I have 512MB pc3500ddr cas2.5 ram. I have heard good things about this ram so I figured i'd be able to hit a good overclock with this. I am at a 170Mhz FSB on an abit kx7-333r. My cpu is n axp1600 agioa y at 1.8Ghz and my voltage settings are 1.85v core, 3.65v I/O Voltage, and 2.85v ram. My memory timmings are cas2.5, 2, 5, 2 and 2T. I can't seem to get my ram any higher though. If I lower my I/O voltage to 2.5(default) my system is unstable. I am not sure if its because my cpu is maxed out or if its the ram. Anyone have any ideas? I just think that ddr433 ram should be able to run at cas2 and 2,5,2,1T timmings at 340Mhz. I can't increase my voltages anymore.Also would burning in my ram help? If so how would I do that.
