The result with an air cooler and PBO and AutoOC enabled was very slightly worse than the other three, presumably because of minor temperature fluctuations from repeated loads in rapid succession, or from a reasonable +/-1C change in room temperature as AC fluctuated, but it’s still a difference of barely more than 1FPS from the top result (which was achieved with PBO and AutoOC disabled). AMD’s first- and second-gen Ryzen™ desktop processors have been a massive hit with both gamers and professional users everywhere. I also use my PBO setting as Auto. There’s a 2.6% improvement between the worst result and the best result. While enabling PBO and auto-overclock is useless on the 3000 series due to FIT, the 2000 series will not be limited in that capacity. " Last modified on July 15, 2019 at 10:45 pm, “More clock speed, for longer, means more performance. ", If AMD were so confident in the pronouncements you describe then could you also explain to me why the very use of PBO voids the AMD warranty for their CPUs? The very first thing to do is in Ryzen Master go to "Profile 2" (I will explain why Profile 2 further down) and set the Control Mode to "Manual". Patrick, who wrote most of this script, noted that he hopes everyone can appreciate the amount of time and effort we’ve put into testing a feature that nobody understands and that barely does anything. Do PBO and AutoOC give you a performance boost? You can follow Buildzoid’s guide on YouTube but he rambles a lot so here is TLDR: Find PBO settings in your bios and set it all to manual values: PPT Limit: 300; TDC Limit: 230 To be clear, the score I posted above (529, 7451) was run with precision boost only, not PBO. Anyone else have trouble getting Ryzen 9 3900x to boost at 4.5 or 4.6 single core on Crosshair VIII Hero Wifi board? "This was my reason for limiting the performance of my friend's CPU to be in line with the spec of the 7nm node as expressed by TSMC and this allows me - and of course others - to configure the CPU optimally whilst remaining within that spec, whereas any and all methodologies supplied by AMD in the form of PBO and Auto Overclocking voids the warranty of their CPUs.". My Setup. Manually on "Profile 2" at an all-core of 4.25 it got 7028 and on "Profile 1" it got an all core score of 5143 at 4.35 GHz. We didn’t run all tests on all configurations because it would have been a waste of time; the tests in the charts are the tests we ran. What is the single threaded Cinebench R20 score of "profile 1" configured as you described? The worst result for the 3900X in F1 2018 was with the air cooler and PBO/AutoOC enabled; the best result was with a CLC and PBO turned off. Today, we’re demystifying these names and demonstrating the basic behaviors of each solution as tested on two motherboards. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. On the X570 Master with the R5 3600 and PBO disabled, Cinebench R20 scored 3759 multithreaded/484 single threaded. That’s what we did for our review, just like how we disable MCE for Intel. Remember when I said that you were to configure "Profile 2" and I would explain why? Today someone approached me on Discord who was confused about configuring his 3900X system and asked me to help. So which setting is it Auto or Enable, and if its not Auto then why, what does Auto do? It's normal. If AMD were so confident in the pronouncements you describe then could you also explain to me why the very use of PBO voids the AMD warranty for their CPUs? Our CPU review results are from an ideal scenario, showing the baseline maximum performance, and users who aren’t using a 280mm CLC on an open-air bench may not be able to match our performance. Cinebench R20 Multi-Core Scaling . I would appreciate it if you could give information about how PBO and Scalar settings should be. 3900X with NH-D15 running at 90C at stock PBO settings... Help (CPU) Hoping someone can offer some advice or insight on this:I've got a 3900X, on a Asus X570-E Strix board. Which cooler were you using for the testing? pbo on, default settings, small fft w/avx2, read settled svi2 core voltage, that's the actual safe voltage you can run your specific chip. For once the results somehow lined-up in a sane and reasonable fashion, with the two PBO/AutoOC enabled tests at the top and the two stock tests at the bottom, with the best result from a CLC and the worst result from an air cooler. As I said, in the 3000 series enabling PBO and auto-overclock doesn't do much as the CPU is already FIT bound. For gaming performance clockspeed is important. $464 USD . Congratulations, you have found the sweet-spot for your CPU and what is more, that clockspeed will give you a higher single core score than setting Ryzen master even to "Auto Overclock". However, here the stock setting offers the best performance, followed by PBO and AutoOC seems to run into a hard power or temperature bottleneck. My CPB setting is in auto. Also note that there are separate default PB limits for 105W and 65W TDP processors. Even at Wraith-Spire-that-isn’t-rated-for-the-3900X temperatures, PBO didn’t make a significant difference. At best it will allow the CPU to maintain boost clocks longer and more often, and therefore PBO will have the strongest effect on scenarios where the CPU is already able to boost. Just entering “200” does not mean it’ll always offset by 200MHz, it’ll just offset by any point within operating limits to a maximum of 200, similar to GPU clock offsets. We’re never seeing the 200MHz boost from AutoOC. With the 3600 on the GB board, there’s also less than a 1% increase between the two scores. 