[Solved] - DIY AI 340 black screen and flashing LED 0xC5 code - RAM issue?

Today I tried assembling my AMD AI300 framework, and put in 2x Fury 16GB sticks ( KF556S40IB-16)… power button lights up but the screen is black. In my case the code is BGBGGGBB. Not sure if I should try to return this RAM and get a different pair.

Also, there is another customer with the same error code with Kingston Fury KF556S40IBK2-32
