I recently upgraded my old (945GM) chipset notebook memory ...

added 2x2G DDR2 800

while Intel says 945GM supports upto 4G of RAM , the Bios only recognized 3G in dual channel mode.

the System in Windows , says 4G of RAM ... and 3 in use .

the Graphics is not stealing the missing 1G here , when I put 2x1G it says 2G total in bios ..

any thoughts?

I already updated the Bios ... and I know that 32bit old cpu can handle and address 4G of Ram ..

And one last Question ,

Can I use the 4G without any stability problems given that the bios onle see 3 G of ram ?

intel mb can only see 3.2g out of 4g of ram. it because of how intel and the pci bridge and devices are set up. so your mb is right in posting only three 3g of ram. you can see if there a newer bios out there but i would not do anything to your old pc.
