  1. Whats your mobo?

    And your windows? Is it x64bit?
  2. This may help you with what you're after. It deals mostly with RAM timings, but explains Mhz and it's importance in the first page of the tutorial.

  3. ddr2 max speed is 800mhz i think, so yeah higher MHz definitely better.
  4. Iif u have 400MHz, and u get 800MHz, it will be knocked down to 400MHz anyway.

    That is why I asked for the mobo, as it may be cheaper to get more RAM.

    but on cpu id software it is written that ,"Max Bandwith PC2-6400 (400 Mhz)". why is it written ? is it means that i can buy only 2gb 400 mhz ram?
  16. Sometimes when u mix the RAM, it doesn't exactly work.

    So its up to you : )

    Don't know, but it is compatible with

    Supported DIMM types:
    PC2-5300 (667 MHz)
    PC2-6400 (800 MHz)
    Non-ECC memory only, unbuffered
    Supports 2GB DDR2 DIMMs
    Supports up to 4 GB* on 32 bit PCs

  18. 6400 is 800mhz, I assume CPU-z is simpy taking the value from a single lane (there are 2 for DDR2/DDR3, so it would be 2 lanes = 400mhz (per lane) times 2 (amount of lanes) = 800)
