Question New PC not posting, DRAM light on

[Saros777]

Like the title says my newly built computer isn't posting, it starts, but complete blackscreen with the DRAM light on.
Neat thing is that it posts with 1 stick in, in both A1/B1 but not A2/B2 nor dual channel.
I have tried borderline everything.

• Re-Adjusting CPU cooler
• Tried different RAM stick
• Checked RAM compatibilty
• Updated BIOS
• Cleared CMOS
• Checked for bent pins on the CPU
• Disconnected & Reconnected every single cable there inside the PC

Im completely out of ideas, please help.

Specs:
Motherboard - Asus B550-Plus
CPU - Ryzen 5 5600x
RAM - HyperX FURY DDR4 2133MHz 8GB (x2)

What kind of CPU cooler do you have? It could be you tightened it too much. One of the results usually is a non-working second RAM channel. And make sure you press in the RAM all the way. Usually you should hear a click.

AMD Wraith, like I mentioned in the initial post I have tried re-adjusting the cooler, implied I have loosend it, read it could have been the root of the problem, but to no avail. RAM sticks are without a doubt fully pressed in.

You didn't mention Wraith. The reason I mentioned the cooler pressure is because people new to AIOs usually tigten the thumbscrews that should be hand-tightened, people tighten with a screwdriver. Pretty common mistake.
