    Can you mix memory chip makers? (2 SODIMMS)

    My laptop came back from repair (dead no power-new system board and LCD) and now it either blue screens, re-boots, or locks up (even when just turned on so its not heat related).

    HP sent me 2 memory sticks (1GB). One Samsung and the other made by some unknown vendor. The laptop runs fine with only one stick, but putting these two in has caused problems.

    My Case Manager claims its because the 2 SODIMMS are from different makers and is sending me more memory. I think I have a defective system board.

    Do you agree with HP or me?

    It should work just fine, though some laptops don't like sticks with different speeds and CAS ratings.

    HP qualifies vendors prior to using SO-DIMMS. Two parts that meet HP specs should always work together. (most parts will work together no matter what).

    If they really came from HP - that is almost certainly not the problem.

    Does it work with either stick? In either slot? One might just be bad.

    So far its seems that whenever there is a chip in the second slot there is a problem. I have tried using the stick I know to be good with either one of the new 2 from HP and always the same issue.

    Yes, I know they 'should work,' but they don't. I'm still leaning towards defective system board, but I have to wait until Monday night since HP is sure its the mixed SODIMMS.

    Mixing memory can occasionally cause issues. I've never experienced these issues myself, but I have heard of people who have had problems mixing different brands of memory together.

    Nearly all RAM these days complies with the JEDEC standards. Mixing ram shouldnt is not a problem

    Sounds like one of your ram is faulty or corrupted. I suggest running memtest86+ for a few hours.
