[SOLVED] RAM channel B is not working?

[fantomsloth]

Hi all!

I recently had to get a new motherboard and reused my previous parts. I noticed that the PC will only POST (might use this term wrongly, what I mean that everything lights up, fans are spinning, but I don't even get to the BIOS screen) if I have memories in channel A. I originally have 2 memory sticks and it worked in my previous build. I also tested only using one of them and swapping them out to make sure it's not the RAM's fault. But as soon as I put it (even if only 1 stick) to either channel B I get the same problem.

I did some searching found out not long ago that the RAM that I own is not on the compatible list for my motherboard, but I feel like it shouldn't cause these problems.
The BIOS is updated.
If I take out the CPU is there a way to check if something is wrong with it, or its a faulty motherboard?
I just hope it's not my CPU because I can't replace it...

Also would it cause any 'trouble' to use my PC as is and put both memory sticks in to channel A1 and A2?

You would check for bent cpu pins. A2/B2 are the primaries and need these slots operational for dual channel and also less complications getting xmp to run so wouldn't settle for A1 A2.

Check cpu pins and don't have cooler on super tight, this can also affect cpu. Just like finger strength until screw stops then half turn more screw driver strength.
