Copyright © 2021 GamersNexus, LLC. The only other notables are the 3600 with a -.05V offset on the X570 Master, which was slightly cooler than stock in multithreaded testing with an extremely small bump to its average score, and the 3900X with a 0.1V offset on the MSI Godlike, which was much cooler than stock in single-threaded testing but with minor performance degradation. Derweil ist der Betrieb des Ryzen 9 3900X mit einem Offset von -.1V auf dem MSI X570 Godlike möglich. These next charts are all frequency plots. I would lower your offset a little bit ( maybe at -0.0725 V) because in my opinion you are slightly reducing performance with -0.1 V, but don’t worry about voltage. Parts will arrive in a few days. In my case and with my specific MOBO (Asus C6H - x370) the different Ryzen CPUs I had (3600x, 3700x and now 3900x) behaved in the same way: - High voltage at idle up to 1.5V - (Thus) 'high' idle temps: around 37-45ºC That means no LLC overrides or anything like that, so the boards will behave differently based on how the manufacturers configured them. Funny thing is fully stock the CPU stays nearly 4GHz all the time with high voltage (low current of course), PBO Enhanced Mode 4 makes it settle more on desktop. Under heavy load the 3900X can run at 1.1v with vdrop which is a great CPU. Suffice it to say, the reports about undervolting the 3900x causing performance regression are … Override+Offset Mode is the Override Mode plus Offset voltage, while Adaptive+Offset, as the name implies, is Adaptive Mode plus Offset voltage. Snow. I haven't played with the voltage offset yet, but I did try adjusting the PPT from 142W to other levels. We didn't mess much with the mesh, but you might be able to get to 3.2Ghz with 1.25-1.3v mesh voltage. "3900x is running a bit hot and high voltage, but I figure that will get fixed with a motherboard update." Light load will be up to 1.58v depending on power plan and BIOS.I say 1.58v because it is the highest voltage I have seen.This high voltage is to get the high boost on cores.Highest boost I seen was 4750Mhz on 3800X Now as long as temperatures are within AMD limits ,I would say no problems and try not to let it bug … In POV-Ray, running the 3900X at a flat 4.3GHz at 1.35V gives it a 8.2% performance boost over stock. So how far can I take the positive offset and whats the max safe voltage and temperature for long term use? Press question mark to learn the rest of the keyboard shortcuts, R9 3900X | 2080Ti FTW3 Ultra | AW3418DW and 2x S2716DGs, https://www.youtube.com/watch?v=JscRwIH3OAY. Less voltage == less watts == longer time at boost. Hello ! As mentioned in other threads I’m currently trying to undervolt my 2700X. I run with a fairly high -0.120 undervolt offset but even with that I don't experience any stability or clock stretching. Under heavy load the 3900X can run at 1.1v with vdrop which is a great CPU. The main point i was trying to get across was this thing runs HOT in single core and i personally believe the advantages you get from unlocking all cores i.e. Οπότε έβαλα voltage offset -115mV* και επειδή πολλές φορές δουλεύει 100% για μέρες έβαλα να κάνει thermal throttle στους 77C να έχω το κεφάλι μου ήσυχο. I idle at 30 to 35 with the occasional small spike into the high 40s. My default process is undervolting via my BIOS’ offset mode and reducing the voltage step by step. Thank for your awnser, the problem is that i dont know how to change the offset voltage on my gigabyte motherboard, i just can't find the option It benefits this cooler and the stock cooler far more. I have a 3900x with the stock cooler and a gigabyte x570 UD motherboard. Remember that when the A-Phase voltage is zero, the other two phases will not be at zero, so different phases will react to the same fault differently. SoC voltage, VDDP voltage & more. Much like GPU overclocking must be validated with performance tests, CPU volt-frequency changes have to be validated with performance. So with the profile you want to set up selected, click the “FIVR” button in Throttlestop. We’ve also zoomed the frequency charts to a 2000MHz range in order to make the differences more obvious. -0.05 is the sweet spot for my setup. That was encouraging, because it meant we were hitting real limits rather than fooling ourselves by setting an unrealistically low manual vcore, so there was a chance it might actually help performance. Keep pbo enabled and use a minus voltage offset keep stepping down from 0.00625 to say 0.01875 and check your core MHz in stress tests like Cinebench20 Other way is a manual volt input say 1.3 or 1.325 but and force an all core overclock but the. Schon im ersten Anlauf knackt unser Core i7-7700K die 5-GHz-Grenze, wenngleich mit hohen 1,40 Volt. Increasing GFX voltage to 1.3V did nothing, and did not change the voltage readings at all. In the new window, tick the “Unlock Adjustable Voltage” box. The next chart shows the same type of data, except on the R9 3900X instead. R9 3900X - 4.1-4.2 when