The ability of the generator(s) to react to the fault and time necessary to stabilize the system. As mentioned in other threads I’m currently trying to undervolt my 2700X. MB Asus x570 - e and RAM 3600 8x4. 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. I think i might have seen the temps jump to like 72°C while playing but it is a small 3 sec at most spike from mid to high 60's . /r/AMD is community run and does not represent AMD in any capacity unless specified. SoC voltage, VDDP voltage & more. 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. R9 3900X - 4.1-4.2 when most or all cores in use. Only 6% of Ryzen 9 3900X’s tested by CPU retail site Silicon Lottery are able to reach 4.2GHz manual all-core overclock. 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. This actually only dropped benchmark scores by less than 5%, but didn't change the CPU temps by any noticeable amount. 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. Here’s our first two charts, we’ll just take turns putting them on the screen. These next charts are all frequency plots. Last edited by ZER0_K%; Apr 24 @ 4:25pm < > Showing 1-15 of 19 comments . will cause the requested voltage per core (VID) to rise in response so that the end result is nearly the same. 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. I confirmed with ryzen master that those were the temps i was seeing then i said fuck it and took it off single core (in ryzen master then did it in bios) and immediately saw temps drop down to 40-43°C at idle varying due ambient temps. You're supposed to watch temps under heavy load, not while idling. So let's see some actual real measurements. Lower temps and better benchmark scores. We controlled vcore in the tests that called for it, we applied XMP and custom timings and voltage to the DRAM, we maxed out fan speeds and kept ambient temperatures and cooling as constant as possible, but otherwise we used the motherboards’ auto settings. Launch hwinfo64 and monitor the boost clocks. Always used to OC my chips but having a play here it doesnt seem to have much point in even messing with OC as results arent much to talk about for the effort. I idle at 30 to 35 with the occasional small spike into the high 40s. My 3900x tops out at 4.650MHz and 1.506v. Hi, I need to reduce my CPU voltage,but I can't able to access the core voltage offset in Intel XTU. You can do something about the latter, ... AMD Ryzen 3 3300X vs 3600X vs 3700X vs 3900X Gaming Performance. 5 or so cores regularly hit that 4.6 plus. you can do it by setting the offset value to -0.05 and run a multicore r20 test and then write down the score. Offset Mode adds the offset voltage that you set to default voltage. I have a 3900x with the stock cooler and a gigabyte x570 UD motherboard. Turn AMD Cool n Quiet from Auto to Enabled. Keep doing increasing the offset and running the tests until your score decreases. 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. What about a little more? Profil Beiträge anzeigen Private Nachricht Blog anzeigen Kabelverknoter(in) Themenstarter Mitglied seit 05.03.2014. 3. 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. Voltage offset is your friend. Not random readings. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Threadripper, EPYC, Navi, the next-gen consoles, news, rumours, show-off your build and more. Under heavy load the 3900X can run at 1.1v with vdrop which is a great CPU. 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 Increasing GFX voltage to 1.3V did nothing, and did not change the voltage readings at all. … I cant remember the voltages i am set at, but it is low like.. 1.1x. The 3900X, like the 3600, performed much worse than stock with vcore set to 1V. I don't trust any of the programs readings. On the R9 3900X, clocks were less constant, but it still reported holding higher clocks than stock with 4225MHz during the multithreaded tests. 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. 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 am receiving my 3900x in a few days. It’s very easy to trick yourself into thinking all the numbers are better, but actually sacrifice performance. Overclocking-Guru Roman "der8auer" Hartung (sprich: "der Bauer") hat sich in Zusammenarbeit mit dem für den Sockel AM4 vorgeknöpft und deren freien Multiplikator genutzt, um die schon regulär sehr hohe Taktfrequenz von 3,8 GHz noch weiter anzuheben. For me the offset was the best thing I have done to boost performance and reduce temps. Sure 50-60 idle is kinda too much, but then it shouldn't stay at 4.2GHz while idling as well. No other background processes like updates or anything. I posted mine. Ryzen 9; 3900x heat, voltage and frequency issues thank u all. Auch wenn es hier nicht wirklich reingehört aber hat einer mal testdurchläufe gemacht bei cinebench r20 mit einem 3700x, energieplan v4 und offset auf -0,1 volt? To paraphrase Reddit user Boxman90’s response post, lowering vcore a little bit without being in OC mode (locking the clocks, etc.) Reply. I've tried numerous settings turning core performance mode on, under volt off-set by 0.1 on the CPU, setting load line calibration, changing various PBO settings (tried setting the PBO power settings to 1000 and the clock was stuck at 3775Mhz) and none seem to boost it higher. 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. Trotzdem sollte die CPU nicht ins Temperatur Limit laufen, vor allem wen man Highend Kühlkomponenten einsetzt. Ok just done some more testing. 