how can i get photoshop to use all the ram installed
Are you running the 64-bit executable?
If you are using the 32-bit version of Photoshop CS6 the maximum amount of RAM available is 3.25GB. If you are using the 64-bit version you can change the amount of RAM allocated by: 1) click on Edit 2) click on Preferences 3) click on Performance 4) click the + on the slider to increase the amount of RAM available to Photoshop. 5) click on OK
