Question ryzen 5800x on msi mpg b550 gaming plus mobo - not booting

[murfilein]

currently i have a alienware aurora r10.

ryzen 5800x, 2x16gb hyperx fury ram, 3060ti

since this system is loud and hot, i want to put these components onto a new motherboard and case

bought the msi mpg b550 gaming plus motherboard. corsair rm750e psu, arctic liquid freezer 3 aio

i built the system on my table before putting it in the case. after issues i installed the latest bios via the flashback feature.

now when only the cpu is on the board, the debug led jumps from cpu to dram. so far so good. but when any ram is installed, 1 or 2 sticks, the cpu led comes on, quickly jumps to dram, then back to cpu and stays there.

What's going on? is that a ram issue? for now i put the hardware back into the alienware - working perfectly fine.

i believe i read that they hyperx dell uses differs from the regular hyperx... could this be the problem? i have no access to any other ram.

first boot can take few minutes, so it can train your memories
you could try with single stick in A2 slot if it lets you POST

i did, for around 10 minutes.

would the debug leds just stay at cpu, or would they jump around while it's being trained?

it would shuffle and reboot few times during training

that did not happen during the 10 odd minutes i waited... i requested a new motherboard from Amazon. hope this will sort it, otherwise i will have to try to get my hand on a different set of ram i guess.
