Hello every one. Just another windows 7 user here. I updated my XP 32 OS to windows 7 64 bit professional. Everything works fine on this upgrade. BUT when i go >start>mycmputer>right click and select properties i see 6 gigs but only 3.25 GB usable. Any way i can use the rest of those gigs. When i bought windows 7 two days ago i bought 2 stick of ram with 2 gigs each stick. so i have (2) 1 gig stick and (2) 2 gig sticks.

Like i sed my PC (Alienware was built in Dic2005) originally was made with 32 OS xp if someone can guide me on how to get my info of my mother board I will be glad to follows those steps so i can post them here and hopefully gets some help. If not I just will return the extra gigs I bought.

PS- I reinstall windows 7 from scratched but with OS 32 bit and I could see the same 6 gigs but only 3.25 gigs usable.


Thanks!

Need more info to go on. It could very well be that your mobo can only handle 4 GB. Looking at the support info for your patrticular computer on Alienware's site might also give you the answer you seek.

My thoughts are that this may be a BIOS issue. I had a similar problem when I upgraded my RAM memory to 4Gb.

Look in your BIOS for a "Memory Remap Feature" which will probably be disabled. Enable this and Windows should see and be able to access all avaiable memory.

The downside is that you may need to reinstall Windows 7 64bit for this to work.

windows 7 32bit will only read up to 3.xx gbs of ram anyway. sounds like a possible bios issue. get into your bios and see how many gbs bios sees. it may be something as simple as performing a bios upgrade if it only sees 4gbs for it to see the full 6gbs.

Are you referring to where it says "Total", "En Cache" and "Disponible"?

You're task manager is reporting your RAM correctly. You have 4GB available. 2.5GB is being cached with SuperFetch (which is what Windows 7 does), and you have 2.5GB RAM available to use. The 42MB of RAM you have free is the amount not being used by SuperFetch.

I had the same problem except I only had 4 GB of RAM installed.

To fix it, I had to enabled the following in my BIOS:
S/W Memory Hole Mapping
H/W Memory Hole Mapping

Hope it helps
