Message: [QUOTE="Munyaradzi Mafaro, post: 39773, member: 636"] ASRock has released a BIOS update that addresses voltage issues affecting Ryzen 9000 processors. The company adjusted hidden voltage settings and reset current limits to match AMD's official specifications. Early tests suggest that these changes should prevent the high electrical draw that damages CPUs quickly. Users need to conduct long-term stress testing across different ASRock motherboard models to confirm that the fix works properly. ASRock has not issued a public notice instructing customers to install the new BIOS version. Precision Boost Overdrive controls how processors increase speed based on temperature and power usage. Two settings, called EDC and TDC, set the maximum current levels that processors can handle safely. Original ASRock BIOS versions set these limits higher than AMD recommended for early Ryzen 9000 chips. This mistake subjected processors to dangerous electrical stress, causing them to wear out more quickly. Liquid cooling systems exacerbated the problem by maintaining low temperatures and allowing higher currents to run for longer periods. Computer users first noticed premature Ryzen 9000 failures on internet forums and traced them to ASRock motherboards. AMD refused to comment, and ASRock initially said the complaints were false. Independent technology reviewers discovered that PBO settings were configured aggressively for early processor samples. The connection between electrical current settings and failure rates forced ASRock to change its firmware approach. Questions remain about whether AMD's specifications or ASRock's interpretation were responsible for the original problems. [/QUOTE]
