RAM issue on Win7 64bit

  Dazza76 18:22 29 Dec 2009

I'm running the 64bit version of Windows 7 and I have 4gb of RAM on the mother board. However the system is only showing 2.9gb of usable RAM. This is less than it was showing on 32bit Vista. Any ideas?

Have you got integrated graphics, as more will be used because it is available

I think so yes. Is there any way of limiting how much use the graphics card sucks up? It's a Nvidia GeForce 8600 GTS

Thanks for the responses but I've still got the same problem. The initial suggestion didn't work and I can't find the BIOS options that were mentioned. I have an Asus Commando mother board....might the options be worded differently?

I assume you do not have a dual boot set up with XP or Vista? I had your problem when on dual boot.

No John, just Win 7 64bit

In Control Panel, System,what does it say in "installed Memory"?Does it say 4 Gig but only 2.9 available?

Yes, 4gb installed but only 2.94 available.

This was the same thing I had with dual boot. My local helper who solved it is away until Tuesday but I will ask him how he solved it - I think it was a BIOS update.. JB
