One thing that comes to mind is that the Tualatin P3-1.26 is a server cpu and does not work in many desktop boards (I have *heard* that it requires motherboard/memory ECC). If you've done the checking, and the board is suitable then cool.
It sounds like you're talking about the Pentium III-S. Are you sure the Pentium III-S has specific motherboard and memory requirements? The one I got was advertised as Pentium III, not Pentium III-S, but I'll send an email about that now. Good call. http://en.wikipedia.org/wiki/Pentium_III#Tualatin "Tualatin performed quite well, especially in variations which had 512 KiB L2 cache (called the Pentium III-S). The Pentium III-S variant was mainly intended for servers, especially those where power consumption mattered, i.e., thin blade servers."
I would hunt PC133 memory on ebay
So you think PC-133 should work in a motherboard that only officially supports PC-100?
With respect to the question "yeah - but is it worth upgrading?" - I think there is plenty of life left in PIII machinery
Yeah, I should be able to get a *lot* more power out of my MythTV system (also a wireless router and firewall) with a $31 CPU upgrade and ~$35 memory upgrade. That's just plain worth it. :) Plus, I figure I can start saving the parts I upgrade for another (slower) system. - Grant -- gentoo-user@gentoo.org mailing list
