Hi all,

I've been going through testing all my old processors including a bunch of socket 478 Pentium 4s.

I also have these (see pictures) some of which appear to have the same pin grid as the socket 478 but some of which are slightly different, I think they may be laptop CPUs.

The one on the left is a Northwood 3.0GHz just for reference, which does work in my 478 motherboard.

So is it safe to try the others and are they likely to work?

Phill.
