This is a new build, AMD 3700x, Gigabyte Aorus Elite X570 mobo, Gskill Ripjaws V 8gb 3200 ram x2.
When I first built this PC I could not get it to post at all. No beep from my mobo speaker, all the lights would go on besides the orange one on the mobo, and no post screen. So I RMA'd the mobo.
Got it back, and it posts. However BIOS does not see my ram in slots B_1 or B_2, and I get a Memory Training Error. Windows only sees 8gb of ram too.
As long as I have ram in slots A_1 and/or A_2 I get a post screen. (so I can run them both in single channel) If I just have sticks in B_1 and/or B_2, it doesnt post. This leads me to believe that it is not a ram problem, but a mobo/cpu problem.
Ram only runs at 2133. If I try to run XMP profile 1 it fails to post (bios resets).
Another thing that is weird is that CPU-Z sees the memory in slots B_1 and B_2 if it is in there. Something is still messing up in the memory tab, as the Channel # is not filled out and DC mode is completely greyed out when running in A_2 and B_2. (although for size it shows 16gb)
This would make me think that it might be some CPU error, but all the pins are straight and clean, and it sits well in the socket.
I've flashed to the latest bios version (F11), reset cmos, reseated the CPU multiple times, to no avail.
Obviously something is still wrong with the motherboard, or wrong with the memory controller on the CPU. Is there any way to tell which one is the problem? Is there any other troubleshooting I should do?
I appreciate the help, this build has been a nightmare so far.
