Undervolting with optimistic PBO will get you higher game clocks and performance than all core or BCLK overclocks. Temperatures are up to 81°C And 95W package power. I tried 2x, 3x, 4x and I saw a jump to 88W but I am not sure if that is a A community dedicated toward all things AMD mobile. I got a 7800x3d with Asrock x670E and DDR5 6000 CL30, and I'm trying to enable PBO on it but can't seem to get anything out of it Cinebench score is the exact same with PBO - Disabled / PBO - Enabled / PBO - Advanced with 200+ and offset -30, -30, -6, -14, -19, -26, -16, -23 and temperature is around 63C with all of the settings with voltage A reddit user was saying that he tuned his 2 best cores for -24 and the rest of his system to -28 (I don't remember the exact values but that's not the point). PBO doesn't work. CPU soc auto to 1. Here is a quick look at the new 65W Ryzen 7700 performance gain with different PBO settings. We see all the "high end chips" needing more power, more cooling and yet here is a chip priced in the mid range that is running as fast or FASTER while sipping juice and running cooler than a Jamaican Bobsled Team. And custom water to keep temps down. Idle temp of 43C and gaming temp of 65C - 70C. Hitting 80 C when Idle and when putting it underload in Cinebench goes up to 90+. Some can do eclock generator which can essentially force an overclock onto it but it can break the CPU. Manual OC is apparently too dangerous due to static voltages. 494 volts peak. I bought a 7800x3d, and so far I really enjoy it. It seems for the 7800X3D you're already towards the top of the curve. 7800X3D PBO overclock Hi guys, just today I received my B650 Aorus Elite AX, 7800x3d and 32gb 6000mhz cl30 ram. x) AMD Ryzen 5 5600G with Radeon Vega 7 Graphics Maybe this info is not longer relevant, but I got the exact same issue in my strix b650e board. Enable PBO (I haven't touched other PBO settings) Set the curve to negative 20 Is this normal behaviour for the CPU? Shouldn't it stay at ~5. I could run various loads and then watch the clocks as I worked up and down on values to see the difference even trivial things like scalar made. I also want to further optimize the CPU if someone can guide me. Now, my best cores, according to Ryzen Master, appear to be core 02 as best and core 04 as second best. On my rig I find very little difference between the scalar settings - maybe 1 to 2C at max. You need to use a benchmark (Cinebench or other) while looking at the temperature. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC… Scalar at 2x-10x I see 1.

Most boards can do pbo offsets which should get some improved performance. Normally, Ryzen CPUs firmware manages the frequency based on the thermals and voltage and it will reduce your frequency if it sees either of those two going into ranges that reduce the long term reliability of the part. Get the Reddit app Scan this QR code to download the app now The Ryzen 9 7800X3D will kill the Ryzen 7 they probably add more improvement too going to be so good Undervolting using PBO will allow your CPU to boost near to max clock speeds using less voltage (heat). When I set PBO Advanced with +200 Boost (and some - offset which i found to be stable), along with PBO limits, I can't get it to boost stable, clocks are all over the place. All this effectively runs the cpu extremely cool while running at 5. 1 volt under full load. 2, SOC voltage 1. If you set your PBO Limits to "Manual" instead of "Auto" or "Motherboard" you can manually type in new limits for PPT/TDC/EDC. Don't know where you're pulling the 105W power draw nonsense from, but it's exactly that, nonsense. 7 Been rock solid with my 7800x3d / 6000mhz ram cl30 / PBO -30 on my strix x670e-e board. skill flare 6000mhz 30cl CPU 7800x3D It's a new build and I've applied a generous… Tried using Ryzen master a year ago or so, but couldn’t get the oc settings to run on startup so just went and used pbo instead in bios Reply reply More replies   1. I have researched PBO to make sure I understand how it works, however I have no clue what PBO Scalar is. The 7800X3D is nothing short of amazing on every level. This means that the limited amount of voltage available to the 7800X3D is maximised and the voltage won't droop under load. any For PCs that are too small for r/PCMR and the full tower subs, but too big for r/sffpc, welcome to micro form factor PC gang. AMD was clearly aware of this, and decided to withhold the 7800x3d simply to push an inferior product at a higher price. That's stock behavior. The one with aio gets 18k+ other one gets only 16k. ” The Granite Ridge processors were introduced on June 2, 2024, during Computex 2024. You could try to undervolt the CPU in BIOS, which will help with the temps. Restored default settings (f7) and reapplied only expo, 5050 boost was back. My suggestions for a "quick and dirty" 7800X3D undervolt (one that is reasonably stable for most people that doesn't take several days of effort) are to do the following: Boot into BIOS and set your CPU SOC to 1. Get the Reddit app Scan this QR code to download the app now 7800X3D PBO offset Help (General) HUB - AMD Ryzen 7 7800X3D vs. PBO "off" means 142W peak socket power. 