Selecting a very high memory frequency may cause the system to become unstable! If this happens, revert to the default setting. OC Tuner Allows you to select the mode of OC Tuner. OC Tuner automatically overlocks the CPU or DRAM frequencies and voltage for an enhanced system performance depending on the DRAM type and an accelerated iGPU performance depending on the iGPU loading. Install an effecient CPU fan for OC Tunder I or Tunder II mode selection.