most or all cores in use. Beiträge 28. Ok just done some more testing. What about a little more? 1.4v when it actually isn't drawing much power is fine, just use a -0.05v offset, all 3900x can handle that without a dip in performance, or -0.1v if ur lucky. Launch hwinfo64 and monitor the boost clocks. Therefore the maximum DC offset occurs when the voltage is zero. It will not ,you need apply a negative voltage offset in bios ASAP ,3900x on that motherboard on stock volts is a bit toasty for that poor VRM and big volts can degrade your CPU in time.I have basically same VRM on my 2700x and with PBO I had to offset -0.1v . Now we’ve established the truth, which is that setting a vcore this low will in fact damage performance, even if that damage doesn’t come in a form as obvious as a typical bluescreen. CPU: Ryzen 9 3900x @ 4.25Ghz -0.1000 Vcore Offset CPU Cooler: EVGA CLC 360mm AIO w/ 3x120mm Corsair ML Pro R G B Fans Memory/RAM: HyperX Predator R G … All forum topics; Previous Topic; Next Topic; 5 Replies AlHill. reboot. Wir haben außerdem die Werte für einen Ryzen 7 3700X und einen Ryzen 9 3900X ermittelt: AMD Ryzen 7 3700X, ASUS ROG Crosshair VIII Hero, BIOS 0702, AGESA 126.96.36.199 AB CPU VID (BIOS) Disclaimer THIS IS MY FIRST BUILD- but i studied allot & have done allot of electronic maintenance and assemlby for a job i had with much more expensive shit. Ist das Normal für einen Ryzen 3 3900X mit einer 240er AiO? The 3900X, like the 3600, performed much worse than stock with vcore set to 1V. Produktinformationen - der8auer Ryzen 9 3900X 3,8 GHz (Matisse) pretested @ 4,20 GHz Sorgenfrei übertakten für das Extra an Gaming-Power! At stock, the Godlike performed slightly better than the Master, and the best undervolt offset we could manage didn’t significantly change either board’s score. My personal strongest results are -0.075 or -0.08125 on CPU and leaving the SoC as-is. So, if you have a processor like the Ryzen 9 3900X with a maximum boost clock of 4.6GHz, no core will ever go beyond that value. Thank for your awnser, the problem is that i dont know how to change the offset voltage on my gigabyte motherboard, i just can't find the option Hi, I need to reduce my CPU voltage,but I can't able to access the core voltage offset in Intel XTU. Produktinformationen - der8auer Ryzen 9 3900X 3,8 GHz (Matisse) pretested @ 4,30 GHz Sorgenfrei übertakten für das Extra an Gaming-Power! Latest AMD drivers with AMD balance profile. Voltage below 725 mv are not accepted You should cut the maximum possible clock rate with the curve, otherwise the card will become unstable with too high clock rates in the peak. Seems like best I can get is 4075Mhz~4100Mhz with 1usmus power plan and settings and -0.0625 voltage offset (reduces max core peak from 4625Mhz to 4600Mhz but W/E). Our conclusion is that yes, there is an easily reproducible bug where setting a vcore too low on Ryzen 3000 CPUs will cause a significant decrease in performance while reporting to HWiNFO that clocks and temperatures have improved. 130W resulted in max boost clocks of about 3.9-4.0MHz instead of the 4.1-4.2 that I got on stock settings. What mobo and ram are you using if you dont mind me asking? When leaving everything else stock, setting a small negative vcore offset helped more and yielded more predictable behavior than setting a straight manual vcore, but the benefits varied by CPU, motherboard, and workload. We recommend decreasing this to “-100mV” to start. For me the offset was the best thing I have done to boost performance and reduce temps. Go back -0.01 or -.015 from the offset value that you got the reduced score in. Εκτός αν ζείτε σε Igloo. 1.4v when it actually isn't drawing much power is fine, just use a -0.05v offset, all 3900x can handle that without a dip in performance, or -0.1v if ur lucky. 0.1v undervolt and faster than this guy's stock 3900x using completely different benchmarks than the other 24 tests run against myself. The reddit post was itself a response to a video where a YouTuber claimed to be lowering temperatures and boosting performance on Ryzen 3000 CPUs by lowering the vcore value in BIOS; we never did catch the video, as it has since been retracted and followed-up by the creator and community with new information. I recommend a Small undervolt for a little performance. 