Gainward GTX 560 Ti Phantom 1GB tested - 9. Overclocking, Thermals, Noise

Review: Powerful and Silent


Overclocking

Overclocking the GF114 should not be a problem, regardless of whether it’s reference or specially designed GTX 560 Ti. Most GTX 560 cards will run stable at 920+MHz. Gainward’s cooling provides a nice foundation for a healthy overclock and we got to following results. We managed to push the GPU from 835MHz to 930MHz, and the card remained quiet throughout.

Thermals and Noise

As far as noise levels go, the GTX 560 Phantom’s cooler is almost inaudible when idle, with GPU temperature around 33°C. The GTX 560 Phantom is almost inaudible during operation too. In our case, intensive 3D resulted in GPU temperature of about 73°C.

Consumption

Nvidia Geforce GTX 560 Ti provides nice performance, on many occasions comparable to those of the HD 6950 2GB. While AMD’s HD 6950 consumes about 20W less during gaming, the GTX 560 Ti consumes some 4W less when both cards are idle.

Nvidia added Advanced Power Management on all cards in the GTX 500 series, a feature which monitors consumption and performs power capping – all to protect the graphics cards from excessive power draw and potential damage. When the sensors detect higher than allowed consumption, the GTX 560 automatically downclocks and reverts to original clocks when the overcurrent is over.

GTX 560 Phantom 1GB’s GPU runs at 835MHz; the shaders are at 1670MHz whereas the memory runs at 4100MHz. When idle, the card downclocks to 50.6MHz for the GPU, 101MHz for shaders and 135MHz for the memory.
