Smile 64 Bit Slackware

I need to install a software which requires 64 bit OS. My current Slackware box is 32 bit.
These are results when I typed in lscpu:
Architecture: i686
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 1
On-line CPU(s) list: 0
Thread(s) per core: 1
Core(s) per socket: 1
Socket(s): 1
NUMA node(s): 1
Vendor ID: AuthenticAMD
CPU family: 15
Model: 44
Stepping: 2
CPU MHz: 1608.086
BogoMIPS: 3216.17
L1d cache: 64K
L1i cache: 64K
L2 cache: 256K
NUMA node0 CPU(s): 0

Can someone tell me whether I can install the 64 bit slackware on this machine?

Thanks for your help in advance.

Well these are my specs (it's a Sempron 140) and Slackware 64-14 runs fantastic on it:

This should be an indication that a 64-bit OS can run on your CPU.

I have an Intel Atom 1.6Mhz n330 running Slackware 14.0 64 bit. Runs a little slow with the full KDE WM, but still very useable (my daughter hasn't complained). Would be fine with Fluxbox or XFCE.

AMD Sempron(tm) Processor 2600+ Family 15 Model 44 Stepping 2

Not all Semprons based on Athlon64 core are x86_64. Check
$ cat /proc/cpuinfo
and look in the flag line for 'lm' (long mode) for 64-bit support. The fact that lscpu labels Architecture as x686 is a hint. See here for Sempron stats and history: AMD64/x86_64 Semprons didn't pop up until 2005 and then only for Socket AM2 or newer (some socket 754, 939 stepping only). From the available information, I'd say you CPU is 32-bit only.

You can also use this: to get more info than you ever wanted from the CPU.
