You mean the schematic is not correct Motherboard NM-B453 ?
Same NM-B453 but difference parts number, example on IC like AWV7B on 320-15ikb v1.0 but your post is 330-15ikb v0.1 PDF file is AWV5B ic name but on datasheet is difference output.

Please help if you have exact board schematict on 320-15ikb V1.0
