sanyasi Posted September 9, 2014 Share #21 Posted September 9, 2014 Advertisement (gone after registration) For others who will read this thread, I have 16 on my Macpro. It does what I need to do fast. Make sure you save at least 20% of your hard drive for scratch space. Link to post Share on other sites More sharing options...

algrove Posted September 9, 2014 Share #22 Posted September 9, 2014 It is but that is a very expensive S after the R..... Just imagine what the Z will cost! Link to post Share on other sites More sharing options...
Bill W Posted September 9, 2014 Author Share #23 Posted September 9, 2014 Just imagine what the Z will cost! There is an S for sale on Craigslist locally. $9000. No lens though.... Link to post Share on other sites More sharing options...
algrove Posted September 9, 2014 Share #24 Posted September 9, 2014 There is an S for sale on Craigslist locally. $9000. No lens though.... Then add another $9-11k for a very good lens! Yikes. That 645Z sounds like a better prospect. Link to post Share on other sites More sharing options...

algrove Posted September 11, 2014 Share #26 Posted September 11, 2014 A friend mentioned that on the Mac Pro model 5.1, even though there are 4 RAM slots, using more than 3 in fact slows down the Pro since it was optimized for using just 3 RAM slots. Anyone know about this and have comment? Link to post Share on other sites More sharing options...

Anyone know about this and have comment? I have never heard or read that. It would seem bizarre to design a computer that way. Link to post Share on other sites More sharing options...

Anyone know about this and have comment? Your friend might be talking about how the machines RAM latency can increase with the wrong RAM regardless of how much you install, thereby diminishing total memory throughput to a max of 8gb/s. To get the max 16gb/s use two Fully Buffered DIMM (FB-DIMM), one on each bus (card). Link to post Share on other sites More sharing options...
sblitz Posted September 11, 2014 Share #29 Posted September 11, 2014 Leave lots of space on the hard drive, will make a difference. I have a macbook pro 2009 vintage and recently removed all photos and put them on a separate portable hard drive (which I back up onto twin hard drives). Since doing that, my machine flies! Anyway, something to keep in mind. Link to post Share on other sites More sharing options...

Anyway, something to keep in mind. Absolutely true. Having to write to RAM and retrieve is what slows the machine down. Link to post Share on other sites More sharing options...
pico Posted September 11, 2014 Share #31 Posted September 11, 2014 .... And if you use Photoshop assign your scratch discs to other than the boot disc. Spread the scratches over physically separate devices if you have them. Adobe uses its own page/swap file management. When I did this stuff for a living I did what I mentioned then added enough RAM that PS never touched disc until I saved. Do that and be happy.
