Installing Quadro4000 and added RAM into a mac pro
I have a Mac Pro 2 x 2.26 GHz Quad-Core Intel Xeon with 12 GB (2 x 6) 1066 MHz DDR3 ECC RAM which I am trying to upgrade. I installed 2 4 GB 240P DIMM DDR3 PC3-8500 RAM cards and a VCQ4000MAC-PB Quadro 4000 2GB GDDR5 Card into my Mac Pro following the directions I found in an online manual for my model of Mac Pro (early 2009). I have two monitors. I plugged one of the monitors into the Quadro 4000 card and left the other one plugged into my ATI Radeon 4870.
When I turned on my computer, the system informed me that there was a problem and recommended I push any key and allow the system to try to load again. No luck. I then plugged the monitor currently plugged into the Quadro 4000 card back into the ATI card thinking that might be problem. No luck. Now I am wondering if maybe the RAM might be the problem (conflict between the 2 GB RAM cards already in the system and the new 4 GB ones.
I’m over my head and need help. Anyone out there have some guidance for a not too techie kind of guys?
Thanks so much.

The key to troubleshooting is eliminating variables.
Remove the Quadro 4000, but leave the RAM. Try to boot with the ATI in its original configuration and the new RAM in place. If that fails, remove the RAM and boot. If that works, the RAM is the problem.
If you can confirm the RAM is good, try adding the Quadro back in (though I don’t recommend running the Radeon and Quadro together — better to power both monitors off the Quadro).

Thank you so much for your suggestions. I will do then immediately. I have one dumb question though. I thought the Quadro 4000 could only power one monitor. Based on your reply, I must be mistaken. I will let you know how your suggestions work out and thanks so much again.

My RAM is working perfectly now but the Quadro 4000 card (I think) is causing an error message – the chord connecting the card to the board is not connected properly. I have checked several times and the connection seems secure to me. Is there some suggestion/trick that can get me beyond this point? Thanks for your help.

The Quadro 4000 should have both DVI and DisplayPort available.

Are you referring to the power cable? Have you un-installed the ATI card at this point?

I had not removed the ATI card when I posted this. I have now removed the ATI card and the Quadro 4000 is working as advertised. Now, on to resolving other issues and — hopefully getting some editing work done.
Thanks all for your help.
