I'm still hunting for Curve Optimizer stuff. I was hesitant to try it but decided to give it a try. 46v during load, ~0. PBO Issues. Jul 30, 2019 · So I was tinkering with PBO on my 5950x for the first time tonight, nothing special just tweaking PPT, TDC, and EDC limits, everything else auto. Recently bought a Ryzen 9 5950x (running it on stock PBO off) and pairing it with an RTX 3080ti. Are these normal? I've switched to only doing my tuning in BIOS (no more ryzen master). Have a Kraken Z63 cooler and a X-570-e gaming MB I'm not saying it's necessarily wrong, but a 5950x with PBO enabled comes neck and neck with the 12900k. I think it may mirror the applicable settings to the Extreme Tweaker section after you save the bios settings and reboot. 75 in ST. Clear ram settings, load xmp stock settings and run corecycler again. Ram settings is the problem. Actually improved my single-thread score, probably because less heat allows PBO to boost higher. PBO Scalar: Set at 1, with a temperature limit of 90°C. Perfect. Not that saved profiles kept any PBO settings anyway for some weird reason (AsRock x570 Creator). 2 GHz when overclock and not much improvement undervolting, similar to PBO. Hey there! You helped me before with my 5950X. Precision Boost Overdrive : Manual. 6ghz all core and temps for like 50°c so I went to bios and googled most people were saying "set all core -25" immediately crashed. Also this bad boy hits 5050 Mhz on 2 of its strongest cores with everything on auto, multiple ones hit 5000, and EVERY single one hits 4. Set everything to auto except for the "Thermal throttle limit". 45GHz in Cinebench MT and about 4. ) Set the Digi VRam setting to Extreme. 1ghz pretty much. But the temps are high anyway. I don't think it's fun. I could not find any data supporting boosts this high for the 5900x. Being able to stress test PC components, track progress and have a leaderboard all in one is a dream tool for overclocking, especially for those who seek daily stable settings. 5V. (down from undervolt) Playing a bit more I found that having PBO limits too high actually decreases my score. Run Cinebench again and your scores should now be normal. Hello , I am trying to tune my 7600x performance using PBO. İf your 5950x only hits 4. I did a quick and dirty undervolt on the 7950x (0. 45v idle. -5 all core yields almost 29k CB R32, which is good enough for me. Single core = 4. 25 and gets 32k r23 currently I can go higher but I’m still getting the e soc and memory voltages right to for stability above 4. Re-enabled my PBO settings that was getting me 5GHz on 6/8 cores, and 643 single thread in CB20. Yeah other than RAM related settings for tightening timings, PBO settings are the only settings I’ve messed with. My 5950x was running with the usual optimisations, PBO on with some custom settings to limit heat and power a bit while undervolting the cores (per core) to get some decent performance out of it. Enable PBO, leave Scaler on Auto but put 200Mhz on 'max CPU boost clock override'. *stock ppt tdc edc and PBO at auto with -30 CO i meant. No not pbo negative curve. So, I am struggling with finding the best settings for the x570 BIOS with the 5950x. Using optimized settings compared to stock settings. Enable it in BIOS (more reliable in my experience) or in Ryzen Master and you're done. 5. My PBO motherboard limits were insanely high, causing my 5950x to peg 90c almost instantly on Cinebench. Multi core = 4. Use PBO2 tuner to set your CO curve instead of bios to save time. Dropping below these values will cause the system to crash mid render batch or sustained heavy workload. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. TDC Limit: 200. 85ghz down to 5. Manually lowered these in BIOS and now never go past 75c on Cinebench. at least not enough to justify upgrade. Hello all, I have had my 5950x for a few months now and can’t decide whether to use PBO or an all-core OC for my use case. Msi has a specific setting called "kombo strike" just for the 5800x3d. Then in the AMD Overclocking setting, I enabled PBO, set my curve optimizer, adjust tdc, edc, ppt, scalar, etc from there. Now keep in mind some fold with gold silicon are able to still get -30 on 5950x. and now I have changed to -30 all core, with 50Mhzboost, PBO limit motherboard (not done any fine tuning (per core setting with lower value for best core e. PBO has better single core, slightly lower multi core, but better overall scores in combined tests. PBO is a new beast. 