Just a question to everyone out there, what is the maximum safe Vcore for Ryzen 3000? I am now manually overclocking, and I currently have my 3800X at 1.38V 4.4Ghz all core, however I have achieved a stable 4.45Ghz all core overclock but need ~1.44V. I know that the max safe Vcore for Ryzen+ was 1.45Ghz for all core manual overclocking, but I don't know what the max is for the new Ryzen 3000.

I have just finished stability testing and running benchmarks. This is manual overclocking 4.4Ghz @ 1.38V.

Exatly im in a custom water loop whit dual 240 rad and on stock reach 75/80 C .... if im oc 4.2 all core max i see is like 65 on prime 95 large ftt ... unbelivable

Been manually overclocking, stability testing, and bench marking my 3800X all day. I have found something interesting. I can run my 3800X totally stable 4.4Ghz all core @ 1.3V, it will pass every stability test I can throw at it and appears 100% stable. However if I increase the Vcore to 1.38V with the same 4.4Ghz overclock I get on average a 3% performance bump in benchmarks. My Ryzen 2700X would perform the same at any voltage over where it was stable, however the extra bump in Vcore has a much greater effect than would make sense. I guess it could be my particular motherboard, or maybe just how the Strix X470-F delivers power but just thought I would throw it out there.


With that said, I have also tweaked my max overclock of 4.5Ghz all core @ 1.44V. I would just like to ask if anyone knows what the max Vcore of the Ryzen 3000 series is, as I can't seem to find the information anywhere. I am nervous about running 4.5Ghz @ 1.44V for a 24/7 overclock until I know how much voltage is considered "safe" for Ryzen 3000. My temps are fine with the 4.5Ghz overclock as this chip seems to be very cool running and under "normal" use rendering, benchmarks, gaming, ect I haven't seen temps above 73C and on the stability tests I maxed out at 81C- both well within the temp max of 95C.


Until I find out the max Vcore for the Ryzen 3000 series I'm keeping my 4.4Ghz @ 1.38V and am going to start working on pushing my RAM overclock.

Officially, nobody knows. AMD isn't talking. I'm sure you've heard people talk about limits before, or if you haven't . . .

https://www.overclock.net/forum/10-a...ot-really.html

Apparently 1.325v for high-current loads, and 1.47v for low-current loads (basically single-threaded stuff). However that's straight from the FIT tables of one 3900x CPU. Your 3800x may have different limits. 1.44v might not be the best idea for something that's really stressing your CPU. And definitely watch it with the voltage when running AVX2-heavy workloads like Prime95 SmallFFTs or (worse) certain PrimeGrid workloads.

Watch this space for future . . . uh . . . stuff! Yeah. That.

Thank you for the reply. I have seen the 1.325V limit thrown around here and there, but didn't realize it was related to the 3900X. It would be nice if AMD were to release the Vcore limit, and they always use to... I think for now I will stick with my 4.4Ghz overclock @ 1.38V. It isn't that much more voltage and hopefully will be fine.

Ok, I have a couple other questions that hopefully some of the experts here have run into. First of all with Ryzen+ I used Ryzen Master quite frequently but ever since upgrading to the 3800X Ryzen Master is totally broken. I had problems trying to uninstall it, and after finally getting it to uninstall I can't get the newest version to install. Every time I download the latest version and try to run it I get an error telling me a more recent version of the program is already installed, but its not... Do you need Ryzen Master for CCX overclocking?



Second has anyone had any success in using an offset voltage when manually overclocking Ryzen 3000? I have a positive offset voltage set right now, and under full stress I am now running at 1.37V and now my temps have also improved by about 2C. I have noticed that now HWinfo64 will no longer give me the proper Vcore readings, however both HWMonitor and CPU-Z show the voltage scaling down when the processor is at rest and they are both showing the same voltage. Has anyone else noticed issues with various monitoring applications? I would love to check what the voltage is reading in Ryzen Master, but can't get it to install.

What is your single core score with manual OCs? My BCLK 102.2 3700x does around 208-210
