Sequence Goes Orange after adding 4GB of RAM

[Chris Borjis]

if nothing else but the memory has changed, something is wrong
with that memory or the riser configuration (where each stick is installed)
is the problem. Or the existing memory you have doesn’t care to mix.

try removing all but the new memory and see what happens. if it works
fine, then google the memory riser configurations to see if you can make it work.

I upgraded to 4GB some months ago. I got it from 4allmemory dot com.

worked great and a fraction of the cost apple would have charged.

I had similar problems, until I read this on the Apple site:

Once I had my RAM installed in the correct configuration, all was well…

Is your ram all from the same manufacture? I have the original Apple Ram that came with the machine and Kingston. Everything seems to be running fine without dropped frames but still cannot get rid of the orange.

I am currently using memory all made by the same manufacturer. The backstory is:

My MacPro originally came with 2GB RAM preinstalled, and then I added 4GB from crucial.com, to make a total of 6 GB. But my performance was lousy – I had to render stuff I didn’t even have to render on my iMac, which had way less RAM.

I tried removing the crucial.com RAM, so that it had only the original Apple 2GB RAM, and it got better, but not great. Then tried just installing only the 4GB from crucial. Same thing.

After reading this document:

https://support.apple.com/kb/TS1957?viewlocale=en_US

I realized that its critical that I had the right configuration of RAM. The Mac Pros have 2 “risers” inside, and Apple is recommending that each riser has either 2 or 4 DIMMs, for a total of 4 or 8 DIMMS, all of equal size.

I bought another 4GB (2x2GB) from crucial, installed them along with the other 4GB (2x2GB) from crucial, so that I had a total of four 2GB DIMMS installed, two on each riser, for a total of 8GB, and suddenly it’s like my hands were untied, and my performance improved immensely.

Hope that answers your question. I don’t know how critical it is to be using the same manufacturer for all RAM, though I think that is the prevailing wisdom. I gave the original Apple 2GB RAM that came with my computer to someone else in the office. He’s using a mixed bag of RAM in his computer, and it seems fine, though he doesn’t use FCP.
