Dell OptiPlex 760 ultra small form factor possible to add ddr3 ram to it?

Hi everyone,

I have an old OptiPlex 760 ultra small form factor and I just installed windows 10 which runs smooth most of the time.

This OptiPlex 760 has an Intel Core Duo E8600 CPU in it. I have been googling and if I understand correcty ,this CPU supports both ddr2 and ddr3 ram. Does this mean that I can put ddr3 ram in this machine?

Also I wonder if I can add more than 4gb of ram to it. I know that officially it says max supported ram is 4gb but if I look at my MacBook it says max supported ram is 8 gb and I have 16gb in it.

So I wonder if this is the same case with my OptiPlex.

Thanks.
