    RAM Question

    How do I know what RAM MHz my motherboard is compatible with? I've looked through CPU-Z and can't for the life of me understand all those numbers... lol

    Any help? :)

    The motherboard I got is from a prebuilt computer and came with pretty slow RAM, so I would like to know before I go and buy 2 GB that still goes as slow as the old RAM.

    i'm going to use my super secret powers to send forth my tech alter-ego and examine your PC remotely to determine your specifications...

    AHHHH. FIREWALL!!!! YOU BURNED MY D**N FOOT, YOU ****! :dead:

    sorry, couldn't help myself.

    cpu-z, iirc, reports your ram at double (DDR) it's operating mhz, before quad-pumping. erego, 200mhz is really 800, and 133 is really 533, etc. i could be wrong--been a bit since i played with cpu-z. you could simply go into the bios and see what the speed is, or if you have fast eyes, it should flash mem/proc speed on boot.

    alternatively, google the make/model of the pc you pulled the mobo from, and look up it's technical specifications. you might get lucky and it might explicitly state something like "2x512mb/DDR533 installed, 4mb/DDR800 maximum capacity" or if it's an HP or Dell you might be able to find your answer in the knowledge base section.

    if you're just looking to go from 2gb@533/667 to 2gb@800/1066, though, prepare to be underwhelmed for your money.

      Thanks for the tip. :)

      And I did google it but couldn't find anything of interest. Damn mobo, I'd buy a brand new if I had the money.

        What do you mean by "underwhelmed for your money"? PC2-5300 and PC2-6400 are pretty much the cheapest components in your computer. You can get 1GB for like $10 or less

          I think what he meant was it won't make much difference to performance.

            Re: RAM Question

            Basically I have two sticks of PC2-4300 RAM, and two sticks PC2-6400. Which means I can choose between having 2 GB fast RAM or 4 GB a bit slower, since the faster sticks get underclocked.

            If I pull out the slower ones the performance is pretty much the same in all my games, except for in FH2 where the game stutters a lot. When I put them in again it works smoothly without issues.
