Threadripper 1950x low benchmark score

Conclusion on the Windows drive: Q32T1 Read results appear to have tanked by 450 MB/s with Windows installed on the same drive after the Spectre / Meltdown patch, although results always seem to be inconsistent when Windows is installed on the drive to be benchmarked. 4 KiB Q8T8 Write INCREASED by 250MB/s after after the Spectre / Meltdown patch on the Windows drive. Margin of error on an inconsistent benchmark? I dunno.

Conclusion on the non-Windows drive: Within margin of error on all tests. The Spectre / Meltdown patch does not appear to have affected drives that do not have Windows installed, at least with ASRock X399 & MS Drivers.

It seems I have lost about 2%-5% of my CDM scores. This is with an SATA 1TB drive. I had heard that M.2 drives are more affected though. Since AMD supposedly is only in jeopardy if the current user is there to place it in troubles way we should be given the opportunity not to use the patch, at least that is my opinion. 

I only have Passmark and CB R15 and neither went down.

Personally I have no idea what had caused the issue. I am now monitoring performance after every action i take just to be sure.

Me, no. I have installed mostly everything with Macrium run at each step to create images, of course I tested them first. I also just went to the 1709 Accumulative Update as well. Still have a few things to install, like a PDF reader etc..
