[SOLVED] Framework 13 AMD Ryzen 7840U w/ 96GB of RAM (Troubleshooting)

Hi there,

I’ve just received my AMD Ryzen 7840U mainboard; I’m updating from an Intel 12th gen. The upgrade went smoothly, but I chose to try sticking 96GB of RAM in the machine to see if I could make it work. I’ve read many posts in this forum from people who have been successful in doing the same, so I decided to give it a try.

I went with Crucial CT2K48G56C46S5, and after installing it and booting the machine I see only 16GB being recognized. The initial memory training, which was supposed to last for at least a couple of minutes (from what I gathered), finished in just a few seconds.

I checked and I have the latest BIOS installed (3.05). Aside from this problem, everything else seems to be working fine.

Now, I understand that this scenario is not officially supported by Framework, and that’s OK. As I said, I know that at least a few people here managed to make this work, so I’m wondering if we could exchange some ideas on how to troubleshoot this problem. Worst case scenario, I can return the RAM I bought and get 64GB instead.

Thanks in advance!

Huh, dmidecode reports the memory model as being CT8G56C46S5, which is really strange.

I think you need to return the ram. Sounds like they sent the wrong ones.

What do the labels on the sticks actually say?

5

The labels are correct, they contain the expected size (48GB) and model number on both sticks.

Interesting, do they have 8 modules soldered on to each side? Looking at pictures of the 8GB modules they only have 4 on each side.

This is what my own 48GB modules look like.

Nope, mine only has 4 modules on each side!

I think I’ve been bamboozled by Amazon. I’ll initiate the replacement process right away. Thanks a lot, this picture really solved the mistery.

Glad we could get it sorted out! I picked mine up from a place I trust locally. Hopefully, the refund process isn’t too painful with Amazon.
