I've got an extra 4-pin connector, but it is supposed to be for extra power. I've connected both the MB 24-pin connector and the CPU 8-pin. It does boot fine, and no RAM related error codes are shown in the debug display.įirst thing it came to mind, was power issues. For instance, it says I'm using Dual-Channel RAM, not quad. The UEFI bios says only 16GB are detected and on slots B1 and D1 (the innermost slots, next to the CPU). I'm using a Xeon 2620 v4, RAM is plugged on slots A1, B1, C1 and D1, as per documentation, but it fails to detect all 4 modules.

Any settings I need to adjust? If I interchange the ram in other slots, the Nuc won't boot. Both Bios (UEFI) and Win 10 detect the two 4gb modules, but Ubuntu 22.04 doesn't. I suspect it's only detecting the Kingston one. I have a 4gb Kingston ram module and a 4gb Crucial ram module. I think this is the relevant part of the output:ĭescripción: SODIMM DDR4 Síncrono 2400 MHz (0,4 ns) So, any ideas which of the two ram readins could be the right one and I should trust? I guess that the first ram slot may take the lead when determining the frequency for the second module. I tried swapping the modules position in the slots, but the Nuc wouldn't boot. I can't tell if the frequencies are the same because on the Kingston it's not indicated. One is a Crucial module and the other one is Kingston. Only issue I see is that they are not the same.

Those two 4gb module were installed in my previous intel nuc and they were working fine. What information is wrong? What information should I trust? Ubuntu is running quite smoothly, so I suspect it's an error (possible bug) in the settings>about info.

However, if I run free -h in the terminal I get 7,4Gb. If I go to settings>about it shows 4gb memory. Win 10 also detects 8gb, but my problem is with Ubuntu. I'm running dual boot win10 and ubuntu 22.04.1 lts. I've just bought a new intel nuc with 11th generation chipset.
