Undervolting cpu reddit. In addition, the undervolted CPU seemed more inconsistent with the results. I had an offset of -0. Used my bios curve optimizer to undervolt -30 on all cores. 9-4. i did bios modding. Question for those that have undervolted CPU: I have ran benchmarks at -30% undervolt and the cpu ran without issue. 2. I agree if you don't care about finding the perfect undervolt then you can just leave it and it's probably fine depending on your cooler but as far as I know playing with undervolts is completely safe the only thing you risk is as you said instability which you can fix by changing it back to stock if needed. Other users have been kind enough to jump straight to testing those higher undervolt values, it's good info to have. Zen 3 gets worse general performance, and instability, from undervolting. Intel has also disabled undervolting on 10th-gen CPUs in response to a vulnerability called “PlunderVolt”. I don't know if it's the best but I learned a bunch from it. This is without undervolting at all. For PC questions/assistance. When asking a question or stating a problem, please add as much detail as possible. 5ghz). 0GHz on E-cores during Cinebench, your temperature with undervolt will stabilize below the 100°C it would be without undervolt. Especially considering the government has recently requested people to lower their power consumption due to the current heatwave. Is there a better way to undervolt the CPU? P. While you can adjust voltages on your laptop a few different ways, the easiest method for Intel-powered machines is with ThrottleStop. Undervolt will slightly reduce package power (prolly less than 10% under any gaming load), temps drop by 4 or 5 degrees, and cpu will try to reach a tad bit higher frequency. However, would it be in my best interest to undervolt both? I know the GPU is probably a yes, but how about CPU? For the CPU, sure is. At that TDP the CPU settles in around a 2. Ran cinebench r23 and got 4450 mhz boost block and a score of 14943. Gpu temps have always been great, cpu temps are a little high but not dangerously so I don't think. Would anyone who knows much about undervolting For example, let's say your CPU has a max power limit of 45W and the stock frequency is 3. The CPU currently runs at base clock only and the temp never goes beyond 75C (with cooler booster enabled), even at intense activities. Overclocking is safe-ish (provided you can cool the extra heat without issue), though it's largely pointless on modern cards. 8GHz by the square of the voltage (power = (voltage^2) / resistance) so now it may only need 40W to run 3. Simply just booting up the game would crash it. If it is power savings you seek have a look at the CPU PPT setting. Undervolting can make performance more consistent, resulting in higher average performance. Looking at guides online the writers all say its "generally safe" but don't specify any risks involved. Yes, in that you won't damage your hardware. If you drop voltages far enough you will get crashes. The setup may be unstable with lower voltages at certain clockspeeds, so you may have to play around wit Nope, i just don't really need more CPU power atm, and performance contra heat contra speed didn't really make sense, so the sweetspot its fine their, plus i am running air cooling in my Rack setup, so i am restrict to 150mm CPU cooler height. Speaking for myself, to quell curiosity & know what the limit/undervolting headroom the Cpu on my notebook is capable of. 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. On the flip side, I can't consider system constantly running 90+ degrees Celsius as stable, just because the manufacturer decided to put more voltage to the CPU. Having a cooler that's even slightly off will create a microscopic gap and introduce a couple nanometers of air on one side in between the CPU and heatsink. Stable version will have a section called, "CPU Overclocking", click there, It has undervolting Alpha Version(s) have a preset for your CPU, click on performance mode BEFORE undervolting as it allows us to undervolt harder, I was stuck at -10 and got to -25 stable. Dear all, I am considering undervolting my laptop to improve battery life (both cpu and discreet gpu). For AMD-powered laptops, you can use the Ryzen Controller to lower the temperature limit for an automatic undervolt. 10 votes, 35 comments. . 000, even though I've set it to be equal to the CPU Core. If you want to limit your CPU to 60W for example you can set PPT to 60W and your CPU will limit itself to that power target. It is like overclocking but instead of maximizing performance you are minimizing the power consumption and therefore the heat generation. This MAY allow the CPU to increase its boost clocks - depending on hits voltage:frequency curve. The CPU already manages power/performance more optimal than any motherboard by itself. The same principles applies where you need to balance the voltage and clock speed up against the cooling capacity and stability of the CPU. I was a gaming laptop user until recently. When I thought about undervolting and fell down the research hole, I stumbled across this video -- dude does a bang-up straight-forward no-nonsense presentation on the subject. My undervolting and overclocking experience mainly comes from AMD but I'm fairly sure Nvidia deals with it exactly the same way. Meanwhile it immediately crashes with undervolt upon booting into the game from the main menu. When you undervolt you are reducing the power usage at that 3. g 1800, these clocks can drop all the way down to 4. Undervolt makes the processor more efficient, consuming less energy to perform the same task with the same performance (same clock). Hello everyone. GPU Undervolting Guide | Nvidia RTX 3080 Ti | Step by Step How To Guide Thank you, the starting voltage is at 900 mV because I believe that going any higher is not really an undervolt and if you do decide to go higher, it would be more of a situational