This is a quick and straightforward piece inspired by a Reddit post from about a week ago. 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. Copyright © 2021 GamersNexus, LLC. 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 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. 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 . The clocks will appear normal or improved even though performance is reduced. The Division 2 Performance Review: Ubisoft Finally Makes DX12 Shine. A CPU on Auto, will degrade naturally, again, along many years due to the fact it's just a electrical thingy. Put PBO on "Enhanced Mode 4" with a CPU voltage on offset mode of -0.1v. 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. As long as you stay under 1.45v and 90*C you're fine for long term use. Limit your EDC to 140 as well. Do you agree? Scored higher CB 20 in MT bench and CPU-Z bench mode. There will be some delay after submitting a comment. 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. Voltage offset is your friend. YMMV because of silicon and cooling differences. Like way too high. 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). 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. Much like GPU overclocking must be validated with performance tests, CPU volt-frequency changes have to be validated with performance. Lower temps and better benchmark scores. I recommend a Small undervolt for a little performance. Launch hwinfo64 and monitor the boost clocks. I posted mine. It seems that Auto means off. Mein Wert liegt bei 4866. voltage spikes at 1.45 V or higher are absolutely normal with a 3900X. It’s not a huge leap, but it’s a real improvement and the same behavior was shown on the X570 Master. 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 I run with a fairly high -0.120 undervolt offset but even with that I don't experience any stability or clock stretching. 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. Using a slight negative offset voltage with low LLC as @coercitiv suggested earlier should also work with the temp limit. So let's see some actual real measurements. Ryzen 3900X voltage Hello, I recently acquired a 3900x CPU and I am experiencing several cases that I do not know if they would be normal. Keep doing increasing the offset and running the tests until your score decreases. Latest AMD drivers with AMD balance profile. SoC voltage, VDDP voltage & more. R9-3900X | GA-X570 Aorus Xtreme | 32GB 3600MHz CL17 | GTX 1070 | Samsung 970 Evo Plus Sabaj D3 | Superlux HD668B. All rights reserved. Run an r20 test and record the score again. To paraphrase Reddit user Boxman90’s response post, lowering vcore a little bit without being in OC mode (locking the clocks, etc.) 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. It prevents the CPU from getting hotter allowing to boost faster. Had some issues with mine id like to help with if they are similar and save you some time. 3. In POV-Ray, running the 3900X at a flat 4.3GHz at 1.35V gives it a 8.2% performance boost over stock. 0 Kudos Share. It didn’t on the 3600, but the 3900X was a different story. 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. Edit: specs Ryzen 3900x Cooler master 212 evo Aorus ultra 1.x mobo Aorus 2080 super waterforce Corsair 32g (16x2) 3200MHz 1TB samsung evo nvme m.2 4 nzxt case fans+ the rad and 2 fans from GPU. Temps lowered drastically in high load. I run with a fairly high -0.120 undervolt offset but even with that I don't experience any stability or clock stretching. We used a +0.4v VCCSA offset to get the memory that high and a 1.5v DRAM voltage. I am receiving my 3900x in a few days. 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. "3900x is running a bit hot and high voltage, but I figure that will get fixed with a motherboard update." Using a slight negative offset voltage with low LLC as @coercitiv suggested earlier should also work with the temp limit. Here’s our first two charts, we’ll just take turns putting them on the screen. Ideally though you should aim for no more than 1.4v and 80*C. Now enjoy lower temps and better performance : ), you forgot to test other avx workloads, blender, Occt or Prime might trigger a different avx clock and that -120mv is enough to crash/reboot the system, -120mv is no big deal uder normal avx, but heavy avx drop your voltage to 1.15-1.2 and -120mv there is too much. In the new window, tick the “Unlock Adjustable Voltage” box. The reason why we’re interested in max values instead of so… 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. 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. 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”! Ist das Normal für einen Ryzen 3 3900X mit einer 240er AiO? Beiträge 28. We’ve also zoomed the frequency charts to a 2000MHz range in order to make the differences more obvious. Editorial, Testing: Patrick LathanHost: Steve BurkeVideo: Andrew Coleman. As mentioned in other threads I’m currently trying to undervolt my 2700X. Για overclockιng** χωρίς υδρόψυξη ξεχάστε το. So.. Lower voltage means, lower temps on … 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. The system boots fine and doesn’t show any signs of instability, but on both motherboards there was a very real decrease in performance. For our final charts, we’ve stuck results from both boards together, because the point is simple: Tdie is vastly lower on both the R5 3600 and the 3900X with vcore set to 1V, and as the previous charts have shown clocks are higher, but that doesn’t mean performance is better. 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 . The next chart shows the same type of data, except on the R9 3900X instead. I idle at 30 to 35 with the occasional small spike into the high 40s. Under heavy load the 3900X can run at 1.1v with vdrop which is a great CPU. I've noticed large benefits with this on pbo and auto oc and it's not the power bug. 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. 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. 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. It benefits this cooler and the stock cooler far more. The ability of the generator(s) to react to the fault and time necessary to stabilize the system. This actually only dropped benchmark scores by less than 5%, but didn't change the CPU temps by any noticeable amount. 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 . Typically the CPU starts downclocking due to thermals. 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. I cant remember the voltages i am set at, but it is low like.. 1.1x. I haven't build it yet. 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. PBO enabled. Running PBO with +200mhz, scaler at x10, rest auto and just the positive offset. Does it work for you? 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. … 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 … With clocks set on auto the CPU will clock stretch rather than crash when power starved. Ok just done some more testing. It’s clear that the 1V vcore result isn’t actually performing better on either CPU, though, simply by a rough comparison of how much longer the test took to complete. With the 3900X chart, there’s a more clear division during the multithreaded test with stock the lowest (1.23V), then the offset (1.32V), then the 1V results (1.34-1.35V). Increasing GFX voltage to 1.3V did nothing, and did not change the voltage readings at all. R9 3900X - 4.1-4.2 when most or all cores in use. We ran the 3600 and the 3900X each both on the Gigabyte X570 Master and the MSI X570 Godlike, running Cinebench R20 three times multithreaded and then once single threaded while logging in HWiNFO and recorded the scores. GamersNexus.net is Owned, Operated, & Maintained by GamersNexus, LLC. But also, I have seen recommendations of - 0.05 offsets. To test for the clock stretching I just use Cinebench r20. These charts show VID instead. On the R9 3900X, clocks were less constant, but it still reported holding higher clocks than stock with 4225MHz during the multithreaded tests. The average core VID numbers stack up differently than the reported vcore. Moving into the single-threaded test has the offset results averaging the highest VID. New comments cannot be posted and votes cannot be cast. 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 1.0.0.3 AB CPU VID (BIOS) I don't trust any of the programs readings. 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. For me the offset was the best thing I have done to boost performance and reduce temps. These next charts are all frequency plots. Since Silicon Lottery tests AVX2 loads, the CPU max frequency will be rated for practically the worst-case scenario. Not sure if that is their marketing tactic but is pretty simple. 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. My single core score in cinebench went up after it and I see single core boost at 4400-4500+ depending on load. So how far can I take the positive offset and whats the max safe voltage and temperature for long term use?
