FE-590 to 4GB RAM

I need help getting my laptop ready for Win 7 (64 bit)... I would like to install 4GB of RAM but I'm running into some issues....

I have the FE-590, which I managed to upgrade the CPU to a T7600. I'm also running R0200J3 BIOS, which was originally for the FE890, but it is working great on mine. I believe that the BIOS for all FE laptops may be compatible across the FE line. I also enabled VT. The laptop runs great but I only have 2GB of RAM (2x1GB).

I bought 4GB of RAM (2x2GB). When I install it, the BIOS will recognize it and POST just fine. Win XP (32 bit) starts up fine with the "progress crawler" but then when it is time for the normal XP logon screen to appear, nothing ever shows up on my screen. However, the disk activity light continues to blink indicating that the XP load is still going on. Eventually, the disk activity light goes out and still nothing on the screen.

When I go back to just using 1 of the 2GB sticks, the machine boots up fine. I tried each memory stick individually and they work just fine. I also added /PAE to the boot.ini but same result.

I know the FE590-FE890 specs list 2GB as the max RAM allowed. But I am running the 945GM/PM chipset which is supposed to allow 4GB.

I also tried re-installing Win XP on a different hard drive and everything works fine thru the install until the machine does the first reboot to complete the XP install. At that point, nothing shows up on the screen....

My computer has the nvidia geForce Go 7400 running 179.48. Also running the latest intel chipset (9.1.1.1019).

I don't know what else to try. Does anybody have any suggestions? Am I really stuck with just 2GB?

Thanks,
MM

 

32 bit OS's only see max of 3GB RAM. I have Windows 7 running on a system with 1GB RAM fine.

 

Yes, I understand the issue with the 3GB limit. Microsoft lists 2GB as the recommended RAM for Win 7 (x64). Nice to see that it will run with just 1GB.
I would like to be able to push my FE590 to 4GB... We'll see. Thanks.
