Send it back. Unless the game has a 64-bit client, or is specifically written to have 64-bit memory extensions, even running on Vista x64, it won't be able to use more than about 3.5GB of RAM.
BOTH the program AND the operating system have to be 64-bit for it to work. So unless you know for sure that the games you want to play are designed to be able to do 64-bit memory addressing, save yourself some money and send the extra copy of Vista back before you activate it. Same with the second hard drive, unless you have some other use for it.
Hey all, first time poster here.
I am currently running Vista Home Premium 32-bit, and I have a copy of the 64-bit version coming in the mail soon. I ordered 64-bit so that I can use more than 4GB of RAM for gaming.
Anyway, I want to keep my current 32-bit version intact, so I have acquired a 2nd SATA hard drive and want to install the 64-bit version on that and be able to dual-boot from the different Hard Drives.
So my question is, how do I go about doing this? Is it as simple as just telling the 64-bit Vista to install on the secondary HDD and then choose which install I want on boot-up?
