2x256mb has its uses and 2x512mb has it uses depending what I run. I really wish I could stick with just 2x512mb for everything but it just doesnt clock high enough. Maybe when OCz or some other company makes really good 2x512mb ram that can do ddr600+ at 2.5-3-3-x I will sell all my tccd and buy just that ram. what bios setting change? all I would need to do is lower my fsb for my 2x512. I wont have to swap often, maybe twice a month, id stick to all the games that like 2x512 then when I swap, I play all the games that dont need more than 2x256 ram, back and forth twice a month. as for my winchester thread, I have said plenty, it was getting heated with flames so I didnt bother. some even went as far to refuse to believe I had a winchester so I said forget it, they are too stubbon.
