    mine hover around 49 C (120 F) and under load can get up to 55 C (just over 130 F) with an ambient temperature of 25 C.

    temperature depends how much RAM you have installed. and yes, 63°C is normal and well under limits. OWC had a good post about the specifics if you really want to know.

    One of the two sticks I got from Apple runs at that temperature.
    I can tell you I'm not very happy about it. At the prices Apple
    charge, they should be checking thoroughly for consistency.

    Ram temp will also depend on what slot it's in. Keep in mind your CPUs run at different temps based on load, hence the ambient temp of the air cooling the ram (and thus the ram temp itself) will vary. Also consider what parts of the system's memory are in use (Hence which sticks are being used) and other factors. Getting all four sticks at the same temperature is possible..... when the machine is off;)

    While that's true, it's also true that some RAM runs hotter.
    You tell by switching it from slot to slot.

    You're missing the point. Take two supposedly identical
    sticks of RAM A & B. Measure their temperatures, swap
    their positions and measure again. If A's new temperature
    is hotter than B's old temperature, it's a reasonable
    assumption A runs hotter than B.

    b1&a1 run hotter @ 60 or plus, i think theyre stock.

    mac pro 2x2,8. 4gb, 2gb stock. 4x1 :)

    At this moment, with an ambient temp of 26 degrees C and nothing other than Safari and iTunes running (i.e. ~ 90% idle), my top two RAM modules are running at 60 and 65 degrees C, resp.

    It's absolutely nothing to make a fuss over.

    Well it's good to hear that. But the scientist in me wonders why
    the discrepancy between my RAM modules? (One is consistently
    hotter no matter which slot it ends up in).

    The only explanations I can think of:

    (1) Dodgy sensor.
    (2) Poorly applied heatsink.

    my top ones (a1, b1) are 58 and 60
    a2 b2 are 52 and 54
    ambient 24

    idle 100% in iStat, 99% in activity monitor

    The RAM in my PC (yes, I know that this is a Mac forum) gets to the point where it actually hurts to touch it, but I'm not sure of the actual temperature.

    Odd. It's the other way around for me: the a1/2 modules
    are the cooler ones.

    You don't stand your Mac Pro upside-down, do you? :)

    No, you're missing the point. I wasn't arguing with you, I was appending your statement. I'm not saying some sticks don't run hotter than others, I'm saying there are also other factors that can contribute to ram temp differences beyond stick variance.

    It had already been appended. I did it when I replied to you.

    Nitpicking: prepended in your case.
