ASRock BIOS version 3.40, an update for AMD 800 motherboards designed to improve CPU and memory stability. Due to previous failure cases on ASRock boards with Ryzen-9000X3D CPU.
According to reports of damaged Ryzen-9000X3D processors on AM5 motherboards, Asrock is releasing BIOS version 3.40 for 800 boards (for example, on the X870 Steel Legend Wifi or B850 Pro-A Wifi), which, based on the brief description, is supposed to improve the stability of the CPU and RAM. However, Asrock does not provide more specific technical details. According to initial feedback on Reddit (for example here or here), Asrock has mainly adapted voltage options in the new BIOS: the SOC load line calibration is now set to level 3 in the user posts (instead of auto before), and with EXPO profile the VSOC voltage is fixed at 1.20 volts. The memory OC view has also been revised. The 3.40 update follows about two months after the previous version 3.30 and almost three months after the first user reports about problems with Ryzen-9000X3D processors became public on Asrock boards.
ASRock BIOS version 3.40: Ryzen-9000X3D with damage on Asrock boards
In recent weeks, reports have been circulating that Ryzen 9000X3D CPUs on Asrock motherboards have been damaged or, in extreme cases, even destroyed. Users reported burned sockets or permanently defective CPUs. Systems in which the BIOS did not exactly follow the specifications specified by AMD seemed to be particularly affected. AMD itself sees the cause not primarily in the CPUs, but above all in the deviating OC settings of some motherboard manufacturers. In an interview at the Korean Quasar Zone, AMD representatives David McAfee (CVP & GM in the client business) and Travis Kersey (Director of Product Management, also in the client area) explained that some ODM BIOS versions voltage, current or power values are not completely within AMD’s official specifications. In addition, there is the platform complexity of AM5, which with features such as PBO and extensive overclocking options brings additional risks and side effects when compiling different BIOS settings. According to AMD, they are working closely with the partners to fix the problems.
Asrock had already made adjustments at certain voltages starting with BIOS 3.25. These measures reduced the number of failures, but, similar to Intel’s Raptor Lake drama (with microcode updates), they no longer help with already permanently damaged processors. BIOS version 3.40 adjusts the adjustments even more sharply.

Update recommendation, with usual caution Ryzen-9000X3D
If you are using a corresponding AM5 system with Ryzen-9000X3D, you should consider the UEFI update suitable for your own board in order to increase stability and security, at least according to the official values. However, the following also applies: If the system is stable, it may make sense to wait for further feedback from the community in order to rule out possible new problems. AMD generally recommends that you always use the latest stable BIOS versions more latest update subscribe Pc Decode.
