With the near r600 announcement , AMD become clear in the power requirement of this card. The need to use a combination of six-pin and octal connector is required.
Associates conducted the necessary work. If user do not attach the octal power connector, after connecting the video card Radeon HD 2900 XT to two six-pin power connector , then overdrive function will become inaccessible in drivers and video chip monitoring temperature will just disappear . Catalyst drivers are instruments to control the frequencies and temperature. If video card understands, that the octal power is not connected, the entire frequencies and temperature control is blocked.
The second story concerns the power unit. Official AMD documents call the digit not less than 750 W, but producer have another values. The energy consumption of two video card radeon HD 2900 XT, which work in crossFire mode is similar to powerful four core processor. But if we talk about one video card then the power used will be similar to dual cores processor, Radeon HD 2900 XT can completely work with qualitative power unit with power 400 W. This was checked by our associates in practice.
In a word, if you plan to purchase radeon HD 2900 XT , there is no need to update your power units. :-) Related Products :
