Core 2 Duo E7600 Compatible?

[Theevenger]

I'm currently running an old Dell XPS 400 with a Pentium D 820 (2.8 Ghz). I would like to upgrade to a core 2 duo e7600 as it is the best core 2 duo that runs at my maximum FSB supported (1066 mhz). I am having trouble figuring out if this processor will work in my motherboard due to the 45 nm technology.

Anyway, my stats:
oyc523 mainboard (dell proprietary)
Pentium D 820 (2.8 Ghz, LGA 775, 95 nm, 800 mhz FSB)
northbridge i945p
Dell bios revision a07 (maximum bios version supported by my mainboard)

Any help would be appreciated.

Contact Dell concerning supported processors. You probably won't like the answer.
