Ryzen 5800X operates best with a maximum continuous voltage of around 24-7.
Ryzen 5800X operates best with a maximum continuous voltage of around 24-7.
We'll reference my current system, the Ryzen 5 2600. For the 2000 series above 1.350v it will lead to wear. Any voltage equal to or lower than 1.350v will completely prevent degradation. This applies universally to all AMD Ryzen 2000 models. Each voltage range has its own limits set by AMD. Going beyond those ranges causes issues. Staying within the allowed range avoids any problems. It's straightforward. I wasn't aware if the Ryzen 5000 series follows the same rules as the 2000 series. From what I see in the forums, it appears consistent. I've been using my R5-2600 at 1.350v and 4.2GHz all-core since August 2018, and it's functioning perfectly without any signs of wear.
I explained the proper method for it. Just to confirm, you're going to throw 1.4v at your 5800x. Enjoy! XD
I never intended to do that. From the comment above it seems I’d probably begin at 1.325v. If that doesn’t reach my goal, I’ll likely cap it at 1.350v or lower. Just to clarify: Many AMD X570 boards push between 1.40v and 1.50v through Ryzen 5000 chips by default—without any overclocking or special settings. It’s not ideal and might not be safe, but people do it without realizing. I won’t plan to run my board at those high voltages now that I understand what’s being discussed.
The XFR boost voltage consistently delivers the expected result. However, a single thread at 1.5v lacks sufficient current to surpass the thermal design power and maximum efficiency limits. This highlights that merely reporting an average voltage isn't precise. The system's Electrical Design Current (EDC) sets the boundary for performance. Raising power limits on GPUs like the RTX allows the CPU to increase its boost, pushing past the stock EDC. During manual overclocking, the EDC on Ryzen can exceed its default by more than 100%. This is when performance issues typically begin. It doesn't guarantee failure within five years, as many factors influence it. For now, it's best to keep that information private and consider the available discussions on forums regarding overheating concerns for high-performance chips. These processors are extremely fast and packed with transistors, offering twice the performance of a 2600. Expect a significantly different experience.
I've noticed those discussions and seen how some users manage to control the 5800X's heat with powerful coolers like the Noctua or a 360mm AIO. If they succeed, I'm sure my custom water loop can easily keep up with what the 5800X can deliver.
Each CPU is unique, and no fixed numbers are set for the 5000 series yet. Some chips failed after just 1.3V, so I wouldn't exceed that on Zen 2 or Zen 3—it depends on the situation.
We need a reliable method to adjust the voltage without relying on software changes each time. The current approach isn’t stable enough because performance varies across cores. I’m looking for a fixed setting that works consistently, so the system can maintain consistent speed regardless of load. The idea is to tweak the BIOS settings and let everything else handle itself automatically. This should help with the uneven boosting you’re experiencing.
I suspect you might have missed my previous message. "Curve optimizer" refers to a software tool. I can't depend on it for consistent performance. It seems AMD has finally released a chip that can't be overclocked, even though they permit it. I plan to keep everything automatic and avoid any adjustments. Everyone warns against using it at any voltage, fearing damage to the chip, so I'll let it sit. It feels disappointing to purchase an X-series chip and not be able to overclock it safely. Throughout, I've been aware there might be higher clock speeds available but can't access them due to safety concerns. I think this reflects how AMD positioned their processors. If we aim for higher clocks, they seem to encourage buying a 3950X instead of attempting overclocking now.
