Does curve optimizer lower temps
Does curve optimizer lower temps. My scores are now back to 37K. It only benefits extreme Short burst scenarios (like under 3/4 secs). -30 all cores, 125 PPT, 80 TDC, 115 EDC I currently have PBO enabled and curve optimizer set to negative 7 which tested stable. Power consumption always appears to be 65w. Oh and all this was Air Cooled with a Noctua NH-u14S, in push/pull configuration, in a Fractal Design Meshify C with 4 140mm fans (2 top and 2 front), and a 120mm exhaust fan. 6%) and the MT performance is very similar, perhaps slightly higher. Went after Curve Optimizer, Scalar and added again more negative offset. You can go lower for less voltage but you risk instability. Because the limits don't change but your CPU can stretch it's legs better. It aims to lower voltage without sacrificing stability, resulting in potentially lower temperatures and potential performance gains. But I can see in HWInfo that the CCD1 and CCD2 are far away from these temps during gaming and cinebench. And my performance has increased. Finally, the EXPO (But I would do this before Curve How to undervolt AMD 5000 and 7000 series Desktop CPUs with curve optimizer per core. and regarding this thread it seems to be pretty normal for these CPUs What Curve Optimiser lets us do is tune this curve ourselves so that even the crappiest CPU can take advantage of lower operating voltages and temperatures while increasing performance. The idle voltage is lower (now 0. Vcore offset moves the entire curve up / down. Curve Optimizer is Curve Optimizer is basically a way of overclocking by letting the PBO algorithm know that your CPU isn't actually as shit as it initially thought. TLDR. 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 Feb 27, 2023 · 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 -15, where everything went fine. - You would say: "but that is stock, you did nothing!" Oh, but I did. Im running my 7950X3D with Curve Optimizer Negative -25 and I am still hitting the 89°C on package. 94 V from 1. Jan 30, 2021 · How To Squeeze Every Bit Of Performance Out Of An AMD Ryzen 5000 Series Processor. However, my CinebenchR23 scores significantly improved from 13714 to 15293. As 125W + Curve Optimzer -30 applied, the Cinebench nT performance is close to stock Ryzen 7900X. For example, my 2 best cores are at -28 while the others are at -30. It's really quite easy. Jul 9, 2022 · I found that using a negative offset on top of Curve Optimizer did result in lower temps overall and higher clocks under load in CB test, but I did not spend the time to stabilize it and ended up getting random restarts at idle with -. Lowering the curve optimizer is not overclocking it’s undervolting…and the reason for this is to lower temps/energy consumption by maintaining a good as possible clock. This video will show you the simple steps with Ryzen Master to test you Aug 5, 2021 · Curve optimizer, in and of itself doesn't alter voltage, it alters the boost frequencies at a given voltage. Mar 24, 2021 · Temperature: 75. Preliminaries 2) Enable PBO2 then on the curve optimizer do something like a negative adjustment and select 30 If you don't experience any crashes/instability that's it, otherwise you'll need to keep decreasing the adjustment to 25, 20, etc. It won't persist across reboots but your temps should drop considerably. The performance increase was nice, but the temperatures went from 62°C (the maximum temperature during stress testing) to 85°C. I have not touched any other setting otherwise, I can see in Ryzen Master that core voltage goes as high as 1. Do plenty of stress tests to ensure a crash free system. Curve Optimiser is overclocking. First let me talk about Undervolt and Curve Optimizer. In the Curve Optimizer menu, set your two best cores (HWinfo perf 1/1 + 1/2) to negative 5 and boot into windows. When a core is under load, it gives it extra voltage. This allows the cores to run cooler with less power input, which ironically gives them more thermal headroom to boost higher with lower temps. The negative curve will lower your voltage but increase your current draw due to the higher clocks, which means you'll be back at square one when it comes to power draw. The Geekbench ST score increased from 1635 to 1710 (4. Not an expert, but this is my understanding of it! Curve optimizer doesn't reduce the power/temps of the CPU, it just makes the CPU use a higher frequency for the same amount of voltage. By combining vcore offset and curve optimizer, you can really fine tune things like super low idle voltage (lower than -30 CO allows) and at the same time get enogh voltage for light and medium load. This is where the curve optimizer comes in, you Jan 21, 2024 · They replaced it with a new one. For this, load up PBO, Advanced, and go to Curve Optimiser. Temps are about 4 or 5 degrees higher with pbo disabled too under multi core load. So if you play a game that support multi thread, using the trick of curve optimizer negative