This question gets a little complicated... Having seen multiple fried vid cards I now recommend against overclocking them, BUT... I was just reading the posts on running the barton 333 with my MB (giga 7VRXP http://mysite.freeserve.com/hoodspages/fifth_divider.htm) and the gyrations required to get the 7VRXP to run with a Barton at 333 got me thinking. Basically with the VRXP you end up with 2xFSB as the AGP speed which, when trying to run a Barton at 333 FSB, means the AGP clock goes to 333 also. But, since I have the 8X AGP Radeon 9500 PRO it can handle higher than the 4x AGP = 266 mhz. This would appear to not be overclocking the Vid Card? The questions: Will there be other effects on the AGP interface timing even though clock is in spec for 8x? Are the Video "on board" mem and GPU clocks independent of the AGP clock? It looks like yes from what I can tell. I have some 333 memory so if I OC the MB to a Barton FSB I can run synchronous at 333 (mem, fsb, vid). This has some interesting possibilities for a peformance boost by just going to a $95 Barton XP 2500 (even before overclcoking the multiplier). Anybody see any loopholes in this? I'd add a fan to the chipset cooler as a precaution. Old Vid card coolers (courtesy of the above mentioned fried vid cards) and a piece of double sided heat sink tape work nicely.
