    Hi, can someone help me with a RAM query please,

    I've got a gig of ram in my pc:
    OCZ DDR PC-3200 Premier Dual Channel
    2 x 512MB, 400 MHz CL 2.5-3-3-7, 2.6 volts, 184 Pin Dimm, Unbuffered
    This is it here:
    OCZ Technology | Products | Memory | OCZ DDR PC-3200 Premier Dual ChannelOCZ Technology | Products | Memory | OCZ DDR PC-3200 Premier Dual Channel

    The motherboard is an Asus A8N-E that can take up to 4GB

    I want to put in another GB and having looked at the crucial checker it recommends sticks
    with various specs:

    DDR PC3200 • CL=3 • UNBUFFERED • NON-ECC • DDR400 • 2.6V
    DDR PC3200 • 2-2-2-6 • UNBUFFERED • NON-ECC • DDR400 • 2.8V
    DDR PC4000 • 2.5-4-4-8 • UNBUFFERED • NON-ECC • DDR500 • 2.8V

    My question is....
    What should I go for? Any of these?
    The first one here is CL3, my current memory is CL2.5, but the voltage is 2.6V the same as my memory. If I install it then my current memory will run at CL3 the slower speed – this I don’t really want but it’s correct voltage.

    The next one is CL2-2-2-6 but 2.8V – would this chip run at the slower speed of CL2.5?
    And what about the voltage? Can I mix chips that require 2.6 with 2.8?

    The third is obviously a DDR500 chip – but is CL 2.5. If It’s run at 2.6V would it underclock to 400Mhz and would the CL2.5 stay the same?

    I should really just buy another set of the same sticks I have in – but they are out of stock everywhere I look…

    Help!!

    Thanks.

    Martin
