Hello,

I got a Dell Precision T3500 for free and I want to use it as a cloud server but it came with 6GB of RAM only so I bought 6x4GB DDR3 RAM non-ECC unbuffered and then installed Ubuntu Server 24.04 LTS.

The mobo has a W3520 installed.

The problem is when I boot up the system kernel is only detecting 16GB of RAM usable but when I check the hardware installed it shows up that there's 6 modules of 4GB having a total of 24GB.

My questions are:

- the Dell Precision T3500 has any limit? I read that the limit of the mobo is 24GB but that's because of only allowing 4GB modules.

- the CPU itself has any limit? Searching about it looks like it doesn't have any limitation like this.

- how do I fix this?

Thanks in advance.
