Most of the ram here ^^^ will work well for overclocking. DDR2 ram is so cheap now, you might as well get the good stuff right from the get go. The best thing to do is run the ram on 2.0 and the timings @ "auto by spd" at first, then get your cpu overclock all set and stable, then go back and see if you can get away with tighter timings. (On this board, you can adjust the ram timings by hitting CTRL and F1 in the main BIOS screen.) This is what I did and it worked out well for me.
*If anyone wishes to correct me on this, feel free, I'm all ears because I'm fairly new at this myself.
Sorry, I am new to overclocking....tighter timings? If my stock timings are 5-6-6-17 what would be tighter? Higher or lower? I'm new to all this jazz....thanks
