AMD Ryzen 7000X3D voltage warning

Ryzen 7000X3D Might Be Restricted to 1.35V After Der8auer’s CPU Disaster

Posted on

Well-known overclocker der8auer visited Asus HQ this week and killed a shiny new AMD Ryzen 7000X3D with alarming ease. The 3D V-Cache enhanced Ryzen 9 7950X3D didn’t final lengthy in overclocking assessments, after tweaked voltages and lashings of liquid nitrogen cooling had been utilized. Nonetheless, the premature demise of this CPU will finally save others, as Asus / AMD will “most likely” implement a 1.35V ceiling on X3D processors in upcoming motherboard BIOS updates.

Der8auer  is presently documenting a visit to Taiwan through YouTube. After quaffing a pint of the native bubble tea, he headed to Asus HQ for some pc testing and overclocking enjoyable. The TechTuber defined it had been round seven years since his final go to to the tech treasure island, primarily due to the Covid-19 pandemic and journey restrictions.

After a number of days of Intel Sapphire Rapids testing, Der8auer was provided the chance to check the most recent AMD Ryzen 7000X3D processors at Asus’ well-equipped labs. The knowledgeable overclocker had a sense that there could possibly be a “nice danger” in enterprise such an endeavor, as a consequence of AMD’s warnings and locking down of the earlier gen X3D elements (AMD Ryzen 5000X3D processors). Nonetheless, with the most recent gen, AMD has relaxed issues just a little, permitting extra tweakability for individuals who prefer to dabble.

Utilizing a Ryzen 9 7950X3D and Asus ROG Crosshair X670E Excessive, der8auer started his investigations into efficiency and energy. At first of this part of the video, the overclocker says that the CPU sometimes ran at 1V, however the Crosshair motherboard allowed him to pump up the voltage to 1.35V, as a modest however worthwhile first step in LN2-fuelled overclocking. The noticed temperatures of <90°C with liquid nitrogen cooling had been comfortably close to to what can be anticipated at inventory voltages utilizing an AiO liquid cooler.

Inspired by the success of the overvolting and stability of the system, der8auer selected a subsequent step of 1.55V. He defined that this sort of voltage was a big ramp up from inventory, however can be a typical subsequent step in exploring the capabilities of a contemporary Intel CPU or AMD CPU with out 3D V-Cache.

Upon restart, proper after the BIOS display flew previous, the open bench testing system fell flat, with the motherboard exhibiting an ominous 00 error code. The standard technique of error restoration didn’t revive this technique, and subsequent investigations revealed that the CPU was stone lifeless. Der8auer’s video voiceover asserts that the demise of the CPU was fully surprising, particularly because it solely managed to run previous the BIOS display, and no testing or computational load was exerted utilizing the brand new voltage.

The YouTuber didn’t need to draw conclusions about secure voltages for the Ryzen 7000X3D collection primarily based on a pattern of 1, however reported again to Asus, who will most likely restrict the max guide selectable voltage for X3D chips to 1.35V. He surmised that the voltage being so configurable, and choices as much as 2.5V being out there, was most likely an oversight by AMD motherboard companions and wanted to be fastened.