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. In the new window, tick the “Unlock Adjustable Voltage” box. Voltage offset is your friend. It’s up to AMD to explain why their CPUs do what they do; what we’re attempting to do in this piece is replicate the behavior and see if we can find a way to undervolt effectively. 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. I haven't played with the voltage offset yet, but I did try adjusting the PPT from 142W to other levels. So i re applied thermal paste after cleaning, same thing, then i swapped out the prism, used a cooler master hyper 212 evo, and was still at 66°C. We also ran Blender and logged frequency, but the Cinebench numbers are plenty for now. 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. We recommend decreasing this to “-100mV” to start. 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 I seen this alone with the crazy low voltages they report. I’ve highlighted all the sensors in HWiNFO that we’ll be using during our benchmarking A few notes: 1. All forum topics; Previous Topic; Next Topic; 5 Replies AlHill. AW: i5 2500k - Offset Voltage immer über 1.4V Ich lese es mit HWinfo64 aus. Lowering vcore a lot will initiate “clock stretching,” with the result that monitoring software will report normal/higher clocks while actual performance drops. Not long got hold of my 3900x - coming from Intel historically I am trying to get my head round how it works! But also, I have seen recommendations of - 0.05 offsets. 0 Kudos Share. Using a slight negative offset voltage with low LLC as @coercitiv suggested earlier should also work with the temp limit. 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. Parts will arrive in a few days. Do you agree? As mentioned earlier we’ve chosen not to include the results we gathered on the X570 Master board, but they back-up all the results we’ve shown for the Godlike so far. For me the offset was the best thing I have done to boost performance and reduce temps. 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. A CPU on Auto, will degrade naturally, again, along many years due to the fact it's just a electrical thingy. Mein Wert liegt bei 4866. It may be voltage, power or temp, or a combination of the three. Most of the time those programs won't even pick up a - voltage offset. In this video, we’ll demonstrate how to know when undervolting is working versus not working, talk about the gains or losses, and get some hard numbers for the Master and Godlike motherboards. voltage spikes at 1.45 V or higher are absolutely normal with a 3900X. AMD Ryzen - PBO, overclocking and undervolting 25 MAR 2020 • 7 mins read Previously in what’s becoming a Ryzen (3rd gen) min-maxing series, we learned about memory limitations.This time around I’d like to introduce you to three different things that you can do with the clock and voltage. Single-threaded testing pushed them closer together, with all the results landing in the 1.47-1.49V range. The average core VID numbers stack up differently than the reported vcore. So with the profile you want to set up selected, click the “FIVR” button in Throttlestop. 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”! At the very least, this proves that the BIOS option is doing something, even if the end result isn’t what we want. Next, we decrease the “Offset Voltage” slider, which is the undervolting part. Re: Max safe voltage for 3900x overclocking? My default process is undervolting via my BIOS’ offset mode and reducing the voltage step by step.

The reason why we’re interested in max values instead of so… 3900x and Asus C8H. Even though the original content was too good to be true, it was still based on a completely valid idea -- lowering voltage, 50% of the equation for power -- will theoretically reduce thermals and power load. 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. I also see 4.350MHz to 4.375MHz while gaming instead of 4.300MHz with auto vcore offset. 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. 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. In POV-Ray, running the 3900X at a flat 4.3GHz at 1.35V gives it a 8.2% performance boost over stock. "3900x is running a bit hot and high voltage, but I figure that will get fixed with a motherboard update." I managed to overclock my 3900X to 4.3GHz across all cores – a big improvement from the 3.9GHz I achieved out of the box, but still a little short of AMDs claimed 4.6GHz. GamersNexus.net is Owned, Operated, & Maintained by GamersNexus, LLC. Does it work for you? The most interesting part of these results, however, are the scores with a negative voltage offset: the Godlike board was stable with an offset as low as -0.1V using the 3900X, and gained 2% over the stock multithreaded score. At least that was how my 2700x performed. To test for the clock stretching I just use Cinebench r20. This first one shows the R5 3600 on the Godlike at 1V, stock, and at -0.05v offset. I have a 3900x with the stock cooler and a gigabyte x570 UD motherboard. 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. I am getting about 4566.6 max. So.. Lower voltage means, lower temps on … 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’s the 3600 set to 1V that requests the highest voltages during the multithreaded test, at about 1.4V versus 1.36-1.37V stock and offset. 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. August 15, 2020. 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. Experience any stability or clock stretching stretch rather than crash when power.!
