Benefits of undervolting cpu reddit. Let's talk modern CPU overclocking, if you want to talk overrated. Let me tell you why undervolting is such a great thing and why you should be doing it. 9v for 4. Run a few benchmarks with no undervolt and then do a few with the undervolt. In PCMark 10 we picked the Web-Browsing, Word Processing and Spreadsheet editing workloads. I have no idea what is causing the difference though. I've been harking on the benefits of tweaking an undervolting curve for the G14 for some time now and I finally managed to snag the time to put together some for it. Specs: HP - ENVY x360 2-in-1 15. Before we get on with the steps to undervolting a processor, it’s best that we first explain how it works and its benefits. The same principles applies where you need to balance the voltage and clock speed up against the cooling capacity and stability of the CPU. The main benefit of Undervolting is to reduce the cpu temperature thus decreasing the chance of throttling which reduces your cpu speed (performance) when it exceeds a certain temperature. I don't think you mentioned what GPU you have, but 85-90C is a typical throttle temp for GPUs, so ten bucks days your gpu is Undervolting is safe-ish; worst result is instability. I really want better performance and I think this is the only other way than to buy a new PC. The hardware is already so efficient that the final frontier is to go the opposite direction due to the greater benefits in heat and energy reduction compared to relatively small gains in any form of performance, games in particular, but I'll admit I don't know if video rendering software would be hurt tremendously by such Dear all, I am considering undervolting my laptop to improve battery life (both cpu and discreet gpu). So hit 15W cap with a slightly higher core clock as you'd expect with small undervolt. Undervolting seems like a bad thing. When asking a question or stating a problem, please add as much detail as possible. This undervolting stuff looks pretty beneficial and I understand it can boost performance, lower battery consumption, lower CPU/GPU load if I remember, and some other stuff. This definitely helps and is actually pretty sensible. They say it takes low power, so there's less stress on CPU and the temp stays down as a result. 6M subscribers in the Amd community. Undervolting When you undervolt you're removing headroom and giving Ryzen less power to use for it's boosting algorithm, there's no need to do it unless you want less performance. It actually does work, before without it the i5-9300h would only do 3. The one difference is if you allow the cpu to down clock at idle the more you undervolt the more chance you can run into idle stability issues from low voltage. Stress tests and benchmarks will also help you determine if the undervolt is stable. My undervolt settings on BIOS after short searching, CPU Cooler Tuning: Boxed Cooler (PL1: 253W) BCLK 100Mhz Lock on: Enabled CPU Loadline Calibration Control: Mode 5 CPU Core Voltage Mode: Adaptive Offset CPU Core Voltage Offset Mode: - CPU Core Voltage Offset: 0. 35GHz at 1. I was able to get -0. My moderate undervolt gives me better performance on every game I've tried. Because the CPU consumes less power, it takes longer to trigger higher fan speeds. If you drop voltages far enough you will get crashes. 9-4. 2. Now, with a massive undervolting, it finally got a chance. That's cool and all. We disabled Undervolting on laptops is mostly beneficial on the CPU. I have a Ryzen 5 3600 that runs kinda hot and I am thinking about undervolting since I've seen it doesn't affect performance in a noticeable way, specially if the CPU is new. Undervolting also has benefits during situations of light usage like web-browsing, video call and office mode. Some stability issues don't make themselves known immediately. 812 cpu MHz : 2879. Table of Contents show. , 4. Undervolting the CPU cores improves power efficiency but also limits how high you can push the core frequency. Simply just booting up the game would crash it. None of the boards from any vendors allow it to be changed in BIOS, it's locked out by the AGESA code from AMD for the 5800X3D specifically. TL;DR: I undervolted my cpu through PBO2, I got the same max clockspeed across all cores but got a lower score in Cinebench R23 So I found a video on youtube that claimed that undervolting my Ryzen 5600x would give me free performance and decrease my temps by 10-20 degrees Celsius. 0ghz with the temps at 85-90 sometimes 93 degrees with a max cpu power of 48 watts, with a cinebench r20 score going as far as 2007. The cpu gets fed more power than it needs as a default. The idea behind undervolting is to find the optimal minimum voltage that a processor can use without causing performance losses or instability. While it can't damage the CPU, GPU or other electronics, it maybe could damage an old hard drive if the PC suddenly turned off (if you even have one, basically all new HDDs have a protection mechanism for sudden power loss, so a When you undervolt your cpu or gpu, you're changing this relationship to obtain the same clock speeds at a lower voltage, so now with an undervolt the graph now looks like 0. 