Review: quality - very good old bios design.
Review: Surprisingly capable Proxmox server motherboard - 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!
