Hello, my 512mb HyperX PC3500 was running great in the 8RDA+ at 200mhz FSB with 2-2-2-6 timings. So I thought I would buy a matching stick to run in dual. Well My board does not seem to like running in dual at 200mhz FSB. I even changed the timings to default and tried to run at 190 FSB and still would crash. Is there something else I need to do to get this to run in dual and run at 200? Do I just have to live with a much lower FSB to run in dual channel? Thanks for any advice!
