Hey guys, I was wondering if I am able to get full 4.00 GB ram on my system. (in my sig) I've been running 64 bit Windows 7 Ultimate, but anything I do its always 3.5 usable.

My Windows index is 5.0
CPU: 5
RAM: 5
Graphics: 6.9
Gaming Graphics: 6.9
Primary Hard disk 5.7

On my computer specs from HP, the specs said I can use up to 4GB, 1 GB per slot.

Under task manager in performance,
Total: 3582
Cache: 835
Available: 2339
Free: 1588

Btw, it can't be my integrated GPU because it only takes 256mb.

Hmmmm are you sure the windows is 64bit? Right click on my computer and choose properties and verify this.

The Intel ® 945G Express Chipset is not listed as supporting memory remapping.

Chipsets Support Memory Remapping

INTEL 955x, 975x, P965/G965, P35/G33…and perhaps all future chipsets
Various server platforms
AMD All the chipsets support Athlon64 939 or newer
Nvidia 650i/680i SLI(for Intel)

There's some other troubleshooting steps in there though, as well (checking BIOS to make sure it's all recognized, making sure it's in dual-channel mode, etc.) besides just checking for memory mapping. Maybe a BIOS update is available as well.

Yes I am sure that it is the 64bit version of Windows 7 (See Link)

On the other forum, I was informed about memory mapping, but when I entered my BIOS a lot of my options were locked. So I couldn't find memory mapping.

I actually don't know how to find the update for this BIOS, because I screwed it up once. Are you able to help me find it ? It is running version 5.17.
