I had a replacement shipped by Amazon but it has the exact same problem. I'm at a loss for what to do. I can try calling MSI tomorrow morning but I don't have high hopes. If I start returning the RAM and the CPU Amazon will likely be pretty unhappy with me.

I had a friend come over and help me clean off cpu/heatsink and reseated it. I've also tried using just a single stick (tried every one of my four by themselves). Still stuck with EZDebug on DRAM and hex display C0

Hi, trying to setup a new AMD TR2 2990wx build. I have never gotten it to POST. I've never been in the BIOS or installed an OS. I have double checked all power cables, flashed the newest bios, reset CMOS, tried reseating ram in dozens of configurations, but still can't POST. There's a hex display that gets stuck on C0 which is undocumented in the manual. The EZDebug LEDs show CPU for maybe 5 seconds then get stuck on DRAM. Is there anything left to try besides ripping everything apart to reseat CPU or RMA it? I spent several hours carefully building so I really don't want to do those Motherboard: MSI X399 GAMING PRO CARBON AC CPU: AMD TR2 2990wx Memory: 4x8GB 3200 G.Skill F4-3200C14D-16GTZSK GPU: Nvidia GTX 770 PSU: EVGA 1000w Other: An M.2 drive and 5 SATA drives.
