AMD's figured out why Ryzen CPUs were burning up, BIOS fix already rolling out
AMD has confirmed an issue that saw some users Ryzen 7000-series CPUs burn out(opens in new tab), and says a fix is on the way from its motherboard partners in the «next few days,» if it's not already available.
«We have root caused the issue and have already distributed a new AGESA that puts measures in place on certain power rails on AM5 motherboards to prevent the CPU from operating beyond its specification limits, including a cap on SOC voltage at 1.3V,» the statement from AMD says.
«None of these changes affect the ability of our Ryzen 7000 Series processors to overclock memory using EXPO or XMP kits or boost performance using PBO technology.»
That last bit is crucial, as the issue had previously been linked in a statement from Asus to EXPO memory profiles. These memory profiles allow for easy overclocking of memory kits to their advertised speeds, and require an increase to SoC voltage in order to run sufficiently stable. It's this SoC voltage that is likely the cause of the issues some users have since reported, including the damage seen to user Speedrookie's CPU, as seen in the picture posted to Reddit(opens in new tab) below.
While EXPO memory profiles are considered overclocking, and thus are not covered by any warranty, AMD has said that any user affected by the issue should get in touch with its customer support.
«Our customer service team is aware of the situation and prioritizing these cases,» AMD says.
That hopefully means any affected chips will be replaced without the user having to fork out to replace the poorly parts.
