If I have 256 ram 2700 and for instance I find some on sale but it is 512 ram 3200. Can I pull the 2700 and replace with the new ram?

Hehe yeah, 768MB of PC2700 is arguably better than 512MB of PC3200 ... although for gaming its fairly close (personally id prolly go for the 512 setup)i would just keep both sticks of ram in!
Actually yes it will (provided it physically fits ... if it doesnt we dont need to bother replying hehe)Motherboard will underclock it?? Not really... since all motherboards and pcs are different, if a new memory stick is put into a old system it could possibly damage the system internal componants.
