Upgarade ML350G6 to Xeon X5672

Hi

I´m about to upgrade an ML350 G6.

I would like to install a Xeon X5672 (3.2 Ghz), replacing a Xeon E5606 (2.13 Ghz)

Could anyone recommend, which modules of ram tu use to obtain 16GB.
No special configuration is necessary.

I´m willing to discard the 4GB module currently installed, should it be necessary.

Is it going to be necessary to change anything manually in the BIOS, to do all of this?

Thanx.

M.P
