I am wondering how many of you have experience overclocking ATI cards.
I have an X1300 Pro AGP, and have noticed some abnormal things when I use ATITool. Sitting idle at my desktop it is showing 65-66*C GPU temp, when I use the 3D simulation this rapidly climbs to 75-ish*C (72-78). If I overclock it at all, the temp climbs even further, up well into the 80's (85-88*C). What is strange is that when it reaches these temperatures, there is no failure, and the fan speed remains low (given as a percentage, but it has only gone as high as 39%). There are no artifacts at all, and this just doesn't seem right to me.
The stock core and memory speeds are 600/400 respectively, and I have turned it up to roughly 675/475 with only the above temperature differences to note.
If I turn it up over 700/500 my computer blue screens immediately, so I know I am near the limit. I don't keep the card running at those speeds, it was more of a curiousity thing that caused me to turn it up in the first place.
If it is relevant at all, the rest of the specs are as follows: ASRock Intel 865i chipset board, p4 2.4GHz non-HT (running 2.71GHz), 1GB DDR-266 SDRAM (2x512mb, at 300MHz since the FSB ratio is locked). Also worth noting the system is running vista ultimate. The readings above occured with the processor/memory running at normal speed and overclocked.
Could those temps be accurate? How can a card run so hot, and still be stable?
The memory temps never topped 55*C throughout the process.
I am not looking for a ton of advice on overclocking, I have found my optimum settings already, and they are 625/437.5, anything above that and I gain nothing.