25v for a manual OC because when you change the CPU multiplier and voltage, you prevent the Silicon Fitness from doing its job, and it's there to protect the CPU from itself. However, going higher on EDC or TDC creates an instant regression to something closer to 4. PBO is awesome for benchmarks but i found for day to day operations its completely unnecessary and it actually lowers performance in regular apps. do you guys think an all Get the Reddit app Scan this QR code to download the app now 5950X PBO/CO settings question/check . It reaches 4. 1Ghz Power - 145W Currents - 130A average And sat comfortable at 68c with a high of 71. This leads me to believe that maybe I have a bad CPU sample in the silicon lottery where it can't OC as high as average. PBO peaks at ~1. That should give you pretty close to the highest clocks you can get with PBO (PBO has it's limitations and it will radically limit your CPU performance because it simply overvolts the CPU), if your cooling keeps the CPU below 80-86'C tdie with the above settings, you can start to increase your EDC until the EFFECTIVE clocks start to drop. 1-4. If you keep trying to optimize settings you will keep seeing diminishing returns and hidden stability problems. Most educated users would enable PBO. I was totally perplexed why light loads would sometimes crash on my 5950X (just the app not even BSOD) but heavy loads were rock solid stable for extended periods of time with aggressive memory overclock, maxed out PBO settings and -22 all core curve optimizer (first value I tried). If it you think it wasn't the case, try increasing the PBO values of the power-eating cores (cores which has the highest minimum voltage during #1). I ve scored higher under other PBO settings but the thermals were in the 80s. I have a new chip now though because my old one had bad cores and would crash even on stock. My cpu cooler is an arctic freezer ii 360mm. If I set TDC to 133 and EDC to 150 in BIOS I get a score of 23100 in cinebench r23. . If I set it to something way higher in BIOS and limit it in ryzen Master to TDC 133 and EDC 150 I get like 23700 score. Power limits are whatever the defaults are. With pbo on at default settings is 24607 multi thread. etc. Turning it off resolved the issue. Then stress test and make sure its stable. 011v) and limited the settings to the same as the 5950x, just to see how it would compare. I've tried the BIOS on the support page and the beta BIOS on the forum (DLed last night). Here are my settings: Power settings: 200/180/150 Scalar: 2x Override: +75 CO: -7 All core XFR: Enabled However, I feel like my benchmark scores can definitely be better- especially single core. Leaving that low also allows you to get more out of curve optimizer. 1. MAX would be 45°C coolant temp, which will be reached when I also turture my 2070 Super with 260W at the same time. Sure it is! Bios, Amd Overclocking menu, PBO options. Raising your EDC can raise your temperature, so yea you can see slight temperature increase. PRECISION BOOST OVERRIDE aka PBO.

Change PBO to advanced and increase all the sub settings to the highest. PBO ADVANCED. Finally I desperately tried tweaking every possible PBO setting and noticed turning off thestilts PBO Fmax Enhancer would cause my chip to boost to 4. Make sure OCCT is set to single core. Then watch some YouTube video on how to use PBO and do a custum curve and you'll have your 5950x pearling. hey guys, just curious for some extra knowledge on overclocking a ryzen 9 5950x. Which should be higher? 5900x. Quick disclaimer: I'm a complete noob when it comes to overclocking, and don't have huge amounts of time for heavy curve optimization, so I'm just looking to try and get back to how the CPU was behaving a few months ago with PBO enabled and staying on it. 5GHz @ 1. First there is an Eco mode that limits its own boosting. 