MSI Z97 PLATFORM OC SETTING
REFERENCE TABLE
Note:
The reference value above is for Core i7-4770K ES Processor.
Increasing voltage may raise the success rate of overclocking as the risk of damage the
CPU; thus,we suggest use the special design CPU cooler set to prevent the CPU from
overheating.
Below voltage value would cause the damage of component while under air cooling.
* CPU Voltage:1.6V
* CPU Ring Voltage: < Vcore Voltage
* DRAM Voltage:1.9V
We suggest disable some item in BIOS,such as Phase Control and OverSpeed Protection ,
but EIST、Turbo Boost
If you disable OVP、OCP Function, motherboard or CPU might be damaged.
