I am so confused at the point of this thread... I'll do my best to piece it together.
1. No, it's not possible to add RAM to the D3.
2. The D3 uses NVRAM (Non-Volatile Random Access Memory) This means that your data is kept even without power. This is very different from your standard off the shelf (volatile) RAM.
3. Even if you were to desolider the NVRAM and replace it with bigger NVRAM, I doubt the unit would behave any differently.
4. I don't know what this has to do with anything, but....I don't own the PHYSICAL server hardware (GoDaddy owns that), but I do in effect still own the server since it is provided to me on a lease, just as you would own a leased car.
I think that pretty much covers everything that was questionable.
