They also say it's easy to cool on air and works beautifully, especially in games. this is an undervolting guide I wrote that was worth a ~5-6% boost in CPU scores. Because for me its to hot to run it in stock. 5. After bios reset i set -10 for negative curve and temps going down and boost is almost 200Mhz up My first couple of attemps with the curve optimizer in the PBO settings on the Aorus Master X570 ended with reboots and WHEAs But did some more tinkering Menu. I'm trying to set PBO + curve optimizer and coming from a 5900x and reading a lot of guides, it looks like best cores should not be Pbo curve settings in the negative reduce the power draw that each core can receive when they demand power. Buy AMD Ryzen 7 7800X3D 8-Core, 16-Thread Desktop Processor: CPU Processors - Amazon. Nobli85 • Done on a Gigabyte B650M Aorus Elite AX, a cheap ID COOLING Dashflow 240mm AIO, took a lot of messing with DRAM, SOC, and curve optimizer voltage to get it stable but now it is.

CO enabled (-30 all cores): 18190 Curve Optimizer is a great way to squeeze a little extra performance out of your 5000 series CPU, but it does take some patience to master!AMD recently relea We explained the difference between Core Frequency and Effective Clock in a previous AMD Ryzen overclocking guide. Hier konnte ich mich derzeit auch pauschal auf -25 All Core vortasten, was auch über einige Stunden Y-Cuncher stabil lief. The mathematical function f(x) = y where X is voltage and Y is clock gives a curve and if you apply CO - 30 it means you are moving the graph along the OX axis to the left. AMD RYZEN 7 7800X3D OVERCLOCK CURVE OPTIMIZER PBO EASY TUTORIAL FREE PERFORMANCE GUARANTEED 🔥 Also Here are the steps you have to take to optimally configure your 7800X3D. Share Sort by: It takes way longer even with my 7800x3D since you need enough repetition to make it worth and you need basicly twice the time with twice the cores. You’ll only have to follow the guide until step 5, the other steps are optional. just download PBO Curve Optimizer from GitHub here a guide with the links. **Do not breach past -20mv, 7800X3D does not like going past -20mv. There is the short and lazy way, which involves simply enabling PBO and setting a -30 all core offset under Curve Optimizer and just going about your business / gaming. I’m making this post in hopes that it will help other 7800X3D owners (current and prospective). There's enough guides on YT for this. yeah i have currently all this settings OFF. For a given voltage it will have a certain frequency. To access this feature, you must first enable the Precision Boost Overdrive (PBO) This video shows how to get free performance out of the new Ryzen x3d or v-cache CPUs. My sugesstion, start clean first, reset CMOS and try curve optimizer, then when its stable enough, go after SoC voltage and others. 2GHz. 4! The boost also went up from 5. Overclocking & CPU Frequencies.

This article deals exclusively with special benchmarks for the AMD Ryzen 9 7950X3D. I ran it at stock powerlimits with AGESA 1. ), then select something like "all cores", and then select "negative" and set it to -20 at first. FunkZ. I tried a quick and dirty all-core -18 and I noticed some instability (mainly in Hogwarts Legacy but also in Genshin) so I decided to try and use Ryzen Master and its auto curve optimizer. New posts. Curve Optimizer The more well known feature is Curve Optimizer, which you can use to lower the voltage targets across the frequency-voltage curve. Meaning, any give time the CPU requests X voltage, the board will take 0. > CPU: AMD Ryzen 7 7800X3D (SP 95) : // eCLK Mode : "Asynchronous mode" // BCLK2 Frequency = 104. my ram is a bit better, 6200mhz, 380 trfc, 36 on secondaries, 20 tfaw, 66032 97205 65739 read/write/copy, 58. My mobo is x670e aorus master. Basically, a 50mV undervolt tells a CPU that instead of operating at, say, 2GHz at 1V, operate at 2GHz at 0. Case: Pure Base 500 FX . 85 effective clocks in HWInfo. I tried it, just to get a rough idea of what negative offset values to aim for. As I remember, it works with a curve Here are the steps you have to take to optimally configure your 7800X3D. 7900x3d btw. Put SoC voltage to 1. Definitely runs cooler then before. 3Ghz when hitting the max 50. You'll see a left rail with menu items. Chose to test per-core and after a hour of testing it came back with a -30 on all six cores.

I only used PBO motherboard powerlimits, and the curve optimizer + 104 bclk Good luck tuning its a very hard CPU to fully understand. I'd recommend you to enable Performance Boost Overdrive in the BIOS and also enable the Curve Optimizer. The 7800X3D's extremely limited headroom is a fair bit quicker. AGESA and powerlimits will shift your curve for sure. Pros: Fantastic gaming CPU: 7800X3D RAM: DDR 6000 30/38/38/96 Settings: Memory: EXPO enabled voltage bumped to 1. All forum topics; Going off the guide there should be a button to Start Optimizing, but it's not there. In Windows, open Ryzen Master's "advanced" tab, look under the Curve Optimizer settings, and confirm that you see the "All Core -25" offset Both "manual" and "advanced" will unlock the Curve Optimizer menu ( do not select GPU Optimizer ! ). 95GHz, but then had to drop it to 5. You can also undervolt by lowering the operating temperature. 8 GHZ . But there are softwares you can run in Windows like PBO2 Tuner which will apply the undervolt values correctly, and there is a way to configure it to auto-apply at startup (takes a little research and effort but it's possible) Ryzen Master Auto Curve Optimizer settings are very optimistic and way over shoots what is actually stable. I was getting great benchmarking results but the system would crash to a grinding halt whilst in game. 35V was a bit high . AMD ZEN 3 PBO & CURVE OPTIMIZER OVERCLOCKING GUIDE. It compensates the voltage drops when starting a heavy task, so the cpu is more stable. Boost clock offset nothing happens. I set -25 negative curve for every core and +200Mhz positive boost and no difference. 6. 7zp. I finally set on 75W, still using the -30 negative curve optimizer and +150 MHz positive PBO clock. Each step is around 3-5mV. This is a beginner's guide updated with the latest techniques. I wouldn't go over 104 and idt you'll even get that without a frequency cap and like +20 or something on curve. Upgraded to a 5800x3D, used Curve Optimizer in BIOS for the first time, performance improved tremendously with much lower temps, total win-win. For example, on the 7000X3D CPUs the maximum allowed I'm having trouble Curve Optimizer feature in Ryzen Master. I got some nice results with a -30 allcore CO. After that, I thought maybe I effed up something in the BIOS settings, so I reset everything and just enabled my EXPO profile. You have to select either All Cores or Per Core first, then Apply. I don't understand how this curve works on CCD0 with cache. Built a couple of PCs before, but this is my first ever personal build. Got a 7800X3D two weeks ago and I was terribly disappointed with the idle temperature performance. If not, you have to download the program and do it that way. Maybe it's geared towards AGESA 1. -30 all cores, 125 PPT, 80 TDC, 115 EDC Is there a good guide for that you recommend? I’m just using stock 3200 CL16 What sort of clock speeds were you seeing stock? I started messing around in curve optimizer because my 7800x3d doesn't seem to really be boosting single core at all above multi core, and by default was doing like 4.
