I have tried a solution recommended on this forum:
''Go to start and type Regedit---- and open----click on (HKEY_CURRENT_USER)----(Software)---(Adobe)--(Photoshop)---click on the Version ex:80.00----- in your Right side Right click and create (New-- DWORD (32-bit Value)) and rename it as (OverridePhysicalMemoryMB) and open it and change to Decimal and value data to 16000 and click ok''
BUT...after I change to decimel and value data to 1600 and click ok...when I reopen the file (OverridePhysicalMemoryMB), it automatically reverts to hexadecimel.
Well, RAM isn't something you can HACK! Your registry knows how much usable RAM is has. I wold be curious to see what article you are following. Post back here, or in case you prefer; REVERT with details!
