Review: I purchased the B650M-CT-CSM to run Proxmox, with ECC memory, in my home lab. I'm happy to say everything works fine using two Kingston Ksm48e40bd8ki-32ha 32GB UDIMMs w/ ECC. The BIOS isn't graphical but I found it very complete. ECC controls were in the DRAM menu and they include both ECC enable/auto/disable *and* it included an option to enable ECC error *injection*. (I've not tested the latter because I don't have a copy of the 'Pro' version of memtest86+). One of the Asus docs online said the board supports x4/x4/x4/x4 PCIe bifurcation on the x16 slot and I'm happy to report that this option does exist in the BIOS. (Note, I've not tested it). And, to Asus credit, the BIOS *also* has options to enable PCIe x8/x8 bifurcation on the x16 slot with an appropriate riser card. This board doesn't include a BMC (Baseboard Management Controller) with IPMI so some may say it isn't a "real" server motherboard. But, for the price, it's surprisingly good. 5 Stars!
Review: On time shipping and very quick setup for the BIOS and loading drivers. Great for a first time PC build for those looking to get modern computer at a reasonable price. 2 NVME m.2 drive slots and plenty of Sata drive slot for raid array.

### ⭐⭐⭐⭐⭐ Review
*by B***N on 23 January 2025*

Have to say works like a charm. Likes the black on the steel color plates good nice with each other. Got the with a ryzen 5 7600 with 32gb 6000mhz ram paired with my rtx 3060 ti founder and a MSI MAG A750GL PCIE 5 power supply have to say what a computer. Pop on on first boot but give it time for the motherboard to do her thing. The board fits my Corsair Carbide Series SPEC-DELTA RGB is a tempered glass mid-tower ATX case and was easy to install. Lot of people had problems with wifi and Bluetooth but the fix for that is the drivers is in the armory crate program that comes with the board once into windows it would as to install Armory Crate, install it and once it done u can get the drivers right off that but make sure your Internet connection is wired to get the drivers, once that's installed you should have wifi and Bluetooth working. I would recommend this motherboard
