Question Pc not booting after placing second ram stick

[Jehnaa]

Hey I just built new pc and I updated my ram, CPU and Motherboard. Pc booted with 1 stick of ram and worked fine, then i updated bios to the newest version. I placed another ram stick and it wont boot and the dram led is lit. I tried both sticks work on 2nd ramm slot A2. But after placing 1 to A2 and one to B2, it wont boot and the dram led is lit.
I have tried removing cmos battery->cooled it down for 5min

So you performed a partial PC upgrade after building your PC?

What BIOS version are you on for your motherboard?

ram: corsair vengeance 6400mhz 2x16gb ddr5 CL36
Got a link to the ram kit you're working with?

How are you cooling the processor? Might want to inspect the CPU's socket for any bent or broken pins. Since you'll be inspecting the socket, when you place the cooler for your processor, merely rest the cooler on the CPU's IHS. You'll need to have the PC on it's side if it's built into a case in order to do so.

Im using bios version: F4i

Cooling the processor with: https://noctua.at/en/nh-u12s this one.

Ive checked that cpu pins are fine as the pins are on the cpu socket not on the actual cpu.

Thanks for starting to help me.

Any ideas what could be wrong?
