Intel Pentium 4 SL7D8

This link says it's a 64-bit CPU, is that correct?

I've always thought all socket 478 CPUs are 32-bit.

Oops, never mind. That link actually gives info about the S775 CPU with the same speed.

P4 s478 line was 32-bit. I think only some of the Xeon Itanium or whatever had some EMT64 code.

There were p4 775 CPUs that are 64-bit, the one I remember was the 631, which was a 65nm beast

edit. I think the p4 775 CPUs that ended with 1 were 64-bit, but that's just from memory. Also, I bet no 478 CPU ever was 64bit capable.

Maybe that one?

Lots of P4s supported "Intel 64" http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors... too many I care to list. However none of them are Socket 478.

Hagrid, you linked the same one the OP did.

This thread is like a blast from the past.

None of the released Pentium 4 or Pentium 4 EE S478 processors supported EM64T. I'm sure someone somewhere may have an ES with EM64T enabled, but none were ever released a consumer products. Even if you had one, good luck getting a motherboard which would support it (because often you'll just get a blank screen at POST or the processor locked into a low speed mode due to not being recognized).
