Leading up to apt-GTX580! HD7970-AMD,7970 overclocking experience, overclocking, 1.26GHz,6.9GHz, three screens
Radeon HD 7970 technology, performance, power consumption is very good, overclocking is the number one players, but now because of the lack of tools, but not very casually over too high. HardOCP recently did a special test, the Radeon HD 7970 for a more in-depth overclocking experience, the highest over to 1.26/6.9GHz, and had Eyefinity three-screen game testing.
How to overclock Radeon HD 7970 []
A card overclocking is by far the most convenient Catalyst Control Center OverDrive feature, you can directly drag the slider, but may be in order to ensure absolute safety, AMD has done a lot of limitations, core / memory frequency could only mention 1125/6300MHz, only higher than the original frequency 200/800MHz, obviously not fun.
Most third-party overclocking tools so that only MSI has just updated Afterburner can theoretically over after the break through to 1390/7160MHz, the actual test that can be pressurized to 1.3V to the core 1.2GHz ultra above.
Sapphire also provides an internal test version of the TRIXX Utility, can also unlock the Radeon HD 7970's overclocking limits. Through repeated testing, the final voltage to 1.3V, the core overclocked to 1260MHz, memory overclocked to 6900MHz, very stable!
Manual fan speed is fixed at the same time 75%, is quite noisy. The bottom of the power control settings both down-energy, to ensure the stability of the effect of overclocking, the overclocking can be pulled right +20%, thereby increasing control TDP.
