What I want to know is, how do you have your B&W running at 500mhz. I've got a 450 server and tried adjusting the jumpers for 500, no dice. No startup, no nothing.
I actually have it running at 550MHz...using an OCC'd XLR8 500MHz G3 CPU. The only way I did this was to buy a low profile Thermaltake heatsink/fan. It is all copper with microfins (like a radiator), it cooled the CPU by 20-30 degrees Celsius in comparison to the stock heatsink/fan (aluminum does not transfer heat nearly as well as copper does). Arctic Silver thermal grease is also very nice, has silver in it to help transfer heat better to the heatsink from the CPU core. I have been told that this particular chip will run at 600MHz if it is kept very cool (I.e. a Peltier cooler or compressed air cooling/water cooler). However, not only do I not want to put water into my computer, but the 50MHz increase in speed isn't worth the time and investment into such a cooling mechanism. Now, I would possibly invest in a Peltier cooler (dropping the CPU temp another 20-30 degrees to around 18-28 degrees over the current 48 degrees) if I knew it would allow me to run the Powerlogix chip at 1000 MHz-1 GHz...if the logic board\memory would take it...I would have to underclock the cache, as the PL CPU runs the cache at full processor clock...that would be cool, I would be the only one I know with a 1000 MHz B&W.
