Ryzen CPU like a 7700 has a TDP of 65W. robman501154002d7 Active member. Some say set the limits to "motherboard", some say set to "disabled" and some use "advanced" but that is waaaaay too technical for me. The only limitations of PBO are hard limits set by the VRM's and other power regulatory components. You can use PBO Limits settings to unlock the power limit of the CPU to unlimited. In much the same way, raising the boost limit can paradoxically reduce performance. The idea was to obtain an average per core VIDs "calculated" by SMU without implicit restrictions applied. then you want to turn on the PBO Scalar to 10x as this will allow the CPU to boost for longer and it will add more voltage for the CPU to boost higher. Temps only reached 74C max during each run. If I disable pbo limits I get 4. Default limits are TDC/EDC/PPT of 95/140/142, these are 95 amps when thermally constrained, 140 amps normally, and 142 amps from the socket Motherboard: Gigabyte Aorus X370 Gaming 5: Cooling: Cooler Master MasterLiquid ML240L V2: Windows 10 Professional (64bit) Benchmark Scores: RIP Ryzen 9 5950x, ASRock X570 Taichi (v1. fr/mvvj3a: Nov 15 Difference between PBO Limits: Disabled, Motherboard, and Advanced? Thread starter robman501154002d7; Start date Aug 18, 2023; R. LLC: Level 1 (not sure if necessary) I enabled PBO and just set motherboard power limits. PBO is a feature built into PBO (Precision Boost Overdrive) is essentially that thing that makes your Ryzen CPU boost above it’s standard clock. The PBO curve is set to -15 and the PBO limits are disabled, I followed a Youtube guide that said PBO Limits Disabled means that the limits are set to the CPU's own stock limits. The limit most important is temperature. craxton · Registered. Observe TDC, EDC and PPT PBO 1 or PBO 2 etc don't use AMD set limits, but motherboard vendor limits. Windows 10 home 64: Benchmark Scores: Superposition 8k 5267 Aida64 58. ” 4. A MSI Godlike or Asus Extreme motherboard will have vastly higher rated VRM's compared to the uber budget mobo's, so can deal with higher PBO power In the bios I set PBO Advanced settings PBO Limits to Motherboard, PBO Scaler to Auto, Curve Optimizer to negative 30, 30, 8, 30, 30, 30, Boost Override to 0, 50, 100, 200; and Thermal Throttle limit to Auto. Is this true? I've been seeing all sorts of answers to this I would really apprecaite some insight. are too important. So, what's the simplest way to put it for Pbo limits set to disabled keeps the 3 values at factory limits defined by the cpu, set to motherboard for crazy high limits set by the mobo manufacturer related to vrm supply limits, set to manual to define your own. Hey there so I'm running a Ryzen 5 5600 (non x). Running Prime95 small FFTs on all cores, from 3. Joined Mar 1, 2022 Messages 340. g. and no dip in performance. I'm getting some of my best all-around benchmark scores. 10v offset. Then if that’s stable start messing with curve optimizer. PBO = soft power limit set by motherboard/bios vendor. Save Share Reply Quote Rep+ . PBO Limits Auto or Disabled? Hey there so I'm running a Ryzen 5 5600 (non x). 5ns: Oct 30, 2024 I wanted to know the effect of setting PBO limits in real time, so I played with them and watched my clock speed. Why different behavior from PBO limit "Motherboard" + Ryzen Master to PBO limit "Manual" + same defined values? Additionally after Ryzen master does its first reboot with profile and applies settings. Setting PBO limits to motherboard or manual, means the CPU can draw as much power as it wants, which naturally leads to a nice performance boost, at the cost of the max temperature going up by 10-15 degrees Celsius. Now if you google what it is, AMD describes it as a The limits that PBO raise aren't the limits encountered in testing/gaming (unless you are using liquid nitrogen). Test in Prime and R23. Are all these 5 results from the same motherboard and Windows 10 ? AMD Ryzen 7950X3D / 2x32GB Hynix Raise EDC/TDC by 5-10%, test again - or drop them by 5-10%, test again etc for best results. Onyx: A MD Ryzen 7 7800x3d / ASRock Taichi 7900xtx OC / Gigabyte B650 AORUS Pro AX / G. Update: I've downgraded the bios and checked with both the last version of Ryzen master (2. Perhaps, IMO, temps. Increasing PBO limits already gave nice all-core clock increases. 0) Professional 64-bit: Benchmark Scores: https://valid. 