0 1 minute read. Precision Boost Overdrive. You'll notice that the preset PBO settings (PBO Enabled) result in lower voltage and clocks frequencies with the Taichi. Thermals. So now that you have configured "Profile 2" you take those values and apply them to "Profile 1" and then the only thing that you change is under "Additional Control" you set "Simultaneous Multithreading" to "Off". Next go to "Memory Control" click on "Included" and make sure that he slider is set to half of the rated value of you RAM (that is, if you have 3200 RAM you set the slider to 1600). For these runs, we scored 514/7078 1t/nt with PBO off and 520/7235 with PBO and AutoOC on. The default setting for PBO is “auto,” which the stock specification defines as disabled; further, AMD’s own review guide states to disable PBO for reviews, as the Overdrive portion is not spec. When you have set the value then go into Cinebench R20 and under "File" then "Preferences" set the "Minimum Test Duration" to 300 seconds. If I enable PBO, my EDC only makes it to 63% of the new limit, (CB20 score ~7500). Or: Replace the Wraith Prism with a quieter … I still boost to 4.6 GHz, because I'm at 1.48V, which FIT will not allow my processor to pass. Do you have the white paper from TSMC? AMD Ryzen 9 3900x Computer Processor, comes with the original box, but without the wraith prism cooler. AutoOC is slightly slower while Precision Boost Overdrive just messes everything up. Averaging the peak frequencies during the single threaded runs comes out to roughly 4514.4MHz with PBO off and 4519.5MHz with PBO and AutoOC on. I have just started getting around to checking my performance with my 3900X. As of now we have them set on Auto, but have read elsewhere that you have to set them both to Enable in order for PBO to work. E.g. So now you have the best of both worlds, a 12 Core/12 Thread "Profile 1" for gaming and a 12 Core/24 Thread "Profile 2" for production work where you need the extra threads. We control all of these things as best we can, especially room temperature, but it’s still tough to fight. The 3900X is a very efficient CPU but it can suck down a huge amount of power (and generate a lot of heat) when asked to - up to 140W in default settings. Here are a couple excerpts. They just love extra clock speed.” We could test more combinations of boards and chips, but it just isn’t happening without completely changing the definition of PBO. Despite being a lightly threaded workload, it doesn’t seem that Total War benefits hugely from the 200MHz offset, but then again nothing else has either. But if a person has a top … Ok just another update have also played around with the PBO settings in the Bios and Im getting a nice boost from 4275Mhz to 4400Mhz consistently all cores on my 3900X while gaming, good cooling and a bit of playing around has definitely been worth it. Karena kemampuan Intel yang terkenal dengan overclocknya, performa i5-9600K mampu mengungguli Ryzen 5 3600X pada 9 dari 10 game yang ada. The improvement from PBO off to PBO/AutoOC on with the 3900X and a CLC on the MSI board was a whopping 2.4%, and 1.5% on air. After doing this, go to "Voltage Control" and set "Peak Core(s) Voltage to 1.3 Volts. In either case, the combination of PBO and AutoOC yielded improvements in some applications, but wasn't as impressive with the Ryzen 7 3700X as it was with the Ryzen 9 3900X. What matters far, far more is temperature, and even at liquid nitrogen temperatures the CPU increases its clocks just fine without any changes to PBO, and in fact PBO worsened performance due to a bug either on Gigabyte’s board or all X570 boards. Precision Boost Overdrive or “PBO” works the same as Precision Boost 2. Precision Boost OVERDRIVE is what AMD is calling it when those three thresholds are bumped up. Dezember 2019; e4syyy BIOS-Overclocker(in) 6. The limits that it’s raising aren’t limits that are restricting performance. Same with the low current boosts, I can be well below  the PPT, TDC, EDC and temp limits but my processor stops boost at Fmax (4.6Ghz) like it should. Gigabyte has similar BIOS wording to Asrock and correct me if wrong but Gigabyte has PBO settings on 3 different places, which is confusing. I mainly stream Apex Legends and theres kinda an unsharpness and u can see some pixel. Der offene Browser mit Stream macht ganz komische Sachen mit … Setup> advanced mode. I'm sure I could achieve slightly better clocks with a manual OC or with intensive testing of the Curve Optimizer, but for minimal effort, namely enabling PBO and setting limits to motherboard, I'm extremely happy with the outcome. We were maintaining up to nearly 4.4GHz all-core in Cinebench completely stock, PBO disabled, higher than the highest all-core overclock we could achieve with a 