Difference between socket 478 and 478b?

[btcomm1]

I have a motherboard that says it has a socket 478b and is there a difference in heat sinks between that and a 478A or 478? Or is the B probrably just an identifier for the motherboard maker?

I have never heard of such a thing. Google is not very helpful. What make/model is this motherboard?

I've never heard of it either. The pentium4 chips that went into that socket had a suffix like P4b (to identify their FSB) but I never heard of it on the socket itself.

There is no difference. As mentioned is has to do with the designed FSB!

I've been thinking about this one for awhile now, and here's the only two things that I could come up with, that make sense to me. Either that's the motherboard model, or it's some kind of a denotation by the manufacturer of whether or not it supports Preshott's. Now, obviously, the major manufacturers at that time didn't have a model 478b, but that doesn't mean that someone like PCChips, or an OEM manufacturer for Dell or E-machines or the like didn't.

And sure, a motherboard that supports Preshott's should really be a 478E, but I can see them also using B, as in "the first would have been A, if we had known that we were going to have to build Skt. 478 boards with much better caps, for a later revision chip", so we'll call this one the B version. Of course, none of that has anything to do with heatsinks.:laugh: The same heatsink will fit on all Skt. 478 boards.

Gee, I got one of the first i865PE boards out (rev 1) and it supports the then unreleased Prescott.

I can vouch for this as my motherboard socket had the "478b" moniker. It just means the it uses the P4b processor revision. ie. I'm using the P4 2.8Ghz (533 mhz FSB / 512k L2 cache)