0. Those are general rules for Ryzen 7000, the like 8 AM5 systems I've built, including a 7950x3D, all didn't mind those settings at all from the rip. If you are not hitting 100% of the power limits, raising them by bios or Ryzen Master isn't going to By setting the limits to the motherboard option you are loosing performance - I recommend setting the limits manually. 575 if temp is max 71C. x86. Observe TDC, EDC and PPT values and check what % of the max you are hitting. In cinebench at 76W ppt I get allcore of 4. Then set the scalar to somewhere between 7x and 10x Do make sure you have a great CPU cooler to do this. high current) and up I posted this before on reddit about a month ago - edited so it makes sense here- hopefully it helps - I have the Dark hero but trying to change the tdc edc ppt limits in the amd overclocking section of the motherboard wouldnt actually result in those limits raising - my edc/tdc/ppt limits would changed if I altered them in the extreme overclocking tab (same the highest score was when PBO limits set to motherboard same as the pic above i'm running on windows 10 pro I got a better score i set Pbo limits to mobo And a negative offset all cores 25 Scored 22347 but temp reached 79C Link to comment Share on other sites. Win 10: Dec 8, 2019 #1 Start video at 45:30 In the picture below I simply entered maximum rating which would be impossible for the CPU to attain making the PBO limits functionally disabled. Then, I set -0. , if I look them up in Ryzen Master). 0ghz Precision Boost Overdrive: Precision Boost Overdrive (Disabled) & PBO Max enhancer (Disabled) VDDCR careful with the scaler settings, it *could potentially* lead to shorter chip lifespan according to "the stilt" " The seen behavior suggests that the full silicon reliability can be maintained up to around 1. Non PBO = hard power limit set by AMD. 3 ABBA BIOS. Is there "motherboard" in a "PBO Limits" submenu on your board? Per core temp sensors are in the latest HWInfo beta. Letting the motherboard take control of the overclocking is more efficient with power management, but potentially not the best in terms of maximum Then set the PBO limits to “Motherboard. Place to discuss Windows Mixed Reality The power limits for default PBO is very saddening. 65 GHz for AVX2 (almost 10%). Simply setting PBO to “enabled” scored 3748/485, and setting PBO to motherboard limits (functionally the same as max), maxing throttle temp and PBO scalar, and applying the AutoOC 200MHz In the advance section of PBO, set PBO limits to motherboard or manual and set values that you won’t realistically hit. Oh and fun fact limiting EDC to something silly like 10 completely breaks PBO on my board, giving me silly 4525 mhz all core boosts while gaming. Question Windows 10 / 11, With 3x PCs Different Properties and peripherals (AUDIO CRACKLING/POPPING NOT FIXED IN OVER A YEAR) Latest: The Great Buran; 7 minutes ago; By setting PBO limits to Motherboard, I read on HwInfo the limits being 395W/255A/200A for PPT/TDC/EDC . Factory PBO just sets the limits at AMD set limits, which raises the range of what the Ryzen deems as tolerable. 2 Chipset Drivers: Not sure sorry PBO Limits [Motherboard] Precision Boost Overdrive Scalar [Auto] Curve Optimizer [Per Core] Core 0 Curve Optimizer Sign [Negative] Core 0 Curve Optimizer Magnitude [30] Phanteks NEO Qube | OS: Windows 10 Pro / Optimum tech's video is mostly an undervolting guide , rather a full OC guide with PBO. Set PBO to +200MHz and -15mV all core. Unless Under EXTREME TWEAKER where the Options are Enabled/Disabled/Auto/AMD ECO MODE. 7. PBO 1 or PBO 2 etc don't use AMD set limits, but motherboard vendor limits. I'm on 1. i have tried all settings But once in windows again high temps and high power consumption no ECO MODE Set PBO limits manually (set to manual instead of Auto or Motherboard): PPT Limit: 88000 TDC Limit: 75000 EDC Limit: 150000 . to get the most out of your Ryzen 5000 CPU is you need to do is set your Manual PBO Custom Limits or select Motherboard option. You shouldn't buy this motherboard if you're not going use the extended power ranges and controls the motherboard hardware provides. The default limits for 105W CPUs: 142W PPT, 90A TDC, 140A EDC. B550 gaming edge, 5800x, 5600x, 3600xt, 1600AF, 4070t, 4x8 3200c14, 2tb adata 8200sx PRO, 500gb PBO Limits Set to: Motherboard Scalar Set to: Auto Curve Optimizer Set to: Disabled Max CPU Boost Clock Override Set to: +200Mhz My scores for Cinebench R23: SC: 1576 And there is a fair chances to corrupt your OS while doing this, so you might have to do a clean install of Win or what you are using. 