Refuses to install/run with 3GB RAM
I have purchased Windows7 Proessional edition and am doing a clean install, though I have encountered a number of perplexing problems:
1. Windows7 refuses to install if the system has more than 2GB RAM installed. It hangs at
the 'Starting Windows' screen. I got past this by reducing RAM to 2GB - but why is this ?
2. Readjust my RAM to 3GB and reboot. Windows7 gets to the 'Starting Windows' screens, then
reboots the machine. Just refuses to accept 3GB RAM !
3. Attempt to enter via Safe Mode, but I can't as it also reboots
4. I set RAM back to 2GB and rebooted in Safe Mode. I then set the Maximum Memory in the
msconfig tool to 3072 MB and shutdown the machine. (as I clicked OK, it quickly flicked to
2048MB before closing the screen !)
5. Install 3GB RAM and reboot - all ok
6. Resource Monitor shows that 1GB is being used for hardware. (When I booted using 2GB RAM, only 1MB was reserved for hardware !)
Now, if I run with 2GB RAM installed or 3GB RAM there is no difference - only 2GB is
available for Windows 7. I find that rather weird.
I had Windows XP with the same 3GB RAM running before - with no RAM being reserved for hardware.
Motherboard : Gigabyte 7N400 Pro2 (revision 1) with latest BIOS (F11)
CPU : AMD Athlon XP 3200+
RAM : 3x 1GB Kingston HyperX PC3200 - running at 333MHz in dual channel mode
Video : nVidia FX5200 with 128MB dedicated RAM
Any ideas ?