thing rather than something I could recommend as a baseline. Let's talk modern CPU overclocking, if you want to talk overrated. Also load doesn't matter with undervolt, because curve offset is for all sorts of loads, low, mid and high - being and OFFSET it affects voltages at all times including even idle, that's why you test undervolt with core cyclers or other tools testing mixed loads and going thru individual cores, rather than evenly slamming all at once (like Undervolting lowers the voltage use given a certain frequency. For Throttlestop, run the benchmark at size 960M and if it completes without a BSOD then you'll know that undervolting value works. No crashes due to undervolting the cpu. Core 0 | P-State Limits (non-turbo): Highest: 0 ; Lowest 2 | Current P-State: 0 Pstate Status CpuFid CpuDid CpuVid CpuMult CpuFreq CpuVolt IddVal IddDiv CpuCurr CpuPower 0 1 148 8 70 37. I'll undervolt soon, I'm scared as hell to do it cuz I'm really not techy as well. This Subreddit is community run and does not represent NVIDIA in any capacity unless specified. Generally during my cinebench loops the CPU will initially try to sustain around a 30W TDP for the first 20-30 seconds of the initial Cinebench run before then power-throttling and settling down to a 15W TDP. The cpu is water cooled, gpu is not. 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. 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. I did 150mv undervolt on cpu core and down clocked it to 3. 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. Updated my bios and read online to undervolt to get the chip to reach its boost clock. That's the advantage of first doing it in the Intel tuning utility is it's applied after you're in windows, and damage to the CPU doesn't happen with undervolting it just isn't getting enough power to run. mv undervolt of p core and e core and cache of -125mv liquid metal on the cpu and 4090 gpu but temps still hit 80c while gaming and 92 to 94 cine bench but that vid is crazy. 2 GHz at 1. g. Now, with a massive undervolting, it finally got a chance. But there is an inherent minimum the voltage must be at to actually get the CPU to clock as high as you want it to without crashing your system. You're not breaking the CPU when you crash though. 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. Throttlestop doesn't seems to work with my current PC either (Core Voltage options are all greyed out). 5GHZ sustained clock and hovers anywhere from 68-72c in terms of temps. 8GHz max got great reduction in temperature (10-20C) i use my… I have mine unlocked on alienware. 00x 3700MHz Eventhough my CPU can easily do 2000Mhz FCLK stable, actually using it tanks my clocks. 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. Undervolting was a common way for users to get more performance out of their laptop CPUs. Just got a 5800x3d. My question is, how exactly do i know the undervolt is stable? I ran a few games like cyberpunk and no crashes well in the links above i believe the var names is overclocking lock as the yt video and the tutorial and even some poeple commenting mentioned that but i didnt find anything in UEFItool its either the BIOS backup utility didnt read the bios well or the var name is different or UEFItool isnt appropriate for this task (i tried 2 versions from differnebt downloads to make sure that it hasnt any A place for everything NVIDIA, come talk about news, drivers, rumors, GPUs, the industry, show-off your build and more. 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 Yeah, but my CPU is different from yours and will likely need a different value. 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. You can specify Wattage there. But when I started to play Cyberpunk 2077, it was crash galore. 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. Recently got my first ever gaming laptop, an Acer nitro 5 AN517-52-5744. When undervolting, the worst that can happen is your CPU/GPU not getting enough power and turning off the computer. Most every board from an AIB is clocked as high as it will stably run at its ra Undervolting allows a CPU to run cooler because less voltage. , 4. Re-install your CPU cooler to make sure it has even pressure on the CPU heat spreader. That's why it's important to do appropriate testing during this process. Preview mode On - No P-State values will be changed. Voltage ID encodings: SVI (serial) Detected CPU model 21h, from family 19h with 24 CPU cores. 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. e. You can gain efficiency by limiting PPT and combining that with a light UV. Undervolting is really one of the best options to lower the temps. Undervolting is safe-ish; worst result is instability. That's cool and all. My CPU doesnt appear to be thermal throttling so I am not sure of the reason for this behavior. idk which one to trust. Jul 14, 2024 · If the AC tells the CPU it should expect "x" Vdroop under load, while the LLC allows for "x+5" Vdroop under load, then the CPU effectively gets more undervolted the higher the CPU load is. 05V for the 4090), there's literally no risk except for time. It actually does work, before without it the i5-9300h would only do 3. 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. (CPUZ) I ran the tests multiple times to confirm the results. For example, a 7800X3D will only ever be able to hit its 5050Mhz boost clock. 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. And for reference if you undervolt too much it will just crash and revert to stock settings on next reboot. Say CS:GO is very close to what valorant is, my CPU temps are close to idle 40-55C, when i run that. It's mainly for temperature because this CPU is known to be hot. 350V for the 13900K, and something like 1. Using Throttlestop, I've set the CPU Core and Cache offsets to -95mV, but upon hitting "Apply," only the CPU Core offset actually shows a change in the top-left graph; CPU Cache offset shows +0. Before undervolting, it can not reach the max frequency because it throttles. S. So at the same performance you indeed use less power, and as a result you also generate less heat. 