    How much RAM does Puma support up to?

    Is it 4Gb of DDR2 800? That's what my searches came up with.

    In other words, it's still lagging behind Intel by 1 generation?

    I believe it is the motherboard that decides the amount of ram while the OS decides how much is actually usable. ;) dont quote me on that.

    Also my belief.
    AFAIK, Ultimate-64 supports up to 128gig RAM, but no hardware does yet

    Also should add Chipset is what decides the speed of the ram.

    The difference between 667MHz and 1066MHz is greater than 800MHz to 1066MHz. :)
    800MHz will be fine. :)
    But how much RAM it supports I'd like to know too. :)

    Well, if a proc is 64 bit, it should be able to support 16 exabytes of RAM (that's 16X1024X1024X1024GB) provided each memory address corresponds to one byte. The limiting factors are the number of physical address lines on the motherboard and the limitations built in to the OS.

    processors can usually make use of a lot of memory. I know AMD released tech specs of the opteron series processor which I use in my laptop and it said that the cpu can make use of up to some 128 Tb of memory.
    No laptop can make use of anywhere near that much memory, but servers can make use of at most 128GB. You can get a $2000 tyan motherbaord and outfit it with 128Gb of memory but that is ludicrous and unnecessary.

    AMD processors have integrated memory controllers, so even if you had Pc4200 memory in your system, it will outperform an intel platform with PC5300/pc6400 memory.
    Heck I have 2gb of Pc3200 in my laptop and it has a higher memory bandwidth than the 2gb of PC8500 dominator memory in my brothers intel desktop.

    The memory is usually never the bottleneck (MHZ wise) so dont worry about it. If you had two systems side by side, one with 533Mhz memory and the other with 1066Mhz memory, you wouldnt notice any difference if both laptops had the same specs other than the memory. The performance difference will only show in synthetic benchmarks

    I amend my previous statement. If the memory controller is integrated in the CPU, then in a manner of speaking, the CPU does limit the available RAM based upon the limitations of the memory controller.
