    I am interested in buying the 2.8Ghz Mac Pro and then OC'ing it to 3.2Ghz.

    The ZDNet article says that the quality of your memory is the bottleneck when overclocking. I don't want to buy some cheap-o memory that will flake out when pushed beyond normal capacity.

    I was going to buy from either OWC or TransInternational, but I don't know who makes their memory or if their memory is good for overclocking.

    Any ideas?

    Nowhere.
    It will void the warranty on the RAM and on the Mac.
    FB-DIMMs are not made for overclocking and there will be heat issues.

    Wow don't be so sensitive guys.

    Overclocking isn't really a big deal, especially if the voltage stays the same. It's sort of like just putting your computer in a different gear.

    I guess it's sort of a foreign entity to Mac users but if you talk to any knowledgeable PC enthusiast with a PC with a Intel Core CPU, overclocking is pretty much the norm. In fact I know many people who have overlocked their 2.4ghz processors to 3.4ghz.

    Kingston or Transcend work best.

    I took out the 2 OWC ram pieces and just used the original apple ram and overclocked my 2.66 Mac Pro to 3.1 ghz, pushed it to 3.2 but it panicked.

    Use SMC fan control, turn the fans up around 1000-1200 RPM (CPU fans) and you'll be just fine.

    Core 2s are ridiculously forgiving. Memory is not. FB-DIMMs are probably worse.

    I guess the Mac overclocking tool is pretty tame (2.8 to 3.2, .4Ghz), but giving the memory a little kick couldn't hurt.

    My original plus 2 Kingston Dimms accepted 3.2 GHz whitout a problem. I could even go to the maximum possible frequency whitout getting any memory errors, but I didnt test the clocks over a long period. As long as the mac pro is fast enough I won't do any overclock. (except the graphics card... :))

    Thanks so much for the very helpful replies so far.

    Any reason why Transcend is so significantly cheaper than Kingston? Is it worse quality or something? Also can I just buy some ram sinks instead of that fan unit? I dont want to increase the noise of the system.

    Two things on the first bit:
    1. If CanadaRAM, who has a website that sells RAM, says it's a big deal, it's a big deal.
    2. Again, FB-DIMMs aren't normal RAM. It's on your head.

    Second bit:
    In a server? Because that's what the Mac Pro is. Server chips and server RAM.

    Hey this CanadaRAM site seems like a good place to buy the kingston modules. Thanks! :D

    What does that have to do with the ECC ram needed for the MP?