27v. 125Ghz. Your ASRock AB350 Pro4 has 3 power phase and the motherboard components will run HOT and potentially burns itself, damaging the CPU and socket if you're not too careful with the temperatures and PBO's TDC/EDC settings. Only set pbo enable exit that go on cpu voltage enable offset mode negative and press minus key. Hello, I have a X570 i aorus and 5950x with liquid freezer 2 280mm and fans set to 100%. 5) max. 5950X PBO 300 230 230 AutoOC 100, max temp around 75c. 4. Set small data set, SSE, variable load, and set affinity to the core you're testing in Task Manager (mark both threads). 8 single core boost. When I have just PBO alone with no manual overclock, on max load, my system becomes less responsive (cursor lag). 65GHz all-core compared to ~4. 6/4. There's loads to learn here but i will point u to a few topics. Try to find a simple instruction for your specific BIOS, here are general tips for several bioses I found: GIGABYTE -> Advanced settings -> Settings -> AMD Overclocking -> Accept disclaimer. Even PBO can't seem to hit an all-core overclock of 4. Save and exit. 5Ghz sustained clock when testing R23 MC, and when testing SC the best core sees 5. The "motherboard" settings are causing major instability even when booting. I set those three PBO limits and removed curve optimizer undervolt settings (kept 10x and 200mhz boosts) and got like 4. 7GHZ. I am getting certain cores hitting 5. does it make more sense to leave the settings with PBO on in combination with this restricted thermal throttle limit or am I missing something With my PBO settings tuned I got all core 4. In my prior tests, through the Advanced PBO OC menu, I adjusted PPT, TDC, EDC and Curve Optimizer starting with the stable settings I had for 2 years, with and without XMP profile (no tweaking here). Things will probably change as more betas come out, but I’m pretty happy with where it’s sitting now. Then change to "PBO Limits: Manual", set PPT to 200 and bump TDC, EDC by 10 at a time until you reach a desired max temp / performance. 4GHz multi core depending on settings. R23 last I checked was 15423 and 1598. For my 5600X PBO it makes my CPU go up to 4. Also various settings between -5 to -30 per core undervolting. However, when I turn on PBO just to set an all-core undervolt of 15 increments, things go up to 4. CO and FO wise, needs testing, but generally, for gaming, +100MHz and a bit looser CO may be better than +50MHz and tighter CO. Motherboard has a 10 phase 40amp vrm, which means its MORE than capable to provide 180-200W for a 5950X. I don't if PBO is in the scope of this subreddit, remove if so, sorry in advance At defaults settings and full load, frequencies are likes this, actually 5900x one steadily stays at 4500mhz most of the time Weird things is in 5950x build package temps are higher, in 5900x core temps are higher. ) Curve Optimizer set to per core negative 15. The work's already been done for you, and the 5950X is extremely efficient out of the gate. For those of you starting out, here's most of my CPU OC settings (roughly in the order they fall in the Asus BIOS): CPPC: Enabled CPPC Perf Boost: Disabled Core Perf Boost: Ena Boost Override: 200 MHz FMAX Enhance: Dis AI OC Tuner: Manual TPU: Keep Current Settings CPU Load Line: L1 Active Frequency Mode: Dis VDDSOC Load Line: L1 Power Down Enabled: Dis Eco Mode: Dis PBO: Manual PBO Limits Overclocking Settings: PPT: 229 TDC: 160 EDC: 157 Boost Override Clock: 200 MHz Curve Optimization: I began with just the PBO enabled, default settings, and ran Cinebench R23 Multi-Core and Single Core tests to determine maximum boosting cores. Don't expect amazing temps as the x3d chips run hotter because of the v-cache stacked on top of the die. And 2: dont know how dynamic oc works,being an Asus dark mobos exclusive,but from a 1 minute search on internet, it helps a little in single core perf. Or check it out in the app stores &nbsp; r9 5950x PBO settings for low temps and good gaming perf We would like to show you a description here but the site won’t allow us.

