Recently, I wiped Windows 10 completely and installed Ubuntu 20.04. What should I do? Was my RAM ever bad? Or, was it somehow just a mechanical pin alignment or debris issue that somehow got resolved simply by me unplugging and plugging back in the RAM? Now that no errors are coming up I wonder if that is just more risk than I need right now to let them swap the entire motherboard, especially since they will be using refurbished parts, and my experience with refurbished hardware parts in general (not with Dell at all-but just in general) tells me to stay away unless I really have no choice. It's under warranty, so Dell is willing to swap the entire motherboard and both RAM sticks (8 GB each), for free, this coming week, but I'm thinking I should reject the offer but I am worried my hardware may still be bad. It seems my RAM was bad, since I found about ~6000 errors in Memtest86+, and I had 10+ freezes and hard reboots in 1 hour, but now that I've simply unplugged both RAM modules and plugged them back in, I can't get a single new error.

Select Memory and continue to purchase the memory.I asked this question on AskUbuntu, but have more specific hardware questions I'm asking here now.

Identify your Dell computer using the Service Tag or Express Service Code.

A 64-bit version of operating system can support system memory that is greater than 4 GB. Adding a higher capacity memory in such cases does not improve the performance as the operating system cannot take advantage of the available memory.

If the computer is installed with a 32-bit version of Windows or other operating systems, the operating system can only recognize 4 GB of memory.

See the documentation of your Dell computer for model-specific information. For example, if your laptop with 2 memory slots supports a maximum of 16 GB of memory, you can install 2 x 8 GB memory modules. Often laptops have 2 memory slots, and desktops may have more than 2.

Every computer has a specific number of memory slots on the system board.

For example, a particular Dell desktop or laptop may support a minimum of 2 GB and maximum 16 GB of memory.

Every computer is designed to work with a minimum and maximum capacity of memory.

What is the maximum capacity that is supported by the computer?.

WARNING: Installing an incorrect or unsupported type of system memory (RAM) on the computer may cause physical damage to either the module or the slot on the system board.
