Overclocked to 4500MHz

Ai Tweaker Settings:

Ai Overclock Tuner D.O.C.P.
DRAM O.C. Profile Profile #0
CPU ratio 22.5
Turbo core DISABLED
CPU Bus Freq. 200 (default)
PCIE Freq. 100 (default)
Memory Freq DDR3-1600 (default)
CPU/NB Freq: 2600MHz
HT Link Speed: 2400MHz

CPU Spread Spectrum: auto
PCIe Spread Spectrum: auto
EPU: Disabled

CPU Offset Voltage: 1.320V     +0.075000
