This B660 board only has one M2 slot. The manual states: "The Hyper M.2 Socket (M2_1, Key M) supports type 2280 SATA3 6.0 Gb/s & PCIe Gen4x4 (64 Gb/s) modes. * Please be noted that if M2_1 is occupied by a SATA-type M.2 device, SATA3_0 will be disabled."

Is this indication that this M2 slot is actually tied to the chipset vs the CPU? That might explain what I am seeing since I have 4 SSDs installed?]]> Tue, 10 Dec 2024 02:14:52 +0000 https://forum.asrock.com/forum_posts.asp?TID=85182&PID=169043&title=wd-black-sn850x-showing-as-gen2-on-asrock-b660mit#169043 https://forum.asrock.com/forum_posts.asp?TID=85182&PID=169042&title=wd-black-sn850x-showing-as-gen2-on-asrock-b660mit#169042 Author: sspeed

I added a WD Black SN850X Gen4 NVMe to my machine. Motherboard is Asrock B660M-ITX/ac which supports Gen4x4 M2. Western Digital Dashboard is showing it as a "Gen2 (32 lanes). Firmware is up to date.

When doing backups over 10gbit to a Synology 1817+, I noticed that the drive wasn't any faster than the 4 SSDs I had installed. Running HDTune or other disk benchmarks also shows it as just a Gen2 speed.

What am I doing wrong? It is not on the supported storage list. Do I just need to hope for a bios update?]]> Tue, 10 Dec 2024 01:54:53 +0000 https://forum.asrock.com/forum_posts.asp?TID=85182&PID=169042&title=wd-black-sn850x-showing-as-gen2-on-asrock-b660mit#169042
