Hardware. Hello guys, i recently posted a thread about having high temps running this laptop on games. Buenas, últimamente tengo un grave problema y esque con cada mínimo proceso que haga mi ordenador el procesador se pone a unas temperaturas altísimas de 70-80°, he formateado varias veces pensando que podría ser algún tipo de virus minero, pero el problema persiste, he detenido procesos como Windows update In the case of your 5900X, you'll see perf 1/1 (best core) all the way down to perf 11/12 (worst core). I normally do the regular Clock + Voltage adjust in bios with previous ryzen, but everyone seems to be praising the PBO curve. But when when I got elden ring I started to get whea errors. I have a 12900k in 3. Hello friends. 2 Samsung 960 pro 1TB SSD So what happens if you undervolt the CPU. Controversial. Has anyone had any luck with undervolting on this combination? 30, 25 and 20 tics of negative offset still resulted in reboots at idle or light workloads. Lian Li Lancool II mesh RGB(upgraded stock fans to Bequiet 4 x 120mm and 1 x 140) Ryzen 9 5900X Bequiet Dark rock pro 4 Arctic MX-4 2019 edition thermal paste MSI B550 This guide helps you undervolt your new Ryzen 5600x 5800x 5900x 5950x CPUs. Give it a try. Yes, you want these voltages as low as possible, but as high as necessary Hi all just wanting to compare my new results of the undervolt of my 5900x on Asus x570 strix-e. The boost algorithm is temperature seeking so it will always try to reach the same temperature but with an undervolt it hits same temperature at higher clock frequencies. My system: 5900x Noctua NH-D15 Chromax with two fans MSI X570 Tomahawk Wifi 32GB 3600 CL18 Asus Tuf OC 5900x ultra undervolt help needed Hi all, i have 5900x running as a plex server about 16 hours a day. My i9 10900k would run high 20s or low 30s at idle with the same cooler and paste. 95V instead, and whatever frequency is mapped to 1V is now >2GHz. Oct 10, 2023 #1 CPU Cooler: 240mm Coolermaster v2 AIO I use a 5900x for a year now with a NH-D15 with Kryonaut and it is 35-40C at idle and while gaming and sometimes streaming it goes to max 60-70C depending on what exactly I play. It's part of the PBO2 settings (google it) and I found that to be a better way to lower temps without affecting performance. Also, look into PBO with Curve Optimizer, which can also be used to undervolt, but takes some work to get stable. Additionally, undervolting can cause your motherboard to run at a lower clock speed, which can impact performance. Technical Help I have a 5900x running on an Alphacool LT240 and currently have: 60C Idle temps on 50% fan speed 70-80C In game temps on 100% fan speed 90C(thermally limited) When running Cinebench R20( 8500ish MC score) on 100% fan speed PBO settings: Curve optimiser -14 on best cores -17 on 2nd best cores So just getting back into the team green swing with this 5900X. In idle it sits around 1. The thing is, slight differences are always to be I've followed a YT video about undervolting my 5900x. 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. A -10 all core is more than stable to what I've seen. On stock settings, the cpu goes 50-55 degrees on idle. Top. If it gets unstable and crashes, try -0,075 or -0,05 Also undervolt by using offsets and not a fixed voltage. 9L case. core offset + frequency/voltage cap). Stress testing was All Core cinebench R23 looped for about an hour. Add a Comment. 1Ghz, max temp is below 70C in 3d and video rendering. 069 pretty much sweet spot So I have a Ryzen 9 5950x in a custom waterloop with two 360 mm radiators. 48V, full load drops to 1. It's working fine at -30 across each core. Reply reply On my 5900X I did custom boost of 75mhz, and -20 to -15 on my non best cores. 4 voltage often. But since you're also running a sff system my suggestion is to let the limits at stock, use curve optimizer to undervolt and squeeze out last bit of performance, and tweak your fan curve to keep constant below 75C, and really ramp up hard above 85C. Do I have a bad CPU? I would prefer to not undervolt it. At this point, if you can use a browser, you can undervolt. If you want to lower your CPU temps, just set a temp limit you're comforatble with and undervolt as much as you can while For instance, my 5900X is sitting under an Alphacool Eisbaer 420, and depending on the limits I set, the max temp will be: Under ECO limits (the chad mode) - max 60C Under normal limits - max 80C if i undervolt my 5950x while keeping Quick search for 5900X suggests this this. New comments cannot be posted. Even that is pretty much a nothing