I have an antiquated Sony Vaio PCG-K23 that's about to undergo
"surgery" to replace the ailing cooling unit. But I figured while I
had it open, I might update the CPU to something a bit more power
friendly, or at least not quite the heat monster. I was able to get
the parts list enough to see there's currently a SL6PF Intel P4 in
there with a ATI RS200MP chipset (which had little info on which CPUs
it supported). But I can't tell what my CPU options are. Any ideas?
Thanks.

The only way to know for sure is to find out from Sony. However it's my
experience that Pentium 4 (M) motherboards will only take P4 (or P4-based
Celeron) CPUs. I skipped the abimination that was P4 myself and went from P3
to Pentium M.

You're probably best off selling it to someone who buys by numbers (GHz) and
replacing it with a Pentium M machine IMO.

From what I can tell, that is a desktop, not a laptop, CPU. Since it's
near the top of the speed range already, you may not be able to do much
at all in terms of an upgrade.

Heh! That'll teach me to not do the research.. Still, the answer's the same,
find out from Sony.

You're right from what I can tell. It's an old Northwood PGA desktop CPU so
there's little to no chance of an upgrade as the only thing that might
possibly work in there is a PrescHOT and you wouldn't want that!

If it were mine I'd be looking to downgrade the speed and upgrade the L2.
(Actually I'd be looking for a buyer.)

Oh, I Googled Sony Vaio PCG-K23 CPU upgrade yesterday and saw that the OP's
asked on a few forums as well (unless they're all just leeching usenet) but
I didn't see much in the way of replies.

Yeah, I finally had to crack the hood to swap out the fan unit. It's
an SL6PF
processor (2.8GHz, 533FSB, 130nm, 512kB L2, Socket 478). If the ATI
chipset
could handle 90nm, I might be able to slide into something with 1MB
L2, but
I can't seem to find anything definite about what the chipset can
handle.

And I'd LOVE to toss this thing entirely and go with the latest &
greatest,
but alas, times are tough and I have to make due... :-\
