Hello, first of all, congratulations for the successful build. I have a system based on this guide: Gigabyte Z690 Gaming X DDR4 board with 12900K. At the moment, I stick to BIOS F8. Any higher BIOS does not recognize my Thunderbolt Titan card.
I have verified that the DDR5 memory does its job, and I am going to upgrade the motherboard and the processor to a 13900K. But I have doubts as I want the Aero G DDR5 model. However, I don't know whether to buy the Z690 or the Z790. To maintain compatibility with the guide the Z690 would be better, but I'm afraid that it won't recognize the Thunderbolt card. I don't know if the Z790 would keep the Thunderbolt, either. The problem is that, if I keep on an older BIOS, there is no problem with Thunderbolt. But the old BIOS doesn't work with 13900K, and the new BIOS...I don't know if they will work with Thunderbolt.
I'm in a mess. Can someone shed some light on this? Thank you and congratulations for the work done. Regards.
