i have 4gb memory and i need to decrease it to 3gb using bcdedit /set removememory 1024
I tried that but Vista 64 didnt boot anymore...I tried command again when my computer had only 3gb memory installed, command worked, only 2gb was available when vista started.

So why that command doesnt work with 4gb installed?

    You should also be entering the GUID that is associated with your boot entry with the command. For example...
    bcdedit /set {18b123cd-2bf6-11db-bfae-00e018e2b8db} removememory 1024

    The area in the {} is the GUID for your system's boot entry. See this link for information about a GUID. Use the bcdedit /enum command to locate your GUID.

    As an alternative you can also use the truncatememory command and see if that works, although truncatememory isn't as efficient as removememory. For example...
    bcdedit /set {18b123cd-2bf6-11db-bfae-00e018e2b8db} truncatememory 1024
