ASRock Launches BIOS v3.40 for 800-Series Motherboards, Improving CPU Stability and Memory Compatibility for AMD Ryzen Processors

ASRock has recently launched an updated BIOS version aimed at enhancing the performance and stability of both CPU and memory systems. This upgrade is particularly significant as it aims to address issues related to the burning of Ryzen 9000 CPUs on ASRock motherboards.

ASRock 800-Series Motherboards Unveil New BIOS 3.40 for Improved System Stability

In its latest development, ASRock announced the release of a new BIOS version, 3.40, specifically for a selection of its 800-series motherboards. According to information on the official support pages for several B850 and X870 models, this update is designed to improve memory compatibility and stabilize CPU operations. These enhancements are particularly crucial for users of Ryzen 9000 series CPUs, who have been disproportionately affected by failures associated with ASRock motherboards.

BIOS update options with version 3.40 include improve memory compatibility and system stability and enhance CPU operating stability.

While the precise modifications included in BIOS version 3.40 remain undisclosed, it is anticipated that they align with AMD’s guidelines for the Ryzen 7000 and 9000 series CPUs. AMD has previously suggested that non-compliance of ODM BIOS has contributed to the failure of Ryzen 9800X3D and 9000 series CPUs, urging users to update their motherboard BIOSes. However, even those who have followed this advice have reported instances of burned CPUs while using ASRock boards.

Although reports of burnt CPUs have emerged across various motherboard brands, ASRock motherboards have garnered the most significant attention as the primary issue. Despite ASRock’s ongoing effort to release updated BIOS versions over recent months, the incidents of burnt CPUs have not entirely ceased. The recent BIOS 3.40 promises notable enhancements to CPU stability. Earlier BIOS updates focused on improving various CPU functionalities, including boot issues and Precision Boost Overdrive (PBO), but could not fully eradicate burning issues.

Regarding the enhancements in BIOS version 3.40, one user revealed changes in the Voltage Scale Optimization Control (VSOC) behavior. The Load-Line Calibration (LLC) for System-on-Chip (SOC) has been adjusted to a fixed Level 3 setting, previously set to Auto. Additionally, the VDDCR_SOC voltage is now maintained at a steady 1.2V in “Fixed Mode.”This modification is expected to significantly reduce the likelihood of voltage-induced damage and CPU degradation.
