Today appeared the methods of hardware modification of Radeon HD 7970 power system, which allows to conquer with proper cooling the boundary of 1600 MHz on the core.
In overclocking environment, the term OCP mod means the modification of power system, which allows to bypass the protection against over-voltage. The purpose of modification - to increase the range of voltages to the processor core . Since the implementation of this modification involves work in the modes associated with increased heat, usually the idea is considered in conjunction with an efficient cooling - for example, with the help of liquid nitrogen.
Greek enthusiasts show where you need to solder the 47k resistor .
If using liquid nitrogen the Radeon HD 7970 work only on the core frequency 1550 MHz, after modification the core frequency can be increased up to 1620 MHz . Memory was overclocked to 7600 MHz QDR. This allowed to collect 14,275 points in 3DMark'11 Performance paired with overclocked six-core processor Core i7-3960X ( 5314 MHz ).
This result is only the third in the ranking of Radeon HD 7970 overclocking version of HWBot. In the first place Andre Yang at 1700/8000 MHz frequencies and the result of 15 063 points in 3DMark'11 Performance . He was able to overclock the CPU to 5637 MHz. Related Products :
