A program to force Vista 64 to see less than 4GB of memory?
I have a TV tuner card that is incompatible with anything over 3GB of RAM and I need to trick Vista 64 into thinking there is only 3GB instead of 8GB and I would prefer not to have to remove 3 sticks of memory just to watch tv. I wouldn't be opposed to rebooting the computer to switch it back and forth.
Any one heard of a program that can do this?

So autoexec is the batch file that controls booting, so I can make a batch file that copies a autoexce.bat from C:/3gb/autoexec.bat and one that copies from C:/8gb/autoexec.bat to replace whatever is the current batch file. Then it would be like a button and a reboot.
Closest one to a viable solution gets the points.

The answer to your question isn't an easy one but I have a similar problem. Here is what I am working out with my system right now.
I currently run an X58 EVGA motherboard with 3 sticks of DDR3 1600. I have Windows Vista Ultimate 32bit installed as the primary OS and I have a 1TB hard drive. As you may already know, 32bit OS can't utilize DDR3 Triple Channel memory for the 3GB of RAM total. It will only utilize 2GB of the RAM. Even though the system properties says 3GB, the Task Manager only sees 2048 RAM total.
I think this is due to 2 conditions, 1.) 32bit OS and 2.) Triple Channel DDR3.
SO, I have just bought Windows 7 64 bit and have partitioned my hard drive with a 200GB diskpart. leaving Vista Ultimate with ~740GB and Windows 7 with ~199GB. The thing here is that Windows 7 64bit will see all 3GB of RAM and will utilize the Triple Channel features of the DDR3 memory.
The Pain in the @$$ part about this is that I have my whole life stored in Vista Ultimate 32bit (Apps, Files, and Web Server configuration) so I can't just up and remove Vista 32bit.
Thankfully there is a neat feature built into the Windows 7 OS. A boot manager! Thankfully the folks at Microsoft finally realize that there are some of us around that can't just up and format our drives to get the 64 bit OS.
My advice to you is, start with a 32bit OS that wont see more than 3GB and use a 64bit OS as a second boot. You could accomplish this with a 32bit version of 7 and keep your 64bit Vista.