3900x and Asus C8H. ... there is no thermal offset, so the temperature reported is the correct temperature. The ability of the generator(s) to react to the fault and time necessary to stabilize the system. I’ve higlighted the Ryzen 7 2700: Enhancedcategory (there’s another category called “Ryzen 7 2700” that doesn’t have temperature or power consumption that we’ll ignore) 2. There will be some delay after submitting a comment. It’s also possible to tweak voltage down on our 3900X for some very minor benefits. Voltage offset is your friend. In POV-Ray, running the 3900X at a flat 4.3GHz at 1.35V gives it a 8.2% performance boost over stock. Since Silicon Lottery tests AVX2 loads, the CPU max frequency will be rated for practically the worst-case scenario. Single-threaded scores were largely unaffected and actually decreased slightly on the Godlike board with the voltage offset, so the -.05 offset for the 3900X on the Master is the best combination we’ve tried. These charts show VID instead. Stock vcore for the R5 3600, shown here, was reported as about 1.39V under all-core load or about 1.344V with the negative offset applied, and both fluctuated between 1.38-1.4V in the single threaded test. One-point-zero is a ridiculously low voltage to run for Ryzen 3000 CPUs, but both boards and both CPUs allowed us to set and boot at this voltage. cooling them will keep it cooler in the long run and the cooler electronics work the better theh operate so my focus was temps -> then frequency-> THEN backing down voltages which reminds me it is at 4.1GHz or 4.0. I seen this alone with the crazy low voltages they report. Post yours. I was only monitoring cpufreq of cpu0 so you dont get to see the max pbo across all cores but that gets too messy to view when you're viewing 24 cores. Since AMD doesn’t specify voltage, since it varies based on workload and boost frequency, I’ve attempted to specify the most common voltage seen during a similar load (Prime95). I have a 3900x with the stock cooler and a gigabyte x570 UD motherboard. We did this stock, set to 1V vcore in BIOS, and then with the best negative vcore offset we could manage, which was usually .05V. In theory you could tinker further using this method; reducing the voltage further may allow for cooler running, and you may have more luck in increasing frequency, it really comes down to the “silicon lottery”! Like way too high. 5 or so cores regularly hit that 4.6 plus. Limit your EDC to 140 as well. I noticed a number of sites and channels are reporting that the AMD Ryzen 9 3900X 12-core, 24-thread processor can be run at full clock speeds with just 1.00V on the CPU VCore. will cause the requested voltage per core (VID) to rise in response so that the end result is nearly the same. It’s very easy to trick yourself into thinking all the numbers are better, but actually sacrifice performance. Consider adding a negative voltage offset. The reason why we’re interested in max values instead of so… Your ccx2 will be not as good silicon as the ccx0 so will hold you back. Mein Wert liegt bei 4866. Ideally though you should aim for no more than 1.4v and 80*C. Turn AMD Cool n Quiet from Auto to Enabled. I've gone more aggressive but this one is fine. Congrats, you've got clock stretching. PBO enabled. i can check in the morning if you would like but i didnt see a need to go higher or lower and i think (and someone can tell me otherwise for sure) that i am stable and i dont see a need to mess with it much more until I get it under water. I'm not sure what you mean by "took it off single core", but there's something amiss with your setup I fear, you shouldn't be idling at > 60C. I run with a fairly high -0.120 undervolt offset but even with that I don't experience any stability or clock stretching. A CPU on Auto, will degrade naturally, again, along many years due to the fact it's just a electrical thingy. On the R9 3900X, clocks were less constant, but it still reported holding higher clocks than stock with 4225MHz during the multithreaded tests. The 1V BIOS setting works according to software logging, although the next batch of charts may contradict that. But also, I have seen recommendations of - 0.05 offsets. The 3900X showed the inverse, with stock and offset results both sticking to about 1.27V in the all-core load, and the gap showing itself instead in the single-threaded pass with stock vcore hitting 1.47-1.48V and the offset voltage holding at 1.39V. We also ran Blender and logged frequency, but the Cinebench numbers are plenty for now. Set voltage to auto - don;t worry about offset. The average core VID numbers stack up differently than the reported vcore. I haven't build it yet. Reboot and increase the offset by -0.01 (so to -0.06). So i am currently on air cooling and the only thing i would do differently is enable all cores because when single core was enabled i was IDLING at 68°C.... on my desktop... with JUST afterburner downloaded n running. It seems that Auto means off. Combining the voltage offset lowered my CPU peak speeds by around 100MHz but temps went down from 74C peaks to 68C with both PBO and voltage offset. If you don't know what that is you need to watch this video: https://www.youtube.com/watch?v=JscRwIH3OAY. 3. There’s an unholy number of charts that could be generated with the data we’ve gathered, so we’ll be focusing on the MSI Godlike board for most of this piece, just because the graphs for it are a little easier to read. Ich habe meine CPU AMD Ryzen Threadripper 1900x auf 4,2 Ghz übertakten und die Vcore Voltage auf OFFSET + gestellt und er zieht unter 100% Last 1,50 VCPU ist das Normal das diese CPU so viel Volt zieht ?
