MatLab needs more RAM? OpenGL?

    Hello,

    I recently bought a Macbook Pro, 2.4G, 200GB HDD, 256MB graphic card, 2GB RAM.

    I used it mainly to do Image Processing programs with MatLab, which are pretty heavy.

    Sometimes MatLab says it has run out of memory and my only option is to quit the program and restart it again. (Clear all doesn't work!) I don't know if that means it uses all the RAM, but the other day I was using Time Machine+MatLab+surfing and on iStat Pro it said I only had 100MB of free RAM and the programs were going really slow.

    Should I update to 4gb? I've seen memory in Newegg for 78$ (Kingston) that everybody says works very nice.

    Apart from that, what's that thing abut OpenGL with MatLab?? Is it related to the memory you use (Ram or graphics card??)

    Thank you!

    So Kingston is a nice brand? The price seems very good to me.

    Yes MatLab is very intensive of memory usage. All that number crunching is cpu & ram intensive. MAX it Out.

    Kingston Value RAM NO!!

    Right now I've seen people having trouble with the Kingston VALUE RAM (which is the one I was looking for) because their computers crashed more often.
    The Kingston specific RAM for Macbook Pro is $101 which is the same as OWC or Crucial!!

    So between these 3, which one should I use?

    They'll all be perfectly OK. So pick whichever is the cheapest or offers the best service... Crucial's is usually pretty good.

    I just got 4GB from OWC for $96 shipped. BTW i ordered the RAM on the same day that i ordered my Refurb iMac and the RAm was delivered yesterday the iMac will not be here until next week.

    Many people post their problems with Value RAM in different forums! I think that for $20 less its not worth the possibility of crashing! Specially when you spent $2000 on the machine...
