Re: 32bit OS cannot see 4GB of RAM on modern chipset



Impossible.

XP 32 and Vista 32 has a politicail limitation by MS to not support 64bit
physical addresses.

Use Server 2003 (at least Std sees all memory, dunno on Web) or any 64bit
Windows.

I have a machine built on Intel G33 chipset (Asus P5K-V mobo).

64bit OS (2003 R2 SP2 Ent) sees all 4GB of really present RAM.

32bit OS (XP SP2 Pro) sees only 3.24GB of RAM, with PAE on.

Why is this? Any chances of fixing this by tuning some OS registry
settings
or the BIOS settings?
