Message: [QUOTE="Queen, post: 85845, member: 27"] ASUS pushed a fresh AM5 BIOS that tweaks memory rules, promises smoother Ryzen behavior, and might quietly tame recent instability complaints. New BIOS rollout basics [LIST] [*]ASUS launched an AGESA Pre1.3.0.0 firmware for AM5 boards. [*]Covers both 800-series and 600-series models. [*]Targets security hardening, speed tuning, and general stability. [*]Linked to recent Ryzen failure investigations. [/LIST] What actually changed inside [LIST] [*]ComboAM5 PI_Pre 1.3.0.0 underpins the update. [*]Memory compatibility improved for JEDEC DDR5 kits. [*]System behavior tightened under edge-case loads. [*]No clear admission fixes prior failures. [/LIST] Memory behavior shake-up [LIST] [*]ASUS introduced M_Ordering, also called Bank Refresh mode. [*]Controls how DDR5 refresh paths get enforced. [*]Default switched from Normal to Relaxed. [*]That shift can break older memory profiles. [/LIST] Why users are seeing errors [LIST] [*]Relaxed mode enforces timings that were previously ignored. [*]Aggressive tRFC values can trigger WHEA crashes. [*]Boot loops and app failures become more likely. [*]Manual retuning is basically required. [/LIST] Performance reality check [LIST] [*]Normal mode usually wins for gaming workloads. [*]Relaxed may boost synthetic bandwidth numbers. [*]Real-world gains often fail to appear. [*]Consistency beats marginal benchmarks. [/LIST] What users should do [LIST] [*]Match tRFC1 and tRFC2 values manually. [*]Test stability after every memory change. [*]Don’t expect free performance from Relaxed. [*]Stick with Normal unless a mixed refresh is needed. [/LIST] [/QUOTE]
