This is fabricated on 90nm process technology, uses FC-LGA775 package, and operates with 3.20F/3.40F/3.60F GHz and Intel 925X Express chipsets. The corresponding S-Spec numbers are SL7L9, SL7L8, SL7LA, SL7NZ, SL7PZ, and SL7PX. Note that processors marked as 5xx numbers do not support EM64T. " Yes, there are only two x's in the last sentence. Does that refer to another processor type? Regards, Rene -- http://www.rene-ladan.nl/ GPG fingerprint = E738 5471 D185 7013 0EE0 4FC8 3C1D 6F83 12E1 84F6 (subkeys.pgp.net)
