It turns out that with extreme overclocking, it’s easy to disable one of AMD’s best gaming processors, despite the experience and professionalism of an overclocker. Recently, there was one less AMD Ryzen 9 7950X3D processor in the world – after a relatively small increase in the VCore voltage, it stopped working.
German enthusiast Roman Hartung, also known as der8auer, recently visited ASUS test labs in Taiwan, where he planned to test several processors. AMD Ryzen 7000 series processors are fairly easy to overclock in Windows using PBO 2 proprietary utilities or Curve Optimizer. However, during extreme overclocking, it is preferable to use the BIOS, since it is there that the overclocker has the ability to raise the voltage up to an unrealistic 2.5 V.
Hartung began experimenting with the Ryzen 9 7950X3D, courtesy of ASUS, by overclocking with a liquid cooling system – he managed to increase the voltage on the processor to 1.35 V. For further overclocking, liquid nitrogen was required, because without it the temperature of the chip turned out to be above 90 ° C.
Hartung decided to take a chance and continued to increase the tension. The result was not long in coming – the Ryzen 9 7950X3D failed when the voltage rose to 1.5 V, after which the motherboard issued an error code 00, and the processor no longer showed signs of life, and it burned out during idle, no load. Hartung consulted with AMD and ASUS specialists, and everywhere he received a categorical answer that these chips are not designed to work with such a high VCore voltage. Roman claims that after his experiments, ASUS intends to limit the ability to increase the voltage above 1.35 V on their boards, which will be done with a motherboard BIOS update.

Hartung also got the chance to continue overclocking the $6,000 Intel Xeon w9-3495X processor, which he had previously been able to overclock at home to 4.2GHz across all 56 cores. He was confident that he could easily reach frequencies of 4.4-4.5 GHz when overclocked under LSS. It wasn’t easy, but he still managed to get further – the Xeon w9-3495X ran steadily at 4.7 GHz on all 56 cores, with only a few crashes in Cinebench R23 due to input voltage instability.
The result of 114,000 points in Cinebench R23 is impressive and demonstrates the potential of the Xeon w9-3495X with a liquid cooling system. And when the processor was cooled with liquid nitrogen, it was able to accelerate to 5.2 GHz and score 125,000 points, although it still fell short of the recently set record of 132,484 points.
