Whenever I try to install more than 1 stick of RAM in the motherboard, I get a long white RAM EZ-Debug LED with a quick blip of the CPU LED before going back to the RAM LED.
Specs:
MZI Z390 Gaming Pro Carbon motherboard (with latest beta BIOS from 11/2019)
Intel i7-9700K
4 x 8 GB G.Skill TridentZ RGB DDR4-3000 (F4-3000C16Q-32GTZR - on the MSI compatibility list for this board for 1, 2, and 4 sticks)
1 TB Samsung 970 EVO Plus NVMe installed in slot #1 (between the top PCIe slot and the CPU)
Using the onboard video or an old Radeon HD card (I'll install my existing 1080 GTX once I get the system up and running I can migrate off my older desktop).
If I install 1 stick of RAM in the first slot, it comes up and tells me to install the RAM in the 2nd or 4th slot.
If I install 1 stick of RAM in the second slot, it comes right up and boots (I tried all 4 sticks, individually in this slot without issue)
If I install a 2nd stick of RAM anywhere (preferred/optimal slot is #4, but it doesn't matter where I put the 2nd stick as the behavior is always the same), I get a long white RAM EZ Diag LED, with a quick blip of a white CPU EZ Diag LED.
I really want to be able to install all 4 x 8 GB DIMMs for 32 GB RAM.
At first I thought it was a BIOS issue, so I went to update it. The board had the latest GA BIOS, but the beta BIOS from November showed updates for memory compatibility so I installed that.
I did verify that the BIOS is detecting the one stick properly (CL16-18-18-38 and 1.35V)
I was able to install and update an OS on the 1 TB drive with only 1 stick installed, so it sounds like most everything is working properly, except the motherboard.
I originally thought I had a power supply issue as my new 650W power supply did not have 2 x 4+4 connectors, so I ordered another brand new power supply (this time 850W) so I could have a model with 2 x 4+4 connectors to ensure that the CPU was getting the power it needed.
I have reset the BIOS multiple times throughout this process.
Do I need to RMA this board?
