The new BIOS version 3.40, now available for B850 and X870 models, promises “improved memory compatibility and system stability” along with “enhanced CPU operating stability.” In plain English, ASRock is trying to keep its mobos from cooking more silicon.

AMD recently blamed ODMs for failing to follow voltage guidelines, pointing the finger at dodgy BIOS tuning rather than its own chips. The company urged users to update their firmware, though plenty of ASRock customers reported crispy 9800X3Ds even after previous updates. Among all vendors, ASRock’s boards have earned the unflattering title of being the most lethal to Ryzen 9000 silicon.

This latest patch seems to go further than earlier tweaks. One user on Reddit noted that VSOC behaviour has been altered: Load-Line Calibration for SOC is now locked to Level 3 instead of “Auto,” and VDDCR_SOC voltage is capped at 1.2V in fixed mode. By preventing the SOC rail from wandering above that threshold, the new BIOS should at least reduce the risk of slow degradation or instant barbecue.

While earlier ASRock BIOS releases dealt with niggles like boot hiccups and PBO quirks, this is the first to explicitly tout enhanced CPU stability. It’s a clear sign the vendor knows it has a problem on its hands, even if it won’t admit how many chips have already gone up in smoke.

Whether BIOS 3.40 is enough to keep the Ryzen 9000 series safe remains to be seen, but for now, ASRock users have one clear message: update or risk another burnt offering to the silicon gods.
