64bit running on an old Celeron D, I don't even know?
This processor never ceases to amaze me, people have told me it is utter trash, it looks like utter trash, and then I overclock it to 4.5ghz without any issues. Now, I have come across something new, and even more astonishing. Despite the fact it's architecture is supposedly 32bit, I installed(accidentally) a 64bit distro of Ubuntu to it's new drive, and it has run without any issues. I'm even using it to post this. So my question is this; what exactly is going on here that I am missing? How did this even work? Isn't this mathematically impossible? ( Yes, multiple questions, I'm aware. )

Several models of the Celeron D were 64-bit architectures. From the link below, posted in 2005:
The first Celeron to support EM64T, Intel's 64-bit extension set, is the Celeron D 351. The chip is clocked at 3.2 GHz, carries 256 kByte L2 cache, works with a 533 MHZ FSB, comes in a LGA775 package and can be combined with Intel's 915 or 910 PCI Express chipsets. Also shipping with EM64T are the versions 346 (3.06 GHz), 341 (2.93 GHz), 336 (2.8 GHz) and 331 (2.66 GHz). Consumers can recognize the 64-bit processor by their specific model numbers - the numbering system 3x1 and 3x6 is reserved for Celeron Ds with EM64T support.
