I am very new here and I don't know much, so please excuse any flaws or misunderstandings that I will have.
I just bought a new build with a Ryzen 3900x CPU and suddenly, my MOBO (Gigabyte x570 Aorus Elite), does not recognize the full amount of RAM I have installed (64 in my case), it gives me an error about memory training.
So, what I have found is that BIOS F11 which I am currently on at the moment, sees the only two slots A1 and A2, but when I insert even one or 2 more into B1 B2, the PC won't boot up.
Neither switching them to A1 and B1 or A1 and B2...
How did you get F11 bios? If you updated yourself, did you make sure to clear the cmos? Make sure you drain all power from the cmos look it up, do all methods you find to make sure. I had some issues too but after I pulled the battery and reset the board defaults all was good. Make sure youre in A2 and B2. And remember mem training can take awhile so let it do its thing, but shouldnt take more than a minute or so at most.
I'm not going to do the research but i will tell you.
1. Make sure the RAM is supported by the CPU and motherboard.
2. Make sure the CPU is inserted properly and clamped down correctly, most memory issues stem from a IMC( Internal Memory Controller) Issue.
All the other pins are fine. There is just a broken one. Tried to find it, but no luck. It's location is on the edge of the CPU. I don't have a map of the pins, to view what causes that particular one, but, I assume it's the culprit for the IMC, sockets B1/B2.
In that case, any other solutions or just use A1/A2,
2x32 gb for 64gb?
