    Howdy folks, I ran into a problem when updating my Mac Pro 4,1 tonight that I'm hoping y'all can help with. The first mistake I made was trying to update two things at once, I should have known better (because it makes trouble shooting so much more complicated).

    I added an additional 8 GB of OWC RAM (adding 2x4GB sticks alongside the 6x2GB I already had). At the same time I added a Samsung 840 Pro 256 GB SSD into the lower optical bay slot. The drive itself seems to be OK, it is recognized and usable when dropped in a Voyager Q dock.

    To make a long story short, after going one stick at a time the RAM all appears to be fine, the computer sees all 20 GB now and seems to be running OK without the SSD plugged in so I don't think the RAM is the problem.

    Whenever the empty but formatted SSD is connected the computer starts acting really weirdly. It booted a few times but then the display would go blank after only a couple minutes. When this happened power remained on but I had to hold down the button to power off since I couldn't tell what was happening with the machine. It also restarted on it's own at least once.

    The most concerning thing however is that several times when the computer was started up the fans would start "revving." By that I mean they would go full speed, then slow/normal, then full, then slow: VROOM, calm, VROOM, calm, etc. This happened immediately after power on and I never even got a startup chime, eventually just holding down the button to power off.

    At first I thought I had damaged something during the upgrade process. I reseated all the RAM and the video card but it still persists. However unplug the SSD and the computer seems to be running like normal again.

    Is there a known issue with adding an SSD to the lower optical bay slot? Some sort of jumper or something that I needed to adjust?

    Thanks for taking the time to read all this, I appreciate any suggestions y'all might have. I did manage to get two different "system crash logs" when I rebooted and have included parts of them below.

    Hmmm, well I guess chalk this one up to gremlins or a ghost in the machine. It seems to be behaving itself with everything reassembled. I'm gonna wait a few days before migrating my system/applications over to the SSD just to make sure there aren't any other hiccups.

    Thanks for taking the time to read if you made it this far.

    I think that if you can shut down and boot up repeatedly with no problems, you're safe to proceed, but I understand erring on the side of caution. :p
