Pairs in some models, singles in others. Cheap in some models, really expensive in others. Eight core is impressive in some models, a big yawn in others.
What model do you have?Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers
Your 8-core features Multi-Threading, and under certain circumstances performs as if it had 16 cores.
Your memories are cheap and can be upgraded by single DIMMs. Slots 1,2, and 3 are independent, slot 4 is shared with slot 3.
8GB DIMMs for that Mac Pro tower, from several reputable, Mac-centric vendors can be had for under US$80. You could install three on each side for under US$500, two on each side for under US$320, and still have room to grow.
There is a slight risk that 8GB DIMMs and 1 GB DIMMs will not play nice together.
Use this rhyme to select an appropriate Vendor:

Thanks for the links. Those are the ones I've been haunting. Haven't been reading the fine print yet but will before I buy. After springing the dough for the MP I'm thinking two times eight and grow from there... Maybe they'll come down farther in price. Yeah, right! Re: the one gig sticks. Didn't think they would play well together but had to ask...
The eight cores perform like sixteen? Tell me more. Don't know of your uses for the MP but my prime reason was video/audio. And as stated, I didn't really think the sixty second After Effects project would take that long to render. If you have the time, could you enlighten this old codger on the finer points of processors and memory, or point me in the right direction?
Thanks again, Grant.
PS, Hope you're far enough 'West' of Boston so as not to get buried in tons of snow. I perferred a more tropical climate which is why I now live on a rock in the middle of the Caribbean. :} Hurricanes? We don't get no stinkin hurricanes! Sandy didn't even blink an eye when she went by...
Use this article to examine memory usage while ypu are doing your video processing. I expect you will find "free" memory (green on the pie chart) goes immedaitely to none and stays there until you are done.
But what is much more telling is looking at the PageOuts Up-counter. PageOuts occur when there is Nothing else that can be declared surplus, so modified pages have to be copied out to disk, then copied back in later. It keeps on working, but takes forever because you are simulating the memory you don't have by using a disk file.Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers
Grant, sorry I didn't get back sooner but there wasn't any notice on my email and I got busy.
I was using the activity monitor while rendering and, with the six gigs, never saw more than three or four being used at any one time. It would bounce back and forth during the 'heavy parts' but averaged around three, three and a half.
About those certain conditions on the processors you mentioned. Shouldn't they help/kick in on the processing part of the rendering process? I'm pretty fuzzy on that stuff, even after using Macs all these years. Call it, selective information gathering...
At any rate, I'm planning on adding, maybe four of the eight gig sticks soon and want to confirm their placement. I should remove all the one gig sticks and put two in the first tier and two in the second, right???
Again, thanks for all your advice.

Most rendering Applications will 'spread out" a bit if there is more memory in the machine, but if you are staying under 4GB used (with 2GB free) you do not seem to be memory limited.
Next, take a look at Processor Utilization. This article, aimed at portable computers, hits all the high points about Processor Utilization:
Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity
The next issue to examine is Disk Utilization (more than just fullness).Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers
