I purchased 19 GPUs from LUCBIT in December 2023, and unfortunately, all of them are faulty. When booting, they display strange, funky colors, and various issues have emerged. Some fans are noisy, some GPUs randomly restart my PC, some fail to start or complete stress tests, and a few do not power on at all. In response to my concerns, LUCBIT provided videos showcasing graphics cards undergoing benchmarks, but the GPUs I received do not function as they claimed. Their proposed solution is to send me replacement fans, and they expect me to send the graphics cards to experts capable of performing board-level repairs. LUCBIT will supply the necessary parts. This is not feasible as we dont know if its repairable at all. I expect a full refund. It's worth noting that they do not offer any form of warranty for their products. I have 19 graphics card that I can not resell.
