    I almost went back to SL.  Never had a KP until Mountain Lion.

    There was a 4870 and 285 and yes people used both of those.

     

    If you had any other model/number they were PC cards, such as GTX 260. (never heard of 265).

     

    It is possible but up until this last year or so there never were reports of issues with multiple Nvidia cards until someone put two together as the cause just by trying by removing one.

     

    I'd love to hear if MacVidCards can shed some more light what happens.

     

    I would love if there were 3 x 6-pin aux cables or something more than just the two, to allow 5770 + GTX 570.

     

    TWO QUADRO 4000 has / and has not / always worked - but that is rare and someone here and a couple people with that configuration over on Nvidia forum.

    cryptomagic & techmag, what's the status?  Things working?  I'm about ready to order my card.

    Hey Tim - rock solid - ZERO crashes since the hardware upgrade.

     

    I do have a memory issue with the kernel eating up 11GB of RAM and yes I've read all about how it's *supposed* to do that but when it literally takes minutes to open a web page (or change tabs, or flip between already running apps) I'm pretty sure something is actually worng

     

    The ONLY reason I mention that is that was the trigger for me to do the Mountain Lion upgrades in the first place. (Frypan => Fire...)

     

    For a balanced account however Moutain Lion is way better than Snow Leaopard on the memory issue - at least in my experieince now that I've actualy seen what a running machine is like beyond a single day.

     

    I've dicovered the wonders of 'purge' and that helps - thanks to purge and restarting Safari dialy I can now go about 3 (almost 4) days between boots and still have a reasonably functional machine. I have JUnit test suites that take days to run so yes not rebooting daily IS important to ME.

     

    Back to the matter and question at hand:

     

    I have tortured this machine specifcially to see if I could get it to crash and nothing (yet). My theory on testing is "you don't test for thin ice with a feather duster - you test for thin ice with hobnail boots!")

     

    So 50+ social media windows (heavy flash, ajax, video, html5(ish) stuff going on for DAYS) and no crashes.

     

    So far so good.

     

    And yes I know this doesn't "prove" anything but it is goes bang like a smoking gun and it smells like a smoking gun...

    What are you talking about 'purge'?

     

    I agree with your testing strategy.

     

    Guess I'll order my video card.  I hate to spend $250 to fix this but I've had enuf of it and it's a whole lot cheaper than a new computer.

    Apologies, I have a GTX275, its been in a while, it was "tweaked" some time ago, but then again it didnt cost an awful lot either.

     

    That with my GT120 results in maybe 1-2 crashes a week, dependant on what I do and when. so I am not seeing daily crashes.

     

    I'm going to tough mine out for a bit as I'm happy to reboot if needs be to give me a little longer till a crash.  Its annoying but I can live with it for a bit.

     

    I'd just go out and get a replacement card but I'm an old stroppy git and dont feel that I should be looking for work arounds for this. I, like many others made a significant investment in this machine and was looking to get a bit more than  4 years out of it, maybe thats just me being old and opionionated. I dont work it hard, in fact I suspect its underworked. 

     

    For those that say just protect your investment and just get the card its cheap, yeah, in guess in the grand scheme of things it is but for me its the principle. 

     

    I'll keep following this to see if Apple fix it.

    Open up a terminal session and type purge, this frees up disk and memory caches.

     

    Load up activity monitor and look at the system memory before you do it, its effectivly returns the cache to a state similar to the state after a reboot.

    Please keep us in the loop on this - I'm especially excited if the ATI and the GeForce play OK together.

     

    How does performance seem to hold up?  Any noticeable difference?

     

    Performance has been great.  But I'm a developer not a gamer or graphic designer.  However, I run lots of Windows VMs (for testing) and I frequently switch between Unity and Single Window modes.  On the ATI, it is smooth and instantaneous.  On the GT 120 it staggers to do it, taking several seconds.

     

    The ATI 5770 (for 2 displays) and GT 120 (for 3rd display) play together for the most part.  It's been 4 days and no KPs.  Once in a while the monitor on the GT 120 will forget it's Background or Arrangement position so I'm going to order a MiniDV (female) to DVI (male) adaptor and try running my 3rd monitor on the 5770's DVI port.  I think Hatter said that would work.

     

    One other thing improved.  I like to have "Wake up on LAN" in my Network Preferences so I can SSH to my MacPro after it falls asleep.  When I went to Lion, the GT 120s went haywire and my monitors would flash on and off all night so I turned that off.  With the 5770 and one GT 120, it works great again.

    If using more than ONE such adapter, all adapters must be ACTIVE (contain signal re-drivers) or the third display will not light up with the second in place (each will light up by itself).

    If you are getting Kernel Panics when booting up...try doing a Safe Boot by holding down the Shift key until you see a status bar on the bottom of your screen.  If it gets past the Kernel Panic then you know it is an issue with a Driver you have installed for something you have running on your tower. 

     

    I just updated to 10.8.2 from 10.6.8 and I started getting kernel panics...I thought it might have been a driver for my GT120 card I had installed.  So I did a Safe Boot and installed the latest drivers for my card, and it kept giving me kernel panics. 

     

    After doing a little research I found out it was a driver for my Sonnet E3 SxS card reader.  If any of you use the Sonnet QIO card readers, you will have the same problem. 

    Follow this link and it will walk you through the steps to do a Recovery Boot to remove the driver. 

    It took me a minute to figure out how to correctly type out the sequence in Terminal, but it worked for me and I no longer have Kernel Panics!

    Early 2008 Mac Pro (MacPro3,1) OS X 10.8.3 (12D78), NVIDIA GeForce 8800GT driving 2 x BenQ 1920x1080 monitors, NVIDIA GeForce GT 120 driving a Samsung 1680x1050 monitor, 12Gb RAM, and so on...

     

    Machine was rock solid for years, not a single crash and now this - after upgrading to 10.8.2 started getting multiple KPs a day but the 10.8.2 supplemental update seemed to fix it. Then on to 10.8.3 and the KPs are back (sometimes as many as 3 a day) and no sign of a fix.

     

    Need to run 3 monitors as I do customer support and need 2 monitors dedicated to that while I use the 3rd for my OS X desktop. Really don't want to splash out on 5770 cards in the hope that it'll stop the KPs, would sooner invest the money in something new. Such a shame though because I was patting myself on the back over how Apple were still supporting a 2008 vintage Mac in Mountain Lion whereas the reality seems to be that they've got more important things to do now, and what is a perfectly serviceable machine gets relegated for want of what is probably a simple software fix.

    Two NVIDIA graphics cards have been a problem in 10.8 when both were GT120s. Perhpas you are stepping on the same land mine.

     

    I think the Apple-firmware 5770 for about US$250 may be inevitable.

    May have found a solution to dual GeForce 120 cards causing ML kenel panics in early 2009 pros. Nvidia has new driver bundle for mac 120s on their site. Just installed and fewer beachballs. Fingers crossed! New drivers dated 3/15/13

  • cryptomagic Level 1 Level 1 (0 points)

    I have not been able to find such an adaptor.  Maybe they don't exist.  To be crystal clear, I'm hoping to connect my 3rd 24" LED to the DVI port on the 5770 so I can remove the remaining GeForce 120.
