I'm having trouble getting a system that I'm working on to boot.
Motherboard: SupermicroH12DSI-NT6: H12DSi-NT6 | Motherboards | Super Micro Computer, Inc.
CPU (qty 2): EPYC Rome 7642 48 core
Memory (qty 16): Micron MTA36ASF8G72PZ-3G2E1 64GB (1X64GB) 2RX4 PC4-3200AA DDR4-25600R RDIMM
CPU and memory were sourced from eBay and motherboard was open box from Newegg. Someone clearly returned the motherboard as there was thermal paste slathered over the cpu cover and latch. There also seemed to be some corrosive material on the outside of one of the occulink connectors. I installed the CPUs and heatsink with a torque screwdriver set to 14 in-lbs.
When I initially apply power, there is a small green led behind the front panel connector that blinks a bit more than 20 times. If I press the power switch it lights up solid green. I have a display hooked up to the VGA port, but it doesn't receive a signal. Similarly, I have a keyboard hooked up to USB (have tried multiple ports) that doesn't light up. I do have the dedicated IPMI LAN port hooked up and the activity LED blinks yellow (right side), but link led doesn't light up (left side). However, I don't see the labeled BMC mac show up in my dhcp reservations and scanning for it fails. I've reset the CMOS and these behaviors haven't changed. I also removed all but a single stick of RAM (also tried powering up with no ram) and behavior is consistent.
I'm using Noctua NH-U9-TR4-SP3 coolers and for some reason, the fans do not spin up when I apply power. They do briefly spin when I power off. If I use 3 pin chassis fans on the same header, they work as expected. This may be something I'm able to rectify if I can get into the bios. I suspect the motherboard is bad, and am debating whether or not to return this and order another H12DSI-NT6 or switch to a different manufacturer. There aren't many reviews for this particular motherboard, but the couple that exist aren't glowing: Supermicro Motherboard MBD-H12DSI-NT6-B SoC Socket SP3 EPYC7003/7002 Bulk item - Newegg.com
