I have a 7940X on the ROG VI E with 128Gb DDR4 3333 Trident Z and one 960 Pro 1TB (with latest firmware) as a boot drive (also have 1 sata hdd and 2 sata ssds in raid 0). ROG VI E bios is up to date (1301).
I cannot upgrade to windows 1803 (nor 1709) from Windows 1703. Have used windows upgrade assistant, windows update and media creation tool. No luck. I get memory management BSOD. After two reboots it automatically goes back to 1703. I have tried cloning my nvme ssd to a sata ssd (Sandisk Extreme Pro), disabled the other drives but not luck. Same thing happened when I only had the nvme drive enabled and all other sata drives disabled. I have also tried using only Samsung nvme (latest 3.0) drivers and have tried just the Microsoft nvme drivers (uninstalled the Samsung one). No luck either. I need to avoid clean install. Must try to get the upgrade to work.
Thank you in advance
I have the 7940X slightly overclocked 4.2GH All Cores and 4.7Ghz for 2 Cores, 64GB Trident Z RGB @ 3600 XMP and a Samsung 960Pro 512GB and Windows 10 1803 works perfectly. It was a fresh install though. The 960Pro is using the firmware it came with back in October 2017. I am also using BIOS 1301 and latest ME Firmware.
Is your system overclocked?