280mm CLC and all without voiding the warranty (PBO voids your CPU warranty, but dumping LN2 onto it and leaving it stock technically does not void the warranty, stupidly). For our final charts, we’d like to show some of the difference in power and frequency behavior with PBO on and off. Für pure Leistung geschaffen. CPU vcore -> normal CPU clock control 100.01 Settings AMD overclocking > Ddr and infinity fabric frequency/timings > if dividers > set this to half your memory clock. Considering that most of their 3900x and 3950x CPUs run at 145W, … If I allow precision boost to do it's thing, I hit a voltage of about 1.3 (CB20 score ~7400)  but EDC maxes at 100%. Facebook Twitter LinkedIn Reddit WhatsApp. This further reinforces our opinion on picking a case with good thermals, by the way, so now’s a good time to start watching our case review backlog. You would want to keep this percentage the same or lower than the Maximum processor state setting. Again, the run I presented was not with PBO as I stated right below the Cinebench run. Jetzt kaufen. The limits adjusted downwards (to spec) when a 65W processor was installed with PBO still disabled. Currently using the AMD Ryzen … Hier nochmal meine OBS Settings: x264 Preset: Medium Resolution 1536x864p (16x Bicubic Downscaling) (900p auch möglich) Bitrate 6000 Keyframe 2 Nochmal paar persönliche Tips:-Stream wenn möglich nicht über Twitch (Browser) schauen, falls ihr euren Stream nebenbei anschauen wollt - nutzt am besten die OBS Preview. We’re showing the peak core clock here because that’s the boost clock, which PBO/AutoOC is supposed to benefit, and because the average core clocks are even closer to identical. PC: MSI X470 GAMING PRO (MS-7B79), AMD Ryzen 9 3900X / PBO, MSI GeForce RTX 2080 Ti Duke OC 11 GB, DDR4-3200 G-Skill Ripjaws V 16GB x 2, Corsair HX 750 i, Windows 10 Pro on CT500MX SSD, Prepar3d v4 on CT1000P m.2 SSD. Default for socket AM4 is 90A on motherboards rated for 65W TDP processors. And i compared my OBS Settings with other People and … Electrical Design Current (“EDC”): The maximum current (amps) that can be delivered by a specific motherboard’s voltage regulator configuration in a peak (“spike”) condition for a short period of time. Geschaffen für den Sieg. The 3600 scaled 1.6% with PBO and AutoOC enabled on the Gigabyte board. At least not much, and certainly not for us. AW: Ryzen 9 3900x - Meine Erfahrung Habe seit heute auch einen 3900x und bin mit der Leistung eigentlich sehr glücklich. Hatte mal die Werte vom 3900x eingetragen die eigentlich total sinnfrei sind. First of all any and all settings in Ryzen Master under the heading "Default", "Precision Boost Overdrive" and "Auto Overclocking" are useless. AMD doesn’t guarantee AutoOC will actually increase clocks and PBO’s effect is inconsistent at best. ", cannot in good conscience recommend the AMD statement to him which, to me, appears to be a self-serving document allowing for a hypothetical over-volting of the system, to reach clock-speeds allowing it to be competitive, whilst at the same time stating that if you trust these documents and run your system in accordance with them then you void your warranty and if something goes wrong then you are SOL. With PBO or especially with Auto Overclocking the CPU gets way too much voltage whacked into it, and TSMC recommends 1.3 Volts as a maximum for its 7nm node and that's where I drew the line.Above that you just run into ever diminishing returns and you end up with a lot more heat than a higher score can justify.You also have to realise that silicon lottery is a thing, and I would be interested how far you could push your CPU manually if you limited it to 1.3 Volts.The thing is that I have gotten really cheesed off with so-called Ryzen configuration articles that are based on specific motherboards and BIOS and decided to write something that is useful to EVERYONE. The best result achieved for the 3900X was with PBO and AutoOC under a CLC, and the worst was with an air cooler and PBO disabled, but the gap is still so incredibly small. The effect on CPU clock speed is indirect, and PBO will never boost the CPU past the advertised clocks. Kann ich die CPU Manuell etwas … AMD’s Precision Boost Overdrive (PBO), for example, doesn’t boost clock speeds higher than what you see on the box. This website uses cookies. My aim is to use the processor with optimum performance without damaging or degrade it. Click on all the cores in CCD0 and CCD1 and set them to a speed and test that. The difference is still a miniscule 1.1% gain between the worst and best results, however. but in the end I am happy with the Asus Strix X570-E. :cool: ----- and now I need advice. We didn’t bother running more synthetics than Cinebench for this content piece because PBO is supposed to be primarily beneficial to gaming and because the run-to-run variance with Precision Boost was starting to drive us insane; we demonstrated why in our livestream, but will work on another content piece separately to drive it home. We have liquid nitrogen on hand, so it was easy for us to just dump some of it onto a 3900X and see what it would do under absolutely ideal conditions, stock or with PBO.
