A little disspointed with 8GB RAM although I am using it: Only 2GM Memory free

You can never go wrong with more RAM
.
A quick question then, are more "ram chips" on the actual memory module better or worse? The kingston 8GB i bought has 8 small black chips rather tha the 4 big ram chips I wanted. Is it better to have 4 big ones or 8 small ones?
If you're opening a 10GB file while having only 8GB of RAM, especially with other files or apps open, your system will be doing some heavy duty swapping to disk. A faster drive will help, but more RAM would help more. It could also be that some process being called by Preview to render the PDF may not be 64-bit, and therefore unable to take advantage of all available RAM.
Thanks for the tip! Although I love iStat and long ago came to rely on it, I didn't realize that it would provide Page Ins and Page Outs directly from the iStat window. Heretofore, I have always clicked the Activity Monitor icon in the iStat graphic to get them. Thanks again!To change the memory in iStat to advanced, just click the small "i" in the widget, select "Sections", and change memory to "Advanced"
I have no idea. I typically go with the specs of the memory rather on what it looks like.
If there is an effect, it's completely negligible.
You could try splitting one of the huge files and see if that makes it run better.
In any case, judging by the pics somebody REALLY needs to learn to use a scanner.
You don't need TRIM with the new SandForce controller SSDs -- they have built-in garbage collection to prevent drive degradation. It seems like Preview cannot access the drive fast enough with such a large file to suit your needs. You absolutely need an SSD.

This should suit you well if you only have 80GB of data to analyze. If you have more data you can buy an external and transfer back and forth but that might get tiring after a while.

OP you need a Mac Pro with fast SSDs in RAID 5 or something. 10gb PDFs on a laptop? .............
That 5400rpm drive reads probably at 80mb/s max while a good SSD (SandForce or Micron) does 250mb/s+.
A 2010 Mac Pro with 3 SSDs in RAID 0 can probably do 700-800mb/s, letting you open a 10gb PDF in about 15 seconds.
Plus you'll probably need like 32gbs of memory...
If you're doing this type of work (scanning/archiving old ass books), why don't you have a better machine aka get the 12 core Mac Pro + 30" Cinema Display?

with 10gb files you are asking too much from your internal HDD.
An SSD will probably be fast enough but if your files are so massive you will be limited by the storage it offers.
I think that kind of work should be done on a desktop.

Yup, especially if you're doing work with such large files for hours.
You need more ram.
Well I can open the pdf file in about 15-20 seconds already. Its just organizing, manipulating etc that it gets really slow.
I think a SSD would be good, but like other said, I need mroe ram. What Im going to do Is split the pdf file into 5-10 parts and go from there. Sure it creates more time but my workflow would be much easier to handle with smaller pdf files.
Our UC got some of our grants cut, so getting access to Mac Pro ith SSD and 32GB probably wont happen. Ill see if I can get a SSD out of them.
Just a Thought
Are You booted into the 64bit kernel might not make big difference but it's worth trying I've made my mbp always boot into the 64bit kernel to try it out simply hold 6 and 4 at startup
