    Dan, my worries mimic your own. My Samsung branded RAM is what shipped with my MacBook Pro straight from Apple. It has the random freezing problem. I highly suspect the problem lies with the NVIDIA chipset too and that we'll never get a resolution to the problem because they have already moved onto newer revisions of the chipset which may have fixed the problem at the hardware level.

    Hi, just reporting back to say that I have not had any freezes in 4 days now. I am hoping that this resolves it for me. Will keep my fingers crossed. Does yours freeze up only once every week or two? That certainly would be better than what was happening before but still absolutely unacceptable. This is the last draw for me, Apple with need to do something about this after this.

    I noticed that my freezes most often happened when I moved the MacBook Pro (e.g. picked it up and put it down on a table). This pattern made me think that maybe the sudden motion sensor was causing some sort of problem -- e.g. it was parking the heads on the hard disk, but the computer was failing to reactivate the drive once the movement had stopped, which would account for why I can never find any log entries related to the hang.

    So I used this command line:

    sudo pmset -a sms 0

    to turn off the sudden motion sensor and haven't had a hang so far (couple of days now.) I'll post here again if the system does hang.

    Just posting an update - my system has not hung since I made this change, so I am very pleased!!! I'd be interested to hear from other people with the hanging Macbook Pro problem whether this fixed it for them too.

    Dan, were your freezes the type in which the computer completely locks up? The symptoms of this would include the cursor not being able to move, graphics completely locked up, any sound being played would repeat like a broken record. Or was it a freeze in which the spinning beachball cursor makes the computer largely unresponsive to input?

    Hey everyone...hope this helps the discussion. I have a unibody 13" from 2009...tried using macsales OWC ram as well as crucial (if I remember right) from newegg....both gave me freezes and caused the macbook to be unable to sleep unless there was a stick of original apple ram in the machine (hynix brand). I took a chance on voddy's advice and received the "original samsung" memory from OWC and so far I have not had freeze and the computer seems to be able to enter sleep when I close the lid. I'll cross my fingers, but I don't really know what "original samsung ram" means...I hoped/assumed that it meant that it came from other macbook unibodies. Anyways its been a little more than a day, which isn't long but the problems I spoke of occurred immediately after the upgrade with the previous ram I tried so I am hopeful. I will keep you up to date.

    I think I asked this on the old thread, but don't remember whether I received the answer. What manufacturer is:

    Manufacturer: 0x80CE

    I have 4Gb that came from Apple, and have the freezes you describe below. (No keyboard response, graphics frozen (not black or distorted, just frozen), sound -- if playing -- in a loop. When this happens, no log files are written, so there is no way to find out why this is occurring.

    Much more infrequently, I have gotten beachballs, and the dreaded "you need to reboot" message. Most often, just freezes.

    The freezes are no longer daily though, so either recent OS updates have reduced the problem, or I have adapted my usage habits so that they do not happen as often.

    Whoa! My brand new MBP is freezing hardcore at random times. Like everything locks up without warning and the only thing to do is to power off. I'm not computer savy like all of you! What do I do???
  • eremous Level 1 (0 points)
    Just an update guys...Its been about 4 days with the samsung original ram from OWC that voddy linked. I haven't had any sleep problems or spontaneous freezes that require a restart. As I said, previous types of RAM causes problems basically immediately after install. I'm hopeful that the problems stay away. Does anyone know what OWC means when they label it "Original Samsung Memory"?? Does this mean it is RAM from Macbooks (i.e. their rebate program for old memory) since the memory hadn't appeared on their site except in the past few weeks.
