I built a nearly identical system for a friend though he has the ATI 9800 AIW. Both cpus can clock easily to 225MHz bus but at this point I have to turn the ram down from Streetracer to normal. At 220MHz I can run in turbo. The biggest question I have is how in the heck can I get the machine to run the AGP bus to run higher than 66MHz? I know 'how' to do it, it's just that the system won't boot. This is a new one to me as it has always been really easy to get the AGP/PCI bus to clock considerbaly higher, even on crappy hardware. This holds true when the system is barely clocked at all (205MHz). Any sage advice or general tips for this board would be nice. Thanks!
Typically you don't want to be running the AGP bus, and more importantly PCI, beyond 66MHz/33MHz range - ATI's are especially picky about this any more. Some folks have gotten away with around 72MHz, but that is in some extreme overclocking (300MHz +) with a huge array of voltage mods and mosfet cooling changes . Anything beyond 69Mhz though is just asking for instability and other issues. The MAXII's are known to undervolt on AGP, so it may help bumping that up to like 1.6V.
To get any decent overclocks on memory, you'll have to turn off the GAT options and hardset them, along with memory timings. I know on the GAT, first three of mine are set to AUTO, and the last two are Disabled. With your PC3500 memory, I would think you'd be able to run 1:1 to around the 230-240MHz mark, not 100% though, I've only worked with PC3200 and PC4000+ so I'm not sure where a 3500's "max limit" is before you'd have to start using a 3:2 or 5:4 divider.
