Hi There, I have bought a new B650i Lightning WiFi board for my desktop and my X570 Taichi board moved to my "server". It has 128GB RAM and I was using 3x5090s (Pcie 2x PCIE4x8 1x PCIE4x4) and it was working perfectly fine. I've bought a RTX6000 and replaced one 5090 with it but motherboard wont boot afterwards. (it will boot with 1x 5090 and 1x RTX6000). I'm on newest bios from a few weeks ago. I think there is an issue assigning ~160GB VRAM which leads to D7 (or 07) code on DrDebug display. I have waited for hours but its just stuck there. (also I've tried a lot different PCIE Bios settings but nothing worked... Any chance you can help me£ Thank you very much |

Hi Goetterfunke, you will likely need help for ASRock's Tech Support staff with this, more specifically, their BIOS department. I would open a ticket with them and outline your issue: https://tw.asrock.com/events/tsd.asp" rel="nofollow - https://tw.asrock.com/events/tsd.asp This kind of issue often requires a BIOS level tweak or fix. It seems you have already done what I would have suggested as troubleshooting. Good luck and let me know how it goes  -------------
