Built in ram limit for 64 bit

Hey all,

I have been thinking about getting a new computer, and the motherboard I am looking at is capable of holding up to 8 Gb of ram. Now it appears as though for 32 bit linux, in order to use more than 4 Gb of ram, you had to enable a certain option in the kernel, but if I remember correctly, there was also a performance hit for doing so. Of course I will be going 64 bit, and so I am wondering if there will be any problems with > 4 Gb of ram? Or will Linux take care of everything in 64 bit mode?

NAME
pilot-getram - Retrieves the RAM image from your Palm device for use in debugging. SECTION
pilot-link: Tools SYNOPSIS
pilot-getram [-p|--port <port>] [--version] [-q|--quiet] [-?|--help] [--usage] [-t|--token token] [-s|--sysinfo] [--ram] [--rom] [file- name] DESCRIPTION
pilot-getram is used to fetch the current RAM image from your Palm handheld for use in debugging. pilot-getromtoken, pilot-getrom and pilot-getram are inter-related. All relevant code is implemented in pilot-getrom, and you can do pilot-getromtoken --ram filename to get the RAM dump if you like. Note, because pilot-getrom uses the low-level RPC protocol to fetch the ROM image, and the new OS5 devices do not use this protocol, you currently cannot fetch an OS5 ROM image using this utility. This will be updated in a future release to handle fetching OS5 ROM images, using the debugger protocol. OPTIONS
pilot-getram options -t, --token token A ROM token to read (i.e. snum) -s, --sysinfo Print SysInfo --ram Read RAM --rom Read ROM <filename> Write the RAM image to the file named by <filename>. If this is omitted, the filename will be written out as the RAM version name as fol- lows: ' pilot-$VERSION.ram ', where an OS 3.5 image would be written as the filename of 'pilot-3.5.0.ram'. Conduit Options -p, --port <port> Use device file <port> to communicate with the Palm handheld. If this is not specified, pilot-getram will look for the $PILOTPORT environ- ment variable. If neither are found or supplied, pilot-getram will print the usage information. -q, --quiet Suppress 'Hit HotSync button' message -v, --version Display version of pilot-getram and exit without connecting. Help Options -h, --help Display the help synopsis for pilot-getram and exit without connecting. --usage Display a brief usage message and exit without connecting. USAGE
Connect to a target Palm handheld and fetch the RAM from the device. AUTHOR
