DRAM O.C. Profile [DDR3-1600MHz]
This item appears only when you set the Ai Overclock Tuner item to [D.O.C.P.] and allows
you to select a DRAM O.C. profile, which applies different settings to DRAM frequency,
DRAM timing and DRAM voltage. Configuration options: [DDR3-1600MHz] [DDR3-1800MHz]
[DDR3-1866MHz] [DDR3-2000MHz]
Profile Info : xxxxMHz–x-x-x-xx
This item appears only when you set the Ai Overclock Tuner item to [D.O.C.P.] and displays
the current DRAM profile information. The profile information varies according to the DRAM
O.C. Profile you’ve selected.
