I wonder if anyone can help me. I've searched exhaustively on this subject and haven't found a definate answer.
I have recently purchased a Samsung R720 (PS02UK) laptop with Windows 7 32bit Home Premium (OEM of course). The processor is a Core 2 Duo (P7450 - 64bit compliant). The computer came supplied with 4GB of RAM and has a 1GB dedicated video card.
Now my problem is obviously Windows can't address all this RAM (about 0.8-1.2GB is sitting hardware reserved for video memory, giving me over 2GB for the graphics card to use - which is pointless, it doesn't need that much!!)
OK, so my question is how can I move to 64bit Windows 7 without buying a full retail version. The OEM key is only suitable for 32bit versions (I called Samsung and asked). Will using an upgrade package work in this case? I am aware that it will be a custom install and as such will be a fresh install - this doesn't bother me as it is a new computer.
I have a copy of Windows 7 Professional 64bit upgrade to hand that I can use if it is possible. I obviously don't want to shell out for a full version just for 64bit, I don't think that would be worth it.
If anyone has any clue on this I would be very grateful to hear from you as I really don't know how to proceed!
