Review on LINKUP - Extreme4+ PCIe 4 by James Cash

TL/DR. Works for me at Gen 4 speed without freezing. Full Story. Asus Strix X570-F with BIOS version 3001 (latest version 12/8), CPU 5800X, 3600 CL16 Ram, Zotac 3090, Sabrent Rocket Gen 4 M.2. All Gen3/Gen4 related settings are set to automatic in the BIOS and always have been. I set up my GPU for vertical mounting with this cable without any further modifications and voila. Booted directly into Windows. The games run perfectly. No stuttering, weird noises or anything else I've read about in reviews. No problem changing the BIOS from automatic to Gen 4. Reviews are the reason I am writing this. I myself was nervous spending so much money on a part I wasn't sure about. Your mileage may vary, but I've had absolutely no issues with the gear listed above. I hope that was helpful.
