Thanks for your posting about the TXB122 PCIe 3.1 x8 ASM2812 . I followed your photos and got the taping right on the first try. It was a struggle to get the card into the MS-01. The fact that I could see that you achieved getting it in kept me going. The card with two 4Tb Nvme drives works fine, if not hot. I now have 20Tb working on the Ms-01.
