Questions about this item

Should I choose the 2.26 GHz Core 2 Duo version or a different CPU speed for my Latitude E4300?

This motherboard has the 2.26 GHz Intel 45nm Core 2 Duo processor soldered on board, so the clock speed is fixed and not selectable.

What does the 2.26 GHz figure mean once the board is installed in a real machine?

The 2.26 GHz rating is the base clock of the on-board SP9300 Core 2 Duo; actual performance depends on the laptop's cooling, DDR3 memory speed and the workload you run.

Which interface standard does the board use and what does it cap in practice?

The board uses DDR3 SDRAM slots; the memory controller on the 45nm Core 2 Duo caps the maximum supported RAM speed to the DDR3 standard supported by that processor.
