https://community.intel.com/t5/Mobile-and-Desktop-Processors/Intel-Core-2-Solo-SU3500/m-p/313606#M8095 <P>I found a small notebook I want that comes with the SU3500 processor. My confusion is whether it is a 32Bit or 64Bit processor. The OS that comes with it is XP Pro- Not the 64Bit edition. Several sites I have visited says this processor <B>"supports" </B>64Bit processing. The specification page for this processor states <B>"Intruction Set-64 Bit". </B> Does that mean it normally runs in 32Bit mode? I would prefer a 32Bit procesor due to having quite a few older XP programs. Any help would be greatly appreciated. Thank-You</P> Tue, 20 Oct 2009 02:13:02 GMT idata 2009-10-20T02:13:02Z https://community.intel.com/t5/Mobile-and-Desktop-Processors/Intel-Core-2-Solo-SU3500/m-p/313606#M8095 <P>I found a small notebook I want that comes with the SU3500 processor.
