What steps are needed to adjust the CPU voltage settings in the BIOS of an Asus motherboard for a Ryzen 3000 processor?
This could be a simple mistake, but I'm experiencing some problems with the BIOS regarding CPU voltage adjustments. I change the VDDR setting to manual, but I'm unsure how to set the exact voltage level. I click the option, nothing happens, and then it reverts to auto mode. The default voltage is too high at around 1.5v, so I need to reduce it. My motherboard is an Asus Tuf gaming X570 plus with Wi-Fi, and the CPU is a Ryzen 3700x.
Did you check the article I shared? The actions AMD's Robert Halleck outlines are essentially the same. His take on 'what's a safe voltage' remains steady: keep it in AUTO mode, and during operation it reaches up to 1.5V, while under heavier loads it stays between 1.2 and 1.3 volts. And it can fall as low as 0.6V when in sleep states (which is quite common, even amid...
i have identical boards but only the cpu differs... adjusting the offset voltage to -0.1 resolves the issue... that should be visible under vddr cpu voltage settings.
The reasoning comes from AMD's statement about the voltage increasing to 1.5V during boosting, which they claim supports their position.
Not the complete picture. That 1.5v setting applies only to single-core use; with multiple cores it's better to keep the CPU below 1.26v at boost for any duration. Early developers discovered this issue firsthand during initial optimization attempts, when CPUs would fail within six months under steady voltages between 1.35v and 1.4v.
Did you check out the article I shared? The actions AMD's Robert Halleck outlines are essentially the same. His take on 'what's a safe voltage' remains largely unchanged: keep it in AUTO mode, and during operation it typically reaches up to 1.5V, with fluctuations between 1.2 and 1.3 volts under heavier loads. Furthermore, it can fall as low as 0.6V when in sleep modes—something quite remarkable, especially given the intense workloads.
Additionally, stating that '1.5V is single core only' isn't entirely accurate. Ryzen doesn't apply different voltages based on core count; instead, it boosts a single core only during lightly threaded tasks to as high as its maximum boost frequency, potentially reaching up to 1.5V. When the voltage increases, all cores will experience it. Early overclockers like TheStilt mentioned that Ryzen lacks functional LVDRs on the die, which would allow for lower voltages from the single VCore output. I haven't seen any suggestions suggesting this change, though there were some discussions about possible differences in Threadripper.
It's regrettable but we must accept small pieces of useful information like the one provided by Robert Halleck. What little enthusiasts such as TheStilt, Buildzoid, 1Usmus, and Der8auer can glean from CPU analyses, BIOS updates, and leaked engineering details is limited. It appears that anyone obtaining valuable insights from AMD often faces NDAs, which has been a point raised by Buildzoid—he mentioned he could request more data from AMD but would need to sign an NDA, potentially preventing him from sharing findings openly due to concerns about violating the agreement. AMD should consider being more open and sharing more information with hobbyists and DIY communities so we don't all remain in the dark. This situation leads OP to believe he truly needs to reduce voltage when it naturally rises to 1.5V during boost phases.
I comprehend the NDA requirements. AMD has been striving to compete with Intel for years, dealing with frivolous lawsuits and Intel's pressure on game developers. They finally secure a pause and can proceed without issues, while Ryzens maintains efficient core counts, handles temperatures and voltages well, and avoids large motherboard parts or power supplies—all using 7nm technology when Intel is still working to streamline the 10nm process.
They are not sharing information because they wish to limit Intel's access to more detailed specifics, particularly since Ryzens is not fully completed.
I realize it might still be important, even though I can’t see the exact details. The issue is that Ryzen behaves quite differently compared to Intel’s boost algorithms, especially from the first generation onward. Many still believe higher voltages are harmful. It’s hard for AMD to clearly explain why their up to 1.5V spikes aren’t problematic—perhaps due to electron movement or the processor’s boosting process during heavy multithreaded tasks. The Buildzoid videos on his YouTube channel are really helpful in this regard, though it’s unclear if he would have shared them under an NDA. I think AMD’s cautious approach makes it difficult to convey the message effectively.