However, I wanted to get the PBO/PBO2 settings configured again after resetting the BIOS but nothing I seem to do seems to get any cores to boost over 4,500mhz now? I tried setting the Performance Boost Overdrive settings in the Extreme Tweaker section, to the following: PBO FMax Enhancer: Enabled. When you're done testing all cores, test with medium, SSE, extreme, all cores. Memory benchmark and leaderboard is also available (scroll down). He's using an inwin A1, 3 intakes 1 exhaust & hitting 90 with standard settings, enabling PBO and dropping PPT to 100w drops that to about 85c but it's still quite hot. Boost Clock Override: Applied a +125 MHz increase without significant impact. Sleep mode / CPU scaledown is still enabled so it'll peak straight to 4. The only mobo changes I made were enabling xmp profile, enabling PBO, and adjusting the fan curves to be slightly more aggressive (I have 2 Noctua 140s in front for intake and a rear Noctua 120 for exhaust in addition to the Arctic fans). PBO allows running the CPU with higher power and current limits, potentially allowing it to boost higher and longer compared to stock. Surprisingly terrible 5950x PBO results I've been running my 5950x at stock for a while now, with it boosting to 4850mhz every once in a while, and idling at around 95w @ 58c. I have mine set at 90c. ive noticed raising my EDC too much seems to limit single core to 4. I found soc and memory voltage are more important to oc my 5950x Have it advance with those PPT/TDC/EDC settings in my MB and curves don't see to help much with the mhz. This. I tried changing the cpu LLC to level 2 and the EDC quickly went up to 98% so I rebooted and set it back to auto, aftwr which the settings went back to 85~95% EDC and creeping higher Just don't use "PBO Limit: Mainboard" those are MOBO limits which are often ridiculously high. PBO Scalar: Auto. e. 3ghz all core and like 4. Apr 15, 2021 · PBO is pretty much just a toggle. PC kept freezing within minutes, no matter what combination I used. 775, but higher multi core scores and same single core scores. i know its overkill but i mostly game on my rig and sometimes i stream, currently running the 5950x, rog crosshair viii extreme MB and corsairs h170i 420mm AIO. 37 volts but ive been dabbling with PBO and i cant seem to find a stable middle ground. So in the long run. Try simple auto voltage or AMD overclock, not PBO. It hits about 4. I've read / youtubed explanations of the PPT / TDC / EDC settings. The cpu package wattage is 224 while running cinebench r23 with PBO on default no Curve optimizer is this normal or is my cooler not functioning correctly. 1: there aren't a fixed set of settings for pboenable it, set pbo limits to mobo, use core optimizer/ per core ,use ryzen master to see cpu behaviour in benchmarks- i. Making a negative curve will cool your CPU but that allows more room for your 5950x to boost even higher and that is the method behind pbo. 5950x 5950x has best bins for all core load. Everything else is on auto. Max clock went from 5. They will pretty reliably boost to 5050mhz without any at all. Voltages on PBO and on static OC can't be compared. My 5950X hits R23 score of a little bit over 30K, 160TDC/180EDC/270PPT and tuned CO, yadada. It crashed for weeks randomly between like half a day to two days and I kept changing things and it was working for like 4 days straight then I just replaced the thermal compound with liquid metal (barely noticeable) and the bios lost all settings. 5C with highest clock speed at 5075MHz, let me know your thoughts, cheers. The above results were stable enough for benchmark runs, and appeared on the surface to be stable in games, but only playing a variety of games over a longer period of time will truly reveal whether or not your settings are 100% stable. For better tuning look up the dozens of PBO or "curve optimizer" tutorials out there. 7. Precision Boost Overdrive : Manual I'm running my motherboards default pbo settings and am hitting nearly 90 c about 88c in a 10 minute run of cinebench r23. The up to +200 offset is AutoOC. 025 Each core was averaging 4. 