T2390 CPU in T43p?

[lukee]

Hello, I got a chance to buy Intel Core Duo CPU 1.83GHz. Can it work in T43p? I've performed comparsion of the current CPU (P-M 770) with this T2390 and major parameters seem to be same for both:

FSB: 533 MHz
Package size: 35 x 35 mm
Socket type: PPGA478

Here is detailed comparsion of both CPUs:

Only thing where I have a concerns would be chipset/BIOS incompatibility

It'll fit, but won't work.

Thanks Fred.

It'll fit, but won't work.

Just curious, while it shouldn't work on paper, has anyone tried it?

The chipset in T43/p does not support dual cores...end of story.

[Bibin]

Understood, but a lot of technical documents claim things do not support them when in fact at the time of writing the unsupported thing had not yet been conceptualized... My old P965-equipped desktop computer is not supposed to recognize LGA775 CPUs with a 1333mhz FSB, yet it does.

Desktops are - and have ALWAYS been - far more upgradeable than laptops...

Ok, sure, but the point still stands. I have an old PowerBook G3 where the max ram is 384MB - it happily will accept 512MB without any limitations.

While it's not supposed to be supported it would be an interesting thing to try for the sake of trying. Hell, if I get my hands on the CPU I'll put it in myself.

Even if the chip set compatibility wasn't an issue, the T2390 has a completely different pinout to the Pentium M.
