    Interesting - I had tried to search the drivers for my video card here http://www.geforce.com/drivers but there is nothing for download for the GT 130 on any Mac OS... looks like there is a different / up-to-date driver included in the CUDA SDK (maybe a driver from NVIDIA and not from Apple)

  • andreukmac Level 1 Level 1 (0 points)

    It did not work for me... if you check which drivers are included in the CUDA SDK, you will see that there is no driver for the GF 130 (only the GF 120). The smcFanControl workaround still works after a few days (no crashes): I turn the fans to "full on" when I am doing photo processing and I try to keep it under 50/55.

    I've been following along with the thread these past few weeks though I didn't bother with the fan control fix. I'm not entirely convinced heat is the problem as after a few rounds of Diablo 3 on the mac partition the heat did nothing to crash the system, whereas just running safari, itunes, mail and ical minutes after having just started up did. This is pure speculation on my part but in my amateurish research I've come to believe that the responsible party for this mess is nvidia and they are the only ones who can fix it, which is probably why we've heard nothing from Apple regarding the issue. I vaguely remember there being an nvidia upgrade via software update to OSX to the driver that corresponded with late Snow Leopard, the same time as these problems started appearing.

     

    Regardless of who's at fault I think it's shameful that hardware thats was perfectly fine is held hostage to the whims of a third party. My windows partition has never locked up once in my time using it, that'd be great if I only wanted to work in Windows but I don't. This is why I paid for my iMac, so that **** would just work. I found reports of people as far back as 2009 complaining of the same thing as their iMacs were having graphics card problems because of a software update. Is this just the new planned obselesence built in to iMacs wherein Apple and Nvidia scratch each other's backs and keep customers in an infinite loop of finger pointing? I wish we could get some answers.

    I used fan control as you did with moderate success for my GT 130. However, once I had the card replaced under Apple Care with a new, (revised) updated NVIDIA Ge Force GT 130 card I have had no freezes after 2 months of running graphic's heavy programs, videos uTube and anything else I throw at it.

  • andreukmac Level 1 Level 1 (0 points)

    can you be a little more specific: what do you mean by "revised updated NVIDIA Ge Force GT 130 card"?

  • Eclipsethegalaxy Level 1 Level 1 (5 points)

    I asked the service Tech what kind of a graphics card he replaced my NVIDIA GeForce GT 130 that was overheating with. He said he could only put in the same card. I asked him what if the same problem persists?

    Is it not same card? He said no, it's a newer, revised card. I was sceptical but after 2 months, I have been running flawlessly. So I can't specifically say what has been changed in the graphics card.

    Yes, I have exactly the same problem, with the same machine, same hardware, firmware and software:

     

    iMac 24" early 2009

     

    Chipset Model:     NVIDIA GeForce GT 130

    Type:     GPU

    Bus:     PCIe

    PCIe Lane Width:     x16

    VRAM (Total):     512 MB

    Vendor:     NVIDIA (0x10de)

    Device ID:     0x062e

    Revision ID:     0x00a1

    ROM Revision:     3370

     

    I hadn't seen the idea of starting in 32 bit mode before! I'll try it and see what happens. Since lion came out I've had the problem and tried many, many, possible fixes - including excluding Adobe flash, not running safari, turning up the fans..... and lots more.

  • CurleyMapper Level 1 Level 1 (0 points)

    Same problem here and it has been going on for about a year.  Went through Apple support and no one could figure it out.  My computer spend a day at the Apple Store and didnt act up at all and of course within 15 mins of plugging it in it froze.

     

    I just had an Mac expert in the area look at my computer and he got it to fail by running about 8 hd movies at once and from a cold start it took about 15 mins to get hot enough to fail.  The issue I face now is a $700 repair bill for a computer I paid over $2k for in 2009 that in my eyes is still a great computer just has a faulty part that Apple should be responsible for replacing. 

     

    This whole thing has soured my love for Apple products as its clear this is a hardware failure that has been exposed due to the demands of Lion.

  • Ramona Adams Level 1 Level 1 (15 points)

    The problem with my computer started with the Snow Leopard update just prior to Lion.  I actually bought Lion hoping it would correct the issue, but alas...now, I am waiting for Mountain Lion with the same hope.

  • Eclipsethegalaxy Level 1 Level 1 (5 points)

    Same computer, same year, same problem. NVIDIA GeForce GT 130. Had graphics card replaced under Apple Care. Running Lion flawlessly for 3 months.

  • Jesse David Hollington Level 1 Level 1 (35 points)

    Sadly, preliminary evidence suggests that Mountain Lion will do nothing to fix the problem either.  I held out the same hope, but it appears that it makes no difference (at least not yet).

  • Fustbariclation Level 1 Level 1 (0 points)

    I thought I'd fixed it... I rebooted in 32 bit mode and the machine has been up for three days without a kernel panic or freeze. Sadly it crashed again, in the middle of the night, when nobody was using it - NVIDIA again, of course, but it was unusual in that nobody was using it at the time.

     

    The watchdog time error looks like something a bit different - has anybody else seen this?

     

    I've now set it to always boot in 32 bit mode.. and I've not had flash running for a long time...

     

    Here's the crash - out of the blue:

    I've discovered an interesting phenomenon entirely by accident. Once when all the pixel artifacts started appearing on my screen I moved to restart my computer via the keyboard using control-eject but ended up hitting command-option-eject for some reason, I wasn't really paying attention to the keys I was hitting, and ended up force sleeping my computer. When I hit the space bar to bring it out of sleep, the artifacts were gone, and the computer continued to run without locking up on me. I don't know what this means, but I've used it on a couple of occasions and it's still working. Not the permanent solution I think we deserve, but could be helpful if it works.

    I've tried your suggestion but it just "delays" the final crash a little...

     

    By the way, I've found this other thread: https://discussions.apple.com/thread/3619873?start=0&tstart=0

    The latest messages from user joeldm propose something to fix it, I've not tried yet but perhaps it is worth a try.

  • Zahori Level 1 Level 1 (0 points)

    I've proceed as you Joeldm suggested in https://discussions.apple.com/thread/3619873?start=0&tstart=0, unchecking Enable Quartz Extreme, but I had a new crash after two weeks working fine.

    So I don't have any more ideas...I will have to take it to an Apple Store and most probably they will replace the graphic card installed (Nvidia GT120), as other users have commented here. But with apparently so much people having similar issues with this NVIDIA card (or GT130 one), I think Apple should investigate if this is a common defect on those cards and include them in a Replacement Program if that is the case. It wouldn't be the first time for a NVIDIA card, considering issues with GeForce 8600M GT in MacBook Pros...
