Trying a new build and keep getting the same error (cycles through red and yellow LED before settling on the yellow DRAM light). Without the ram in the light still goes yellow so I don’t think it’s a CPU issue but I am stumped.

The build in progress is:

Mobo: MSI MPG Z790I
CPU: i3-1200F
RAM: Crucial RAM 16GB DDR5 4800MHz
Power: Cooler Master V850 SFX Gold
Graphics: Asus ROG Strix RTX 3090

The plan is to switch in an i9-14900K and Corsair Vengeance DDR5 32GB 6000MHz once it’s up and running with the bios updated.

If anyone has any ideas on why this setup isn't even getting to POST I’d greatly appreciate it.

Say what?

Anyway, with a problem like this, on a board where they don't provide a Flash BIOS Button (come on, MSI!), i would first check for bent pins in the CPU socket.

Take out the CPU and take a good look at the socket pins. Check carefully if all the socket pins all look identical in position and in height, from every angle (with a magnifying glass, or take macro photos). Check if some pins look bent in a different way to the others surrounding them (even very slightly), and if they do, make photos of the socket from different angles and upload them/link them here. Accidentally bending some pins happen very quickly on LGA sockets, for example if you're not careful enough during CPU installation or do something the wrong way. That can then cause all kinds of problems, especially RAM-related, a lot of pins towards the right of the socket connect directly to the RAM slots.

Can you provide ram model number. I'm assuming it's CT2K8G48C40U5 and if it is, it is not on the boards compatibility list. Also be aware the compatibility list is different for 13 and 14 gen cpu

Hahaha the i3 is only until we can get the bios updated.

We’ve double-checked it from every angle and can’t find a single pin out of order :(

Took it all apart and put it back together again this morning and still no POST.

No, i didn't mean to make fun of the i3, but you wrote "1200F", what model is that supposed to be? Maybe 12100F?

Also make sure the DDR5 modules are fully in the RAM slots, see here. It seems to require a high amount of force sometimes, more than expected.

You're welcome, glad i could help!

Yes, it really seems to catch some people out how the modules can require quite some force to insert properly. I wonder how many such cases we couldn't solve in the past that were only because of this issue. To think that people probably RMA'd their board over this, it's not a good situation. So i mention this now for every new case that is similar (getting the EZ Debug LED for no apparent reason on a new build).
