I have got this AMD AM2 64bit computer for three weeks. But Currently have no Windows XP that support 64 bit computer. For useing full power of this computer, I use Ubuntu 7.04 for 64bit, That works well. only got some trouble for install skype, skype have no version supporting 64bit computer.
To make sure I'm in 64bit support, I write a C code and run on this computer with only one line in the main function: printf("Size of long%d\n", sizeof(long)), the result is 8, that means I'm useing 64bit OS now.
