My values are the following: PPT 185 TDC 125 EDC 170 Max Boost +200 MHz (max I could input) Thermal Throttle Limit 255 Curve Optimizer -20 all cores Scalar ×10 Just scored 23,567mc -10 all core CO on the Ryzen 9 5900x never went past 69c during the 30-minute throttle test in Cinebench r23 no undervolting no extra mhz found my PBO2 limits scaler on auto posted it on Reddit Nervous King no undervolting scaler left on auto no extra mhz. As for the power profiles, you shouldn't really be running anything other than the balanced preset for Windows, it will adjust itself. Running PBO and the Curve Optimized is highly recommended. 25kH/S at 141W CPU Package Power Ryzen 5000 required EDC, TDC, and PPT tuning in conjunction with Curve Optimizer in order to get the best performance and reduce temps at the same time. But so far my settings are: core 0 -30 core 1* -35 core 2 -30 core 3** -30 core 4 -30 core 5-30 yesterday i installed ryzen 5600x, im using PBO2+curve optimizer with -30 negative and +200 to max boost, while im playing all games its okay, but in cyberpunk my cpu usage reaches 100% and cpu temp sits in 75-78*C, in other cpu intensive games i have around 65-72*C, is it okay or i should manually overclock to a fixed voltage and fixed frequency to reduce temp to stable PBO Curve Optimizer, Higher negative is better? PBO Curve Optimizer, Higher negative is better? By KhaderKh July 9, 2021 in CPUs, Motherboards, and Memory. Onyx: A MD Ryzen 7 7800x3d / ASRock Taichi 7900xtx OC / Gigabyte B650 AORUS Pro AX / G.

If there is a 5-10% gain in 1% and 0. 95GHz much more frequently. 80 under load with my GPU at 50 under full load. Skill Trident Z @ 3600C14 1. the 5000 series boost algorithms favour lower temps, so lower temp can equal higher boost freq, at the very least higher sustained boost. 43V not sure if it's still in safe range? The Curve Optimizer tool available in PBO2 is very, very good. Ryzen runs hot regardless, get a good cooler if you're really worried about temp. 45v (up to 1. Recently, The stock 5900X has only 142W power limit and 95A amperage limit which imo is way too conservative. In order to achieve an actual “overclock” on Ryzen 5000, we’ll need to dive into three major components – PBO2, Curve Optimizer and Power Settings On my previous chip, a 5900X, I could use these to find Machine Check Errors (mce) which are what Linux calls WHEA errors (Windows term) using the OpenWRT work load. PBO2 Curve Optimizer . I experienced around 10º decrease on idle temps (~50º), but still wanted to push it further to levels I'm used to when just browsing around and not playing or doing heavy tasks. 1% lows, then the "experience gap" between the 5800x3D What are PBO2, Curve Optimization, and Boost Override? Precision Boost Overdrive 2 (PBO2) is an advanced overclocking feature from AMD for Ryzen processors that lets I thought, it can be faulty core. This guide can be used I have my 5900X at 5. Temps are fine, 73-4 under C23 run on Arctic Liquid Freezer 420. Since I've got my 5900x I've noticed the voltage runs at around 1. But that system wasn't stable frequent blue screens and random restarts on a daily basis - usually when having lots of different programs running simultaneously - the Epic Games Launcher store is a *very* reliable stress test - lots of crashes here - still after their "AMD fix". Backed off on the CO settings and it fixed the problem immediately. g. 346 sec vs 54.

Now, for the most important part: The Hands down, I think this might be the best PBO2 / Curve Optimizer Guide to date! Just a small heads up: the current OCCT Beta can also show CPU errors per core, so you dont Really great temps and decent scores but had an outstanding question: is it better to use the offset CPU voltage or better to leave that auto and focus only on curve Optimizer offsets? Without the CPU voltage offset, I could take get my CO nearly to as good of negative curves and the heat was much higher, too. Discussion Always disable c-states when using pbo2 Reply reply The curve optimizer may not give you the best results for temperatures, but it can increase a bit the clocks, even at high temperatures. 1.
