Problem with 4GB(2x2GB) RAM in ASUS P5KPL

Hello
i have just installed 2x2Gb kingston RAM on my board but when i turn the pc on, windows boots and only several seconds after booting it restarts. what could be the problem?
before this, i had 2x1 GB RAM and it worked nice, with no problem.
by the way, my OS is windows 7

  1. I think the one of the RAM is not fine..
    Check each RAM one by one...
  2. If the RAM is approved for your CPU, then run Memtest86+ from a floppy, CD or flash drive to check each DIMM for errors - individually and then with both installed.

    Your mobo has "800/667 mhz for RAM" so go into the bios to reduce the memory frequency in bios to 667MHz down from 800MHz..try this...
    And please check that what is the ram speed..

    Also check with different combos, like...
    "Put 1st RAM i.e. the old one in 1st slot and other in 3rd slot."

    i found the problem: the M.B. just suuports RAMs with cl5 while the one i bought is cl6. i tried changing the frequency and many other things, but they don't work!

    THANX anyway