35GHz and motherboard automatically applying voltages but undervolted? It is IMPOSSIBLE to harm ANY component of your laptop via undervolting either the CPU or GPU. I installed Ryzen Master and AMD Adrenaline software already but still feeling a bit wary of changing the settings. Recently I saw that Ryzen owners are willing to undervolt their CPU to gain extra performance from Precision Boost Overdrive. Jul 6, 2022 · When you undervolt a CPU or GPU you're reducing that pressure, which has an effect on the energy available for that processor to work. Here is an Excel file with all the test results, baseline information and some notes. 2 days ago · Why Should You Undervolt Your CPU. 6" Touch-Screen Laptop Intel Evo Platform Intel Core i7-1255u RAM 16GB Memory 512GB SSD I want to undervolt the laptop so I could atleast lessen the usage of CPU temp and also game for atleast 70 °C to 80 °C without worrying of damaging my laptop than intended or getting up to 90 °C. 9GHz. Your GPU will only enter this state in low-load scenarios (like when in the game menu, or running older titles) and this is precisely the situation where you don't need higher clockspeeds. thus you can maintain higher clock speeds for longer. Undervolting lowers the voltage use given a certain frequency. Full stop. Just curious, have you tested your 7800x3D stock vs with your current CO on games exclusively? I see people testing/benching stock vs CO results though only in Cinebench/CPU-Z and such, I'm kinda curious to see if it affects gaming results in any way, be it higher effective clocks (and slightly higher performance), a bit lower power draw/voltage (therefore lower temperature) or something like there are many benefits to an undervolt especially for a laptop. 976 cpu MHz : 2878. 039 But I really don't understand this undervolting. Depending on your CPU you may be able to set a very small offset and have no tangible performance loss whilst lowering temperature by a few degrees. Q: What are the benefits and risks of undervolting a CPU? A: Benefits include lower heat and power consumption, and potentially longer Undervolting is a process which reduces the excess "voltage" given to the CPU using a software. 8GHz, and 1. I decided to undervolt my Ryzen 7 2700X by messing with the offset voltage. My voltage is now lowered and I'm gaining extra MHz from undervolting. I have 6800xt and I tried my hand at some undervolting. 05GHz improvment at the same power limit. you can use undervolting in combination with that - undervolting will reduce the power that the processor receives, lowering power consumption and heat generation - potentially with the drawback of crashes if you go too far. The main benefits of curve optimizer is the fact that the CPU will consume less power and draw less heat while boosting higher, just test the cores with OCCT or PRIME95 to check for instability, maybe even use the software first to have an easier time while testing. I undervolt both my CPU and GPU. All CPU's have different tolerances for undervolting, and it becomes a compromise between stability and performance. 1v for 4. If you want your CPU to run at those higher speeds, you often have to give it more power (more volts); otherwise it can be unstable. Optimum Tech was great to point out also that sometimes getting a higher binned chip is actually worth it for the better undervolting performance, which allows you to get the best out of a sff case. See full list on digitaltrends. 2GHz frequency improvement at 65W power limit, but undervolting with exactly the same voltage offset value in BIOS only gave me 0. Looking at guides online the writers all say its "generally safe" but don't specify any risks involved. e. . since it produces less heat also, you're giving more leeway to your gpu when using both. A lot of the time undervolting your cpu can reduce performance when it’s not needed. Yes, undervolting improves the overall lifespan of all laptops, improved thermals and less power draw both helps in extended battery life and health of components. Is undervolting more effective than manual setting a fixed voltage? For instance, would setting an overclock of 4. If you have a specific Keyboard/Mouse/AnyPart that is doing something strange, include the model number i. For reference, my GPU seldom got above ~60C even when my CPU was blowing past the thermal limit. g. you can probably find undervolting numbers that might work with your specific cpu, but silicon lottery plays a big role That's pretty high. But i feel like I'm not using my CPU at its full potential! I heard about Undervolting before. High voltage levels often result in elevated temperatures, which not only hamper performance but can also lead to long-term thermal damage. At that point you have a cooler running CPU which MAY then have some thermal headroom for overclocking (as the CPU runs cooler, the "boosting" in most modern CPU's has more headroom). It is like overclocking but instead of maximizing performance you are minimizing the power consumption and therefore the heat generation. The tradeoff is if you are too aggressive with the undervolt some games might crash. This is widely used as a cooling solution and in my opinion more effective than any other cooling solution available (thermal paste, cooling pad, etc) at NO cost. 