Asus PRIME B760M-F D4-CSM

Launch Stability & Compatibility

The initial firmware release v0401 establishes the baseline operational parameters for the B760 platform. Subsequent update v0402 integrates Microcode 0x123, which serves as a preliminary mitigation for Raptor Lake instability by correcting early eTVB algorithm errors, while also introducing the ability to disable CEP (Current Excursion Protection) to enhance performance on 14th Gen processors. This configuration is further tuned in v1646 to optimize voltage regulation when CEP is disabled, ensuring consistent power delivery during high-load scenarios.

Feature Maturity & Hardware Support

Mid-cycle updates focus on aligning system performance with manufacturer specifications. Version 1656 introduces the Intel Baseline Profile, allowing users to revert to factory power limits to resolve stability issues in gaming workloads. This feature set expands in v1659, which establishes distinct "Performance Preferences" for Intel Default Settings versus ASUS Advanced OC profiles and redefines factory defaults to prioritize stability. Additionally, v1661 integrates Microcode 0x125, patching a critical bug in the eTVB algorithm that previously allowed processors to boost frequencies beyond safe thermal thresholds.

Critical Security & Power Management

Later firmware revisions prioritize long-term processor health and security. Version 1663 implements Microcode 0x129, applying a hard voltage clamp to restrict maximum VID requests to 1.55V. The mitigation strategy for Vmin Shift Instability advances in v1666 and v1805 with Microcode 0x12B, which addresses elevated voltage requests during idle states and enforces C1E power states to reduce processor stress. Update v1820 further strengthens this protection via Microcode 0x12F, targeting edge-case voltage drifts and "Always On" degradation risks. Finally, v1825 consolidates general security patches and updates the Management Engine to version 16.1.35.2557.
