RPi with 512mb Memory?

wallarug
wallarug over 13 years ago

I just found this: http://au.element14.com/raspberry-pi/raspbrry-modb-512m/sbc-raspberry-pi-model-b-512mb/dp/2191863

 

Is this a raspberry pi with 512Mb RAM or is this a joke.

    Great find! 

     

    A 512MB model is consistent with the 31 July announcement

    that Android 4.0 is being ported.  It seems all the recently

    announced ARM devices have at least 512MB, and Eben's

    recent interest in benchmarking against these devices indicates

    he is paying attention to what the competition is doing.

     

    There seems to be a recent pattern where RPF is paying attention

    to issues that previously they said were inconsistent with their

    educational mission, such as MPEG-2 decode, polyfuses,

    and now 512MB ram.

    we don't know anything for sure, but apparently the ram can be upgraded

    to 512MB simply by replacing the 256MB PoP ram chip with a 512MB chip.

    So no board redesign is needed.

     

    There have been some hints of board redesign, such as to align the USB

    connectors, to move the capacitor that tends to fall off, to achieve

    residential FCC/CE compliance, and to fix the 1.8v power issue.

    But any such redesign would presumably work with either 256MB or

    512MB memory.

     

    I don't know whether 512MB is the maximum that the SoC can support,

    or how difficult it might be to modify the SoC to support more ram.

    A lot of the competing ARM devices appear not to use PoP ram.

    Instead, they use DDR3 ram, typically two 256MB chips, for a total

    of 512MB.

    The RasPi forum has just twigged to the 512MB version: see this thread.  On 31 August jamesh said that 512MB is the limit for the current board.  He didn't give away any RasPi Foundation plans.

     

    It may be that the Ohmless F1+F2 and 512MB are the only changes.  I expect these can be done without recertifying.  Any significant board change like moving connectors generally requires recertification, which is painful and expensive.  It's also a pain to deal with multiple board versions, so if most people are able to survive "as is" there's a lot of incentive to wait on major changes.

    Just read the above.

     

    Doesn't say much about the new model.  Maybe this is meant to be a sceret. image

     

    Keep updates coming though here.