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) Undervolting isn't guaranteed to work at all, and while typically works better on higher-end CPUs, like the i9, that's also not a guarantee. 5ghz). I undervolted and my Temps went from 95 degrees and the cpu thermal throttling to staying under 80 when playing cyberpunk. Would anyone who knows much about undervolting Start at -10 and work your way down. Most of your average desktop PCs operate within a temperature and boost range, so that undervolting doesn’t increase boost clocks. BTW Metro Exodus is a great testing game to see if you get any crashes. That will tell you if what you're doing is worsening the performance significantly. So essentially while undervolting my card is great for its benefits, given the amount of GPUs they have to sell if the deviation of cards having issues due to undervolting is another 1% not being stable, it's 1000's of gpus that are now unsellable. Doing so can DRAMATICALLY reduce the heat generated, and thus result in lower temperatures. Improved Performance: Undervolting lowers the GPU temperature, allowing it to sustain higher clock speeds for longer, resulting in faster and more stable performance during intensive tasks. Aug 26, 2023 · Benefits of GPU Undervolting: The benefits of GPU undervolting include: 1. is it worthwhile undervolting CPUs in terms of temps, or do the risks (BSoD) outweigh the heat benefits? do you undervolt your CPU? if so, which programs do you use? Note: I’m not interested in overclocking as I currently have the performance I need for my use case. The results illustrate well the benefits of each undervolting method. I suspect that's your issue - the cooler is struggling to handle the CPU and GPU at the same time. When undervolting, the worst that can happen is your CPU/GPU not getting enough power and turning off the computer. Of course it's possible to undervolt GPUs using MSI Afterburner's voltage curve and I've done it before, but there's always the chance Nvidia Optimus messes with it and either disables it or makes it unstable since it stops recognizing the GPU every time it turns off and switches to iGPU. What is Undervolting and Why Undervolt Your Laptop. In my humble opinion no amount of Undervolting or good repaste can fix over heating if your surroundings are hot and your gsme/software is cpu/gpu intensive. Apr 24, 2024 · Q: What is the process of undervolting a CPU? A: The process involves using software to incrementally lower the CPU’s voltage, monitoring for stability and performance to find the optimal voltage setting. I wanted to get this done sooner, but have been caught up with work (was working 2 contracts). What you're risking is stability. The benefits are lower Temps which increases longevityof your laptop. 45v be worst than having 4. Wild but makes so much sense. The benefits in overclocking the low-range are quite minimal. Yes, in that you won't damage your hardware. Or right after loading a saved game. I thought so too based on the name and the function. 1. 15 on my i7 13700k and playing The Witcher 3 was perfectly fine. What benefits does undervolting provide, how difficult is it to find good settings, and am I able to/is it worth undervolting and OCing my GPU? Edit: For anyone curious, I managed to undervolting to . ) Undervolting is a way to tune your CPU. This is exactly what happens to me. Due to how modern silicon works, if a CPU has more thermal headroom and effectively more power available, it will be able to boost higher and for longer. Even if you can't UV the CPU, having lower temps (And better performance) from the Gpu will help keep your CPU slightly cooler as well. as @dagrim1 mentions you're getting the same performance for less energy and heat. 095 Long Duration Power Limit: 125W Hi, there's a lot of advice online about the benefits of undervolting a Ryzen CPU and Radeon graphics card. 5 ghz with 100 degrees but so far with this configuration -160 core, and -170 cache it does 3. On my GS66 undervolting using TS gave me 0. disabling turbo is good too but undervolting is a seperate tweak altogether. 