Sapphire ATI 9800 Pro Ultimate 128 Mb
Posted on 2004-08-26
having recently bought the above card i couldnt help to stop thinking of overclocking it
as i eventually did and to my surprise the limits of this card were not as sky-high as i expected
as you know the default clock is 380/340 on core and ram respectively, which is actually 680 on ram as it is DDR
utility used was the radlinker, current driver Catalyst 4.2 - the last ones if im not mistaken
3dMark2003 on default clocks has measured a 5641 points
having overclocked the card to 420/380, which is a fairly small overclock considering the abilities of the card, well beyond that the card prodused artifacts. with the new clock the score went up to 6129 (+/- 20 points)
the card is water cooled, along with the processor using a cusomised Thermaltake Aquarius 2 Kit and WaterChill VGA water block
there is no temp probe on the card itlesf, thus i cant actually say what temps it is running at, but the temp of the processor hardly goes over the 40C mark, usually stays at 27-35C, well unless i play Far Cry all day.
having said that
it is a fast, quality card which is supposed to be overclocked by at least 100mhz on the core and i would expect 80mhz on the ram, with a decent water cooling and yet it doesnt let me tweak it as i wish
ive seen other people manage to overclock it to the amazing 500-520 mhz on the core and 420-450 on the ram
why cant i???"?"!?!?!
as well as overclocking i am very curious about modding the card, is there any mods that could increase the performance? now i know that X800 pro can be modded to X800XT by a simple connection of 2 pins on the chipset, increasing from 12 to 16 pipelines
can this be done with 9800 pro chipset too? if yes how?
or maybe there is a voltage mod available to it? if yes how to do it?
