ATI Radeon X1900XTX - Performance and overclocking - Overclocking: Water cooling

We set up a water cooling system, consisting of a Danger Den water block, 3x120mm radiator and an Eheim 1250 pump. The radiator was placed at an open window, and then we waited for the temperature to drop before we began overclocking. +3.3 degrees centigrade was the lowest value we received, which made us begin.

The memory was cooled with a large fan using cool air, but wouldn't go further than before, 900 MHz. The core clocked nicely with lots of chill, and we succeeded in completing occasional tests at 796 MHz, but for a whole round of tests, we were forced to go down to 790 MHz. Thanks to the colder air, we also managed to clock the processor a bit more. 13497 points was the final result and in spite of numerous tries, 13500 points wouldn't work with us on this occasion.