875V 1950MHz. Most every board from an AIB is clocked as high as it will stably run at its ra This definitely helps and is actually pretty sensible. Only thing happening is you get happy numbers in HWINFO64, but performance tanks. gra Howdy Ladies & Gents. Undervolting is when you program the computer to send less voltage to the cpu. As a result, you may see a lower voltage, an improvement on the CPU frequency, and a thermal throttling CPU. For PC questions/assistance. Undervolting the SOC is "free" power savings which the CPU cores can then use instead. That latter bit is pretty much where I'm especially standing on. 7GHz, 1. Changing the offset undervolt back to default stopped the crashes. You just have to test with the games you usually play. 100% of ALL gaming laptops should have both their CPU and GPU undervolted. Sep 11, 2023 · The primary benefit of undervolting is the reduction in CPU temperature. Jul 14, 2024 · I've tested 3 different undervolt configurations, all with CEP enabled, and have compared them with the default Lite Load 5 preset, with CEP disabled. Before undervolting, it can not reach the max frequency because it throttles. Overclocking = making the CPU run at a faster than stock speed (e. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen3, RDNA3, EPYC… Nvidia and AMD are tuning these cards within an inch of their lives from the factory, resulting in stock cards bouncing off power limits if not temp limits too. Dec 22, 2021 · Undervolting pros and cons It’s perfectly acceptable to leave your GPU at stock settings, and happily run it for eternity. You just don't see a performance difference until you drop the package power really low, below the ECO mode setting. CPUs use different amounts of power based on the task they are working on. Make sure to stress test just like you would for an overclock. So at the same performance you indeed use less power, and as a result you also generate less heat. However, manufacturers usually go a little further than necessary to ensure reliability on bad silicon lottery chips, so there's almost always a little room for undervolting with absolutely no downsides. Benefits to GPU Undervolt are enormous, so I'd definitely look into that. The following test was done in 'Balanced' mode. Compare the results. 976 cpu MHz : 2879. It's typically not worth the time and the effort (it takes hours to really get undervolting + stability dialed in) unless your CPU is actually throttling itself to stay within designed operating temperatures, and in your case I had an offset of -0. People out here undervolting 65w desktop CPUs thinking they’re achieving something lol. I have used throttlestop on my 7 years old laptop too, some options where hidden as it doesn’t turbo but undervolting cpu power draw option was still there and worked. I'd be curious to know what all-core clock the OLED can hit with the newer APU presuambly being more power efficient. Undervolting can be a good idea if you suspect the manufacturer overvolted a component or for benefits such as heat reduction, power saving, etc. Overclocking is safe-ish (provided you can cool the extra heat without issue), though it's largely pointless on modern cards. Power through work more efficiently and confidently with the help of Grammarly!

Undervolting can make performance more consistent, resulting in higher average performance. No crashes due to undervolting the cpu. com Jul 22, 2023 · While this guide isn’t going to teach you how to improve the performance of your laptop, we will cover how to increase battery life, reduce heat, and reduce the amount of time the fans kick in by using a technique called CPU undervolting. (Or at least until the next wallet-crunching model is released. This has the following benefits: Zen 3 gets worse general performance, and instability, from undervolting. 0v for 4. The short answer is that undervolting is the manual reduction of voltage to a CPU or GPU. The CPU currently runs at base clock only and the temp never goes beyond 75C (with cooler booster enabled), even at intense activities. With a moderate undervolt on my 3070 I get higher framerates. It should definitely be a breath of fresh air for anyone who lives in an extremely hot part of the world right now to learn that their computer can run even cooler (especially if they already thought to do undervolt their GPU) without them missing out on maybe 10FPS in a game, or even better that their CPU is much cooler while idling. Undervolting = making the CPU run below stock speeds / run at lower than stock voltages. Potential undervolting dangers include damage and instability. 875v stable without any crashes during stress test. The CPU already manages power/performance more optimal than any motherboard by itself. But when I started to play Cyberpunk 2077, it was crash galore. By undervolting, you can significantly lower the temperature of your CPU, improving both its efficiency and longevity. Because of how the i9 works, the highest boost clocks occur at the lowest utilizations where temperatures and total CPU load are lowest. Feeding your gpu less power and telling it to do the same performance seems bad, but it is actually very good for You can also undervolt and with a lot of testing/checking get to a point where you're CPU is running on LOWER voltage without any loss in performance. ounsmegwttxybvfzaclgkfcqroaokammbrkjprasnldrfchmcdzyzoh
