"To reach DDR3 1866MHz or above, you must install two memory modules and install them in the DDR3_3 and DDR3_4 memory sockets" jerry6 January 21, 2011 3:05:55 PM I thought the rev 2.1 board could run @ 2000 . I just want to put in another 8 Gb fill up the slots , I use Gskill F-3 1280 cl9 , 1600 is enough , just want to be sure it works before I buy So 1866 will not work on 4 slots ?
