Is my AMD CPU 64-bit?


I hate to butt in on someone else's thread, but I just want to confirm this myself, because I'm not entirely sure I believe it yet.
Using what's said here in this thread, I thought I'd check my CPU architecture, and if it was really a 64-bit processor in disguise - it's not a recent one, so I wasn't expecting it to.
Anyway, if I interpret the following terminal output correctly... I have a 64-bit capable CPU, right?
Terminal output:
Code:
liam@night-city/~$ cat /proc/cpuinfo
processor	: 0
vendor_id	: AuthenticAMD
cpu family	: 15
model		: 44
model name	: AMD Sempron(tm) Processor 3000+
stepping	: 2
cpu MHz		: 1000.000
cache size	: 128 KB
fdiv_bug	: no
hlt_bug		: no
f00f_bug	: no
coma_bug	: no
fpu		: yes
fpu_exception	: yes
cpuid level	: 1
wp		: yes
flags		: fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt lm 3dnowext 3dnow up pni lahf_lm
bogomips	: 1999.47
clflush size	: 64
power management: ts fid vid ttp tm stc

liam@night-city/~$ dmidecode -t processor | grep version
/dev/mem: Permission denied
liam@night-city/~$ sudo !!
sudo dmidecode -t processor | grep version
[sudo] password for liam: 
liam@night-city/~$ sudo dmidecode -t processor | grep Version
	Version: AMD Sempron(tm) Processor 3000+
I spotted the conspicuous lm flag listed, which as I understand it is a sure way to tell, right?
If this is correct... then I feel kinda stupid for running 32bit systems when I could have been running a 64bit one.

So do we ... which is why I split it out.



Cheers,

Yes, it's 64-bit. Like you said, that lm flag indicates that it is.

Thanks, for that confirmation and the splitting out. I kinda thought it better to use a pre-existing one, rather than start another thread clone, but thanks anyway.

Long mode is the indicator to look for. Easy check is to try a 64-bit liveCD - it'll tell you soon enough if he hardware isn't up to scratch.
