I'm curious if it's technically feasible to load TinyCore Linux directly into L3 cache instead of RAM to maximize loading speeds. I know it's possible to load entire distros into RAM using the 'toram' option. Since my Ryzen 5 5600 has 32MB of L3 cache and TinyCore Linux is around 20MB, in theory, this could work. Has anyone tried this or can someone shed light on whether this is actually possible?

I haven't seen anyone actually pull this off. The idea of using L3 cache like that is cool, but it's not how computers are designed to work. Cache isn't replaceable storage!
With the wild fluctuations in RAM prices these days, I can see why people might think outside the box! But remember, cache is a vital resource needed to feed the CPU cores, so using it for something like this might not be practical.
Max speed of what exactly? Just to clarify, are you asking about the loading speed of the operating system?
That's a really interesting idea! However, the L3 cache isn't meant to be accessed directly. It's utilized by the CPU to store frequently used data automatically, so you wouldn't be able to load an OS directly into it. It’s designed to optimize performance, not serve as a storage space.
