    I just got in my mac pro and ordered some memory(2x512) from crucial that has some standard size heat sinks covering the board and put them in with the OEM Apple memory (2x512's) and it seems to be running fine.

    I have no noise or acoustic differences, and dont notice any instability all. I have run MemtestOSX and opened all programs at once and have looped memtest for 24hours with no hiccups...

    With that being said, does anyone have any recommendations for how i could totally slam the system resources for an elongated period causing the computer to work its hardest and possibly cause instability? I would like to find out if this memory is TRULY going to be stable NOW instead of getting deep into a project and having it crash... If this all checks out then why not just buy 4 for more of the standard Fully Buffered Dimms instead of shelling out cash for these unneccasary Apple Certified modules...?

    If anyone has any ideas let me know...

    Thanks,
    Scott

    I'd suggest running as many heavy-duty apps doing hardcore tasks such as rendering HD at once and then hide them and do normal stuff on top of it and see if those normal apps are more prone to crashing, ie, Safari, Finder, etc.

    i got the memory before they 'yanked' everything off of their site. I know that i probably SHOULD return the Ram and purchased some approved memory but this stuff is working fine and it was way cheaper than the stuff from Apple or the Approved stuff from OWC.

    I heard of people having Soft ECC errors on forums but i haven't recieved any issues at all.

    I know could render up HD material and do manual processes to stress the machine, but i would like to run some kind of loop and let it run for 24,48,72 hours and see if it crashes....

    I figure, worst case, it blows up, i return it to apple.

    If bad RAM fries something on your computer -- it is NOT covered by AppleCare. As in, if it goes bad, Apple isn't going to help or cover the cost of repair.

    MemtestOSX bascially runs the same patterns as Memtest86 and i have run it for 12hrs straight and it made it through 38 loops with no problems...

    I have the cover off of the Mac to see if it gets any hotter and the temperaure of the modules (using an infrared Thermometer) is only a few degrees different between the OEM memory and the NON-OEM.

    Yea, but apple does not say that you cannot use 3rd party ram, their only warning is that if you get the same spec memory (which they provide the specs) but don't get one with the huge heatsink, then the system "may" run lounder, or the ram "may" run slower. Nothing about their being an issue with 3rd party ram killing your system :)

    I think alot of us are still thinking of the good old days with Apple designed motherboards. Now with the use of an Intel board, I think the use of properly speced memory will be fine.

    I've been using the crucial memory for several days with no problem at all. YMMV...
