Quick question about socket 775 mobos (my knowledge is outdated - help bring me up to speed!)

[jstamm1091]

I see most socket 775 mobos say they are C2D, Pentium D, Pentium 4 compatible. Does P4 compatible mean it will also run 478 chips?? Or did they make P4s for 775? I thought 775 came out after they stopped making the P4...

So, I'm pretty confused here. Please help me out.

Thanks in advance,
Jeff

no, a P4 that is a used in a 478 socket wont work on a 775 board. Most of the P4 775's are around 3ghz with the hyper threading but P4 is old school now everyone will tell you that core2duo is the way to go.

Im currently running on a P4 2.8 prescott 478 and im upgrading to 775 and core2duo

Like Sorry said, P4 is 478, which will not work with a 775 board. I think the confusion comes in that Intel labeled the Dual core E21xx series processors Pentium. They are dual core processors, but called pentium.

No

Or did they make P4s for 775?

Yes. Northwood P4s = 478, Prescott and Smithfield (dual core) P4s = 775

I thought 775 came out after they stopped making the P4...

No (see above)

Pentium 4 Prescott was available on both Socket 478 and Socket 775 (aka Socket T). Smithfield was a Pentium D. Pentium 4 Cedar Mill came after Prescott, and was exclusive to Socket 775. More here. In short, Intel was still very much selling the Pentium 4 when they introduced Socket 775.


There is no compatibility between Socket 478 and 775 processors and motherboards, period.

They should have made an adapter 😉
that reroutes the pins and ends them with tiny balls or w\e is on the bottom of the 775 cpus
