ask lang po sa mga naka AMD processor . . nakaset po ba sa processor kung x64 or x86 yung system? kumbaga di na yun mababago?
x86 instruction set... 8bit and 16bit instructions set - https://en.wikipedia.org/wiki/X86
x86-64bit instruction set... https://en.wikipedia.org/wiki/X86-64
google mo na lang at mahabang paliwanag kung di sapat yung link sa wikipedia
kung Operating System ang tinatanong mo, pwede ka mag-install ng kahit ano sa 2. pero syempre, mas marami advantage ng 64bit na OS like higher RAM capacity ang a slightly more efficient instruction set. you can install/run 32bit programs on a 64bit OS pero not the other way around.
