My Asrock Conroe865PE board does not seem to work with this mod, after downgrading the BIOS to v1.40 (which does not officially support E4300), the board boots up at 266MHz FSB, even in the bios the auto setting shows 266MHz, so the board must be ignoring the FSB pin signals, mod was removed to verify this.
