    That is very cool! Time to go Ram hunting for my iMac too!

    p.s. Does MorphOS pick up all 4.5gb too?

    Did anybody test it in real?
    Are there any advantages over 10.5? Drivers for better GPU, boot from raid, etc... ?
    And what about new applications for 10.6 ? Aren't they distributed as intel-exe only and not universal binary?

    The iMac doesn't magically change the 31-bit addressing of MorphOS, which means 2 GiB RAM maximum. Minus address space for I/O etc. that's about 1.7 GiB usable RAM remaining. This is valid in general for current MorphOS, no matter the hardware platform.

    I recommend skimming over the linked thread. It's all discussed in there :-)

    Makes sense, didn't even think of that. Saves me some money then :)

    Thanks for the screenshots.
    Now everything is clear.
    My memory (not samsung) behaves the same as yours.
    I was surprised by the large use of virtual memory at 4GB. Apparently that's how OSX does.