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) Just got a 5800x3d. A CPU will only ever hit its imposed boost clocks per their product page. 6 Undervolting is a process which reduces the excess "voltage" given to the CPU using a software. 15625V (Ryzen Master) Despite what Ryzen Master says, my undervolt is stable, CPU-Z shows results above average for my chip, my idle temps are no longer jumpy and overall lower. r/Undervolting: Your go-to subreddit for undervolting your CPU. CPU usage will be heavily affected by the GFX intensity. Undervolting doesn't usually reduce performance, it reduces stability at a given clock speed. 5GHz on P-cores and 3. You turned the voltage down, this lowered power at a given frequency, so you can get more performance in the same power envelope. That leaves me with the BIOS option. That's why undervolting by lowering the AC load line is so effective when benchmarking or running heavy loads - it hides from the CPU the fact that Vdroop is May 10, 2024 · Undervolting your processor (CPU) can bring huge benefits but it has to be done correctly for your PC to function well. My question is, how exactly do i know the undervolt is stable? I ran a few games like cyberpunk and no crashes well in the links above i believe the var names is overclocking lock as the yt video and the tutorial and even some poeple commenting mentioned that but i didnt find anything in UEFItool its either the BIOS backup utility didnt read the bios well or the var name is different or UEFItool isnt appropriate for this task (i tried 2 versions from differnebt downloads to make sure that it hasnt any The CPU currently runs at base clock only and the temp never goes beyond 75C (with cooler booster enabled), even at intense activities. Only thing happening is you get happy numbers in HWINFO64, but performance tanks. So i'm on a Legion 7 Pro with a 13th Gen i9-13900HX, 32G DDR5 RAM and RTX 4090. 15 on my i7 13700k and playing The Witcher 3 was perfectly fine. Make sure to stress test just like you would for an overclock. Undervolting = making the CPU run below stock speeds / run at lower than stock voltages. 8GHz at 45W but your CPU specs say it can boost up to 4GHz. Increasing it allows higher total wattage drawn and increases heat, which lowers the temperature ceiling at which your CPU is stable at a given frequency. Check out our guide to CPU undervolting. When undervolting, you click on - Negative, and any number between 1 and 30. Nov 30, 2023 · How to Undervolt Your Laptop CPU With ThrottleStop. Valorant at best is has visual fidelity of mobile game, as well B4B has insane amount of character rendering (100s of zombies, all in client - server environment). Changing the offset undervolt back to default stopped the crashes. Electricity prices in Japan have risen nearly 40% from last year. The nice thing about undervolting is that as long as you're going UNDER the default voltage (which if memory serves is right around 1. They say it takes low power, so there's less stress on CPU and the temp stays down as a result. But i feel like I'm not using my CPU at its full potential! I heard about Undervolting before. Yes, if you undervolt your CPU too much, you may experience some stability issues, obviously. Generally, yes it would be prudent to start with the pre-definded range that Asus has set in system Bios. My rx 6600 draws 120 after undervolting, 40w from the cpu, maybe another 40 or so from the other stuff, it's very economical. With everything on default I can maintain a good 4. In the past I used Throttlestop for undervolting, it worked until Intel decided to kill it with the Plundervolt fix. ☠️ I've managed to undervolt my RTX 3070 from 1080mV to 975mV but I'm not sure if I do it right. I've been running Dark souls and getting temp spikes above 80 on both GPU and CPU, so i want to learn how to undervolt. Undervolting is a way to tune your CPU. My own results of applying an undervolt using PBO curve optimizer (no other PBO settings) actually showed a slight decrease in both single core and multi core performance. What you're risking is stability. But consuming the same as before. I've watched some undervolting tutorials on YouTube but some people lower the Core Clock speed by -250, some -120 and others don't reduce it at all so I'm kind of confused about this. You want to take special note of the temperatures of all your cores as well as the Start at -10 and work your way down. My settings are: 4. This is exactly what happens to me. If you have a specific Keyboard/Mouse/AnyPart that is doing something strange, include the model number i. Or right after loading a saved game. 8GHz. Voltage doesn't affect performance, it changes the parameters at which a CPU is stable. May 10, 2024 · Step 3: With HWMonitor running, run your CPU-Z benchmark and take note of the figures that HWMonitor shows. I have a Ryzen 9 5900x and an rtx 3080, but it is crammed into a micro ATX case. When you undervolt you effectively alter a curve that determines how much current the GPU uses at a certain frequency ('speed of the GPU'). As a result, you may see a lower voltage, an improvement on the CPU frequency, and a thermal throttling CPU. throttlestop 9. Sep 22, 2023 · If you limit the clocks to, example, 3. 5 ghz with 100 degrees but so far with this configuration -160 core, and -170 cache it does 3. Keep going until you find the highest one that doesn't give you a BSOD. However, what I have done was to turn off the turbo boost which lowers the temperature but also the performance. I've been experimenting with undervolting my Ryzen 5 3600 on my B450M Steel Legend to reduce noise. 4GHz on all cores, but even with a mild fclk increase to e. Overclocking = making the CPU run at a faster than stock speed (e. ihxptilbbrrxbvserhijuzrumskukwelxcpiezgoxahjrxlxg
