Some links with info you may find useful. Note the section on Compatibility Package.
> http://www.cpu-world...(mPGA478B).html
According to this chart, you CPU is not supported, first that does support is Socket 479 / mPGA479M > http://www.cpu-world...0537GG041F.html
If this is your CPU, it is socket P > http://www.cpu-world...0537GG041F.html

There are four different names from HP which might effect what CPU is supported.

P4sd-la yale motherboard . it say the chipset i865pe is supported . The processer is a ppga478 and my motherboard say mpga478b . but I don't understand how people have mpga478b with this same core working.

So what is the difference between the both ppga478 and mpga478 .

Gday.
Sorry that info given is only what I can gleam of the WEB as I am not an engineer.
My understanding is that the sockets are all the same layout except with suffex © at the end which supports Core 2 Duo (socket 478/479). The function of the arays are slightly different on each type, chipset support, functions of the CPU like security and TDP, total power draw, ie, board supporting mobile CPU, may only be 25w, CPU Desktop may be 85w +. So installing a desktop CPU on a board meant for Mobile CPU will not work
The BOIS ver. also plays a part in which CPU can be supported..
.
If this is your MB. > http://h10025.www1.h...cname=c00041640
My best guess is that any CPU on this list will work except, not at all sure of the Extreme, I would also not go higher than 3.2GHz. Take note of what BIOS ver, you need for the CPU selected.
The Celeron/Celeron D do not support hyper threading.

This is how I see the situation. The only way you can get concrete confirmation is to contact HP support.


Your MB does not support Core 2 Due, even with a BIOS update. The socket on your MB is mPGA478, only a MB with socket mPGA478C supports the Core 2 Duo.
The sockets look identical but the socket on your MB has physical parts inside that are not connected.
