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. 1; 2; First Prev 2 of 2 Go to page. At least not much, and certainly not for us. Whereas the 3900X typically ran at between 1.275 and 1.3v, the 3950X ran at just 1.150v, meaning the 3900X required around 13% more voltage on average. 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. Thermal Design Current (“TDC”): The maximum current (amps) that can be delivered by a specific motherboard’s voltage regulator configuration in thermally-constrained scenarios. Need help with my pc (3900x / asus C7H / noctua nh-u12s push & pull setup) Can someone explain this behavior? 3600 mem = 1800 in this menu. I will then use your feedback to update this post. temps constantly jumping from 45c-70c up and down Even in bios i get 60-65c , all settings on auto, enabled d.o.c.p , bios updated to last version (3103). Precision Boost Overdrive. Setting overdrive to “enabled,” setting overdrive to “advanced,” and specifying the motherboard as the source did the same thing on the two boards we tested for this content, but the two motherboards set different values. I have the latest bios from Asus site. I read a guide somewhere and set all cores to 4.5ghz and set a static voltage of 1.3v until someone told me Id possibly degrade my chip by doing that (had it … 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". Monitor: AOC CQ32G1 32" Curved QHD 2560x1440 VA 144hz 1ms Chassis: EVGA DG-87 Chassis Fans: 4x140mm Corsair ML Pro R G B Fans Motherboard: Asus TUF Gaming X570 Plus [Wi-Fi] CPU: Ryzen 9 3900x @ 4.25Ghz -0.1000 Vcore Offset. However, the speed increased only by a little: 0.39% with PBO, and 1.37% with PBO and AutoOC. Here are a couple excerpts. We did a lot of logging, but we’ve picked two runs as representative from the R9 3900X on the MSI Godlike board, one with PBO disabled completely and one with PBO enabled and set to motherboard limits with a 200MHz AutoOC. We’ve also used this setup to re-test the 3900X, 3800X and 3700X, updating the results where necessary. Precision Boost is enabled on a stock CPU, Precision Boost Overdrive is not. 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. If I enable PBO, my EDC only makes it to 63% of the new limit, (CB20 score ~7500). So I am sorry if you have been having a bad experience trying to make sense of what "influencers" who do get free stuff have confused you with regard to the ultimately pretty simple task of configuring your system for optimal stable performance. The warranty tells me that AMD has absolutely no confidence in its statement with regard to the silicon fitness monitoring of its CPUs. Build Name: Dark Dawn. 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. For a more logical comparison, the Godlike improved 2.5% moving from PBO off to PBO maxed with 200MHz AutoOC, but then zero single-threaded improvement. The 200MHz offset that’s mentioned in conjunction with PBO is called AutoOC. So I auto-overclock, and raise Fmax to 4.8 gHz. Editorial, Testing: Patrick Lathan Host, Test Lead: Steve Burke Video: Andrew Coleman, Keegan Gallick. On the 3900X, turn time completions were almost exactly the same regardless of the cooler or if PBO or AutoOC was enabled. Ryzen 9 3900x Trident Z Royal Gold - 32 GB 3600Mhz NVIDIA Geforce® GTX 1070 8GB So yeah i should upgrade my GPU but ill stream over x264 and not NVENC. 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. 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. This could be down to Gigabyte and we still need to replicate the behavior on other boards, but it’s bizarre either way. AMD’s Precision Boost Overdrive (PBO), for example, doesn’t boost clock speeds higher than what you see on the box. We failed to find a single game where enabling PBO and AutoOC made a significant difference, and PBO + AutoOC is intended to improve gaming performance. Shadow of the Tomb Raider showed no significant change based on PBO or AutoOC on the MSI board with a 3900X air cooler, air cooler or not, or on the Gigabyte board with a 3600. So which setting is it Auto or Enable, and if its not Auto then why, what does Auto do? TDC 60A. 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. Minimum processor state. TLDR; on 1440p+ with 3000 and newer Ryzen CPUs, limiting physical cores to your fastest CCD (chiplet) with good cooling will gain you higher frequency, especially with PBO / Auto OC. Setup> advanced mode. I managed to overclock my 3900X to 4.3GHz across all cores – a big improvement from the 3.9GHz I achieved out of the box, but still a little short of AMDs claimed 4.6GHz. 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. Note that we’re talking stock numbers with PBO as the A/B test, here, so all-core OCs are not part of this. What is the multi threaded Cinebench R20 score of "profile 2" configured as you described? The warranty tells me that AMD has absolutely no confidence in its statement with regard to the silicon fitness monitoring of its CPUs.". I mainly stream Apex Legends and theres kinda an unsharpness and u can see some pixel. 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%. He knows me and was thus willing to allow me to use Teamviewer to access his system, and was willing to spend the time with me to allow me to do the job right (which took over six hours of configuring and testing). Forget about trying to set up your system in the BIOS because that is a total mess and you are best off just leaving most of it set to auto (unless of course Auto does something silly such as setting the BCLK above 100). 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. It’s even smaller with the 3600 on the Gigabyte board. Der weltweit fortschrittlichste Prozessor 1 mit 12 Kernen für die Elite-Gamer dieser Welt. "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?". What he said, minus the settings I use on the XFR, PBO OFF and 1usmus powerplan. 3900X have better behaviour with a EDC 12~18 setting. Once It hit 1.325V or so on my processor, it stops boosting. Default for socket AM4 is 140A on motherboards rated for 105W TDP processors. $464 USD . ", 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. Results for the 3600 on the MSI board with PBO/AutoOC on and off were identical, and the results on the Gigabyte board were so close to each other that they may as well have been.
