Medion B460H6-EM BIOS update is primarily used to address stability issues or security vulnerabilities like LogoFAIL. However, users frequently report that updates do not unlock advanced features like XMP profiles or manual RAM overclocking, which are often restricted by the motherboard's firmware. Latest Version & Availability
Latest Known Version: V1.07 (specifically 460H6W0X.107) is the most recent reported stable version.
Where to Download: Official updates are typically found on the Medion Service Portal by searching for your PC's specific MSN number. If it is not listed, check the Medion Community forums where support staff occasionally provide direct links. Update Procedure
The B460H6-EM update is often performed directly within Windows using a batch script:

Completion: The PC will shut down or restart automatically. Wait 1–2 minutes for the process to complete before attempting to use the system again. Known Limitations
RAM Speeds: Even after updating to V1.07, the board generally lacks XMP support. High-speed RAM (e.g., 3200MHz) will often downclock to 2133MHz or 2666MHz because the board does not supply the required 1.35V for XMP.
Hardware Compatibility: Some users have reported issues with high-end PCIe 4.0 NVMe SSDs (like the Samsung 990 Pro) not being recognized initially in the BIOS settings.
Resizable BAR: This feature is typically not supported or enabled on this motherboard, even with BIOS updates.

The hum of the server room was a low, rhythmic pulse, a digital heartbeat that Elias had grown to ignore. But today, the silence between the pulses felt heavy. In front of him sat the Medion B460H6-EM
, a motherboard salvaged from an Erazer gaming rig, now destined for a budget workstation build. It was a sturdy piece of tech, but it was stubborn. It refused to recognize the newer NVMe drive he’d slotted in, a clear sign that the was trapped in the past.
Elias pulled up the Medion support portal, his screen glowing in the dim room. Tracking down firmware for OEM boards was always a scavenger hunt. He navigated through a maze of German-language forums and archived driver pages, searching for a version beyond the factory standard. He knew the risks: a flicker of power or a corrupted file, and the board would become a high-tech paperweight.
He found it—a .zip file tucked away in a sub-directory. He formatted a small USB drive to Step 3: Preparation and Safety Updating a BIOS
, moved the update files over with a surgeon’s precision, and rebooted the machine.
Entering the BIOS felt like stepping into an old library. He navigated to the flash utility, selected the file, and held his breath. “Processing... Do not power off.”
The progress bar crawled forward. 20%... 50%... 85%. In those seconds, Elias thought about the thousands of gates and circuits being rewritten. Finally, the screen went black. The fans spun up to a roar, then settled. The Medion logo splashed across the screen, now accompanied by a updated version string in the bottom corner.
He checked the storage settings. There it was: the NVMe drive, fully recognized and ready for duty. The "Frankenstein" build was officially alive. for this update or troubleshooting common errors for this specific board?
Updating a BIOS carries a risk of hardware failure if the process is interrupted.
| Update if... | Skip if... | |--------------|-------------| | You have CPU instability or RAM issues | Everything works fine | | Medion support explicitly recommends for your service tag | You use proprietary fan control (may break) | | You need Resizable BAR or newer microcode | You can’t afford downtime (small risk of brick) |
Medion typically provides two methods:
Once the flash reaches 100% and your PC reboots:
