7950x3d pbo scalar 105 eCLK -100 fmax PBO Enhanced Level 1 90c, scalar x6, LLC 8, no CO and it was almost fully stable boosting up to 5197 but again SHA3 killed it. PBO is a feature to help you overclock the cpu by removing power and current limits, increasing boost frequencies by maintaining higher vcore for longer with scalar. Even if you set PBO Boost Override to 200MHz the boost will be 25-50MHz at most, and only on certain cores. If I try using the high eCLK with -Mhz boost override it performa way better and I can even get it to hold 5200 in R23 with huge scores but it gets a LOT of random reboots. What I recommend is to look at voltage during ST and MT tests. Even increasing the PBO scalar didn’t help. 25了 Apr 16, 2023 · Ryzen 7 7800X3D PBO/UV: Corsair H115i 280mm water cooler, Precision Boost Overdrive (Advanced/Motherboard), Scalar 10X, -10 Curve Optimizer, DDR5-6000 EXPO Ryzen 9 7950X3D, 7900X3D, 7950X Oct 7, 2022 · Our updated PBO Enhancement BIOS feature makes it easy to limit the temperatures you’ll see with your new Ryzen CPU in heavily threaded workloads.

Nov 6, 2024 · Next, I focused on tweaking AMD Precision Boost Overdrive (PBO): I removed all the power and current limits (which aren't an issue anyway) I also set +200 MHz with a scalar of x10; Last but not least, I set Curve Optimizer to -10 all cores; That turned out to be fully stable, so I set -15, -20 and -25 with quick stability testing at each setting Mar 23, 2024 · CPU: AMD Ryzen 9 7950X3D PBO + Undervolt | MOBO: MSI MEG X670E ACE | RAM: 4x16GB @ 6000mt/s C30 | GPU: RTX4090 MSI Suprim X @ 3GHz | MONITOR: Acer Predator X32FP | PSU: Corsair HX1200i 1200W fully digital | UPS: Cyberpower PR1500ELCD 1350W | RADIATORS: 2x Corsair XR5 360mmx30mm | 1x Corsair XR7 360mmx55mm | FAN: 10x Corsair QX120 fans | PUMP: Corsair XD5 Elite LCD | CPU WB: Corsair XC7 Elite But if PBO is disabled - the setting works and then single core loads go to faster cores instead. 3V降到1. With PBO enabled and despite not hitting any of the ‘traditional’ limits (temperature, PPT, TDC or EDC) the CPU will not draw more than ~120W, or about 150W total for the whole package, SoC included. Temps aren't an issue. Boost clocks are the same and running pretty much 5. All Core offset of -35 and a temperature limit of 70 and I get pretty much the same scores as stock speeds. THERMTRIP on these parts is ~125C and those CPUs that failed spontaneously and catastrophically had to get to hundreds of C internally to do it. You can try adjusting the PBO voltage scalar setting, as that might let you boost higher but verify uplift, as this also increases heat. Conversely, frequency cores are far more sensitive to PBO offsets. I just used Ryzen Master to activate PBO (no manual changes) and curve optimizer set to -20 all core. However I am not able to get boost speeds constantly at 5. 摸索pbo2有段时间了，由于最近cpu和主板选择换了好几次，搞设置搞得都快成肌肉记忆了。结合一些网上的教程和实际使用说说我对pbo2 pbo scalar这项参数的理解。 Aug 20, 2016 · 求助 7950x3d bios应该怎么设置 在技嘉的bios里已经开启了expo， 还有一个pbo怎么设置 下面有很多选项不太懂 有同是7950x3d的人给个参考吗 7950x3d bios 怎么设置 20 50 Jun 12, 2021 · Since your results differ this seems to be a setting that is best left untouched, use PBO Scalar instead. I did some PBO offset to my 7950x3d previously, the specs are in the picture. Recently, I was using Corecycler + y-cruncher to do a per-core test every night for 30 min each core (a total of 8 hrs). 昨天闲来无事，想试试开了pbo2能提升多少，于是全核负压20，关闭节能，soc电压从auto给的1. 2v rock stable for many years, temp never above 50C i recently bought a 6800XT and im facing cpu bottleneck so im planning now to use PBO. This brings some secondary effects, such as more generated heat, both in the CPU and the VRM (due to current and higher voltage) and more temperature on the CPU. The temperature results remain very consistent. PBO Enhancement其实就是温度墙+负压，比如90 Level 1就是90℃温度墙，大概curve是全核-10的样子(-0. 290 vSOC, 6600C28 1:1 2200 FCLK, 1. Power is 130 watts vs 180 watts. This means it will keep the voltages during PBO higher for longer, multiplying the default length of time anywhere from 2x to 10x. I’ve mounted and remounted both CPUs 5X each. In addition to the regular performance, we were particularly interested in what is still possible with the new 7950X3D. . Jul 4, 2023 · You can only increase it by using less droopy LLC settings and by elevating PBO scalar (which probably won't amount to anything without scalping the CPU and DDing it) S3Trio 64V+/S3 Trio3D 2x/Radeon VE 32 Mb/Sapphire R9600/Powercolor 9800 128 bit/Radeon X800/M56/Toxic R6950@70 -> R9 290+Arctic ExtIV @ 1170 / 1500 -> Vega56 Nitro+ 1680/1080 Jul 29, 2023 · Precision Boost OVERDRIVE is what AMD is calling it when those three thresholds are bumped up.

