Dual Channel Memory not functioning?

[Ankelbiter12]

   Hey Guys, so life’s been chaotic, I’m moving a few miles away and for reasons it’s a lot of preparation and planning and with work, I haven’t had a lot of time to work on this pic build I just did and I just want it over with. 
I got the following hardware 

EVGA B5 650W power supply

orginally GIGABYE AEROUD H470

now ASUS ROG Z490E

i3-10100

MSI GEFORCE GTX 1050Ti 4GB

Some basic $45 cooler master cooler

16GB(2X8) of Trident Z RGB DDR4 3600mhz ram

basic Storage

 

    So initially I went to build it and I got a cpu error on the leds so I went to Best Buy and temporarily bought and eventually returned a different 10th gen processor, i noticed the board had bent pins. So I go back to Best Buy, return the processor, get a different board, unplug all the cables and get everything set back up, then I’m getting code 55 with the dram led lighting up.

    So I troubleshoot and here’s what I’ve found 

1. both sticks function on their own in slot A2

2. without functioning ram(no led) I can’t get to bios

3. neither stick of ram functions by itself in slot B2

    i have made sure I’m following the manual for ram and it does want me to use these slots, basically numbered left to right, slots 2&4

Did I get a faulty board again?

That's what it looks like. If both sticks of ram function in one slot but neither stick functions in a different one, that looks like a motherboard defect. If you still can, try to return the motherboard and get a new one.

clear the cmos.

and am i getting this correctly? b2 does not postr but a2 does.

try slot 1 and and 3 and check as well. re seat the cpu and check. check for any broken memory channels on the cpu.

You’re killing me even though you’re just the messenger, ugh!

Will try both tips when I’m done unpacking today, I’ve already reseated cpu, and you are correct, but the manual states that if I had one stick of ram, to use A2, so I’m not sure if B2 would post by itself. How would I check for broken memory channels on the cpu? Did you mean motherboard, again, if so, how would I? They visually all look identical and normal

Look at the side of the cpu. And check for anything that looks damaged.

Clear the cmos and try that.

No doesn't really matter. It's just a troubleshooting steps for now. 

Just try every dimm on the board and check if it posts. 

Try slot 1 and 3 and check.
