New DDR5 Refresh Modes on AM5 Motherboards

Why It Matters

System builders and enthusiasts must verify EXPO/XMP TRFC settings or update BIOS/AGESA to avoid boot failures and ensure optimal DDR5 performance, since AGESA-driven defaults to FGR can change stability and latency behavior. The change also alters memory performance tuning and compatibility considerations across the AM5 ecosystem.

Summary

AMD AM5 motherboards from ASUS and Gigabyte now expose a Bank Refresh Mode setting that lets users choose between legacy (all-bank) refresh, fine-granularity refresh (FGR), and a mixed mode that switches dynamically. FGR refreshes one bank per bank group instead of whole ranks, improving availability and potential performance, but it uses different TRFC timings (TRFC2 and TRFC same-bank) while ignoring TRFC1. Mixed mode also does not use TRFC1, and FGR halves the effective refresh interval per the DDR5 spec, which can break systems whose EXPO/XMP profiles lack correct TRFC2/TRFC same-bank values. Early AGESA updates defaulting to FGR have caused some kits to fail to post until BIOS/EXPO timing fixes are applied; motherboard auto-recovery works in some cases but is not guaranteed across vendors or BIOS versions.