burger. During gaming sessions, I realized that the temps of the 5900x usually hover between 66-70 Celsius, however there's random short spikes in the mid-high 80's. If it was somehow (by an extremely bugged, unsafe board) made to run at a fixed 1. Undervolting your CPU is tricky and requires many tests to get to stable settings like for overclock. This was assessed via HW Monitor. It's literally the design of the chip using PBO to go to the limits safely below 90C. I took the OC off my VRAM and slightly changed the undervolt and all was good. Reply reply [deleted] Sure if you are still stable (frankly with lower core zen 3 variants undervolting is easier than with 5900x or 5950x) then yeah job well done i guess, but yeah my point is that undervolting is entirely different beast than your usual intel OC, 5900X undervolt with curve optimizer, keep stock wattage? Discussion All of the info I can find suggests setting limits to "motherboard" which pretty much makes the sky the limit on power draw. My AsRock B450 board has lots of Help Request - RAM 5900X Undervolt and OC -- Cinebench Scores Hello, does anyone here where i can find a guide to undervolting and OC? I did some from the faint knowledge i have here are my results: Undervolting: set to offset mode -.

But until then the boost was up to 4950 and temps were down a good 10c as was the total power consumption. My first 5900x couldn’t even do -5 all core. pretty much garbage chip :) It's a bit counterintuitive, but best chips already run very efficiently and have little undervolt headroom :) So good chips will go For my 5900x, PBO at -10 helped get it to around 87, when playing stuff like modded Fallout 4 which seems to really hit my CPU harder than Cyberpunk. With cores #4,#5 respectively at 20 & 15. To mitigate these risks, it’s important to undervolt your motherboard carefully. System is "stable" in the sense it's been doing hours of GPU, CPU rendering, stress test without issue. Cooling is Arctic II Freezer 240. Undervolted to -30. Cinebench r23 results are consistent between 20 and 21k score. What I was looking for was undervolt but overclock; something similar in Do it in the stock turbo mode. Switching on that setting gave me the same if not greater boost in temps and performance like you are having with PBO2. The performance jump felt amazing, but the temps felt way beyond ridiculous, and I was getting BSOD every other day. 1. Need help on how to undervolt my 5900x How to undervolt a ASUS G17 AMD Ryzen 9 5900 HX RTX 3070 . Used +200mhz and -20 on ASUS b450i on two best cores. Temp doesn't kill the CPU, current (high voltage at high wattage) does. 3kh and 3. Coming from a water cooled vega64 that is nothing. (Motherboard limit) but in AI Tweaker I can go higher. Anyway, I set an undervolt of 1. I have done some research and it seems like undervolting could be an option to improve temps and performance other than re-pasting 5900X under boost load all core is closer to 230w. Prime95 on Ryzen 5900x - Temps upvotes Basically, a 50mV undervolt tells a CPU that instead of operating at, say, 2GHz at 1V, operate at 2GHz at 0. Thanks It is only clear to me that I have to open the program and click on the UNDERVOLT button. Hello, I have a problem with my 5900x I have high temperatures between 76-83C+ in games. 9% Base Cinebench r24 multicore : 1057 After : 1094 3. I dont care at all about noise level. This yields 13,260 points with 74C max on a 30C ambient room in a 10-min run of Cinebench R23 using a Thermalright PA120 cooler. I'm prioritising lower noise levels over performance gains to Use PBO2 + CCO undervolt. A 5900x dropped from 144w PPT to 95w PPT only loses like 10-15% performance in multicore. Can someone give me settings for the PBO? My Setup: Corsair H150i elite Capellix 360mm Pull&Push 6x Fans (Exhaust) Mainboard: Asus x570 E-Gaming Case Fans: 6x Corsair QL 120mm (Intake) PSU: Corsair HX1000 Lian Li o11 Dynamic Asus Strix 3080ti OC Monitor Alienware AW27D1 I finally have a rock stable OC on my 5900x! 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 The latest bios for that motherboard has kombo strike support. But I don't know if I have to modify any value before clicking on the DIAGNOSTIC button. New comments cannot My 5900x took all the curve ever, and performance still dropped above +100, so it seemed to confirm that step 1 accurately identified the boost threshold for the chip overall as opposed to single cores that might be able to go slightly higher AMD Ryzen 5900x; ASRock X570 Steel Legend; 32GB C17 Memory; 750w PSU; 240MM AIO from BeQuiet.

