    I have 1Gb of ram in the form of 2 sticks of 512Mb.

    I'd like to add another gig, was wondering if I can add a 1Gb stick or do I need to go with 2x512.

    I have full spec info on my existing ram sticks in-hand, so could match timing and whatnot.

    I read a review on NewEgg (exact same brand/specs as 512 sticks I'm already using) where purchaser said these were "double-sided" and using 4x512 slowed the speed from spec 400MHz to 333MHz. Post said "don't be a dummy like me, just get 2x1Gb instead."

    I didn't really understand the part about "double-sided", but did get the "slower" part LOL.

    Does this make sense to anyone? i.e. 4x512Mb would be slower than expected?

    If the answer to my original question is No, you can't use a 1Gb stick with 2x512Mb sticks, would you then recommend discarding the 512s and just getting 2x1Gb as suggested? (would rather not due to financial constraints)

    Thx smart people!

    Short answer: yes

    Long answer:
    There is a good chance that in the near future you will start to have issues with your computer as a result of using different sticks of ram together. It's always best to use the same brand and capacity ram.

    OK thanks - better safe than sorry I just ordered 2 more sticks of 512Mb.

    Oh and FYI for anyone looking for similar info, another smart person suggested the reason the speed dropped from 400MHz to 333MHz was that the new pair was operating at the slower speed, so the Bios just dropped the others to match.
