TechSpot is about to have fun its twenty fifth anniversary. TechSpot means tech evaluation and recommendation you can belief.
In transient: An obvious bug has been found within the motherboard administration software from a number of main board distributors that makes it extremely straightforward to fry your X3D-based AMD CPU. We don’t but have a timetable for when safeguards shall be put in so till then, be very cautious when tinkering round in motherboard administration software with these chips. One mistake and poof, your CPU may develop into a shiny desk decoration.
Igor’s Lab not too long ago stumbled upon the problem whereas tinkering round in MSI Center. Using an MSI B550 Unify board with an AMD Ryzen 7 5800X3D processor, Igor seen the software was seemingly detecting the chip as an ordinary Ryzen 5xxx, which doesn’t have 3D vertically stacked L3 cache.
The further cache is understood to spice up gaming efficiency however its bodily presence additionally negatively impacts warmth dissipation, which is one purpose why it ships with slower clock speeds than the usual 5800X.
With the software unable to detect an X3D chip, it treats it like an ordinary Ryzen 5xxx and permits largely unfettered manipulation of the core multiplier and core voltage. Intrigued, Igor fiddled with the voltage settings and managed to kill the CPU briefly order. He didn’t point out how a lot juice was fed to the chip to take its life however Tom’s Hardware notes that core voltage can be set all the best way as much as 1.55v.
Worse but, the obvious bug has since been found in related administration software from ASRock, Asus and Gigabyte.
Just final week, famend overclocker der8auer tried his hand at overclocking and overvolting the AMD Ryzen 7950X3D. Even with liquid nitrogen, the chip immediately died when the core voltage was set to 1.55v. der8auer barely made it out of the BIOS (and with none important load) earlier than issues went south. Needless to say, he was shocked it died so shortly.
At the very least, it appears like these excessive core voltage choices ought to carry a agency warning earlier than customers are allowed to use dangerous settings.