🤷🏻‍♂️ Its possible and withou crazy values or cooling. Vermeer will try to boost as high as possible within the limits you are setting, where CO has slightly altered the VF curve for the cores. The CPU gives sensor data separate from the mobo, in the CPU section you'll see the low temp and the tdie temp and the mobo has the same values but with different names, for my 7800x3d and Asus board the mobo gives "CPU package" and "CPU", package is the same as tdie but the mobo gives only 2 digits like 89c, then under the Key Data Points: - CPU Thermal Limit: 89C - Curve Optimizers: PBO negative offset (measured in 'an order of magnitude') - Load Line Calibration (LLC): 8 settings (Auto, Normal, Standard, Low, Medium, High, Turbo, Extreme) - Settings Changed Per Test: Only LLC and PBO curve for each core - Indicators: Failed tests are marked in the notes and the Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. however I did just buy a whole system, 7800x3d + 7900xtx and giving my old 7700x+6900xt to my brother. I was talking with someone yesterday who found that going from 1x scalar to 4x scalar jumped his temps by nealry 10c at load. PBO helps more in single threaded apps (games) than it does in Cinebench. For our testing, we're using the same basic setup as our Ryzen 7950X3D review. 04, Chipset VDDG 1. I wish they made one for Ryzen 7000 series as now I have a 7800x3d, but man it really took a lot of the geusswork and time out of finding where my 5900x ran the best. In my case that is "39". true. 0375, SoC LLC mode 1. When scalar is not safe is when using the EDC bug, which already boosts voltage, scalar just makes it worse. I dont really know the specifics to OC this thing, but I enabled PBO (just a single option to "enable"), and set curve optimizer to "pbo, 85c, -30). Even the Stock PB factory settings try to eak out every little bit out of the CPU as it can and PBO streches this even further. I flashed the latest bios firmware for my motherboard and set the PBO enhancement to 90c - level 3, then I started stressing with Prime95. BCLK OC and stabilized settings: Bclk 105. 6C Cinebench multi I do 2 runs back to back, PBO without offset voltage really isnt worth the extra power and heat. I was at -15 and after benching a bit lower and a bit higher I was satisfied, temps were good, voltages were good, performance was good. Funnily enough, I checked Ryzen master if the PBO is successfully registered, on one screen it shows the requested -30 but on another screen, it shows -50, with 0 offset. PBO Limits Disabled PBO Max Freq +200Mhz Curve Optimiser -15 This configuration is stable but CO -20 becomes unstable. I have heard that it is for changing what voltages go to the CPU, but if thats the case then why do people use a voltage offset instead of just finding the lowest stable PBO Scalar setting? Here are my PBO settings: Core 0 -30 Core 1 -15 (My fastest core based on ryzen master) Core 2 -30 Core 3 -30 Core 4 -30 Core 5 -20 (My 2nd fast core) Core 6 -30 Core 7 -30 For frequency ccd, I didn't do anything to it. 4 volts, often clo After some testing on how AMD's PBO feature works, I found out that if you Set “Precision Boost Overdrive Scalar” to manual at 10x, the CPU voltage gets dangerously high with only a CPU test “System Stability Test” in AIDA64. With offset actually performs better on the second run and keeps temps reasonable compared to stock. Under "Curve Optimizer" change the sign to "Negative" and then you should apply as high a number as is stable.

This allows the cores to run cooler with less power input, which ironically gives them more thermal headroom to boost higher with lower temps. But that thing takes almost 200 Watts at full tilt. 05 at stress tests? Spec are: Ryzen 7800x3d 2*16gb G. The cooler was a hyper 212 black edition. At 1-core loads, you can expect voltages north of 1. In my experience setting pbo values to extreme high values does result in weird behaviour. I am using PBO CO -30 and everything else regarding PBO is set on Auto. The CO value on C02 is -30 but C04 was one of my failed workers, hence I set it to However I had some settings copied from a YouTube video for the 7800X3D stating that I should set it with the following values: Precision Boost Overdrive - Advanced PBO Limits - Motherboard PBO Scalar Ctrl - Manual PBO Scalar - 10x CPU Boost Clock Override - Disabled Platform Thermal Throttle Ctrl - Manual LLC mode 2, EDC 70, PPT+TDC 4096, Auto PBO overclock auto (basically 0), temp limit 70, CPU switching frequency 1000, over-under current both 400.
