Reply brucedawson says: May 19, 2015 at 11:29 pm Sorry, amd64 usually refers to a processor, not an application, and I have no idea what your problem is. A 32-bit kernel can access more than 4GB of RAM, so having more than 4GB of RAM is not a compelling reason to run a 64-bit kernel. share|improve this answer edited Dec 2 '12 at 17:13 answered Aug 31 '10 at 19:28 Javier Rivera 25.8k66595 add a comment| up vote 13 down vote Intel licensed the AMD64 instruction The processor sets the zero flag and leaves the upper 32bits of the destination undefined.
The BSD family of OSs and several Linux distributions use AMD64, as does Microsoft Windows internally. References ^ "Debian AMD64 FAQ". However, applications that regularly handle integers wider than 32 bits, such as cryptographic algorithms, will need a rewrite of the code handling the huge integers in order to take advantage of Were you reporting a typo?
