Alright, so I ordered a 2x512mb pair of ram for my computer because my current stuff is junk. The ram I ordered is DDR 400, but in my motherboard manual its telling me that it by default sets it to 333 if its 400 (thats what it says in the Specifications of my motherboard, doesnt state Mhz or not). What confuses me is why does my motherboard set it to 333 by default? Also, if I change it from auto, would I also have to change the CPU bus to match? If I do set it to 400 would it in anyway be able to damage my motherboard or something? In my manual it says "Note: If you use 400 MHz memory module, the default data of this motherboard will run the efficiency of 333 Mhz." This is what adds to my confusion, in the bios it states "DRam Frequency - Allows you to set the DDR operating frequency. If you select [Auto] the motherboard will detect memory modules and assigns appropriate frequency automatically. Config options: [Auto] [133 Mhz (DDR266)] [166 Mhz (DDR333)] [200 Mhz (DDR 400)]" Now this is where I'm totally blown away, is there a DDR 800 that for some reason I never heard of that clocks at 400 Mhz but since the motherboard cant support it, it goes to 333 Mhz? Or is it what I think it is, the DDR 400 will clock to DDR 333?
I haven't gotten the ram yet, I just ordered it recently. I thought I'd post this now though, so that when I do get my ram and it doesn't go to 400 by default ( 200 Mhz ) and goes to 333 (166 Mhz) should I set it to 400 manually?
