Look at this.

I put a 8 GB stick in, and have 5.7Gi available, in Linux. If you add two, that’s 7.7Gi, whatever Gi stands for. Is it GB?

Might be the type of RAM, in their case.

Good idea, buy a 16 GB stick, and see if I get more then 8 GB. I have the latest BIOS. This RAM apparently works in the 2018 Mac mini. I might be to anxious to upgrade it. Can my grandpa see well enough to help me? I just need him to make sure I don’t break it, and possibly help plug small wires in.

The dual rank might be the problem. Except, I think it works on the M142. So, they might of crippled it in the BIOS. Whatever dual rank means, don’t think there’s a 16 GB stick that is single rank.

I’d rather upgrade the mini to 32 GB of RAM, I think the max is 64 GB, but I might be to cheap to get that much. That way, I never have to open it again.

So where is that second slot? On the other side? I’ll never know. Shouldn’t the locator be different if there’s two slots?

Might be under the stock SSD. I’d need to clone it to the other SSD if that’s true. But I don’t want to leave the other M.2 slot empty. Nope, false info, another video looked for it, and it wasn’t there.

Got to love YouPoop.

Only one slot, don’t believe YouPoop.
