Another slight update... managed to sysprep my current installation of Windows 8.1 x64 (BIOS mode) on an X79 system to ASRock's X99 WS-E after doing the following in Powershell:
Get-AppxPackage | Remove-AppxPackage
Get-AppXProvisionedPackage -online | Remove-AppxProvisionedPackage -online
Also, delete HKLM\System\Setup\Upgrade key, as well as HKLM\System\Setup\Upgrade DWORD in registry editor.
Finally, point it to an Unattend.xml with this text:
|
and run sysprep with:
sysprep /oobe /generalize /shutdown /unattend:Unattend.xml
The first step to get sysprep running was to get rid of any system upgrade regkeys and indications. Next, had to keep drivers because NVIDIA drivers were not playing nice and sysprep was failing. Finally, the powershell commands remove all Windows 8.1 apps and de-provisions them, because otherwise sysprep will also fail.
One last thing that took a while to debug was that DPC latency was pretty horrid when I tried to play a Youtube video @ 1080p in Chrome. System process was shooting up to 20 or 30% causing slowdowns and 100% CPU usage and Chrome was using 20-30% CPU to play the video... almost as if hardware acceleration was broken, yet chrome://gpu showed it was enabled.
I ended up using a spare drive to install a clean copy of Win 8.1 x64 and Win 10 x64 (both in BIOS mode) and the same problem persisted. I removed the 32GB ECC DIMMs and inserted a single 16GB UDIMM and the problem immediately went away... Chrome went back to using 2-6% CPU usage to play video and System process never went past 0-2% CPU usage. I replaced the ECC DIMMs 1 by 1 back until I had 5x32GB (the amount I'm intending to keep) and the problem was still gone both in the new clean install and my transplanted sysprepped image.
So needless to say it's possible that either there was some weird BIOS corruption or that the DIMMs were not seated correctly to begin with. Figured I'd add all this info in case anyone else (or myself again, ha!) ever needs it.
System now has 1x GTX Titan X and 1x Quadro K6000 functioning well... will add the remaining GTX Titan Black once I clean up the cabling and add a few other components here and there (Blu-ray drive, hotswap SSD caddy, etc)
RAM was tested up to 140 GB processing some huge electromagnetic data sets, very happy with this new setup after all the platform tweaking to figure out its quirks.
