UPDATE
Leaving my original findings in first post, SOLVED by performing these adfvanced steps
1 Roll back to (1511 TH2) EDITION
2 Install Asus REALBENCH , you can run the benh if you want, on 1511 the notebook is solid as new, RUN ASUS CpuZ, Confirm MARS codename ....
Mars was something i thought was mis-information by Microsoft not reading the hardware all the way correct, but in fact what it was seeing was the original hardware , not the actual Radeon R330 ReBrand
So, install all updated drivers do usual reboots, But uninstall ALL metro Apps, i knopw that sounds crazy, but on 1511 you can pack-up all the metro apps before upgrading and then reset/unpack them AFTER the upgrade and then update them if you like ....
UPGRADE TO 1703 USING THE NEW DOWNLOADED UPGRADE ADVISOR, What happens is it ends up getting hid on the C: Drive , find it located on the root of the C: drive in a folder named
Windows10Upgrade with the app named Windows10UpgraderApp
The key is the hardware runs apps and drivers it can run, make sure your Reading Mars on the CpuZ on **1703** , if not you can try to proceed with the driver upgrade
3 Now head to your dedicated CrossFireX GPU listed in Device Manager , everything looks installed / upgraded correctly with Crimson 16.4 loading but have the Vid_Hardware ATI error popping up Pre_LEaking all ver your problem Reports...
Double Click the R350DX, Upgrade Driver,
Select Driver From List, un-tick Show compatible drivers
4 Install R330
DONT REBOOT
5 Select and Install M8600 HD Video Driver
Check to make sure your driver reconfigured in the Reliability Report located in the control Panel Maintenance
Check Crimson after reboot should say
