HP MicroServer N40L and Gigabit HD 6450 horizontal flickering line

I recently purchased a HP MicroServer N40L and half-height Gigabit Radeon HD 6450, after installing Windows 8 I noticed that a third from the screen was a flickering white horizontal line, noticeable when playing movies in full screen or moving the mouse around the right start bar.

The problem doesn’t lie with the MicroServer of Windows 8 (or even your monitor), it is the Gigabit Radeon HD 6450 at fault here. Luckily, there is a relatively easy fix, a BIOS update.

  1. Download Easy Boost (about half way down the page)
  2. Download the Easy Boost manual
  3. Install Easy Boost
  4. Follow the “VBIOS backup” procedure, you will also find your BIOS type either F1# or F2#, mine was F21
  5. Download the correct BIOS (F11 if you have F1# or F22 if you have F2#), you can also see the BIOS offers “Fixed screen flicker problem”
  6. Follow the “Flash VBIOS” procedure.
  7. Reboot

Thanks to this RedFlagDeals post for the procedure.