values won't help at all. Overclocking a CPU used to be a pretty simple process: change a bus speed or a multiplier, set an appropriate Apr 13, 2021 · A user asks if undervolting and using Curve Optimizer to boost CPU performance will shorten the lifespan of the Ryzen 5900x. This helps a lot. When I used Curve Optimizer on the old one, power consumption was as low as 45w. (It crashed when set to 10 when running CineBench R23). You can also turn on ECO mode, which sets the power cap to 65w, or you can do the same thing in PBO by reducing the 4 limits. In Ryzen Master, do this by selecting Curve Optimizer in the profiles section on the left, then setting Control Mode to Default . I had already set -30 as negative offset for the curve optimizer, but this did nothing to power draw or temperatures (my previous Ryzen 5 7600 dropped from 90 watts to 78 watts and dropped 10 degrees). 1v, for example) or use curve optimizer to more adaptively undervolt on a per-core basis. Some people still prefer manual all core OC, and with that, manual negative vCore does the trick. At first, I let Ryzen Master handle it, and it worked well, setting all cores to -30. With my NR200 case and a Noctua NH-D12L, and the following : Stock : no Curve Optimizer, no PPT limit Custom : Curve Optimizer -35, PPT limit 60W Nov 5, 2020 · The much anticipated Zen 3 architecture has finally been launched close to a year and a half after Zen 2 while remaining on the same 7nm TSMC process. 3, no matter if I put the negative offset 5, 10, or 15. The CPU will downclock to maintain safe temps (below 90C). Is this likely due to what you said about clock stretching and requiring curve optimizer in the equation? I was surprised to see my scores and temps higher running essentially stock. Below you can find my findings on overclocking and performance tuning. You don't lower power consumption using Curve Optimizer, you increase performance at the same power. Why would a more conservative undervolt for the best core be better even for single core applications? It sounds like you're using PBO with motherboard limits which will just use more power when you lower the Curve Optimizer. You'll have to set a negative curve and lower your PPT. Undervolting gives a temperature advantage which PBO2 can use to automatically clock higher (my assumption). 0 V) and the idle temperature is about the same (30–31°C). I prefer to do individual core testing. stock vs stock and Curve optimizer vs curve optimizer with these limits results in the same gains. 45 and wonder if I should change something to reduce this in order to get lower temps. Curve Optimiser is NOT undervolting. I don't own your CPU model, but I do have a Ryzen 5800x which is quite similiar to yours. Abient temps were 22 Did a quick test on Ryzen 7900 with different PBO settings and Curve Optimizer and see how the performance scales and CPU temperature. The BEST answer is to use Curve Optimizer (more performance with lower heat). So, if I understood correctly "Eco Mode" is just a profile for the specific thermal and power targets for PBO. Jan 17, 2024 · Instead of overclocking your AMD CPU, the idea is to intelligently adjust the voltage-frequency curve of the processor to achieve the same performance at a lower voltage and temperature. 6⁰C. It will lower your performance but temperatures won't exceed it. May 5, 2023 · Started with the usual Offset undervolt which lowered temps, thus increasing a bit but not much. Lower your max boost offset thing (forgot the proper name) if it's at 200mhz. Apr 16, 2022 · AMD's Ryzen 5000 and Ryzen Threadripper Pro 5000WX CPUs will support this new curve optimizer. Just download the utility from the thread I linked, open it up, start with a -10 offset on every core and then apply. Dec 2, 2022 · I have a new build consisting of a 7950x, and x670 gigabyte aorus elite ax rev 1. Because it doesn't do whatever you seem to think it does. Normally people don't use vCore offset with Curve Optimizer, but I find it handy since I'm running a 240 AIO on a 7950X. 5° At this point, CTR starts to do its thing: measuring the cores for frequency, voltage, and temperature. If frequency is capped via something else, then yes, voltage will also go down, but if allowed, voltage will scale normally and boost speeds will increase with the larger negative offsets. 1 and 5. After so much reading about curve optimizer and undervolting, from my understanding i might be able to get the same or even better performance setting PBO with a negative offset in curve optimizer, while using less voltage on the CPU, and so, lower temps, which might increase the CPU's lifespam. Oct 28, 2023 · Sometimes, depending on conditions, curve optimizer can lead to a lower average temps but increase full load temps. Mine reboots if I push it past 125mhz while using curve optimizer. How to access Curve Optimizer feature in Ryzen Master? A dedicated profile is provided for this feature named as "Curve Optimizer"€ Is it supported on all AMD CPUs?

Default is 76, 60, 90. As you will see in the following graphs, the overall gaming performance is similar, while the applications’ overall performance gets a small boost Jun 25, 2021 · CO aka curve optimizer is a option to undervolt your CPU , the idea behind it is that your CPU will run cooler with less voltage but not all CPUs / cores are the same, some can work with lower values than others. Curve Optimizer in my understanding is just undervolting. Basically, a 50mV undervolt tells a CPU that instead of operating at, say, 2GHz at 1V, operate at 2GHz at 0. First, the testing environment and equipment: Legion 7 Gen 6, Repasted with PTM7950, with a Ryzen 9 5900HX Sep 3, 2024 · This screen shows you sections like Temperature, Speed, Power & Current for system monitoring, including Control Mode, Curve Optimizer, and Cores Section options for any existing overclock details Oct 4, 2023 · 3. AMD Power Curve Optimizer Results: 5 GHz+ Jun 25, 2021 · the curve optimizer is mentioned in mussels post. By manually using the curve optimizer (and power and thermal limit) we can fine tune those values to our particular silicon to potentially get better results than Eco Mode alone The AMD APU Tuning Utility team have recently released a build of AATU (found here) that allows the manipulation of the V/F curve for 5900HX CPUs, in a similar fashion to the desktop 5000-Series Curve Optimizer (0 to -30 max limit). 5 for the The issue is, as you lower it, the benchmark starts being impacted. If you want lower temperatures you need to set limits for PPT, TDC, and EDC in BIOS. Keep your two best cores with a lower negative offset than the others. Decided to replace all the case fans with x6 Noctua NF-A12x25, which helped, and lowered the idle temperature by 5º and the noise became acceptable. Considering CPU temparature and Cinebench R23 performance, it looks 105W/125W Config TDP is good for my system. If you just want a temperature cap then you need to set a temperature limit. That worked! However, CPU would run 88-90 degrees. With the scalar dialed back to 2X, temperatures topped out at 78 C and power consumption was around 115 W. . At idle or moderate load the voltage is lower - sometimes too low with aggressive curve optimizer negative offsets. I know my Cinebench R23 score is 15500 multi, and my single core is somewhere in low 1600 don't have that off hand right now. Anyway, testing… The boring part but the most crucial. Temperatures are at least 10 degrees better across the board; 40s and sometimes 50s in games, 60s at full load. This stabilizes the FPS and re Jun 10, 2021 · Since AMD doesn't really want to spent time finetuning each individual CPU they sell, they use a curve that is stable for every single one of the 5600X sold, but depending on your luck in the silicon lottery your 5600X (or at least some cores of your CPU) could be running stable at lower voltages. Mar 12, 2024 · AMD Ryzen 7 5700x3D Curve Optimizer or UndervoltingReducing Core Voltage reduces (Vcor) power consumption and CPU temperature. I was able to lower the temperature using Curve Optimizer with the old one. Anyways I also tried using the curve optimizer with a -30 voltage offset on all cores and it seems to be stable in benchmarks, however the temps are the same as stock under load, just the CPU is running faster, which makes sense given how curve optimizer works. Unlike idle and very low load states, however, there's no wild fluctuation in temperature since the chip isn't chugging voltage like it's bud light as the boost is disabled. PBO 2. This is all with similar (maybe very slightly higher) load voltages and temperatures. but with the new one, the temperature doesn't drop at all. I have tried in ryzen master, as well as the BIOS, during r23 multicore, it seems to pull between 220 and 230w according to Core Temp, and boost between 5. Hey, a few days ago, I learned about Curve Optimizer. AMD's recently released Ryzen 3000XT showed there are frequency gains to be had just by manufacturing improvements over time. I set my curve to -30 across the board and have lowered my temps from the thermal throttle at 89c all the time to the 50-70 range with no crashing or problems yet. Anecdotal evidence suggests that this DOES NOT WORK with 5800H/5600H. In my experience it actually makes the CPU draw more power. Even if I do negative -30. My cpu is on air, so I'm wondering if I'm already hitting the ceiling of performance due to temps with regards to curve optimizer vs defaults (actually had a lower cpu score in Timespy cpu score with curve optimizer and tweaking values on individual cores than I did at default settings HWINFO (to get the preferred core order and, optionally, compare before and after temps/power) Core Cycler (which contains PBO2Tuner – set and test curve optimizer values) CPU and gaming benchmarks (compare before and after performance, test for real-world stability) 2. With the recent release of AATU's Curve Optimizer offset tool, I decided to spend some time doing an analysis on the relationship