5) and with bios F31 from May 2019 I can set the PBO limits to 700 380 440 and apply them, but the CPU seems to have the limits from the newer bios (300 114 168) burned in, even with EDC 440 it still stays at 37%, 168 A. my motherboard is ASUS Strix B550-F Wifi II Here's my bios settings ---A. I then went back to Windows 10 and tweaked more of the bios & gpu settings and minimized the stuttering. Find the Precision Boost Overdrive scalar controls, and set it to Manual. e. SETTINGS: I have PBO settings maxed out in the BIOS: PBO: Advanced PBO Limits: Motherboard PBO Scalar: 10X PBO Boost Clock Override: 200MHz Platform Thermal Throttle Limit: 255 CURVE OPTIMIZER: Negative 20 all core. Once you do this, boot into Windows, open Ryzen Master and start CB23 multi thread test. 330V in all-core workloads (i. I Tweaker Tab--- DOCP: Enable CPU Ratio: 40 or 4. For +200 pbo core 0 needs -27, core 1 -29, rest do -30. In the advance section of PBO, set PBO limits to motherboard or manual and set values that you won’t realistically hit. 0 1300W | Cooling: Heatkiller IV CPU block, 2 x Alphacool NexXxoS UT60 Full Copper From what I understand, A PBO negative offset undervolts the CPU. If y Motherboard: Asus X570i: Cooling: EKWB 240 AIO: Memory: 2x8gb 3200 Mhz: Video Card(s) AMD Midnight Black 6800XT: Is it currently possible to set a limit to PBO's maximum boost frequency? A manual negative frequency offset if you will? Microsoft Windows 10 (10. As a rough guide for this, if your CPU is sitting at the boost limit during a cinebench 1T test, i would bump it 50mhz and try again. PBO set to motherboard: 2: 5/6-10: PBO boost override to 0. PPT is the power drawn from the socket, TDC is sustained current limit drawn from the VRM, and EDC is the peak current limit drawn from the VRM. 2 AM4 mATX BIOS Version: Don't really know sorry Corsair Carbide Series SPEC- Delta 650W 80+ Bronze Tempered Glass RGB U Operating System & Version: WINDOWS 10 PRO GPU Drivers: 23. So I've reinstalled Windows 10, literally took 4 minutes I set PBO Limits to Motherboard, and Negative all cores 30 , its stable from what I can see. 625-4. Motherboard: Asus B450M Dragon 4400mhz(OC) M. I got OCCT errors in Core 2 down to -8, all others were ok at -30. Set PBO scalar. 36 GHz to 3. In Prime95, I get around 84C for 5-10 minutes. Operating System: Windows 10 21H2 | Monitor: Iiyama ProLite XUB3493WQSU. Change the curve optimizer to negative and go as low With PBO, you can unleash the true potential of your CPU by optimizing its power and temperature limits, resulting in significant performance gains. SoC voltage to 1. 3: 1/1: 10: Enable PBO, limit PPT in the range of 115-125, leave EDC and TDC set to auto. 51 You could set pbo limits to 1000 for every limit on high end motherboards, but no processor in the world is capable of pulling that much power, obviously. 6 GHz OC I never reach above 125. Load up BIOS defaults, go into PBO menu and enable advanced. 15V. On my motherboard, enabling PBO hides all power and frequency options, leading me to assume that 'enabled' would "Do what makes the experience better" - in regards to PCs and Life itself. But after booting into windows, the numbers are capped to the motherboard limits (e. . zanatos. Enabling PBO can raise those values to the maximum supported by the motherboard BIOS. Thermals are WAY better. If you are not hitting 100% of the power limits, raising them by bios or Ryzen Master isn't going to affect performance at all. You can also use Precision Boost Override Scalar Ctrl to increase the maximum boost voltage on the CPU. I simply enabled PBO. 06), 128GB Micron DDR4-3200 ECC UDIMM (18ASF4G72AZ-3G2F1) which opens in windows and applies PBO power limits and CO in real time. In order to get that Even though its an older generation EDC limitation might benefit boosts as the default PBO value is 160, which is too high even on a manual 4. 8) and an old one (1. after you set scalar to 10x then you want to Operating System & Version: WINDOWS 10 PRO GPU Drivers: GEFORCE GAME READY DRIVER - WHQL Driver Version: 457. ffudeh tttdm dvkh afli qsiml obqr frflgyz alsle skaesd sdo
