back. Had it stable and happy at 4.4GHz all cores with verifiable performance increases in benchmarks, no BSODs in Prime95, using about 85%-90% of the max wattage and at around 1.3v for the CPU while under stress. I noticed a lack of other people doing this on the Internet and began to get nervous that I was doing something stupid so I validated it on CPU-Z's website and then put it back to stock. Just upgraded to a Ryzen 7 3700x so I after seeing this video I might do another overclock/undervolt again and leave it that way since it seems to be the general consensus that it's safe enough.

  • Shinobi

    It works with Ryzen 3 3200G?
