POSTER: computer news   ||   R600 RADEON HD 2900 XT UNDER LIQUID NITROGEN EXTREME OVERCLOCKING	DATE:2007-05-16
Usually the use of liquid nitrogen to cool hardware components result in reaching the maxim possible of processor or video chip frequencies  . The Released on this week 80 nm video chip r600 using different cooling systems proved that for good overclock it is necessary no have strong cooling system . Under Freon at temperature approximately -90 degree Celsius r600 video chip was overclocked to 1150 MHz with 1.45 v voltage .   Now, the video chip was coupled with copper liquid nitrogen container  , the corresponding substance with boiling point at - 196 degree Celsius was placed in the container, video chip voltage was increased to 1.53 v. The radeon HD 2900 XT was overclocked to 1230 MHz. Increase in frequency composed 65,5%, yes even in the absolute value this frequency is phenomenal. However, container with liquid nitrogen after some minutes was hot about - 70 degree Celsius , and this is alarming sign for similar experiments . Associates came to the conclusion that even liquid nitrogen cannot cool R600 so effectively ;-). It is assumed that 80 nm chip r600 suffers from high leakages values , which lead to an increase in the heat emission and energy consumption. From the similar problems in their time suffered 90 nm processors intel core prescott. Back to the overclock results Of radeon HD 2900 XT to 1211 MHz in the chip and 2000 MHz DDR in the memory, this card achieved a new record in 3DMark'03 - system on base of dual core processor core 2 Extreme x6800 (3.7 GHz) collected 54 215 points. Further processor overclock can improve the general result.... Related Products :
