Hi.
I have an issue with my livemixer z890 motherboard. I've installed 3 nvme ssds. All of them are gen4 drives- lexar nm790, samsung 980pro and crucial t500. Lexar is conected to the gen5 slot, samsung is conected to the slot whitout heatsink and those drives runs with gen4 speeds. My crucial drive is connected to the one of slots that are covered with heatsink. CrystalDisk Info shows that crucial is gen4 disk but when i run any disk benckmark my speeds are very low. write speed is barely above 3500mb/s. i'm on 3.08 bios with ultra core 7 265kf. I've disabled sata ports in the bios, and manually changed all nmve slots from auto to gen 4 in bios. It didn't help at all. Do i need to change something else in bios?