To do it, on my hardware, I just have to manually set PBO scalar to 1x instead of keeping it on Auto, this somehow improves stability enough to keep the CCD1 at -10 and still pass it. These are the stock speeds. CPU : 13900K | Motherboard : Gigabyte Z790 Aero G | GPU : 2070 Super | RAM : DDR5 Patriot 6000-36 at 5600 CR1T | Hard Drive : Adata SX8200 Pro I have the same setup as you crosshair x670e extreme and 7950x3d just using a GeForce rtx 3090ti. May 15, 2024 · 7800X3D - PBO -30 all cores, 4. I did try setting PBO limits manually to “Motherboard” This caused my system to become unstable. PBO can help the CPU boost slightly higher, or consume less power, and therefore generate less heat, allowing the CPU to boost a bit more. This is with the CPU reaching a temp of about 56-60c during the test. I'm using 7950x3d, ddr6000 expo 30-38-38-96 32GB memory and on a 4090. 10 08:49.

I also tuned Curve Optimizer carefully per core, ranging from -18 to -2. I do have a boost override of +50 thought. I play most mw2. Is it worth running scalar? Scalar is good if you limit PPT, with high scalar x10 I could hit 4. Setting it to 10x worked well for our overclock. the reason the voltage is capped is because the 5800x3d has its voltage capped for its 3d cache. The power limit of the X3D will top out at around 165W or thereabouts regardless of how high the board allows you to set it. With -20 CO all core and scalar 6 it had the best score I ever had on stock clocks (19062) but it still isn't hitting full 5050Mhz. I guess the scalar could be considered "part of" PBO, but here you're decreasing power and temperature. However, I am finding that my system all stock settings (No Expo, No PBO/CO) seems to throw errors with this specific test even if others pass without any obvious issues for 30+mins. it's amazing how fast SHA3 can trigger a reboot lol. I initially set the curve optimizer at -30 for all cores, and I had instability issues by increasing the frequency to +200, so I had to lower the CO setting to Aug 14, 2024 · Ryzen 9 9900X PBO: Precision Boost Overdrive (PBO) — advanced motherboard, 10X scalar, +200 MHz CPU clock, -20 Curve Optimizer, DDR5-6000 EXPO profile (fabric 2000 MHz, mclk/uclk 1:1) AMD Ryzen Jan 15, 2010 · I was so close. the use of AMD’s PBO 2 and EXPO, the use of Nov 29, 2024 · Set PBO scalar. 25 for Mar 21, 2024 · If you enable PBO on a X3D dual CCD 7000 part, only the curve optimiser function of PBO will apply to the cache CCD. if EDC is over 140.
