Hello Im new here and not use to using forums. I can build computers with out much of a problem, but i dont know alot about overclocking. Im wanting to build a new pc for games, with a Gigabyte GA-EP45-UD3P revision 1.1 mother board, CORE 2 Quad Q9300 FSB of 1333mhz, now here is what i dont know. I read this some where ( Core 2 technology benefits from RAM running synchronously with the FSB 1:1) if this is true I need memory at 667mhz to work the best . now i have 4-1 gig sticks of Gskill of ddr2 at 800mhz will it work just as well to down clock it to 667mhz? And I will run three os systems on the computer 2000,xp 32, win 7 64, not sure if i will use 2000 I would like to over clock the proccesor to 3ghz. I might upgrade the proccesor later on to somthing arround Q9550, and wanted to use 4-2 gigs sticks of ram for win 7, would 800 mhz memory work fine or should use 1066 down clocked (for a wider range of overclocking on the cpu with out going over 1066 on memory) ? I will do some overclocking-not a lot at first, at least till I get a better understandig of overclocking. I currently have the mother board, processor, the memory, and a copy of xp-32 pro to build my new system. Any info would be great Thanks for any help I can get
