Windows 7: Dell Inspiron 1721

B3astiie · 11 Nov 2009

Hello Again,

Most of you know and remember me from the Dell Inspiron 1721 problem installing Windows 7. I was successfully able to install 64 bit Windows 7 after working around some things, but now I have a new question.

I have a AMD Truion 64x2 processor and currently running 3 gigs of ram, (2.75) usable. My question is...

How much ram can my 64bit laptop recognize and use?

Would like to know before I buy more ram.

Since you are running a 32bit OS, your OS can recognize all the 3 GB RAM. If you add one more gig, it may not recognize as 4 GB. Instead, it will recognize
Total RAM-Video RAM.
For ex: If you install 4 GB RAM and you have a 512MB Graphics card, it will recognize 3.5GB RAM.
