So im installing W7 64 Bit because im upgrading my ram,current ram is OCZ 1gb x2 @ 5-5-5-15 @ 2.1 Volts. @ 1066. Im going to order another 4gb (Total of 6gb of RAM),Do i need to get the same RAM Timings as to what i already have OR will me existing ram just underclock itself to meet the timings of the new RAM?