between power draw, thermals, and performance, at some arbitrary curve optimizer offset steps. A way to counter this is to play with the Curve Optimizer (PBO2) in Ryzen, and go for the lowest, while not crashing of course. Dec 25, 2020 · If you want lower temps overall, you can undervolt (set vCore offset to -0. I do use it. It does this to get a handle on what the performance potential is of each core, as well as its power efficiency. Does curve optimizer alone only lower temps/power draw? Yeah but that can result in better performance. If your fans are too loud, turn them down in BIOS. Other users reply with explanations of power, current, voltage, and Ohm's law. That's where lowering your PPT comes in. I can get 37K with EcoMode 105 and a 240 Rad watercooler, its not a 360. Curve Optimiser doesn't magically lower temps. So in multi-core you can get better performance (from more consistently high frequency) and better temps (from lower voltage). Curve optimiser defines the shape of the voltage curve. Max temps we 78. In the event that this is already too much for your cpu, try lowering the values in CO or lower the boost override by 25 Mhz and try again. Yes it will definitely lower your performance and the key here is to sacrifice only x% performance while saving x% energy. That will require hours of testing. 85ghz is when I applied -30 on cores 1 & 2 and the rest on -5, with default power limitation, but the cpu frequency kept lowering based on the CO value, so why is that, and is that even normal! Apr 20, 2022 · The nature of how curve optimizer works means that you are more likely to have instability when your system is idle than at full load (even when testing only one core). Since I don't really like those temperatures, I went further and tried to reduce the power draw. Anything that will allow higher boost clocks will benefit performance to some extent, but there is also a hard limit on the clock speed for X3D cores that is implemented by a maximum allowed multiplier - 50. 95V instead, and whatever frequency is mapped to 1V is now >2GHz. The question is what else is brought to the table. Also it seems May 19, 2023 · To counter this, I have an negative vCore offset to lower things a notch, so temperatures will not reach near 80ºC but cores will boost like crazy for much more time. 0 w/ Curve Optimizer: Undervolting is a way of overclocking CPUs and GPUs that have an internal table that maps voltage to operating frequency. Tried everything and I couldn't find a decent fan curve that would be pleasant to my ears: an aggressive curve was way too much noise with the case next to me on the desk. but in my case even an unstable -20 across all cores makes a difference of 1-2 percent. The only exception will be the Ryzen 7 5800X3D which does not support core overclocking by AMD. You will see a number of things appear here, like the priority order of your cores as well as a boost tester. It will help for single thread load tho. A lower voltage directly translates to less power consumption, and therefor lower temperatures, which means higher boots clocks. If the CO does lower temperature overall, skip undervolt (since CO is already undervolting) then try -15, - 20 and so on till you find a sweet spot. Sep 8, 2024 · Curve Optimizer is a feature within AMD’s Ryzen Master software that fine-tunes the voltage curve of your Ryzen CPU. Jan 16, 2021 · I already saw a couple youtubers testing curve optimizer vs Max single Core like +200 and in most cases they ended up at +0 or +50 for the Overall best Performance since you can input lower – numbers in curve optimizer which means less heat. In gaming the temps are slightly better than stock (50-60C with CO, 55-65 without Jun 22, 2023 · There are several ways to do it, vCore Offset is more towards older Ryzens where curve optimizer wasn't a thing yet, although it can still be used today. Why is the core boost based on the Curve optimizer! cause for me I tried disabling CO and have +200 mhz core boost, but it didn't change anything, The one time I managed to get 4. Upgraded to a 5800x3D, used Curve Optimizer in BIOS for the first time, performance improved tremendously with much lower temps, total win-win. Smoother gaming performance too. Your BIOS may have a setting for max temperature under PBO, mine does just set a lower temperature there, such as 80C, and then use Curve Optimizer to eek back some performance, might even end up above stock. 0, using curve optimizer does not seem to be changing my power draw at all. With the PBO Scalar set to 10X, we saw 125 W of power consumed during an all-core Cinebench run with temperatures up over 82 degrees Celsius. Curve Optimiser shifts the voltage/frequency curve, setting a negative offset shifts the VF curve so that the core will boost higher at the same voltage. 1125v, although it did not throw any errors during testing. Dec 3, 2022 · The 5800X3D will not reach its peak frequency when in a multi-core load with the stock curve, but it can reach it or get much closer when undervolted.
