Red light CPU help

[Helltech]

8500G is the issue. I have two different configurations I have tried it on. And they are this. 

 

750w evga n1 psu 

AsRock B850m pro-a wifi mobo

Patriot signature ddr5 4800 32gb (2x26)

2080 zotac amp gpu

 

750w (known working) highpower psu 

AsRock b650m-c (known working) mobo

Corsair vengeance 64gb (2x 32) 6400mhz (known working) 

2080 zotac amp gpu 

 

Little backstory. Putting together something very cheap for my friend. The first configuration (giving him the 2080 for free) no post. Cpu red light on the motherboard is on dram light is green post and vga lights are off. I unplug everything plug everything back in reseat the cpu... Same thing. I tried one stick of ram in each slot... Same thing. 

 

So I take apart my own computer and..... Same thing. So I figured the cpu was bad and had him do a return. The return came in today and same problem. Both computer red light on cpu. Reseated everything. Tried without the gpu entirely. Tried with just cpu ram and motherboard. Same thing on both confirguartions. 

 

Could I be missing something?

To understand correctly, you put your own CPU in the system for your friend and it worked or still no post? 
 

my thoughts at the moment are the motherboard needs a firmware update or something might be up with the RAM maybe.. but you did say that you tried just one in different slots and looking at the motherboard Manuel, for 2 sticks it should be in A2 and B2 and just one stick should be in B2.

You waited for memory training, right?

I used a motherboard I had laying around that came from an old build as well as the brand new one. I have not used a different cpu (besides the fact I used a replacement after the first was sent back). Yes I tried the correct ram configurations with both the new and my own ram (known working) ram. As well as a new, and an old known working psu.

I waited about 45 minutes, so I think so.

Did you make sure that both motherboards had their BIOS up to date to support the newer CPU?
