Win7 64 bit
16GB ram (was 8GB before today)
60GB SSD for programs and scratch use
external usb hd for storage (I keep all photo files on there and don't move them to the ssd when working on them)
So as I have started to use more advanced post processing workflows in photoshop which can lead me to a document with MANY layers, I kept running into out of memory errors when trying to save or crop, probably some other things too. My computer even just went black a few times forcing me to force power down. I have plenty of space (30 gig) available on the SSD and I thught ps would just use that when it ran out of memory. Since my task manager was routinely showing me using 7+ gigs of ram when running ps, I decided to buy 8 more gigs today.
I installed the 8 gigs, and was able to work on the large panorama I had been trying to work with, and was causing the computer to black out. Was able to do the crop that was crashing my system. Also found that with the document open, I was up to 14 gigs of ram being used in no time. I decided to save and reboot ps to try to clear some of the memory usage as I had done before the upgrade to get through memory bottle necks and optimize the document to reduce memory load. And I got a damn out of memory error. Luckily quitting chrome and bridge freed up enough memory to allow me to save. What I really don't get though, is why doesn't it just use the scratch disc and get on with it?
Now I'm wondering if I didn't just waste my money and should have instead just gone for 32GB of ram, but that would have been like 2.5x more money. Although, put that way, it would have been a 4x increase in ram. Alas, I don't plan on upgrading the ram again any time soon. Would getting a standalone gpu card help me out here? Would ps be using the ram on the video card?
