You can set this to any temperature you feel comfortable with but I believe 90-95c is to be considered safe with your cpu. The CPU at stock performed well below expectations compared to online reviews and other users. Hello , I am trying to tune my 7600x performance using PBO. 213 votes, 45 comments. However, going higher on EDC or TDC creates an instant regression to something closer to 4. PBO Scalar: Set at 1, with a temperature limit of 90°C. I have been sooooo impressed with the 5950X ! Just finished dialing in PBO settings and got 4 cores reaching 5. Save and exit. Leaving that low also allows you to get more out of curve optimizer. However, I've tried messing with PBO, override +200mhz, scalar 4x, limits set to motherboard, didn't mess with any curve optimizers. First there is an Eco mode that limits its own boosting. I run with PBO and curve optimizer. Any higher and the curve makes it unstable. Higher the load, lower the voltage. PBO and static don't operate in the same way, PBO has dynamic voltage, it'll pull as much as it needs in given situation, topped at 1. Set it to kombo strike 3 and it sets all the pbo settings needed. Three settings, PPT, EDC, and TDC. I could not find any data supporting boosts this high for the 5900x. What is available now, in case of 5950x, is multiplier, bus (with different options), ram, and lots of different power settings. *stock ppt tdc edc and PBO at auto with -30 CO i meant. I'm fairly new to overclocking and would like to know what are yalls recommendations or experiences with overclocking the 5950x. The "motherboard" settings are causing major instability even when booting. My 5950x is over 47ghz all core at 3. 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. I was hesitant to try it but decided to give it a try. I have since gotten it close by using the following bios settings: PBO: Enabled PBO Fmax: Disabled FCLK freq: 1800 MHz (2:1 ratio with mem freq) DOCP/XMP: Enabled Max CPU boost clock override: 200 MHz Curve optimizer: -15 on all cores I have trouble adjusting my PBO limits; Anything above those settings result in instant reboots when facing multicore loads such as Cinebench R20. 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. Next is the power parameters that govern built in overclocking (pbo). My current one idles in the 50c range on a full custom water loop and hits the 80's under load. 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. (down from undervolt) Playing a bit more I found that having PBO limits too high actually decreases my score. PBO allows running the CPU with higher power and current limits, potentially allowing it to boost higher and longer compared to stock. Hi, I use 5950x as my daily workstation and would like to benefit with multi core workload. 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. PBO ADVANCED. I tried -10 which is stable 99% of the time but sometimes crashes in idle. 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. 7. 7% higher ave all-core speed or +317 MHz (mean 4,449 GHz vs mean 4,132 MHz) You're mixing up PBO with AutoOC. Roughly at -10 on good cores and -20 on the rest right now. PBO to advanced, PPT 270W, TDC 220A, EDC 220A, Curve Optimizer set to negative 15 to 17 all cores, Global C-state Control to Enabled, Power Supply Idle Control to Low Current Idle, CPPC to Enabled, CPPC Preferred Cores to Enabled, AMD Cool'n'Quiet to Enabled. 8ish max PBO settings (power limits, temperature target, v/f curve per-core) give superior performance and safety at the same time. Also I have PBO limits set to motherboard limits and scalar set to Auto. 5. ive noticed raising my EDC too much seems to limit single core to 4. Then watch some YouTube video on how to use PBO and do a custum curve and you'll have your 5950x pearling. tweaking PPT EDC and TDC ive seen some stray clocks over 5ghz here and there. 1ghz All core custom OC: 220w max power using 1. In R23 multi, I manage a 4. Get the Reddit app Scan this QR code to download the app now. PRECISION BOOST OVERRIDE aka PBO. 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. Max CPU Boost Clock Override: 125. PBO is a new beast. plus the deal was good, because i bought 5950x well below current MSRP. 45 GHz peak w/ 170W, 4. Inside your BIOS**,** enable PBO and select PBO advanced, this will bring up a bunch of options: PBO LIMITS. Precision Boost Overdrive : Manual. 8ghz on CCX1 and 4. For homelab use, stability is paramount, and the stock PPT value is 142W. . Feel free to PM me if you want of message on here, whatever First off, you need to locate PBO 2 in your bios settings. Only manual “overclock” is efficient but no dynamic high clocks. TDC Limit: 200. Help Request - CPU (MB X-570-e gaming) settings or my Do both! I have a 5800x. Don't expect amazing temps as the x3d chips run hotter because of the v-cache stacked on top of the die. 4GHz multi core depending on settings. 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. 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. This. But honestly, enhanced level 1 on my MSI does a good enough job compared to manual settings. Are these normal? I've switched to only doing my tuning in BIOS (no more ryzen master). Just straight OOB "optimized" BIOS settings. 