Cpu cooler used on both cpu chips is the Coolermaster Hyper 212 RGB Black In the realm of PC optimization, undervolting has emerged as a sought-after technique to enhance performance and efficiency, particularly for high-performance processors like the AMD Ryzen 7 5800X. ? And is it clever to turn on/off PBO? Lower PPT, TDC, EDC works apparently great for some people but only for cinebench score. I mean, it's also 200$ more and the 5900x is My last 5900x had to be RMAd for a constant reboot issue at stock settings and couldn’t do any undervolting but hit 5. First, you are reducing the maximum operating frequency of the processor. I like a cool and quiet chipif I wanted to keep draw still around the 140w stock wattage would I leave the limits the same and still try a negative 5900X oc or undervolt options My end goal is to keep the temperature as low as possible while keeping at least stock performance. You can further drop the voltage with a vcore offset if you have a good chip. I used Kryonaut thermal paste. Find your strongest cores, set those to like -6, the rest -15, test with y-cruncher / Corecycler, if stable, lower the numbers to like -12/-20 and just test. 18V. Undervolt ryzen 9 5900x Benchmark Score I do some tests on Amd ryzen master and I have very good results, I don't push too far. When I built this I had an issue with CPU temps due to the cpu getting 1. 3GHz, all because the CPU can boost higher within its power limits. And I found that to be very suspicious. Found a good video on setting up an undervolt with PBO2 last night and ran with a negative 30 for a few hours last night gaming, got one BSOD. Or do this try only enable pbo and lower undervolt from 0. Set PBO2 Curve Optimizer to -23 with PPT 110 and Maximum Processor State to 99% on Windows. Previously his PC would crash 100% of the time within an hour on games like Rust or Baldur's Gate 3, after the undervolt he could play Rust for multiple hours.

Ultimate guide to undervolt Ryzen 5000 zen 3 CPUs. Even so, I have been researching for a while and I see that many Ryzen owners recommend doing undervolt since it improves performance, consumes less voltage and therefore lower temperatures Ok, I have about 5°C lower temps (at idle & full load) than you, with cheaper CPU cooler (on 5900X). Oct One thing I've found, at least with my 5900X, is that undervolt-related instability happens at lower/idle clock speeds more often than higher workloads do even with Eco mode on and PBO to auto. A real undervolt would be to play with the EDC, TDC and PPT, but you would limit the performance of the chip where Curve Optimizer can actully increse the I have no idea if it's even close to the same as 3000/5000 series but all I do is set the CPU core voltage to offset - ( negative ) by 0. A friend of mine got his 5800x, but we would like to undervolt this specific CPU to give it a bit more headroom with temperatures (It reaches 90 to 92 degrees celsius while gaming), but sadly I can't really find a comprehensive guide of some sorts which settings should be adjusted. PBO is on, LLC level 3, voltage auto. You're not even close on the numbers. Should i bother with undervolting?