03 or what your sistem put default and increase that number after a sistem test ntill you get to a "normal" temp not 90;) If you play with negative curve in the pbo menu your cpu will get hotter;) I have a Asus Crosshair MB and a 5950x with Kracken X72 cooler. And now I can’t even get that again. MSI X570 Unify, 5950x. 3x side and 3x bottom fans intake. From my understanding the 5800x is a bit hotter and the max stable curves are a bit lower since the 5950x is better binned. 553) 7. But I am confuse with this procedure. But honestly, enhanced level 1 on my MSI does a good enough job compared to manual settings. Single core stays the same at 4. Any higher and the curve makes it unstable. If it's using more voltage for the same frequency and level of stability then it simply hasn't been tuned correctly. Higher the load, lower the voltage. Inside your BIOS**,** enable PBO and select PBO advanced, this will bring up a bunch of options: PBO LIMITS. It seems like there is a difference settings PBO limits in BIOS and setting it in ryzen Master. I have pbo on and curve optimizer -25 all cores. Just with PBO enable during all core cinebench temps are 57° and 4 ghz and 26 264 score. 45 GHz peak w/ 170W, 4. my max OC for all core was 4750mhz @ 1. Hello everyone My temperatures are a bit high depending on what I play for example in Horizon Zero Dawn I see up to 78º depending on what situation, in cyberpunk about 75º (Noctua NH - D15 dual fan) i see videos of people playing the same games with same specs and similiar coolers or even worse ones and they get like 50º playing horizon or cyberpunk i cant uderstand that xd I've noticed that with PBO enabled (I only have PBO and not curve optimizer in my BIOS), the larger the negative voltage offset, the better the multi-core performance becomes. Let me know what settings yall running in terms of what CPU vcore, what PPT/TDC/EDC, PBO advance settings, etc. You're going to destroy that CPU's silicon with that voltage. 5950X Stock, max temp around 68c. It happens to be found in the PBO menu, but it is not actually part of PBO itself and can be run independent of PBO. For homelab use, stability is paramount, and the stock PPT value is 142W. The CB23 scores are below: All threads: Stock: 25390 Offset -0. Hi, I use 5950x as my daily workstation and would like to benefit with multi core workload. After saving settings if you encounter crashes dial Curve Optimizer to -28 and check if stable again. I got my 5900x a few months back, but I couldn't run pbo, got weird result with stability, what I did was just set everything on auto, with a xmp profile of 4000mhz at first I thought my ram was causing problems but them went back to 2600mhz and still getting crashes, i let everything on auto cause my chip was going easily up to 4. Various settings from 118-125-stock ppt, 75-90A TDC and 115-140EDC, with the lowest settings there giving best results in cinebench. 05-4. Score 28,500. Max CPU Boost Clock Override: 125. Set Curve Optimizer to -20 across all cores. 65GHz. ) Enabled FMax enhancer 3. I feel I have a handle on some core concepts of the undervolting process / testing using negative values in the curve optimizer, however I'm still fuzzy on the PBO Limits and scalar. I get so many variations in my scores plus getting 13k cpuz makes me hit 90. Just straight OOB "optimized" BIOS settings. Cinebench r20. 97ghz in almost 6cores, 4. Roughly at -10 on good cores and -20 on the rest right now. PBO can go as high as static OC, within reason. I wanna know peoples settings just to try different things, what needs on and off I’m used to intel much easier. ASROCK -> Advanced -> AMD Overclocking -> Accept disclaimer -> Precision Boost Overdrive Under idle on my custom settings within Ryzen master the CPU idles around 32C, on the default stock CPU profile the 5950x idles over 60C. Not even joking. That alone may be enough for your needs. 200V, but my present PBO/CO setup manages 4500mhz all-core while maintaining ~4900mhz boost on any of the 16 should any one core get hammered by itself. My final parts are arriving soon and I'm prepping for undervolting the 5800x CPU. 8 on the rest and 4. 