@canonkong Thanks for your reply, I’m going to buy a Samsung 9100 PRO tomorrow.
I’d also like to ask which MSI motherboard model you would highly recommend? I’m planning to pair it with the 9800X3D and 192GB ram to build the ultimate high-end Windows 7 PC.
You can use 2008r2 instead , 2tb ram. Threadripper 7995wx
I still prefer Windows 7 Ultimate and 192GB of RAM is already enough for me. Plus, the gaming performance of the Threadripper 7995WX isn’t necessarily better than the 9800X3D.
My MSI MAG X670E Tomahawk has been working fine for the past 4 months with a Ryzen 9950X. The only problem was during the initial build where I had to use an older graphics card with a VGA output to see and set the Bios from UEFI to legacy and turn off Secure Boot before the newer graphics card would work.
I only have threadripper 7960x and 64.0 ram 
on Windows 8.
Unfortunately, the MSI MAG X670E Tomahawk is out of stock in my country. I can only choose MSI PRO X670-P WIFI or X670E GAMING PLUS WIFI.
I was considering each of those before I got my current board, so I believe they will work, but I don’t have any direct experience except with the MAG X670E Tomahawk.
I’m curious about why you picked the MAG X670E Tomahawk instead of other options.
The main reasons were the 14+2+1 Duet Rail Power System and the fact that it had the least amount of user reported problems on the MSI forums:

Mr.Kong do you have any confirmation that such chipsets as wrx90 and x870 work with your driver?
Not sure about wrx90, but B850 and X870 can work, but 5G/10G network cards and USB4 can not work.
thanks for reply, please update your starter post with x870 and trx50, just to let people know
