Any Core 2 Duo processor is capable of 64bit handling, this includes Merom CPUs (T7xxx) and the newer Penryn CPUs (T8xxx & T9xxx ).

 

The platform you speak of is the motherboard chipset version (or cycle in manufacturing terms). ]]> Tue, 08 Jul 2008 22:07:27 +0000 https://forums.lenovo.com/topic/findpost/1307/32121/32139 icantux