2c I recently upgraded to a ryzen 7 5800x and very new to PBO2. But I am confuse with this procedure. Use "PBO Limit: Disabled", note down the numbers. ) PBO set to 200Mhz max boost. Should I just go with the stock PBO limits to start? I can just fire up ryzen master with stock pbo loaded, copy those down, and lock those in to start. 05-4. 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. 7GHZ. Seems like everyone with a 5950X is just using PBO from what I can tell. For a 32 thread processor, even a 5950X, you shouldn't be doing more than 1. Set 0. You're going to destroy that CPU's silicon with that voltage. It reaches 4. 8/4. There's loads to learn here but i will point u to a few topics. Avoid extreme PBO settings that could strain the motherboard components. Absolutely the same situation. Or check it out in the app stores 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. I currently have a B550i as my mobo. 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. 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. 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. But the temps are high anyway. If using PBO, don't touch LLC - leave it on Auto. 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. In my case bottleneck is definitely thermals: 24C room ambiant and Noctua NH-D15, CPU hits 90C and its game over. 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. I've read / youtubed explanations of the PPT / TDC / EDC settings. 156 +. Curve Optimiser: All cores -10. ) just maxed out CO in negative and reduced boost. The result was 29500 score in C23 which is far from all time high records but its everyday stable and Im fine with it. 27v. So basically top air cooler can unlock like 95% of 5950x potential for normal everyday usage. I wanna know peoples settings just to try different things, what needs on and off I’m used to intel much easier. 011v) and limited the settings to the same as the 5950x, just to see how it would compare. These are good settings to get a launch point from but the 5800x is a bit different for PBO power levels. 15v, peaking mid-70's) for multi core, slightly lower single core. If you keep trying to optimize settings you will keep seeing diminishing returns and hidden stability problems. In BIOS go to AMD overclocking, turn on PBO, set PBO boost override at +200mhz and set Curve Optimizer on all cores at -30. Which should be higher? 5900x. 5V. 45ghz and single core = 5. Here are some examples from OCCT tests. Dropping below these values will cause the system to crash mid render batch or sustained heavy workload. Everything else is on auto. 0% faster multi-ccore compilation (mean 53. If I set PBO limits to motherboard and start cinebench all core it instantly crash, can't turn off with power button, need to turn off power supply. Manually lowered these in BIOS and now never go past 75c on Cinebench. For better tuning look up the dozens of PBO or "curve optimizer" tutorials out there. It hits about 4. 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. 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. I've tried the BIOS on the support page and the beta BIOS on the forum (DLed last night). Single core stays the same at 4. 85ghz down to 5. You can use something simple like CinebenchR20 for a quick check to see if the settings are working properly. Even PBO can't seem to hit an all-core overclock of 4. My cpu cooler is an arctic freezer ii 360mm. 2 GHz when overclock and not much improvement undervolting, similar to PBO. ) Set the Digi VRam setting to Extreme. 97ghz in almost 6cores, 4. at least not enough to justify upgrade. 37 volts but ive been dabbling with PBO and i cant seem to find a stable middle ground. My system has the following hardware: MSI X570 Unify, 5950x, Arctic Liquid Freezer 2 360mm, 64gb 3600 CL14, Sapphire Nitro 6900xt @ 2. Use PBO2 tuner to set your CO curve instead of bios to save time. Although if you get the info from task manager it won't show peak clock speed for single core, just average across-the-board. Turning it off resolved the issue. I want to make sure I am not overdoing the PBO style overclock. ) Curve Optimizer set to per core negative 15. pbo settings are in Set PBO values to negative as down as possible (My Aorus Master B550 has -30). I did a quick and dirty undervolt on the 7950x (0. Curve optimizer tuned per-core negative offset, stable. 5 on my 5950x. 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. 0ghz, 3 of the cores reaching 5. No not pbo negative curve. 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. 662 GHz" My PBO settings are: PPT: 300W TDC:240A EDC:160A Besides the 547 MHz problem, i also want you guys to focus on the CPU VDD current (A): as you can see there was a spike on 265 A, which seemed really odd to me. 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. In the end I landed on all but 4 cores -25 and the other 4 can only do Edit: Resolved! Dynamic OC Switcher was Enables but settings were on Auto. rrkowz rolws bbls chaout haqbmc swwp wgjpff uwkec sppoootp tcn
