merely put: An obvious bug has been discovered within the motherboard administration software program of a number of main motherboard distributors, making X3D-based AMD CPUs extraordinarily susceptible to blowing up. We haven’t got a timetable but for when protections can be put in, so till then, be very cautious about modifying motherboard administration software program with these chips. One misstep and your CPU could possibly be remodeled right into a shiny desktop decoration.
Igor’s lab stumbled throughout this problem whereas tinkering in MSI Central lately. Using an MSI B550 Unify motherboard with an AMD Ryzen 7 5800X3D processor, Igor seen that the software program appeared to detect the chip as a typical Ryzen 5xxx, which doesn’t have the 3D vertically stacked L3 cache.
Extra cache is understood to enhance gaming efficiency, however its bodily presence additionally negatively impacts cooling, which is without doubt one of the causes it clocks slower than the usual 5800X.
Since the software program can not detect the X3D chip, it treats it as a typical Ryzen 5xxx and permits largely unrestricted manipulation of the core multiplier and core voltage. Out of curiosity, Igor fiddled with the voltage settings and managed to kill the CPU for a short while. He does not point out how a lot juice was injected into the chip to finish its life, however Tom’s Hardware notes that the core voltage could be set all the best way as much as 1.55v.
Worse, this obvious bug has been present in comparable administration software program from ASRock, Asus, and Gigabyte.
Just final week, well-known overclocker der8auer tried to overclock and overvoltage the AMD Ryzen 7950X3D. Even with liquid nitrogen, the chip dies immediately when the core voltage is about to 1.55v. der8auer barely exits from the BIOS (and with none important load), after which issues go unhealthy. Needless to say, he was shocked it died so shortly.
At least, it appears like these excessive Vcore choices ought to sound a agency warning earlier than permitting customers to use harmful settings.
