Medion Em2 System Firmware: 113

Yes, in modern usage, “system firmware” and “UEFI BIOS” are synonymous. Version 113 replaces the entire BIOS ROM.

Downgrade to version <110 is not allowed (due to Secure Boot key update).
To roll back to 110–112, use BIOS recovery mode:
Ctrl+Home on startup → place older .fd file as EMB2.ROM

Several users reported that pre-113 versions had issues with DDR4 RAM running at speeds above 2400MHz. Version 113 introduces better XMP (Extreme Memory Profile) support and stability for 2666MHz and 2933MHz modules, though capped by the chipset’s maximum. Medion Em2 System Firmware 113

At its core, System Firmware 113 for the Medion Em2 serves the fundamental purpose of hardware initialization. Upon power-on, the firmware performs the Power-On Self-Test (POST), enumerates PCIe devices, initializes memory controllers, and ultimately hands control over to the bootloader. Version 113, as indicated by its numbering, is not a first-release candidate but likely a mature revision aimed at addressing specific errata found in earlier versions (e.g., 1xx series). It is expected to include updated CPU microcode, which is crucial for mitigating speculative execution vulnerabilities (such as Spectre or Meltdown) on Intel or AMD processors, and improved compatibility with NVMe drives and modern DDR memory modules.

Furthermore, the "Em2" designation suggests a specific motherboard layout and chipset configuration—likely an entry-level or mid-range Intel (e.g., H610/B660) or AMD (e.g., A520/B550) chipset. Firmware 113 would contain the ACPI (Advanced Configuration and Power Interface) tables that dictate power states (sleep, hibernation) and thermal management. An improperly tuned ACPI table leads to excessive fan noise, poor battery life (on mobile Em2 devices), or instability during sleep-wake cycles. Thus, this firmware acts as the silent orchestrator of the user’s daily reliability. Yes, in modern usage, “system firmware” and “UEFI

After update, check in UEFI shell:

smbios -t 0 | grep "Firmware Version"

Expected output: 113

Or Windows: msinfo32 → BIOS Version/Date → EMB2.113.xxxx

If your Medion EM2 system is currently running version 107 or 110, and you are using Windows 10/11 with standard components, update to 113. If your system is stable, air-gapped (not connected to the internet), or running specialized legacy software (e.g., Windows XP embedded), stay on your current version.
