MP3 Posted August 17, 2007 Share #1 Posted August 17, 2007 Advertisement (gone after registration) I've just upgraded my notebook PC memory from 1GB to 2GB. My Computer Properties do show 2GB of RAM, however, Window Task Manager > Performance do show the following: When Window just start up and only IE is running, Physical Memory (K) Total - 2095084 Avaliable 1519212 System Cache 469940 When I run Capture One and select a new collection folder for preview, Total: 2095084 Avaliable: 1472212 System Cache: 1555940 So it seems that XP is not really using the additional memory effectively, isn't it? The avaliable memory is more or less the same when running C1 or not. My user feeling is C1 does not make the preview thumbnail faster (when I click/select a new collection folder) after the additional 1GB SDRAM was added. Is there any PC guru here who can shed me some light on this topic so I can setup something so programs including C1 can effectively utilise the additional SDRAM? I know majority members may use Apple/Mac. Hope there are still some PC specialists here. :o Cheers. PS: I'm using C1 LE, WIN XP SP2, Sony VAIO SZ18 - 2GB RAM Link to post Share on other sites More sharing options...

Shootist Posted August 17, 2007 Share #2 Posted August 17, 2007 Don't use C1 much, if ever these days. I have it installed on a Core 2 Duo E6600, 2.4MHz overclocked to 3.4MHz, with 2GB RAM running XP Pro. That was the configuration of the PC when C1 was installed and has stayed the same. First thing I'd look for is a setting in C1 for available memory to use. Could be since it was installed on your PC when there was only 1GB of RAM that this setting needs to be tweaked for the 2GB you now have. XP will always page out to the HDD pagefile what it feels doesn't need to be in physical memory. Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted August 17, 2007 Share #3 Posted August 17, 2007 C1 is more processor hungry than Ram hungry and PS is more Ram hungry. Processor and fast hard drives are the key to C1 Link to post Share on other sites More sharing options...
MP3 Posted August 17, 2007 Author Share #4 Posted August 17, 2007 Thanks Ed and Guy I've looked through C1's menu, just didn't find any place where I can treak the avaliable physical memory. Do you think this is set automatically during installation time. That said, shall I try to reinstall my C1 LE again? ... Mine is Duo 2 Core - 2.0GHz Link to post Share on other sites More sharing options...
jaapv Posted August 17, 2007 Share #5 Posted August 17, 2007 Don't forget to (automatically) empty the preview cache ; it consumes tens of GB diskspace and slows up the program, using more RAM as well. Link to post Share on other sites More sharing options...
Bob Ross Posted August 17, 2007 Share #6 Posted August 17, 2007 Don't forget to (automatically) empty the preview cache ; it consumes tens of GB diskspace and slows up the program, using more RAM as well. You beat me to it, Jaap. Also look into the folders that C1 creates within the program itself for sessions, etc. Bob Link to post Share on other sites More sharing options...
AlanG Posted August 17, 2007 Share #7 Posted August 17, 2007 Advertisement (gone after registration) My user feeling is C1 does not make the preview thumbnail faster (when I click/select a new collection folder) after the additional 1GB SDRAM was added. I think you are onto a glitch that I saw. C1 will save the file adjustments in a collection when you change to a new collection. This may take a while if there are a lot of files in a collection and is disk related not RAM related. This "Save" feature supposedly can be turned off in the "Preference" setting, But every time I turn it off, it comes back on the next time I open C1.

pklein Posted August 17, 2007 Share #8 Posted August 17, 2007 Can someone tell me exactly what gets deleted when you empty the preview cache? Do the various adjustments you made to each image stay saved somewhere, or do they go away, too? I don't want to lose the adjustments, as that is the key to not keeping the 60 Meg TIFFs generated by C1. That means I can go back to C1 later and start where I left off, if I think of a better way to process a RAW file. --Peter Link to post Share on other sites More sharing options...

The only thing that gets deleted are the large preview images that are used on screen. If you delete the preview cache and later go back to a collection, the previews will be re-generated from the raw files using the saved adjustment information. I don't know if emptying the preview cache will speed up the program in any way. It just clears up disk space. Link to post Share on other sites More sharing options...

MP3 Posted August 17, 2007 Author Share #11 Posted August 17, 2007 Thanks jaapv and Alan, I shall take a look at the preview cache and the save option. The C1 interface is just ... glad that the its output image is not like its interface. Link to post Share on other sites More sharing options...
foolstop Posted August 17, 2007 Share #12 Posted August 17, 2007 I run my C1LE on a lowly P4, Northwood, 2G RAM. I think disk access speed is more important. I put the preview cache folder on one of my fast SCSI disk, I found it more efficient in displaying the working pictures. I also put up another folder for my "working photo", also on the SCSI drive, I found these two arrangements help in the overall performance of C1. By the way, if I don't remembered it wrongly, photoshop needs/puts aside at least 3x the size of RAM for the file that you have opened, you can read the size of RAM being depolyed in the bar at the bottom of the active window. I can still remember the days when I was using a 68L040 with 8M RAM with photoshop 2.5 Cheers. foolstop Link to post Share on other sites More sharing options...
MP3 Posted August 17, 2007 Author Share #13 Posted August 17, 2007 Thanks FY, so Guy is correct. Disk Hunger vs RAM Hunger. I just think, for a pro level raw converter, there better have some place where users could treak in the memory avaliable for the program or the program can automatically detect and utilize the avaliable physical memory.

foolstop Posted August 17, 2007 Share #14 Posted August 17, 2007 Well, for RAM assignment, Photoshop is more flexible on this area, no doubt, but not necessarily makes it the fastest among the various candidates. I have been using Bibblepro and DXO as well, both don't let the user to play around the RAM usage/assignment. Concerning the pic preview, (for DXO, I don't remember), for Bibblepro, I can also dedicate a SCSI disk for it, and even I don't, Bibble is the fastest to display the preview and the working pictures, among the three (four if including the C1). I think photoshop also store the preview in the disks, so make use of a fast scratch disk would also help. Cheers. foolstop Link to post Share on other sites More sharing options...

You can delete the collection in the thumbnails section. That will not delete the original RAW files. Link to post Share on other sites More sharing options...
