Windows 7 BSOD - AMD 1950x Threadripper - Win7

[Jollyriffic]

I'm stuck and need help.
Hardware:
asrock pro gaming x399 (latest bios)
1950x (custom liquid cooler with phantom block + 420gtx nemesis rad)
msi gtx 970 gaming 4g (latest firmware, stock dual fan cooler)
crucial ballistic elite 2x 8gb sticks at 3466mhz
corsair commander pro for the fans (updated/latest firmware) running 6x fans
Seasonic 850w Focus plus gold
Acer xz350cu monitor 2560x1080 144hz on display port
240gb Silicon power SSD (operating system)
960gb silicon power SSD (games drive)

Operating system is win7 64 ultimate.
Updated till w/e is out right now.

The problems seem a tad random, i'm currently overclocked, only because being at stock values gave no better result.
I was using win10 without much issue other than win10 being a big box of bugs.
I prefer win7, so that's what i want to get working.

This is a fresh install as of this morning
These issues have been present since the first boot of windows 7.
It's also not new, i've tried win7 before and had bsod issues that forced me to go to win10

Probably caused by : pci.sys ( pci!memset+2b )

Hi,
this is probably down to a driver but trouble is which one? I have a suspicion that your chipset driver could be to blame:

Chipset

When you updated your drivers did you use the drivers available from your motherboard support page? If not, try uninstalling your current drivers and install the set from the page shown below (the latest chipset drivers from AMD have a new pci driver which might not be compatible with win 7):

Also notice the beta support patch at the bottom:

Reference:
ASRock Fatal1ty X399 Professional Gaming

i used the ones directly from the asrock page for 7, but i think it's the same as win10.
also tried amd's page download
last ditch effort i used sdi-tool.org to try and resolve it.
any chance you could zip up exactly what i should use or give direct links to what you think would work?
10 works ok, but i'm trying to do direct benches with streaming + gaming between the two. I've noticed a lot of poor performance with streaming under windows 10 vs win7 (i fix about 7 streams a day for users and many people i've helped swap from 10 to 7 in order to get far better cpu encoding presets).
the difference is huge, like medium preset on 7 vs 10 only being able to do about veryfast or super fast.
sorry for the dealy on my reply i lost the forum url after having to put win 10 back on again.

If the x399 is anything like the x370 with the latest firmwares, Windows 7 isn't supported.