8ghz After months of playing with PBO on my 5950x and finally finding the perfect configuration AMD released the CPU tuning in the Radeon Software. Can you send me your current CO settings and current PBO limit settings? I want to try PBO on this new chip. These are updated results with my daily, game-stable settings: [Settings] Clocks, 500-3050 My 5950x is running on a 99$ cheapo b450 itx board with 160 tdc and 190 tdc and it's hitting current limits but I doubt a 5600x will do so. Set it to kombo strike 3 and it sets all the pbo settings needed. for everything but gaming. 0% faster multi-ccore compilation (mean 53. Here's what I came up with. Anyone have additional tweaks or resources they can point me to to mess around? 7950x w/ PBO undervolt by 100mv, 32gb DDR5-6000 EXPO CL30, Kraken X72 (without AM5 brackets), Gigabyte Master X670. Now I am getting better scores (around 28000) and the cpu clocks are around 4 Ghz. Skip this for the first #3 run. Usually 5950x settles at PPT 280W, TDC 150A, EDC 190A, but games will require a bit higher TDC and EDC (by 10-20A). I've set PBO limit to motherboards, I've choose CPU TDP config to 105w ( it make PPT 142/TDC 110/ EDC 170) I've set Boost Clock Override to +200 Thermal Limit untouched From what I understand, PBO boost until one of those limits are reached. plus there is like a 10c temp increase. EDC Limit 150. there is no difference in gaming between 5950x and 5800x. I currently have a B550i as my mobo. Trying to hand-tune PBO2 and am hitting a wall. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon… Turn PBO on, setup a negative offset in curve optimizer, and tune the power limits - all of which is under the PBO menu. I am mainly looking for recommendations for longevity of processor with maximum benefit in terms of performance. In BIOS go to AMD overclocking, turn on PBO, set PBO boost override at +200mhz and set Curve Optimizer on all cores at -30. 5950x's don't really need much if any boost override. I have spent the last three days figuring out what settings was causing the issue and these two I mentioned seem to be it. 5950X PBO 300 230 230 AutoOC 100 Curve Optimizer -15, max temp 81c. ) just maxed out CO in negative and reduced boost. gaming doesnt use all cores. For a 32 thread processor, even a 5950X, you shouldn't be doing more than 1. I did not spend a lot of time tuning settings. If using PBO off, my chip can go -7 for all cores, PBO Auto -3, and -1 is all i can do PBO @ motherboard limits through a couple of AGESA revs on my particular 5950x. It seems to apply all of the settings correctly this way. 4 down at <1. You can use something simple like CinebenchR20 for a quick check to see if the settings are working properly. 8ish max PBO settings (power limits, temperature target, v/f curve per-core) give superior performance and safety at the same time. Here are my settings so far: PBO Limits: Motherboard Curve optimizer: Per Core Negative 15 on all except for Core 3 and 7 which are the star cores from Ryzen Master I spent the day tweaking bios settings hoping to find what was causing the subpar performance, thinking it was something to do with power restrictions. 3ghz, and full default hangs out in the 4ghz neighborhood. 900. 8/4. 2GHz when stock. To overclock a cpu without pbo, with an old-school way, you just increase the In AMD Overclocking: PBO set to manual PPT 270W TDC 150A EDC 170A, Scalar X1, Frequncy Override to auto Next you need to tune Curve optimizer per core, set Curve Optimizer to Per Core, set all cores prefixes to NEGATIVE and set all numbers to 15, so, basically all cores will now run at -15. 3X Radiator fans are set on push config mounted on the top on a Lianli PC-O11 Dynamic XL. However, from posts I'm gathering people having TDCs at up to 220A so I'm wondering if it's really that bad of an idea to increase it manually. My 5950x is over 47ghz all core at 3. I tried PBO with a -20 all core on curve optimizer and set the thermal throttle limit to 70 degrees. Get the Reddit app Scan this QR code to download the app now. I want to make sure I am not overdoing the PBO style overclock. My current one idles in the 50c range on a full custom water loop and hits the 80's under load. PPT/TDC/EDC: 230/150/150 Scalar: 4x Boost override: +50mhz CO: -12 all cores Keep in mind, I'm prioritizing stability at the moment. ) Enabled PBO 2.
