socket 478 400mhz cpu upgrades

Hello,

I've read somewhere that intel makes a socket 478 version of the core duo. Would this work on my old socket 478 400mhz fsb intel hv84510a motherboard? Might it work at a lower clock speed? I have a ton of ram on this machine and i would like to see just how much it can be upgraded.

It's really a socket 479 and it is not pin-compatible with the Pentium-M or siblings: http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2627.  It requires a completely new board and chipset.

Actually Intel lists 3 core duo processors with socket 478-what Callandor refers to on his link is that the Pentium M is a socket 479.

But I don't think your board is compatible with these type processor due to the 2MB cache and the 667 mhz FSB required to run it. The Mobile Intel® 945 Express Chipset Family motherboards are compatible with this CPU and are only found in laptops.( since you have posted in desktops I assume this is important to you)
The hv84510a is old technology and won't run this processor.

You have an Intel D845HV motherboard in that.
(Also called "El Paso" in some places. Do not confuse it with "El Paso 2".)

Here is your supported processors list:

Max is a 2.6 GHz P4 with 512k cache on a 400 MHz FSB.

Big "oops" on my part - I was indeed looking at the Pentium-M successor.  Thanks for the correction, sparkmaker!

I actually was interested in the link you posted stating the 479 pin. Even before I read the article I didn't know the pentium m cpus were of that persuasion, so I learned something too  :-)
