Well-known overclocker der8auer visited Asus HQ this week and killed a sparkly new AMD Ryzen 7000X3D with alarming ease. The three-D V-Cache enhanced Ryzen 9 7950X3D didn’t closing lengthy in overclocking assessments, after tweaked voltages and lashings of liquid nitrogen cooling have been carried out. On the other hand, the premature dying of this CPU will in the end save others, as Asus / AMD will “almost certainly” put in force a 1.35V ceiling on X3D processors in upcoming motherboard BIOS updates.
Der8auer is these days documenting a travel to Taiwan by means of YouTube. After quaffing a pint of the native bubble tea, he headed to Asus HQ for some pc trying out and overclocking amusing. The TechTuber defined it have been round seven years since his closing discuss with to the tech treasure island, principally as a result of the Covid-19 pandemic and trip restrictions.
After a number of days of Intel Sapphire Rapids trying out, Der8auer was once presented the chance to check the most recent AMD Ryzen 7000X3D processors at Asus’ well-equipped labs. The professional overclocker had a sense that there can be a “nice chance” in endeavor such an undertaking, because of AMD’s warnings and locking down of the former gen X3D portions (AMD Ryzen 5000X3D processors). On the other hand, with the most recent gen, AMD has comfortable issues a bit, permitting extra tweakability for individuals who love to dabble.
The use of a Ryzen 9 7950X3D and Asus ROG Crosshair X670E Excessive, der8auer started his investigations into efficiency and gear. At first of this phase of the video, the overclocker says that the CPU normally ran at 1V, however the Crosshair motherboard allowed him to pump up the voltage to at least one.35V, as a modest however profitable first step in LN2-fuelled overclocking. The noticed temperatures of <90°C with liquid nitrogen cooling have been conveniently as regards to what can be anticipated at inventory voltages the use of an AiO liquid cooler.
Inspired by means of the good fortune of the overvolting and balance of the gadget, der8auer determined on a subsequent step of one.55V. He defined that this sort of voltage was once an important ramp up from inventory, however can be a normal subsequent step in exploring the features of a contemporary Intel CPU or AMD CPU with out three-D V-Cache.
Upon restart, proper after the BIOS display flew previous, the open bench trying out gadget fell flat, with the motherboard appearing an ominous 00 error code. The standard method of error restoration didn’t revive the program, and next investigations printed that the CPU was once stone useless. Der8auer’s video voiceover asserts that the loss of life of the CPU was once solely surprising, particularly because it most effective controlled to run previous the BIOS display, and no trying out or computational load was once exerted the use of the brand new voltage.
The YouTuber didn’t need to draw conclusions about secure voltages for the Ryzen 7000X3D sequence in accordance with a pattern of 1, however reported again to Asus, who will almost certainly prohibit the max guide selectable voltage for X3D chips to at least one.35V. He surmised that the voltage being so configurable, and choices as much as 2.5V being to be had, was once almost certainly an oversight by means of AMD motherboard companions and had to be mounted.
Somewhere else in der8auer’s video, you’ll watch some Sapphire Rapids OC amusing, take a look at some overclocking {hardware} prototypes, and extra. The 35-minute video is easily value an eye. You’ll be able to benefit from the complete video above.
