I sold my Intel E6600 for a Pentium 4 it has 4 cpu's on one chip so I install it now my pc just beeps.

You mean you sold it for a quad, prolly a q6600 right?

No a Pentium 4

there are no pentium 4's with 4 cpu's so you would be mistaken, also if it is a p4, your talking about 2 diffrent socket types, socket 478 is p4, and is a downgrade to your e6600 whick is sockedt 775, and faster then any p4 that was made.

^There are P4s on LGA 775, like the P4 540:

Yes, and you are correct about the P4s NEVER being Quad cores. Intel never released P4 Quads.

OMG what are you doing OP?

I know, but there are no p4's with 4 cores, any p4 out there is slower then what he had, and the p4's that were made in 775 were very small and limited in quantity, to a almost non existant extent. BUT you are right.

You know I think some one tricked the OP. Or OP is on pot/speed, or other illegal drug. Or he's a troll.

I agree, something isnt adding up, either hes naive and was tricked, or just retarded, i guess well never know.

You made my day

He's obviously just a troll.  
Also, there where MANY P4s made in socket 775, maybe you didn't have one back then since most enthusiasts where using Athlons or Opterons at the time.

Maybe i didnt have one cuz my system ran just fine, and compared to actualy 478 p4 sales, there werent many made.

Still, it's stupid to say they where made in very limited quantities when they where made for more than 2 years.

not really, they didnt sell as well as the other socket 775's and when compared to socket 478 i would be suprised if they passed 10% of them also, limited numbers, they were only a holdover. Welcome to reality
